In the former case it is intended to support the preparation of the Southern Africa Development Community SADC Agricultural Water Management for Food Security Project to be supported by the African Development Bank; and in the latter case it is intended to provide guidance for improving the effectiveness of current programs on micro-agricultural water management micro-AWM technologies implemented largely through NGOs. The methodology involved several activities: we designed a terms of reference and inventory format for obtaining country-level data through partners in Botswana, Lesotho, Malawi, Mozambique, Namibia, Swaziland, Tanzania, Zambia, and Zimbabwe. The partners interviewed key informants, reviewed local literature, and drew on their own experiences. We commissioned an in-depth impact assessment of treadle pumps in Malawi. We commissioned a study to carry out a more global literature review through the internet; and we carried out literature reviews and some field visits. Therefore, except for the Malawi treadle pump study, this is an extensive review, not an in-depth field work based assessment.

Part 1. The Issue Managing freshwater scarcities constitutes one of the great imperatives of governance almost everywhere in the world; local management is an indispensable component. Part 2. The Approaches Field research is examined in three approaches to local water management: small-scale water supply; wastewater treatment and reuse; and watershed management and irrigation.

Part 3. The Results: Propositions for Governance and Research Research results are addressed in a series of policy-relevant propositions aimed at decision-makers and at researchers in government, NGOs, communities, and beyond. Part 4. Recommendations Armed with the results presented in Part 3, specific recommendations are advanced for action that can be taken now in policy and research on local water management.

Part 5. Future Directions Future directions are plotted where progress can be accelerated in the science and in the conduct of local water management. When the International Development Research Centre IDRC was created in "to initiate, encourage, support and conduct research into the problems of the developing regions of the world," it immediately turned its attention, and some of its financial support, to water-related research.

Its early focus on supply technologies — such as inexpensive, simple-to-use handpumps — evolved to encompass water treatment and quality control, and has more recently broadened to questions of conservation and management. In doing so, IDRC has recognized that the water crisis is, as reflected in the summary report of the World Water Vision, "a crisis of managing water so badly that billions of people — and the environment — suffer badly.

This book synthesizes IDRC 's experience in local water management and presents a number of pointed, well-constructed recommendations for decision-makers, policy analysts, and researchers. From a review of the issue of freshwater supply and local water management, it explores examples of IDRC -supported field research in three broad, interconnected categories: small-scale water supply; wastewater treatment and reuse; and watershed management and irrigation.

Based on this research, a series of policy-relevant results are addressed in propositions aimed at decision-makers and researchers in government and beyond. To summarize:. Water management research can generate powerful consequences for politics and policy. Decision-makers make a big mistake when they dismiss small groups and small solutions, as they often do.

Distributing the costs and benefits of managing scarce water imposes hard choices. Making those choices, and giving them effect, requires institutional capacity. There is one iron rule for managing groundwater and aquifer supplies: assume the worst.

Successful local water management requires, and deserves, close collaboration between communities and governments. Hard data can pay rich dividends, even when outcomes disappoint. Local participation and local education increase the chances for successful and effective research.

Scaling up can generate welcome economies but intensify inequalities. Both effects need to be understood. Scaling up can succeed where institutions are capable of distributing the gains and the costs. Social and economic factors are always important in local water management. Sometimes they are paramount. Up, down, and sideways: local water management should always be informed by a three-part economic analysis. Policy and research should shift their focus from enlarging supplies of water to managing demand.

Policymaking should always start by accepting social custom and cultural norms as given, but not sacrosanct. Beware of generalizations, but share knowledge promptly. To achieve good government, and good science, evaluate in a transparent, participatory, and continuous manner. Finally, the book plots some future directions in which faster progress can be made in both the science and the conduct of local water management.

About a decade before the formation of the World Water Council and its vision exercise, IDRC had begun to place greater emphasis on participatory research and on community-based approaches to development.

Thus, it is entirely appropriate that this effort to bring its research on water directly to the attention of policy analysts and decision-makers should deal with local water management. Devolution of the power to manage water not just read metres and fix leaks will not come easily. The forces to maintain a top-down approach to water are well entrenched and serve many power elites. However, it will not come at all without a vision that indicates that, in the right circumstances, management by villages, communities, nongovernmental organizations, and water-users' associations may be the most appropriate way, not just to deliver water, but also to conserve its quality and its quantity.

If this publication expands recognition of that vision, it will have achieved its purpose. She is former President of the Population Council, a nonprofit, nongovernmental research organization established in Local and community-based water management seems to be an old idea whose time has come again.

For too many years, the role of local people has been, if not totally ignored, at least downplayed. Not that the developing world suffered from any failure to see water as a problem, or from the absence of water projects intended to alleviate scarcity.

Just the reverse. Scarcity of fresh and potable water was all too evident, and development projects abounded. National governments together with donor agencies and international financial institutions built new supply systems at all scales, from water pumps to massive dams.

And to some degree these technical fixes worked. Fresh water was brought to many households and many farms, and capacity was built in formal and informal institutions to respond to water scarcity. These are no small accomplishments, and, in the renewed enthusiasm for decentralization and local management, they should not be ignored. Despite the gains, however, the water projects of the first several development decades, by and large, fell short of their original promise.

Many reasons could be cited: principal among them is that technical solutions to water scarcity were designed to mould social and cultural factors rather than the other way around.

Only in the last decade or so have we come to recognize that, if efforts to improve the quantity or quality of water supply are to be successful, not only must they be technically sound and economically feasible, they must also deal directly with poverty alleviation, local empowerment, and ecological protection. As a pioneer in supporting research for development, IDRC rightfully joined the rest of the development community in devoting a part of its program budget to work on water supply.

For the first 20 years, the bulk of this work was technical: improved water pumps and rooftop water harvesting, for example. Gradually, studies began to include farmers or villagers in the research team and to consider options for "community-based" water security.

Until, by the mids, the emphasis was clearly on socioeconomic and behavioural aspects of water supply. Today, the focus of IDRC 's work has shifted to demand management and the devolution of water management to lower levels of government and communities. Recognizing that IDRC is not alone in this shift to a more institutionally focused approach, one purpose of this book is to share IDRC 's research results with other donors and other research institutions. Further, it recognizes that lessons learned from earlier work must inform and guide such projects.

This publication does just that, encapsulating what has been learned from 30 years of IDRC -supported research on the potential and limitations of local water management. Donors and research institutions, nongovernmental and community-based organizations, national government agencies and municipal governments — it is for decision-makers in these organizations that this publication is primarily intended. Many people contributed to the preparation of this book.

Thirty years of IDRC project staff and associated researchers in Canada and throughout the developing world are the ultimate source. Interns Sarah Wolfe and Tilly Shames assisted in the search and review of the IDRC water portfolio and helped me to glean indications of greater or lesser success with community involvement. Finally, John Hay, an Ottawa-based writer, took on much of the task of drafting the original text.

He and I interacted almost daily over a 3-month period of intense writing and review. I am very grateful for his contribution.

There have been too many assumptions and too few scientifically documented studies of local water management, and indeed other forms of local natural resource management. I hope that this synthesis for decision-makers will contribute to the learning process, and that it will stimulate the research and experimentation necessary to determine when community-based water management can be efficient, equitable, and sustainable.

Water scarcity threatens us all — menacing our well-being, jeopardizing our livelihoods, and sometimes endangering our lives. In more prosperous countries, water shortages curtail economic growth and diminish the quality of life. In poorer countries — especially among poor people — the scarcity of good water in adequate quantities already counts as a deadly affliction. It breeds sickness, blocks development, deepens inequalities of income and opportunity, and undermines the survival of entire societies.

The natural environment is everywhere imperiled by these scarcities, and by misguided attempts to overcome them. When water scarcity occurs at the boundaries of ethnicity or privilege, or at international borders, or between urban and rural communities, it can intensify the risk of conflict. It is fair to answer that water scarcities are hardly new to the human condition.

The Bible, the Koran, and other scriptures are rich with references to water — and to water-based conflict.

Dynamic management system of large-scale water conservancy project construction based on ArcGIS

Across the developing world, millions of people rely on the private sector for their daily water and sanitation needs. In the majority of cases, the providers of these essential services are not the large multinational corporations often associated with private participation in the water sector. They are local entrepreneurs operating on a small scale, who see selling water and sanitation services to the poor as market opportunities like any other. They are the markets of the unserved—people that public services have failed to provide for and for whom internationally recognized notions of improved services are out of reach. The paradox is that this large market is dominated by small, local enterprises. Domestic private entrepreneurs are increasingly being seen as part of the solution to increasing access to water and sanitation. Rural and periurban areas seem an unlikely place to start with private sector provision of water and sanitation services, but in many countries the lack of sustainable service in rural areas has been a driver of change. For example, in West

large scale water management projects

Don't have an account? Large-scale water projects to improve economic well-being or the environment often entail substantial uncertainty relating to gestation periods, cost, resettlement issues, adverse environmental impacts, and the potential for poor planning and execution as well as corruption. Because of widespread water scarcity, India has already invested a large amount of money in harnessing water resource projects. The government often uses cost-benefit analysis to assess large-scale projects, and, as knowledge of the technique grows, application of economic principles to small water projects has become more widespread. From small-scale projects like gray-water recycling at residential schools to analysis of the economic value of avoiding water-borne diseases, cost-benefit analysis can be used to inform decisions about how best to manage this precious commodity.

This article serves as a general reference for sustainable water supply systems. The scope remains global and macroscopic, though there may be regional differences depending on the water sources available in a particular setting. Sustainable water systems should provide adequate water quantity and appropriate water quality for a given need, without compromising the future ability to provide this capacity and quality. Water systems in the realm of sustainable development may not literally include the use of water, but include systems where the use of water has traditionally been required. Examples include waterless toilets and waterless car washes, whose use helps to alleviate water stress and secure a sustainable water supply. Accessing the sustainability features in water supply, that is to say, the three-fold goals of economic feasibility, social responsibility and environmental integrity, is linked to the purpose of water use. Sometimes, these purposes compete when resources are limited; for example, water needed to meet the demands of an increasingly urban population and those needs of rural agriculture.

In this article, we offer our insights in relation to a number of the delivery models that are typically considered by proponents of major water projects in Australia. The water sector is facing unprecedented challenges as climate change, population growth, ageing assets and competing interests increase pressure for limited resources. While a multi-pronged approach is required to address these risks, the upgrade of existing assets and the development of new infrastructure will be a vital part of this strategy.

Water scarcity already affects every continent. Around 1.

Hydropower (Large-scale)

Our expertise is unrivalled: we continuously offer our clients solutions driven by insight and innovation to meet challenges posed by changing water demand for domestic, agricultural and industrial uses. The importance of water in maintaining the well being of the earth and its inhabitants cannot be over emphasized. The current growth in world population would inevitably lead to an increased demand for water in food production, domestic and industrial purposes. Governments and agencies tasked with managing this resource are therefore faced with the challenge of water allocation for various uses. Our water resource management business core aim is to assist our clients to respond to these challenges. Water resources issues which we provide assistance for include local drinking water, large scale catchment management for water supply, irrigation water needs, hydropower schemes, flood and erosion control and protection of aquatic systems for wildlife. We have experience of providing our clients with efficient and sustainable solutions to water resources issues that are aimed at optimising natural flows in rivers and groundwater sources to meet the various competing needs for water.

Climate change has become one of the biggest, most complex challenges facing humankind in the 21stcentury, and water is at the heart of its impacts. This is particularly serious in arid regions like North Africa, where water resources are already being adversely affected by climate variability. In Morocco , due to a combination of population growth, economic development and a strong decline in precipitation, water resources are under more pressure. Water availability in Morocco has dropped from 3, m3per person per year in to 1, m3in , and forecasts are predicting it will further fall to m3in , below the United Nations' "absolute water scarcity" level.
