There are many options for enhancing food production from fish in managed aquatic systems.The most appropriate technology, however, will vary from place to place, and the conditions under which one technology is prefered over another are still not well defined.
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 paper applies the principles of water-use accounts, developed in the first of the
series, to the Indus River basin in South Asia. The Indus Basin covers 3 countries, rises
in the Tibetan plateau in the vicinity of Lake Mansarovar in China. Irrigated agriculture
in the Basin is extensive with the construction of dams, barrages, and link canals to
distribute water, with modern engineering to support irrigation starting as early as the
mid 1800s.
Net runoff is about 10% of total precipitation. Irrigated agriculture covers 20% of
This paper applies the principles of water-use accounts, developed in the first of the series, to the Mekong River basin in Southeast Asia. The Mekong Basin covers six
countries, the River rises in China, but there are substantial downstream tributaries
from Thailand, Laos, Cambodia, and Vietnam, and from a small area in Myanmar. A
unique feature is the reverse flow from the Mekong to the Tonle Sap via the Tonle Sap
River at the height of the wet season flow and its ebb as the river levels fall.
This paper applies the principles of water-use accounts, developed in the first of the
series, to the Yellow River basin in China. The Yellow River rises in the Bayan Har
Mountains in Qinghai Province in western China, and empties into the Bohai Sea. A
unique feature of the river is the large amount of silt it carries.
Net runoff is about 14% of total precipitation. Forest and woodland cover 9% of the
basin and use about 15% of the precipitation. Grassland covers much of the upper part
This project examined the linkages between population and demand for food and water. Cambodia, in general, and Pursat Province in particular, have a complex and interesting mosaic of demographic attributes and development issues. The Tonle Sap basin and Pursat catchment possess the country’s largest potential water resources.
This working paper examines population growth in Pursat and its potential impact on food demand and land and water resources in a systematic and integrated manner. The main purpose of the paper is to kick-start a policy debate on population dynamics and food and water security in Pursat. The paper provides background information, observations and empirical analysis of resource demand (real or perceived) associated with population growth and policy decisions related to food and water security.
Most African countries underwent water legislation reform since the 1990s, through
which existing plural legal systems were changed into nation-wide permit systems, in
which the state acts as custodian of the nation’s water resources. Although globally
heralded as the best way to manage water resources within the broader context of
Integrated Water Resource Management, this project examines the problematic
implications of the new laws for the majority of the rural and peri-urban poor. Since time
