摘要

摘要 森林和林地资源的可持续性对于确保生态系统、生物多样性和人类社会的长期福祉至关重要。本研究分析了来自三角测量来源的可用数据,这些数据产生了有关当前资产、威胁和机遇的范围和位置的信息,并使用各种统计方法、图像和空间分析以及情景分析进行了分析,以便为极光巴勒的森林和林地(FFL)资源制定和维持适用的管理、养护和保护战略。结果显示,2003 年至 2018 年期间,森林和林地资产发生了显著变化,近期数据显示,郁闭森林仍是该地区的主要植被,同时还有生物多样性、旅游、水资源等其他资产。森林覆盖率的下降趋势是耕地面积扩大的结果,而耕地面积的扩大又伴随着来自自然和人为的几种威胁。人为威胁中最严重的是偷伐木材,其次是木炭制造、杆材采集和木柴采集。这些威胁的驱动因素包括受抚养人的数量、家庭与威胁之间的距离、使用的运输工具以及每项活动所赚取的收入。已识别威胁的社会地理信息表明,人类活动几乎延伸到了每个次级流域的最远部分,这影响了发展和资源可持续利用的机会。资产、威胁和机遇被认为是对子流域进行形势分析时使用的投入,对子流域的使用进行了优先化决定,并制定和提出了可持续的渔业资源管理策略,以便在未来产生最佳的生态、社会文化和经济效益。

Assets, Threats, and Opportunities in Developing and Sustaining the Management of Forest and Forestland Resources of Baler, Aurora, Philippines
Abstract The sustainability of forests and forestland resources is essential in ensuring the long-term well-being of ecosystems, biodiversity, and human society. This study analyzed available data from triangulated sources that produced information about extent and locations of the current assets, threats, and opportunities that were analyzed using various statistical methods, image and spatial analysis, and situational analysis in order to develop and sustain applicable management, conservation, and protection strategies for forest and forestland (FFL) resources of Baler, Aurora. Results revealed that there were significant changes of FFL assets from 2003 to 2018, and the recent data showed that closed forest was still the dominant cover of the area along with other assets like biodiversity, tourism, water resources, and others. The decreasing trend of the forest cover was the result of expansion of cultivated lands that follows the occurrence of several threats both from natural and anthropogenic sources. The most severe among the anthropogenic threats is timber poaching followed by charcoal making, pole timber collection, and firewood gathering. These threats were driven by the number of dependents, home-to-threat distance, conveyances used, and income earned per activity. Social geomatics of the identified threats shows that the human activities had extended almost to the farthest portions of each sub-watersheds that affects opportunities for development and sustainable utilization of resources. Assets, threats, and opportunities were considered as inputs used in situational analysis of sub-watersheds of which prior-itization of use was decided and FFL management strategies were developed and proposed to be sustained in order to produce optimum ecological, socio-cultural, and economical benefits in the future.
