在气候变化的背景下，毁林是一个严重的威胁，建立森林保护区是养护和管理森林的一项关键战略。本研究旨在调查槟榔叶种植对孟加拉国南部沿海地区Teknaf野生动物保护区的影响。研究目的是描述保护区内及周边槟榔叶的种植程度，确定其对森林的影响，描述影响槟榔叶种植的社会经济因素。数据收集于2015年至2017年，涵盖Teknaf upazila （upazila是一个行政单位）的4622户家庭。对卫星图像进行了分析，以确定耕作对森林的影响。在分析的影响槟榔叶种植的因素中，家庭规模、森林占用和入侵对槟榔叶种植有显著影响。本研究共发现槟榔叶种植样地4273个，占地250.74 ha，其中在林地内发现1264个，占地59.76 ha。一个paan borj的平均面积为0.06公顷，总共需要1.32吨来自森林的木杆。当地居民对森林资源的过度依赖给保护森林带来了压力，造成了严重的森林砍伐。例如，可持续的资源利用，遵循以树木为基础的农林复合系统和采用更可持续的槟榔叶种植方法，可以减少受保护森林内的森林砍伐并保护生物多样性。
Deforestation is a severe threat in the context of climate change and the establishment of protected forest areas is a crucial strategy to conserve and manage forests. This study aims to investigate the impact of betel leaf cultivation on the protected forest area known as the Teknaf Wildlife Sanctuary in the southern coastal area of Bangladesh. The research objectives were to describe the extent of betel leaf cultivation in and around the protected forest area, determine its impact on the forest and describe the socioeconomic factors affecting the cultivation. Data were collected from 2015 to 2017 covering 4622 households in the Teknaf upazila (upazila is an administrative unit). Satellite images were analyzed to determine the impact of cultivation on the forest. Among the factors analyzed the determinants of betel leaf cultivation, family size, occupation and encroachment in the forest were found to have a significant impact. This study identified 4273 paan boroj (betel leaf cultivation plots) covering an area of 250.74 ha, among which 1264 were found inside the forest area occupying 59.76 ha forestland. The average size of a paan boroj was 0.06 ha and in total required 1.32 tons of wooden poles from the forest. Over dependency by local people for their livelihood on forest resources is creating pressure on the protected forest and causing severe deforestation. Sustainable resource use, for example, following a tree-based agroforestry system and adopting more sustainable approaches for betel leaf cultivation, can reduce the deforestation inside the protected forest and conserve biodiversity.
