Water is essential for human life. It is also very useful for transportation, and agricultural and industrial production. Energy is also an essential ingredient. The relationship between these two resources has become an important topic for national security and for human development worldwide. With current available technology, vast quantities of water are required to produce energy (thermoelectric production as an example). Moreover, due to the geographical mismatch of water supply and demand, a significant amount of energy is needed to transport water where it is consumed, and to ensure that it has the proper quality for its different end uses (human consumption, agricultural uses, industrial production, and ecosystems protection).

Water covers 70.9% of the Earth’s surface. However, only 3% of the Earth’s water is freshwater, and 68.7% of this freshwater is in glaciers, 30% is ground water, and 0.3% is surface water. Humans depend on freshwater for a wide variety of uses, and this finite amount of water must be properly managed and allocated.
The chart below shows the uses of freshwater in the U.S. The chart highlights the nexus between water, food, energy –the focus of the upcoming Wharton IGEL Conference on March 20-21, 2013. The two leading uses of freshwater withdrawals in the U.S. are thermoelectric power and irrigation, and any significant change in water use in these sectors will likely have an impact on the other categories.
How do droughts affect our country? As part of a group project for the Wharton course Risk Analysis and Environmental Management, Penn students Sharon Muli, Brent Ginsberg, Zenia Zelechiwsky, and Yaowen Ma are gathering data on how individuals perceive the risk of drought. The focus of this project is to investigate the likelihood of more droughts occurring in the United States in the future and to shed light on their associated impacts.

I started working on this project last semester, while taking a course in environmental economics.
As a subfield of economics, environmental economics draws on both microeconomics and macroeconomics[i], but it also has unique concepts of its own. I have seen that students who have never studied economics before can find terms like “property rights” and “marginal abatement cost” overwhelming. While scholars of economics often use historical data and experiments, environmental economics is a relatively recent discipline, developed first in 1950s in the U.S.[ii] There aren’t many experiments to build upon; for instance, the water rights trade doesn’t have a large scope of application, except for some arid areas like California and Australia. So how are students supposed to fully understand and apply these concepts in the real world?
I learn best through direct experience. This type of teaching doesn’t seem boring to me. And in fact, it is suggested that people do have a better memory when they put teachings into practice, for example, by trying to cook a meal rather than just reading its recipe. This is why I want to create a game about environmental economics. Continue reading

On February 8, 2013, with an imminent Winter Storm Nemo on the horizon, over 250 industry leaders and key players in the water sector came together at Goldman Sachs in New York City to begin the dialogue on addressing water risks throughout the country. Students from the Master of Environmental Studies at the University of Pennsylvania joined the Wharton Initiative for Global Environmental Leadership (Wharton IGEL) team in attending this event to gain key perspectives from leaders in the water sector. Entitled “Water: Emerging Risks and Opportunities Summit,” the conference identified areas in need of improvement and discussed opportunities from various points of view. A welcoming address from David Solomon, Co-Head of the Investment Banking Division at Goldman Sachs, established the overall goals of bringing together capital, technology, and policy in order to determine best management practices within the water sector.

The global population is projected to hit eight billion people within 20 years. With a growing population, dramatically more food, water and energy is needed. Yet even today, food and water supplies are becoming increasingly stressed in the face of climate change, development and unsustainable natural resources consumption. Recent drought-caused food price hikes have provided a glimpse into what the resource-constrained future would look like without significant action.
The concept of the food-water-energy nexus refers to how each one of those things affects the other. Water is the most important part of this nexus, because it cannot be created or substituted. Water also directly affects both of the other items. For example, most forms of energy production require substantial amounts of water for cooling and mining. Agriculture accounts for more than 70 percent of global water withdrawals. By comparison, around 16 percent of global water withdrawals are for the industrial sector. More than three billion people will be living in water-stressed areas by 2020. Continue reading

Save the date for IGEL’s Sixth Conference-Workshop on “The Nexus of Energy, food, and Water”, to be held on Thursday, March 21st, 2013. Objectives of the conference include providing an overview about sustainability as it relates to energy, food, and water, the multitude of strategies needed to evaluate water risk in the global economy, as well as the intersection between energy resources, food supply, and security. Speakers will include Andrew Winston, author of “Green to Gold”, Jeff Seabright of Coca-Cola, Perry Moss of Rubicon Global, Tamara Thies of the National Cattlemen’s Beef Association, and many more. The keynote address and prelude to IGEL’s conference-workshop will be delivered by General John Ashcroft, followed by a VIP Dinner the night before, Wednesday, March 20th, 2013. For more information, please view the conference agenda.
