The Water, Energy and Food Security Nexus - Lessons from India for Development

In this book, the authors show how these issues are being addressed in India as part of its economic development, and how these can provide lessons for other developing nations. They address the conflicting claims of water resources for irrigation and hydropower, where both are scarce at the national level for fostering water and energy security. They also consider the relationship between water for irrigated agriculture and household use and its impact on rural poverty. They identify weaknesses in the current hydropower development programme in India that are preventing it from being an ecologically sustainable, socially just and economically viable solution to meeting growing energy demand. The empirical analyses presented show the enormous scope for co-management of water, energy, agricultural growth and food security through appropriate technological interventions and market instruments. - Edited by M.

The Status of the Water-Food-Energy Nexus in Asia and the Pacific

The debate on natural resource scarcity was recently reignited. New scientific findings suggest that humanity has exceeded the planetary boundaries, threatening its own safe operation. Five attributes characterize the new realism of physical and economic scarcity of key resources: lack of undeveloped resource preserves, challenges of exploiting new resources, emergence of new consumers, volatility of resource prices and broadening of actors in governing resources. Of all the natural resources, water, food and energy are most needed to sustain life on earth. These three resources are tightly interconnected, forming a resource and policy nexus. Their insecurity is an impediment to social stability and economic growth. This report traces the debate, analysis and action on the water, food and energy (WFE) security nexus. Considering the complex interactions of these three resources will require new institutional capacity in both industrialized and developing countries. For the nexus approach to achieve the twin goals of human well-being and green growth, sustainability must move center-stage, with attention given to ecosystem services. The increase in resource use in Asia and the Pacific region between 1970 and 2005 was above the world average. This economic growth resulted in the region’s reliance on fossil fuel sources. Countries in Asia and the Pacific region accounted for almost half the world’s CO2 emissions in 2008. The security of water, food and energy resources in the region has been compromised in parallel with decades of economic development. The fastest increase in water demand in Asia is now coming from the industry and urban households, not agriculture. For decades, economic growth in Asia has required ever-expanding amounts of energy. On food security, over 20 per cent of the undernourished populations live in South and South-West Asia, with the most acute problems in Afghanistan. Currently, there is only rudimentary understanding of the complex and pervasive connections between water, food and energy security in the region. This position paper reviews the region’s experiences with the interlocking effects of the WFE nexus, which results in challenges that cross two or even all three of the domains. Examples include biofuel; hydropower; thermoelectric production and water security; irrigation and food security; irrigation and energy security; food trade and virtual water, land and food security; and the intertwining effect of water production and energy security. The meaning of the nexus is further explored by using two case studies, namely Central Asia and the Mekong Basin. Not surprisingly, in existing policy frameworks, energy and water policies are developed largely in isolation from one another. The concluding section outlines five key areas of policy interventions needed to mainstream the nexus concept in Asia and the Pacific region.

Toward a Sustainable Energy Future for All: Directions for the World Bank Group’s Energy Sector

As global energy markets evolve rapidly, producing and maintaining a reliable power supply for many countries in the developing world remains a significant issue. The World Bank Group will approach this energy crisis in partnership with the United Nations Sustainable Energy for All initiative. Client countries focus on universal access, accelerating improvements in energy efficiency, and doubling the global share of renewable energy by 2030. Achieving these goals will help to end extreme poverty, because economic growth and shared prosperity is not possible without access to energy. Even with the proper infrastructure for energy production, prices often remain higher than the global average, resulting in households using self-supplied alternatives such as unclean, diesel generators. To remedy this situation, energy must be distributed and consumed efficiently through programs supported by a sound pricing and tariff policy, by subsidies targeting the poor, and by mechanisms for carbon pricing. The World Bank Group is committed to providing long-term solutions tailored to specific circumstances of each client country in the areas of renewable energy, natural gas, transmission and distribution, regional trade and market integration, financial performance, sector planning, access, and post-conflict reconstruction.

Global Trends 2030: Alternative Worlds

The U.S. National Intelligence Council identifies the Water-Energy-Food Nexus as one of the mega trends for the coming decades. “The increasing nexus among food, water, and energy - in combination with climate change - will have far-reaching effects on global development over the next 15-20 years. In a tectonic shift, demand for these resources will grow substantially owing to an increase in the global population from 7.1 billion today to 8.3 billion by 2030.”

Overview of the Water-Energy Nexus in the United States

State legislatures and natural resource managers have traditionally addressed water and energy as two separate issues. However, water and energy are deeply connected and sustainable management of either resource requires consideration of the other. Thus, resource managers and lawmakers across the country are beginning to take a comprehensive and interdisciplinary approach to the management of water and energy. This report provides overview information about the nexus between water and energy and provides a summary of state legislation addressing this issue.

Energy-water Nexus: Energy Use in the Municipal, Industrial, and Agricultural Water Sectors

Industrial processes rely on water for cooling, chemical solvents, cleaning, just to name a few. Forty percent of the worlds’ food is produced from irrigated lands. However, much of this would not be possible without energy; which is a critical input to pump, move, and treat the water required by municipalities, industries and agriculture. Ironically, however, much of this energy would not be available without water to turn turbines, wash inputs, or cool equipment. Thus in many cases use of one resource is inextricably linked to use of the other - hence, the energy-water nexus.

Hydroclimatic shifts driven by human water use for food and energy production

Hydrological change is a central part of global change. Its drivers in the past need to be understood and quantified for accurate projection of disruptive future changes. Here we analyse past hydro-climatic, agricultural and hydropower changes from twentieth century data for nine major Swedish drainage basins, and synthesize and compare these results with other regional and global assessments of hydrological change by irrigation and deforestation. Cross-regional comparison shows similar increases of evapotranspiration by non-irrigated agriculture and hydropower as for irrigated agriculture. In the Swedish basins, non-irrigated agriculture has also increased, whereas hydropower has decreased temporal runoff variability. A global indication of the regional results is a net total increase of evapotranspiration that is larger than a proposed associated planetary boundary. This emphasizes the need for climate and Earth system models to account for different human uses of water as anthropogenic drivers of hydro-climatic change. The present study shows how these drivers and their effects can be distinguished and quantified for hydrological basins on different scales and in different world regions. This should encourage further exploration of greater basin variety for better understanding of anthropogenic hydro-climatic change.

Water and Energy - Threats and Opportunities

This book creates an awareness of the important couplings between water and energy. It shows how energy is used in all the various water cycle operations and demonstrates how water is used – and misused – in all kinds of energy production and generation. Population increase, climate change and an increasing competition between food and fuel production create enormous pressures on both water and energy availability. Since there is no replacement for water, water security looks more crucial than energy security. This is true not only in developing countries but also in the most advanced countries. The western parts of the USA suffer from water scarcity that provides a real security threat. The book does not aim to show “how to design” or to solve some of the very intricate conflicts between water and energy. Instead it systematically lists ideas, possibilities and a number of results. There are a few more technical chapters that act as entry points to more detailed technical literature - by Gustaf Olsson

Balancing Economic Growth and Environmental Sustainability: Focusing on Food-Water-Energy Nexus

A major international conference was held by CEP-BCI in February 2012. The conference benchmarked GMS economic growth between 2001 and 2010 and its impact on environmental and social development as well as provided an outlook for the next decade. Topics discussed included known and emerging economic, environmental, and climate change challenges in the context of food, water and energy security, and participants charted out key strategic thrusts for the coming decade. More than 233 delegates, including senior government officials from the GMS countries, private sector representatives and development partners attended. The conference outcomes have provided important inputs to the GMS program in general, and CEP-BCI Phase II in particular. During the next decade, emphasis will need to be placed on the management of food, water and energy resources in the GMS, which requires a careful balance of economic and environmental interests and better management of natural resources.

Messages for Rio

A Climate-Safe “Green Economy” Protects Rivers, Rejects Destructive Dams

The twentieth anniversary of the UN Conference on Sustainable Development, or Rio+20, comes at a time when human-caused emissions have pushed our planet to the brink of a climate crisis. The effects of the global industrial economy brought planetary levels of carbon dioxide to a record high of 31.6 gigatonnes (Gt) in 2011, according to a 2012 International Energy Agency (IEA) report – only 1 Gt below the level that the IEA considers necessary to keep global temperatures from rising beyond 2°C. In response, many governments, banks, and corporations are increasingly looking to large hydropower dams to reduce fossil fuel use. Proponents claim that large hydropower dams will help usher in a “green economy.” Rather than achieving greater protection of the planet’s ecosystems from the demands of growing energy use, this policy direction will put an increasing burden on Earth’s freshwater species and habitats.

Contribution of Himalayan Ecosystems to Water, Energy, and Food Security in South Asia: A nexus approach

In the face of climatic and other socioeconomic changes, most South Asian countries having large and growing population, limited land resources, and increasing water stress face a common challenge of how to grow more food with the same or less land, less water, and increased energy prices. This concept paper seeks deeper understanding of the interlinkages among water, energy, and food, which is crucial to formulate cross-sectoral policies for more resilient and adaptable societies. In South Asia, such a nexus approach inevitably needs to take Himalayan ecosystem services into account. Rice and wheat, the staple foods in South Asia, require huge amounts of both water and energy. The Indus-Ganges-Brahmaputra plain - the sub-region’s grain basket and one of the world’s largest areas of irrigated agriculture - depends in large part on the Himalayan mountain system as a source of both surface and groundwater for irrigation; as a source of hydropower; and as a regulator of climate and a repository of agro-biodiversity. To sustain these services and to ensure both upstream and downstream food, water, and energy security in South Asia, policies and strategies must therefore promote improved management of Himalayan watersheds, forests, wetlands, and rangelands. Recommended measures include support to restoration of natural water storage capacity; development of climate smart, environmentally and socially sound water infrastructure; adequate investment for natural resource management; and incentives to mountain communities for managing Himalayan ecosystems.

The Water Security Nexus – Challenges and Opportunities for Development Cooperation

Is water the “gold of the 21st century,” potentially triggering “water wars” between countries sharing the precious resource? Such scenarios proliferated in the 1990s, but today a different paradigm is taking root. Politicians are beginning to emphasise the peace dividend of water cooperation; and development agencies are now supporting transboundary water cooperation projects around the world. And even at the highest level of political discourse, water cooperation has been identified as an entry point for broader peacebuilding.

Regional Options for Addressing the Water, Energy and Food Nexus in Central Asia and the Aral Sea Basin

This article explores the water, energy and food nexus in Central Asia as an avenue to seek regional solutions to common challenges. A benefit-sharing scheme was in place between the countries in the Central Asia in the Soviet Union era, but since independence unilateral action has been the norm. It is concluded that a regional integrative approach would be beneficial in the water, energy and food nexus. Collaborative options include exploring existing regional frameworks with a focus on additional investment in hydropower power generation, regional power market development, irrigation reforms, and addressing regional environmental public goods such as water flows and quality.

Putting Nature in the Nexus: Investing in Natural Infrastructure to Advance Water-Energy-Food Security

Nature is the unseen dimension of the nexus. With its functions integral to the three securities and their inter-dependence, nature is part of the infrastructure needed to manage the nexus and its resilience. Nature helps mediate the nexus links, by storing, moving, cleaning and buffering flows of water, making drought and flood less severe, and food and energy production more reliable. Without healthy ecosystems in well-functioning watersheds, the infrastructure built for irrigation, hydropower or municipal water supply does not function sustainably, and is unlikely to achieve the economic returns necessary to justify investments.

Food and Power in Sri Lanka: The Water Nexus

Sri Lanka is highly dependant on hydro-generation for much of its power needs. Nearly 50 percent of the country’s power is water-based. With the continued drought, power prices are likely to increase as only 13 percent of the country’s power needs are being met. The poorer sections of the country are likely to be hit hardest, as the government is forced to import oil to meet power needs. The water shortages in the past have slowed down economic growth for the water dependant isle.

Blog: What do climate change, water and energy have in common? - And the role of renewables in solving the conundrum

What do climate change, water and energy have in common? These seem to be three different concepts. Yet these increasingly hot button issues are, in fact, interdependent. Water and energy are inextricably linked. Water is used in nearly all energy processes, from extraction to electricity production. Energy is used to create fresh water—a process known as desalination. A carbon-intensive energy sector leads to climate change, which, in turn, increases the risks of both water stress and floods, thus affecting water supply and water quality.

‘Energy for Water’ May Have Greater Impact on the Nexus

In The Guardian’s series on the water-food-energy nexus, Tim Smedley looks at the amount of energy we use to pump, clean and transport water. The US alone uses 520bn kilowatt‐hours (kWh) to move, treat and heat its water, which accounts for up to 60% of the energy bill in some cities, and 90% of the energy bill on some farms.

The Water Food Energy Nexus

Water, food and energy are interconnected. Agriculture accounts for about 70% of global freshwater use and can pollute freshwater supplies if mismanaged. Water is also used to generate electricity: in the USA, power generation accounts for about 50% of all freshwater withdrawals3and drought in countries that use hydropower – Ethiopia and Ghana, for example – can lead to black-outs. Energy, in turn, is needed to fertilise and transport crops, which can themselves be used as biofuel to create energy. Large amounts of energy are also required to pump water to drier regions and, as water scarcity increases, so will the energy needed for technologies such as desalination. - This is good news; the leap forward in quality of life for so many millions is something to celebrate. But this growth could be jeopardised by the resource challenge being felt across the world. The expanding population will need 70% more food, and growing and processing this food will increase water stress. The Water Resources Group, of which SABMiller is a member, estimates that there could be about 40% shortfall between water demand and available freshwater supply by 2030 - by Andy Wales, SAB Miller

No Wars for Water - Why Climate Change Has Not Led to Conflict

In short, predictions of a Water World War are overwrought. However, tensions over water usage can still exacerbate other existing regional conflicts. Climate change is expected to intensify droughts, floods, and other extreme weather conditions that jeopardize freshwater quantity and quality and therefore act as a threat-multiplier, making shaky regions shakier -by

The Energy-Water Nexus - Using physics and estimation to assess energy, growth, options

The principal challenge of this century, in my view, will be adapting to a life without abundant, cheap fossil fuels. It has been the lifeblood of our society, and turns out to have some really fantastic qualities. The jury is still out as to whether we will develop suitable/affordable replacements. But additional challenges loom in parallel. Water is very likely to be one of them, which is especially pertinent in my region. For true believers in the universality of substitution, let me suggest two things. First, come to terms with the finite compactness of the periodic table. Second, try substituting delicious H2O with H2O2. It has an extra oxygen atom, and we all know that oxygen is a vital requisite for life, so our new product will be super-easy to market. Never-mind the hydrogen peroxide taste, and the death that will surely visit anyone foolish enough to adopt this substitution. Sometimes we’re just stuck without substitutes - by Tom Murphy

Asia’s Water Crisis Needs Urgent Fixing

Asia’s water crisis is at the heart of the world’s water challenges, where the degradation of surface and subterranean water resources threatens the ecosystem. With Asia facing the world’s lowest per capita access to fresh water, the continent’s ever-deeper search for water is sucking groundwater reserves dry with millions of pump-operated wells even as it confronts river depletion. Groundwater is recklessly exploited because it is not visible to the human eye. What is out of sight tends to be out of mind, as people drill ever deeper into the receding water table. At least seven factors have contributed to the rising economic and security risks linked with the Asian water crisis.

Climate change challenges power plant operations

Drought and rising temperatures are forcing water managers across the country to scramble for ways to produce the same amount of power from the hydroelectric grid with less water, including from behemoths such as the Hoover Dam. Hydropower is not the only part of the nation’s energy system that appears increasingly vulnerable to the impact of climate change, as low water levels affect coal-fired and nuclear power plants’ operations and impede the passage of coal barges along the Mississippi River.

There is an urgent need for policy cohesion on water and energy that does not exist today

If Europe is serious about reducing its dependence on imported fossil fuels and reaching its target for renewable energy (20% of supplies by 2020), policymakers must understand that water is a central component of tomorrow’s energy mix. Water is critical for fuel production and power generation, and hydropower systems can store energy efficiently.

Bring the Water-Energy Nexus to Rio+20

Global demand for energy will increase 30 percent by 2030, according to estimates, but in regions that are experiencing rapid economic growth, the increased demand for energy will lead to increased demand for water. The conflicting nature of achieving both water and energy security is exacerbated by a lack of institutional policy frameworks that integrate both concepts. However, the upcoming UN Rio+20 Sustainable Development Conference could provide an opportunity to change that.

Getting to grips with the water-energy-food “nexus”

The ‘nexus’ has become a popular buzz word to describe the complex linkages among water, energy and food security – sectors that have traditionally remained fairly separate. Talk of the water-energy-food nexus was a hot topic at last month’s Planet Under Pressure conference; it is also the focus of a significant German government-organised input to the UN Rio+20 Summit. What has brought nexus thinking to the fore, and what does this nexus look like? How does it relate to climate compatible development?

Joined-up thinking on water, energy and food

Africa’s third longest river, the Niger, is a source of water, food and energy for nine West African countries. But frequent droughts induced by a changing climate, and exacerbated by rapidly growing demand, pose a threat to water availability and livelihoods. However, countries and communities can overcome the problem of how to share water resources if they adopt what scientists call “the nexus approach”, a key agenda item at the week-long Water Forum in Marseilles, France.
