We are living in historic moments in the world’s response to climate change. Last December in Paris, delegates from 196 countries signed an agreement to work towards curtailing greenhouse gas emissions and to keep global warming to “well below” 2 °C degrees. This is a big step, but there is still much work to be done and the agricultural sector has an important role to play. Agriculture, forestry, and land degradation contribute just under a quarter of anthropogenic GHG emissions, mainly from deforestation and agricultural emissions from livestock, soil and nutrient management. Climate change also poses a great challenge for food security and nutrition. It can reduce yields and affect where and how food is produced. As the risks of natural disasters increase, farmers need to modify how they produce food in order to become more resilient to prolonged droughts, excessive rains, floods, and more intense storms.

Now that the ice has finally melted and most of us have our power back on, it’s time to start evaluating the effect of the mega winter storm that screamed through the Southern Plains right after Christmas.
As a brief recap, winter storm Goliath hit the Southern Plains on December 26 through 28 leaving in its wake record snow fall in parts of Texas, power outages from ice accumulations of over one inch in parts of Oklahoma, and freezing rain and sleet in Kansas. Record flooding occurred throughout the Southern Plains making December 2015 the wettest on record for most of the region. It’s been estimated that over 40 people were killed by this storm (many coming from the Southern Plains region), making it the deadliest weather system recorded in 2015. The storm spawned 24 tornadoes, numerous flooding events, and left hundreds of thousands without power. Read more »
When thinking about how to reduce run-off from potato fields in New Brunswick, Canada, researcher Josée Owen of Agriculture and Agri-Food Canada turned to a tool created by Mike Dosskey, a U.S. Forest Service researcher at the USDA National Agroforestry Center.
With others at the University of Kentucky and the Forest Service, Dosskey created AgBufferBuilder, a GIS-based computer program used for designing vegetation buffers around agricultural fields. Soil can erode, and fertilizer and pesticides off of fields while suspended in water. Buffers with trees, shrubs and other plants help to filter this water by trapping sediment and nutrients.

Drought patterns have always fluctuated and are expected to become increasingly dynamic in the years to come, making managing working lands profitably more of a challenge. Because specific actions for building resilience to drought vary with location and forest type, USDA is helping land managers connect with experts and find region-specific information and tools through the USDA Climate Hubs.
Recent historical drought events vary from region to region, with the western U.S. showing a trend toward dry conditions while trends in the East are more complex. So how can land managers mitigate the impacts of drought on their lands? Read more »
At the beginning of this year, we launched a year-long reflection on USDA-wide results achieved over the course of this Administration. This week begins a month-long focus on seven years of USDA accomplishments to preserve our natural resources for tomorrow’s generations – accomplishments that have only been made possible with the hard work of our staff at USDA and the support of our steadfast partners.
I’m proud of the work that we’ve done to build lasting partnerships to care for our nation’s unparalleled public lands and support producers as they conserve our nation’s land, water and soil. Please take some time to read a full story of our results on my Medium page at: www.medium.com/usda-results. Read more »
Forest Service Drought Report Serves as ‘Foundation of Understanding’ for Forest, Rangeland Managers in a Changing ClimateBy
Drought is inevitable, a recurring natural event – or series of events – that can be felt over a season or a severe, longer lasting natural event that has social and economic consequences.
But how land managers prepare for or react at any stage of a drought in today’s world with the increasing effects of climate change and the information they use is the focus of a new report by the U.S. Forest Service, Effects of Drought on Forests and Rangelands in the United States: A Comprehensive Science Synthesis. The exhaustive report evaluates appropriate ways to quantify and monitor drought, assesses consequences for forests and rangelands, and identifies potential adaption strategies. Read more »
