The booklet Mountain Biodiversity and Climate Change was developed from the contributions made at the International Mountain Biodiversity Conference in November 2008 in Kathmandu, Nepal, which brought together representatives from the eight countries of the Hindu Kush-Himalayan region with representatives of global programmes with experience related to data collection and biodiversity conservation. It introduces a selection of the ideas presented and discussed, in the form of answers to questions that we hear people asking and in a richly illustrated format.
