Population Pressure, Land Tenure, and Tree Resource Management in Uganda
利用乌干达东部64个教区的航拍照片和调查数据，研究发现习惯土地制度、人口压力大和市场准入差是林地转为农田的主因，而私有化促进农林复合经营，有助于维持树木数量。
This study uses aerial photographs and survey data from sixty four parishes in east-central Uganda to identify the factors affecting conversion of woodlands and traditional grazing areas to agriculture. Regression analysis shows that customary land tenure institutions, greater population pressure and poor access to markets are significant causes of land conversion to agriculture, and hence to loss of trees. Private ownership of converted land promotes greater integration of trees and crops and leads to the highest density of trees on agricultural land. Given that continuing population growth will lead to further land conversion to agriculture, the best prospect for maintaining or increasing tree populations lies with agroforestry on cultivated land.
