Continuing the balmy trend to 2021, the month of March ended as the world’s eighth-warmest March in 142 years of record-keeping.

On its Climate Science Information Centre, extended in February to South Africa, Facebook states that “at least 97% of published scientists agree that global warming is real and caused by humans”.

The global food system has a lot to answer for. It is a major driver of climate change, thanks to everything from deforestation to cows burping. Food production also transforms biodiverse landscapes into fields inhabited by a single crop or animal. It depletes valuable freshwater resources, and even pollutes ecosystems when fertilisers and manure washed into streams and rivers.

Agriculture and climate change are deeply intertwined. The effects of global warming on food supply are dire, whilst world population is increasing. It's time to change the way agriculture affects the environment, and vice versa.

The impact of climate change on agricultural productivity is having a disproportionate effect on poorer, warmer countries.

Organically farmed food has a bigger climate impact than conventionally farmed food, due to the greater areas of land required. This is the finding of a new international study involving Chalmers University of Technology, Sweden, published in the journal Nature.
