Agricultural development is a leading cause of habitat destruction that increasingly threatens global biodiversity. To help understand the likelihood and implications of agricultural expansion in areas of high conservation importance, this article examines agricultural suitability in forested portions of biodiversity hotspots and tropical wilderness areas, regions with especially rich concentrations of species found nowhere else. The study employs geographic information system technology to examine suitability for six crop categories in selected conservation localities worldwide: those portions of regions containing high biodiversity, protected areas (e.g. national parks) within these regions, and 10-km bands around the protected areas that are dominated by forest. Analyses reveal low suitability for most crop categories under both commercial and subsistence scenarios, with a few exceptions. In most cases, adequate planning can enable the coexistence of agriculture and biodiversity without compromising either.
农业发展是栖息地破坏的主要原因，日益威胁着全球生物多样性。为了帮助理解在具有高度保护重要性的地区进行农业扩张的可能性及其影响，本文研究了生物多样性热点地区和热带荒野地区森林部分的农业适宜性，这些地区是物种特别丰富且在其他地方找不到的区域。该研究采用地理信息系统技术，考察全球选定保护地区内六种作物类别的适宜性：这些地区中生物多样性高的部分、这些地区内的保护区（如国家公园）以及以森林为主的保护区周围10公里地带。分析表明，在商业和自给自足两种情况下，大多数作物类别的适宜性都较低，只有少数例外。在大多数情况下，合理规划能够使农业与生物多样性共存，而不会对任何一方造成损害。
