  • Indian Practices Could Mitigate Negative Impact of Livestock Rearing on Climate Change
    [Publicat la: 22/11/2017]
    A recent report from Oxford University indicts grazing livestock as a whole, without going into how certain such practices could actually change things for the better.
  • To address hunger effectively, first check the weather, says new study
    [Publicat la: 24/11/2017]
    Too little rain, or too much, is often a driver of poverty and hunger, leading to poor nutrition and food insecurity among vulnerable populations. According to a new study, rainfall patterns also provide clues on how to most effectively alleviate food insecurity.
  • France halts sales of two Dow pesticides over bee fears
    [Publicat la: 24/11/2017]
    A French court on Friday halted sales of two pesticides made by US chemicals giant Dow after an environmental group raised fears that the substances could be harmful to bees.
  • 'Lost' 99% of ocean microplastics to be identified with dye?
    [Publicat la: 24/11/2017]
    New research, led by Gabriel Erni-Cassola and Dr. Joseph A. Christie-Oleza from Warwick's School of Life Sciences, has established a pioneering way to detect the smaller fraction of microplastics - many as small as 20 micrometres (comparable to the width of a human hair or wool fibre) - using a fluorescent dye.
  • Climate change could increase volcano eruptions
    [Publicat la: 24/11/2017]
    A new study, led by the University of Leeds, has found that there was less volcanic activity in Iceland when glacier cover was more extensive and as the glaciers melted volcanic eruptions increased due to subsequent changes in surface pressure.
  • Natural Solutions to Climate Change
    [Publicat la: 24/11/2017]
    OXFORD - In response to climate change, land is key. Today, agriculture, forestry, and other land uses account for roughly a quarter of global greenhouse-gas emissions. But adopting sustainable land management strategies could provide more than one-third of the near-term emission reductions needed to keep warming well below the target - 2°C above pre-industrial levels - set by the Paris climate agreement.
  • Disrupting sensitive soils could make climate change worse, researchers find
    [Publicat la: 24/11/2017]
    Nearly a third of the carbon dioxide released into the atmosphere annually can be traced back to bacteria living in the soil, where they break down plant and animal matter for energy.
  • People must be aware of the threat of climate change - Holness
    [Publicat la: 24/11/2017]
    Prime Minister Andrew Holness says events such as the flooding in Montego Bay must be used as a platform to communicate with Jamaicans the great threat that we face from climate change.
  • Floods, Droughts, and India's Uncertain Climate Future
    [Publicat la: 24/11/2017]
    Legend has it that during the 90 days of monsoon in Bihar, one of the largest and most densely populated states in India, an overflowing river wouldn't dare touch the pole outside a rural house, where cattle would be tied. There were names for different levels of the water: water until the doorstep is termed baarh, water reaching the lower edge of the window is boh, cattle safely floating in the water is humma, water until the roof is saah, and water beyond the roof is pralay - best translated as "deluge."
  • When pictures tell stories of threat to planet
    [Publicat la: 24/11/2017]
    Sharjah: Despite facing days of frustration, bad luck and threat to their lives, wildlife photographers bring us the most perfect glimpses into a world that not many have a first-hand knowledge of. But what are mere pictures to us are, to wildlife photographers, stories of life itself, which is under threat for many species of wildlife.
  • Falling koala numbers not a crisis, says expert
    [Publicat la: 24/11/2017]
    Australia's cuddliest native animal is at the centre of fierce scientific dispute, with new research challenging conventional assumptions about koalas, their relationship with the bush and the wisdom of conservation campaigns designed to increase their numbers in the wild.
  • What if there is a price tag on nature?
    [Publicat la: 24/11/2017]
    If "natural capital" takes its course, the unaccounted value of nature-clean air, fresh water, wetlands, forests and many other "free goods from nature's bounty" that keep us alive-will have an economic value and most probably be accounted for. For example, wetlands would have an economic value for water cycling-they soak up surface water, filter it and slowly release it back to the surface-and flood control mechanisms, and forests for carbon sequestration.
  • Brilliant blue tarantula among potentially new species discovered in Guyana
    [Publicat la: 24/11/2017]
    While walking through the forests of Guyana's Potaro Plateau one night in 2014, herpetologist Andrew Snyder noticed a flash of bright cobalt blue peeking out of hole in a rotting tree stump. When Snyder took a closer look, he noticed that his flashlight had illuminated a small tarantula's blue legs. The tree stump had numerous small holes, and nearly every hole housed a similar blue tarantula.
  • Our disappearing biodiversity
    [Publicat la: 24/11/2017]
    The passenger pigeon, the woolly mammoth and the Tasmanian tiger - what do they all have in common? They are extinct. But how many animals have died out? And how many more will? Global Ideas takes a look.
  • Flies' disease-carrying potential may be greater than thought, researchers say
    [Publicat la: 24/11/2017]
    Flies can be more than pesky picnic crashers, they may be potent pathogen carriers, too, according to an international team of researchers.
  • Rolling back the tide of pesticide poison, corruption and looming mass extinction
    [Publicat la: 24/11/2017]
    An anthropogenic mass extinction is underway that will affect all life on the planet and humans will struggle to survive the phenomenon. So claims Dr Rosemary Mason in a paper (2015) in the Journal of Biological Physics and Chemistry.
  • Amazon tribe saves plant lore with 'healing forests' and encyclopedia
    [Publicat la: 24/11/2017]
    The seven indigenous Matsés elders were slowly meandering through the forest. They were explaining how different trees and plants are used for medicinal purposes, exchanging stories about how they had acquired their extraordinary knowledge and put it to good use. There were memories of an encounter with a jaguar and someone's father struck by some kind of pain in the eye - "not conjunctivitis!" - while claims were made for successfully treating women haemorrhaging, snake-bite, a swollen leg and constipation.
  • Is culture missing from conservation? Scientists take cues from indigenous peoples.
    [Publicat la: 24/11/2017]
    We typically think of conservation as removing humans from the ecosystem to return it to its 'natural' state. But the practices of many indigenous cultures offer a different way to view humanity's relationship with the natural world.
