Africa is facing increasing complications in farming as climate change makes weather more unpredictable and leads to mass desertification of previously farmable land. Conservation agriculture (CA) has been touted for decades as the solution, not only to farming in climate change, but as a way to sequester Carbon in soil and actively combat climate change through agriculture.
A new study shows that while CA is well suited to helping farmers adapt to, and even increase profits in changing climates, there is considerable uncertainty about how much CA contributes to the mitigation aspect.
Overall the authors emphasized that the main benefit of CA is the adaptation potential, which helps farmers markedly improve productivity, achieve stable yields and decrease labor inputs, but further research is needed to determine effects on climate change.
