Diagnostic of agricultural production systems in the Lake Guiers area, Senegal

The dataset was constructed from surveys of 310 farmers operating in irrigated agricultural zones surrounding Lake Guiers in northern Senegal. The survey was carried out from the 09 to the 20 of March 2023, using KoboToolbox, with a questionnaire aiming at collecting information about: 1) farmers’ agricultural practices with a particular focus on pesticides and fertilizers use; 2) their socio-economic environment; 3) their perception of changes of climatic conditions and biotic pressures within agroecosystems and production limiting factors; 4) and the level of integration of agroecological practices in their systems. Farmers were selected to represent the main agricultural systems and cover the entire lake region. The dataset provides the first comprehensive description of farming systems and agroecological practices around Lake Guiers, offering a robust basis to analyze their diversity, dynamics, and environmental performance. It can serve as both a cross-sectional baseline and a reference for future longitudinal studies, supporting econometric, ecological, and policy analyses aimed at guiding the agroecological transition and informing sustainable land and water management in sub-Sahelian contexts.
