Se ha creado en Nicaragua la “Comisión de Desarrollo Sostenible de la Cuenca del Lago Cocibolca y el Río San Juan”, en cumplimiento de la Ley 626, y de la Política Nacional de Recursos Hídricos oficializada en el año 2001. La responsabilidad principal de esta Comisión es “Elaborar y aprobar el Plan de Acción y de Ordenamiento Territorial para la Gestión de la Cuenca”, además de “implementar y dar seguimiento” a los mismos.
The area of Zarati river sub basin belongs to important water recharge zones. There is, however, a need to restore the area, which has been susceptible to degradation. Action has been taken in a bottom-up manner, applying Participatory Rural Assessment. Important lessons can be drawn from this in terms of IWRM, as it sets a clear example of active participation of the communities and the local authorities.
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.
The Prespa basin was affected by over-abstraction and diversion of water, wetland drainage, deforestation and overgrazing, leading to danger for human livelihoods and ecosystems. Action was taken by WWF through the creation of the Society for the Protection of Prespa, eventually culminating in the creation of Prespa National Park. The lesson drawn is that to change the perspective of local stakeholders to ensure that they share a common vision is vital for success.
In Slovenia, water is extracted for drinking water, energy, fish-farming, irrigation and technological purposes. In order to avoid over-extraction, an Environmental Flow framework has been implemented, assessing within what limits water can be extracted, using hydromorphological, hydrological, hydraulic and ecological criteria. The case shows that it is important to combine policy decisions with expert evaluations.
