Pastoralism provides crucial services to humanity, can support green economy transition — Last modified May 22, 2015 08:20
Pastoralism-extensive livestock production in the rangelands-provides enormous benefits to humanity and should be supported as a key element of the global transition to a green economy, according to a new report released today by the United Nations Environment Programme (UNEP) and the International Union for Conservation of Nature (IUCN).
Trees photosynthesized more slowly during 2010 Amazon drought — Last modified May 20, 2015 08:47
As climate changes the Amazon region could see more frequent and longer periods of drought. Now an international team has come up with the first direct evidence of changing rates of carbon absorption by rainforest trees experiencing reduced rainfall, finding that photosynthesis slowed by around 10% for six months.
Predicting plant responses to drought — Last modified May 18, 2015 09:19
A new U.S. Geological Survey study shows how plants' vulnerability to drought varies across the landscape; factors such as plant structure and soil type where the plant is growing can either make them more vulnerable or protect them from declines.
‘Spiderweb’ of land deals could propagate crisis — Last modified May 18, 2015 09:15
Throughout the 20th Century, trading commodities between countries was common. But at the start of the 21st Century an increasing number of nations also began to buy and lease land. Sparked off by rising oil prices and concerns over food security, land acquisition has surged over the last decade. Now researchers from Lund University in Sweden have used network analysis to study land deals between countries, and assess the dependencies that this new form of trade is creating.
Global Soil Week Considers Role of Soil Carbon in Uniting Post-2015 Land, Soil Science and Climate Agendas — Last modified April 30, 2015 13:29
A focus on soil carbon sequestration could offer a common entry point for improved collaboration among science-policy bodies dealing with different aspects of land management, soil science and climate change.
Fukushima Cotton's Appeal — Last modified April 08, 2015 09:54
The Fukushima Organic Cotton Project started its third year of cultivation in its cotton fields, and like previous years, many volunteers are coming to help with the work each weekend. There are many repeat volunteers, some of whom are enjoying reunions with one another in the cotton fields.
Are legumes better than fertiliser in developing countries? — Last modified March 02, 2015 07:53
Many developing parts of the world – including China, India and Pakistan, as well as much of Central America and North Africa – can’t expect greater agricultural yields from increased nitrogen fertilization without a "disproportionate" cost to the environment. That’s the conclusion of researchers in France and Italy, who say that nitrogen fixation by legumes can be much more efficient on large scales.

Wildfires boost Australia’s carbon sink — Last modified January 12, 2015 09:04
As climate change causes wildfires to become more prevalent, you’d expect a net increase in atmospheric carbon. But that’s not the result from a computer model of Australian vegetation, which suggests that extended burnt areas will actually enlarge the country’s carbon sink. The results – which are due partly to a phenomenon called carbon dioxide fertilization, and partly to the ability of certain trees to recover quickly after forest fires – are likely to apply to other savannah and semi-arid regions of the world, the study’s authors believe.
