Limited nutrients may keep plants from growing as fast as scientists thought
April 21, 2015 09:00 AM - Tim Wogan, Science/AAAS
Plants are one of the last bulwarks against climate change. They feed on carbon dioxide, growing faster and absorbing more of the greenhouse gas as humans produce it. But a new study finds that limited nutrients may keep plants from growing as fast as scientists thought, leading to more global warming than some climate models had predicted by 2100.
Think Different: Apple and conservation
April 17, 2015 07:14 AM - Andrew Burger, Triple Pundit
Marking a precedent-setting conservation partnership, Apple and the Conservation Fund will purchase two large areas of working forest, the organizations announced on Thursday. The move is expected to conserve “more than 36,000 acres of working forestland in Maine and North Carolina, ensuring these forests stay forests and any timber on the land is harvested sustainably,” the partners said in a joint announcement.
This initial purchase of U.S. working forestland marks “the beginning of a worldwide effort, one that represents a new approach as it reassesses its impact on the world’s paper supply chain,” Lisa P. Jackson, Apple’s vice president of environmental initiatives, and Larry Selzer, president and CEO of the Conservation Fund, wrote in a Medium op-ed. Prior to joining Apple, Jackson led the U.S. EPA as President Barack Obama’s EPA Administrator from 2009 to 2013.
How California distributes scarce water
April 15, 2015 08:09 AM - Dan Charles, NPR
The state of California is asking a basic question right now that people often fight over: What's a fair way to divide up something that's scarce and valuable? That "something," in this case, is water.
There's a lot at stake, including your very own nuts, fruit and vegetables, because most of the water that's up for grabs in California goes to farmers. This year, some farmers will get water, and others will not, simply based on when their land was first irrigated.
Consider, for instance, the case of Cannon Michael. He grows tomatoes and melons in California's Central Valley. And despite the drought, he'll still grow them this year.
The impact levees have on groundwater recharge
April 12, 2015 08:54 AM - Kat Kerlin, UC Davis News Service via ECOreport
Strange as it sounds, flood control can be part of the solution to managing California’s droughts. University of California scientists have shown that making more room for floodwaters can improve the state’s groundwater supplies and fisheries.
Removing some levees or rebuilding aging ones some distance away from riverbanks can appreciably replenish aquifers during wet years, providing some relief during droughts.
Record low snowpacks in Southwest is bad news for water supplies
April 11, 2015 07:57 AM - Roy L Hales, the ECOreport
Nine states report record low snowpacks. A report from the US Department of Agriculture states, “the largest snowpack deficits are in record territory for many basins,especially in the Cascades and Sierra Nevada where single – digit percent of normal conditions prevail. Very low snowpacks are reported in most of Washington, all of Oregon, Nevada, California, parts of Arizona, much of Idaho, parts of New Mexico, three basins in Wyoming, one basin in Montana, and most of Utah.” This region is undergoing the warmest winter temperatures since record keeping began in 1895.
How can we improve plant growth?
April 10, 2015 08:36 AM - Edd Gent, SciDevNet
Supercomputers and genetic engineering could help boost crops’ ability to convert sunlight into energy and tackle looming food shortages, according to a team of researchers. Photosynthesis is far from its theoretical maximum efficiency, say the authors of a paper in Cell, published on 26 March. They say that supercomputing advances could allow scientists to model every stage in the process and identify bottlenecks in improving plant growth.
Neonicotinoids Responsible for Pollinator Declines Worldwide
April 9, 2015 02:46 PM - Jonathan Latham, The Ecologist
Monarch caterpillars are vulnerable to neonicotinoid toxicity at concentrations as low as 1 part per billion, writes Jonathan Latham, and that makes them vulnerable to residues from commercial crops - and even more so from horticultural use in plant nurseries!
EPA Moves to Restrict Bee-killing Pesticides
April 7, 2015 01:45 PM - Alicia Graef, Care2
The Environmental Protection Agency (EPA) has finally taken some action to restrict the use of pesticides that are believed to be causing serious declines in pollinators, but environmentalists are arguing the agency still needs to do more.
Why does water rationing in California exclude fracking and agribusiness?
April 6, 2015 07:31 AM - Evan Blake, The Ecologist
California has responded to the drought by rationing water, with $500 fines for domestic 'water wasters', writes Evan Blake. But agribusiness and water-intensive industries like fracking remain untouched by the restrictions, even though they consume over 90% of the state's water.
There are immense water efficiencies to be gained, but any rational reorganization is blocked by the US financial oligarchy, which, controlling the entire political system, will not abide any impingement on its profits.
The unprecedented drought gripping California has deepened for the fourth consecutive year, having already set new records for the lowest annual precipitation levels on record.
Plowing prairies for grains
April 2, 2015 09:08 AM - University of Wisconsin-Madison via EurekAlert!
Clearing grasslands to make way for biofuels may seem counterproductive, but University of Wisconsin-Madison researchers show in a study today (April 2, 2015) that crops, including the corn and soy commonly used for biofuels, expanded onto 7 million acres of new land in the U.S. over a recent four-year period, replacing millions of acres of grasslands.
