Lessons From Two Long-term Hydrological Studies in Kenya and Sri Lanka
Mungai, D. N.
The rate and characteristics of land use change in tropical watersheds due to changing demographic, economic and policy factors have important consequences for catchment health and environmental services. Few tropical watershed studies have lasted long enough to facilitate a credible analysis of the long-term effects of land use change on the environmental services provided by watersheds. This paper examines the driving forces and patterns of historical land use change in two long-term watershed studies in Kenya and Sri Lanka and their hydrological impacts.

Les bassins hydrographiques internationaux
Luzi, Samuel
"Alors que le discours sur la « gestion de l'eau » privilégiait autrefois une approche axée sur l'ingénierie, il adopte désormais une perspective plus globale qui privilégie la protection de l'environnement, l'efficacité, ainsi que les aspects politiques et institutionnels de la gestion et de la planification intégrée et coopérative de l'eau. C'est la crainte d'une « guerre de l'eau » qui a permis d'accélérer l'intégration de la gestion de l'eau dans les bassins versants partagés ; les questions hydriques figurent désormais à l'ordre du jour de décideurs haut placés et d'organisations internationales spécialistes des questions de sécurité, et des cadres spécifiques ont été créés pour gérer les relations conflictuelles entre groupes d'opérateurs à différents niveaux."

GIS based watershed classification in Lao P.D.R
Heinimann, Andreas
The Mekong River Commission (MRC) elaborated a spatial explicit Watershed Classification (WSC) for the Lower Mekong Basin. Based on topographic factors derived from a high-resolution Digital Terrain Model, five watershed classes are calculated, giving indication about the sensitivity to resource degradation by soil erosion. An analysis of the WSC in conjunction with forest cover data revealed that the more the 37% of Laos can be considered as critical with regard to degradation risk by soil erosion. The WSC allows spatial priority setting for watershed management and generally supports informed decision making on reconnaissance level. In the conclusions the article focuses on general considerations when GIS techniques are used for spatial decision support in a development context.

Assessment of water quality problems and mitigation potentials by using material flow analysis
Schaffner, Monika
"Material flow analysis (MFA) is a promising tool for river water quality management. Based on orders-ofmagnitude estimations, the approach provides an overview of pollution problems and their dimensions in a river system, allowing to identify key sources and pathways of pollution, and to evaluate mitigation priorities. The current study aims at investigating MFA to assess river water quality problems and mitigation measures in developing countries, based on a case-study carried out in the Tha Chin River Basin (TRB), Thailand."

Patterns of Land Cover Change in the Lower Mekong Basin
Heinimann, Andreas
PhD Thesis, University of Bern, Switzerland "The present study seeks to generate a comparable information and knowledge base about land cover change on a mesoscale level for the entire Lower Mekong Basin. Such information is crucial to both informed decision making and the transboundary negotiations on the use and protection of the shared natural resources in regional bodies such as the Mekong River Commission. It may form the basis for achieving a common understanding regarding resource management in the Basin despite diverging national interests.
