This study analyses fuelwood volume and honey yield per hectare of Acacia nilotica plantations in El Ain Forest Reserve in Sudan, and assesses the financial viability of fuelwood-honey enterprises using discounted cash flow analysis. Tree growth data were collected using fixed-radius circular sample plots to estimate wood volumes of present and harvest ages. Key informant interviews of Forest National Corporation staff of North Kordofan State and members of the Trade Union of Fuelwood Producers and Traders provided market-related data. Fuelwood production in A. nilotica plantations generates a negative financial net present value (NPV), but when combined with revenue from honey production provides a positive NPV. The findings also suggest that beekeeping may act as an incentive for sustainable forest management.

苏丹艾因自然森林保护区的金合欢人工林的财务可行性和可持续管理

这项研究分析了苏丹艾因森林保护区的相思木人工林的薪材量和每公顷蜂蜜产量，并使用现金流量折现法评估了薪材蜂蜜企业的财务可行性。使用固定半径的圆形样本图收集树木生长数据，以估计当前和收获年龄的木材体积。北部科尔多凡州森林国家公司员工以及薪材生产者和贸易者工会成员的关键线人访谈提供了与市场有关的数据。薪材生产A.罗非鱼人工林产生了负的财务净现值（NPV），但与蜂蜜生产的收入相结合，则提供了正的NPV。研究结果还表明，养蜂业可能会促进可持续森林管理。
