Spatiotemporal Impact of Precipitation Trend on LULC Using Satellite Remote Sensing Technique in Khirthar National Park, Sindh Pakistan

Abstract

: Water footprint techniques are extensively used for essential life chores. It also maintains the naturalecosystem. The variations in climatic spell are not only important to investigate the past and current scenarios, but it isalso useful to develop the water resource projects. The current study explored the spatial-temporal climatic variation ofdry and wet periods (between 1998 and 2010) using the digital image processing technique of ENVI (Environment forVisualizing Images) classics, satellite remote sensing g (SRS), and GIS. The results are organized for the reported periodi.e. between 1998 and 2010, showing the change detection of the hydrological effect in the dry and wet years. It shows asignificant change in the land use land cover (LULC) of vegetation, water, settlement, and ephemeral rivers followed by91%, 97.45%, 94.40%, and 62.94 % respectively through the wet year of 2010, in association with the dry period of1998. For more authentications, the Normalized Difference Vegetative Index (NDVI) image difference of the wet anddry period has also been evaluated, which has shown vegetation in large areas with more water potential in the wet year2010. The water potential can be used by diverting it to the natural depressions, ditches, and ponds for storage purposesand to increase recharge of groundwater by increasing its quality and quantity. The stored water could be utilized in thedrought-prone days for sustainable agriculture activities, to reduce the migration rate of the community, and to improvethe socio-economic conditions in the study area of Khirthar National Park.
