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.

During the month of April we will take a closer look at USDA’s Groundbreaking Research for a Revitalized Rural America, highlighting ways USDA researchers are improving the lives of Americans in ways you might never imagine.

Over the past several decades, satellite imagery has emerged as one of the most valuable new tools in modern agriculture. At USDA’s National Agricultural Statistics Service (NASS), we strive to remain at the forefront of this technology to continually advance our statistical products in service to U.S. agriculture. To keep abreast of how our counterparts in other countries are implementing this exciting new technology, last month we hosted representatives from the Canadian and Mexican agriculture departments in a Tripartite meeting. As geographic neighbors and statistical collaborators, we are particularly interested in each others’ work and how we can learn from each other.

It was exciting to see that Statistics Canada, working with Agriculture and Agri-food Canada, is researching new remote sensing-based yield models, using vegetative indices, agro-climactic data, and survey data for 21 crops. As a result of this innovation, Stats Canada is planning to use only remote sensing to set their official estimates for these crops rather than conducting traditional surveys. This is a tremendous step forward for a statistical estimates program that we will be watching with great interest.

In Mexico, our counterparts at the National Institute of Statistics and Geography conducted a ground survey campaign to identify field crops and performed crop classifications to identify sorghum, maize, and lemons in various parts of Mexico and worked with their NASS and Statistics Canada colleagues to characterize vegetation condition indices. At the same time, our colleagues at the Mexican Agrifood and Fisheries Information Service used Moderate Resolution Imaging Spectroradiometer (MODIS) Normalized Difference Vegetation Index (NDVI) for drought monitoring and are researching vegetation indices and how they relate to yield.

On NASS’ end, we discussed our remote sensing models for corn and soybean yields using NDVI and daytime surface temperatures from MODIS. We also discussed the current and future status of the Landsat program and demonstrated how to access the free data. I presented an overview of the Cropland Data Layer (CDL) and how we continue to evolve and update this program. I have previously discussed in this blog our satellite imagery progress and tools, such as CropScape, which we have developed in partnership with George Mason University. We continue to update that tool and have recently made available 2013 geospatial data for U.S. crops.

Having seen how remote sensing and geospatial programs are implemented by our international neighbors reminded us once again that progress does not stand still. We can learn a great deal from each other. Going forward, we hope to continue to push the boundaries of this technology to enhance our statistics and ensure easy public access to interactive visualizations of U.S. agriculture.

EPA Awards $175,000 to the Cherokee Nation to Support Its Water Quality Program

Press release:

EPA Awards $175,000 to the Cherokee Nation

to Support Its Water Quality Program

(DALLAS – July 11, 2012) The Environmental Protection Agency has awarded the Cherokee Nation of Oklahoma $175,000 to provide continued support for the Tribe’s water pollution control program. The funds will be used to take water samples to assess surface water quality on Tribal lands and compile data which may show changes over time and to determine if a more thorough watershed management program is needed. Sampling data will determine whether water quality standards are being met, note any changes in the quality or condition of the Cherokee Nation’s water and provide planning tools to improve the function and health of stream ecosystems.

The mission of the EPA is to protect public health. The EPA supports our nations’ tribes in all aspects of the work needed to improve the water quality of tribal land watersheds. This cooperative spirit supports work to protect water quality that ensures the health of watersheds that cross state and tribal boundaries.

News Release from EPA Region 2

EPA Funding Available for Study of Raritan River in NJ

Contact: Mary Mears (212) 637-3673; mears.mary@epa.gov

(New York, N.Y. – March 13, 2012) The U.S. Environmental Protection Agency is encouraging applications for $100,000 in funding to study contaminated sites and other sources of pollution that are impacting water quality in the lower and middle Raritan River. This funding is part of an EPA Raritan River Initiative, which will support the analysis of existing data to enable environmental agencies, institutions, community groups and local governments to identify data gaps, plan future research and make other environmental decisions.

The Raritan River runs from west of Somerville, N.J. into the Raritan Bay. The river and the surrounding watershed is home to over one million people, providing drinking water, transportation and recreation opportunities and important habitat for wildlife. The watershed is impacted by many sources of pollution, including contaminated sites, industrial facilities and sewage treatment systems. While there is sampling data collected within the Raritan River watershed, this information is fragmented.

“This funding demonstrates the EPA's continued commitment to a cleaner and healthier Raritan River and the health of everyone who enjoys it," said EPA Regional Administrator Judith A. Enck. "The data and information collected will help Raritan River communities better understand pollution that has affected river conditions and will assist in decision-making on the best ways to improve water quality.”

Using the funding, the selected applicant will identify high priority sites and sources of pollution that are potentially impacting the river. The resulting site list and associated data will then be made available to the public and put into a format that can be used by state agencies, country and local governments, non-profit organizations and other stakeholders to make environmental decisions. The data would also be used to create an interactive website to show exact locations of potentially polluting sites along the river along with the data for each site.

All applications are due no later than April 23, 2012 at 5:00 p.m. EDT. Additional information on the grants, including guidance on eligibility and procedures for applying, is available at http://www.epa.gov/region2/grants/ or through http://www.grants.gov.

EPA to Provide Funding for Beach Cleanup

News release from EPA:

FOR IMMEDIATE RELEASE
January 31, 2012

EPA To Provide Nearly $10 Million to Clean Up Beaches Across the Nation

The agency launches improved website for beach advisories and closures

WASHINGTON – The U.S. Environmental Protection Agency (EPA) today announced that it will provide $9.8 million in grants to 38 states, territories and tribes to help protect the health of swimmers at America’s beaches. The agency also launched an improved website for beach advisories and closings, which will allow the public to more quickly and easily access the most current water quality and pollution testing information for more than 6,000 U.S. beaches.

The website, called BEACON, has the capability to update as frequently as every two hours based on new data provided by states, territories and tribes. Users will have access to mapped location data for beaches and water monitoring stations, monitoring results for various pollutants such as bacteria and algae, and data on public notification of beach water quality advisories and closures. For the first time, users can also access reports that combine notifications and water quality monitoring data. The enhanced system also uses enhanced map navigation and report display tools.

The majority of beach advisories and closures in the United States are due to water test results indicating bacterial contamination, which can make people sick. Bacterial contamination comes from a variety of sources. Some examples are sewer overflows, untreated stormwater runoff, boating wastes, wildlife and pet waste, and malfunctioning septic systems.

During each swimming season, state and local health and environmental protection agencies monitor the quality of water at the nation’s beaches. When bacteria levels in the water are too high, these agencies notify the public by posting beach warnings or closing the beach.

The grants will help local authorities monitor beach water quality and notify the public of conditions that may be unsafe for swimming.

This is the 12th year that EPA is providing beach grant funds, bringing the total amount EPA has made available to nearly $111 million. As a result, the number of monitored beaches has more than tripled to

more than 3,600 in 2010. Grant applications must be received within 60 days of publication of EPA’s notice in the Federal Register. EPA expects to award the grants later this year.
