Strategies for the Management of Conjunctive Use of Surface Water and Groundwater Resources in Semi-arid Areas by Asad Sarwar Qureshi,Hugh Turral,Ilyas Masih Pdf

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.

Understanding Hydrological Variability for Improved Water Management in the Semi-Arid Karkheh Basin, Iran by Ilyas Masih Pdf

This study provides a hydrology based assessment of (surface) water resources and its continuum of variability and change at different spatio-temporal scales in the semi‐arid Karkheh Basin, Iran, where water is scarce, competition among users is high and massive water resources development is under way. The study reveals that the ongoing allocation planning is not sustainable and essentially requires reformulation, with consideration of spatio‐temporal variability and observed trends in the streamflows regarding flood intensification and decline in low flows. The development of innovative methods for quantification of the hydrological fluxes (i.e., regionalization of model parameters based on similarity of the flow duration curve and the use of areal precipitation input in the hydrological modeling) helped better understanding and modeling the basin hydrology. The investigation of scenarios for upgrading rain-fed areas to irrigated agriculture, using SWAT, recommends the promotion of in-situ soil and water conservation techniques. Conversion of rain-fed areas to irrigation causes significant reduction in the downstream flows, and requires additional considerations such as less development in the upper catchments, practicing supplementary irrigation and developing water storage. The knowledge generated is instructive for hydrological assessment and its use in water resources planning and management in the river basin context.

Understanding Water in a Dry Environment by Ian Simmers Pdf

In order to provide water security in the twenty-first century, there is universal agreement that a continuation of current policies and extrapolation of trends is not an option. Also clear is that from both water supply and development perspectives, the world's arid and semi-arid regions are those currently and potentially experiencing the highest water stresses. One third of the world's land surface is classified as arid or semi-arid, and about half of all countries are directly affected in some way by problems of aridity. The hydrology of arid and semi-arid areas is also known to be substantially different from that in more humid regions. It is therefore essential that investigation methods appropriate to the former are developed and applied, and that strategies for arid and semi-arid region water resources development recognise the principal characteristics of in-situ hydrological processes.

Hydrology and Water Resources Management in Arid, Semi-Arid, and Tropical Regions by Ondieki, Christopher Misati,Kitheka, Johnson Utu Pdf

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 Regions 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.

Beyond Scarcity by World Bank Pdf

Water has always been a source of risks and opportunities in the Middle East and North Africa. Yet rapidly changing socioeconomic, political, and environmental conditions make water security a different, and more urgent, challenge than ever before. This report shows that achieving water security means much more than coping with water scarcity. It means managing water resources in a sustainable, efficient, and equitable way. It also involves delivering water services reliably and affordably, to reinforce relationships between service providers and water users and contribute to a renewed social contract. Water security also entails mitigating water-related risks such as floods and droughts. Water security is an urgent target, but it is also a target within reach. A host of potential solutions to the region’s water management challenges exist. To make these solutions work, clear incentives are needed to change the way water is managed, conserved, and allocated. To make these solutions work, countries in the region will also need to better engage water users, civil society, and youth. The failure of policies to address water challenges can have severe impacts on people’s well-being and political stability. The strategic question for the region is whether countries will act with foresight and resolve to strengthen water security, or whether they will wait to react to the inevitable disruptions of water crises.

Water Resources Policies in South Asia by Anjal Prakash,Sreoshi Singh,C. G. Goodrich,S. Janakarajan Pdf

Falling or stagnant agricultural growth, increasing dependence on groundwater, climate variability, swift industrialization, and unplanned and unregulated urbanization in South Asia have spawned a variety of challenges for water resources governance, management and use: groundwater overdraft; insufficient, ill-managed and poor-quality freshwater supply vis-à-vis escalating demand; and water pollution. Water policies in each of the South Asian countries thus call for a more holistic understanding for the efficient management, equitable distribution and sustainable use of this scarce resource. Analyzing the economic, demographic and ideological context in which water policies are framed and implemented, this book argues for an integrated framework in formulating and implementing water policies in South Asia. It also highlights some common missing links in the national policies: problems of techno-centric and blueprint approach to water management, growing influence of international donor agencies and inadequate concern for issues such as equity, sustainability, gender sensitivity, accountability, regional diversity in property rights regimes and water management practices, and regional conflicts over water access. The innovative and nuanced knowledge on water resources produced from detailed case studies in India, Bangladesh, Bhutan, Nepal, Pakistan and Sri Lanka will be useful for professionals, academics, policymakers and activists as well as those in development studies, environmental studies, natural resource management and public administration.
