Equity is an essential element in the implementation of policies related to ecosystem services. With the rapid expansion of commercial land use into tropical forest regions, the urgency and importance to integrate equity issues in space and time in decisions and actions stand without doubt. However, data scarcity in these regions limits the understanding of factors that affect spatial and temporal aspects of equity. This again emphasizes the need of rapid and robust ways to address spatio-temporal patterns of equity that are especially suited for data-scarce regions. This study addresses this gap. We assess the factors that have an influence on spatial equity through an empirical study that compares two sub-regions in the Upper Suriname River Basin. In the first sub-region, some logging and road building occur; the other, however, is more remote and such interventions are not yet developed but merely planned. We collected spatial data for 1995 and 2015 using a participatory GIS survey (n = 493), registering provisioning service hotspots. We then explored spatial equity, according to clan and authority position, by analyzing variation over time and across regions in relation to access capabilities of these users. In the region with roads and logging, spatial equity concerns emerged over time regarding the provision of timber and fish. In the remote region, spatial inequity in access to fish provisioning hotspots of ecosystem services increased while it showed a decreasing trend for timber. In outlining spatial equity concerns, we argue that spatial equity analysis unveils an essential social dimension in the use of the space that is integral in spatial planning processes in data scarce forest regions under external pressures.

公平是执行与生态系统服务有关的政策的基本要素。随着商业土地用途迅速扩展到热带森林地区，毫无疑问，紧迫性和重要性将时空公平问题纳入决策和行动。但是，这些地区的数据匮乏限制了人们对影响公平的时空方面的因素的理解。这再次强调了需要快速而强大的方法来解决特别适合于数据稀缺地区的时空公平模式。这项研究解决了这一差距。我们通过比较苏里南上游流域两个子区域的实证研究，评估了影响空间公平的因素。在第一个分区，发生了一些伐木和修路工作。但是，另一个 距离较远，此类干预措施尚未制定，只是计划而已。我们使用参与式GIS调查（n = 493）收集了1995年和2015年的空间数据，并注册了供应服务热点。然后，我们根据氏族和权威的位置，通过分析与这些用户的访问能力相关的随时间和跨区域的变化来探索空间公平性。在道路和伐木区，随着时间的推移，人们对木材和鱼类的供应越来越关注空间公平。在偏远地区，获得生态系统服务的养鱼热点地区的空间不平等现象加剧，而木材却呈下降趋势。在概述空间公平问题时，
