Farming in Africa: How Climate Change Hurts Crop Yields

Agriculture is the backbone of many African countries, but climate change is making it tougher to grow crops. A recent study looked at cereal crops in 35 sub-Saharan countries from 2005 to 2020. It found that farmers were pretty efficient, with an average score of 83%. However, climate change is hurting the productivity of land, labour, and fertilizers. The study used special math models to find out what helped and what hurt crop yields. Labour and fertilizers boosted efficiency, while more land per hectare actually reduced it. Climate change, measured by CO2 and methane emissions, made things worse. It lowered the productivity of land, labour, and fertilizers. But there's good news! Wealthier countries had better overall farm productivity. So, what can be done? The study suggests that farmers should use better seeds and machines that can resist bad weather. They should also combine skilled labour with new farming technologies. This could help increase crop yields and fight back against climate change.
