The young Himalayas have a serious problem of soil erosion and consequent sedimentation in river reaches downstream. The study revealed the high rates of sedimentation in Chenab basin and its effect on an existing reservoir. Correct estimation of sediment yield at any given point in space and time is of vital importance for water resources development and management. In the present study data of 17 to 27 years were used to develop statistically significant spatial models to estimate sediment yield in the Chenab basin (22,000 km2) using geomorphological, climatic and landuse parameters. The sediment yield was estimated for total and fine sediment for monsoon, premonsoon seasons and the year.

Premier d'une série, ce livre met en lumière l'analyse comparative des impacts négatifs des grands barrages sur les communautés riveraines en Afrique, au Moyen-Orient et en Asie. Ce livre est très intéressant pour les scientifiques en hydrologie, les ingénieurs civils et les environnementalistes qui travaillent sur les études sociales et économiques des grands barrages. Il a donc été important d'écrire une critique de ce livre.

Abstract The objective of this study is to assess the level of application of integrated water resources management (IWRM) in the lower Oueme valley. In order to achieve this, interviews with the actors' families allowed, on the basis of the survey on indicator 6.5.1 of the Sustainable Development Goals, to represent the degree of implementation of IWRM in the lower Oueme valley using a United Nations (UN) form. The results of this analysis reveal a low level of IWRM implementation with a score of 31 on a scale of 0–100. The weaknesses identified are mainly related to the lack of funding (score of 20/100) to cover all aspects of the development and management of water resources. Inadequate instruments or tools (score of 25/100) to enable decision-makers and users to make rational and informed decisions between different options and action measures, the unfavourable environment (score of 35/100) and finally weak institutional efficiency (score of 45/100), intersectoral coordination, and the involvement of various other stakeholders, are all evils that undermine the efficient management of water resources in the lower valley of Oueme.

This chapter provides a critical analysis and evaluation of the water issues relevant to Kenya's ASALs. This has particularly been centred on the current resource development and management, future resource demand as well as extent of its vulnerability to climate variability and change. The water development policy interventions have also been evaluated. The analysis has revealed that water resources are being utilized to satisfy a myriad of demands and that in-fact a water shortage already exists in these ASALs. A number of factors including population pressure, poor resource use and management and other socio-economic activities have been noted to increase the vulnerability of the available water to the impacts of climate change. A raft of recommendations for purposes of ensuring the sustainable utilization of this vital resource has therefore, been proposed.

The United Nations Millennium Declaration and resolutions at the 2002 World Summit on Sustainable Development give high priority to poverty reduction in international development agenda for the next decade and a half. It is now widely recognized that water resources development and management play a fundamental role in sustainable growth and poverty reduction. However, investments in water resources development, which were considered a high priority by governments and aid agencies for decades, have fallen drastically. The key question addressed in this paper is: Can water resources development reduce poverty? It examines the impacts of past investments on water resources development and management, (especially on irrigation), on poverty reduction. It is shown that past investments in irrigation development have made a significant contribution to alleviating poverty. In recent years investments made by private farmers in groundwater irrigation may have had a larger impact on livelihoods for poor people than the public investments in large-scale surface water irrigation systems. It is argued that there is not a single silver bullet to reduce poverty though water resources development or management. The best chance for lasting and sustainable impact on poverty is likely to be achieved through a combination of sustainable water resources development, combined with the development of appropriate pro-poor institutions and technologies.
