GIS based analysis of agricultural production (Wheat), water estimation and effects of climate change on Gujranwala, Pakistan from 2008 to 2018
Abstract
This study examines the temporal analysis change in agricultural activities of Gujranwala, Pakistan. Global warming is expected to have an intense effect on earth’s environment and vegetation overwhelm the distribution and abundance of food. Past researches explains the ability of different crops to cope up according to the magnitude of temperature change and their phenology. Pakistan is located in tropical region majorly, wheat crop is extensively produced and generates a lot of income for farmers. This research evaluates the increase of wheat crop in Gujranwala from 2008 to 2018 for the month of November. For this purpose vegetation cover or agricultural activities were monitored for said period by using Remote Sensing (RS) and Geographic Information Systems (GIS). LANDSAT 8 (30m per pixel) for both years were taken for analysis and to thematically map results. This research considers three parameters which includes Land Use and Land Cover (LULC) of Gujranwala in relation with Normalized difference Vegetation Index (NDVI). In addition, assimilation of surface soil moisture was another focus part of this study in order to create water demand estimation for agriculture.
