Forest Degradation and Economic Growth in Nepal, 2003–2010
研究2003-2010年尼泊尔经济增长与家庭薪柴采集及森林状况的关系,发现森林状况稳定,家庭薪柴采集减少,替代能源使用增加,结构性变化抵消了增长的环境影响。
We investigate the relation between economic growth, household firewood collection, and forest conditions in Nepal between 2003 and 2010. Comovements in these are examined at the household and village levels, combining satellite imagery and household (Nepal Living Standard Measurement Survey) data. Projections of the impact of economic growth based on Engel curves turn out to be highly inaccurate: forest conditions remained stable despite considerable growth in household consumption and income. Firewood collections at the village level remained stable, as effects of demographic growth were offset by substantial reductions in per household collections. Households substituted firewood by alternative energy sources, particularly when livestock and farm-based occupations declined in importance. Engel curve specifications which include household productive assets (a proxy for occupational patterns) provide more accurate predictions. Hence structural changes accompanying economic growth play an important role in offsetting adverse environmental consequences of growth.
