Environmental Income and Rural Livelihoods: A Global-Comparative Analysis
基于24个发展中国家约8000户家庭的数据，分析了环境收入占家庭总收入的比例（28%），发现低收入家庭更依赖非木材林产品，但高收入家庭的环境收入绝对值更高。
This paper presents results from a comparative analysis of environmental income from approximately 8000 households in 24 developing countries collected by research partners in CIFOR's Poverty Environment Network (PEN). Environmental income accounts for 28% of total household income, 77% of which comes from natural forests. Environmental income shares are higher for low-income households, but differences across income quintiles are less pronounced than previously thought. The poor rely more heavily on subsistence products such as wood fuels and wild foods, and on products harvested from natural areas other than forests. In absolute terms environmental income is approximately five times higher in the highest income quintile, compared to the two lowest quintiles.
