Water is a scarce resource in India, especially in the state of Maharashtra, where most rainfall is limited to the monsoon season from June through September. The Government of India has long promoted a Participatory Watershed Development (PWD) approach to deal with this scarcity.

Natural ecosystems provide essential services for our communities. Forests and wetlands, for example, filter the water we drink, protect neighborhoods from floods and droughts, and shade aquatic habitat for fish populations.
While nature provides this “green infrastructure,” water utilities and other decision-makers often attempt to replicate these services with concrete-and-steel “gray infrastructure”—usually at a much greater cost. Particularly where the equivalent natural ecosystems are degraded, we build filtration plants to clean water, reservoirs to regulate water flow, and mechanical chillers to protect fish from increasing stream temperatures. And even though healthy ecosystems can reduce the operational costs of these structures, investing in restoring or enhancing various types of green infrastructure is rarely pursued—either as a substitute for or complement to gray infrastructure.
Despite America’s history of reliance on gray infrastructure, now is a critical time to tip the scales in favor of a green infrastructure approach to water-resource management. Investing in the conservation and improved management of natural ecosystems to secure and protect water systems can keep costs down and create jobs. Green infrastructure can also provide a suite of co-benefits for the air we breathe, the places we play, the wildlife we share our landscapes with, and the climate we live in.
The Mekong River Basin (MRB) Study provides details of the data, sources, methodology, and maps for 14 water-related indicators across the Mekong River Basin in Southeast Asia. The MRB Study is primarily designed for research organizations for analysis and research purposes.
Water supply and availability could be the most pressing problem restricting China’s economic growth in the next 10-15 years, according to a new report by the Asian Development Bank. Not only are water resources limited (only about 30 percent of total water resources are available for use), but many surface and groundwater sources are suffering from severe pollution.[^1] The Chinese government is now looking to invest in new ideas to improve water quality and supply, and WRI is using its water quality trading expertise to explore the potential of market-based methods to improve water quality and increase the supply of clean water from Chao Lake, the fifth-largest lake in China.

Forested watersheds of the southern United States provide numerous services to the region. At no cost, they purify water, control flooding and erosion, and provide places for people to relax and have fun. Yet despite their value, many watersheds are under threat from development and poor land management.
“Payments for Watershed Services” (PWS) programs are one strategy to keep watersheds healthy. Through a PWS program, landowners receive financial incentives to conserve, sustainably manage, and/or restore watersheds to yield the kinds of benefits described above.
Using markets to protect and restore ecosystems – and the many services they provide – is gradually becoming a reality. Market-based systems have already protected hundreds of thousands of acres of land while still meeting human economic and development needs. They can help ensure that environmental benefits, from wildlife habitat to water purification, will be preserved for future generations.
But what are the critical elements for success? What progress has been made? What are the innovative ideas that will push these markets forward? The World Resources Institute and the American Forest Foundation recently convened some of the world’s leading experts on ecosystem markets in Madison, Wisconsin to address these questions.
2011 will be an important year for the Chesapeake Bay, not only because scientists are predicting an unusually bad “dead zone” this summer.
Last December, the Environmental Protection Agency (EPA) issued total maximum daily loads (TMDLs) that establish the amount of nutrient and sediment pollution that the Bay and its tidal tributaries can safely receive each year. The TMDLs divide the pollution loads among sources, such as urban areas regulated for stormwater runoff, wastewater treatment plants, and agricultural lands.
Now, responsibility for implementing the TMDLs falls to states in the Bay watershed that have been delegated authority from EPA to run water quality programs. By December 1, 2011, Delaware, Maryland, New York, Pennsylvania, Virginia, and West Virginia will submit plans to EPA that explain how sources within their jurisdiction will meet and maintain the TMDLs.
The December deadline has states reviewing legislation and regulations that could reduce the amount of nutrient and sediment pollution that impairs Bay water bodies.

In August of 2010, the Indian electricity company Satluj Jal Vidyut Nigam Ltd (SJVN) lost its source of power in Himachal Pradesh. Deforestation and river alterations upstream of the company’s dam had aggravated erosion in the area. Without the trees, heavy rains washed an unprecedented amount of sediment straight into the water, lowering dam reservoir capacity and power output. The resulting 22 days of closure for the facility left millions of people without power and cost the company upwards of $42 million, or INR. 198 Crore.
Wisconsin is a state blessed with abundant natural beauty and was home to one of America’s first conservationists, Aldo Leopold. Leopold recognized that beyond commodities, nature provides services that sustain our planet – such as clean air, clean water and recreational opportunities – and that these services are worth something. He also recognized the importance of providing incentives that reward proper land management. Leopold’s vision still resonates as the 4th annual Ecosystem Markets Conference takes place this week in Madison, Wisconsin.
