Transboundary Water Cooperation Helps Build Climate Resilience

Water does not respect geopolitical boundaries. Hydrological systems are completely oblivious of international relations. This makes life complicated for the water managers, financiers, diplomats, and most of all – the water users around the world’s approximately 276 transboundary river basins, 63 of which are in Africa. Sixty percent of the world’s freshwater flows are in transboundary rivers, and 40% of the world’s population lives in their river basins. When water cuts across borders, it poses economic, financial, logistical and political challenges for people trying to manage and develop the resource.​

increasing uncertainty about where and​ when water will​ be available. It is affecting billions of people living in transboundary basins, and as​ often happens, the poor are the hardest hit.​ There is a long list of potential problems people will face – supply in water-stressed regions will diminish; some regions are likely to have more water than they can handle; most challenging is the fact that​ the timing and amounts of future water availability are impossible to predict with certainty. Other risks - the increasing intensity of droughts, floods, typhoons, and monsoons; uncertainties around waterborne disease; glacier melt and decreased storage in snow-pack; glacial-lake outburst floods; sea-level rise and salt-water intrusion - all pose the highest risk to poor communities that are least able to cope.

How can we ensure that we build water and climate resilient cities?

As population and economic growth bump up against finite—and increasingly degraded—water resources, competition between agricultural, industrial, and municipal water uses increases, putting stress on existing water sources. This stress is felt most acutely in urban areas, particularly among the urban poor.
 
Moreover, urban water management systems are inefficient, leading to an uneven quantity and availability of water and related services. In addition, urban water management must consider the effects of climate change, including rising temperatures, changes in precipitation patterns, and climate variability, on water resource availability.

Addressing these challenges requires building resilience not only in cities’ physical infrastructures but also in their social architecture, governance structures, financial systems, and ecosystems. A resilient city can adapt to changing conditions and withstand shocks while still providing essential services.

The case for solar water pumps

The cost of solar technology has come down, way down, making it is a viable way to expand access to energy for hundreds of millions of people living in energy poverty. For farmers in developing countries, the growing availability of solar water pumps offers a viable alternative to system dependent on fossil fuel or grid electricity. While relatively limited, experience in several countries shows how solar irrigation pumps can make farmers more resilient against the erratic shifts in rainfall patterns caused by climate change or the unreliable supply and high costs of fossil fuels needed to operate water pumps. Experience also suggests a number of creative ways that potential water resource trade-offs can be addressed.

Eau : le point de rupture

La Banque mondiale à la Semaine mondiale de l’eau 2015

Le thème ne pouvait être mieux choisi pour l’édition 2015 de la Semaine mondiale de l’eau de Stockholm : « De l’eau pour le développement ». L’eau est en effet un secteur crucial et qui atteint un point critique dans les affaires internationales. Au cours des 20 prochaines années et au-delà, la course à la sécurité alimentaire et énergétique et à une urbanisation durable exercera des pressions nouvelles et croissantes sur les ressources hydriques. 

Water: At a Tipping Point

The World Bank at World Water Week 2015

The Stockholm World Water Week’s focus on “Water for Development” comes at an opportune time. Water as a sector in world affairs is reaching a tipping point. Over the next two decades and more, the global push for food and energy security and for sustaining urbanization will place new and increasing demands on the water sector. 

Ours is a world of ‘thirsty agriculture’ and ‘thirsty energy’ competing with the needs of ‘thirsty cities.’ At the same time, climate change may potentially worsen the situation by increasing water stress as well as extreme events, reminding us that the water and climate nexus can no longer be a side event at global climate talks. All of this is happening in a context where the important agenda of access to services – despite the impressive gains over the past several decades – remains an unfinished agenda, requiring an urgent push if we are to fulfill the promise of universal access.

Los recursos hídricos se encuentran en un momento crítico

El Banco Mundial en la Semana Mundial del Agua 2015

La Semana Mundial del Agua en Estocolmo se centra en el tema “Agua para el Desarrollo”, lo cual llega en un momento oportuno. Entre los asuntos mundiales, el sector del agua está llegando a un momento crítico. Durante las próximas dos décadas y posteriormente, los esfuerzos en el mundo encaminados a lograr la seguridad alimentaria y energética y la urbanización sostenible crearán nuevas y mayores demandas en relación con los recursos hídricos. 

Why it’s time to elevate groundwater

Jacob Burke's picture

Groundwater stored in the earth’s crust underpins all our lives – the ultimate source of freshwater for billions has become victim of over-extraction and the ultimate sink for pollutants.
 
For too long, not enough has been done to regulate the use of this precious, on-demand resource and manage disposal of waste. If rates of groundwater depletion have tripled in the past 3 decades, then the rate at which pollutants have accumulated in shallow aquifers can only have equaled or exceeded that rate.
 
The lack of care given to groundwater is placing a huge tax on the poor who have no access to clean piped water supply and depend on groundwater for their health and livelihoods. Self-supply, through the use of wells, from polluted aquifers in urban and rural areas is widespread, but un-reported. The impacts are all too apparent in the densely populated urban slums and rural communities that often live just centimeters above polluted soil and rock. Out-migration of poor farmers who are no longer able to access deepening groundwater tables has been a feature in arid and semi-arid regions, but intensive agriculture is also leaving behind a legacy of nitrates and pesticides which imprint aquifers for decades.

Why Water Presents Special Challenges: A Brief Rationale for Water Resource Economics

For the first time, the International Water Resource Economics Consortium (IWREC) held its annual meeting at The World Bank from September 7-9, 2014. The meeting, an annual gathering of water economists, serves as a place to exchange the latest information and research findings in the field.

Join us for World Water Week

Whether you'll be attending the upcoming World Water Week in person or following online, there's a lot to look forward to this year. This year's theme focuses on Energy and Water and along with Sustainable Energy for All (SE4ALL) and the International Union for Conservation of Nature (IUCN), The World Bank Group is excited to join as a collaborating partner.

In China, Innovation in Water Rights Leads to Real Water Savings

China’s most arid regions are facing an increasingly serious water crisis, and local water policies often aggravate the problem. In such climates, growth in the agricultural sector has come with high environmental costs.

With the help of new technologies that measure real water consumption in agriculture, governments are designing innovative water rights systems that actually save water. Based on results from two successful pilots, the World Bank Group is partnering with China to tap into science to transform water management in agriculture at the national level.
