Farmers in the Great Lakes region of Africa, including Uganda, Rwanda, and Kenya, face increasing challenges from climate change, which is predicted to spread crop diseases and pests. A study highlights that 44% of pathogens may become more common at higher altitudes, threatening food security for millions of smallholder farmers.
- 01Climate change is expected to alter the distribution of crop diseases and pests in the Great Lakes region.
- 02The study found that 44% of sampled pathogens and pests could thrive at higher altitudes due to rising temperatures.
- 03Farmers need to adopt climate-smart agriculture practices to mitigate these challenges.
- 04Not all pests will increase; 17% may become less common in warmer conditions.
- 05Improved monitoring and predictive tools are essential for effective pest management.

Farming in the Great Lakes region of Africa, which includes countries like Uganda, Rwanda, Burundi, the Democratic Republic of Congo, Tanzania, and Kenya, is increasingly threatened by climate change. A recent study sampled 27 crop pathogens and pests affecting key crops such as banana and cassava. The research utilized machine learning to predict how rising temperatures could facilitate the spread of these threats. Findings indicate that 44% of these pathogens and pests may become more prevalent at higher altitudes as climate warms, posing significant risks to food security for millions of smallholder farmers. Conversely, 17% of the sampled species may decline in warmer conditions. To combat these challenges, farmers and agricultural stakeholders are urged to implement climate-smart agriculture practices and improve pest management strategies. Enhanced monitoring and predictive tools are crucial for anticipating pest outbreaks and ensuring crop health. However, many national organizations face resource constraints that hinder comprehensive monitoring efforts. Addressing these issues will be vital for safeguarding agricultural productivity in the region.
