Stakeholder-based water allocation modelling and ecosystem services trade-off analysis: the case of El Carracillo region (Spain)

Equitable water allocation in the context of local-scale water conflicts can be challenging. We present a holistic framework for the analysis of small-scale water disputes, contributing an integrated approach to the analysis of water conflicts by providing technical solutions combined with an in-depth analysis of social dynamics. The analysis focuses on an ongoing water conflict in El Carracillo region (Spain) related to an artificial aquifer recharge project. This case study involves two competing water users: horticultural farmers and ecosystem services provided by Cega River, from which water is diverted in order to recharge the aquifer. Based on a stakeholder analysis, a tool was developed to support participatory processes by facilitating mediation procedures. Preliminary results show solutions exist that account for ecosystem needs without causing major negative impacts on El Carracillo agriculture, and suggest the need for a re-negotiation of the existing rules governing water diversion from Cega River.
