TS.B.2.3 Climate-related extremes have affected the productivity of agricultural, forestry and fishery sectors . Droughts, floods, wildfires and marine heatwaves contribute to reduced food availability and increased food prices, threatening food security, nutrition and livelihoods of millions of people across regions . Extreme events caused economic losses in forest productivity and crops and livestock farming, including losses in wheat production in 2012, 2016 and 2018, with the severity of impacts from extreme heat and drought tripling over the last 50 years in Europe . Forests were impacted by extreme heat and drought impacting timber sales, for example, in Europe . Marine heatwaves, including well-documented events along the west coast of North America  and east coast of Australia , have caused the collapse of regional fisheries and aquaculture . Human populations exposed to extreme weather and climate events are at risk of food insecurity with lower diversity in diets, leading to malnutrition and increased risk of disease .
