论文摘要
将种群分为群体间较高但较低的组内，异质性可用于增强许多社会经济政策干预的有效性；然而，它在促进清洁烹饪方面几乎没有受到关注。在这里，我们使用Permanova（一种基于距离的多元分析）来确定捕获烹饪燃料时捕获最高组间异质性的因素。将这种方法应用于来自尼泊尔的747,137户家庭的地震后数据，我们发现种族解释了燃料选择变化的39.12％，其次是收入（26.30％），教育（12.62％）和位置（4.05％）。这一发现表明，作为政策干预的基础，种族而不是收入或其他因素可能更有效地促进清洁烹饪。我们还发现，在尼泊尔的种族中，最边缘化的chepang/thami社区表现出最低的内部内部多样性（香农指数= 0.101），而纽瓦尔人则表现出最高的（0.667）。有关燃料选择中种族多样性的信息可能对减少清洁烹饪中种族差距的重要政策影响。
Segmenting population into subgroups with higher intergroup, but lower intragroup, heterogeneity can be useful in enhancing the effectiveness of many socio-economic policy interventions; yet it has received little attention in promoting clean cooking. Here, we use PERMANOVA, a distance-based multivariate analysis, to identify the factor that captures the highest intergroup heterogeneity in the choice of cooking fuels. Applying this approach to the post-earthquake data on 747,137 households from Nepal, we find that ethnicity explains 39.12% of variation in fuel choice, followed by income (26.30%), education (12.62%), and location (4.05%). This finding indicates that ethnicity, rather than income or other factors, as a basis of policy interventions may be more effective in promoting clean cooking. We also find that, among the ethnic groups in Nepal, the most marginalized Chepang/Thami community exhibits the lowest intragroup diversity (Shannon index = 0.101) while Newars the highest (0.667). This information on intra-ethnic diversity in fuel choice can have important policy implications for reducing ethnic gap in clean cooking.
