Fig. 5: Exposure reduction for all cities across the different climate zones.
The x-axis displays the four climate zones: Temperate, Arid, Continental, and Tropical (C1, C2, C3, and C4, respectively). A Show the values of the total exposure reduction (ΔTET(%)) for all cities with an increment of the Normalized Difference Vegetation Index (NDVI) of 0.3. B We show the aggregated values of ΔTET(%) for the different climate zones. C We compare the global NDVI increment required to achieve exposure reduction by targeting the entire city versus the most populated pixels. Scenario 1 shows a global NDVI increment to achieve exposure reduction by targeting the entire city, while in Scenario 2, NDVI is increased only in the most populated pixels as described in Fig. 4. D We present the average and standard deviation of the local NDVI increment for Scenario 1 to achieve the same exposure reduction with a homogeneous increment of 0.3. E The plot displays the average and standard deviation of the exposure reduction for different values of NDVI increment for all cities in the different climate zones. F We show the relative NDVI savings achieved by targeting the most populated areas for different values of NDVI increment. G We present the difference between the local and global NDVI increments for different values of global NDVI increment. See data availability and code availability for publicly available dataset and codes for generating the figures.
