摘要

印度尼西亚南苏门答腊岛的Ogan Komering Ilir森林保护区(OKIPF)由于广泛的土地转化为水产养殖池塘而发生了严重的森林退化。这种退化对红树林生态系统和当地社区的社会经济福祉产生了深远的不利影响。为了解决这个问题,已经实施了一项森林捕捞制度,作为减少非法土地转换的战略,同时提高了社区福利。本研究旨在评估森林渔业对经济可持续性和红树林保护的影响。本研究采用定量描述的方法,通过有目的的抽样,对65名参与者进行了调查,包括池塘农民、农民团体领导人、林业官员和社会林业促进者。利用垂直于海岸线100-200 m的样带收集生态数据,分析红树林植被和高经济价值物种。采用归一化植被指数(NDVI)评价生态条件。通过收入分析、收入成本比、盈亏平衡点、净现值、净收益成本比和内部回报率来评估经济可持续性。福利水平是用百分比分析和贫困阈值来评估的。结果表明,森林渔业系统有助于恢复红树林的生物多样性和生态功能,同时改善塘农的经济条件。方差分析进一步支持了银鱼养殖池与非银鱼养殖池之间的显著差异。该研究的结论是,森林捕捞为平衡短期经济需求和长期生态目标提供了一个可行的模式。它提出了一种解决森林退化问题的方法,并倡导利益攸关方进行强有力的合作,将林业作为一种可持续森林管理方法。

Economic and environmental sustainability in silvofishery of mangrove ecosystem in Ogan Komering Ilir Protected Forest, Ogan Komering Ilir Regency, Indonesia

The Ogan Komering Ilir Protected Forest (OKIPF) in South Sumatra, Indonesia, has undergone significant forest degradation due to widespread land conversion into aquaculture ponds. This degradation has had a profoundly adverse impact on the mangrove ecosystem and the socioeconomic well-being of local communities. To address this, a silvofishery system has been implemented as a strategy to reduce illegal land conversion while enhancing community welfare. This study aims to evaluate the impact of silvofishery on both economic sustainability and mangrove forest conservation. Employing a quantitative descriptive approach through surveys, the study engaged 65 participants through purposive sampling, including pond farmers, farmer group leaders, forestry officials, and social forestry facilitators. Ecological data were collected using transects (100–200 m perpendicular to the coastline) to analyze mangrove vegetation and species of high economic value. The Normalized Difference Vegetation Index (NDVI) was used to assess ecological conditions. Economic sustainability was evaluated through income analysis, revenue-cost ratio, break-even point, net present value, net benefit–cost ratio, and internal rate of return. Welfare levels were assessed using percentage analysis and poverty thresholds. Results demonstrate that the silvofishery system contributes to restoring mangrove biodiversity and ecological functions while improving the economic conditions of pond farmers. ANOVA analysis further supports significant differences between silvofishery and non-silvofishery ponds. The study concludes that silvofishery offers a viable model for balancing short-term economic needs with long-term ecological goals. It introduces an approach to addressing forest degradation and advocates for strong stakeholder collaboration to introduce silvofishery as a sustainable forest management approach.

期刊介绍: Agroforestry Systems is an international scientific journal that publishes results of novel, high impact original research, critical reviews and short communications on any aspect of agroforestry. The journal particularly encourages contributions that demonstrate the role of agroforestry in providing commodity as well non-commodity benefits such as ecosystem services. Papers dealing with both biophysical and socioeconomic aspects are welcome. These include results of investigations of a fundamental or applied nature dealing with integrated systems involving trees and crops and/or livestock. Manuscripts that are purely descriptive in nature or confirmatory in nature of well-established findings, and with limited international scope are discouraged. To be acceptable for publication, the information presented must be relevant to a context wider than the specific location where the study was undertaken, and provide new insight or make a significant contribution to the agroforestry knowledge base
