Exploring New Options for Agroforestry

A Dust Bowl era poster urged farmers to plant windbreaks.

A Dust Bowl era poster urged farmers to plant windbreaks.

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.

The language on the 1930s poster for the Prairie States Forestry Project was downright plaintive: “Trees Prevent Soil Erosion/Save Moisture/Protect Crops/Contribute to Human Comfort and Happiness.”

The mission of the project, initiated by President Franklin Roosevelt, was to encourage landowners to plant tree windbreaks on cropland ravaged by dust storms and drought. As a result, more than 210 million trees from North Dakota to Texas were planted in 18,500 miles of windbreaks, some of which still remain. Read more »

USDA Northeastern Regional Climate Hub Gets Ready to Help Producers, Forest Managers, Deal with Challenges

If you work outside, you care about the weather. But if your business depends on the weather, you should care about the climate.

Those of us who have lived in the Northeast for years know that something is up with the weather.  It’s more changeable; too wet one month, too dry the next.  Spring is coming earlier but late frosts linger and fall seems to stretch on.  This year’s cold winter reminds us of what winters used to be like.

Nanotechnology to be Discussed at Outlook Forum

Say it: nanotechnology.

The word alone sounds intriguing, futuristic. But what is nanotechnology?

In simple terms, nanotechnology is understanding and controlling matter on a molecular scale—at dimensions between approximately 1 and 100 nanometers. Read more »

Southwestern Climate Hub Helps Producers Cope with an Uncertain and Changing Climate

Those of us living and working in the Southwestern U.S. have recently experienced a prolonged, extreme drought persisting over several years. We have witnessed large, destructive and catastrophic wildfires that have taken both lives and property, observed expansive areas of forest tree death as a result of massive insect outbreaks, and seen our water supplies in reservoirs and dams across the region decline to previously unseen levels. Yet, what can we realistically do in the face of these climatically driven changes that will likely continue and intensify into the future?

Changing climatic conditions in the southwest that impact temperatures, alter growing seasons, increase plant moisture stress, and trigger extreme events directly contribute to these recent regional catastrophes and water scarcities.  Recently, a highly respected, third generation public land cattle rancher in our region put it this way: “I believe that the climate is changing.  But I can’t accept it.  If I do I would just go out of business.  I have to cope and go on.”  So we are left to look around us and ask what information, tools, and technology can we reach for when it gets tough?

USDA Scientist Eager to Lead New Initiative to Combat a Devastating Citrus Disease

When I learned I was chosen to lead USDA’s new emergency, multi-agency response framework to combat one of the most serious citrus diseases in the world, I felt both humbled and honored.  I relish the opportunity as a scientist to partner with other federal agencies, states, and industry to combat a disease—huanglongbing (HLB or citrus greening)—that has devastated so many citrus groves in Florida and threatens other citrus-producing states.

When Secretary Vilsack established this new framework—USDA’s HLB Multi-Agency Coordination (MAC) Group—he directed us to fund the most promising, practical research to give growers tools to use against HLB as quickly as possible.  USDA provided $1 million in funding, and the 2014 Federal budget includes an additional $20 million for HLB research, which the Group will collectively determine how best to spend.

Consortium Uses Innovative Research to Tap Key Groundwater Source for Rural Region

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.

As a major underground water source, the Ogallala Aquifer plays a key role in the economic vitality of vast stretches of the rural Midwest.  The aquifer covers around 225,000 square miles in 8 states from South Dakota to Texas, supplying 30 percent of all U.S. groundwater used for irrigation.

But as with other natural resources that seem inexhaustible, the aquifer is effectively a nonrenewable resource. Demand from agricultural, municipal and industrial development on the Great Plains has meant that water is pumped out of a large portion of the aquifer much more quickly than it can ever be replenished.
