High elevation páramo (wetland) ecosystems in the Andes are important water sources for local communities and downstream agricultural and urban users. These headwater catchments, however, are often impacted by human activities (eg agricultural production) that affect both stream water quality and flow. Knowledge about water availability, quality, and use is essential for effective management but is often lacking, particularly in smaller mountain communities.

This paper applies the principles of water-use accounts, developed in the first of the

series, to the São Francisco basin in South America. The São Francisco Basin lies wholly

within Brazil. There are several major dams and wetlands in the Basin.

Net runoff is about 16% of total precipitation. Grassland is the most extensive land use,

covering 59% of the Basin and uses 48% of the water. Rainfed agriculture covers 23%

of the basin, but uses 14% of the water in the Basin. Forest and woodland cover 16% of

This paper applies the principles of water-use accounts, developed in the first of the series, to the Nile River basin in Northeast Africa. The Nile and its tributaries flow though nine countries. The White Nile flows though Uganda, Sudan, and Egypt. The Blue Nile starts in Ethiopia. Zaire, Kenya, Tanzanian, Rwanda, and Burundi all have tributaries, which flow into the Nile or into Lake Victoria.

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 paper apples the principle of west –use accounts, developed in the first of the series, to the Volta River in West Africa. The Volta Basin covers six countries, with 85% of its area in Ghana and Burkina Faso.

Runoff in all three tributaries increases from 2-7% in the drier north to 12-26 % in the higher – rainfall south. Grassland is the dominant land use throughout Basin ranging from 76% of the Delta catchment in the south to 98% of the Arly catchment with corresponding water use of 55% and 92% of water used in each.

In Tanzania like in other parts of the global South, in the name of 'development' and 'poverty eradication' vast tracts of land have been earmarked by the government to be developed by investors for different commercial agricultural projects, giving rise to the contested land grab phenomenon. In parallel, Integrated Water Resources Management (IWRM) has been promoted in the country and globally as the governance framework that seeks to manage water resources in an efficient, equitable and sustainable manner.

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 interactive poster was presented at the 2013 Stockholm World Water Week. It describes the results of a 'public good game' carried out with farmers in the polder zones of coastal Bangladesh in order to understand determinants of contributions to maintain a public good.

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.
