Water policy is an important topic on
the agenda of the international community, and efficiency
and equity in the allocation of water have emerged as
important factors to be considered. Water pricing can be
used to mitigate both the quantity and quality dimensions of
water scarcity. This paper reviews partial equilibrium
models and general equilibrium models that are relevant to
irrigation water management issues. The most widely

Cooperative management, and development
of Africa's international rivers holds real promise for
greater sustainability, and productivity of the
continent's increasingly scarce water resources, and
fragile environment. Moreover, the potential benefits of
cooperative water resources management, can serve as
catalysts for broader regional cooperation, economic
integration, and development - and even conflict prevention.

This paper deals with economic rents
arising from the development of hydroelectric generation on
international watercourses. The paper briefly defines the
concept of economic rent and its application to
hydroelectric developments. It explores two areas of
precedents that shows how the concept could be applied in
developments on international watercourses. First, it looks
at international law on the ownership and rights of use of

The mekong is a major transboundary central to the lives of the people in the southeast asia,Since 2006 contested plans have emerged for up to eleven dams on the lower mainstream,with the first project-the Xayaboury dam-under contruction in the northerm laos since 2010 the paper explores how uncertainty shaps transboundary water governance such as the politics of scale and knowledge

VFI has been working in Cambodia for 7 years now. Our ECOSORN Project aims to provide water supply and sanitation facilities, and to improve sustainability by introducing appropriate technologies for villagers. 



We operate this project in 3 provinces, 14 districts, 36 communes, 78 villages in the most remote parts of Battambang, Banteay Meanchey and Siem Reap Provinces. Our project goal is to build 6,000 latrines; 110 water wells; 1,000 water storage jars; and 5 large ponds

The Asia and Pacific region has witnessed a remarkable transition in the past 2 decades. From 1990 to 2012, more than 1 billion people in Asia and the Pacific were lifted out of extreme poverty. The region also witnessed rapid economic growth, which is expected to remain stable at a growth rate of about 5.7% for the next 2 years.

“Water is the lifeblood of the people of Afghanistan, not just for living but also for the economy, which has traditionally been dominated by agriculture.” Nearly “80% of Afghanistan’s population derive their livelihood from the agriculture sector.” And, agriculture remains one of Afghanistan’s principal growth sectors.

During the last few years, the donor community has increased its efforts to reduce the large amounts of fish lost in the distribution chain in artisanal fishery, an endeavour that ought to be welcomed in principle. However, focusing on one single solution, the development of an expensive cool chain and the supply of fresh or frozen fish, represents a massive interference with the traditional processing and distribution channels, with women being the main losers. Our author calls for more foresight in international co-operation.

Experts agree that the rising demand for fish for human consumption cannot be met without a major expansion and sustainable intensification of aquaculture. Our WorldFish authors describe the areas in which research plays a particularly important role in this context.

Mauritania’s coastal waters are among the world’s richest fishing grounds. However, just as in many other countries around the globe, the sustainable use of this resource is under threat from illegal fishing and overfishing. KfW contributes to protecting the valuable fishing grounds with the aid of modern surveillance systems and rigorous conservation and species protection measures.

Riparian ecosystems are valuable to the ecological and human communities that depend on them. Over the past century, they have been subject to shifting management practices to maximize human use and ecosystem services, creating a complex relationship between water policy, management, and the natural ecosystem. This has necessitated research on the spatial and temporal dynamics of riparian vegetation change. The San Acacia Reach of the Middle Rio Grande has experienced multiple management and river flow fluctuations, resulting in threats to its riparian and aquatic ecosystems.

Matters of environmental migration are frequently looked at from a humanitarian perspective.1 This policy brief will instead look at it with a lens focusing on land issues. The question of environmental migration is inevitably linked to the question of land for several reasons. First, climate and environmental change trigger and accelerate the loss of land due to sea-level rise, coastal erosion, landslides and other forms of land degradation.
