摘要

作为利比里亚顶极植被的热带雨林需要现代和优先的科学管理办法。目前的评估表明,利比里亚的森林正在减少,但利比里亚仍然拥有世界上最大的原始森林遗迹之一。巴西、南美洲的亚马逊地区和中非的刚果盆地拥有更大的森林,但利比里亚的森林面积很大,是农业和林业的真正经济资源。对木材、非木材林产品、采矿和农产品的需求的反应是砍伐森林和清理土地,这两者都对森林和农业用地造成负面影响。清理土地,包括完全移除高大健壮的树木,通常是必要的。因此,小农主要关注的是砍伐树木、清理土地和通过燃烧清除垃圾。此外,森林树木的不当采伐以及其他对农业和林业土地的滥用正在产生非常不利的影响,包括侵蚀加剧、排水不良、土壤肥力低下以及由此造成的土地生产力低下

A case study for Liberian agroforestry: science and the implementation of a co–management prospectus for agriculture and forestry
The tropical rain forest that is the climax vegetation of Liberia is in need of modern and preferential scientific management practices. Contemporary evaluations say that Liberia’s forest is dwindling, but Liberia still has one of the largest remnants of pristine forests in the world. The Amazon region in Brazil, South America, and the Congo Basin in Central Africa, can boast of larger forests, but the Liberian forest is large and a real economic resource for both agriculture and forestry. Response to the demand for timber, non–timber forest products, mining, and agricultural products is deforestation and land clearing, both of which are taking a negative toll on forest and agricultural lands. Land clearing, including the complete removal of large and otherwise robust trees, is typically imperative. A major focus of small farmers consequently involves tree felling, land clearing, and debris removal by burning. Moreover, improper extraction of forest trees, with other misuse of agriculture and forestry lands, is having very negative effects, including increasing erosion, poor drainage, low soil fertility, and the resultant poor land productivity.1
