摘要

在印度尼西亚总共1500万公顷的油棕种植园中,约有250万公顷种植在森林地带,或与森林地带相冲突。油棕种植园面临着社会经济和生态问题的冲突。本研究在占壁的Harapan雨林进行,通过考虑社会经济和财政可行性以及生物多样性和土地覆盖,评估以油棕为基础的农林业协调经济和生态利益的潜力。采用现金流折现法,采用净现值(NPV)、效益成本比(BCR)和内部收益率(IRR)三个指标,将油棕农林复合经营的财务可行性与油棕单一栽培进行比较。以占碑油棕农林业试验田为研究对象,对生物多样性和土地覆被两项生态指标进行了评价。本研究表明,油棕单一栽培的NPV、BCR和IRR分别为62,644,836印尼盾(4,476.84美元)、1.39和20.77%,而试验田种植的油棕农林业的NPV、BCR和IRR分别为209,221,212印尼盾(14,951.76美元)、1.79和24.42%,具有更好的财务指标价值。除了评估经济可行性外,我们还发现,通过对现有研究的回顾,油棕农林业具有积极的生态影响,如增加森林土地覆盖,无脊椎动物和鸟类多样性。

Evaluating the feasibility of oil palm agroforestry in Harapan Rainforest, Jambi, Indonesia
About 2.5 million hectares of a total of 15 million hectares of oil palm plantation in Indonesia are planted in, or conflict with, the forest zone. Oil palm plantations face a conflict between socio-economic and ecological issues. This study was conducted in the Harapan Rainforest, Jambi to evaluate the potential of oil palm-based agroforestry to reconcile economic and ecological interests, by considering socio-economic and financial feasibility as well as biodiversity and land cover. The financial feasibility of oil palm agroforestry is compared to oil palm monoculture, employing a discounted cash flow approach using three indicators: net present value (NPV), benefit-cost ratio (BCR), and internal rate of return (IRR). Two ecological indicators—biodiversity and land cover—are evaluated in an experimental plot of oil palm agroforestry in Jambi. This study indicates that the NPV, BCR, and IRR of oil palm monoculture are IDR 62,644,836 (US$ 4,476.84), 1.39, and 20.77%, respectively, while the oil palm agroforestry planted in the experimental plot potentially generates much better values of financial indicators with NPV, BCR, and IRR being IDR 209,221,212 (US$ 14,951.76), 1.79, and 24.42%, respectively.  Besides evaluating financial feasibility, we also found that the reviewed current studies indicate that the oil palm agroforestry provides positive ecological impacts, such as increased forest land cover, invertebrate fauna, and bird diversity.
