by The Lancet’s latest report on the countdown to health and climate changesay,Climate change is affecting every pillar of food security. Rising temperatures and extreme weather events directly threaten crop yields, shortening the growing season for maize by 9.3 days, rice by 1.7 days, and winter and spring wheat by 6 days. The number of people reporting moderate to severe food insecurity in 103 countries increased by 98 million per year in 2020 compared to the period 1981-2010, linked to extreme heat. The global average annual 29 percent increase in land area affected by extreme drought from 2012-2021 compared to 1951-1960 puts people at risk of water and food insecurity. Compared with 1986-2005, from 2012 to 2021, children under the age of 1 experienced a total of 600 million more heatwave days (4.4 more days per child), and adults over the age of 65 experienced a total of 3.1 billion more days (more than 4.4 days per person). 3.2 days). Heat-related deaths increased by 68% in 2017-2021 compared to 2000-2004; human exposure to very high or very high fires in 61% of countries between 2001-2004 and 2018-2021 The number of dangerous days has increased. Heat exposure causes a global loss of 470 billion hours of potential labor time in 2021, a loss of income equivalent to a significant portion of national GDP, disproportionately affects low- and middle-income countries (5.6% in low- and middle-income countries), and exacerbates life The impact of the cost crisis.
