Neonicotinoid pesticides hinder wild queen bumblebee’s reproductive success, according to a new University of Guelph study.

While recent media reports have condemned a commonly used agricultural pesticide as detrimental to honey bee health, scientists with the University of Tennessee Institute of Agriculture have found that the overall health of honey bee hives actually improves in the presence of agricultural production.
The study, “Agricultural Landscape and Pesticide Effects on Honey Bee Biological Traits,” which was published in a recent issue of the Journal of Economic Entomology, evaluated the impacts of row-crop agriculture, including the traditional use of pesticides, on honey bee health. Results indicated that hive health was positively correlated to the presence of agriculture. According to the study, colonies in a non-agricultural area struggled to find adequate food resources and produced fewer offspring.

James Thuch Madhier fled South Sudan as a teenager, escaping the ravages of civil war and famine.

Next fall, the U of T undergrad and his social entrepreneurship team will be testing out their solar-powered crop irrigation system on 20 acres of land they've acquired in South Sudan.

Consumer goods companies often rely on life-cycle assessments (LCA) to figure out the potential consequences of how they design products and source ingredients. This kind of assessment, while sophisticated, often lacks detail about how the products affect natural resources such as land, water and biodiversity.

A team of researchers from Stanford University and the University of Minnesota, in a partnership called the Natural Capital Project, along with researchers from Unilever’s Safety and Environmental Assurance Centre, developed a new kind of assessment to integrate these impacts in a more detailed way. They call it Land Use Change Improved Life Cycle Assessment, or LUCI-LCA. It’s designed to help researchers or companies more accurately predict impacts of new designs and sourcing.

The mechanism behind oil synthesis within microalgae cells has been revealed by a Japanese research team. This discovery could contribute to the development of biofuels. The findings were published on April 4 in Scientific Reports.

Cover crops long have been touted for their ability to reduce erosion, fix atmospheric nitrogen, reduce nitrogen leaching and improve soil health, but they also may play an important role in mitigating the effects of climate change on agriculture, according to a Penn State researcher.

It’s a fish-eat-fish world out in the ocean, and prey species usually fear the predators that would make them into a tasty snack.

In the Microbial Sciences Building at the University of Wisconsin–Madison, the incredibly efficient eating habits of a fungus-cultivating termite are surprising even to those well acquainted with the insect’s natural gift for turning wood to dust. - See more at: http://news.wisc.edu/termite-gut-holds-a-secret-to-breaking-down-plant-biomass/#sthash.wNKkjWOk.dpuf

Most if not all the fires in this image taken by Suomi NPP satellite's VIIRS (Visible Infrared Imaging Radiometer Suite) instrument on April 11, 2017 are controlled fires set by farmers to manage land.  Farmers in Kansas as allowed to burn grass every year to produce better grass for cattle.  The grass burning typically occurs between March and mid-April on a yearly basis.

Decades of overpumping groundwater have irreversibly altered layers of clay beneath California's Central Valley, permanently reducing the aquifer's ability to store water, finds a new satellite remote sensing study by scientists at Stanford University, Stanford, California; and NASA's Jet Propulsion Laboratory in Pasadena, California.
