Farmers’ perceptions of climate change and adaptation strategies on sorghum productivity in the Sudanian and Sahelian zones of Mali

Abstract

In Mali, climate change is a major threat to the productivity of food security crops such as sorghum (Sorghum bicolor (L.) Moench, 1794). The objective of this study was to analyse farmers’ perceptions of climate change effects, on sorghum productivity and the adaptation related strategies. A total of 352 sorghum farmers in the Sudanian and Sahelian zones of Mali were interviewed, using a semi-structured questionnaire. Data collected were related mainly to the farmers’ socio-economic profiles, indicators used to characterise climate change and strategies developed to cope with it. Irregular rainfall, marked rise in temperatures and early cessation of the rainy seasons were the main manifestations of climate change effects according to the respondents. These effects reportedly resulted in a drastic drop in sorghum yields. Use of meteorological information (19.89% of the respondents), use of early and drought-resistant varieties (13.35% of the respondents), and intercropping of sorghum with other crops (25.85% of the respondents) were the strategy options adapted by farmers. The choice of an adaptation strategies was largely dependent on the number of years of experience in sorghum production, and the number of labour providers available in the household. It is imperative to assess and refine the agronomic effectiveness of these coping strategies to improve sorghum productivity in the study areas.
