Résumé partiel
Groundwater can be an important resource to increase farmers’ water security in canal irrigations systems. However, intensive pumping can render groundwater use socio-economically and environmentally unsustainable. This thesis demonstrates the importance of farmers’ spontaneous conjunctive use of groundwater and surface water and the potential of conjunctive water management in the context of intensive groundwater use for small scale agriculture in China. The research is based on primary data collected in three inland river basins in Northwest China. The data is analysed through both qualitative and quantitative research methods. Both surface water insecurity and agricultural intensification are identified as drivers of farmers’ spontaneous conjunctive water use. Moreover, the results show that in a hierarchical water bureaucracy like in China, the shared responsibility over surface water and groundwater at all management levels facilitates the emergence of conjunctive water management practices.
