A new study published earlier this month in Frontiers in Sustainable Food Systems has uncovered a gap between advocacy and empirical evidence for scaling indigenous farming systems to counter climate change impacts on agriculture. Researchers led by Kamaljit Sangha at Charles Darwin University reviewed 49 articles on practices by Indigenous peoples and local communities, or IPLCs. The findings highlight benefits like soil protection and biodiversity support, but call for more data on productivity and economic value.

Scientists in Brazil and Peru are using machine learning for early outbreak predictions and Wolbachia-infected mosquitoes to curb dengue fever, amid rising cases fueled by climate change. In Lima, a 2024 epidemic overwhelmed hospitals, prompting adaptations now informing regional strategies. These efforts offer models as subtropical U.S. areas report local transmissions.

El Servicio Meteorológico Nacional anticipa de tres a cinco olas de calor en el centro de México de marzo a mayo de 2026, con temperaturas hasta 4 grados Celsius por encima del promedio. La Comisión Ambiental de la Megalópolis estima que esto podría activar hasta 15 días de contingencia por ozono, imponiendo restricciones vehiculares más estrictas en la Ciudad de México y el Estado de México.

A study on the scarlet monkeyflower (Mimulus cardinalis) shows it recovered from a severe drought in California via rapid evolution, marking the first observed case of evolutionary rescue in the wild. Researchers led by Daniel Anstett at Cornell University tracked the plant's response to the 2012-2015 megadrought. While this offers hope for species facing climate change, experts note limitations for long-term adaptation.

New research indicates that rising ocean temperatures may benefit Nitrosopumilus maritimus, a microbe essential for marine nutrient cycles. This archaea adapts by using iron more efficiently in warmer, nutrient-poor conditions, potentially sustaining ocean productivity. The findings, published in the Proceedings of the National Academy of Sciences, suggest these microbes could play a larger role in ocean chemistry amid climate change.

Quality seeds resilient to climate change are the main pillar in preventing hunger and ensuring food security across Africa. According to Dr. Yacouba Diallo, Secretary General of the African Seed Trade Association (AFSTA), agricultural reforms cannot succeed without robust seed systems. AFSTA will host its 2026 congress in South Africa to discuss these issues.
