The contamination of groundwater with arsenic is a global concern, threatening ecosystems and human health. In India’s Indo-Gangetic plains, researchers found high arsenic levels from natural and human sources are linked to skin lesions and cancer. Improved monitoring systems and community-engaged water governance are needed to promote safe drinking water.

Experts examine how nature-based solutions (NbS) are being adopted worldwide to advance climate and sustainability goals, drawing globally informed lessons from Indonesia. The study finds that effective NbS must be rooted in local socio-ecological contexts while aligning with global frameworks.

New report from the World Economic Forum and Frontiers identifies 10 technologies with the potential to accelerate climate action, restore ecosystems, and drive sustainable innovation within planetary boundaries.

Researchers explore how climate change, conflict, migration and displacement, and health interact in humanitarian settings. They found that climate impacts often worsen existing vulnerabilities, emphasizing the need for collaboration across research, policy, and health systems to strengthen community resilience.

For the first time, researchers looked at the long-term Omega-3 supply from Mediterranean fisheries and found that warming seas and declining fish stocks are reducing it. Gains from warm-water fish can’t make up for losses from temperate and cold-water species, putting future Omega-3 from seafood at serious risk.

The EAT-Lancet Commission presents new evidence on nutrition and health within safe and just planetary boundaries, including updates to the Planetary Health Diet, assessments of food systems’ impacts on the Earth system, and action-oriented recommendations.

Through interviews with women and healthcare workers, this study explores how climate change and extreme weather affect reproductive, maternal, and child health in Tanzania’s Kilwa District. Results show that floods, droughts, and rising temperatures limit access to care, increase disease and malnutrition risks, and heighten gender-based violence.

The report is the first global overview of the health harms of fossil fuels across their entire lifecycle and the human lifespan. From toxic exposures during extraction to pollution-related disease, the findings call for governments, health professionals, and civil society to accelerate a just, equitable transition away from fossil fuels. Available in English, Spanish, Portuguese, and French.

Due to global warming, heat-related illness is rising worldwide. In Taiwan, over 100,000 cases were reported in the past two decades, with heat stroke being the most common and deadliest. Researchers emphasize the urgent need for stronger prevention and treatment strategies.

This study looked at how people are responding to rising coastal climate risks worldwide. While many communities have moved away from the coast, 46% of vulnerable low-income regions, particularly in Africa and Asia, were forced to stay put or move closer, exposing deep inequities in climate adaptation.

The Planetary Health Check assesses the planetary boundaries–the nine processes that are known to regulate the stability, resilience, and life-support functions of our planet. Seven have now been breached, and for the first time, ocean acidification has tipped over, threatening reefs, fisheries, and even the oxygen we breathe.

Researchers estimate the health, environmental, and financial impacts of expanding sustainable school meals for all children by 2030. Findings suggest substantial health and environmental benefits at low cost across countries of all income levels, though dedicated policy and financial support will be needed in low-income countries to achieve universal school meals.
