摘要

发展中国家农村地区的固体废物管理面临着重大挑战,原因是经济拮据和人类住区不规则。这些因素往往导致未经授权的垃圾处理场的出现,给人类健康、生态系统和经济带来风险。遥感和地理信息系统技术为了解与城市固体废物(MSW)处置不当相关的复杂问题提供了一种手段。本研究旨在通过研究地表温度(LST)和植被指数,确定墨西哥金塔纳罗奥州南部农村地区未经授权的垃圾处理场,并将其作为未经授权的最终垃圾处理场(FDS)的潜在指标。研究结果表明,13% 的研究区域存在未经授权的垃圾处理场的可能性较高、中等或较低。此外,还确认了 3 个经授权的最终弃置点,以及 20 个未经授权的弃置点。LST 和归一化差异植被指数能有效检测出未经授权的地点,因为与邻近地区相比,这些地区的温度较高,植被活力较弱。这些结果为了解与农村地区垃圾处理不当有关的问题提供了有价值的见解,并提供了有助于优化城市固体废物管理和减轻其对环境和健康影响的信息。

Spatial analysis to identify unauthorized municipal solid waste disposal sites in rural areas of southern Mexico.

The management of solid waste in rural areas of developing countries faces significant challenges due to economic constraints and irregular human settlements. These factors often lead to the creation of unauthorized disposal sites, which pose risks to human health, ecosystems and the economy. Remote sensing and geographic information system techniques provide a means to understand the complex issues associated with inadequate municipal solid waste (MSW) disposal. This study aimed to identify unauthorized disposal sites in the rural areas of southern Quintana Roo, Mexico, by examining land surface temperature (LST) and vegetation indices as potential indicators of unauthorized final disposal sites (FDSs). The findings reveal that 13% of the study areas have a high, moderate or low probability of hosting unauthorized disposal sites. Additionally, 3 authorized final disposal sites (FDSs) were confirmed, and 20 unauthorized sites were identified. LST and the normalized difference vegetation index were effective in detecting unauthorized sites, as these areas exhibited higher temperatures and less vigorous vegetation compared to adjacent areas. The results provide valuable insights into the issues associated with inadequate waste disposal in rural areas and offer information that can help optimize MSW management and mitigate its environmental and health impacts.
