Researchers outline urgent steps to improve food security in the face of increasing natural disasters caused by the climate crisis
The climate crisis is threatening food stocks in sub-Saharan Africa, but a comprehensive approach to food, farming and resources could increase crop production by more than 500% in some countries in the region, according to newThere is no single technological fix to the threat posed by the barrage of natural disasters striking the region, they said, but significant improvements could be achieved with new approaches, based on modelling done by the network of researchers in Malawi, Tanzania,...
The researchers produced a tool that quantified crop yields, land and water use as well as greenhouse gas emissions and nutrition to model the effects of the changing climate and how policies could have an impact.There had been successful trials of agricultural methods such as terracing, said researchers, as a way to improve soil health and water availability. The report added that developing new crop varieties was crucial to cope with extreme temperatures and rainfall.
According to the research, Malawi’s crucial maize yields could fall by a fifth by 2050 without action, but with a coordinated approach to technology, agriculture, infrastructure and food security, its production could increase by more than 700%.The four-year research project was produced by a partnership of organisations based in the countries studied and the UK.
