This document provides an overview of how water resource software’s (WRS) are used to manage water resources issues, criteria for WRS selection, and a high level review of WRS currently available that central and state governments of India can use for water management. The water resource issues covered include water allocation and planning, flood management, groundwater management, conjunctive use, water quality, and sediment transport.

This report, developed for policy makers and sector development partners, highlights the manner in which the domestic private sector is successfully participating in the delivery of water and sanitation services in Niger. It outlines the factors for success as well as the challenges that need to be addressed to harness private sector resources and motivation for improved and sustainable services.There is a need to further strengthen the capacities of various rural water supply stakeholders, particularly communes, which contract and supervise the work of the operators. The capacities of operators and users’ associations also need to be developed to pursue ensure the operational sustainability of the systems.The technical assistance (TA) described in this Note has, over the past five years, supported the sector’s stakeholders’ efforts to work in synergy to foster the participation of domestic private entities in the management of rural water supply systems (RWSSs).The purpose of the TA hasbeen to ensure improved operational policy applicationof the PPP frameworks in the context of water supplyand urban sanitation in rural and small towns , which hasnot evolved much over time in relation to urban waterservices. The TA program consisted of training activities,market assessments, and options development studiesto inform decision-making and consensus-building ofdifferent stakeholders on resolving some challenges facingthese subsectors.Opportunities exist for the Government to promote the emerging domestic private operators with a view to raising their level of professionalism for better service delivery.

Building effective cooperation on transboundary waters is always a lengthy and complex journey. Embracing cooperation is no simple task for a nation state, not least because of the perceived costs of the erosion of sovereignty, however small that erosion might be. While there are many examples of where cooperation is non-existent or weak, there are also examples – across countries and across time – of effective cooperation. This essay examines these issues through a practitioner’s lens to draw a few lessons from experience on why countries cooperate and how cooperation can be achieved.

The Nile Story is one of immense challenges and remarkable achievements for the economic development of the region. It begins in 1999, when the ministers in charge of water affairs in the Nile countries agreed to form the Nile Basin Initiative (NBI). Between 2003 and 2015, the Nile Basin Trust Fund (NBTF) supported and coordinated cooperative work in the region, which has been delivered mainly through the NBI. This book, commissioned by the World Bank on the closure of the NBTF, captures some insights to this 15 year story, the role of the NBI, and how its many achievements have been made along the way.

We consider an application of pooled stepped chutes where the transport in each pooled step is described by the shallow--water equations. Such systems can be found for example at large dams in order to release overflowing water. We analyze the mathematical conditions coupling the flows between different chutes taken from the engineering literature. We present the solution to a Riemann problem in the large and also a well--posedness result for the coupled problem. We finally report on some numerical experiments., 17 pages, 31 figures

This report presents the water and climate adaptation plan (WATCAP) developed for the Sava river basin (SRB) as result of a study undertaken by the World Bank. The WATCAP is intended to help to bridge the gap between the climate change predictions for the SRB and the decision makers in current and planned water management investment projects that will be affected by changing climate trends. The purpose of the report is to: (i) assist stakeholders and decision makers in assessing and planning for the risks generated by climate change impacts on water resources; (ii) provide a basis for future plans and studies of adaptation to climate change impacts in the SRB; and (iii) stimulate cooperation and debate across the basin toward additional and more detailed studies on climate change impacts at the regional and basin scale. The SRB is projected to experience small increases in water use by the public water supply, industry, energy, and agricultural and irrigation sectors. However, it is widely expected that new hydropower plants (HPPs) will be constructed in the near future, making energy (primarily through hydropower) the most important water use in the SRB.

Professionalization contracts are a new concept. The aim of these contracts is to enlist the support of specialized private firms in turning public water utilities into competent professional operators. This report looks at how the business model for such contracts may work. This report builds on fieldwork and consultation in India. The model described in this report reflects two weeks of meetings with water sector stakeholder in India, including a workshop held at the World Bank country office in Delhi on 22 March 2011. The report gives introduction in section one. It describes briefly the need for professionalization contracts in India, and the target market section two. It then summarizes what the contractor will do, and how this differs from traditional capacity building, as well as from traditional public private partnership (PPP) concepts such as management contracts section three. The report then describes the complementary policy and institutional reforms that will be needed at the state and local government levels to make professionalization contracts successful section four. Section five looks at the political economy of professionalization contracts, identifying risks, and how these risks can be mitigated through design of the institutional reforms and the business model. Section six then turns to the true business model aspects by describing indicative costs of the professionalization contract and the complementary investments required. Section seven considers what the sources of funding for these costs would be, and section eight goes on to explain how the contractor will be paid, and hence the incentives under which it will operate. Section nine looks at the market of potential contractors, and examines their incentives to participate. Finally, section ten sets out some considerations for developing the concept.

To evaluate and reflect the sustainability of services in the region, an overall sector sustainability assessment was done, taking into account four main dimensions: access to services, quality of services, efficiency of services, and financing of services. Each of these dimensions is measured through three simple and objective indicators. For each indicator, best practice values are established by looking at the best performers in the region, and countries closest to those best performers are deemed to have a more mature sector. A more complete description of the methodology to assess the sector sustainability is included in the annex of the state of the sector regional report from the Danube Water Program. The outcomes of this assessment for the Slovenia water sector are displayed, which also shows average and best practices in the Danube region. The Slovenian sector sustainability score is 84, which is above the Danube average sustainability score of 64. The assessment shows that, on average, the country performs well in terms of access to piped water and flush toilets, affordability, continuity of service, customer satisfaction, nonrevenue water, and collection ratio. The main deficiencies of Slovenia’s water sector identified through the sector sustainability assessment are wastewater treatment coverage, operating cost ratio, and investment level. The main sector challenges are: increasing the rehabilitation of the water infrastructure and improving its reliability; and improving monitoring and reporting practices.

Nigeria has enough surface and ground water to meet domestic demand, but as of 2004 half of its urban population did not have access to piped water. And for those who did have access, water taps flowed only a few hours a day. Rapid urban population growth of 5.7 percent per year heightened the difficulties faced by State Water Agencies (SWAs) in meeting the need for piped water and expanding production capacity. Poorly maintained and aging pipes were subject to frequent leakages, and some newly built pipes carried no water owing to intermittent power supply. Nigeria’s water sector performance contrasts with that of smaller countries in West Africa, such as Niger and Burkina Faso, which, with fewer resources, have undergone major institutional reforms and made significant progress in the urban water sector. The case study is part of a series on Doing Development Differently in Nigeria. This series seeks to support the World Bank’s Nigeria country team in strengthening its effectiveness by tailoring interventions to the local context using World Bank support to leverage system wide change and systematically learn by doing. This case study is also part of the Science of Delivery case study program that is contributing to the Global Delivery Initiative’s Library of Delivery Case Studies. The Global Delivery Initiative is collaboration across the international development community to forge a new frontier in development efforts worldwide.

The overview over the next pages summarizes key themes and findings from on-going technical assistance provided to the Kenyan water sector by the Water and Sanitation Program (WSP) of the World Bank’s Water Global Practice. Kenya’s new Constitution (Constitution of Kenya 2010) came into effect in 2013, declaring water supply and sanitation services a basic right and devolving key water and sanitation functions to the county level. Key legislation, including the County Government Act of 2012 and the Urban Areas and Cities Act of 2011, have provided the framework for far reaching changes. As these changes took shape before and after the new constitution came into effect, WSP’s TA programs have been providing specific advice at the national level1 to align the sector’s legal and institutional frameworks to the new decentralized constitution. The engagement and support to counties to adopt the new frameworks has been stepped up substantially since mid-2013. This is evidenced by the progress of the transition process under the Transition Authority and Commission for the Implementation of the Constitution. This note seeks to briefly highlight priorities and practical suggestions to pursue those priorities in order to support counties as they navigate the process of devolution.

This policy paper records the outcome of a strategic analysis of investment requirements in the water sector in Zimbabwe as of December 2013. The work, entitled Zimbabwe water sector investment analysis, was undertaken in close collaboration with senior officials in Zimbabwe as an exercise in determining where World Bank investments may be most effective in the future, and to assist the government of Zimbabwe to develop its own investment strategies. The analysis was framed around two key questions: (1) what immediate investments are required to ensure that water in sufficient quantity and at adequate quality will be available to underpin recovery? This is in order to ensure that water availability would not constitute a constraint to future growth and development; and (2) where in the water sector should the next dollar be best spent? This paper summarizes the context of the water sector in Zimbabwe at the time of the study and reflects the key elements of policy advice derived from the analysis. It is important to record and recognize the key elements of policy advice provided by the World Bank through the water sector investment analysis.

This Issues Paper, requested by the former Ministry of Water Resources Development and Management as a recommendation of the National Water Policy (NWP), will contribute to the National Climate Change Response Strategy (NCCRS) by examining opportunities for adaptation to climate change in the water resources sector, using both structural and non-structural measures. It uses models to provide preliminary estimates of the possible impacts of climate change in 2050 and 2080 on these water resources. A number of opportunities to adapt to these impacts are discussed. Many of these adaptation opportunities constitute no-regrets actions, in that they are actions that are worth undertaking in their own right, irrespective of the severity of impacts from climate change.

This report outlines a 3-year program to upgrade the knowledge platform for managing water resources in Central Asia. Its ultimate purpose is to enhance the ability of all countries to engage in evidenced- based dialogue on water and energy management. It focuses on regional actions, linking all five countries plus Afghanistan, but recognizes the essential role of national initiatives. It covers the core elements of a modern decision support system and, based on extensive consultations, supports a change in accessing, developing, and sharing information and analysis. The intended outcomes of the road map are to: (i) establish a knowledge platform that is accepted by countries as a basis for cooperative actions; (ii) enhance capacity and knowledge sharing at the national and regional levels; and (iii) directly improve management of water at national and transboundary scales.

Over the past 25 years, Uganda has experienced sustained economic growth, supported by a prudent macroeconomic framework and propelled by consistent policy reforms. Annual Gross Domestic Product (GDP) growth averaged 7.4 percent in the 2000s, compared with 6.5 in the 1990s. Economic growth has enabled substantial poverty reduction, with the proportion of people living in poverty more than halving from 56 percent in the 1992 to 23.3 percent in 2009. However, welfare improvements have not been shared equally; there is increasing urban rural inequality and inequality between regions. Revitalizing economic growth and tackling persistent poverty will require addressing a number of challenges. These include alleviating infrastructure bottlenecks; increasing agricultural productivity; managing land, water and other natural resources; addressing demographic challenges; and confronting governance issues. The development and management of water resources is intimately linked to Uganda's continued development ambitions. Water can be both a positive force-providing productive input to agriculture, industry, energy and tourism, and sustaining human and environmental health-as well as a destructive one-to which the devastating consequences of floods and droughts can attest. The National Water Resources Assessment (NWRA) estimates that Uganda's total renewable water resources are about 43 million cubic meters (MCM), less than was estimated in the Ministry of Water and Environment's (MWE's) Sector Investment Plan (SIP) in 2009. About 13 percent of this is sustainable groundwater (5.67 MCM) and the balance is surface water (37.41 MCM). About one half of all districts in Uganda experience annual rainfall deficits-the difference between evapotranspiration and rainfall-ranging from slightly above zero to 400 mm. The frequency of rainfall anomalies below normal (or long-term annual average) is significantly greater than the frequency of rainfall anomalies higher than normal. The Uganda water Country Assistance Strategy (CAS) aims to assist the Government of Uganda (GoU) in identifying priority actions for building on successful outcomes, tackling remaining challenges, and exploiting opportunities in Uganda's water sector. The objective of the water CAS is to define the World Bank's strategic role in supporting GoU to better manage and develop its water resources. The recommendations of the water CAS are complementary to the World Bank Uganda Country Assistance Strategy (CAS) 2011-15 priorities for Uganda and consistent with the country's development objectives as defined in the National Development Plan (NDP) and water and related sector plans and strategies, which form the foundation of the World Bank Uganda CAS.

Weather is the term used to describe the atmospheric conditions (heat, wetness, wind, etc.) prevailing at any one place and time. Climate is the sum of the prevailing weather conditions of a given place over a period of time, typically summed over many decades. This paper seeks to provide strategic directions for mainstreaming support for climate change within the World Bank's broader program of assistance to Vietnam. It does so by reviewing the current understanding of climate change in Vietnam and likely impacts, outlining principles to guide the Bank's engagement in this field, and applying these principles across a range of sectors, taking into account both near- and longer-term considerations. The report identifies elements of the Bank's current and planned portfolio of projects and analytical work that are contributing or will contribute to improved knowledge, planning, and actions, and it points to additional areas where new or more work seems warranted. The report represents a first iteration of a strategy for supporting Vietnam in managing the challenges posed by climate change. As more experience is gathered and as our understanding of both the science and the economics of climate change impacts in Vietnam improves, this strategy will need to be revisited and refined. While the process of climate change is expected to be a long-term phenomenon-with predictions for considerable changes through the second half of the twenty-first century, the focus of this report is on decisions and priorities that should govern the Bank's assistance during this decade. Given an array of uncertainties, extending the developing assistance planning vision much beyond 2020 is not practical. This time frame also corresponds to the government of Vietnam's own planning horizon.

This report outlines the key principles of water safety planning for rural water supply in India. Water safety planning represents a change of emphasis from end-of-pipe testing to the management of risks of contamination from source to mouth. End-of-pipe testing is still necessary to verify that safe drinking water is being delivered. The focus of the report is on the policy issues concerning the adoption of water safety planning and the institutional arrangements (roles and responsibilities) needed to operationalize the approach. Recommendations are provided on demonstrating and implementing the approach to establish a full program. There are three objectives of this study: 1) to consider policies for the delivery of safe drinking water quality in rural areas; 2) to provide a framework in which the various functions associated with a change of emphasis towards managing risks to the safety of drinking water can be incorporated into existing institutional frameworks, in particular building on the initiatives already taken in India to improve monitoring and surveillance of drinking water quality; and 3) to suggest an approach to demonstrate and implement such a framework.

Infrastructure plays a key role in promoting economic growth and opportunities.In particular, the efficient provision of basic infrastructure services, like water and sanitation, is a key ingredient in fostering a country's social and economic development. Previous studies have found that infrastructure has a positive impact on output, and can improve economic opportunity, including health and education for the poor, particularly in developing countries. In Argentina, a 2005 study, found that child mortality fell by 8 percent in areas that had experienced improved coverage and quality of basic water and sanitation through utility reform, with most of the reduction occurring in low-income areas where the water network expanded the most. More generally, Fay and Morrison found that allowing the poorest quintile in developing countries the same access to basic services as the richest quintile would reduce child mortality by 8 percent and child under development by 14 percent. Calderon and Serven also found a significant positive impact of infrastructure access and quality on overall inequality. Furthermore, the book sheds some light on how to address the main challenge for the future which may be to attract specialized operators to the smaller municipalities which do not currently have them. For that purpose in Colombia, for example, over the last two years, the policy framework has been focused on promoting the sector's development, by using the departments as the intermediate institutional level between the National Government and the municipalities, to formulate programs with regional impact and promote comprehensive investment plans.

This Country Environmental Analysis (CEA) has been developed by the World Bank in cooperation with the Government of Jordan. It aims to integrate environment into development and poverty reduction priorities. The CEA will be a vital instrument for designing Jordans future policies, by integrating the economic policy tools in our decision making processes. As the latest economic crises and its implications have shown, an economic model that is based on consumption alone cannot be sustained; accordingly many countries identified the need to green their economics as the base for sustainable growth and development. Jordans green economic initiative will enhance social integration, economic growth an environmental sustainability within one focused, measured and stable economic plan. Jordan is a small country that is rich in human capital; the green journey will be a twenty years program to retrofit our infrastructure, to become energy, water and resource efficient. The recommendations identified in this document will be the main drivers for the environmental policies in the country. The issue of adequate incentives for better quantity management clearly remains important, but is not addressed in this report. After the national agenda was established, it appears that the reduction of water related subsidies and the creation of incentives for allocating water to higher value added uses are being recognized as necessities that public policies will address in the future.

Through this study, we shall go back to the water management in the urban areas of the seventeenth and eighteenth centuries, precisely at the time when a suspicious perception of the humid environment is developing. The historiographical approach of water has been evolving for almost thirty years and is fostered by contemporary issues. Water has fully become a research subject and the setting of Brittany is not neutral : its environmental, institutional and cultural characteristics play a key role in the elaboration of hydrological works. The situation evolved over the two centuries : on the local level, the major changes lie in the councils' management of the hydraulic equipments and the appointment of administrators to handle the urban affairs. The designing mission shifts also from craftmanship to engineering, and this change in the professional expertise of the designer entails repercussions on both the organization of the building site and the morphology of the equipment. This redefinition of the administrative and technical tasks influences the works' practicality; Cette étude se propose de revenir sur la gestion urbaine de l'eau aux dix-septième et dix-huitième siècles, c'est-à-dire au moment où se développe une perception suspicieuse du milieu humide.

Adaptation to climate impacts on groundwater resources in developed and developing countries has not received adequate attention. This reflects the often poorly understood impacts of climate change, the hidden nature of groundwater and the general neglect of groundwater management. Many developing countries are highly reliant on groundwater. Given expectations of reduced supply in many regions and growing demand, pressure on groundwater resources is set to escalate. This is a crucial problem and demands urgent action. This report addresses the impacts of climate change on groundwater and adaptation options. The Earth's climate is projected to become warmer and more variable. Increased global temperatures are projected to affect the hydrologic cycle, leading to changes in precipitation patterns and increases in the intensity and frequency of extreme events; reduced snow cover and widespread melting of ice; rising sea levels; and changes in soil moisture, runoff and groundwater recharge. Increased evaporation and the risk of flooding and drought could adversely affect security of water supply, particularly surface water. Due to these pressures, as well as global population growth, demand for groundwater is likely to increase.

The involvement of the rural private sector in water supply in Cambodia is unique to the country. The presence of this private sector allows other entities to respond to new demands from people living in the larger villages for household water supply, which the State is not yet able to address. These entrepreneurs operate on a merchant basis, lacking an institutional structure which is still being created. Their business is most often based on pushcart delivering water barrels at the house of villagers or more recently on small piped networks usually distributing raw surface water. Service is rough; the water quality is uncertain, but the users are satisfied with this service, because for them, it constitutes another alternative to the already considerable choice of water supplies available-ponds, wells, boreholes, and rivers. Their demands focus more on a practical objective (a supply in the household) than on a sanitary one, even if surveys show that villagers have a good understanding of health risks associated with water. Through the implementation of 14 small scale water supply systems, the goal was to enhance a qualitative improvement of the water service in some Cambodian small towns through the transformation of rough and informal merchant services to a basic water service supplying drinking water to an extended population under a formal institutional arrangement. The MIREP (Mini Reseaux d'Eau Potable - Small Scale Piped Water Supply System) program, launched in 2001 to transform these very basic initiatives into basic services, began as a pilot project supporting one entrepreneur in the implementation of a small piped water system. In order to move forward, the MIREP program made a choice, in particular linked to its proximity to the Ministry of rural development, to assist the nascent involvement of communes in decentralization, to strengthen provincial power through the process of decentralization, and to respect the cultural heritage of those who devised and financed the project.

Apesar de sua grande importância, a produção nacional dessa leguminosa é desuniforme, pois na maioria dos casos, é cultivado em áreas com baixo nível de tecnologia e por não haver um completo conhecimento das condições meteorológicas predominantes durante as épocas de cultivo. O Estado de São Paulo, de maneira geral, apresenta períodos secos e chuvosos bem definidos. No período das águas, embora haja a ocorrência de precipitação pluviométrica, esta pode ter distribuição irregular, comprometendo a produtividade do feijoeiro quando o veranico coincidir com fases críticas quanto ao requerimento de água. A irrigação regulariza o fornecimento hídrico, assegurando a produção. O presente trabalho teve por objetivo avaliar três métodos de manejo de irrigação, quais sejam: por tensiômetria, tanque “Classe A”, e pela evapotranspiração estimada pela equação de Penman Monteith. A semeadura do feijão foi realizada no dia 29/09/2008 utilizando a cultivar BRS Pontal, no espaçamento de 0,45 m entre linhas com distribuição de 14 sementes por metro. Anteriormente ao experimento, foi plantada a cultura de aveia preta (Avena stringosa Schred), na área que se encontrava em pousio há três anos, sendo o solo de textura média argilosa. Os tratamentos foram irrigados com um sistema de gotejamento superficial. Os resultados avaliados foram o balanço de água do solo, a evapotranspiração e a produtividade de grãos. Conclui-se que os métodos de manejo avaliados diferiram entre si no plantio convencional e todos apresentaram produtividades significativamente superiores à da testemunha não irrigada. No sistema preparo convencional do solo o manejo da irrigação... Beans are the food of many Brazilians being produced throughout the country, in different climatic and cultivation conditions. Although its importance, the national production of this legume is floating, as in most cases, is grown in areas with low level of technology and the knowledge lack weather conditions prevailing during the growing season. Has Sao Paulo State has, in general, periods of rainy and dry well defined. In the rainy season, although the occurrence of rainfall, it can have uneven distribution, affecting bean yield when the drought to coincide with critical stages on the water requirement. The irrigation regulates water supply, ensuring the production. The purpose of this study is evaluating three methods of irrigation management: tensiometer, the Class A Pan, and the evapotranspiration estimated by the Penman Monteith equation. The sowing of beans was held on 29/09/2008 using the BRS Pontal, spaced 0.45 m between rows with distribution of 14 seeds per meter. Before the experiment, the crop was planted oat (Avena stringosa Schred) in the area that was fallow for three years, the soil of medium texture soil. The treatments were irrigated with a drip irrigation system. The results were evaluated the balance of soil moisture, evapotranspiration and yield. Concluded that the management methods evaluated differed in conventional tillage and all had yields significantly higher than the control without irrigation. In the conventional system of soil water management was most effective use of water applied in relation to no-tillage system.

In the past decade, Tanzania has experienced high economic growth and it is in the global limelight as a recent success story in Africa. A variety of factors have contributed to this success, including liberalized policies and reforms, infusion of external capital from development partners and the private sector, debt cancellation, and a strong performance by emerging sectors such as mining, tourism, and fisheries. Its social policies, largely influenced by the First President Julius Kambarage Nyerere, including a single national language and relative political stability have contributed to a strong sense of nationhood, which sets it apart from many of its neighbors and has provided an unusual degree of stability that has facilitated major economic transformation without a significant social backlash.
