Rainfed cereal yields remain low in the Central Plateau region, as at national level, despite the use of adaptation measures. The general objective of this book was to specify the impact of adaptation measures on sorghum and maize yields and their repercussions on producers' incomes in the Central Plateau region of Burkina Faso over the period 1991-2020. A sample of 240 farmers was drawn using Ardilly simple random sampling, prioritising the dominant crop in terms of area. The results were obtained by interviewing them, monitoring their farms during the 2021-2022 rainy season, using Landsat da...
Rainfed cereal yields remain low in the Central Plateau region, as at national level, despite the use of adaptation measures. The general objective of this book was to specify the impact of adaptation measures on sorghum and maize yields and their repercussions on producers' incomes in the Central Plateau region of Burkina Faso over the period 1991-2020. A sample of 240 farmers was drawn using Ardilly simple random sampling, prioritising the dominant crop in terms of area. The results were obtained by interviewing them, monitoring their farms during the 2021-2022 rainy season, using Landsat data and agricultural, meteorological and soil statistics. They show an increase in cumulative annual rainfall of 13.54, 22.04 and 75.29% at the Boussé, Ouagadougou and Boussouma stations, following a break in stationarity in 2008. In addition, an increase in end-of-season values and a high frequency of rainfall breaks in August and September were highlighted by the statistics and acknowledgedby growers.
