Northeast (NE) India is more than just a region on the map; it is a treasure trove of beautiful
natural landscapes and ecological wealth that plays an essential role in our planet’s health. As
we celebrate World Environment Day 2024 with the theme of restoration, let us highlight the
ecological richness of Assam and the other Northeastern states of India. From the slopes of
Arunachal Pradesh to the lowlands of Assam, the NE region is a biodiversity hotspot, home to
unique species found nowhere else on Earth. The more we explore this ecological richness,
the more we discover the wonders and mysteries it holds, sparking our curiosity and interest.

The scenic landscapes of the NE region exemplify a dynamic and harmonious relationship
between humans and nature. Indigenous communities here have cultivated a profound
repository of traditional ecological knowledge passed down through generations. The Bodos,
Mishings, Karbis, Nyishis, Angamis, Khasis, and many others have developed a deep-rooted
understanding of their natural surroundings through intimate interactions with forests, rivers,
and mountains.

One of the most remarkable aspects of this traditional wisdom is the extensive knowledge of
local plants and their uses. These communities have identified and utilized numerous plant
species for food, medicine, shelter, and rituals, demonstrating a profound understanding of
the ecological roles of each species. For instance, the Bodos have long made use of medicinal
plants like Bhut Jolokia (ghost chili) for their therapeutic properties, contributing to the
preservation of traditional healing practices. This knowledge not only highlights the ecological
and cultural diversity of the region but also supports sustainable development and
conservation efforts.

Beyond plant knowledge, these communities have developed sophisticated ecosystem
management practices. Indigenous forest management practices in NE India have
significantly contributed to maintaining biodiversity hotspots and preserving wildlife habitats.
Traditional agroforestry systems, such as jhum cultivation practiced by the Karbi and Khasi
tribes, have shown resilience to climate variability while supporting local livelihoods. According
to a recent United Nations report, indigenous peoples’ territories encompass about 80% of the
world’s remaining biodiversity, underscoring the importance of their stewardship in
conservation efforts.

The wisdom of the hills and valleys also embodies resilience—a capacity to adapt and thrive
amidst changing circumstances. Indigenous communities have overcome challenges like
floods, droughts, and shifting climates by drawing on their deep ecological knowledge.

According to the Indian State Forest Report 2021, Assam’s forest cover is around 35% of its
geographical area, highlighting its critical role in biodiversity conservation and carbon
sequestration. However, this forest cover is declining, and the region faces environmental and
climate challenges, including deforestation, riverbank erosion, and climate change impacts.

Preserving and promoting traditional ecological knowledge is crucial in the face of the global
climate crisis. According to UNESCO, indigenous communities’ traditional knowledge
significantly contributes to the sustainable management of natural resources, benefiting both
local communities and global biodiversity. Recognizing, valuing, and supporting these
practices are essential for environmental conservation, cultural identity, and community
resilience.

Celebrating the wisdom of Assam and Northeast India’s hills and valleys on World
Environment Day reminds us of the transformative power of indigenous knowledge.
Integrating their insights into broader restoration efforts can contribute to building a sustainable
future for all. By embracing the wisdom passed down through generations and augmenting it
with contemporary research and statistics, we, the #GenerationRestoration, can pave the way
toward ecological harmony and resilience in the years to come.

Let us change gears to the tea communities of the NE region. Assam also plays a vital role in
India’s tea production, boasting over 312 210 hectares of tea cultivation. These tea plantations
not only fuel the state’s economy but also hold significant cultural and ecological value. Assam
is among the world’s largest tea-producing regions, with an annual production of 500-700
million kilograms (Mkgs) of tea leaves. The tea industry employs a vast workforce and
supports livelihoods throughout the region, contributing significantly to India’s overall tea
production. The tea plantations in Assam are not only unique but also serve as a prime
example of the harmonious blend of agriculture and biodiversity conservation. The lush green
tea bushes are seamlessly intertwined with shade trees, providing a habitat for various birds
and insects. Assam’s tea is globally renowned for its robust flavor and represents a heritage
deeply rooted in the land and its ecosystems. However, climate and environmental changes
threaten these lush industries, impacting the ecological and socio-economic balance in the
region.

The government has launched several key initiatives to promote development, ecological
conservation, and socio-economic growth across the state. Notable initiatives include the
Assam Budget for Sustainable Development, Assam Tea Tribes Welfare Board, Jal Jeevan
Mission (Har Ghar Jal), Assam Arunodoi Scheme, Assam Green Mission, Assam Skill
Development Mission, and Assam Startup. Effective implementation of these programs aims
to address climate change, promote environmental conservation, and improve the overall
quality of life for the people of Assam. However, the success of these programs depends on
thorough execution at the grassroots level.

What unfolds in the remote corners of Assam reverberates across continents. The lessons
gleaned from this region—on biodiversity conservation, traditional knowledge integration, and
community-led resilience—are universal. They inform global discussions on sustainable
development, emphasizing the need for inclusive approaches that prioritize both people and
the planet.

This World Environment Day, let us heed the call of Northeast India—a call to action for
environmental engagement and climate action involving youth, communities, government
agencies, and non-profit organizations. The region’s youth must understand the challenges
facing their environment and take action to safeguard their communities and natural
surroundings amidst infrastructural growth and development for their own and future
generations. Climate mitigation and adaptation strategies tailored to the region’s unique
context are critical, including afforestation, sustainable agriculture, and flood management
solutions. Youth can lead the way in developing context-specific climate adaptation and
environment restoration strategies that respect local cultures and ecosystems. By immersing
themselves in environmental education, research, and activism, young students can amplify
their voices and influence decision-makers at all levels.

Assam and its neighboring states in India stand out as a distinctive and valuable addition to
the mosaic of Earth’s landscapes. They serve as a beacon of hope and possibility in our
collective journey toward planetary stewardship. The region’s unique natural heritage,
combined with its rich cultural and ethnic diversity, makes it an important site for scientific
research and cultural exchange. As we strive to better understand and protect our planet,
regions like Northeast India offer invaluable insights and opportunities for collaboration.

India heatwave: why the region should prepare for even more extreme heat in the near future

An extreme heatwave in India and Pakistan has left more than a billion people in one of the most densely populated parts of the world facing temperatures well above 40℃. Although this has not broken all-time records for the regions, the hottest part of the year is yet to come.

Though the heatwave is already testing people’s ability to survive, and has led to crop failures and power blackouts, the really scary thing is that it could be worse: based on what has happened elsewhere at some point India is “due” an even more intense heatwave.

Together with a few other climate scientists, we recently looked for the most extreme heatwaves globally over the past 60 years – based on the greatest difference from expected temperature variability in that area, rather than by maximum heat alone. India and Pakistan do not feature in our results, now published in the journal Science Advances. Despite regularly having extremely high temperatures and levels of heat stress in absolute terms, when defined in terms of deviation from the local normal, heatwaves in India and Pakistan to date have not been all that extreme.

In fact, we highlighted India as a region with a particularly low greatest historical extreme. In the data we assessed, we didn’t find any heatwaves in India or Pakistan outside three standard deviations from the mean, when statistically such an event would be expected once every 30 or so years. The most severe heatwave we identified, in southeast Asia in 1998, was five standard deviations from the mean. An equivalent outlier heatwave in India today would mean temperatures of over 50℃ across large swaths of the country – such temperatures have only been seen at localised points so far.

Our work therefore suggests India may experience even more extreme heat. Assuming the statistical distribution of daily maximum temperatures is broadly the same across the world, statistically a record-breaking heatwave is likely to occur in India at some point. The region has not yet had reason to adapt to such temperatures, so may be particularly vulnerable.

Harvests and health

Although the current heatwave has not broken any all-time records, it is still exceptional. Many parts of India have experienced their hottest April on record. Such heat this early in the year will have devastating impacts on crops in a region where many rely on the wheat harvest both to eat and to earn a living. Usually, extreme heat in this area is closely followed by cooling monsoons – but these are still months away.

It is not just crop harvests that will bear the brunt, as heatwaves affect infrastructure, ecosystems and human health. The impacts on human health are complex as both meteorological factors (how hot and humid it is) and socioeconomic factors (how people live and how they are able to adapt) come into play. We do know that heat stress can lead to long-term health issues such as cardiovascular diseases, kidney failure, respiratory distress and liver failure, though we will be unable to know exactly how many people will die in this heatwave due to the lack of necessary health data from India and Pakistan.

What the future holds

To consider the impact of extreme heat over the next few decades, we have to look at both climate change and population growth, since it is a combination of the two that will amplify the human-health impacts of heat extremes in the Indian subcontinent.

In our new study, we investigated how extremes are projected to increase in the future. We used a large ensemble of climate model simulations, which gave us many times more data than is available for the real world. We found that the statistical distribution of extremes, relative to a shift in the underlying climate as it generally gets warmer, does not change. In the climate models the daily temperature extremes increase at the same rate as the shift in the mean climate. The IPCC’s latest report stated that heat waves will become more intense and more frequent in south Asia this century. Our results support this.

The current heatwave is affecting over 1.5 billion people and over the next 50 years the population of the Indian subcontinent is projected to increase by a further 30%. That means hundreds of millions more people will be born into a region that is likely to experience more frequent and more severe heatwaves. With even larger numbers of people being affected by even greater heat extremes in the future, measures to adapt to climate change must be accelerated – urgently.The Conversation

Indian farmers’ strike continues in the shadow of COVID-19

In what is believed to be the biggest protest in history, in late November 2020 farmers from across India drove 200,000 trolleys and tractors towards Delhi’s borders in a mass protest against agricultural reforms. This was followed a few days later by a general strike involving 250 million people in both urban and rural areas of India as workers joined together to support the farmers.

The strike continues, despite the global public health crisis, which is hitting India harder than any other country in the world. Fear of COVID-19 has not deterred farmers, who have emphatically stated that regardless of whether they contract the virus, the “black laws” will kill them anyway.

The movement first began in the state of Punjab in June 2020, as farmers blocked freight railway lines in protest against these “black laws”, which increase corporate control over all aspects of the food chain from seed to sale. Farmers unions argue that the laws undermine state-controlled prices of key crops, by allowing sales outside of state mandis (markets).

The laws also enable corporations to control what contract farmers grow and how, thus reducing the bargaining power of small farmers. Corporations will be allowed to stockpile key produce and hence speculate with food, which was previously illegal. Finally, the laws provide legal immunity to corporations operating in “good faith”, thereby voiding the ability of citizens to hold agribusiness to account.

Braving tear gas and water cannons, thousands of farmers and their families descended on Delhi and transformed its busy roads into bustling camp cities, with communal “langhar” kitchens.

Undeterred by police violence, farmers fed these aggressors who beat them by day with free food by night. This act of community service not only underscored the peaceful intentions of the protests but also encapsulated one of the key ideas of the movement: “no farmers, no food”.

In the same spirit of solidarity, farmers at Delhi’s borders are responding to the rapidly escalating spread of COVID-19 in the city. They are distributing food packages and essential goods to hospitals, as well as in bus and railway stations for those leaving the capital.

Farmers from numerous states, of all castes and religions, are coexisting and growing the protest movement from the soil upwards – literally, turning trenches into vegetable gardens. Many farmers refer to this movement as “andolan” – a revolution – where alliances are being forged between landless farm labourers and smallholder farmers. In a country deeply divided by caste and – increasingly – religion, this coming together around land, soil and food has powerful potential.

Women have also taken leading roles, as they push for recognition as farmers in their own right. They are exploring the intersections of caste oppression, gendered labour and sexual violence in person and in publications such as Karti Dharti – a women-led magazine sharing stories and voices from the movement.

Violent response

Despite the largely peaceful protests, farmers have been met with state repression and violence. At various points water supplies have been cut to the protest sites and internet services blocked. Undeterred, farmers have prepared the camp sites for the scorching summer heat that now envelops them.

Amnesty international has called on the Indian government to “stop escalating crackdown on protesters, farm leaders and journalists”. Eight media workers have been charged with sedition, while 100 people protesters have disappeared. In response, parliaments around the world have issued statements and debates on the right to peaceful protest in India, as well as a free and open press.

The heavy-handed government response and intransigence to the key demands of the movement adds grave doubt for farmers who are now being asked to disband protest sites in the interest of public health. It highlights the hypocrisy of being told to go home, while the ruling BJP was holding mass rallies in West Bengal.

The fear is that COVID-19 could derail the momentum of this movement, as with the protests around the Citizen Amendment Act, which were cleared in March 2020 due to enforced lockdown to curb the spread of COVID-19. Farmers repeat that they will leave as soon as the government repeals the laws and protects the minimum support price of key crops.

There has been a groundswell of support from around the globe, from peasant movements, the Indian diaspora community and celebrities – including Rihanna and climate activist Greta Thunberg. This movement is fighting for the principles of democracy on which the Indian state was founded and is part of a civil society movement filling in for the state, which has been found sorely wanting in its response to the calamitous consequences of COVID-19.

The “black laws” are but the latest in a long history of struggle faced by Indian farmers. India’s sprawling fields have been sites of “green revolution” experimentation since the 1960s. This has worsened water scarcity, reduced crop genetic diversity, damaged biodiversity, eroded and depleted soils, all of which has reduced soil fertility.

The financial burden of costly inputs and failing crops has fallen on farmers, leading to spiralling debts and farmer suicides. The impacts of climate change and ecologically destructive farming are primary reasons for this financial duress. However, the movement has yet to deeply address the challenges of transitioning towards socioeconomically just, climate-friendly agriculture.

Peasant movements around the world highlight the importance of collective spaces and knowledge-sharing between small farmers. The campsites in Delhi provide a unique opportunity to link socioeconomic farming struggles to their deep ecological roots. These are indeed difficult discussions, but the kisaan (farmer) movement has provided spaces to challenge caste, religious and gender-based oppression.

The movement’s strength is its broad alliances and solidarity, but it remains unclear whether it will link palpable socioeconomic injustices to environmental injustices and rights. The ecological origins of COVID-19 make these connections ever more pressing the world over.The Conversation

A brighter future for India’s energy sector?

In 2001, the Kutch District of Gujarat, India was struck by a magnitude 7.7 earthquake which killed around 20,000 people and destroyed nearly 400,000 homes. The total property damage was estimated at $5.5 billion and had a disastrous effect on what was already an ailing economy. In the aftermath of the earthquake, Narendra Modi, a member of the right-wing, Hindu nationalist Bharatiya Janata Party (BJP), became the Chief Minister of Gujarat and led the region out of darkness and into economic growth and prosperity. By 2007, Gujarat contained 5% of the total population yet accounted for 25% of total bank finance in India and continues to outpace growth in other states. Indeed, when I visited Kutch in January, it was clear that there was a growing and aspirational middle class population. Modi was recently elected Prime Minister of India, triumphing over Rhaul Ghandi, a member of the centre-left India National Congress (INC) Party, and with it became one of the most powerful players in the fight against climate change. So what does the future hold for the Indian energy sector?

Previous examples suggest that Modi wants to embrace the clean energy model. As Chief Minister of Gujarat, Modi bankrolled the largest single-location solar plant in Asia with an operating capacity of 55 megawatts and launched the first Asian governmental department dedicated to climate change. Before 2012, Gujarat had the highest share of renewable energy sources in India (~14%) and as Prime Minister, Modi plans to use solar power to supply energy to approximately 400 million people who still lack basic access to electricity. Yet some have accused Modi of losing interest in his solar revolution following his failure to submit an action plan for the Prime Ministers National Climate Change Action Plan in 2013.

Despite the solar revolution, India still generates 60-70% of its energy from non-renewable sources. The dominant non-renewable resource is coal which accounts for 40% of total energy production. Yet, output from Coal India Ltd, the largest coal producing company in India, has stagnated over the past few years and has consistently missed targets. If Modi is to revive coal production in India he has to address a number of issues including infrastructure, corruption and a lack of pricing power. Failure to meet last years target was also partly attributed to cyclone Phaline and monsoon flooding. This is also likely to affect future coal production; all IPCC models and scenarios predict an increase in both the mean and extreme precipitation of the Indian summer monsoon.

Although sitting on huge reserves of coal, India also has to import a staggering amount of coal. Last year, 152 million tons of coal were imported, an increase of 21% on last year, while only China and Japan imported more. In order to decrease their dependence on coal, India have began hunting for domestic oil reserves. Alternatively, Modi has spoke of strengthening ties with Russian President, Vladimer Putin, with the possibility of developing a Russian pipeline through the Altai region into northwest China and, eventually, to northern India. Although this would be a costly procedure, it may be easier to forge a relationship with Russia rather than China, who are India’s closest competitors in the energy market.

So what does this mean for India’s energy sector? Ultimately, coal will likely remain the backbone of India’s energy sector. This is problematic because coal generates nearly twice as much carbon dioxide for every megawatt-hour generated when compared to a natural gas-fired electric plant. In his rush for economic prosperity, will Modi forget about his solar revolution? On Monday, President Obama will unveil a plan to cut carbon emissions from power plants by as much as 25%, with an emphasis on reducing emissions from coal. If this is achieved, the US will have greater leverage over India and other heavy polluters such as China. Will this encourage Modi to reduce India’s reliance on coal? For now, I remain somewhat optimistic.

India-UK scientific seminar: Developing new records of global change

The Royal Society of London, which was founded in November 1660, is the oldest existing scientific society with a long history of working internationally. Indeed, in 1723, the Royal Society established the post of Foreign Secretary, nearly 60 years before the British government did. In 2014, science remains a global endeavour which requires both international discussion and collaboration. In order to facilitate international and collaborative study, the Royal Society recently funded a three-day seminar for Indian and UK climate scientists. The aim of the proposal was to help develop new records of past global change in India using a variety of geological and geochemical techniques.

The seminar, hosted by Professor Paul Pearson (Cardiff University) and Professor Pratul Saraswati (IIT Bombay), was held in Bhuj between the 15th and 18th of January. Bhuj is a relatively small city in the district of Kutch and is located approximately 100km from the Indian-Pakistan border. In 2001, Bhuj was devastated by a magnitude 7.7 earthquake. The death toll approached 20,000 and over 600,000 people were made homeless. However, since then, Bhuj has become an outstanding example of a town rebuilt from scratch thanks to government support and corporate involvement. The city has become the focal point of western India’s growth and more than 200 companies have been established in the region since 2001. Of particular importance is the cement manufacturing industry which exploits the abundance of lime- and clay-containing materials (e.g. limestone and shale).

The UK was represented by five scientists whose research encompassed the major disciplines in past climate research. Attendees were selected from a range of universities, including two participants from the Cabot Institute at the University of Bristol (Dr. Dan Lunt, a climate modeller based in the School of Geography, and myself, Gordon Inglis, an organic geochemist based in the School of Chemistry). Ten Indian scientists were also in attendance, including members from academia and industry. The primary aim of the seminar was to develop stronger international collaborations between India and the UK, with an emphasis upon developing new climate records from the Indian continent. The first two days were designated for individual presentations and focused upon the regional geology of India and a variety of analytical techniques available to both parties. The third day was spent in the field and allowed participants to visit the geological successions discussed in the seminar.

A particular highlight was a visit to the Deccan Traps. Encompassing most of central and western India, the Deccan Traps is the world’s largest continental flood-basalt province outside Siberia. The eruption is thought to occur between 68 and 65 million years ago, approximately coinciding with the Cretaceous-Paleogene mass extinction event, and is associated with the demise of the dinosaurs and other marine and terrestrial species. Although the event has been attributed to a large bolide impact in Mexico, the Deccan Traps were almost certainly a major contributor to this extinction. Ken Caldeira, an atmospheric scientist who works at the Carnegie Institution, has argued that the Deccan Traps may have been responsible for a 75ppm increase in carbon dioxide during this interval. Although this is relatively small in geological terms, it is comparable to the increase in CO2 that has occurred over the past 50 years as a result of anthropogenic climate change. In more recent times, geologists are studying whether the Deccan Traps can store CO2 derived from coal-fired power stations in an attempt to reverse anthropogenic climate change.

Although the visit to India was brief, the seminar was a success and both Indian and UK scientists showed a great deal of enthusiasm for developing future collaborations. In particular, there is great scope to reconstruct past climate records over the past 70 million years and how that has corresponded to major biotic events.
