The community-based forest management program has been successful in the conservation of forest cover in Nepal. We investigated forest cover change for the Mechinagar and Buddhashanti Landscape (MBL) area within the Jhapa district, Nepal, during 1990-2019 using Landsat images and GIS tools and valuated the major ecosystem services (ES) of Kalika Community-managed Forest (KCF) within the MBL landscape using the economic approach-market price method (revealed price). Land cover analysis of the MBL area indicated that over the study period, there were increases in urban/built-up areas, forest, and tea plantations, and declines in cultivated land, shrub, barren land, water body, and grassland areas. In particular, forest cover increased by 8.6% from 41.5 sq.km to 45.1 sq.km, due to the conversion of 3.9 sq.km cultivated land and 2.4 sq.km shrub into forest cover. KCF, the selected case study area for ES valuation, has been successful in providing noticeable economic benefits from provisioning and cultural services. Of the provisioning services, wood and timber make the largest contribution with an average revenue collection of Nepali Rupees (NRs) 3091.4 thousands followed by non-timber forest products (NRs 883.1 thousands) and firewood (NRs 524.3 thousands), respectively, while ecotourism-based income is also important (NRs 458.4 thousands) and is increasing in later years. As monitoring forest cover in a rapidly changing landscape and evaluating the ES of the community-managed forest cover are imperative for sustainable environmental planning and policy formulation, these research outputs are expected to be a significant benchmark for planners, policy makers, and future researchers.
基于社区的森林管理项目在尼泊尔的森林覆盖保护方面取得了成功。我们利用 Landsat 图像和 GIS 工具,调查了尼泊尔贾帕地区 Mechinagar 和 Buddhashanti 景观(MBL)地区的森林覆盖变化,并利用经济方法-市场价格法(揭示价格)对 MBL 景观内的 Kalika 社区管理森林(KCF)的主要生态系统服务(ES)进行了评估。MBL 地区的土地覆盖分析表明,在研究期间,城市/建成区、森林和茶园的面积增加,而耕地、灌木、荒地、水体和草地的面积减少。特别是,由于 3.9 平方公里耕地和 2.4 平方公里灌木转化为森林覆盖,森林覆盖面积增加了 8.6%,从 41.5 平方公里增加到 45.1 平方公里。作为 ES 估值的选定案例研究区,KCF 成功地从供应和文化服务中获得了显著的经济效益。在供应服务中,木材和木材的贡献最大,平均收入为尼泊尔卢比(NRs)3091.4 千万卢比,其次是非木材森林产品(NRs 883.1 千万卢比)和薪材(NRs 524.3 千万卢比),而基于生态旅游的收入也很重要(NRs 458.4 千万卢比),并且在近几年呈上升趋势。由于监测快速变化景观中的森林覆盖并评估社区管理森林覆盖的 ES 对于可持续环境规划和政策制定至关重要,因此这些研究成果有望成为规划者、决策者和未来研究人员的重要基准。
