“Bread and Freedom” said the insurgents’ many posters in Cairo and Tunis. The hunger of millions of people and rising food prices were undoubtedly among the triggers of both revolutions.

:: Extension of energy production from biomass requires careful consideration

Energy production from plants could provide up to twenty percent of the world's energy demand in 2050, half of it from biomass plantations alone – but only at the price of a substantial expansion of land used for cultivation, to the expense of nature. This is the finding of a study carried out by the Potsdam Institute for Climate Impact Research (PIK) “which for the first time determines the potential and the risks of energy production from biomass plantations in a complex biogeochemical computer simulation,“ lead author Tim Beringer says. Human land use could increase by ten to thirty percent, depending on the scenario, and irrigation water demand could double.

:: Talk at Cancun is of 2 degrees Celsius – even 1.5 degrees would have effects lasting centuries

Even global warming of just 1.5 degrees Celsius would have consequences for centuries. The oceans store elevated temperatures for a longer time than was previously thought. This is due to a change in ocean-atmosphere heat exchange, scientists of the Potsdam Institute for Climate Impact Research discovered. Heat in lower oceanic layers is trapped by a cooling of upper layers, says a study which is about to be published in the journal Earth System Dynamics.

:: New World Bank Report Sees Growing Global Demand for Farmland

A new World Bank report says volatility in food prices has been a key factor behind a rising tide of large scale farmland purchases in the developing world, which can pose social and environment risks, if not well managed. The report, Rising Global Interest in Farmland, calls on developing countries to recognize and respect resource rights of their people, warning that countries with poor records of formally recognized land tenure attract strong investor interest – which raises real concerns about the ability to protect vulnerable people from losing their land.

:: Where on earth is biodiversity?

New biodiversity tool to encourage conservation-driven decision making. Mount Kenya, the second-highest peak in Africa, is renowned for its rich tableau of animal and plant life. But according to a new United Nations Environment Programme (UNEP) database, animal and plant species living on the 5,199 meter peak are globally threatened.
