Climate Refugees: The Human Face of the Climate Crisis

In 2023, extreme weather events displaced approximately 26 million people from their homes — more than conflict and violence combined for the first time in recorded history. These are the world's climate refugees: people forced to flee not by war or political persecution, but by rising seas, more intense cyclones, prolonged droughts, catastrophic floods, and the slow, grinding degradation of the land and water resources they depend on for survival. 

The word 'refugee' still does not officially apply to people displaced by climate change under international law. The 1951 Refugee Convention protects people fleeing political persecution, but offers no legal protection to those fleeing climate-induced disasters. This legal gap leaves climate-displaced people in a precarious position, unable to access the protection, support, and resettlement options available to recognized refugees. Closing this gap is one of the most urgent human rights challenges of our time. 

The stories of climate displacement are heartbreaking in their specificity. In the Sundarbans of West Bengal, families who have lived on the same islands for generations are watching their land sink beneath the rising Bay of Bengal, metre by metre, year by year. In coastal Odisha and Andhra Pradesh, fisher communities are being forced inland by the increasing frequency and intensity of cyclones. In Rajasthan and Bundelkhand, prolonged droughts are emptying entire villages as farmers who can no longer grow crops or find water migrate to already overcrowded cities. 

Bangladesh is often cited as ground zero for climate displacement. The country is one of the most densely populated and climate-vulnerable nations on Earth. Rising sea levels, increasing salinity in coastal farmland, intensifying cyclones, and Brahmaputra River flooding are already displacing hundreds of thousands of Bangladeshis every year, many of whom migrate to Dhaka or attempt to cross into India. The scale of future displacement, absent dramatic global climate action, is almost incomprehensible. 

Sub-Saharan Africa presents another dimension of the crisis. In the Sahel region, a decades-long desertification trend driven by climate change, overgrazing, and deforestation is shrinking the area of productive farmland and pastoral land available to tens of millions of people. Competition over water and grazing rights is fuelling conflict. Young men with no economic future in their home communities are moving to cities or attempting the desperate journey across the Mediterranean to Europe — not primarily because of war, but because their land can no longer support them. 

The Internal Displacement Monitoring Centre projects that without ambitious climate action, climate change could force over 1 billion people to migrate by 2050. To put this in perspective, the entire human population of the Earth was 1 billion in the year 1800. We could see, in a single century, a forced displacement of people larger than the entire world population of two hundred years ago. The humanitarian system, already stretched to breaking point, simply cannot absorb this scale of displacement. 

India is both a major contributor to climate change through its historical and current emissions, and one of the countries most vulnerable to its impacts. The Indian government has committed to ambitious climate targets, and India's renewable energy transition is genuinely impressive. But ambition must translate into action at the speed and scale that the science demands — not just for India's own sake, but out of solidarity with the most vulnerable communities within India and around the world. 

The climate crisis is fundamentally a justice issue. The people being displaced by climate change today — in Bangladesh's deltas, India's coastlines, Africa's drylands — are overwhelmingly the people who have contributed least to the greenhouse gas emissions that are causing it. They deserve not just our sympathy but concrete action: aggressive emission cuts, robust adaptation funding, and a legal framework that recognizes and protects climate refugees. Climate justice is not a slogan. It is an obligation.

Wetlands: Earth's Most Undervalued Superheroes Are Disappearing

If you were to design the perfect ecosystem — one that cleaned water, prevented floods, stored carbon, supported extraordinary biodiversity, regulated rainfall, provided food and livelihoods to millions of people, and protected coastlines from storms and sea level rise — you would design a wetland. These remarkable ecosystems, often dismissed as muddy wastelands or breeding grounds for mosquitoes, are in fact among the most valuable and productive habitats on the planet. 

Wetlands — a broad category that includes marshes, swamps, bogs, peatlands, floodplains, estuaries, mangroves, coral reefs, and shallow coastal waters — cover only about 6% of Earth's land surface. Yet they support nearly 40% of all the world's known species. They are extraordinarily rich in life: a single hectare of wetland may contain more species of insects than an entire square kilometre of farmland. 

India is blessed with exceptional wetland wealth. The country has over 750,000 wetlands covering nearly 4.7% of its geographical area. These range from the magnificent Chilika Lake in Odisha — Asia's largest coastal lagoon and a globally important bird wintering ground — to the Wular Lake in Jammu and Kashmir, the Keoladeo National Park in Rajasthan, the flamingo habitats of the Rann of Kutch, and the mangrove forests of the Sundarbans. India has 75 Ramsar sites — wetlands recognized under the international Ramsar Convention as being of global importance. 

The ecosystem services that wetlands provide to humanity are staggering in their value. Wetlands act as natural water purifiers, filtering out pollutants, sediments, and pathogens as water flows through them. They act as giant sponges, absorbing excess rainfall and slowly releasing it, reducing both the severity of floods and the severity of droughts. In a single monsoon season, a large wetland can absorb billions of litres of water that would otherwise flood fields, roads, and homes. 

Wetlands store enormous amounts of carbon — particularly peat bogs, which have been accumulating organic material for thousands of years. When wetlands are drained or degraded, this stored carbon is released into the atmosphere as CO2 and methane, significantly worsening climate change. Protecting intact wetlands is therefore one of the most cost-effective climate solutions available — no technology required, just the wisdom to leave them alone. 

Wetlands are also among the most important fisheries in the world. Approximately two-thirds of all commercially important marine fish species spend part of their life cycle in coastal wetlands, using mangroves and estuaries as nurseries for their young. The livelihoods of hundreds of millions of people — particularly coastal fishing communities in India — depend directly on healthy, productive wetlands. 

Yet we are destroying wetlands at three times the rate at which we are losing forests. Since 1970, the world has lost approximately 35% of its wetlands. In India, rapid urbanization is swallowing coastal and inland wetlands. Agricultural drainage converts marshes and floodplains into farmland. Industrial effluents and sewage pollute and degrade wetland ecosystems. Invasive aquatic plants like water hyacinth choke thousands of water bodies. And climate change is altering the hydrology of wetlands across the country.

The loss of wetlands is not inevitable. Communities across India are demonstrating that with the right support and policies, wetlands can be restored and protected. The revival of traditional community pond management systems, the restoration of degraded mangroves, and the removal of invasive species are all yielding results. World Wetlands Day on February 2 each year is an opportunity to remember what we stand to lose — and to renew our commitment to protecting Earth's blue-green heart. 

India has a powerful opportunity to demonstrate global wetland leadership. The country's 75 Ramsar sites, its vibrant community conservation tradition, and its ancient cultural reverence for water bodies provide a strong foundation. What is needed is sustained political commitment, adequate funding for wetland monitoring and restoration, and a shift in public consciousness that sees wetlands not as wastelands but as the irreplaceable natural infrastructure they truly are. A nation that protects its wetlands protects its water, its food, its coasts, its climate, and its extraordinary natural heritage.

India's Groundwater Is Disappearing

 

India is facing one of the most severe groundwater crises in the world. According to NITI Aayog, 21 major Indian cities are expected to run out of groundwater by 2030, affecting over 100 million people. This is not a distant threat — it is happening right now.

Groundwater accounts for nearly 63% of all irrigation water in India and supplies drinking water to over 85% of rural households. When this invisible reservoir disappears, the consequences are catastrophic — crop failures, mass migration, and public health emergencies.

The primary culprits are over-extraction, poor water management, and the rapid concrete paving of cities that prevents rainwater from seeping back into the earth. In states like Punjab, Haryana, and Rajasthan, water tables are dropping by 1–3 metres every single year.

What can we do? Rainwater harvesting must become mandatory in every building — urban and rural. Farmers need support to shift away from water-intensive crops like paddy and sugarcane.
And every one of us must treat water not as an unlimited resource, but as the precious, finite
lifeline it truly is.

The time for awareness has passed. The time for urgent, decisive action is now.

Our Rivers Are Dying

Ganga, Krishna, Narmada, Kaveri – many of our great rivers are depleting fast. If we do not act now, the legacy we hand over to the next generation will be one of conflict and deprivation. These rivers nurtured and nourished us for thousands of years. It is time we nurture and nourish them back to health.

Saving Our Rivers

The simplest solution to rejuvenate India’s rivers is to maintain a minimum of one kilometer tree cover on riversides.

Forest trees can be planted on government land and tree-based agriculture brought in on farm land. This will ensure our rivers are fed throughout the year by the moist soil. This will also reduce floods, drought and soil loss, and increase farmers’ incomes. Learn More
