This report addresses multilevel governance challenges in water policy in the Latin American and the Caribbean (LAC) and identifies good practices for co-ordinating water across ministries, between levels of government, and across local and regional actors. Based on the OECD Multilevel Governance Framework and a survey on water governance, the report i) maps the allocation of roles and responsibilities in 13 LAC countries’ water policy at central government and sub-national level; ii) identifies the main coordination “gaps” in terms of territorial and institutional fragmentation, funding mismatch, information asymmetry, accountability, objectives and capacity, and iii) provides a range of mechanisms to improve water governance at all levels and foster capacity-building.
