Steadily shrinking for decades due to unsustainable irrigation policies, the Aral Sea is under increasing pressure, making both allocation and availability major challenges. Action has been taken and the Basin Economic Allocation Model has been developed as a long-term decision support system to facilitate putting “value on water use”. This demonstrates that economic models can be applied to assess economic value maximization of different water uses.
To supply water to a growing population, an aqueduct was built in the watershed of El Limón River in Tovar municipality. However, this aqueduct does not provide sufficient supply, creating conflicts among the communities. To solve these, agreements on the use and conservation of water resources have been made among the communities, involving both rural villages and urban areas. This illustrates the benefits of a participatory approach.
The objectives of the programme are to support participating countries to:
Tourism has placed great pressure on the natural environment of Jamaica. Action was taken through a USAID funded project that aimed to increase water use efficiency and improve environmental management. The key lessons are the value of demonstrating the benefits locally as well as to institutionalise the programme.
The Goascoran River basin is shared by Honduras and El Salvador and is of great environmental, economical and geopolitical importance. In 2006, action was taken to create a multi-sector instance to integrate, influence and coordinate sustainable management of the shared basin. This experience is of great value for IWRM, as the management group establishes a model of work for transboundary management.
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 Vietnam, there are two kinds of RBO; 1) The Management Board of River basin Planning (MBRBP), established and managed by Ministry of Agriculture and Rural Development (MARD) in a period from 1999-2001 in compliance with Law on Water Resources 1998. 2) The Committee for Environmental Protection of River Basin (CEPRB), established and also managed by the Ministry of Natural Resources and Environment (MONRE) during the time 2009-2010.
