HINDAS第5回研究集会(HINDAS第1回国際ワークショップ) 報告

  題目:Environmental Changes and their Natural and Socio-economic Impacts in Himalaya

<要 旨>
Himalaya being tectonically alive, ecologically fragile, economically underdeveloped, socially marginalized and the most densely populated mountain is highly vulnerable to impacts of global environmental changes. The nature of terrain imposes severe limitations on scale of productive activities as well as on efficiency of infrastructural facilities. As a result, subsistence agriculture constitutes main source of rural livelihood for more than 75% population even though the availability of arable land is severely limited and agricultural productivity is low. During recent years, variety of changes have emerged in traditional resource use structure in Himalaya, mainly in response to population increase, globalizing economy, rapid urban growth and resultant increased demand and exploitation of natural resources. Moreover, changing climatic conditions have already stressed Himalayan ecosystem through higher mean annual temperatures and melting of glaciers, altered precipitation patterns and hydrological disruptions, and more frequent and extreme weather events. These changes are adversely affecting ecosystem services, particularly, water, forests and biodiversity, and consequently increasing vulnerability of large population particularly poor and marginalized sections to water, livelihood, food, health and social insecurity. Proposed talk will bring into focus the major drivers of environmental changes in Himalaya and present an overview of their impacts on nature, economy and society.

 本集会は、日本学術振興会の外国人研究者招へい事業(短期)により招いたP. C. ティワリ教授による報告・ワークショップである。広島大学拠点は同州における経済発展の実態把握についての研究を進めているが、本報告はそうした経済発展に伴う環境および社会への影響を軸にした報告が展開され、質疑ではパンチャーヤトといった地域社会組織の実態、変化や産業発展の地域的影響といった点に質問が多く寄せられた。広島大学拠点における山岳地域の経済発展に関する研究の推進において、こうした議論を重ねることが出来たのは大変有意義であった。(宇根義己)
