Sixty-year-old Bengalata Rout heads for the Casuarina “forest wall” off the shoreline, trees that the women in the 108-household village Tandahara planted after the 1999 Super Cyclonic Storm decimated their mud-walled thatched-roof huts leaving their fertile farms salt-poisoned.

That year, 33 years ago, they planted the trees on the village boundary, a good distance away from the shoreline; today, on a stormy night, the sea crashes against the tree trunks, threatening to run amok into their homes.

Tandahara, sitting on the Bay of Bengal, is one of the last villages in the eastern Indian State Odisha, some 20 kilometres from Konark Sun Temple, UNESCO’s designated heritage site that is itself showing the impacts of seas closing in.

The ‘Big Storm’ Discovery

“When the big cyclone hit us, the Casuarina shelter belt that was standing from before, planted by the government, lay battered,” Rout told Inter Press Service (IPS) as we walked toward the Casuarina forest. “We immediately realised had it not been standing there between the sea and our village we would have been wiped out.”

And it was a life-changing discovery for these rural women.

The category-5 storm, carrying wind speeds of 160 miles hourly that made landfall over Odisha in October 1999, killed more than 10,000 people, mostly owing to 20 ft high storm surges that brought water 16 to 20 miles inland.

But Tandahara had not lost a single life. Losing no time, every woman volunteering, even the children clamouring to pitch in, they sorted themselves into ten groups of ten members with a mix of young and old. Saplings were requested from government and non-profits who came to help. Planting was done; the men lent a hand, but the women took it upon themselves to make sure the saplings survived.

“It was challenging. The soil had salted up, and the young plants struggled to survive,” said Kanaka Behera, 32, one of the younger women. “And the water we got in our village had turned a bit saline also.”

“We thought, for our cooking and drinking, we fetch groundwater from a shallow dug pit; why not get the sweet water for the plants, too? But that was a kilometre inland from our village, more distance from the plantation in the opposite direction. We will do it, we decided and dug the pit wider to get more water,” Behera added.

“For months till the plants survived, we would be up before the sun, lining up our buckets around the water pit where water replenishes naturally overnight. Then the real arduous work began,” said middle-aged Bena Mallika dressed in a bright green sari. Some ten of them would fill the buckets and hand them to ten others who relayed them to more waiting women till the saplings, one-and-half kilometres away, were sloshed and glistening. Only by noon, they were done, exhausted but triumphant, having carried one thousand buckets to the plants. They did this every alternate day. Meticulously, around each baby tree, they gouged a six-inch wide circular channel with their bare hands to hold the sweet water for longer and create an oasis of nutrition.

Climate Events More Frequent, Intense, and the Sea Keeps Getting Closer

But growing tree shields is a daunting exercise against a wounded, intermittently raging ocean. It is a handful of strong-willed women pitted against climate events getting more frequent and more intense from a rapidly warming sea. Odisha has encountered 10 cyclones in a span of 22 years from 1999 to 2021, with frequency rising over earlier decades, according to data from the Odisha State Disaster Management Authority (OSDMA), which works to reduce disaster risk.

More broadly, the Indian subcontinent has witnessed more than 478 extreme events since 1970, whose frequency has accelerated after 2005, IPS had earlier reported.

But another phenomenon, more insidiously devastating, is creeping in on Tandahara.

Sitting on a cemented platform under the shade of an ageing banyan tree, there are several elders who share how the sea has moved closer. Remembering over five decades back, 70-year-old Tahali Kalia Gopal Behera narrated to IPS, “When I was 18, we youngsters went to the sea to catch the red beach crabs. We carried our lunch and left home in the morning, returning only in the evening. Those days, the sea was more than 3 kilometres away.”

“The sea has eaten away 20 hectares of our village land,” Bidyadhar Bhuyan, another elderly man, said.

Of Odisha State’s over the 480-kilometre coastline, a high 79 percent has experienced drastic modification.

The State’s coastline change trend shows 21 percent has been subject to erosion, and 51 percent is impacted by accretion. Based on 26 years of satellite images, the 2018 study by the National Centre for Coastal Research of Earth Sciences Ministry remains the latest using such extensive data.

Odisha’s Puri province, where sea-front villages like Tandahara face the brunt, experienced the highest accretion on 110 km of its total 140 km shore length, this study said.

Coastal accretion is the gradual increase or acquisition of land by the sea. It occurs through washing up sand, soil, or silt. Erosion is the gradual washing away of land along the shoreline.

While erosion-accretion phenomena are natural, climate disasters and persisting low-pressure events that cause turbulent seas are increasing ecological imbalance, according to an OSDMA expert.

“When I married and came to the village, there were sand dunes stretching all the way,” remembered 46-year-old Mallika. “Now there’s hardly any beach left for dunes to stand; only the shore sands are rising higher.”

So close is the sea now that this year, 2023, even without any major low-pressure event, sea-water ingress has cut a 100-metre channel into pastureland on the village outskirt, Bhuyan added.

Oxford University research from across 52 sites worldwide on ‘nature-based solutions’ said coastal forest walls, mangroves and coral reefs cause waves to break before they hit the shore or ingress towards human habitats, lowering both the force and height of the swell and in the process reducing the likelihood of the sea breaching over into people’s land.

The study found that natural habitats were 2-5 times more cost-effective than engineered structures, like the geotextile tube installed in another affected district in Odisha, which was in tatters within 10 years. These (like Tandahara’s bio-wall) can help to protect from climate change impacts while slowing further warming (by carbon sequestration), supporting biodiversity, and securing ecosystem services, researchers widely believe.

Of Bulls, Goats and Other Challenges

As the Bay of Bengal became a hotspot for tropical storms and waves inched closer to Tandahara, coating salty mist day and night on everything, their staple rice crops began failing. Employable males migrated out.

Left behind with children and ageing parents to make ends meet were again the women. They began goat-keeping. The 108 households have no less than 500 goats today.

One adult goat weighing 15kg can easily fetch up to INR 8000 (USD 96.3), extra during festive seasons.

Handsome returns, yes, but also the biggest daily menace to women’s Casuarina walls.

“Until saplings are at least 5 feet tall and out of reach of the ever-hungry goats, we need to protect them. We patrol in groups of three, morning and afternoon,” elderly Harkamani Swain said.

Rout walks on purposefully; it’s difficult to keep up with her, traversing over uneven abandoned paddy fields. She is going to check if any goats or the village bull have walked in to nibble at the new saplings planted under the government’s forestry scheme earlier in August this year when rains came.

If she espies the bull amidst the plants, she’ll holler, and the women will rush and help chase it out.

“If cattle destroy the plants, their owners have to pay a 100 rupees (USD 1.2) penalty, Rout explains, sighing in relief on seeing no intruder. “To get a hungry bull off the plantation requires more than one woman. If a help call is shouted out, but the group member whose house is closest does not respond, they are charged 100 rupees as well,” she explains how strict community rules have helped them grow the tree wall.

Seeing their zeal, in 2000, the forestry officials mentored them to form a village Forest Protection Committee. They were provided, one-time and free of cost, several large party-sized ironware pots worth 60,000 rupees (USD 722.8) to rent out to village events and maintain bank funds.

“Were this active group not been looking after the coastal forest, even when the government plants and sometimes waters them too, they would not remain alive beyond a month. There is a strong sense of ownership instilled within them. With them, we have a true partnership,” a local supervisory-level government forest official told IPS, wishing not to be named as they were not allowed to speak to the media.

Green Walls Provide Direct and Indirect Income for an Entire Village

When forest officials came with saplings this monsoon, the nearby beach was littered with dead Casuarina stumps and branches left from an earlier storm and proliferating beach creepers. The women’s group offered to clear the large stretches. In return, they got to take home the dead wood.

“With the thinner branches, we were able to repair seaside fences,” Kanaka Behera told IPS. The official would otherwise have hired contractors’ men on wages. “We take ownership of the storm walls. We will patrol till the saplings are grown.”

Dead trees get used for roof beams of thatched cattle sheds and for firewood, fulfilling needs in rural households. Odisha government, since the 2013 Phailin storm, has provided concrete-roofed, brick-walled disaster-resilient houses within 5 km of high tide.

Under the thick canopy of Casuarinas, a rotting pile of hay lies in a corner. The women can grow two mushroom crops here from early July to late August. The dense thicket obstructs damaging rain directly falling on the delicate fungi; high humidity is just right for bountiful harvests, which income goes into the group’s bank account, used when members need funds urgently.

Rout points further afield at over 25 green net-cloth-covered betel vine bowers just behind the Casuarina thicket. The 8-feet high square bamboo bowers, locally called ‘bareja’, are shading structures creating a green-house environment for better quality betel leaves. It can fetch a good income but is a fragile cultivation. “Those ‘barejas’ stand because this thick line of Casuarinas stands against strong winds that can easily bring the structures down and deprive a quarter of our village households of their livelihood,” she said.

Most afternoons, with household chores and afternoon meals done, the women leave the village behind to sit in the quiet under the trees. Sometimes, they laugh together, sing even if tunelessly, as the birds call from the branches, used to their presence.

“These trees are today like our grown-up sons; they stand strong here, ready to protect us, giving us confidence and moments of contentment,” says the elderly Bengalata Rout, whose only son Ritu, 40 years old, is working as a computer clerk thousands of kilometres away in Surat in western India, holding on to a deeply grooved tree trunk. A widow, she lives with her daughter-in-law and two little grandsons.

Powerful Agents of Change United in Fighting More Than Just the Storms and Seas

The water from the borewells in Tandahara became progressively so salty that children, no matter how thirsty, would often refuse to drink. Water carried from the small groundwater pit never sufficed. Forced to drink increasingly salty water, stomach upset, nausea and skin irritation have become chronic.

Bonding together for the tree barrier has, over the years, given the women of Tandahara a sense of unity and empowerment, and they are changing the collective traditional mindset of the village as well.

Post-pandemic, taking the poor drinking water issue into their own hands, the traditionally village-bound women marched to the local-level government officer with bottles of the salty water they got from hand pumps and asked the officer to drink it. The officer was shocked at the confrontation from a group of village women but finally admitted the water was undrinkable and ordered water tankers to deliver to the village.

Water is, however, supplied only in April and May, peak summer months when local water turns saltier. Again, it is limited to daily just two buckets per household, even for large families. On repeated visits by the women, administration higher-ups even visited the village five months back, promised piped water, but work is yet to begin, said 29-year-old Gouri Padhi, who has been in school up to class ten and is more educated than the others.

Looking Ahead

“Communities already have the agency to adapt and make decisions in the face of change,” said the Global Resilience Partnership Report 2023, but often need support in the form of appropriate data, knowledge, information, and resources to further strengthen adaptation and resilience actions.

“As climate and other shocks become more frequent, severe and overlapping, it is urgent to become smarter and faster when it comes to building resilience,” Dina Esposito, Assistant to the Administrator for the Bureau for Resilience and Food Security, told IPS via email. “At USAID, we’re bringing innovative solutions, such as shock response monitoring systems, to build resilience and to measure impact so that we can learn and adapt as we go.”

For the women of Tandahara, resilience is found in their collective efforts to save their village.

While murmurs are growing stronger among elderly men to step back from the advancing sea and resettle their homes at a safe distance. Two neighbouring villages have already left, illegally squatting on forest land, they point out.

“True, whenever the winds wail, my heart palpitates with dread; I think today all will end. When the government mobile alerts shriek, we flee to the two-storied storm shelter with our cattle. But we will not abandon our ancestral village,” Rout says firmly. “We will do whatever it takes to make it safer, but we will not leave,” she echoes her group’s stand on this crucial issue. Many of the younger generation youth listening nod in agreement.

Climate Change Colludes with Bad Development — Global Issues

Monsoon rains flooding Indian cities is more widespread in 2023, raising questions on business-as-usual development policies that continue even as climate conspicuously shifts. CREDIT: Manipadma Jena/IPS

  • Inter Press Service

Himachal Pradesh received 250 millimetres or ten inches of rain in just four days, between 7 to 11 July, which accounted for almost 30 percent of the total monsoon rainfall in a year. This sent mountain rivers spilling over their banks into villages and towns and caused widespread flash flooding, mud, and landslides.

Over the whole month of July, the State received 71 percent excess of 438 mm actual rainfall against 255.9 mm normal rainfall. It is the second-highest rainfall in 43 years, since 1980, according to the government’s meteorological department.

Himachal Pradesh has witnessed a six-time increase in major landslides in the past two years, with 117 occurring in 2022 as compared to 16 in 2020, according to data compiled by the State disaster management department.

This year until now, the state witnessed 79 landslides and 53 flash flood incidents, with the monsoon only halfway, arriving in late June, as per the developing data.

There have been 223 deaths from these disasters to date. Cloudbursts and losses continue in Himachal Pradesh. Even on August 10, a family of 5 were buried under their collapsed home.

Is Faulty Ecological Development Worsening the Damage?

A video that has gone viral worldwide sums up not just the magnitude of destruction but answers some of the reasons why. The video opens with loud panic calls as a thickened river of muck and huge logs swerve downhill monstrously into a narrow village lane flanked by rows of shops in Thunag village in the Mandi district of Himachal Pradesh.

Locals claimed the trees are Himalayan Cedars chopped down in tens of thousands to widen highways as the government rapidly develops its mid-hills as go-to summer holiday destinations for tourism.

Trees from forest land cleared for roads, tunnels and hydro-power dams are disposed on hill slopes, in rivers banks and streams along with the earthen muck and debris, said Tikender Singh Panwar, a city administrator who had earlier held office.

The course of the rivers has narrowed down, and the riverbeds filled up with silt, causing them to break banks much sooner than they normally would when torrential rains come.

Both tourism and hydro-electricity sectors are the highest earners for the government and are currently being developed on priority.

The planned development is responsible for this colossal damage, is not so much climate shift, Panwar categorically says. An urban specialist and earlier deputy mayor of Shimla, the State’s summer capital, Panwar, says the focus of Himachal Pradesh, with a fragile Himalayan ecosystem, is on (risky) exploitation of natural resources of water, forest, and nature to pull in more State income.

Traditionally, mountain regions for building infrastructure were not cut with vertical slits but terraced to minimise instability in these geologically vulnerable regions. Unfortunately, in a hurry to complete projects, mountains have been cut into vertically, leading to landslides, according to Panwar.

The government’s Himachal Pradesh State Disaster Management Authority agrees. “Vulnerability of the geologically young and not-so-stable steep slopes in various Himalayan ranges has been increasing at a rapid rate in the recent decade due to inappropriate human activity like deforestation, road cutting, terracing and changes in agriculture crops requiring more intense watering.”

Land use change is another trigger being viewed as causing a natural disaster to become more damaging. Spreading concrete infrastructures, including “river-view” hotels and homestays, encroach on the riverbanks and basins.

Cement plants have proliferated to meet the demand for leap-frogging constructions.

When more rainfall lands in an area than the ground can absorb, or it falls in areas with a lot of impermeable surfaces like concrete and road asphalt that prevent absorption, the water runs downhill, gathering force and everything on its way, turning streams and rivers into raging torrents. It seeks the lowest point in a potential pathway, often reclaiming its own encroached space – the river basin.

In India’s mostly unplanned urban areas, these often are roads, parking lots, slum settlements, and even multi-storied shops and homes. Changes in land use and land cover contribute to acerbate disaster damage.

Sand mined illegally from riverbanks to keep pace with the high demand from construction activities could also have played a role in the devastation that rivers caused in Himachal Pradesh, environmental activists said.

Question Mark on Hydro-Power Projects in Fragile Himalayan Region

Hydropower is the biggest source of income for Himachal Pradesh, with the national government having a major stake. The State has five major rivers. It sells electricity to other states. Rural electrification, too, remains a major focus. But the environmental cost of the dams in the Himalayan region may be high and already being experienced, said activists.

The State’s hydroelectricity potential is high, around 27,436 megawatts, which is 25 percent of the national potential. Of this, 10,519 MW is harnessed so far. More projects with lengthy tunnels to channelise river flow are being added quickly. “Sometimes the course of rivers was diverted to build dams for hydro-power projects. This is like playing with nature, says Panwar.

By 2030, some 1088 hydropower projects are planned to generate 22640 MW of electricity, according to Panwar. India has committed to achieving 500 Gigawatts of renewable energy by 2030.

This is raising alarm bells for more impending disasters.

In a Warming Asia: The Role of Climate Change in Increasing Water Disasters

When the cloudburst in the Thunag area dumped torrential rains, locals said they had no warning. But cloudbursts are characteristically localised, and sudden torrential rainstorm phenomena, categorised when rainfall is 100 millimetres per hour, have been increasing.

Cloudbursts occur when warm air currents block rain from falling, causing an accumulation of moisture. When the upward air currents become weak, the cloud dumps rain.

Flash flooding similarly occurs after excessive rainfall pours down in less than six hours. Both are unexpected and often catch victims unprepared.

The role of climate change is becoming increasingly evident in these types of deluges across continents.

The simplest part of the explanation for a complex phenomenon is that warmer temperatures lead to increased evaporation. This leads to extra moisture in the atmosphere, which in turn leads to heavy rainfall, especially when two weather systems coincide in a high-altitude, mountainous region. This is what happened in Himachal Pradesh in early July.

A low-pressure weather system carrying moisture all the way from the Mediterranean Sea to northern India, known as a Western Disturbance, coincided with the normal monsoon system, together resulting in torrential rain. This is not abnormal and, as such, not attributable to changing climate.

However, studies by scientists around the world show that the climate shift is intensifying the water cycle and will continue to intensify as the planet warms. A number of factors are intensifying the water cycle, but one of the most important is that warming temperatures raise the upper limit on the amount of moisture in the air. That increases the potential for more rain.

An international climate assessment in 2021 documented an increase in both wet extremes, including more intense rainfall over most regions, and dry extremes. These will continue to increase with future warming.

In India’s Himalayan region, with its complex terrain and varied weather patterns, deep, intense convective clouds form under normal circumstances. However, studies find instances of deep convection have increased over recent years. Sixty-five percent area in the Himalayan States now shows a trend towards ‘daily extreme rainfall’ categorised when 15 cm of rain falls in 24 hours. Climate change is thought to be one of the main causes of this, according to Madhavan Rajeevan, a senior retired official of India’s Ministry of Earth Sciences. “This can have severe consequences,” he says.

According to the International Disaster Database (EM-DAT), Asia is the world’s most disaster-impacted region; 83 percent of the 81 weather, climate, and water-related disasters in Asia in 2022 were flood and storm events. More than 50 million people were directly affected.

WMO State of the Climate in Asia 2022 report released in July said Asia, the largest continent with 30 percent of Earth’s land area, is warming faster than the global average. The warming trend in Asia in 1991–2022 was almost double the warming trend in the 1961–1990 period (see chart), according to the World Meteorological Organisation report.

IPBES to Release New Assessments on the Values of Biodiversity and Sustainable Use of Wild Species — Global Issues

  • Inter Press Service

Larigauderie said it was crucial to provide resources and build capacity in under-resourced developing countries where much of the remaining biodiversity is located. Financial resources were particularly needed, she said, to fund global biodiversity observing systems in order to monitor biodiversity in order to follow progress according to internationally agreed indicators and targets. She was speaking to IPS ahead of the ninth session of the IPBES Plenary (#IPBES9) in Bonn, Germany.

IPBES harnesses the best expertise from across a wide range of scientific disciplines and knowledge communities to provide policy-relevant evidence and knowledge, thus helping to catalyse the implementation of knowledge-based policies at all levels of government, the private sector and civil society.

In the face of the worsening climate crisis and rapid biodiversity loss, IPBES’ role has been growing in importance since it was established in 2012.

IPBES’ first thematic assessment, on Pollinators, Pollination and Food Production (2016) brought a global focus to issues relating to the protection and importance of all pollinators, and has since resulted in a number of strong policy changes and actions globally, nationally and locally.

At #IPBES9, 139 member governments are expected to approve two crucial new scientific assessment reports, one regarding the sustainable use of wild species and the other regarding nature’s diverse values and valuation.

Four years in development, the ‘Sustainable Use Assessment’ has been written by 85 leading experts, drawing on more than 6,200 references, while the ‘Values Assessment’ has 82 top expert authors, drawing on more than 13,000 references.

Excerpts of the interview follow:

Inter Press Service (IPS): IPBES provides policy-relevant knowledge to catalyse the implementation of policies at all levels, including awareness-raising among the public. What outcome do you expect from #IPBES9? 

Anne Larigauderie (AL): We expect to have three major outcomes. Two new reports will be submitted for approval and are planned for release from #IPBES9. One is on the values and valuation of nature and the other is on the sustainable use of wild species. A third major outcome of the meeting is expected to be a decision about starting a new report on business and biodiversity, which would be produced in a couple of years.

IPS: How significant are these new reports’ findings for biodiversity conservation in particular, and more broadly for achieving a range of biodiversity-related SDGs, including food security and climate change? You have mentioned elsewhere that climate science may be working in a silo and not, ideally, together with biodiversity goals. How are IPBES scientific data-based reports helping bring working synergy to these critically interlinked SDGs?

AL: You really put your finger on a very major issue and message that IPBES has been trying to advance.

One of the key conclusions of the IPBES Global Assessment on Biodiversity and Ecosystem Services was that with the current loss of biodiversity and degradation of nature, we are not going to achieve the two most directly biodiversity-related SDGs: 14 and 15. We will also miss a number of the other goals related to the production of food, water quality, health and climate change.

With the ongoing overuse of pesticides, loss in soil biodiversity and in pollinators, among others, we will for example not be able to reach SDG-2 on zero hunger.

With current high rates of deforestation, land degradation, and the overuse of fertilisers, we also cannot reach SDG-13 – to take urgent action to combat climate change and its impacts – because all of the actions that I just described, are either contributing to greenhouse gas emissions or reducing the capacity of natural ecosystems to mitigate against climate change.

Deforestation also threatens SDG-3 related to good health. So, protecting biodiversity is not only necessary for conserving nature, but it also really is about reaching all of those other key SDGs and protecting all of nature’s other contributions to people as well.

IPS: How can IPBES ensure wild species, hugely important but still largely under-appreciated, are sustainably used?

AL: Based on the latest scientific data, IPBES assessments inform decision-making. Then it is up to governments and a diverse set of actors to act.

IPBES’ 2016 report on the status of pollinators and the impact on food security has informed quite a lot of new legislation around the world. It triggered a new UN Food and Agriculture (FAO) international initiative on pollinators, for instance. All this contributes to reducing the loss of pollinators. We hope for a similar level of impact from the report on the sustainable use of wild species once it has been released.

IPS: How effectively and urgently are countries implementing the IPBES-informed policies that would result in much-needed transformative changes for reaching biodiversity targets?

AL: Clearly, not enough. The IPBES Global Assessment of Biodiversity and Ecosystem Services concluded in 2019, that good progress had been achieved towards components of only four out of the 20 Aichi Biodiversity Targets of the Convention on Biological Diversity (CBD) to be achieved by 2020. Because of the pandemic, the 15th session of the Conference of the Parties to the Convention on Biological Diversity (COP15), initially scheduled for 2020 has been rescheduled for December 2022. This is of course having an impact on many policies, which are related to the global agenda, including at the national level.

IPS: What kinds of things would the IPBES scientific community think are still needed globally to enable much greater information flow, robust databases and wider involvement of the scientific community?

AL: What we do not have currently for biodiversity is a global biodiversity observing system. The climate change community has had a Global Climate Observing System ever since the Climate Change Convention started.

As part of this system, governments have agreed on a set of essential climate variables (for example, water temperature or salinity) which are measured by all governments thanks to in-situ and remotely sensed capacity, and shared in common databases, thus enabling scientists to project future trends in climate change, among others.

For biodiversity, there is no such global observing system agreed upon and funded by governments, with the proper capacity to monitor changes in biodiversity and thus know if policy implementation has succeeded or failed.

Currently, biodiversity data are collected according to different protocols, stored in separate databases, with many gaps (for example, taxa, geographic, temporal) and no operational capacity, such as dedicated agencies, to ensure the long-term collection and proper storage of data. These gaps are particularly important in developing countries, where much biodiversity lies.

We can formulate the hope that COP15 will emphasise the need for a proper intergovernmental global biodiversity observing system and pave the way for a mechanism to properly resource such a system.

IPS: Is data collection focusing more on flagship species and not enough on other species which may not be as ‘glamorous’ but are critical for healthy ecosystems?

AL: There is definitely a general bias in data collection. Over the years, particularly in the past, people have focused their efforts on the animals they saw, liked, found attractive or interesting – think about birds, which are the most observed animals in the world because they have always fascinated people. That bias is changing, however, as new technologies provide access to environments which were too small or too difficult to reach. Studying soil microflora and microfauna or deep ocean biodiversity is becoming possible, but many of these techniques remain expensive and thus require funds and capacity building.

IPS: Are countries doing enough to preserve and promote indigenous knowledge of biodiversity?

AL: IPBES has placed a major emphasis on indigenous knowledge in its work. It was one of our guiding principles right when IPBES started. The choice was made by governments to not only rely on scientific knowledge in our reports but also on knowledge from indigenous peoples and local communities. Over the years, IPBES has invested quite a lot in developing an inclusive approach and engaging more closely with indigenous communities.

This has made the IPBES reports richer, more diverse, and more relevant to everyone, including indigenous people, who have often managed to keep their environment in better shape than others – even though their territories are threatened by climate change and other issues for which they are often not responsible.

So yes, this is an area that IPBES strongly supports and values. IPBES has actually played quite an innovative role, and inspired others with its unique approach, including the climate change community.

IPS: Can you share with our readers some clues about future IPBES assessments?

AL: We are finishing a report on invasive alien species and their control, that is planned for launch next year and then we have two new reports that are already in progress. One is on the nexus between biodiversity, water, food and health. Here IPBES is looking at how to simultaneously achieve the Sustainable Development Goals related to food, water, and health and also touching upon climate and energy together with biodiversity and ecosystems. We want to really get out of the silo approach and inform people about the options that are available to reach these goals simultaneously and not one at the expense of the other.

The other assessment is on transformative change– where IPBES is exploring the type of values and behaviours which are the origin of the indirect and direct drivers of biodiversity loss, and how they could be transformed. These underlying causes of biodiversity loss are difficult to study and often neglected but they are the root causes of all the issues and need to be better understood to be properly addressed.
