Problems of unsustainable watershed use in the Mediterranean areas (overgrazing, forest degradation and clearing, soil erosion, fires, etc.) often result from the reduced profitability of traditional land use systems, lack of clearly defined property rights, insufficient enforcement of existing rules, and lack of adequate economic instruments.

Numerous pilot studies and case studies in the Volta Basin have evaluated practices, methods, and tools that could prove beneficial to others, both within the basin and outside of it. However, the question whether an intervention successfully applied in one location has a reasonable chance of success at any other location remains extremely difficult to answer.

Poyang Lake is the largest freshwater lake in China covering 3800 km2 during the summer wet season. It drains into the Changjiang (Yangtze River) at its northern end through a narrow outlet. During the last half of the twentieth century (1949–1999) average annual maximum stage and number of severe flood events in China's Poyang Lake region increased significantly. There are two primary causes for this trend. One was increasing Changjiang stage, which is the most important determinant of Poyang Lake stage.

The Limpopo Basin is prone to frequent droughts and short season rainfall making agricultural production a very risky enterprise. The need assist to farmers and rural communities to optimize the utilization of low rainwater and existing SWI to boost agricultural productivity, standard of living and reduce poverty.

The Coordination and Change project of the Limpopo Basin Development Challenge (L5) is designed to help the four BDC projects conduct quality, coherent, and problem oriented research to contribute to beneficial change in the basin. L5 will develop and implement a communication and knowledge management strategy to facilitate integration of the major activities; capture, store and distribute relevant data; and identify and address capacity building needs—both within the BDC team—and among key external stakeholders.

En Ecuador, la confrontación entre el gobierno y el movimiento indígena en torno a la nueva Ley de Aguas terminó con la suspensión de la propuesta y el bloque de diversas iniciativas.

The dry areas face severe challenges to sustainable development. The biggest challenges – food insecurity, water scarcity, land degradation, and climate change – are closely inter-related. The effects of climate change will be felt globally, but the dry areas will be particularly hard hit. Climate change will exacerbate water scarcity, rainfall variability, and the decline in the natural resource base, and thus could have a profound impact on food security.

The Yellow River Basin (YRB) Focal Project set out to study water poverty, water

availability and access, water productivity, and water and related institutions in the

Yellow River basin to develop and rank a series of high-priority interventions aimed at

increasing water and food security for the poor, while maintaining environmental

sustainability. The YBFP identified complex relations between water and poverty in the

YRB; identified streamflow declines in the basin despite predicted higher rainfall;

This study aims are to compare the characteristics of the Greek Polis of Metaponto and Poseidonia water collecting and distribution systems. And also, display the differences and similarities between the water management systems used, as to better understand the criteria developed to orientate the place of settlements and also of certain urban characteristics chosen by the Greeks, between the VIII and IV centuries B.C.

El programa TERRENA (TERritorio Y REcursos NAturales), que Ingeniería Sin Fronteras desarrolla en la cuenca alta de Río Viejo (Nicaragua), tiene como objetivo reducir la vulnerabilidad en las áreas rurales empobrecidas, mediante la gestión integral y sostenible de recursos hídricos y del territorio, incluyendo la prevención y mitigación de riesgos de desastres, todo ello con un enfoque de cuenca hidrográfica.
