Climate change presents significant risks to marginalized communities, particularly in tribal groups like the Bhil and Bhilala communities of Madhya Pradesh, India. Limited empirical studies have focused on the effects of climate change on tribes in India. This study aims to assess climate change risk and vulnerability among tribal communities, employing the modified Mann-Kendall (MMK) test to identify climate trends, a risk assessment framework based on the Intergovernmental panel on climate change sixth assessment report (IPCC-AR6), and multiple linear regression (MLR). The MMK test indicates an increasing trend in rainfall (MMK = 1.099) and temperature. However, household perceptions reveal a high awareness of climatic changes, with 97% of respondents reporting irregularity in rainfall and 98% documenting increased summer hot days. The risk assessment shows that Bhil households face higher risk (0.107) than Bhilala households (0.068), which is determined by higher exposure and sensitivity. MLR results further emphasize that 12 of 23 indicators significantly affect risk assessment (R-squared = 0.698), with climatic events (β = 0.015), housing structure (β = 0.07), and food security being key contributors. The findings indicate that long-term climate trends are already affecting tribal livelihoods. It calls for targeted adaptation strategies, incorporating enhanced infrastructure, crop diversification, and better access to climate information and government schemes.
气候变化给边缘化社区带来了重大风险,尤其是在印度中央邦的比尔和比拉拉等部落群体中。有限的实证研究聚焦于气候变化对印度部落的影响。本研究旨在评估部落社区的气候变化风险和脆弱性,采用修正的曼-肯德尔(MMK)检验来识别气候趋势,基于政府间气候变化专门委员会第六次评估报告(IPCC-AR6)的风险评估框架,以及多元线性回归(MLR)。MMK检验表明降雨量(MMK = 1.099)和温度呈上升趋势。然而,家庭认知显示对气候变化的高度认知,97%的受访者报告降雨不规律,98%的受访者记录夏季炎热天数增加。风险评估显示,比尔家庭面临的风险(0.107)高于比拉拉家庭(0.068),这是由更高的暴露度和敏感度决定的。MLR结果进一步强调,23项指标中有12项对风险评估有显著影响(决定系数 = 0.698),气候事件(β = 0.015)、住房结构(β = 0.07)和粮食安全是关键因素。研究结果表明,长期气候趋势已经在影响部落生计。这需要有针对性的适应策略,包括加强基础设施建设、作物多样化,以及更好地获取气候信息和政府计划。
