Causes of California drought linked to climate change, Stanford scientists say
The atmospheric conditions associated with the unprecedented drought currently afflicting California are "very likely" linked to human-caused climate change, Stanford scientists write in a new research paper. In a new study, a team led by Stanford climate scientist Noah Diffenbaugh used a novel combination of computer simulations and statistical techniques to show that a persistent region of high atmospheric pressure hovering over the Pacific Ocean that diverted storms away from California was much more likely to form in the presence of modern greenhouse gas concentrations. >> Read the Full Article
The important role that agroecological farming can play to feed the world
Governments must shift subsidies and research funding from agro-industrial monoculture to small farmers using 'agroecological' methods, according to the UN's Special Rapporteur on the Right to Food. And as Nafeez Ahmed notes, her call coincides with a new agroecology initiative within the UN's Food and Agriculture Organisation. This is critical for future agricultural policies. Currently, most subsidies go to large agribusiness. This must change. Governments must support small farmers. Modern industrial agricultural methods can no longer feed the world, due to the impacts of overlapping environmental and ecological crises linked to land, water and resource availability. >> Read the Full Article
If Hops aid cognitive function in mice, maybe beer will do it in humans
Xanthohumol, a type of flavonoid found in hops and beer, has been shown in a new study to improve cognitive function in young mice, but not in older animals. The research was just published in Behavioral Brain Research by scientists from the Linus Pauling Institute and College of Veterinary Medicine at Oregon State University. Itâ€™s another step toward understanding, and ultimately reducing the degradation of memory that happens with age in many mammalian species, including humans. >> Read the Full Article
The Future of Vertical Farming
From big company agricultural farming, to communal farming or even personal agronomy, the business of growing crops for an expanding global population will be crucial in the near future. The two most important resources needed to run these farms are one, water, and two, land. But these resources often come at a premium, especially with growing populations and increased food demand. Farmers and researchers have already started leaning towards genetic engineering and industrial processing to help with their crop yields, but a new solution in agribusiness is emerging. Vertical farming. >> Read the Full Article
California Drought: Why Farmers Must Adapt
The entire state of California is in a drought. A big part of the state, including the fertile Central Valley, is experiencing the worst category of drought, exceptional. California supplies much of the fruits, vegetables and nuts the nation eats. In inland areas such as the Central Valley, as well as the combined Sacramento and San Joaquin valleys, agriculture truly rules. >> Read the Full Article
Illegal land clearing for commercial agriculture responsible for half of tropical deforestation
A comprehensive new analysis released today says that nearly half (49%) of all recent tropical deforestation is the result of illegal clearing for commercial agriculture. The study also finds that the majority of this illegal destruction was driven by overseas demand for agricultural commodities including palm oil, beef, soy, and wood products. In addition to devastating impacts on forest-dependent people and biodiversity, the illegal conversion of tropical forests for commercial agriculture is estimated to produce 1.47 gigatonnes of carbon each yearâ€”equivalent to 25% of the EU's annual fossil fuel-based emissions. >> Read the Full Article
How can we make lawns more environmentally friendly?
Many homeowners strive to have the picture-perfect green lawn. But how can that be achieved in an environment where water in parts of the country is becoming scarce and the use of pesticides and fertilizer is being discouraged? Researchers from two Big Ten universities hope that they will be able to find an answer. Scientists from Rutgers University and the University of Minnesota, both members of the Committee on Institutional Cooperation â€“ an academic consortium of Big Ten universities â€“ will be working together over the next five years to develop an environmentally friendly grass that is more resistant to disease and drought and a better economical choice for homeowners. >> Read the Full Article
Ozone pollution in India kills crops that could feed starving population
In one year, India's ozone pollution damaged millions of tons of the country's major crops, causing losses of more than a billion dollars and destroying enough food to feed tens of millions of people living below the poverty line. These are findings of a new study that looked at the agricultural effects in 2005 of high concentrations of ground-level ozone, a plant-damaging pollutant formed by emissions from vehicles, cooking stoves and other sources. Able to acquire accurate crop production data for 2005, the study's authors chose it as a year representative of the effects of ozone damage over the first decade of the 21st century. >> Read the Full Article
California FINALLY gets serious about protecting its groundwater
As California suffers through the third year of a record-breaking drought, state lawmakers agreed today to require more sweeping oversight of the stateâ€™s groundwater resources. California legislators approved Senate Bill 1168 and Assembly Bill 1739, which together call for stricter management of groundwater supplies by local agencies while giving the state the ability to step in when necessary. Up until now, California was the only state in the nation that did not comprehensively monitor or regulate groundwater. >> Read the Full Article
How Farm Pests Can Threaten Food Security
Agricultural pests - viruses, bacteria, fungi, blights, mildews, rusts, beetles, nematodes, flies, mites, spiders and caterpillars - are spreading thanks to trade, travel and global warming, writes Tim Radford. The world faces a dire future of increased crop losses and growing insecurity. Coming soon to a farm near you: just about every possible type of pest that could take advantage of the ripening harvest in the nearby fields. >> Read the Full Article
