The role of perceptions, goals and characteristics of wine growers on irrigation adoption in the context of climate change

Abstract : While climate change affects both water demand for agriculture and water resources, implementing irrigation at farm level is one straightforward option for agriculture adaptation. Yet, in drought- prone areas, widespread development of irrigation may strengthen water scarcity and thereby further increase farmers’ vulnerability to water stress. In this context, understanding the conditions of the adoption of irrigation is of outmost importance to characterize the process, the risks and the policy implications of climate change adaptation. This paper presents an empirical approach for understanding the factors driving current and envisioned irrigation at farm level, by combining Internet-survey data and terroir data (rainfall, temperature, and soil-water capacity) characterizing wine growers and farms in southeastern France (Languedoc-Roussillon). Survey data include current and future practices concerning soil-plant water management, the perceptions of past economic, regulatory, technical and climate changes, and socio-economic characteristics such as wine growers’ main objectives regarding the management of their farms. The sample gathers 28% of growers that are already irrigating their vines, 39% that are considering this option for the future and 41% that would implement irrigation by 2050 when faced with a climate change scenario. Results of different econometric models show that both terroir and socio-economic factors such as perceptions and objectives play significant roles in the adoption of irrigation. Specifically, perceptions of water scarcity seem to drive future irrigation projects much more than real water scarcity. These results carry important policy implications for water-demand forecasting and water- supply planning.
