“…Spatial interpolation is widely used in trend mapping e.g., the weather experts use interpolation to construct weather maps to determine temporal variations in rainfall, temperature, humidity or pressure for a specific time span [17]. There are basic three types of spatial interpolations that include Inverse Distance Weightage (IDW), Kriging and Spline [18]. We can accept or reject any of the technique depending upon the application for which we are applying it.…”

Liquified Natural Gas (LNG) has become a basic energy source which is mainly used to run industrial wheel. It has played a vital role for boosting economic growth/GDP of Pakistan. Most of power plants and industries use LNG for generation of commodities of domestic use. The contribution of LNG in the total energy supply is 38% which increases up to 40% in winter. This research was conducted in Rana Town Ferozwala. We selected this area because of non-availability of Sui Northern or Southern network of gas pipelines. We used spatial interpolation technique to map the sale of LNG at various sale points throughout the year 2017. We observed the maximum sale of LNG during winter season (Nov-April) where the LNG demands exceeded from 13.2 tons as compared to the normal 8 tons. It was observed that the LNG demand was declined below the approximated demand e.g., a very less amount of LNG was consumed during June and July which was (2.7-6.9) tons and (2.9-6.7) tons respectively that must be more than 8 tons. On field observation we found that most of people prefer the usage of biofuel instead of LNG in summer season because there is excess of dry residue of animals and the dry wood as well for cooking. This trend analysis determines the LNG consumption across a region where interpolation technique proved efficient in public trend mapping for purchase of LNG during 2017.

“…Subtropical regions are mostly hit by these events [5]. The crop phenology has put huge pressure on small farmers to grow healthy for obtaining sufficient grains which is enough to cater the weeds of increasing population [6]. Therefore, it is important to estimate the exact volume of net productions which make a decision maker to construct a concrete strategy for sustainable development [7,8].…”

Smallholder farmers are threatened by various vulnerable risks which include hostile weather conditions, rainfall at odd times, disease outbreaks and the market shocks. Crop insurance is the only solution to mitigate these risks. Crop yield records are of great importance to predict the crop yield/area into a region but the developing countries like Pakistan, have limited availability of crop yield records. Crop Reporting Service (CRS) in Punjab province of Pakistan has taken this initiative to save crop related data. We obtained the CRS based datasets of rice crop from (2008-2018) to predict the rice yield/area for the fiscal year 2019. The CRS based datasets were incorporated in collaboration with remotely sensed dataset to obtain more accurate results. The spectral responses of rice crop were taken as input to compute NDVI/RVI values of each year. We applied linear regression to NDVI/RVI and the CRS based yield to generate regression equations for prediction of rice yield for the year 2019 which was computed as 2.09 (ton/ha). The area under rice cultivation was estimated using supervised classification that was 139616 hectors. The net rice production was estimated as 219797 tons. Spectral responses of rice crop canopy proved efficient to determine the net productions.

“…Removal of vegetation for construction of buildings, malls and plazas, is considered the main cause of rise in urban temperatures [9]. Urban transport adds a variety of pollutants in the atmosphere through tail pipe emissions which cause to block the reflected solar radiations, and finally result into urban heat island [2]. The removal of vegetal cover from urban areas cause the solar radiations to approach earth's surface directly which result to an abrupt increase in urban temperatures in comparison to its surroundings [2].…”

Urbanization has become a hot issue in context of environmental and socio-political scenarios which is addressed at every forum internationally. The mega cities are considered the main origin of socio-economic development which caused to emerge a number of issues like biodiversity, environmental degradation, resource consumption, implementation of law and order and provision of basic facilities to the general public. The area under investigation consists of Lahore, Gujranwala and Sheikhupura. The study site was bounded by 73-75 E longitudes and 31-33 N latitudes. We used Landsat satellite data to map Spatio-temporal variations in urban sprawl from 1990 to 2019 with a temporal window of 15 years. The Landsat data is free, highly reliable and considered as primary source. The classification results show that the total area of study site was site was 29355 km2 including 21933km2 were green index 4595 km2 was under human settlements and 2827 km2 was the waterbody in 1990. The classification of Landsat image of the year 2005 describes that area of human settlements was increased to 9366 km2, the volume of water body was reduced to 2111km2 and the vegetation was also degraded to 17878km2. Again, the urban area was computed using satellite imagery for the year 2019 which was 16105km2 in 2019. Kappa stat proved the accuracy of supervised classification what was around 87%. Remotely sensed datasets proved the reliability of Landsat satellite images for estimation of urban sprawl during last three decades.
