How climate change affects farming and food security
Live MintAs impacts from prolonged droughts to extreme heat worsen, climate change is threatening the world's ability to produce enough nutritious food and ensure everyone has access to it. At COP28 in Dubai, more than 130 country leaders on Friday called for global and national food systems to be rethought to address climate change - the first such official recognition at a U.N. climate summit of growing worries about food security and planet-heating emissions from agriculture. The Climate Focus survey of 13 countries in Asia, Africa and Latin America found nearly 440 million small-scale farmer households now spend about $368 billion annually on adaptation costs, or about $838 each per year. Analysts say efforts to shore up global food security also need to reach well beyond farms, to try to rein in speculators in food markets, discourage export clampdowns and revamp increasingly overwhelmed humanitarian aid systems.
