有效减少灾害风险往往因为普遍缺乏收集的关于灾难性事件的可靠数据而受到阻碍，尤其是在全球南方。因此，有必要采取新的办法来缓解这一制约，特别是在减少广泛风险方面。Ageo-ObservernWork由21名记者组成，于2017年2月在卢旺达地区(乌干达)成立，利用智能手机技术收集八种不同灾害的数据。在 运行的前15个月内，总共提交了319份灾难报告。绝大多数报告的灾害是地理观察员在灾害发生后2 天内到达的。对报告活动的分析显示出很大的差异，最活跃的地理观察员占所有报告的近75%。通过使用现有的滑坡易感性地图作为预期滑坡流行率的替代指标，这种报告差异被证明至少在一定程度上是由灾害发生的差异造成的。在地理观察员中进行的一项调查结果证实了这一点。调查结果还显示，参与者更多的是受到非金钱利益的驱使，而不是经济补偿。在 运作的头15个月期间收集的数据表明，该区域的广泛风险被低估，并表明参与性遥感的附加值，以弥补目前缺乏运作良好的官方数据收集机制。这一试点项目是参与式遥感的概念证明，即使在智能手机技术通常不被采用的偏远环境中，也可以收集高质量的数据。它可以作为其他区域的先例或榜样，在这些区域，人们对广泛的风险知之甚少，但对人口构成重大威胁。
Effective disaster risk reduction is often hampered by a general scarcity of reliable data collected on disastrous events, particularly in the Global South. Novel approaches are therefore necessary to alleviate this constraint, particularly with regard to reducing extensive risks. Ageo-observernetwork, consisting of 21 reporters, was established in the Rwenzori region (Uganda) in February 2017 to collect data on eight different disasters using smartphone technology. Within the first 15 months of operation, a total of 319 disaster reports were submitted. A large majority of the reported disasters were reached by the geo-observers within 2 days after their occurrence. The analysis of reporting activity shows a large divergence, with one third of the most active geo-observers accounting for nearly 75% of all reports. By using an existing landslide susceptibility map as a proxy of expected landslide prevalence, this reporting divergence is demonstrated to be at least partially driven by a difference in disaster occurrences. This is confirmed by the results of a survey held among the geo-observers. Survey results also showed that the participants are more driven by non-pecuniary benefits rather than financial compensation. The data collected during the first 15 months of operation indicates that extensive risks in the region are underestimated and demonstrates the added value of participatory sensing to compensate for the current lack of well-functioning official data collection mechanisms. This pilot project is a proof of concept for participatory sensing to collect high quality data even in remote contexts where smartphone technology is not generally adopted. It can serve as a precedent or example for other regions where extensive risks are poorly understood but pose significant threat to the population.
