Natural hazards are becoming increasingly frequent within the context of climate change—making reducing risk and building resilience against these hazards more crucial than ever. An emerging shift has been noted from broad-scale, top-down risk and resilience assessments toward more participatory, community-based, bottom-up approaches. Arguably, non-scientist local stakeholders have always played an important role in risk knowledge management and resilience building. Rapidly developing information and communication technologies such as the Internet, smartphones, and social media have already demonstrated their sizeable potential to make knowledge creation more multidirectional, decentralized, diverse, and inclusive. Combined with technologies for robust and low-cost sensor networks, various citizen science approaches have emerged recently as a promising direction in the provision of extensive, real-time information for risk management. It can serve as a means of educating and empowering communities and stakeholders that are bypassed by more traditional knowledge generation processes.
This Research Topic compiles 13 contributions that interrogate the manifold ways in which citizen science has been interpreted to reduce risk against hazards that are
water-related (i.e., floods, hurricanes, drought, landslides);
deep-earth-related (i.e., earthquakes and volcanoes); and
responding to global environmental change such as sea-level rise.
Then were analysed the particular failures and successes of natural hazards-related citizen science projects: the objective is to obtain a clearer understanding of “best practice” in a citizen science context.
