               Abstract

               The land surface temperature (LST) is a phenomenon in which an urban system’s microclimate
               heats up expressively quicker than its rural environments. The development of built-up areas
               has a significant impact on land use/land cover (LULC) by changing the vegetation area into
               commercial and residential regions as well as their related infrastructure; this escalates the LST.
               The main objective of this research is to study the effect of LULC changes on LST of Southern
               Punjab by using remote sensing (RS) data. Temporal satellite datasets for the years (1987,
               1997, 2007 and 2017) were used for the identification of LST and vegetation indices in study
               area. Landsat images were also used to compute the LST, normalized difference built-up index
               (NDBI),  normalized  difference  vegetation  index  (NDVI)  and  normalized  difference  water
               index (NDWI) maps. The built-up area was increased from 29620 ha (3.63 %) to 88038 ha
               (10.8 %) between the years 1987 to 2017. In the years 1987, 1997, 2007 and 2017, LST values
                                                                                o

               study, regression coefficients (R ) between NDVI and LST 0.81, 0.78, 0.84 and 0.76 were
               observed in 1987, 1997, 2007 and 2017 respectively. This research shows that NDWI and
               NDVI correlated negatively with less LST but NDBI correlated positively with high LST. The
               result of this study also provides vital information about LULC, LST and will help policy
               makers to develop policies to effectively manage the land resources.
