Abstract
To assess the greenery dynamics, the relationship between population changes
and variation in normalized difference vegetation index (NDVI) was observed. For
this purpose, three major metropolitan cities (Bahawalpur, Sahiwal, Gujranwala)
of Punjab, Pakistan were studied. Land-satellite images of these cities from year
1981 to 2020 were processed to extract the NDVI data of forty years; the value of
NDVI falls between 1 to -1. Data of climatic variables (temperature, rainfall,
humidity, wind) and anthropogenic factors (population, population growth-rate)
were also collected. This study quantified the fact that population increase is
significantly reducing vegetation(NDVI).
