The Fourth National Climate Assessment report, from the U.S. government’s Global Change Research Program, was just released. The report, prepared with the support and approval of 13 federal agencies, and with input from hundreds of government and non-governmental experts, provides an comprehensive look at how climate change will impact the United States. Read a statement by Dan Lashof, U.S. Director, World Resources Institute.

One cause is the controlled release of water from an over-full Lake Okeechobee into local rivers that flow east to the Atlantic and west to the Gulf of Mexico.

by Sara Walker - June 10, 2014For more than 30 years, the USDA has worked to reduce water pollution by offering farmers throughout the nation financial and technical help to put conservation measures in place. While these efforts have successfully addressed environmental problems at the individual farm level—such as soil erosion—agriculture remains a key source of water pollution.
However, it’s only a small portion of farms that generate the majority of agriculture’s contribution to U.S. water pollution. New research shows that targeting conservation funds to these farms with the most potential to reduce pollution could be up to 12 times more cost effective than the usual practice of disbursing funds widely. And encouragingly, a new USDA program aims to capitalize on a similar targeted approach.

by Michelle Perez - April 17, 2013The Gulf of Mexico has the largest dead zone in the United States and the second-largest in the world. Dead zones form when excessive amounts of nitrogen and phosphorous wash into waterways and spur algal blooms, depleting the water of oxygen and killing fish, shrimp, and other marine life. The Gulf of Mexico dead zone can range between an astounding 3,000 and 8,000 square miles. At its largest, it’s about the size of Massachusetts.
Reducing this growing dead zone problem is a huge scientific, technical, economic, and political challenge. It’s a conundrum that agricultural and environmental experts from across the United States will deliberate this week at the Gulf of Mexico Hypoxia Task Force meeting in Louisville, Kentucky.
One new approach they’ll discuss is voluntary nutrient trading. According to a new study conducted by WRI staff for the EPA, this strategy could be used in the Mississippi River Basin to cost-effectively reduce nitrogen and phosphorous pollution and shrink the Gulf of Mexico dead zone.

by Mindy Selman - October 10, 2012This year’s extreme weather events—a warm winter, even warmer summer, and a drought that covered nearly two-thirds of the continental United States—has certainly caused its fair share of damages. But despite the crop failures, water shortages, and heat waves, extreme weather created at least one benefit: smaller dead zones in the Chesapeake Bay and Gulf of Mexico.

As my colleague, Mindy Selman, noted in a recent blog post, “Agriculture is the leading source of nutrient pollution in waterways—a situation that’s expected to worsen as the global population increases and the demand for food grows.”

by Mindy Selman - August 23, 2012Our water systems are currently being threatened by the crops we grow and food we produce. In many countries, agriculture is the leading source of nutrient pollution in waterways—a situation that’s expected to worsen as the global population increases and the demand for food grows.

by Erin Gray and Cy Jones - May 15, 2012Water 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.

by Janet Ranganathan - August 09, 2011The 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.

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.”
