Decentralisation also means giving more prominent role to the Technical Groundwater Committees (COTAS) in aquifer management, strengthening the organisation and functioning of the River Basin Councils and their auxiliary bodies, and consolidating the governance functions and regional organisation of the CONAGUA. There is no “one size fits all” model for enhancing public governance in the water sector and overcoming institutional obstacles to implementation but it is critical to diagnose the main governance challenges experienced across ministries and public agencies, between levels of government and across subnational actors and review existing governance instruments. This will help clearly define roles and responsibilities of public authorities and set-up to dispute resolution mechanisms.
