Changes in a Key Source of Honey Bee Nutrition

All this month we will be taking a look at what a changing climate means to Agriculture. The ten regional USDA Climate Hubs were established to synthesize and translate climate science and research into easily understood products and tools that land managers can use to make climate-informed decisions. The Hubs work at the regional level with an extensive network of trusted USDA agency partners, technical service providers, University collaborators, and private sector advisers to ensure they have the information they need to respond to producers who are dealing with the effects of a variable climate. USDA’s Climate Hubs are part of our broad commitment to developing the next generation of climate solutions, so that our agricultural leaders have the modern technologies and tools they need to adapt and succeed in the face of a changing climate.

Honey bee health and climate change would both rank high on anyone’s list of hot topics in agriculture these days.

Lewis H. Ziska, an Agricultural Research Service (ARS) plant physiologist, with what is part of the Northeast Climate Hub in Beltsville, Maryland, knows this. He also knows that any study involving both honey bees and climate change should be carefully conducted and cautiously interpreted.  Ziska has been studying the effects of climate change on plants since 1988. He has been focusing on how rising atmospheric carbon dioxide (CO2) levels accompanying climate change are affecting a wide range of plants—from important food crops to noxious weeds. Read more »

Helping Agriculture Producers Adapt To Climate Change from the Ground Down

USDA’s Climate Hubs are part of our broad commitment to developing the next generation of climate solutions, so that our agricultural leaders have the modern technologies and tools they need to adapt and succeed in the face of a changing climate.

The Southern Great Plains has historically posed a challenge to farming and ranching.  Extended drought, late season freezes and excessive rainfall are facts of life in Texas, Oklahoma and Kansas.  With continued climate change, the likelihood is growing that extreme weather conditions will have even more of an effect on the country’s ability to produce food and fiber as we move into the future.  It’s paramount the nation’s farmers and ranchers are given tools to develop strategies to help weather the storms and maintain the productivity and profitability necessary to stay on the land.

The USDA Southern Plains Climate Hub (Hub), along with USDA’s Natural Resources Conservation Service (NRCS) and Agricultural Research Service (ARS), Redlands Community College, the region’s Agricultural Universities and other partners have been working to develop best management practices designed to help ag producers adapt to intense weather events through improving soil health.  This includes the establishment of demonstration farms that implement soil health practices such as no-till, cover cropping and better pasture management.  As a result of conducting field days and soil health seminars associated with these demonstration efforts, the Hub and its partners are providing real world examples of how implementing these soil health practices can help agriculture “harden” itself to extreme drought, volatile temperature swings and heavy rain events.

A Tree in a Time Capsule

Gene Conservation poster

The U.S. Department of Agriculture (USDA) hosts a free workshop on gene banks for conservation of tree species in Chicago, IL, May 16-19, 2016. Details are available at www.fs.fed.us/geneworkshop.

The story of Super Girl being placed in a pod on Krypton and fired off to earth to help save her cousin and at least some of her species is science fiction. But for many species the danger of extinction from climate change, habitat destruction, or invasive exotic pests is the real deal.

At an upcoming Gene Conservation Workshop experts will discuss different ways to safeguard species from climate change and other threats. For forest tree species that are experiencing rapid declines due to invasive exotic pests or climate change, long term seed storage is our best hope so that they can be returned to the wild once a control is found.

Bringing up Better Biofuel

The idea of replacing fossil-based fuel, such as petroleum, with a renewable energy source is enough to get any environmentalist excited. Now, Agricultural Research Service (ARS) scientists have advanced a process to produce crude liquid fuel called “bio-oil” from agricultural waste. The bio-oil is produced by a process called “pyrolysis,” which involves chemical decomposition of plant and other organic matter at very high heat without oxygen.  This new technology for producing renewable fuels is called “tail-gas reactive pyrolysis” or TGRP.

The TGRP method might be considered a new generation of pyrolysis because it holds promise for processing and improving bio-oil as an intermediate product toward finished biofuel. Read more »

Wheat Blast, Bangladesh, and Biosecurity: NIFA-Funded Research Works for Global Food Security

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.

An epidemic of wheat blast is underway in Bangladesh, published reports say, and losses may be substantial in the six southeastern districts where it has been reported. Wheat blast is a crop disease caused by the Triticum pathotype of the fungus Magnaporthe oryzae (MoT). In nations where broad wheat blast epidemics have occurred, 30 percent losses have been noted, but localized areas have experienced 50-100 percent losses, according to Dr. Barbara Valent, fungal molecular geneticist at Kansas State University (KSU).

The U.S. Department of Agriculture’s (USDA) National Institute of Food and Agriculture (NIFA), through its Agriculture and Food Research Initiative (AFRI), has provided nearly $5.4 million since 2009 to support research on wheat and rice blast. KSU leads a multi-institutional research project that brings together expertise from University of Arkansas, University of Kentucky, the Ohio State University, Purdue University, and USDA’s Agricultural Research Service.
