Selecting Trees to Grow in Cities: Database Captures Urban Tree Sizes, Growth Rates Across US

In the cramped environs of U.S. cities every inch counts, especially if attempting to make space for nature. But now city planners and urban foresters have a resource to more precisely select tree species whose growth will be a landscaping dream instead of a maintenance nightmare.

The U.S. Forest Service’s Pacific Southwest Research Station recently published a technical manual and launched the most extensive database available cataloging urban trees with their projected growth tailored to specific geographic regions. Read more »

Research in Energy Security Helps Lead to Food Security in West Africa

Cochran Fellows receiving training from the USDA Forest Products Laboratory

Cochran Fellows receive training from the USDA Forest Products Laboratory during a hands-on workshop on low-cost, high-efficiency cooking stoves. The stoves provide gains in efficiency, as well as reduce pollution offering benefits such as a lower incidence of pulmonary diseases.

Research shows the majority of people in Africa depend on biomass to meet their energy needs, with approximately 80 percent relying on wood energy. Such high dependency makes families vulnerable to unexpected and sudden changes, including extreme weather and socio-political events. Researching and developing ways to diversify energy sources is crucial for a more sustainable, food secure future.

A project funded through the USDA Foreign Agricultural Service (FAS) Cochran Fellowship Program on “Biofuels for Sustainable Rural Livelihoods,” hosted by the University of Missouri (MU) College of Agriculture, Food and Natural Resources International Programs, set out to address this very issue. The research and training program was organized for West African Cochran Fellows to learn how different uses of biofuels can help support sustainable livelihoods in their communities. The two-week-long program consisted of workshops, field visits and interactive discussions in cooperation with the USDA Forest Products Laboratory, the MU Center for Agroforestry, Columbia Center for Urban Agriculture and Envest Microfinance.

High-Tech Agriculture Continues to Reap Rewards for Farmers and Society

A team of researchers with an unmanned aerial system

With a new view from above, diverse teams of researchers help deliver information to farmers using useful, inexpensive unmanned aerial systems (UAS).

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 USDA’s rich science and research portfolio.

Just like a smart phone helps users learn, communicate and make important decisions, smart technology—known as precision agriculture—helps farmers know and apply critical information about the right investments in fertilizer, seed, pesticide and water needed to produce their crops. Through new technologies, farmers produce more efficiently and see an increase in profits while improving stewardship of ecosystems and local communities.

To talk about precision agriculture is to talk about mapping the amount of a crop grown per acre (yield) or the types of soils in a given area. It also includes the technology that automatically guides farm machines and controls variables like the rates of seeds, fertilizers or chemicals. Read more »

People behind Scientific Innovation at USDA

Dr. Woteki works with 4-H members.

The past eight years have been an extraordinary time for agricultural science, and for the application of new insights from other fields to enhance agricultural productivity and the overall agricultural economy. As the final days of this administration are approaching, it gives me a great deal of pride to look back at what USDA has accomplished in the areas of research and innovation.

Scientific research is a fundamental part of our mission at USDA. But, ultimately, what’s behind all the science is people – people who do the research and people who are affected by it. As USDA’s Chief Scientist and Under Secretary for Research, Education and Economics, I’ve met and worked with both as I’ve traveled across the country and around the world. Read more »

Unique Conservation Partnership Helps Create Win-Win Situation

By keeping their grasslands intact, two Colorado ranches are reducing greenhouse gas emissions and protecting vital wildlife habitat, all while earning additional revenue.

It may seem too good to be true, but it is thanks to a unique partnership spearheaded by the Climate Action Reserve, one of North America’s leading carbon offset project registries.

With the help of a Conservation Innovation Grant (CIG) from USDA’s Natural Resources Conservation Service (NRCS), the Climate Action Reserve listed Raven’s Nest and Heartland Ranch, both owned by the Southern Plains Land Trust (SPLT), as the first two grassland offset projects developed and executed under a new Grassland Project Protocol.

The Bio-Based Economy and Renewable Energy: USDA’s Record of Success

Bear Mountain Forest Products Owner Bob Sourek

Bear Mountain Forest Products plant owner Bob Sourek in Oregon produces BBQ pellets and home heating fuel pellets. Bear Mountain Bear Bricks (similar to firewood logs), and animal bedding are produced at the Cascade Locks facility.

One of the hallmarks of the Obama Administration has been our commitment to economic growth through an expanding bio-based economy.  Nowhere is that transformation more pronounced than the success of renewable energy.   And USDA Rural Development has been a leader in that effort.

The proof is in the numbers: Domestic energy-related emissions have fallen to their lowest level in 20 years.  Our dependence on foreign oil is at a 40-year low and declining. In the last eight years, USDA has helped lead an effort to promote the domestic production and use of advanced biofuels and biobased products, supporting millions of jobs and pumping hundreds-of-billions-of-dollars into the U.S. economy.
