Although there is an urban legend that the world will end this year based on a misinterpretation of the Mayan calendar, some researchers think a 40-year-old computer program that predicts a collapse of socioeconomic order and massive drop in human...
Forest gardening seems nuts to some people who love the simplicity and effectiveness of herbicides plus GE crops - but with genetic mutations now also spreading to weeds, farmers are in trouble. Not so the chemical companies though - they get a chance to sell more products including ones similar to Agent Orange.
Tennessee reaps a $638 million yearly benefit from its urban trees – and an $80 billion loss if they disappeared.
Through energy savings, air and water filtering and carbon storage, the urban trees of Tennessee account for more than $638 million in benefits, according to a report [PDF] conducted by the Forest Service of the U.S. Department of Agriculture and released earlier this year.
The biggest savings are attributed to carbon storage, which the authors of the report value at an estimated $350 million. Collectively, the state's urban trees store about 16.9 million tons, with each ton stored worth about $20.70 to the state every year. Air and water filtration is also one of the functional benefits of urban trees, and the report estimates the value of this work at $204 million per year. The trees are credited with removing 27,100 tons of pollutants each year, including ozone, particulate matter, and sulfur dioxide. And because of the shading they provide, these urban trees are credited with saving about $66 million in energy costs annually.
Economic growth with resilience to environmental threats will be central to the agenda of the UN Conference on Sustainable Development (Rio+20) in June this year, which aims to map out a pathway of sustainable development for the planet. The 'zero draft', the document that will form the basis of conference negotiations, states a resolve to fight hunger, eradicate poverty and work towards just and economically stable societies. Food security is critical to this mission. The threats are numerous: repeated food price spikes; shortages of good-quality land and water; rising energy and fertiliser prices; and the consequences of climate change. Already, somewhere between 900 million and a billion people are chronically hungry, and by 2050 agriculture will have to cope with these threats while feeding a growing population with changing dietary demands. This will require doubling food production, especially if we are to build up reserves for climatic extremes. To do this requires sustainable intensification — getting more from less — on a durable basis.
Perennial vegetable gardens build soil the way nature intended—by allowing the plants to add more and more organic matter without tillage, and letting the worms do the work of mixing it all together. Perennials provide ecosystem benefits.
I've just returned from Ethiopia, and was making many conclusions related to this new blog! More will follow on the dreadful circle of firewood collection, rampant animals, more and more goats ... but meanwhile:
"Regreening initiatives are striving to combat or even reverse land degradation in the arid Sahelian region of Africa. This tactic is reaching significant scale, with benefits not only to the environment, but also for agricultural production and the livelihoods of rural people. Tony Rinaudo, World Vision’s natural resource management advisor in Australia, and wife Liz (also with World Vision) discuss one such project in Humbo, Ethiopia. They are travelling in East Africa for three months (March-May) to stimulate the regeneration of forests and farmland using Farmer Managed Natural Regeneration.
Ethiopia – once a land of beautiful forests is now largely characterised by denuded mountains, cavernous eroded gullies and richly soiled fields traversed by smaller channels. From the top of many hills, the landscape appears deeply scarred.
Humbo in southern Ethiopia is an area which has been racked by famine, which resulted in communities receiving food aid year after year."
Loss of biodiversity appears to impact ecosystems as much as climate change, pollution and other major forms of environmental stress, according to a new study. The study is the first comprehensive effort to directly compare the impacts of biological diversity loss to the anticipated effects of a host of other human-caused environmental changes.
“Diversity of diet, founded on diverse farming systems, delivers better nutrition and greater health, with additional benefits for human productivity and livelihoods,” said Emile Frison, Director General of Bioversity International at the launch of...
The New York Botanical Garden; the Missouri Botanical Garden; The Royal Botanic Gardens, Kew; and the Royal Botanic Garden Edinburgh have announced plans to develop the World Flora - the first modern, online catalog of the world's plants - by the year 2020. This massive undertaking will include the compilation of information on up to 400,000 plant species worldwide. It will also achieve a primary target of the Global Strategy for Plant Conservation, an ambitious effort first adopted by the United Nations' Convention on Biological Diversity in 2002, to halt the continuing loss of plant biodiversity around the globe.
