Chesapeake Bay Executive Order
Protection and Restoration

Targeting Resources to Better Protect the Chesapeake Bay is Aim of U.S. Department of Agriculture's 202(b) Report

August 20 2009

Executive Order 13508, Chesapeake Bay Protection and Restoration, issued a call to action to harness public and private resources “to protect and restore the health, heritage, natural resources, and social and economic value of the Nation’s largest estuarine ecosystem.” Section 202(b) of the Executive Order directs the U.S. Department of Agriculture (USDA), in coordination with other federal, state, and local stakeholders to develop recommendations for targeting resources to better protect the Chesapeake Bay and its tributaries.

An essential economic engine, the Bay watershed supports significant agricultural, forest, fishery, and tourism sectors. In 2004, the Chesapeake Bay Watershed Blue Ribbon Finance Panel observed that the economic value of the Bay may be over $1 trillion annually, but noted that the experiential and deep historical and cultural values of the Bay are beyond calculation.

While agriculture and forestry remain the predominant land uses in the watershed – accounting for nearly 75 percent of the Chesapeake Bay Watershed – these lands are increasingly being converted to developed uses.  Between 1982 and 2003, nearly 2 million acres of crop, pasture, and forest land were converted to large and small built up areas –an area greater than the entire state of Delaware. About 12 percent of the land in the Chesapeake Bay Watershed is now classified as developed, up from 8 percent in 1982. Approximately 130,000 new residents move to the Chesapeake Bay Watershed each year, driving a continuing market for housing and development.

In addition to population growth, other pressures leading to agricultural land conversion include the economic viability of agriculture, complexity of doing business in the rural–urban interface, diminishing access to agricultural infrastructure, and increasing cost of regulatory compliance. As previously rural watersheds shift from agricultural to developed uses, the fabric of the community changes leading to further conversion of agricultural and forest areas.

Multiple impacts are associated with conversion of agricultural and forested areas to developed uses. “Food deserts” may be created as access to local, fresh foods declines. Carbon capture in agricultural and forestland vegetation and soils diminishes. Impervious surfaces – such as roads, roofs, and shopping malls – increase. Once impervious surfaces cover more than 10 percent of a watershed, the rivers, creeks, and estuaries begin to degrade biologically. Consider that a one-acre parking lot produces about 16 times the volume of runoff that comes from a one-acre meadow

Agriculture covers about 25 percent of the watershed, representing the larges intensively managed land use.  There are an estimated 87,000 farms covering about 8.5 million acres.  While fertilizers, pesticides and manure and tilled soil are beneficial to crops, they become pollutants when water from irrigation and precipitation washes them into local waterways from unprotected fields.  Substantial investment over the past several decades has helped to put conservation in place throughout the Chesapeake Bay Watershed.  Through a partnership approach, Agriculture has achieved 50 percent of the goal for agriculture nitrogen, a 2 percent increase from 2007.  About 49 percent of the goal for agricultural phosphorus control efforts have been met a 2 percent decline from previous years.  Partners have achieved 48 percent of the goal for sediment pollution control efforts, the same as 2007.  These estimates do not account for all of the best management practices installed voluntarily by private landowners with the use of public funds. 

The challenge ahead is substantial, but one thing is clear – losing farms and forests is not in the best interest of the Chesapeake Bay ecosystem.  Agriculture can and does make a positive contribution to sustaining natural resources in the Chesapeake Bay Watershed, from preserving open space and providing wildlife habitat to generating water quality improvements to help meet established water quality goals

An aggressive, voluntary partnership approach is called for, working with farmers, foresters, and other private land managers to continue to improve water quality while sustaining agriculture as a valued component of the Chesapeake Bay Watershed. This approach, while focused on water quality, must also include dimensions of increasing farm viability and rural wealth, strengthening access to local foods for well-nourished communities, and protecting the ecosystem benefits that make the Chesapeake Bay Watershed a national treasure.
