Groundwater is relied upon for roughly half of global drinking water. And as climate change alters precipitation patterns and pollution of surface water continues to increase, our collective dependence on groundwater is likely to increase.

Getting ahead of the potential conflicts, or in some cases, catching up with them, requires an increase in effective groundwater cooperation and diplomacy. Yet the vast majority of transboundary aquifers exist without any form of agreement among the states that share them. This state of affairs leaves the aquifers—and the people who rely upon them—vulnerable to overexploitation, environmental degradation, and the risk of interstate conflict.

Organizing Regional Action on Climate Change, Health, and Environment

As the 2030 deadline for the Sustainable Development Goals looms, the World Health Organization has proposed a new regional framework that aims to build climate-resilient and sustainable health systems, improve the health sector’s access to climate funding, and build an evidence base for policymaking.

More than 11,300 people are confirmed to have died in the floods that struck eastern Libya on September 11, 2023, far surpassing many estimates of the death toll in the country’s 2011 civil war. Thousands are still missing. Flooding has washed away approximately 25% of the city of Derna, and damage to roads and bridges is curtailing emergency service access. A rapid attribution study estimated that the extreme rain was at least a “1-in-300 year event.” This is far beyond previously recorded incidents, yet such incidents are now up to 50 times more likely—and up to 50% more intense—when compared to a 1.2°C cooler climate.

A Warming World is Accelerating the Spread of Dengue

Dengue is now endemic in most Latin American countries. But scientists warn that a warming climate is increasing the pace of breeding and transmission of dengue-carrying mosquitoes, and bring them into new countries.

The UN Environment Programme has described Africa as the most vulnerable region in the world to climate change. Despite only being responsible for 3% of global emissions, the continent has been battered by extreme weather events, including droughts, cyclones, wildfires, and sandstorms. One in three people across Africa faces water scarcity. The continent’s agricultural sector, which represents a significant share of African countries’ GDP and employment, is highly exposed to climate change.

When catastrophic floods struck civil war-ridden Libya in the late summer of 2023, the catastrophe caused over 10,000 deaths and wreaked immense destruction throughout the nation’s northeastern regions. But because none of the warring factions were in full control of the country and international responders were concerned about being caught in the crossfire, relief efforts were delayed and limited. This confluence of factors amplified human suffering, particularly in Libya’s remote and worst-affected areas.

Converging Crises: Pakistan Flood Victims Face Rising Hunger

According to FAO, Pakistan ranks among the top-ten world producers of wheat, cotton, sugarcane, and mango—and it is the 10^th largest producer of rice. But Pakistan is also atop another world ranking: vulnerability to the impacts of global warming.

Treading Water: Why Were Libya’s Floods So Devastating? 

This week’s devastating disasters in Morocco and Libya underscore the cascading effects of environmental shocks (and in the case of Libya, climate-related shocks), as well as the cross-sectoral response needed to comprehensively address the damage.
