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.

The theme for the International Day for Biological Diversity in 2013 chosen by the Convention for Biological Diversity (CBD) is “Water and Biodiversity”. This theme was chosen to coincide with the United Nations designation of 2013 as the International Year of Water Cooperation. The International day for Biological Diversity is celebrated annually on the 22nd of May.

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.

The area around Lake Moyua is experiencing severe soil degradation resulting from inappropriate agricultural practices. To reverse and control the degradation process, an IWRM Plan is implemented. By involving the communities, the aim is to restore the soil, the hydrological systems, forests and biodiversity, as well as the harmonisation of policies and implementation of management regulations. This case study consequently demonstrates the value of a bottom-up approach.
