Darker shades indicate greater levels of SDG achievement at risk. The cumulative column (far right) shows the dominant hazard most affecting the representative SDG indicator in each upazila. The cumulative row (bottom) denotes the SDG most threatened by each type of hazard, based on its current progress level and magnitude of potential exposure to the hazard. Note: cyclone shelters are purpose-built to withstand cyclone winds, hence their exposure to cyclones is not considered a threat to progress towards the SDG 13 indicator (directly affected persons); they are, however, considered vulnerable to impacts of coastal and river flooding and erosion.
