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.
The future of farming, food supply, and protection of natural resources are utterly interdependent.
While all economic sectors depend to some degree on ecosystem services, agriculture has the most intimate relationship with nature. Agriculture depends on healthy ecosystems for services such as pollination for nearly 75% of the world’s crop species, freshwater, erosion control, and climate and water regulation. It also employs 40% of global population and about 70% at the base of the pyramid.
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.
A new report on the state of the world’s oceans is gaining considerable attention this week. The report by the International Programme on the State of the Ocean (IPSO) and the International Union for the Conservation of Nature warns that combined threats to oceans are creating conditions where there is “a high risk of entering a phase of extinction of marine species unprecedented in human history.” Dr. Alex Rogers, scientific director of the IPSO, calls the new findings “shocking.”
