Climate change could further limit equitable access to affordable, culturally acceptable, and healthy diets . Climate impacts on agricultural production and regional food availability will affect the composition of diets, which can have major consequences for health. Variable by region and context, healthy diets are an outcome of the four inter-connected domains of sustainable food systems, namely ecosystems, society, economics and health . Climate change limits the potential for healthy diets through adverse impacts on natural and human systems that are disproportionately experienced by low-income countries and communities . Climate-driven droughts, floods, storms, wildfires and extreme temperatures reduce food production potential by diminishing soil health, water security and biological and genetic diversity . Models project that climate-related reductions in food availability, specifically fruit and vegetables, could result in an additional 529,000 deaths a year by 2050 .
