WATER RESOURCES MANAGEMENT

The World Bank

Water scarcity affects more than 40% of the global population. Water-related disasters account for 70% of all deaths related to natural disasters. The World Bank helps countries ensure sustainability of water use, build climate resilience and strengthen integrated management.

Today, most countries are placing unprecedented pressure on water resources. The global population is growing fast, and estimates show that with current practices, the world will face a 40% shortfall between forecast demand and available supply of water by 2030. Furthermore, chronic water scarcity, hydrological uncertainty, and extreme weather events (floods and droughts) are perceived as some of the biggest threats to global prosperity and stability. Acknowledgment of the role that water scarcity and drought are playing in aggravating fragility and conflict is increasing.

Water Resource Management

Feeding 10 billion people by 2050 will require a 50% increase in agricultural production, (which consumes 70% of the resource today), and a 15% increase in water withdrawals. Besides this increasing demand, the resource is already scarce in many parts of the world. Estimates indicate that over 40% of the world population live in water scarce areas, and approximately ¼ of world’s GDP is exposed to this challenge. By 2040, an estimated one in four children will live in areas with extreme water shortages. Water security is a major – and often growing –challenge for many countries today.

Climate change will worsen the situation by altering hydrological cycles, making water more unpredictable and increasing the frequency and intensity of floods and droughts. The roughly 1 billion people living in monsoonal basins and the 500 million people living in deltas are especially vulnerable. Flood damages are estimated around $120 billion per year (only from property damage), and droughts pose, among others, constraints to the rural poor, highly dependent on rainfall variability for subsistence.

The fragmentation of this resource also constrains water security. There are 276 transboundary basins, shared by 148 countries, which account for 60% of the global freshwater flow. Similarly, 300 aquifers systems are transboundary in nature, with 2.5 billion people worldwide are dependent on groundwater. The challenges of fragmentation are often replicated at the national scale, meaning cooperation is needed to achieve optimal water resources management and development solutions for all riparians. To deal with these complex and interlinked water challenges, countries will need to improve the way they manage their water resources and associated services.

To strengthen water security against this backdrop of increasing demand, water scarcity, growing uncertainty, greater extremes, and fragmentation challenges, clients will need to invest in institutional strengthening, information management, and (natural and man-made) infrastructure development. Institutional tools such as legal and regulatory frameworks, water pricing, and incentives are needed to better allocate, regulate, and conserve water resources. Information systems are needed for resource monitoring, decision making under uncertainty, systems analyses, and hydro-meteorological forecast and warning. Investments in innovative technologies for enhancing productivity, conserving and protecting resources, recycling storm water and wastewater, and developing non-conventional water sources should be explored in addition to seeking opportunities for enhanced water storage, including aquifer recharge and recovery. Ensuring the rapid dissemination and appropriate adaptation or application of these advances will be a key to strengthening global water security.

The World Bank is committed to assisting countries meet their economic growth and poverty reduction targets based on the Sustainable Development Goals (SDGs). Particularly, water resource management is tackled in SDG 6.5, but other SDGs and targets require water resource management for their achievement. Accordingly, the Bank has a major interest in helping countries achieve water security through sound and robust water resource management.

Water security is the goal of water resources management. For a rapidly growing and urbanizing global population, against a backdrop of increasing climatic and non-climatic uncertainties, it is not possible to "predict and plan" a single path to water security. To strengthen water security we need to build capacity, adaptability, and resilience for the future planning and management of water resources.

Water Resources Management (WRM) is the process of planning, developing, and managing water resources, in terms of both water quantity and quality, across all water uses. It includes the institutions, infrastructure, incentives, and information systems that support and guide water management. Water resources management seeks to harness the benefits of water by ensuring there is sufficient water of adequate quality for drinking water and sanitation services, food production, energy generation, inland water transport, and water-based recreational, as well as sustaining healthy water-dependent ecosystems and protecting the aesthetic and spiritual values of lakes, rivers, and estuaries. Water resource management also entails managing water-related risks, including floods, drought, and contamination. The complexity of relationships between water and households, economies, and ecosystems, requires integrated management that accounts for the synergies and tradeoffs of water's great number uses and values.

Water security is achieved when water's productive potential is leveraged and its destructive potential is managed. Water security differs from concepts of food security or energy security because the challenge is not only one of securing adequate resource provision – but also of mitigating the hazards that water presents where it is not well managed. Water security reflects the actions that can or have been taken to ensure sustainable water resource use, to deliver reliable water services, and to manage and mitigate water-related risks. Water security suggests a dynamic construct that goes beyond single-issue goals such as water scarcity, pollution, or access to water and sanitation, to think more broadly about societies' expectations, choices, and achievements with respect to water management. It is a dynamic policy goal, which changes as societies' values and economic well-being evolve, and as exposure to and societies' tolerance of water-related risks change. It must contend with issues of equity.

The Water Security and Integrated Water Resources Management Global Solutions Group (GSG) supports the Bank's analytical, advisory, and operational engagements to help clients achieve their goals of water security. Achieving water security in the context of growing water scarcity, greater unpredictability, degrading water quality and aquatic ecosystems, and more frequent droughts and floods, will require a more integrated and longer-term approach to water management. Key areas of focus will be ensuring sustainability of water resources, building climate resilience, and strengthening integrated management to achieve the Global Practice's (GP) goals and the SDGs. The GSG will work with a multiple GPs and Cross Cutting Solutions Areas (CCSAs) directly through water resources management or multi-sectoral projects and indirectly through agriculture, energy, environment, climate, or urban projects.

Robust water resource management solutions to complex water issues incorporate cutting-edge knowledge and innovation, which are integrated into water projects to strengthen their impact. New knowledge that draws on the World Bank Group’s global experiences, as well as partner expertise, are filling global knowledge gaps and transforming the design of water investment projects to deliver results. Multi-year, programmatic engagements in strategic areas are designed to make dramatic economic improvements in the long term and improve the livelihoods of millions of the world’s poorest people.

The Water Security Diagnostic Initiative is an analytical framework that can be used to examine the status and trends related to water resources, water services, and water-related risks, including climate change, transboundary waters, and virtual water trade. The framework helps countries determine if and to what extent water-related factors impact people, the economy, and the environment, and determine if and to what extent water-related factors provide opportunities for development and well-being.

The World Bank is proactively working to address new global challenges, by adapting its operations to reach those that most need it today. Working across sectors is ensuring that water considerations are addressed in energy, the environment, agriculture, urban and rural development, and within new global challenges. The Bank also supports transformational engagements and initiatives, which seek to optimize spatial, green, and co-benefits among water and other infrastructure sectors. A large proportion of World Bank-funded water resources management projects include institutional and policy components.

Recent initiatives include:

With 263 international rivers in the world, support for cooperative transboundary water management can make an important contribution towards improving the efficient and equitable management of water resources. The Bank supports transboundary waters through Multi-Donor Trust Funds (MDTF), knowledge pieces, and its lending portfolio:

The Bank follows an integrated flood management agenda, which includes well-functioning early warning systems, infrastructure, and institutional arrangements for coordinated action to address increased variability and changes to runoff and flooding patterns. In addition, a new perspective, referred to as an "EPIC Response," is offered to better manage hydro-climatic risks: This perspective looks at floods and droughts not as independent events but rather as different ends of the same hydro-climatic spectrum that are inextricably linked. The EPIC response provides a comprehensive framework to help national governments lead a whole-of-society effort to manage these risks.

Water scarcity is also addressed in:

Sustainable groundwater management is also a priority of the World Bank, and central to water security in many countries.
