Vulnerability assessment is an important step in developing adaptation strategies. For biogeographically vital and extremely heterogeneous regions like Himalaya, assessing vulnerability as an inherent characteristic becomes crucial. The present study assesses the inherent vulnerability (IV) for farming communities of Himachal Pradesh as a function of sensitivity and adaptive capacity using social and ecological indicators, group-decision methods, and Geographical Information System (GIS) tools. Data for 13,877 villages in three different biogeographical zones (Lower Himalaya (LH), Middle Himalaya (MH), Trans-Himalaya Tibetan Plateau (THTP)) was collected from secondary sources. Analytical Hierarchical Process (AHP) was applied to weigh the social and ecological indicators. Weighted indicators were finally aggregated to generate the final inherent vulnerability index (IVI). The IVI values for different biogeographical zones (LH 0.35 ± 0.13, MH 0.42 ± 0.14 and THTP 0.30 ± 0.17) reveal that geographical location of zones played a decisive role in distribution of IV. MH showed the highest vulnerability due to fragile inherent biophysical and socio-economic conditions. The findings of this study will aid in better resource management for farming communities to enhance the agriculture capabilities of vulnerable zones. The findings of this study also have inference for developing adaptation strategies for present stressors in the region.

评估印度喜马al尔邦不同生物地理区域内农业社区的固有脆弱性

脆弱性评估是制定适应策略的重要一步。对于像喜马拉雅山这样的生物地理至关重要的地区和极为异质的地区,将脆弱性评估为一种固有特征变得至关重要。本研究使用社会和生态指标,群体决策方法和地理信息系统(GIS)工具,评估了喜马al尔邦农业社区固有的脆弱性(IV),作为敏感性和适应能力的函数。从次要来源收集了三个不同生物地理区域(下喜马拉雅(LH),喜马拉雅中部(MH),喜马拉雅高原(THTP))的13877个村庄的数据。运用层次分析法(AHP)对社会和生态指标进行权衡。最后对加权指标进行汇总,以生成最终的固有漏洞指数(IVI)。不同生物地理区域的IVI值(LH 0.35±0.13,MH 0.42±0.14和THTP 0.30±0.17)显示区域的地理位置在IV的分布中起着决定性的作用。由于脆弱的固有生物物理和社会经济条件,MH显示出最高的脆弱性。这项研究的结果将有助于改善农业社区的资源管理,以增强脆弱地区的农业能力。这项研究的发现还可以为该地区目前的压力源制定适应策略。17)揭示区域的地理位置在IV的分配中起着决定性的作用。由于脆弱的固有生物物理和社会经济条件,MH显示出最高的脆弱性。这项研究的结果将有助于改善农业社区的资源管理,以增强脆弱地区的农业能力。这项研究的发现还可以为该地区目前的压力源制定适应策略。17)揭示区域的地理位置在IV的分配中起着决定性的作用。由于脆弱的固有生物物理和社会经济条件,MH显示出最高的脆弱性。这项研究的结果将有助于改善农业社区的资源管理,以增强脆弱地区的农业能力。这项研究的发现还可以为该地区目前的压力源制定适应策略。
