This report presents the assessment of Lakes Turkana, Tanganyika, Victoria and Malawi – the largest of the East African Rift Valley Lakes and among the oldest lakes in the world.

This report presents the assessment of the GIWA Eastern Equatorial Pacific region, which includes parts of Mexico, Guatemala, Honduras, Nicaragua, Costa Rica, Panama and Colombia.

In this study the vulnerability of water resources to environmental change is assessed on a river/lake/groundwater basin scale for the Southern, Eastern, Western & Northern African Regions.

Groundwater pollution is a serious problem throughout the African continent. While this is not surprising, very little attention has been paid to the problem. Information on this threat to Africa's future is therefore not readily available.

In Africa, most rivers, freshwater lakes, and aquifers are shared by two or more countries. The diversity of politial, social, and economic structures and organizations among African countries and the varied temporal preciptation and distribution of water on the continent make hydropolitical setting very complex and prone to vulnerability.

This report presents the GIWA assessment of the Mekong River region which comprises parts of Cambodia, China, Lao PDR, Myanmar, Thailand and Vietnam.

L’étude entend appuyer la réflexion permanente sur la meilleure façon d’aborder les enjeux soulevés par l’interface entre les droits à l’eau et au foncier, aussi bien qu’un processus à plus long terme de débat politique et d’échange d’expériences autour de ces questions au Sahel. Ce processus (le "Groupe d’apprentissage de la gouvernance de l’eau au Sahel") implique tout un éventail d’acteurs qui cherchent à améliorer l’accès à l’eau - décideurs, agents du développement, associations d’usagers et de producteurs, chefs de communauté et autres acteurs de la société civile – et il se penchera sur des façons pratiques de tenir compte des enjeux fonciers dans les programmes hydrauliques. L’étude se concentre sur deux domaines clés de l’interface entre les droits au foncier et à l’eau : l'irrigation et les points d’eau pastoraux. Elle explore également certaines questions clés concernant les liens entre le droit à l’eau, au foncier et aux autres ressources naturelles dans le contexte des zones humides de haute valeur. L’étude se concentre sur le Sahel, en particulier le Sénégal, le Mali, le Burkina Faso et le Niger. Les éléments de preuve et documents pertinents issus d’autres pays sahéliens sont utilisés pour éclairer encore la perspective. Il est également fait référence aux développements intervenus dans d’autres pays d’Afrique sub-saharienne, afin de replacer l’analyse sahélienne dans un contexte plus vaste.

While large private water companies grab the headlines, it is more often small private vendors that bring water to the urban poor in Africa, Asia and Latin America. This working paper looks at how water-vending systems operate, how effective they are in meeting the needs of the urban poor, and how this effectiveness might be improved. The paper concentrates on the small-scale and informal vendors, most of whom work independently with very little capital. Nevertheless, they display enormous diversity and flexibility, and are adept at responding to the needs of all but the very poorest households.

Half the world's people live in urban areas, and roughly a third of these live in desperate poverty without access to basic amenities. Taking on the themes of the UN-HABITAT's Water and Sanitation in the Worlds Cities (2003), this new volume focuses on the deficiences in the provision of water and sanitation where most of the population of the developing world live : in towns and small cities.
