Old-growth forests important carbon sinks, says study

The Commission has rejected the notion that farmers should implement river basin management schemes in exchange for agricultural subsidies, despite increasing fears over water shortages and droughts.

The international group of scientists' findings indicate that old-growth forests in the northern hemisphere account for at least 10% of global net uptake of carbon dioxide. This contrasts with the commonly accepted view that these forests are carbon neutral, a hypothesis based mainly on a single study from the 1960s.

The new research builds on 519 plot studies and shows that carbon accumulation continues in forests that are centuries old. Nevertheless, the Kyoto Protocol does not call for forests to be left intact, instead demanding changes to the carbon stock by afforestation, reforestation and deforestation.

Rare rhinos endangered by loss of habitat

South Asia's endangered Great One-horned Rhinoceros is being driven out of its natural habitat in search of food into the hands of illegal poachers, experts said on Thursday.

A meeting of the Asian Rhino Specialist Group in Nepal said that the massive animal's feeding grounds were being invaded by "exotic species" of weeds and wild plants and the rhino could soon run out of natural fodder.

"Grassland is being invaded by weeds and other unwanted plants that are not suitable for rhinos," Bibhab Kumar Talukdar, co-chairman of the group said from the Chitwan National Park, home to 408 rhinos.

"We have to concentrate on how best to control the weeds and for this we have to intensify research."

The endangered animal, whose numbers have been rising in Nepal and India, is found mostly in the northeastern Indian state of Assam, and in southwestern Nepal.
