摘要

这项研究是在Mapfungautsi森林中进行的,目的是确定从2000年(卫星图像没有检测到森林砍伐)到2020年的森林砍伐程度,并收集森林周围社区成员对森林砍伐因素的看法。采用了遥感技术、问卷调查和关键信息提供者访谈形式的混合方法来收集数据。结果表明,在第一个十年(2000 - 2010)和第二个十年(2000 - 2020)后,森林砍伐面积分别为4254ha(5%)和10632ha(14%)。20年后,受影响最大的植被类型是林草(84%),其次是灌木林(31%)和林地(10%)。受访者认为,政治利益、酋长管辖范围的扩大和人口压力是导致马普丰高茨森林砍伐加速的主要社会因素。相反,确定的主要导致森林砍伐的经济因素是农业、木材和柴火偷猎。该研究的结论是,农业是造成森林砍伐的唯一最具影响力的因素,因为主要的社会因素(政治利益和酋长统治的扩大)共同作用,入侵和清除受保护的森林,用于定居和农业(这也是当地人民的主要生计来源)。因此,任何遏制马丰高茨森林和任何其他受保护森林砍伐的控制措施,都需要政治和传统领导人以及农民和社区成员等其他利益攸关方的认真支持和意志力。

An Assessment of the Factors Responsible for the Extent of Deforestation in Mapfungautsi Forest, Zimbabwe
This study was conducted in Mapfungautsi forest to determine the extent of deforestation from the year 2000 (when no deforestation was detected by satellite imagery) up to 2020, as well as to gather perspectives from members of communities around the forest, on factors responsible for deforestation. A mixed method approach in the form of remote sensing techniques, questionnaires and key informant interviews was used to gather data. Findings indicated the extent of deforestation to be 4254ha (5%) and 10632ha (14%) after the first decade (2000 – 2010) and second decade (2000 – 2020) respectively. Of the cleared forest, the most affected vegetation cover type was the wooded grassland (84%) followed by bushland (31%) and wooded land (10%) after the 20-year period. Respondents identified political gain, expansion of jurisdictions of chiefs and population pressure as the social factors most responsible for accelerated deforestation in Mapfungautsi. Conversely, the identified economic factors mainly contributing to deforestation were agriculture, timber and firewood poaching. The study concluded that agriculture was the single most impactful factor responsible for deforestation as the main social factors (political gain and expansion of chieftaincy) worked in combination to invade and clear protected forests for settlement and agriculture (which is also the main livelihood source of local people). Consequently, any control measures to arrest deforestation in Mapfungautsi and any other protected forests for that matter, will require serious buy-in and will power from political and traditional leaders and other stakeholders like farmers and community members.
