Climate Change putting a big dent in global coffee production Mario Picazo mardi, 16 juillet 2019 à 13:10 - Rising global temperatures are having a serious effect on some of the world's traditional sources of coffee. Climate Change is affecting coffee production around the world, and one of the most affected countries is Colombia. The South American nation, a leading exporter of prime Arabica coffee, has lost close to 40,000 hectares of coffee plantation land in the last 18 months, representing more than four per cent of the country's total acreage used for coffee cultivation. According to Colombia's National Federation of Coffee Growers (Fedecafé), since the 1990s the amount of land used for coffee cultivation has shrunk by 20 per cent, and the decline is likely to accelerate in the coming years.
