Facing Droughts in Mediterranean Rainfed Agroecosystems: Farmers' Perception on Exogenous Run-Off Harvesting Techniques
Résumé
Runoff harvesting techniques (RHT) are efficient methods to enhance agricultural resilience in the face of climate change, including increased severity and decreased return periods of droughts, alongside annual rainfall pattern alterations. They can indeed reduce surface run-off, soil loss, collect water during rainfall of various intensities, enhance the soil water content in the rooting zone and consequently increase crop yields significantly. However, their implementation process is complex in agroecosystems due to land tenure, upstream-downstream dependencies and must involve all local actors from farmers to water management organizations and be considered at the watershed level to take into account hydrological, environmental, historical and socio-economical local context. Besides, no study on endogen or exogen techniques importation has been conducted in a given context where farmers already encounter high water resource tensions. To fill this gap, the proposed study analyzed farmers’ perception of RHT in a district in the south of France where institutional actors are willing to study and support RHT deployment. Face-to-face interviews were conducted for a quantitative analysis and narrative perspectives concerning farmers' vision of RHT, endemic or imported from southern contexts were analyzed. According to farmer’s relationship to water management, results show clear positive or negative perceptions of RHT according to their endemic property, and results enable us to make recommendations to institutional territory actors for RHT experimentation in the region.
