基于森林生态系统商品的苏丹森林蜂蜜生产的社会和经济价值评估研究

发布时间:2021-03-08 05:21
  苏丹的养蜂活动在社会、经济和环境方面发挥着重要作用。(Blue Nile,White Nile,South Kordofan,West Kordofan,South Darfur,West Darfur,El-Gadarif and Sennar)它们以产蜜量高而闻名,而且由于养蜂活动在森林中广泛开展,它们的森林覆盖率很高。森林生态经济评价的应用为森林经理、养蜂人和决策者提供了当前的信息以及有助于对养蜂活动及其伴生树种进行有效管理的数据。本研究从养蜂的角度确定了养蜂活动中的大多数森林树种,估计和评价了这些物种的经济价值。另外,净现值(NPV)应用于薪柴和蜂蜜的生产尼罗金合欢人工林此外,研究还强调了养蜂活动在森林管理应用中的整合。本研究采用立意取样法,确定本研究地区的目标人群。在一年的生产季节(2016-2017年),我们对选定的八个苏丹州(n=105)的养蜂人进行了一次访谈,使用结构化问卷收集所需数据。。此外,还进行了田间试验和实际试验,估算了木柴产量和蜂蜜产量在El Ain森林保护区,位于Shiekan地区,Kordofan省,百分比被用来确定最重要的森林树种的养蜂活动,并估计蜂蜜产...
