DOWNLOAD EBOOKThis study attempts to re-frame the current thinking on groundwater development and the implications for food security. Groundwater is important in agriculture as it provides a reliable fallback when rainfeeding fails. It is therefore instrumental in managing risk and optimizing food production. However accessing groundwater has become habit and turned to dependency. Resources limits on many key aquifers have been exceeded and competition for groundwater has become intense. This study highlights the role of adaptive strategies in dealing with aquifer management and indicates directions of research and management.

DOWNLOAD EBOOKThis book constitutes the refereed post-conference proceedings of the 7th International Conference on Advancement of Science and Technology, ICAST 2019, which took place in Bahir Dar, Ethiopia, in August 2019. The 76 revised full papers were carefully reviewed and selected from more than 150 submissions. The papers present economic and technologic developments in modern societies in five tracks: agro-processing industries for sustainable development, water resources and environmental engineering, recent advances in electrical, electronics and computing technologies, product design, manufacturing and systems organization, and material science and engineering.

DOWNLOAD EBOOKMore than a billion people cannot get safe drinking water; half the world's population does not have adequate sanitation; within a generation over three billion will be suffering from water stress. This text analyzes the issues in this crisis of management and shows how water can be used effectively and productively. The key to sustainable water resources is an integrated approach. The authors assert that careful planning and concerted action can make the fundamental changes needed and that the implications of not dealing with the crisis are immense. The book comes with a CD ROM containing background research and scenarios.

DOWNLOAD EBOOKClimate change not only involves rising temperatures but it can also alter the hydro-meteorological parameters of a region and the corresponding changes emerging in the various biotic or abiotic environmental features. One of the results of climate change has been the impact on the sediment yield and its transport. These changes have implications for various other environmental components, particularly soils, water bodies, water quality, land productivity, sedimentation processes, glacier dynamics, and risk management strategies to name a few. This volume provides an overview of the fundamental processes and impacts of climate change on river basin management and examines issues related to soil erosion, sedimentation, and contaminants, as well as rainfall-runoff modeling and flood mitigation strategies. It also includes coverage of climate change fundamentals as well as chapters on related global treaties and policies.

DOWNLOAD EBOOKThis study was undertaken to analyze farmers’ adaption to water scarcity in the command area of a secondary canal in the Nile Delta of Egypt. The results revealed that farmers’ responses were driven by a multiplicity of factors, beyond water scarcity or profit maximization. These additional factors include food security of the family, risk management, social capital and history of farmers, and most unexpectedly the collective dimension of crop choice. The findings of this study expose the limitations of projects, modeling exercises or policy recommendations that are too often based on the oversimplified view of profit maximization as the basis of farming system dynamics.

DOWNLOAD EBOOKManaging water resources is one of the most pressing challenges of our times - fundamental to how we feed 2 billion more people in coming decades, eliminate poverty, and reverse ecosystem degradation. This Comprehensive Assessment of Water Management in Agriculture, involving more than 700 leading specialists, evaluates current thinking on water and its interplay with agriculture to help chart the way forward. It offers actions for water management and water policy - to ensure more equitable and effective use. This assessment describes key water-food-environment trends that influence our lives today and uses scenarios to explore the consequences of a range of potential investments. It aims to inform investors and policymakers about water and food choices in light of such crucial influences as poverty, ecosystems, governance, and productivity. It covers rainfed agriculture, irrigation, groundwater, marginal-quality water, fisheries, livestock, rice, land, and river basins. Ample tables, graphs, and references make this an invaluable work for practitioners, academics, researchers, and policymakers in water management, agriculture, conservation, and development.

DOWNLOAD EBOOKIn this study, satellite remote sensing and geographic information system (GIS) techniques were used to analyze the agricultural performance and sustainability of the Bhakra Irrigation System in India. The results demonstrate the synergy possible from applying satellite remote sensing and GIS to evaluate trends in rising water tables and salinity, which are two important threats to the sustainability of irrigation systems, and the cost-effectiveness of these techniques as diagnostic tools for irrigation system improvement.
