Water demand in southern Africa continues to rise, as urban areas expand and as agricultural water demand rises to meet the millennium development food security goals. Water resource availability in the northern Limpopo Basin has declined over the last 30 years, and will decline further under climate change. In this study, water resources modelling is used to quantify the effect of water resources strategies and climatic conditions on water resources availability. This is coupled with water balance modelling to evaluate the potential of alluvial aquifers, which form the beds of sand rivers.
The greatest benefit for the least impact comes from strategies providing for better land and soil/water management, such as changing from maize to small grains, production of livestock fodder and conservation agriculture. Small dams are a key resource to rural communities, and change to Multiple Use Systems through abstraction of water for irrigation has clear benefits locally. There is also great potential for the exploitation of alluvial aquifers for water supply. Better management of existing large dams, together with conjunctive use of alluvial groundwater and several reservoirs could increase productive use of water and significantly improve livelihoods without the construction of new reservoirs.

Описание: "Principles of Irrigation Engineering" is a 1913 work by F. T. Bioletti on the subject of irrigation methods, dealing with canals, dams, storage, water supple, dry land, and related law. Frederic Theodore Bioletti (1865 - 1939) was an English-born American vintner. He studied at the University of California, Berkeley from 1889 to 1900, where he worked with prominent soil scientist Professor E.W. Hilgard. His work with Hilgard on the fermentation of wines under different conditions were significant in helping California vintners to refine their wine production practices and improving the resulting wines. Bioletti was the first chair of the Department of Viticulture and Enology and founded the grape breeding program at the University of California Agricultural Experiment Station. This volume will appeal to those with an interest in irrigation techniques, and their history and development in particular. Many vintage books such as this are becoming increasingly scarce and expensive. It is with this in mind that we are republishing this volume now in an affordable, modern, high-quality edition complete with a specially-commissioned new biography of the author.

Описание: Arid and semi-arid regions can be defined as environments in which water is the limit- ing factor for bio-systems. Meeting the first demand, namely, supplying water to the agricultural communities and urban centers, involves, in many instances, the over-exploitation and misuse of nat- ural water resources.

Описание: The research has demonstrated the potential and the limitations of combining experimental fieldwork with modelling to optimize agricultural water productivity for Teff cultivation. Focusing on only experimental fieldwork is a single approach, and is hardly ever sufficient for achieving the best solutions to the current water management problems. New guidelines on using the combined effort of experimental work in the field to produce field experimental data and using models are clearly needed. It is to these needs as well as to the required increase of Teff production under water scarce conditions that this research has provided its main contribution.

Описание: Hydrology is a key influence on water security, environmental sustainability, agricultural production, energy, and transport, especially in unique environments such as arid regions and the tropics, where degradation issues on water and land can threaten the livelihoods of poor communities. With implications in urbanization, landscape architecture, and sanitation, enhancing the practice of water use, management, and planning is imperative for the sustainable development of these regions. Hydrology and Water Resources Management in Arid, Semi-Arid, and Tropical Region is an essential research publication that seeks to improve scientific understanding and sharing of data in hydrology and integrated water resources management of arid, semi-arid, and tropical regions in order to enhance water governance and alleviate reduction in the vulnerability of water resources systems to global changes. Featuring a wide range of topics such as hydrometeorology, sustainable development, and climate change, this book is ideal for researchers, technology developers, academicians, policymakers, government officials, and students.
