Climate Change and Food Security
Coverage from Fortune, Reuters, and others
Climate change affects food systems from farms and soils to storage, trade, prices, diets, and public health.
Heatwaves, droughts, floods, shifting rainfall, and sea-level rise can reduce yields, increase crop-failure risk in major breadbaskets, weaken soil and water functions, and lower the nutritional value of staples such as wheat and rice. These pressures are unevenly distributed, with particular risks for lower-income populations, import-dependent small island states, and rain-fed farming regions. Responses include better water and soil management, resilient crop varieties, early warnings, social protection, regional storage, stronger supply chains, and agricultural innovation.
