自然资源作为农村社区生计的资产发挥着关键作用。然而,这些资产在生计方面的好处往往被狭隘地理解为创收或减少脆弱性。我们认为,他们在减少贫穷和改变生计方面还可以发挥其他重要作用。在本文中,我们使用的两个民族社区在印度南部的一个村庄的案例研究,调查生计的森林生物多样性变化的反应,通过检查的自然资产的属性的变化所造成的入侵ofLantana camara和更广泛的社会经济变化。兰塔纳对森林的入侵导致了四种关键自然资产的属性和功能的变化:森林放牧、竹子编织、凤凰木扫帚和野山药。我们观察到,家庭和个人替代损失或减少的资产的重要功能的能力的差异影响他们适应资源可用性和属性变化的能力。通过分析不同用户群体的资产属性变化,可以对环境变化的社会影响进行分类。
Natural resources play key roles as assets in the livelihoods of rural communities. However, the benefits of these assets in livelihoods are frequently conceived narrowly as income generating or vulnerability reducing. We contend that they have other important roles to play in poverty reduction and livelihood change. In this paper we use a case study of two ethnic communities in a village in southern India to investigate livelihood responses to change in forest biodiversity through an examination of changes in attributes of natural assets resulting from the invasion ofLantana camaraand wider socio-economic change. The invasion of forest byLantanahas contributed to changes in the attributes and functions of four key natural assets: forest grazing, bamboo for basketry,Phoenix loureiefor brooms, and wild yams. We observe that differences in households’ and individuals’ ability to substitute important functions of lost or declining assets affect their ability to adapt to changes in resource availability and attributes. Analysing changes in asset attributes for different user groups allows the social effects of environmental change to be disaggregated.
