Water, which might appear as a gift from nature, actually needs huge human investment in order to serve the varied and growing global demand on this resource. Creating the investment structures and securing the funding to meet water needs is a key enabling factor to achieving good water governance.

Legal frameworks play an important role in the management of water resources at a range of scales – from local and national legislation covering domestic use, to international treaties that govern waters shared by sovereign nations.

It is often said that the current water crisis is mainly a crisis of governance, much more than a crisis of water shortage or water pollution per se. In the context of IWRM, governance is defined as the range of political, social, economic and administrative institutions that are in place (or need to be in place) to develop and manage water resources in sustainable manners. This section identifies four institutional roles that must be fulfilled for water governance systems to achieve sound IWRM practices: B1 – Regulation and Enforcement; B2 – Water Supply and Sanitation Services; B3 – Coordination and Facilitation; and B4 – Capacity Building.

Wathersheds of Tacana originate on the volcano, with both shared by Guatemala and Mexico. This region is of great strategic importance for both countries since they supply water to a large number of residents in the cities located downstream and are the main source of irrigation water for agriculture. In the lower reaches, fishing is an important source of income.

The Lempa River is shared by Guatemala, El Salvador and Honduras, making its management a good example of transboundary cooperation. To reach consensus, action was taken to develop a treaty as part of a regional process.  However, since the treaty was not accompanied by strategies designed by local actors, it is somewhat weak. Nonetheless, this case illustrates that political willingness is crucial for advancing towards IWRM in transboundary watersheds. 

The San Juan River waters have experienced deterioration due to poor management of its basin. To address the issues, action has been taken to implement IWRM to address the areas of water, soil, forests and municipal development in a cross-sectoral manner.  This case study is a good reminder of the integrated nature of IWRM, and the importance of a model that accounts for management of both water and land.
