ISLAMABAD: About a tenth of overall global greenhouse-gas emissions from agriculture could be traced back to food waste by mid-century, a new study shows.
The team from the Potsdam Institute for Climate Impact Research for the first time provided comprehensive food loss projections for countries around the world while also calculating the associated emissions.
Reducing food waste would offer the chance to ensure food security which is well known. Yet at the same time it could help mitigate angerous climate change, Medical Xpress reported.
“Reducing food waste can contribute to fighting hunger, but to some extent also prevent climate impacts like more intense weather extremes and sea-level rise,” lead author Ceren Hic said.
Even though food availability on a global average has been higher than required in theory, some developing countries still have to fight undernourishment or hunger.
“At the same time, agriculture is a major driver of climate change, accounting for more than 20 Percent of overall global greenhouse-gas emissions in 2010. Avoiding food loss and waste would therefore avoid unnecessary greenhouse-gas emissions and help mitigate climate change,” co-author Prajal Pradhan explained.
“More importantly, food availability and requirement ratio show a linear relationship with human development, indicating that richer countries consume more food than is healthy or simply waste it,” Pradhan added.
Consequently, greenhouse-gas emissions associated with food waste could increase tremendously from today 0.5 to 1.9-2.5 Gigatons of CO2 equivalents per year by 2050, the study shows. APP
