Land Cover Change in Agroforestry: Shade Coffee in El Salvador
研究了1990年代萨尔瓦多荫蔽咖啡种植区的土地清理情况，发现市场邻近性与清理的关系与天然林相反，且结果取决于种植区特征和清理后的主导土地利用。
Little is known about land cover change in agroforestry systems, which often supply valuable ecological services. We use a spatial regression model to analyze clearing in El Salvador’s shade coffee–growing regions during the 1990s. Our findings buttress previous research suggesting the relationship between proximity to markets and clearing in agroforestry systems is the opposite of that in natural forests. But this result, and several others, depends critically on the characteristics of the growing area, particularly the dominant cleared land use. These findings imply that policies aimed at retaining agroforestry need to be carefully targeted and tailored. <i></i>
