PRETORIA, South Africa, Nov 19 (IPS) – World Toilet Day 2023, on 19 November, focusing on ‘Accelerating Change’ – Toilets are a foundation stone of public health and play a critical role in protecting the environment”Celebrated annually on the 19th of November, World Toilet Day aims to inspire concerted efforts in addressing the pressing global sanitation crisis, which currently leaves approximately 3.5 billion people without access to safely managed sanitation.
Even today, a staggering 3.5 billion individuals lack safely managed sanitation, and an appalling 419 million people continue to use ‘open defecation’, a condition that encourages the spread of diseases and claims the lives of 1,000 children under the age of five daily. This sanitation crisis, a hazard to human health and the environment, disproportionately affects women, girls, and other vulnerable groups.
Given the fact that only seven years remain to attain the 2030 target for Sustainable Development Goal 6 – ensuring safe water for all – the global community needs to accelerate its efforts to ensure that the 2030 agenda is realized.
Our current pace, coupled with insufficient funds, escalating demand, deteriorating water quality, and the inadequacies of existing governance frameworks, gravely threatens the realization of this goal.
In alignment with this year’s theme – ‘Accelerating Change’ – it’s imperative that we expedite our global efforts to achieve the UN’s 2030 target. Governments and major institutions must synergistically operate, take accountability for their promises, and timely deliver on them. Actually, every individual, regardless of their contributions’ scale, has a role in accelerating this progress.
Implications of poor sanitation
The implications of poor water and sanitation are widespread and deleterious, gravely affecting individuals who are forced to use unsanitary toilet facilities or consume and utilize contaminated water. Diseases linked to sanitation, like diarrheal diseases, cholera, typhoid fever, hepatitis A, and various parasitic infections, pose significant public health risks.
These illnesses can result in extensive sickness, hospitalizations, and even fatalities, particularly in areas with sparse access to clean water and adequate sanitation facilities. Enhancements of sanitation infrastructure can decrease these disease burdens and elevate public health globally.
Benefits of good sanitation
Absolutely, having good sanitation facilities indeed has numerous benefits. They go beyond the improvement of public health. Proper sanitation infrastructure can reduce healthcare costs as there are fewer cases of sanitation-related diseases. It can also increase productivity as individuals are healthier and can devote more time to work. studies, or other activities.
This results in a better quality of life for individuals and their communities. Furthermore, good sanitation infrastructure contributes to environmental sustainability. It aids in reducing pollution since waste is properly managed and does not end up contaminating water bodies and other natural environments. A safe and clean environment, in turn, helps protect vital natural resources, including clean water sources.
Collaborative efforts
Governments, donors, the private sector, and non-governmental organizations all play significant roles in advancing sanitation infrastructure. They need to cooperate and work cohesively towards delivering water and sanitation services effectively. Furthermore, research institutions can contribute by providing the necessary scientific understanding and technological innovations. This joint endeavour will not just help in achieving the 2030 Agenda for Sustainable Development, specifically Goal 6, but also improve public health and well-being on a global scale.
SADC-GMI’s efforts
SADC-GMI has made commendable efforts by implementing various projects in SADC Member States to ensure everyone has access to water and sanitation as per the United Nations Agenda 2030. These initiatives have positively impacted local communities by ensuring a continuous water supply which ultimately leads to better hygiene. Beyond hygiene, these water supply projects have also brought about improved economic benefits for the communities. Indeed, the projects are transformative, aiding communities in gaining access to dependable water supply for both domestic and economic uses.
These projects, despite the complications posed by climate change, continue to thrive and be sustainable. This resilience greatly benefits communities, offering steady water for various needs. This ties into reaching the sanitation goals defined by the United Nations Agenda 2030.
Yes, with the 2030 deadline of the United Nations Sustainable Development Goals approaching, fast progress is needed to ensure everyone has access to basic sanitation facilities and clean water. Sanitation and drinking water are human rights, and access to these services is crucial for people’s health and the integrity of the environment. To this end, cooperation between different sectors – governments, donors, the private sector, research institutions, and civil society will be critical in facilitating this progression.

Community Efforts Boost Wastewater Treatment in El Salvador
by Edgardo Ayala (chirilagua, el salvador)
Inter Press Service
CHIRILAGUA, El Salvador, Nov 07 (IPS) – Neither the central government nor most of El Salvador’s 262 municipalities have had the capacity to install enough wastewater treatment plants to prevent it from being discharged directly into the environment.
As a result, most of the rivers are polluted to such a degree that only 12 percent of them have good quality water, and the pollution translates into gastrointestinal and other diseases among the 6.7 million inhabitants of this Central American country.
But there are some towns and cities that are making efforts to keep running the treatment plants they have managed to set up, with financial support from international institutions.
One of these municipalities is Chirilagua in eastern El Salvador, along the Pacific Ocean in the south, the only ocean that bathes the coast of this Central American isthmus country.
The municipality operates a wastewater treatment plant built in the surrounding area as part of a 40-unit housing project called La Española that houses 40 families affected by Hurricane Mitch, which caused death and destruction in Central America in October 1998.
The project was largely financed with funds from the government of the southern Spanish region of Andalucía.
“The benefit is to the environment and to the families living around here, because the less the environment is polluted the healthier the population is,” Eduardo Ortega, in charge of the plant’s maintenance, told IPS.
The treatment plant filters the sewage that arrives at the station, using various processes, including ponds filled with volcanic soil and gravel.
“The aim is to keep the treated water from polluting the San Roman River,” said Edwin Guzman, head of the Environmental Unit of the municipality of Chirilagua.
Close to the municipality is another rural settlement also built by Spanish aid funds for survivors of Hurricane Mitch, called Flores de Andalucía, which includes its own treatment plant.
With greater capacity, this station also receives sewage from El Cuco, a fishing village three kilometers to the south on a beach that due to population growth has become a town with modest stores, hostels and restaurants that receive tourists attracted by its gray sand beaches and gentle waves.
In El Salvador, only 8.52 percent of wastewater receives some type of treatment, and much of the waste is dumped into the different bodies of water, polluting ecosystems and harming people’s health. Now some communities and municipalities have managed to install treatment plants that are run by local residents and improve their lives.

LIMA, Oct 26 (IPS) – The lack of water is so severe in Peru’s highlands that farming families are forced to sell their livestock because they cannot feed them. “There is no grass or fodder to feed them,” says Fermina Quispe, a Quechua farmer from a rural community located at 4,200 meters above sea level.
Llarapi Chico, the name of her community, belongs to the district of Arapa in the southern Andean department of Puno, one of the 14 that the government declared in emergency on Oct. 23 due to the water deficit caused by the combined impacts of climate change and the El Niño phenomenon.
Arapa is home to 9,600 people in its district capital and villages, most of whom are Quechua indigenous people, as in other districts of the Puna highlands.
With a projected population of more than 1.2 million inhabitants, less than four percent of the estimated national population of over 33 million, Puno has high levels of poverty and extreme poverty, especially in rural areas.
According to official figures, in 2022 the poverty rate in the department stood at 43 percent, compared to 40 percent and 46 percent in 2020 and 2021, respectively – years marked by the impact of the COVID-19 pandemic. The recession of the Peruvian economy could drive up the poverty rate this year.
In addition, Puno was shaken by the impunity surrounding nearly 20 deaths during the social protests that broke out in December 2022 demanding the resignation of interim President Dina Boluarte, who succeeded President Pedro Castillo, currently on trial for attempting to “breach the constitutional order”.
The United Nations issued a report on Oct. 19 stating that human rights violations were committed during the crackdown on the protests, one of whose epicenters was Puno.
Fermina Quispe is president of the Women’s Association of Huerto de Nueva Esperanza, which is made up of 22 women farmers who, like her, are getting involved in agroecological vegetable production with the support of the non-governmental organization Cedepas Centro.
The 41-year-old community leader spoke to IPS in Chosica, on the outskirts of Lima, while she participated in the Encuentro Feminismos Diversos por el Buen Vivir (Meeting of Diverse Feminisms for Good Living), held Oct. 13-15.
With a soft voice and a face lit up with a permanent smile, Quispe shared her life story, which was full of difficulties that far from breaking her down have strengthened her spirit and will, and have helped her to face challenges such as food security.

As a child she witnessed the kidnapping of her father, then lieutenant governor (the local political authority) of the community of Esmeralda, where she was born, also located in Arapa. Her father and her older brother were dragged away by members of the Maoist guerrilla group Sendero Luminoso (Shining Path), which unleashed terror in the country between 1980 and 2000.
“A month later we found my father, they had tortured him and gouged out his eyes. My mother, at the age of 40, was left alone with 12 children and raised us on her own. I finished primary and secondary school but I couldn’t continue studying because we couldn’t afford it, we had nowhere to get the money,” she recalls calmly. Her brother was never heard from again.
She did not have the opportunity to go to university where she wanted to be trained as an early childhood education teacher, but she developed her entrepreneurial skills.
After she married Ciro Concepción Quispe – “he is not my relative, he is from another community,” she clarifies- they dedicated themselves to family farming and managed to acquire several cattle and small livestock such as chickens and guinea pigs, which ensured their daily food.
Her husband is a construction worker in Arapa and earns a sporadic income, and in his free time he helps out on the farm and in community works.
Their eldest daughter, Danitza, 18, is studying education at the public Universidad Nacional del Altiplano in Puno, the departmental capital, where she rents a room. And the youngest, 13-year-old Franco, will finish the first year of secondary school in December. His school is in the town of Arapa, a 20-minute walk from their farm.
Fermina managed to build “my own little house” on a piece of land she acquired on her own and outside of her husband’s land, in order to have more autonomy and a place of her own “if we have conflicts,” she says.
She also began to look for information about support for farming families, bringing together her neighbors along the way. This is how the association she now presides over came into being.
However, the drought, which has not let up since 2021, is causing changes and wreaking havoc in their lives, ruining years of efforts of families such as Fermina’s.
“We have a water crisis and the families are very worried. We are not going to have any production and the cattle are getting thin, we have no choice but to sell. A bull that cost 2,000 soles (519 dollars) we are selling off for 500 (129 dollars). The middlemen are the ones who profit from our pain,” she says.

Solar water pumps
In the face of adversity, “proposals and action” seems to be Quispe’s mantra. She wants to strengthen her vegetable production for self-consumption and is thinking about growing aromatic herbs and flowers for sale. To do so, she needs to ensure irrigation in her six-by-thirteen-meter highland greenhouse where she uses agroecological methods.
During her participation in Cedepas Centro’s training activities, she learned about solar water pumps, which make it possible to pump water collected in rustic wells called “cochas” to gardens and fields. She has knocked on many doors to raise funds to set up solar water pumps in her community.
“Fermina’s gardens and those of 14 other farmers in her community now have solar pumps for irrigation and living fences made of Spanish broom (Cytisus racemosus),” José Egoavil, one of the experts in charge of the institution’s projects, told IPS.
“They are small pumps that run on 120- to 180-watt solar panels,” he says in a telephone interview from Arapa.
He explains that the solar panel is connected to the pump, which sucks the water stored in the wells that the families have dug, or in the “ojos de agua” – small natural pools of springwater – present on some farms. Thus, they can irrigate the vegetable crops in their greenhouses, and the living fences.
“It is a sustainable technology, it does not pollute because it uses renewable energy and maintenance is not very expensive. In addition, the families give something in return, which makes them value it more. Of the total cost of materials, which is about 900 soles (230 dollars), they contribute 20 percent, in addition to their labor,” he says.
Egoavil, a 45-year-old anthropologist, has lived in Arapa for three years. He is from Junín, a department in the center of the country where Cedepas Centro, an organization dedicated to promoting food security and sustainable development in the Andes highlands of central and southern Peru, is based,
“The focus of our work is on food security and a fundamental issue is water for human consumption and production. There have already been two agricultural seasons in which we have harvested much less and we are about to start a new one, but without rain the forecasts are not encouraging,” he says.
Given the water shortage, they have promoted the community participation of families in emergency projects such as solar pumps, which help to ensure their food supply.
In addition, long-range water seeding and harvesting works are underway, such as the construction of infiltration ditches at the headwaters of river basins.
The participation of small farming families is the driving force behind the works and they are responsible for identifying the natural water sources for their conservation and the construction of the ditches that will prevent the water from flowing down the hills when it rains.
“The ditch is like a sponge that retains water, but if it doesn’t rain, we don’t know what will happen,” says Egoavil.

Learning to harvest water
Jesusa Calapuja, a 27-year-old veterinarian born in Arapa, is one of the people in charge of technical assistance in agroecological production, planting and water harvesting at Cedepas Centro.
Using the Escuela de Campo (countryside school) methodology, she travels by motorcycle to the different communities where she interacts with farming families. She came with Fermina Quispe to the feminist meeting in Chosica, where IPS interviewed her.
Calapuja also notes changes in the dynamics of the population due to water scarcity. For example, their production no longer generates surpluses to be sold at the Sunday markets; it is barely enough for their own sustenance.
“They don’t have the income to buy what they need,” she says.
She also notices that at training meetings, women and men no longer bring their boiled potatoes or soup made with the oca tuber, or roasted corn for snacks, but only chuño (dehydrated potatoes) or dried beans. The scarcity of their tuber and grain production is evident in their diets.
But Fermina Quispe hastn’t lost her smile in the face of adversity and is confident that her new skills will help the women in her community.
“Our great-great-grandparents harvested water, made terraces and dams; we have only been harvesting, collecting and using. But it won’t be like that anymore and we are taking advantage of the streams so the water won’t be lost. We only hope that the wind does not carry away the rain clouds,” she says hopefully.

MEXICO CITY, Oct 24 (IPS) – The defense of the right to water led Gema Pacheco to become involved in environmental struggles in the southern Mexican state of Oaxaca, an area threatened by drought, land degradation, megaprojects, mining and deforestation.
Care “means first and foremost to value the place where we live, that the environment in which we grow up is part of our life and on which our existence depends,” said Pacheco, deputy municipal agent of San Matías Chilazoa, in the municipality of Ejutla de Crespo, some 355 kilometers south of Mexico City.
The local population is dedicated to growing corn, beans and chickpeas, an activity hampered by the scarcity of water in a country that has been suffering from a severe drought over the past year.
To deal with the phenomenon, the community created three water reservoirs and infiltration wells to feed the water table.
“Women’s participation has been restricted, there are few women in leadership positions. The main challenge is acceptance. There is little participation, because they see it as a waste of time and it is very demanding,” lamented Pacheco.
But women activists like Pacheco face multiple threats for protecting their livelihoods and culture in a country where such activities can pose a lethal risk.
For this reason, eight organizations from five Mexican states launched the Voices of Life campaign on Oct. 12, involving hundreds of habitat protectors, some of whom came to the Mexican capital for the event, where IPS interviewed several of them.

The initiative seeks to promote the right to a healthy environment, facilitate environmental information, protect and recognize people and organizations that defend the environment, as well as learn how to use information and communication technologies.
In 2022, Mexico ranked number three in Latin America in terms of murders of environmental activists, with 31 killed (four women and 16 indigenous people), behind Colombia (60) and Brazil (34), out of a global total of 177, according to the London-based non-governmental organization Global Witness.
A year earlier, this Latin American country of almost 129 million inhabitants ranked first on the planet, with 54 killings, so 2022 reflected an improvement.
“The situation in Mexico remains dire for defenders, and non-fatal attacks, including intimidation, threats, forced displacement, harassment and criminalization, continued to greatly complicate their work,” the report says.
The outlook remains serious for activists, as the non-governmental Mexican Center for Environmental Law (Cemda) documented 582 attacks in 2022, more than double the number in 2021. Oaxaca, Mexico City and the northern state of Chihuahua reported the highest number of attacks.
Urban problems
The south of Mexico City is home to the largest area of conservation land, but faces growing threats, such as deforestation, urbanization and irregular settlements.
Protected land defines the areas preserved by the public administration to ensure the survival of the land and its biodiversity.
Social anthropologist Tania Lopez said another risk has now emerged, in the form of the new General Land Use Planning Program 2020-2035 for the Mexican capital, which has a population of more than eight million people, although Greater Mexico City is home to more than 20 million.
“There was no public consultation of the plan based on a vision of development from the perspective of native peoples. In addition, it encourages real estate speculation, changes in land use and invasions,” said López, a member of the non-governmental organization Sembradoras Xochimilpas, part of the Voices of Life campaign.

Apart from the failure to carry out mandatory consultation processes, activists point out irregularities in the governmental Planning Institute and its technical and citizen advisory councils, because they are not included as members.
The conservation land, which provides clean air, water, agricultural production and protection of flora and fauna, totals some 87,000 hectares, more than half of Mexico City.
The plan stipulates conservation of rural and urban land. But critics of the program point out that the former would lose some 30,000 hectares, destined for rural housing.
The capital’s legislature is debating the program, which should have been ready by 2020.
Gisselle García, a lawyer with the non-governmental Interamerican Association for Environmental Defense, said attacks on women activists occur within a patriarchal culture that limits the existence of safe spaces for women’s participation in the defense of rights.
“It’s an entire system, which reflects the legal structure. If a woman files a civil or criminal complaint, she is not heard,” she told IPS, describing the special gender-based handicaps faced by women environmental defenders.

Still just an empty promise
This risky situation comes in the midst of preparations for the implementation of the Regional Agreement on Access to Information, Public Participation and Justice in Environmental Matters in Latin America and the Caribbean, known as the Escazú Agreement, an unprecedented treaty that aims to mitigate threats to defenders of the environment, in force since April 2021.
Article 9 of the Agreement stipulates the obligation to ensure a safe and enabling environment for the exercise of environmental defense, to take protective or preventive measures prior to an attack, and to take response actions.
The treaty, which takes its name from the Costa Rican city where it was signed, guarantees access to environmental information and justice, as well as public participation in environmental decision-making, to protect activists.
The Escazú Agreement has so far been signed by 24 Latin American and Caribbean countries, 15 of which have ratified it as well.
But its implementation is proceeding at the same slow pace as environmental protection in countries such as Mexico, where there are still no legislative changes to ensure its enforcement.
Meanwhile, in Mexico, the Escazú National Group, made up of government and civil society representatives, was formed in June to implement the treaty.
During the annual regional Second Forum of Human Rights Defenders, held Sept. 26-28 in Panama, participants called on the region’s governments to strengthen protection and ensure a safe and enabling environment for environmental protectors, particularly women.
While the Mexican women defenders who gathered in Mexico City valued the Escazú Agreement, they also stressed the importance of its dissemination and, even more so, its proper implementation.
Activists Pacheco and Lopez agreed on the need for national outreach, especially to stakeholders.
“We need more information to get out, a lot of work needs to be done, more people need to know about it,” said Pacheco.
The parties to the treaty are currently discussing a draft action plan that would cover 2024 to 2030.
The document calls for the generation of greater knowledge, awareness and dissemination of information on the situation, rights and role of individuals, groups and organizations that defend human rights in environmental matters, as well as on the existing instruments and mechanisms for prevention, protection and response.
It also seeks recognition of the work and contribution of individuals, groups and organizations that defend human rights, capacity building, support for national implementation and cooperation, as well as a follow-up and review scheme for the regional plan.
García the attorney said the regional treaty is just one more tool, however important it may be.
“We are in the phase of seeing how the Escazú Agreement will be applied. The most important thing is effective implementation. It is something new and it will not be ready overnight,” she said.
As it gains strength, the women defenders talk about how the treaty can help them in their work. “If they attack me, what do I do? Pull out the agreement and show it to them so they know they must respect me?” one of the women who are part of the Voices of Life campaign asked her fellow activists.

NITERÓI, Brazil, Oct 20 (IPS) – Houses with balconies facing the street or the surrounding hills, when they are not hidden behind high walls, reflect a neighborhood where people live on the shore of a lagoon but reject the landscape it offers.
Piratininga, a 2.87 square kilometer coastal lagoon in the southern part of the Brazilian city of Niterói, began to change after several decades of uncontrolled urban growth with no care for the natural surroundings, in what has become a neighborhood of 16,000 inhabitants.
Garbage, polluted water, construction debris and bad odors hurt the landscape and the quality of life that is sought when choosing a lagoon and green hills as a place to build a year-round or weekend residence.
The accumulated sludge at the bottom of the lagoon is 1.6 meters thick, on average, resulting from both pollution and natural sedimentation.
“That’s what explains those houses that turn their backs to the lagoon,” explained Dionê Castro, coordinator of the Sustainable Oceanic Region Program (PRO Sostenible) of the city government of Niterói, a municipality of 482,000 people separated from the city of Rio de Janeiro only by Guanabara Bay.
Oceânica is one of the five administrative zones of the municipality, locally called regions, which includes 11 neighborhoods in the southern part, on the open sea coast, in contrast to others on the shore of the bay or inland areas without beaches. With two lagoons and a good part of the Atlantic Forest still preserved, the area stands out for its nature.
PRO Sostenible, which was founded in 2014, seeks to restore environmental systems and to ensure better and more sustainable urbanization in the area. Its actions are based on a systemic approach and nature-based solutions.

Natural clean-up of the water
The program’s flagship project is the Orla Piratininga Alfredo Sirkis Park, which pays homage to a leader of the environmental movement, former national lawmaker and former president of the Green Party, as well as journalist and writer, who died in 2020.
The park, known by its acronym POP, has the mission of recovering and protecting the ecosystems associated with the Piratininga Lagoon, in addition to fostering a sense of belonging to the environment and its surroundings. For this reason, the participation of the local residents in all stages of the project has been and continues to be a basic principle.
It comprises an area of 680,000 square meters, the largest in Brazil in nature-based solutions projects, with 10.6 kilometers of bicycle paths, 17 recreational areas and a 2,800 square meter Ecocultural Center.
To bring residents and visitors closer to the local environment, the plan is to complete three three-story lookout points – two of which have already been built – and piers reaching into the lagoon, part of which can be used for fishing, as fish still inhabit the lagoon despite the pollution of recent decades.
The first section, known as Haciendita Cafubá, was inaugurated on Jun. 17, with a water filtration system for the Cafubá River, one of the three that flow into the lagoon, a lookout point, piers, a bicycle path and even a nursery for newborn crocodiles in a special fenced-in area.

“I went to see if I could find the crocodiles, my son made me walk down the street, he loves animals… I never thought I would see what I saw… I went to the beginning of the Haciendita, I saw fish where there was nothing living before, I saw flowers where there was only mud, I saw life where nature was already dead without any hope. Congratulations for tolerating us, that community is tough.”
This is the testimony of a resident, addressed to the head of PRO Sostenible. The park has had a large number of visitors since before its inauguration, attracted by flora and fauna that had long since disappeared from the shores of the lagoon.
The technology used to clean the waters is known around the world but has not been widely used in Brazil. It is based on filter gardens, in which layers of gravel and permeable substrates serve as a base for macrophytes, aquatic plants that live in flooded areas and are visible on the surface.
The plants filter the water in a process that does not require chemical inputs.
A special spillway receives the waters of the Cafubá, which conducts and controls them to give greater efficiency to the next pond, the sedimentation pond, the first step in cleaning the polluted waters by reducing the solid material produced by erosion and garbage thrown into the riverbed.
After the sedimentation basins, the water passes through three filtering gardens before flowing into the lagoon.

Plantfilters
Twelve species of macrophytes are used in the filtration process, but the variety has been reduced due to maintenance difficulties. “We use only Brazilian species, and no exogenous species,” said Heloisa Osanai, a biologist specialized in environmental management and one of the 17 employees of PRO Sostenible.
Examples include water lettuce and water lilies with orange flowers.
“One of the effects of the water treatment is the reduction of mosquitoes, which is important to local residents, who used to burn dry vegetation in an attempt to drive away the insects. People no longer build bonfires in the evenings. The filter gardens attract dragonflies that eat the mosquitoes,” said Osanai.
In the larger Jacaré River, 11 filtering gardens were created, which operate in sequence and whose size was designed for greater efficiency, said Andrea Maia, another biologist and environmental manager of the team.

Awards and results
PRO Sostenible has already won several national and international awards. It was named one of the three best environmental sustainability programs in Latin America and the Caribbean in the Smart Cities 2022 award.
This year it won another award from Smart Cities Latin America, as the best in Sustainable Urban Development and Mobility. The Park also won awards for valuing biodiversity, from the Federation of Industries of Rio de Janeiro, and another as an environmental project, from the São Paulo city government, for contributing to the Sustainable Development Goals of the 2030 Agenda.
In addition to the Park, the program has inaugurated a Sports and Leisure Center on the island of Tibau, on the other side of the Piratininga Lagoon, closer to the sea.
As part of this project, sports fields, a playground and a lookout point have been built, while an invasive tree, the white lead tree (Leucaena leucocephala), native to Mexico and Central America, which dominated the island’s vegetation, has been gradually replaced with local species.
The systemic thinking that guides PRO Sostenible is based on three pillars, explained Dionê Castro.
First is the complexity of local ecosystems and of the projects being implemented, focusing on the environmental, natural, social and cultural dimensions.
In second place is what is called “intersubjectivity”, which takes into account new paradigms of science, leaving behind “simplistic and Cartesian views…The changes do not come from outside, but from local residents, with public input from the conception of the project to its execution,” said the geographer who holds a doctorate in environmental management.
The third pillar is irreversibility. The lagoon and its ecosystems will not return to their original state, “to zero,” but will be cleaned up as much as possible to reach a “new equilibrium,” she said.
Local support for the environmental project led to solutions in different areas, such as the regularization of real estate in the favelas or shantytowns, the improvement of health, the revitalization of fishing, and even the creation of a fishermen’s association.
“It’s environmental justice on the march,” Castro summed up.
LIMA, Sep 28 (IPS) – Nearly 700,000 people have migrated internally in Peru due to the effects of climate change. This mass displacement is a clear problem in this South American country, one of the most vulnerable to the global climate crisis due to its biodiversity, geography and 28 different types of climates.
“We recognize migration due to climate change as a very tangible issue that needs to be addressed,” Pablo Peña, a geographer who is coordinator of the Emergency and Humanitarian Assistance Unit of the International Organization for Migration (IOM) in Peru, told IPS.
In an interview with IPS at the UN agency’s headquarters in Lima, Peña reported that according to the international Internal Displacement Monitoring Center, the number of people displaced within Peru’s borders by disasters between 2008 and 2022 is estimated at 659,000, most of them floods related to climate disturbances.
In this Andean country of 33 million inhabitants, there is a lack of specific and centralized data to determine the characteristics of migration caused by environmental and climate change factors.
Peña said that through a specific project, the IOM has collaborated with the Peruvian government in drafting an action plan aimed at preventing and addressing climate-related forced migration, on the basis of which a pilot project will begin in October to systematize information from different sources on displacement in order to incorporate the environmental and climate component.
“We aim to be able to define climate migrants and incorporate them into all regulations,” said the expert. The project, which includes gender, rights and intergenerational approaches, is being worked on with the Ministries of the Environment and of Women and Vulnerable Populations.
He added that this type of migration is multidimensional. “People can say that they left their homes in the Andes highlands because they had nothing to eat due to the loss of their crops, and that could be interpreted, superficially, as forming part of economic migration because they have no means of livelihood. But that cause can be associated with climatic variables,” Peña said.

The Central Reserve Bank, in charge of preserving monetary stability and managing international reserves, lowered in its September monthly report Peru’s economic growth projection to 0.9 percent for this year, partly due to the varied impacts of climate change on agriculture and fishing.
This would affect efforts to reduce the poverty rate, which stands at around 30 percent in the country, where seven out of every 10 workers work in the informal sector, and would drive up migration of the population in search of food and livelihoods.
“The World Bank estimates that by 2050 there will be more than 10 million climate migrants in Latin America,” said Peña.
The same multilateral institution, in its June publication Peru Strategic Actions Toward Water Security, points out that people without economic problems are 10 times more resistant than those living in poverty to climatic impacts such as floods and droughts, which are increasing at the national level.
The country is currently experiencing the Coastal El Niño climate phenomenon, which in March caused floods in northern cities and droughts in the south. The official National Service of Meteorology and Hydrology warned that in January 2024 it could converge with the El Niño Southern Oscillation (ENSO) global phenomenon, accentuating its impacts.
El Niño usually occurs in December, causing the sea temperature to rise and altering the rainfall pattern, which increases in the north of the country and decreases in the south.
The manager of Natural Resources of the Piura regional government, Juan Aguilar, described the vulnerability to climate change of this northern coastal region of Peru at a September meeting organized by the IOM in Lima. The official explained that the El Niño climate phenomenon has become more intense and frequent due to the effects of climate change, which aggravates its impacts on the population, such as severe flooding this year.

Reluctance to migrate to safer areas
Piura, a northern coastal department with an estimated population of just over two million inhabitants, has been hit by every El Niño episode, including this year’s, which left more than 46,000 homes damaged, even in areas that had been rebuilt.
Juan Aguilar, manager of Natural Resources of the Piura regional government, maintains that the high vulnerability to ENSO is worsening with climate change and is affecting the population, communication routes and staple crops.
At an IOM workshop on Sept. 5 in Lima, the official stressed that Piura is caught up in both floods and droughts, in a complex context for the implementation of spending on prevention, adaptation and mitigation.
Aguilar spoke to IPS about the situation of people who, despite having lost their homes for climatic reasons, choose not to migrate, in what he considers to be a majority trend.
“People are not willing overall to move to safer areas, even during El Niño 2017 when there were initiatives to relocate them to other places; they prefer to wait for the phenomenon to pass and return to their homes,” he added.

He explained that this attitude is due to the fact that they see the climatic events as recurrent. “They say, I already experienced this in such and such a year, and there is a resignation in the sense of saying that we are in a highly vulnerable area, it is what we have to live with, God and nature have put us in these conditions,” Aguilar said.
He acknowledged that with regard to this question, public policies have not made much progress. “For example after 2017 a law was passed to identify non-mitigable risk zones, and that has not been enforced despite the fact that it would help us to implement plans to relocate local residents to safer areas,” he added.
The regional official pointed out that “we do not have an experience in which the State says ‘I have already identified this area, there is so much housing available here for those who want to relocate’ , because the social cost would be so high.”
“We have not seen this, and the populace has the feeling that if they are going to start somewhere else, the place they abandon will be taken by someone else, and they say: ‘what is the point of me moving, if the others will be left here’,” Aguilar said.
Paulina Vílchez, 72, has always lived in the Peruvian municipality of Lurigancho-Chosica. Despite the fear every year that the Rimac River might flood and that mudslides could occur in one of the 21 ravines in the area, she has never thought of moving away. “I’m not going to go to an empty plot to start all over again, that’s why I’ve stayed. I leave everything in the hands of God,” she said. CREDIT: Mariela Jara / IPS
The fear of starting over
Some 40 km from the Peruvian capital, in Lurigancho-Chosica, one of the 43 municipalities of the province of Lima, the local population is getting nervous about the start of the rainy season in December, which threatens mudslides in some of its 21 ravines. The most notorious due to their catastrophic impact occurred in 1987, 2017, 2018 and March of this year.
Landslides, known in Peru by the Quechua indigenous term “huaycos”, have been part of the country’s history, due to the combination of the special characteristics of the rugged geography of the Andes highlands and the ENSO phenomenon.
In an IPS tour of the Chosica area of Pedregal, one of the areas vulnerable to landslides and mudslides due to the rains, there was concern in the municipality about the risks they face, but also a distrust of moving to a safer place to start over.
“I came here to Pedregal as a child when this was all fields where cotton and sugar cane were planted. I have been here for more than sixty years and we have progressed, we no longer live in shacks,” said 72-year-old Paulina Vílchez, who lives in a nicely painted two-story house built of cement and brick.
On the first floor she set up a bodega, which she manages herself, where she sells food and other products. She did not marry or have children, but she helped raise two nieces, with whom she still lives in a house that is the fruit of her parents’ and then her own efforts and which represents decades of hard work.
Vílchez admits that she would like to move to a place where she could be free of the fear that builds up every year. But she said it would have to be a house with the same conditions as the one she has managed to build with so much effort. “I’m not going to go to an empty plot to start all over again, that’s why I’ve stayed. I leave everything in the hands of God,” she told IPS.

She constantly worries that another catastrophe will happen again, and says she would relocate if she were guaranteed safer land and materials to build a new house. CREDIT: Mariela Jara / IPS
Very close to the Rimac River and next to the railway tracks that shake her little wooden house each time the train passes by lives Maribel Zavaleta, 50, born in Chosica, and her family of two daughters, a son, and three granddaughters.
“I came here in 1989 with my mom, she was a survivor of the 1987 huayco, and we lived in tents until we were relocated here. But it’s not safe; in 2017 the river overflowed and the house was completely flooded,” she told IPS.
Zavaleta started her own family at the age of 21, but is now separated from her husband. Her eldest son lives with his girlfriend on the same property, and her older daughter, who works and helps support the household, has given her three granddaughters. The youngest of her daughters is 13 and attends a local municipal school.
“I work as a cleaner and what I earn is only enough to cover our basic needs,” she said. She added that if she were relocated again it would have to be to a plot of land with a title deed and materials to build her house, which is now made of wood and has a tin roof, while her plot of land is fenced off with metal sheets.
“I can’t afford to improve my little house or leave here. I would like the authorities to at least work to prevent the river from overflowing while we are here,” she said, pointing to the rocks left by the 2017 landslide that have not been removed.

COQUIMBO, Chile, Sep 18 (IPS) – The reuse of treated wastewater in vulnerable rural areas of Chile’s arid north is emerging as a new resource for the inhabitants of this long, narrow South American country.
The Coquimbo region, just south of the Atacama Desert, one of the driest in the world, is suffering from a severe drought that has lasted 15 years.
According to data from the Meteorological Directorate, a regional station located in the Andes Mountains measured 30.3 millimeters (mm) of rain per square meter this year as of Sept. 10, compared to 213 mm in all of 2022.
At another station, in the coastal area, during the same period in 2023, rainfall stood at 10.5 mm compared to the usual level of 83.2 mm.
Faced with this persistent level of drought, vulnerable rural localities in Coquimbo, mostly dedicated to small-scale agriculture, are emerging as a new example of solutions that can be replicated in the country to alleviate water shortages.
The aim is to not waste the water that runs down the drains but to accumulate it in tanks, treat it and then use it to irrigate everything from alfalfa fields to native plants and trees in parks and streets in the localities involved. It is a response to drought and the expansion of the desert.
“We were able to implement five wastewater treatment projects and reuse 9.5 liters per second, which is, according to a comparative value, the consumption of 2,700 people for a year or the water used to irrigate 60 hectares of olive trees,” said Gerardo Díaz, sustainability manager of the non-governmental Fundación Chile.
These five projects, promoted by the Fundación Chile as part of its Water Scenarios 2030 initiative, are financed by the regional government of Coquimbo, which contributed the equivalent of 312,000 dollars. Of this total, 73 percent is dedicated to enabling reuse systems, for which plants in need of upgrading but not reconstruction have been selected.
The common objective of these projects, which together benefit some 6,500 people, is the reuse of wastewater for productive purposes, the replacement of drinking water or the recharge of aquifers.
Díaz told IPS that the amount of reuse obtained is significant because previously this water was discharged into a stream, canal or river where it was perhaps captured downstream.

A successful pilot experience
In Coquimbo, which has a regional population of some 780,000 people, there are 71 water treatment plants, most of which use activated sludge and almost all of which are linked to the Rural Drinking Water Program (APR) of the state Hydraulic Works Directorate.
Activated sludge systems are biological wastewater treatment processes using microorganisms, which are very sensitive in their operation and maintenance and rural sectors do not have the capacity to maintain them.
“Most of these treatment plants are not operating or are operating inefficiently,” Diaz acknowledged.
But one of the plants, once reconditioned, has served as a model for others since 2018. Its creation allowed Dionisio Antiquera, a 52-year-old agricultural technician, to save his alfalfa crop.
“We have had a water deficit for years. This recycled water really helps us grow our crops on our eight hectares of land,” he said in the middle of his alfalfa field in Cerrillos de Tamaya, one of the Coquimbo municipalities that IPS toured for several days to observe five wastewater reuse projects.

He explained that using just reused water he was able to produce six normal alfalfa harvests per year with a yield per hectare of 100 25-kg bales.
“That’s 4500 to 4800 bales in the annual production season,” he said proudly.
These bales are easily sold in the region because they are cheaper than those of other farmers.
The water he uses comes from an APR plant that has 1065 users, 650 of whom provide water, including Antiquera.
On one side of his alfalfa field is a plant that accumulates the sludge that is dehydrated in pools and drying courts, and on the other side, the water is chlorinated and runs into another pond in its natural state.
“This water works well for alfalfa. It is hard water that has about 1400 parts per million of salt. Then it goes through a reverse osmosis process that removes the salt and the water is suitable for human consumption,” the farmer explained.
In Chile, treated wastewater is not considered fresh water or water that can be used directly by people, and its reuse is only indirect.
Antiquera sold half a hectare to the government to install the plant and in exchange uses the water obtained and contributes 20 percent to the local APR.
He recently extended his alfalfa field to another seven hectares, thanks to his success with treated water.

Flowers and trees also benefit
In Villa Puclaro, in the Coquimbo municipality of Vicuña, Raúl Ángel Flores, 55, has an ornamental plant nursery.
“I’ve done really well. My nursery has grown with just reuse water….. I have more than 40,000 ornamental, fruit, native and cactus plants. I deliver to retailers in Vicuña and Coquimbo,” a port city in the region, he told IPS.
The nursery is 850 square meters in size, and has an accumulation pond and pumps to pump the water. He has now rented a 2,500-meter plot of land to expand it.
Flores explained to IPS that he manages the nursery together with his wife, Carolina Cáceres, and despite the fact that they have two daughters and a senior citizen in their care, “we make a living just selling the plants…I even hired an assistant,” he added.
In the southern hemisphere summer he uses between 4,000 and 5,000 liters of water a day for irrigation.
“I have water to spare. Here it could be reused for anything,” he said.
Joining the project made it possible for Flores to make efficient use of water with a business model that in this case incorporates a fee for the water to the plant management, which is equivalent to 62 cents per cubic meter used.

Eliminating odors, and creating new gardens
In the community of Huatulame, in the municipality of Monte Patria, Fundación Chile built an artificial surface wetland to put an end to the bad odors caused by effluents from a deficient waste-eater earthworm vermifilter treatment plant.
“This wetland has brought us peace because the odors have been eliminated. For the past year people have been able to walk along the banks of the old riverbed,” Deysy Cortés, 72, president of the APR, told IPS.
The municipality of Monte Patria is financing the repair of the plant with the equivalent of 100,000 dollars.
“The sprinklers will be changed, the filtering system will be replaced, and sawdust and worms will be added. It will be up and running in a couple of months,” explained agronomist Jorge Núñez, a consultant for Fundación Chile.
As in other renovated plants, safe infiltration of wastewater is ensured while the project simultaneously promotes the protection of nearby wells to provide water to the villagers.

Cortés warned of serious difficulties if no more rain falls in the rest of 2023, despite the relief provided by the plant for irrigation.
“I foresee a very difficult future if it doesn’t rain. We will go back to what we experienced in 2019 when in every house there were bottles filled with water and a little jug to bathe once a week,” she said.
During a recent crisis, the local APR paid 2500 dollars to bring in water from four 20,000-liter tanker trucks.
In Plan de Hornos, a town in the municipality of Illapel, irrigation technology was installed using reused water instead of drinking water to create a green space for the community to enjoy.
The project included water taps in people’s homes for residents to water trees and flowers.
Arnoldo Olivares, 59, is in charge of the plant, which has 160 members.
“I run both systems,” he told IPS. “I pour drinking water into the pond. After passing through the houses, the water goes into the drainage system, where there is a procedure to reclaim and treat it.”
“This water was lost before, and now we reuse it to irrigate the saplings. We used to work manually, now it is automated. It’s a tremendous change, we’re really happy,” he said.
Antiquera the alfalfa farmer is happy with his success in Cerrillos de Tamaya, but warns that in his area 150 to 160 mm of rainfall per year is normal and so far only 25 mm have fallen in 2023.
“The water crisis forces us to find alternatives and to be 100 percent efficient. Not a drop of water can be wasted. They have forecast very high temperatures for the upcoming (southern hemisphere) summer, which means that plants will require more water in order to thrive,” he said.
Díaz, the sustainability manager of Fundación Chile, said the Coquimbo projects are fully replicable in other water-stressed areas of Chile if a collaborative model is used.
He noted that “in Chile there is no law for the reuse of treated wastewater. There is only a gray water law that was passed years ago, but there are no regulations to implement it.”
He explained, however, that due to the drought, “rural localities today are already reusing wastewater or gray water. This is going to happen, with or without us, with or without a law. The need for water is so great that the communities are accepting the use of treated wastewater.”
The governor of Coquimbo, Krist Naranjo, argued that “a broader vision is needed to value water resources that are essential for life, especially in the context of global climate change.”
“We’re working on different initiatives with different executors, but the essential thing is to value the reuse of graywater recycling,” she told IPS from La Serena, the regional capital.

SRINAGAR, INDIA, Aug 24 (IPS) – Sadiq Dar, 68, is surprised how the heavy siltation of Wular Lake has turned many of its areas into land masses. “When we were growing up, we would only see water in this lake. Now, we see cattle grazing in it while a large portion is also being used by children for playing cricket,” he tells IPS.
Overlooked by magnificent mountains, Wular Lake is one of the largest freshwater lakes in Asia and the largest flood basin of Kashmir in Bandipora district, some 34 km north of Srinagar, the summer capital of Indian Administered Kashmir.
An international Ramsar site under the Ramsar convention, this beautiful lake has served the people of Kashmir for centuries earning praises from all, including its poets.
“How long will they remain hidden from the world … the unique gems that Wular Lake holds in its depth,” 20th century Urdu poet Sir Muhammed Iqbal once wrote about Wular Lake’s depth and water expanse.
Almost a century after Iqbal’s inquisitiveness, the depths of Wular have become heavily silted, its size reduced, and its pristine waters suffer from heavy pollution. This large Himalayan water body and Dal Lake in Srinagar play a key role in flood management, water security and livelihood generation in the region.
But a NASA report recently revealed that both these lakes — Dal Lake and Wular Lake — have witnessed a large reduction in size due to land conversions, urbanization, and deforestation in recent decades. This not only poses a threat of repeated flooding in Kashmir but will negatively influence livelihood generation and the availability of water for the communities.
“The conversion of forests to paved urban areas is a major driver of the change in water quality. Land conversion has delivered heavy sediment and nutrient loads into the lake, and untreated sewage from urban areas has also contributed,” says the NASA report.
“Some of the bright green areas on the eastern side of Wular Lake used to be open water. Nutrient-rich sediment and aquatic vegetation have filled in parts of the lake and contributed to its shrinking in recent decades,” the report further says and adds: “In a 2022 study, researchers in India—using data from the Indian Space Research Organization’s (ISRO) LISS-IV instrument—found that Wular Lake’s open water area had shrunk in size by about one-quarter between 2008 and 2019.”
In a detailed study of the lake, Wetlands International, a Netherlands-based not-for-profit that works to sustain and restore wetlands globally, had also revealed earlier that there was a 45 percent reduction in the lake area mainly because parts of the lake were converted for agriculture and willow tree plantations.
Wular Lake is crucial for saving Kashmir from floods. In recent years, the region has witnessed repeated flood-like situations following the devastating 2014 flooding. The recent IPPCC reports have predicted that there will be an increase in floods and other extreme weather events across South Asia in the coming years as the climate crisis deepens.
The Dal Lake, says the NASA report, has suffered a similar fate in response to land cover change. Researchers in Srinagar found that land conversion to urban development in the basin had worsened the lake’s water quality and contributed to its reduced size, the report says. They found that between 1980 and 2018, the lake shrunk in area by 25 percent, it added.
The marshy and water body area of Dal Lake, a major tourist attraction in Srinagar, has shrunk from 2,547 hectares in 1971 to 1,620 hectares in 2008, another study titled Impact of Urban Land Transformation on Water Bodies found earlier.
How to Stop the Lakes from Shrinking?
Wular Lake and Dal Lake are crucial for the region’s flood management and livelihood generation. Besides acting as a flood absorption basin for Kashmir during high flows in the region’s major river, Jhelum, Wular, and Dal Lake provide livelihood support to over 100,000 families dependent on tourism and fishing, said Samiullah Bhat, senior Assistant Professor at Kashmir University’s Environment and Science department.
To stop further shrinkage of Wular and Dal Lakes, Bhat said that soil erosion in the catchment area of these water bodies, which is resulting in these lakes becoming silted up, must be stopped. “It is because of the massive soil erosion that parts of water bodies are turning into landmasses,” Bhat told IPS.
Regarding encroachments in these lakes, Bhat said that geofencing is one way to mark the boundaries of these lakes, followed by close monitoring. “It has been done recently in the case of Wular Lake, and the same can be done for Dal Lake as well,” Bhat said.
“It is a matter of proper governance, management and effective enforcement of laws for the protection of environmental assets,” he further said, adding that land ownership records and revenue records are also not that transparent, which also need to be addressed for protecting these lakes from further damage.
According to a study, Dal Lake represents a case of a threatened ecosystem in dire need of management, with land use changes, erosion, enhanced nutrient enrichment and rising human population in its catchment as the major threats to its existence.
“Regulation of a proper land use plan in the Dal Lake catchment is vital for preventing the further nutrient enrichment and sedimentation of the lake waters,” the study says.
Aijaz Rasool, an engineer who has worked on these water bodies previously, said that all the areas of Dal Lake and Wular Lake need to be prioritised for complete conservation work. “For years, I have observed that only those areas of the lakes get attention which are visited by tourists, the other sides get least or no attention and keep deteriorating and encroaching. For example, the north-western parts of Dal Lake and Wular,” Rasool said and added that once all the areas of these lakes receive equal conservational treatment, conserving them will get easier.

WASHINGTON DC, Aug 03 (IPS) – The Colorado river basin has recently been wracked by an extended drought which brought to the fore major concerns regarding hydroelectricity production. Up on the Colorado sits the iconic Hoover Dam, which transforms water into enough electricity to power 1.3 million people in Nevada, Arizona and California.
Although an agreement was reached by the three dependent Western states to cut water use, it served as a reminder of the dependency of energy production on water … a dependency that is being subjected to greater uncertainties because of climate change.
This phenomenon is not only impacting citizens dependent on the Colorado River but stretches across the United States and the world. Over the past two years, Europe, China, Brazil, Iraq, the Horn of Africa, have experienced the worst droughts in (sometimes hundreds of) years.
Importantly, the water-to-energy relationship also runs the other way: water production and delivery are themselves dependent on energy.
Moreover, the need of water services for energy is likely to increase, driven by growing populations, rising prosperity (notably in developing countries) and novel uses of energy for water in desalination plants and elsewhere. As we feel the impact of increasingly intense heat waves and droughts, the time has come to revisit the challenges of the water-energy nexus.
The dependence of energy production on water has long been recognized by energy experts, but has surprised many others. Beyond very visible hydropower plants, like the Hoover Dam, water is used to cool down nuclear power plants (through the cooling towers emitting steam that many may have noticed, without perhaps always identifying the purpose), as well as in natural gas and coal-fired plants. Water is also used in various stages of the energy supply chain, including for production and processing.
Climate change is expected, through its impact on water supply and availability, to increase vulnerabilities in energy production. For example, changing rain patterns will create uncertainties for hydropower production, which represents 15 percent of global power generation, even if the overall level of rainfall doesn’t change.
And in a completely different dynamic, various coal power plants dependent on barge transport for resupply have seen their operations imperiled by low water levels. These are aspects that have received some, but altogether inadequate, attention to date.
Both hydroelectricity and nuclear generation, two low-carbon sources of electricity, are expected to increase significantly over decades to come under various government programs to reduce greenhouse gas emissions.
Moreover, even as the need for water to cool down coal-fired plants is eventually expected to drop as countries transition from this carbon intensive fuel source, new uses for water are emerging, including for the production of hydrogen through electrolysis.
What has attracted less attention is the impact of growing demand for energy from developments in water systems. The UN projects that the world’s population will increase by over 1.2 billion by 2040, with about two-thirds of that increase occurring in emerging economies and other developing countries.
These nations are also projected to see significant increases in their income levels, increasing the ability of their populations to access water services, at home, at the office or for pleasure. Moreover, the demand for food is also similarly projected to increase, and with that, the need for more water irrigation services inevitably powered by energy.
These factors are helping to drive an increase in the demand for energy. For example, the International Energy Agency projects that the amount of energy required by the water sector will more than double within 20 years. The major driver under the IEA’s modelling is the demand from desalination plants.
These are no longer confined to the dryer climates of the Middle East and North Africa, but also in regions which once thought that their water supplies were ample, such as Europe or Asia. Other important growing demand for water is also coming from waste water treatment plants and the supply of clean drinking water and sanitation services to both the billions of poor who currently lack it and the other more prosperous billions across the developing world whose consumption is projected to increase.
Unfortunately, efforts to meet this demand will be exacerbated by climate change. For example, droughts are likely to require the transport of water over longer distances to satisfy the needs of populations suffering from water scarcity, an effort that will require more energy.
Similarly, over the past year, droughts have heightened the possibility of water restrictions for millions of people in Southern Europe, including drinking water, which might in turn require more desalination.
But though tensions are inevitable, actions can be taken to, if not avoid the problems, dampen its impact. Actions lie in the water or energy sectors, and, often, at the intersection of the two. In the water sector, these include reducing water losses, allowing construction of rainwater collection tanks for agricultural use, increasing waste-water facilities, and fast-tracking the installation of desalination plants.
The energy-for-water dimension will become increasingly fraught, driven by the combination of climate change, growing populations and increasing prosperity. Not only do we need to redouble our efforts to reduce greenhouse gas emissions, we also require stronger concerted actions on adaptation and resilience.
Like for energy, we need to be more efficient at using water, whether this is for households needs, industrial processes, agriculture or energy; meanwhile concerted action and discussion between those sectors will be needed.
The recent events along the Colorado River serve as an important wake-up call. Water is at the essence of our quality of life, and energy is an integral part of that story. We need to do a better job of managing our thirst for water and the energy required to satisfy that demand … and we need to do this in the face of a changing climate.

SUCHITOTO, El Salvador, Jul 25 (IPS) – A new technology that has arrived in rural villages in El Salvador makes it possible for small farming families to generate biogas with their feces and use it for cooking – something that at first sounded to them like science fiction and also a bit smelly.
In the countryside, composting latrines, which separate urine from feces to produce organic fertilizer, are very popular. But can they really produce gas for cooking?
“It seemed incredible to me,” Marisol Menjívar told IPS as she explained how her biodigester, which is part of a system that includes a toilet and a stove, was installed in the backyard of her house in the village of El Corozal, near Suchitoto, a municipality in the central Salvadoran department of Cuscatlán.
“When the first ones were installed here, I was excited to see that they had stoves hooked up, and I asked if I could have one too,” added Marisol, 48. Hers was installed in March.
El Corozal, population 200, is one of eight rural settlements that make up the Laura López Rural Water and Sanitation Association (Arall), a community organization responsible for providing water to 465 local families.
The families in the small villages, who are dedicated to the cultivation of corn and beans, had to flee the region during the country’s 1980-1992 civil war, due to the fighting.
After the armed conflict, they returned to rebuild their lives and work collectively to provide basic services, especially drinking water, as have many other community organizations, in the absence of government coverage.
In this Central American country of 6.7 million inhabitants, 78.4 percent of rural households have access to piped water, while 10.8 percent are supplied by wells and 10.7 percent by other means.

Since November 2022, the government agency has installed around 500 of these systems free of charge in several villages around the country.
The aim is to enable small farmers to produce sustainable energy, biogas at no cost, which boosts their income and living standards, while at the same time improving the environment.
The program provides each family with a kit that includes a biodigester, a biotoilet, and a small one-burner stove.
In El Corozal, five of these kits were installed by Asa in November 2022, to see if people would accept them or not. To date, 21 have been delivered, and there is a waiting list for more.

“With the first ones were set up, the idea was for people to see how they worked, because there was a lot of ignorance and even fear,” Arall’s president, Enrique Menjívar, told IPS.
In El Corozal there are many families with the surname Menjívar, because of the tradition of close relatives putting down roots in the same place.
“Here we’re almost all related,” Enrique added.
The biodigester is a hermetically sealed polyethylene bag, 2.10 meters long, 1.15 meters wide and 1.30 meters high, inside which bacteria decompose feces or other organic materials.
This process generates biogas, clean energy that is used to fuel the stoves.
The toilets are mounted on a one-meter-high cement slab in latrines in the backyard. They are made of porcelain and have a handle on one side that opens and closes the stool inlet hole.
One of the main advantages that family biodigesters have brought to the inhabitants of El Corozal, a small village in the Salvadoran department of Cuscatlán, is that the whole process begins with clean, hygienic toilets, like this one set up in Marleni Menjívar’s backyard, as opposed to the older dry composting latrines, which drew flies and cockroaches.

They also have a small hand pump, similar to the ones used to inflate bicycle tires, and when the handle is pushed, water is pumped from a bucket to flush the waste down the pipe.
The underground pipe carries the biomass by gravity to the biodigester, located about five meters away.
The system can also be fed with organic waste, by means of a tube with a hole at one end, which must be opened and closed.
Once it has been produced, the biogas is piped through a metal tube to the small stove mounted inside the house.
“I don’t even use matches, I just turn the knob and it lights up,” said Marisol, a homemaker and caregiver. Her husband Manuel Menjívar is a subsistence farmer, and they have a young daughter.
In El Corozal, biodigesters have been installed for families of four or five members, and the equipment generates 300 liters of biogas during the night, enough to use for two hours a day, according to the technical specifications of Coenergy, the company that imports and markets the devices.
But there are also kits that are used by two related families who live next to each other and share the equipment, which includes, in addition to the toilet, a larger biodigester and a two-burner stove.
With more sophisticated equipment, electricity could be generated from biogas produced from landfill waste or farm manure, although this is not yet being done in El Salvador.

Saving money while caring for the environment
The families of El Corozal who have the new latrines and stoves are happy with the results.
What they value the most is saving money by cooking with gas produced by themselves, at no cost.
They used to cook on wood-burning stoves, in the case of food that took longer to make, or on liquefied gas stoves, at a cost of 13 dollars per gas cylinder.
Marleni Menjívar, for example, used two cylinders a month, mainly because of the high level of consumption demanded by the family business of making artisanal cheeses, including a very popular local kind of cottage cheese.
Every day she has to cook 23 liters of whey, the liquid left after milk has been curdled. This consumes the biogas produced overnight.
For meals during the day Marleni still uses the liquefied gas stove, but now she only buys one cylinder a month instead of two, a savings of about 13 dollars per month.
“These savings are important for families here in the countryside,” said Marleni, 28, the mother of a four-year-old girl. The rest of her family is made up of her brother and grandfather.
“We also save water,” she added.
The biotoilet requires only 1.2 liters of water per flush, less than conventional toilets.
In addition, the soils are protected from contamination by septic tank latrines, which are widely used in rural areas, but are leaky and unhygienic.
The new technology avoids these problems.
The liquids resulting from the decomposition process flow through an underground pipe into a pit that functions as a filter, with several layers of gravel and sand. This prevents pollution of the soil and aquifers.
Also, as a by-product of the decomposition process, organic liquid fertilizer is produced for use on crops.
Most families in the rural community of El Corozal have benefited from one-burner stoves that run on biogas produced in family biodigesters. Larger two-burner stoves are also shared by two related families, where they cook on a griddle one of the favorite dishes of Salvadorans: pupusas, corn flour tortillas filled with beans, cheese and pork, among other ingredients.

Checking on site: zero stench
Due to a lack of information, people were initially concerned that if the biogas used in the stoves came from the decomposition of the family’s feces, it would probably stink.
And, worst of all, perhaps the food would also smell.
But little by little these doubts and fears faded away as families saw how the first devices worked.
“That was the first thing they asked, if the gas smelled bad, or if what we were cooking smelled bad,” said Marleni, remembering how the neighbors came to her house to check for themselves when she got the latrine and stove installed in December 2022.
“That was because of the little information that was available, but then we found that this was not the case, our doubts were cleared up and we saw there were no odors,” she added.
She said that, like almost everyone in the village, her family used to have a dry composting toilet, but it stank and generated cockroaches and flies.
“All that has been eliminated, the bathrooms are completely hygienic and clean, and we even had them tiled to make them look nicer,” Marleni said.
She remarked that hygiene is important to her, as her little girl can now go to the bathroom by herself, without worrying about cockroaches and flies.
