greater effect than in the control group. Farmers believe that the planting dates of the
experimental plots have been more accurate. As a result, 93% of households indicate
that they need climate information to guide their decision-making.
5 Conclusion
In Burkina Faso, the stakes of climate change are considerable. Several recent studies
have analyzed historic climate parameters (rainfall, temperature, evapotranspiration)
and surface water resources in the country. In the Nakanbe basin, results show an
increasing trend in surface runoff, suggesting that it could face a highly variable
climate and the hydrological regime in the coming decades, ranging from heavy
rainfall that leads to flooding to severe drought that leads to water scarcity and a
reduction in crop yields.
Agricultural innovation is a critical strategy to reduce household vulnerability to
climate change. According to a 2009 report by CILSS and the Centre for International
