Rice (Oryza sativa ) is the second staple food largely grown and widely consumed\nin Pakistan. About 10% of the total crop area of Pakistan is cultivated\nby rice that takes a part in value addition of almost 1.3% - 1.6% in the total\nGross Domestic Product (GDP). Due to global warming, temperature has a\nprofound impact on rice crop phenology. Low temperature is the main factor\nof delay in rice plant growth and very high temperature results in stressed and\nshort heighted plant so the crop sown in a region at the same time is not ready\nto harvest at same hours but a delay is observed. The study area under investigation\nwas district Sheikhupura, Nankana, Lahore, Gujranawala and Hafizabad,\nwhich are famous for rice productivity. Landsat 7, 8 freely available\nthermal dataset are used to calculated pixel based temperature values to evaluate\ngrowth using agricultural growth indicators. The total covered area was\n13,480 km2 in which 484 km2 area was marked as less growth rate area with\nlow temperature values due to water body and excess of vegetation over there.\nAbout 7960 km2 area is marked as good for growth experiencing optimum\ntemperature for rice plant. Approximately 4944 km2 area is marked as stressed\nrice plant area experiencing high temperature values adjacent to urban population.\nAn attempt is made here to map this effect of temperature-based\ngrowth variability of the rice plant across the study area.
