Heat and agriculture

As climate change accelerates, farmers face more frequent and intense extremes. While drought has long threatened wheat, this research shows that heatwaves during a key growth stage may soon pose an even greater risk to global harvests.

Increasingly extreme heatwaves are now posing a real threat to the crops and livestock on which we rely, as well as Australia’s wildlife and ecosystems.

This brief highlights how extreme heat, drought, and flooding are affecting agricultural livelihoods in Nyumanzi Refugee Settlement.

This publication examines how heat waves are increasingly disrupting interconnected food, energy, and water (FEW) systems, creating cascading risks that undermine resilience and sustainability.

This study investigates ecosystem impacts of marine heatwaves (MHWs) in the Western Mediterranean Sea using a spatially explicit Ecopath with Ecosim (EwE) food web modelling framework.

This report explores the impact of extreme heat on agricultural producers and on crops, livestock, fisheries and aquaculture, and forests worldwide.

This report argues for a strategic expansion of Anticipatory Action (AA) to more systematically include the agricultural components, to place it at the intersection of humanitarian response and long-term climate adaptation.

Extreme heat damages crops and increases the number of strongly undernourished households in terms of calories, iron, and other nutrients. While some households cope by buying food grown elsewhere, the poorest remain highly vulnerable.
