Effect of afforestation on soil fungal community structure is greater than spatial distance
Afforestation is an important strategy to enhance terrestrial carbon sink. It alters regional landscapes and affects microbial processes in soil ecosystems. In particular, soil fungi, which play an important role in carbon and nitrogen cycling, could be greatly affected. However, at a watershed scale, the changes of soil fungal communities under afforestation could not only be influenced by host ...

Management of rice paddy fields affects greenhouse gas emissions
How rice paddy fields are managed significantly influences the release of greenhouse gases (GHGs), a recent study concludes. Permanently flooded soils release more methane than soils that are flooded and then dried between production periods, for example. In general, the researchers recommend growing other crops in dried soil between production cycles, as well as limiting nitrogen fertilisers, to ...

Typhoon-stricken farmers receive first emergency seeds
One month after Typhoon Haiyan struck a devastating blow to the Philippines, farmers who lost essential crops and supplies are receiving the first wave of emergency seeds, restoring hope for a productive planting season and much-needed food for the coming year. FAO and the Philippines' Department of Agriculture (DA) have begun delivering the first rice and corn seed allocations to rural ...

Cows’ diets get environmental boost
It is a tiny molecule with a mouthful of a name, 3-nitrooxypropanol, but European scientists say it could make all the difference. It could convert a cow or a sheep from a monstrous methane-producing machine into something a little more environmentally friendly. In doing so, it could increase the energy that a ruminant could employ in making milk or meat. And, according to a new research ...

Ecosystem-based farming comes of age
A new FAO book out today takes a close look at how the world's major cereals maize, rice and wheat - which together account for an estimated 42.5 percent of human calories and 37 percent of our protein - can be grown in ways that respect and even leverage natural ecosystems. Drawing on case studies from around the planet, the new book illustrates how the "Save and Grow" approach to agriculture ...

Scientists take on greenhouse gas challenge
Swiss scientists have found a way to turn the potent greenhouse gas methane into the fuel methanol – with help from water and a simple catalyst. Meanwhile, US researchers have tested a way to convert methane into biofuels, specialised chemicals or even cattle feed with help from one microbe from rice fields and another from a Siberian lake. And in Norway, engineers are testing something ...

Farming needs lead role in GHG cuts
The world’s farmers and food producers must do more – perhaps five times as much – to reduce the greenhouse gas (GHG) emissions that threaten catastrophic global climate change, according to new research. Right now, scientists calculate that the options available to meet the recent Paris Agreement to limit global warming to a maximum of 2°C above historic levels would ...
