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
