The Pillahuinco basin is located in one of the most productive regions of Argentina. It is within the roads that connect the southernmost parts of the country with the capital and the far north, as well as the Andean provinces of the west with the ports of the Atlantic coast, intersect there. The basin covers a region with a distinct topography, presenting a highland area with elevations between 250 and 650 meters. With a plain that can reach about 125 meters where agricultural activities predominate. The agriculture activities have resulted to environmental problems calling for an approach that can provide solutions to support sustainable development of the basin.
Phnom Penh, the capital of the Kingdom of Cambodia, lies on the confluence of the Mekong and the Tonle and Bassac rivers. These rivers are the main source of freshwater for the city’s population of about 1.3 million. Many of the Asian cities’ publicly managed water utilities perform below their potential. Cambodia’s Phnom Penh Water Supply Authority (PPWSA) undertook major reforms and transformed a war-ravaged water utility into a commendable model that stands for other cities to emulate
The Maltese islands experience acute water shortage as an area. To address this, leakage control has been developed to become a strategically important component for water resource management, and has been used to reach an optimum economic balance between water supply and water demand. The key lesson is that leakage management is an effective supply side action to increase efficiency in water use leading, and can be used as a strategic tool.
The DRC Country Water Partnership (DRC-CWP) was established in November 2004. The Partnership was established to assist government and other actors to promote Integrated Water Resource Management (IWRM) principles in the water sector and related sectors. The Partnership is hosted by The National Committee of Water and Sanitation.
Many climate change models predict that increasing temperatures, droughts, heavy precipitation and other extreme climatic events will have severe impacts on family farmers. Yields might be reduced by up to 50 percent in dry regions at the same time as family farming continues to be the basis unit of the agricultural economy in developing countries.
Due to substantial population growth putting increased pressure on the water resources, their quality has started to deteriorate. This is perceived as a serious issue since water is inseparably linked with the socio, economical and cultural aspects of livelihoods. Action was taken through an integrated lake conservation programme, aiming to improve water quality. The most important lesson learnt is that awareness raising, education and stakeholder participation are essential.
The Weihe River plays a central role in Shaanxi. However, rapid economic development has created many problems, including increased water scarcity, pollution and regional ecological environment deterioration. As a response, the Weihe River Basin Integrated Management Plan was developed based on the principles and approaches of IWRM, with the participation of many sectors. The significance of this case is the promotion of public participation and gradual improvement of the market economy system.
With one of the lowest per capita freshwater resources in the world, China have been investing in and seeking new ideas and methods for improving both supply side and demand side management of water resources. This has included numerous experiments in “eco-compensation”. These experiences demonstrate that eco-compensation should be considered as a potential tool for Integrated River Basin Management to address financing shortfalls, identify management pitfalls, and convince key stakeholders to participate.
