The Chesapeake Bay is a valuable resource. The Bay is home to a variety of species, such as blue crab and striped bass, provides jobs for local fishing communities, and serves as a place to interact with nature. About a quarter of the land in the Chesapeake Bay watershed is devoted to agriculture. The crops and livestock produced in this region provide food and fiber for millions of Americans. But these agricultural lands do more than produce food—they can play a role in improving the Bay’s water quality.
In 2010, the Environmental Protection Agency (EPA) worked with the Bay states to set water quality goals for the Chesapeake Bay and to develop Watershed Improvement Plans, or “WIPs,” for each of the states. Read more »

Running an economical and environmentally friendly dairy operation is a tough job but Andreas Farms is dedicated to meeting the challenge. That challenge involves running an efficient milking operation of more than 1,500 dairy cows while also managing tons of animal waste.
Dan Andreas is a dairy man who runs the successful operation that produces 38 million pounds of milk each year, and he’s a conservationist who strives to protect his hometown’s watershed. The East Branch South Fork Sugar Creek watershed is one of three priority Ohio watersheds that are in critical need of water quality improvements. Read more »

This post is part of the Science Tuesday feature series on the USDA blog. Check back each week as we showcase stories and news from the USDA’s rich science and research portfolio.
There’s no farming without water. Recent droughts in the United States and elsewhere underscore our need to conserve water in agricultural production, and studies have identified agricultural management practices that help protect water quality. USDA’s Agricultural Research Service (ARS) researchers are making key contributions to these efforts.
For instance, ARS scientists use moisture information collected by satellites to develop the Evaporative Stress Index. In 2012, this tool predicted that drought conditions were developing weeks before other drought monitoring networks made the same call. ARS researchers also use satellite data to design methods of estimating rainfall amounts in regions where setting up sampling stations would be a challenge, work that has long-range potential for improving precipitation estimates globally.

This month USDA will be highlighting the value of conservation with a different focus each week.
Sometimes the benefits of conservation can be abstract. For example, think a minute about the dollar value of a single tree. Can you come up with a number?
Did you consider that the tree creates oxygen, captures carbon and provides wildlife habitat? Or that the tree serves as a windbreak, shades and cools the surrounding area, and improves water quality? Don’t forget, these benefits extend for many decades over the lifetime of a healthy tree.

A nonprofit for sustainable agriculture recently launched a new metric in its calculator that relies on a popular tool from USDA’s Natural Resources Conservation Service.
Field to Market, the Alliance for Sustainable Agriculture, recently updated its Fieldprint Calculator that measures outcomes in the field to include a metric to measure water quality. This metric relies on NRCS’ Water Quality Index for Agricultural Runoff, or WQIag, which enables farmers to input variables about their field, such as slope, soil characteristics, nutrient and pest management, tillage practices and conservation practices to calculate impact on water quality.

Staff members from the Alliance for the Chesapeake Bay and the Maryland Forest Service advise a forest landowner on options for how to participate in a water quality trading system.
Government agencies and organizations in Pennsylvania, Maryland and Virginia have been building water quality trading systems during the past few years to lower the cost of regulatory compliance with water quality laws.
These trading systems enable farmers, ranchers and forest landowners in these Chesapeake Bay-area states to generate income by selling water quality credits to regulated entities like waste water treatment facilities and developers. As this market matures, people will be able to incorporate clean water into their overall management objectives more seamlessly.
The Alliance for the Chesapeake Bay, with funding from a USDA Conservation Innovation Grant, is developing tools to make it easier for people who own or manage forests to offer up their forested land for possible water quality and other ecosystem service credits. The alliance is working to streamline the credit development process for water quality trading on forested land in the region. Read more »
