Download Simulating the hydrology of small coastal ecosystems in conditions of limited data Book in PDF, ePub and Kindle
The impacts of water resources and irrigation development need to be quantified in order to understand the environmental costs of such development activities. Complex data-intensive simulation methods are normally used for this purpose in the developed world. However, lack of reliable data prohibits the use of such models in developing countries where it is more practical to apply models with less data requirements. The report illustrates three applications of simple and pragmatic simulation models to small coastal water bodies in Sri Lanka and South Africa.

Download The Ocean and Cryosphere in a Changing Climate Book in PDF, ePub and Kindle
The Intergovernmental Panel on Climate Change (IPCC) is the leading international body for assessing the science related to climate change. It provides policymakers with regular assessments of the scientific basis of human-induced climate change, its impacts and future risks, and options for adaptation and mitigation. This IPCC Special Report on the Ocean and Cryosphere in a Changing Climate is the most comprehensive and up-to-date assessment of the observed and projected changes to the ocean and cryosphere and their associated impacts and risks, with a focus on resilience, risk management response options, and adaptation measures, considering both their potential and limitations. It brings together knowledge on physical and biogeochemical changes, the interplay with ecosystem changes, and the implications for human communities. It serves policymakers, decision makers, stakeholders, and all interested parties with unbiased, up-to-date, policy-relevant information. This title is also available as Open Access on Cambridge Core.

Download An assessment of small-scale users' inclusion in large-scale water user associations of South Africa Book in PDF, ePub and Kindle
The management of water resources is being transformed in South Africa. All water users, especially the small-scale ones, are now invited to participate in this movement. This report reviews the process of inclusion of small-scale users in the new large-scale Water User Associations (WUA).Considering the difficulties encountered in this process, this report also recommend external monitoring after the transformation of an Irrigation Board into a WUA. This method may also facilitate assessment of the inclusion of small-scale users into catchment management agencies, and water resource management organizations.

Download The Use of Remote Sensing Data for Drought Assessment and Monitoring in Southwest Asia Book in PDF, ePub and Kindle
This report describes the development of the near real-time drought monitoring and reporting system for the region, which currently includes Afghanistan, Pakistan and western parts of India. The system is based on drought-related indices derived from high-resolution remote-sensing data (MODIS). The unique feature of the study is the development of regression relationships between drought-related indices obtained from MODIS and AVHRR data, which have different pixel-resolution and optical characteristics. The goal is to make the system available, via Internet, to all stakeholders in the region.

Download Planning for environmental water allocations: An example of hydrology-based assessment in the East Rapti River, Nepal Book in PDF, ePub and Kindle
Although the protection of the aquatic environment is high on the world water resources agenda, most developing countries still lack the technical and institutional capacity to establish environmental water allocation practices and policies. The existing methods of assessment of environmental water allocations are either complex and resource-intensive or not tailor-made for the specific conditions of a particular country or region. To promote emerging concepts of environmental flow assessment and management, it is important to change the dominant perception that environmental demand is the least important and create awareness among responsible authorities about existing methodologies and processes that should be followed. This report presents some of these approaches and illustrates their applicability in the specific context of the East Rapti River basin, which features one of the main tourist attractions of Nepal, the Chitwan National Park.

Download Working wetlands: classifying wetland potential for agriculture Book in PDF, ePub and Kindle
This paper reports on a form of multi-criteria analysis that provides a formal approach for evaluating the suitability of a wetland for specific agricultural uses, and ensures that explicit consideration is given to the possible consequences of such utilization. The method is based on a hybrid of ideas taken from concepts and methodologies related to: environmental flow assessments, land suitability classification and the hazard evaluation procedures used in the design of dams. The approach, which elaborates the idea of working wetlands, is generic, though the examples presented are for case studies from southern Africa.

Download Economics and politics of water resources development: Uda Walawe Irrigation Project, Sri Lanka Book in PDF, ePub and Kindle
The Uda Walawe Irrigation and Resettlement Project (UWIRP) located in the Southern dry zone of Sri Lanka was initiated in the early 1950s. The original plan for the UWIRP was a highly ambitious social, economic and physical engineering project aimed at creating a modern, profitable agriculture sector. This report examines the history of water resources development and investment decisions for the UWIRP over a period of 50 years and uncovers underlying processes that shaped the evolution of the project and highlights the limitation of viewing development as a mere set of technical and social engineering endeavors.

Download Strategies for the Management of Conjunctive Use of Surface Water and Groundwater Resources in Semi-arid Areas Book in PDF, ePub and Kindle
Due to inadequate rainfall, groundwater has acquired a vital role in the development of Pakistan's agricultural economy. However, a lack of awareness concerning the use of groundwater, either by itself or combined with canal water, has added large amounts of salt to the soil. As a result, large tracts of irrigated lands are already salinized, while many others are under threat. This report presents the results of a modeling study carried out to evaluate the long-term effects of a different quality of irrigation water on root zone salinity. The simulations were performed for the Rechna Doab (sub basin of the Indus Basin) in Pakistan, by using 15 years of actual rainfall and climatic data.

Download Spatial Variation in Water Supply and Demand Across River Basins of India Book in PDF, ePub and Kindle
India is a large country with regional differences in per-capita water supply and demand. Attempts to describe the water situation in India at a national level are often misleading due to the tremendous diversity in the water situation across the country. This Report analyzes the spatial variation of water supply and demand across river basins in India. The study identifies basins that are water-scarce because of inadequate water availability to meet the effective demand. It also identifies issues that are important for estimating the future water demand and for the formation of policy for future water-resources development and management.
