The 20 best places to tackle U.S. farm nitrogen pollution

A pioneering study of U.S nitrogen use in agriculture has identified 20 places across the country where farmers, government, and citizens should target nitrogen reduction efforts.

The 20 nitrogen “hotspots of opportunity”–which appear on a striking map–represent a whopping 63% of the total surplus nitrogen balance in U.S. croplands, but only 24% of U.S. cropland area.

Nitrogen inputs are so high in these areas that farmers can most likely reduce nitrogen use without hurting crop yields.

Nuclear War Could Trigger Big El Niño and Decrease Seafood

A nuclear war could trigger an unprecedented El Niño-like warming episode in the equatorial Pacific Ocean, slashing algal populations by 40 percent and likely lowering the fish catch, according to a Rutgers-led study. The research, published in the journal Communications Earth & Environment, shows that turning to the oceans for food if land-based farming fails after a nuclear war is unlikely to be a successful strategy – at least in the equatorial Pacific.

Marine Fisheries Will Not Offset Farm Losses after Nuclear War

After a nuclear war, wild-catch marine fisheries will not offset the loss of food grown on land, especially if widespread overfishing continues, according to a Rutgers co-authored study. But effective pre-war fisheries management would greatly boost the oceans’ potential contribution of protein and nutrients during a global food emergency, according to the study in the journal Proceedings of the National Academy of Sciences. The study for the first time explored the effects of nuclear war on wild-catch marine fisheries.

Most Nations Failing to Protect Nature in COVID-19 Pandemic Recovery Plans

The COVID-19 pandemic provides an opportunity to reset the global economy and reverse decades of ecosystem and species losses, but most countries are failing to invest in nature-related economic reforms or investments, according to a Rutgers-led paper.

Rutgers Experts Can Discuss Invasive Spotted Lanternfly Spread in N.J.

New Brunswick, N.J. (Oct. 1, 2020) – Rutgers University–New Brunswick Professor George C. Hamilton and Associate Professor Anne L. Nielsen can discuss the spread of and threat posed by the invasive spotted lanternfly, a destructive pest, in New Jersey. “Their…

Researchers Use Satellite Imaging to Map Groundwater Use in California’s Central Valley

Researchers at the University of California San Diego report in a new study a way to improve groundwater monitoring by using a remote sensing technology (known as InSAR), in conjunction with climate and land cover data, to bridge gaps in the understanding of sustainable groundwater in California’s San Joaquin Valley.

Rutgers-Led Project Will Buy 76,000 Oysters From Farmers Struggling During COVID-19 Pandemic

New Brunswick, N.J. (Sept. 10, 2020) – A Rutgers-led project will buy 76,000 oysters from New Jersey oyster farmers who are struggling to sell the shellfish following the shutdown of restaurants and indoor dining as a result of the COVID-19…

New method to combat damage, help revive NY berry industry

Greg Loeb has been experimenting with a thin mesh covering, called exclusion netting, around berry crops as a means to prevent spotted wing drosophila (SWD) infestation. The efficacy of the netting is documented in a paper, “Factors Affecting the Implementation of Exclusion Netting to Control Drosophila Suzukii on Primocane Raspberry,” published in the journal Crop Protection.

Decline of Bees, Other Pollinators Threatens U.S. Crop Yields

Crop yields for apples, cherries and blueberries across the United States are being reduced by a lack of pollinators, according to Rutgers-led research, the most comprehensive study of its kind to date. Most of the world’s crops depend on honeybees and wild bees for pollination, so declines in both managed and wild bee populations raise concerns about food security, notes the study in the journal Proceedings of the Royal Society B: Biological Sciences.
