Methodology and Criteria for the Allocation of Reused Water in Agriculture

Abstract

This chapter provides a methodology to analyse the allocation of reused water. The tool has been developed for the Guadalquivir River Basin Authority, allowing decision makers to rank the actions on the reutilization of urban water for agriculture. The decision support is based on four groups of attributes: (1) resource supply, (2) environmental impact, (3) technical and economic feasibility and (4) social and institutional impact. A multicriteria decision method is proposed to aggregate all selected indicators. The results allow the River Basin Authority to classify different water requests of reused water, according not only to their technical knowledge, but also to the experience of different experts and stakeholders in water management.
