Fresh water is essential for life. No plant, animal or person can live without it.
However, water abundance cannot be taken for granted everywhere. A dry spell and record temperatures caught up with Europe this summer, testing farmers from Scandinavia and England as well as France, Netherlands, Germany and southern European countries. The level of the Rhine, Germany’s most important river, was historically low, making freight transport almost impossible on some stretches. Along the Elbe in Czechia, “hunger stones” — inscribed boulders with often-bitter warnings marking very low water levels — were again visible.
Cape Town almost ran out of water in South Africa, California has struggled with scarcity in recent years and Australia experienced its “Millennium drought” not so long ago.
The shifting temperature and precipitation patterns of climate change have increased water stress in Europe and elsewhere, but these factors that change water supply are by no means the only culprits. Not to be ignored are population growth and increasing economic activity that often go hand-in-hand with higher water demand and water pollution that reduces available freshwater resources.
Agronomist Stefan Siebert and the hydrologist Paolo D’Odorico emphasize that the production of the things we use or consume takes lots of water, and this “virtual water” trumps by any measure our direct water use. The water footprint of 1 kilogram of steak, say, is over 15,000 liters, or more than 100 times what an American uses for cooking, cleaning or hygiene per day. Agriculture feeds the world’s ever-growing population and is by far the largest water user. Hence, how agricultural production and related supply chains are organized matters a great deal.
As water becomes scarce, it is key to allocate scarce water efficiently, both locally and globally. In market economies, rising prices typically signal scarcity, which may trigger increased supply, spur innovation or decrease demand. Interestingly, however, water prices are often set independent of scarcity.
Increased water stress forces societies to calibrate their water quality and allocate their scarce water efficiently. The challenges call for pricing water properly, fine-tuning water laws and regulations, and more broadly, leveraging society’s ability to adapt and innovate.
The ubiquity of water and the multifaceted role it plays invites a multidisciplinary analysis of how it affects our lives.
Experts from European and American universities and think tanks develop insights on water challenges by researching history, hydrology, law, agronomy, economics, engineering, architecture, public policy and more. The answers to the water challenge go beyond academia and traditional policy channels, however. They require the broader engagement of civil society — business, philanthropic and nonprofit initiatives.
Showcasing the Value of a Multidisciplinary Approach to Tackling Water Challenges
To begin to make sense of the complexity, I recently agreed to serve (with Nicole Shea) as editor of a double issue on water for EuropeNow, the online journal of the European Studies Association at Columbia University. The double issue showcases the incredible diversity of academic study and institutional effort applied to these challenges. By showcasing the value of a multidisciplinary examination of global water challenges, I hope organizational leaders around the world may begin to better grasp the issues and possible solutions. Below are short summaries of the many topics covered in the issue, written by experts from around the world:
- UVA School of Engineering and Applied Sciences Professor Geoff Geise discusses the future of desalination and points out that it is hard to adopt innovations that are relatively costly if there is limited willingness to pay for water.
- Pricing water is not trivial, and nobody gains by blindly following market forces in any The economists Javier Donna and Jose Espín-Sánchez discuss a historical example of two cities in Spain to show that water markets can fail in some circumstances.
- Alexandra Campbell-Ferrari and Luke Wilson study access to water in advanced economies and encourage us to think carefully about water pricing in the context of less affluent water users. They advocate employing the full flexibility of water pricing backed up by laws and regulations. They also move forward the all-too-often emotional discussion of water as a human right.
- Legal scholar Robin Craig takes a transatlantic perspective and offers a unique comparison of the EU Water Framework Directive of 2000 and the United States Clean Water Act of 1972, which both seek to improve water management and the health of waterbodies.
- Environmental scientists Ralf Schaefer, Mira Kattwinkel and Elizabeth Berger put the EU Water Framework to the test. The EU directive is a long way from reaching its goals, and the authors call out the lack of harmonization of water quality data.
- Monica Garcia Quesada and David Aubin analyze the institutional struggle of a divided country such as Belgium with the quality of its waterways, laying bare challenges of European water legislation.
- Political scientist Neda Zachary revisits the challenge of coordination in the international context of transboundary rivers. Even though water does not stop at borders and may link very different countries, Zachary debunks the popular notion of “water wars.”
- Climate puts us all on notice and challenges societal adaptability. UVA urban planner Tim Beatley turns to “blue cities” — coastal cities — and their relationship with water. Beatley inevitably analyzes the prospect of climate change with more storms and sea-level rise.
- Historian Dagomar Degroot places us back in 17th century Holland and the Little Ice Age. Climatic cooling in the northern hemisphere forced this water-rich area to adapt, often in surprising ways.
- Ellen Arnold’s historical piece investigates extreme weather (droughts and floods) in the Middle Ages. Interwoven in the collective memory is often a sense of community, common action and leadership in the face of natural disasters.
Why Government Solutions Alone Come Up Dry
Powerful and, in many instances, effective responses to water crises come through public policies that leverage a government’s resources and its power to incentivize or regulate behavior. In water matters, progress has been made, but government action often still leaves ample room for improvement. This harks back to the basic questions of leadership and the common willingness to act that Arnold’s reading of medieval texts brought to the fore. Many key concerns about government action remain:
- The ambitions of the EU Water Framework are laudable but far from realized.
- Water quality in Europe and other countries is not yet what it could be.
- The collection of critical-water-quality and water-use data is too often lagging and not harmonized.
- It takes time for countries to work through internal divisions to try to coordinate their internal policy actions or cross-boundary river treaties.
- Water access and infrastructure really need improvement in many places, including in the advanced economies of Europe and the United States.
- Higher water prices are needed to curb water overuse, allocating it better and spurring innovation and the adoption of technologies such as desalination.
Governments and institutions have only started a conversation on pricing water properly, and how to do it effectively within a legal framework that takes into account social inequities and economic efficiency.
The Role of Business and Society Solving Water Challengers
In the context of increasingly ambitious, yet incomplete and sometimes deficient public policy, there is ample room for civil society to play a role tackling water challenges. Nonprofit and philanthropic organizations may not have the vast resources and regulating power of governments, but they surely can inspire and show how interventions can make a difference. Companies are also influential players in the water space that can be allies in helping to move the needle in matters of sustainable water use.And water centers and institutes can bridge the gap between academia and practice. The new issue of EuropeNow, therefore, includes perspectives from several practitioners in these sectors:
- Chris Long, an NFL football player and founder of the Waterboys initiative, lends his name and energy to bringing wells to rural Tanzania.
- Alexis Morgan provides the perspective of the World Wildlife Fund, a global nonprofit that was founded over 50 years ago in Switzerland, and discusses why it cares about water and how it seeks to engage major companies to reach common goals.
- Fernando Mercé, CEO of Nestlé Waters North America, lays out how concerns about water shape a multinational such as Nestlé, which has its international headquarters in Europe.
- Multiple water centers and institutes are featured, including Oxford’s Water Network, Stanford’s Water in the West, The Pacific Institute, The Water Footprint Network and IHE Delft Institute for Water Education in the Netherlands, The Columbia Water Center, University of Copenhagen interdisciplinary water activities, the Stellenbosch Water Institute in South Africa and the UVA Global Water Initiative hosted by Darden.
Take the example of former University of Virginia football Chris Long, now a popular player for the NFL’s Philadelphia Eagles. He raises funds to dig solar-powered wells in Tanzania, and, in doing so, inspires both young and old NFL fans and others. He and fellow NFL players lend their celebrity status to a cause that, unfortunately, still does not attract enough attention and funding.
Long strives to also begin a conversation about water issues in the United States and abroad. He is gradually seeking to connect with stars in other sports, like basketball, about water. In a sense, that is exactly what the more than a dozen water centers, institutions, academics and practitioners who contributed their thought leadership to the special water issue of EuropeNow are trying to do. Together, we are seeking to advance the conversation around global water challenges into every industry and every sector of society.
Much like the interrelated challenge of climate change, this pursuit comes about because no industry or sector is immune to the consequences if we do not develop insights and solutions together.
This article and the double issue of EuropeNow hopefully frame the global water challenge, but they are also calls to action. The challenge is complex. The knowledge we need to act is multidisciplinary. The solutions are collaborative.
