Although the Government of Indonesia has good data on forest cover and population, it does not have data on how many people live on state-claimed forest land. The objective of this study was to assess the extent of this deficiency and to develop a methodology for overcoming it, based on field research in the province of West Kalimantan. The project retrieved and combined government data on forests and people, analysed their significance in terms of numbers of forest-dwelling people, compared these results with government estimates and an empirical field-check, and sought to explain why knowledge of forest dwellers on state-forest lands is problematic. Results suggest that 20 to 30% of the population of West Kalimantan (approximately 650 000 to one million people) live on state-claimed forests. The main reason why it is difficult to determine how many people live on state-claimed forest lands is that a large number of villages remain unmapped and thus it is not possible to unite census data with forest boundaries in a spatially-precise manner. While the Indonesian Ministry of Forestry has not placed a high priority on determining how many people live on state-claimed forests, this study suggests that the lack of information on forest population densities is as much a consequence of the lack of information on village locations as it is a result of political or institutional interests.

印度尼西亚西加里曼丹的森林居民人口统计数据

尽管印度尼西亚政府有关于森林覆盖率和人口的良好数据，但它没有关于有多少人生活在国有林地上的数据。这项研究的目的是评估这一缺陷的程度，并根据西加里曼丹省的实地研究制定克服这一缺陷的方法。该项目检索并结合了有关森林和人口的政府数据，分析了它们在森林居住人口数量方面的重要性，将这些结果与政府估计和实证实地检查进行了比较，并试图解释为什么森林居民对国家-林地是有问题的。结果表明，西加里曼丹 20% 至 30% 的人口（约 65 万至 100 万人）生活在国有森林中。难以确定有多少人生活在国有林地上的主要原因是大量村庄仍未绘制地图，因此无法以空间精确的方式将人口普查数据与森林边界统一起来。虽然印度尼西亚林业部没有高度重视确定有多少人生活在国有森林中，但这项研究表明，缺乏有关森林人口密度的信息，与缺乏有关村庄位置的信息一样重要。这是政治或制度利益的结果。
