Abstract
We designed an original survey instrument to study the impact of the floods that heavily hit Emilia Romagna and Tuscany in 2023, and the preparedness to extreme climatic events. The goal of the study is to assess how extreme climatic events affected individuals’ choices and future prospects, including preparedness to future extreme climatic events.

Primary Outcomes

Primary Outcomes (end points)

- Perceptions of climate change
- Worries and concern about climate change
- Perceived probability that, in the next five years, in one’s municipality of residence policies and interventions to cope with the effects produced by extreme weather events will be implemented.
- Perceived probability that, in the next five years, in Italy national level policies and interventions to cope with the effects produced by extreme weather events will be implemented.
- Perceived probability to be impacted by extreme weather events in the next five years
- Opinions about climate change mitigation policies and actions
- Individuals’ climate change mitigation efforts: current adoption and future intention

Experimental Design

Experimental Design
Using an online map and description text, we provide information on the hydraulic hazard in the municipality of residence to half the sample (treatment group), and we provide no information to the other half of the sample (control group). The assignment to the treatment group is done randomly by a computer. We compare the impact of this information provision on several primary outcomes, which we have described above.
Experimental Design Details
Randomization Method
Randomization done in office by a computer.
Randomization Unit
Individual respondent.
Was the treatment clustered?
No

Experiment Characteristics

Sample size: planned number of clusters
The unit of analysis is the individual respondent. We have a sample size of 3400 individuals and we have no clusters.
Sample size: planned number of observations
3400 individuals
Sample size (or number of clusters) by treatment arms
Half of the sample in the control group, and the other half treated. So, around 1700 in each group.
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
