Logo of CCVI Climate—Conflict—Vulnerability Index

Heatwaves are periods of abnormally hot weather. They last for at least three days. By impacting mortality and morbidity, labor productivity, and crop yields, heatwaves particularly drive risks related to human health and food security. This indicator measures the total number of heatwave days over the past 7 years in a grid cell.

    Quarterly data update

    Feature updates
    • Due to the dissolution of USAID, FEWS data is no longer available. Food insecurity is now only based on UN SDG indicators.
    • Conflict indicators no longer contain additional population-based exposure. Since conflict occurrence and data collection is already correlated with population, conflict data is assumed to have built-in exposure. For more details, refer to the technical documentation.
    • Surrounding violence and Surrounding popular unrest now count water as zeros in their calculation.
