Agricultural heritage in disintegration: Trends of agropastoral transhumance on the southeast Tibetan Plateau.

This paper examines agropastoral transhumance in 12 sampled villages on the southeast Tibetan Plateau. By analysing trends in this indigenous livelihood system and examining causes and potential consequences, we conclude that Tibetan agropastoral transhumance is a fragile system extremely vulnerable to external impacts. Within the context of China's rapid development and globalisation, this agricultural heritage is changing rapidly, as is most saliently reflected in herd size and structure, movement patterns, relative economic importance of pastoral activities and the relations between pastoralism and crop cultivation. Immediate causes of changes are local changes in livestock management objectives, land uses and labour availability, which are driven by more fundamental changes of environmental, political, socioeconomic, technological and cultural profiles, from local to global scales. Changes in local livelihood systems can have multifaceted and profound political, socioeconomic, cultural and ecological consequences, in both constructive and destructive terms. Policy-makers and/or project designers must have a holistic perspective so as to integrate multiple objectives of promoting sustainable socioeconomic development, preserving biological and cultural diversities and maintaining the environmentally stable balance of human society, animal population and ecosystem that has existed in the area for centuries.
