The Indus Waters Treaty of 1960 has kept two nuclear-armed rivals – India and Pakistan – in a stable river sharing arrangement for more than six decades. Yet that significant achievement now seems to be at risk.

India’s government has stated it is holding the treaty in abeyance and is threatening to cut off water to Pakistan after a terrorist attack killed more than 20 Indian citizens in late April 2025. India’s Prime Minister Narendra Modi described the treaty as a “blunder” and a “betrayal” of India’s dignity committed by then Prime Minister Jawaharlal Nehru, and proclaimed that “blood and water cannot flow together.”

The Mining Town Funding Congo’s Rebels and Tech Giants (Reuters)

In April 2024, the M23 rebel group seized control of Rubaya, a mining town that produces 15% of the world’s coltan—a critical mineral worth used in mobile phones, computers, and aerospace components. Rebels imposed a parallel administration in the town, and placed a 15% tax on mineral traders that generates $800,000 monthly from levies. Thousands of impoverished miners in the town, however, still work 12-hour shifts in dangerous conditions earning just $5.15 per day.

Low Political Will and Depleted Supplies: Inside Iran’s Water Crisis  (The New York Times) 

Water shortages are a day-to-day reality for many Iranians, as reservoirs shrink, taps run dry for hours, and water pressure remains so low that it doesn’t reach above the second floor. This acute water crisis is driven by a confluence of climatic changes and poor water policies, as Iran’s five-year drought has combined with overdevelopment, excessive dam development, and draining groundwater for agriculture to push already dwindling supplies to the brink. 

In Myanmar’s resource-rich Kachin State, deforestation linked to illegal logging and mining has surged over the past decade. While the national government struggles to assert control, the Kachin Independence Organization (KIO)—a political organization seeking autonomy for Kachin State in Myanmar—has also stepped in to regulate land use, restrict timber harvests, and manage permits. These activities serve to conserve local ecosystems and extract revenue. KIO’s environmental governance is strategic, aiming to bolster civilian support and consolidate territorial control. It is also shaping how communities cope and adapt to climate change.

Somalia’s new Nationally Determined Contribution (NDC)—the country’s roadmap for climate mitigation and adaptation—does more than outline the country’s climate ambitions. It recognizes the connections between climate change and conflict and charts a course for peace.

The Mekong River’s seasonal floods nurture the world’s most productive inland fishery and irrigate rice paddies that feed millions. Approximately 70 million people live in the lower Mekong Basin, and 75% of them depend on fishing and farming for their livelihoods. But hydropower expansion and other development projects are fragmenting the river and disrupting its natural rhythms, with severe consequences for those living downstream.

Around the world, conflict and environmental risks are on the rise – and they’re often connected in complex ways. In the past five years alone, the number of global conflicts has doubled. At the same time, human activity is pushing the planet beyond the ‘safe operating space’, increasing the risk of instability.

Researchers studying the links between conflict and environmental change have found that war and violence almost always harm the environment. But the reverse connection – whether environmental stress leads to conflict – is much harder to pin down. That’s because political systems, local institutions, and social dynamics often shape how environmental pressures play out.

Findings from recent studies suggest that sustainability and peace are positively correlated. In other words, the results suggest that peace and sustainability go hand in hand. If true, pursuing one could help achieve the other. But what if it’s not that simple?

In a rural, hard-to-reach area of Blantyre district in southern Malawi, Ephraim Louis cannot imagine where his life would be without the solar panel on the roof of his house. “I am not a captive of darkness anymore,” says Louis, 42. “It’s been more than 10 years since I installed this [solar panel] system. We still don’t have the main grid anywhere near us and no one here thinks it will ever come.”
