An assessment of potential improvements in social capital, risk awareness, and preparedness from digital technologies

Abstract. Contributions to social capital, risk awareness and preparedness constitute the parameters against which applications of digital technologies in the field of disaster risk management should be tested. We propose here an evaluation of four of these, mobile positioning data, social media crowdsourcing, drones and satellite imaging, with an additional focus on acceptability and feasibility. The assessment is carried out through a survey disseminated among stakeholders. The frame of the analysis also grants the opportunity to investigate to what extent different methodologies to aggregate and evaluate the 10 results, the CRITIC model, the dCRITIC model, the Entropy model, the Mean Weight model and the Standard Deviation model, may influence the preference of one technology over the others. We find that the different assumptions on which these methodologies rely deliver diverging results. We therefore recommend future research to be based on a sensitivity analysis that considers multiple and alternatives methods to evaluate survey results.

The authors brought up an important and timely topic: digital technologies for disaster risk reduction (DRR) strategies. However, their current version of the manuscript requires a fundamental review of the concepts, followed by adjustments and improvements in the methodology. I recommend major revision and reconsideration in the future.
Some points:
• Social capital is not a usual concept in geosciences. In the introduction, the authors should define this concept using references.
• The following questions require answers: “How are these digital technologies used currently (what is the state-of-the-art)?”, and “How are these digital technologies can be implemented effectively?” A systematic review can contribute to these answers.
• The analysis and content reflect a North Global perspective. I suggest to mentioned in a specific section the limitations of the research. Some vulnerable groups can become more vulnerable in South Global from the application of digital technologies in the only way. Besides this, inequality in undeveloped countries or developing countries can hamper the wide and fair application of digital technologies. The sentence in line 37: “… the end improve societal resilience among the most vulnerable segments of the population” requires attention.
• More discussion and results analysis are required, such as, whether there is a relation between the knowledge area or profession, or country and the weights. Cluster analysis can be used.Citation: https://doi.org/10.5194/nhess-2023-8-RC1
