Item Urban Green Space And Question Of Distributive Justice: A Study Of Cities Of Punjab Using Geo-Spatial Approach(Central University of Punjab, 2018) Kaur, Navjotpreet; Singh, Kiran K.Urban green parks play vital role in providing fresh and healthy environment in urban areas. But conspicuous problem remains in unequal distribution of parks. This problem raises various questions. One of them is distributive justice. This study was conducted for four major cities of Punjab: Ludhiana, Bathinda, Amritsar and Chandigarh, to check the location of parks and slums in these cities to look into the problem of distributive justice. In study, the buffer analysis is used to know the serving area of parks and to represent over-served, served and un-served area of parks. GIS (Geographical Information System) is used to derive the serving area of parks. The result shows that major concentration of parks is in exclusive areas in these cities like elite class residential localities. It also highlights that most of the parks are far away from the slum areas. The study also shows that well planned areas have the high facility of parks than others. Overall, these findings help in underscoring the problem of distributive justice in allocating parks in urban areas.Item Mapping of Surface Water Bodies in Punjab and High Resolution of Remote Sensing Data(Central University of Punjab, 2018) Ahmed, Mukhtar; Singh, Kiran K.This study is an attempt to create boundary of Punjab state and surface water bodies map from NATMO atlas map, SOI map, Landsat-8 data and Google Earth image using GIS software. It has also compared the variation in status which is extracted from the data or image of various scale or resolution. According to NATMO data, the water bodies in Punjab are 1476. 109km2 (excluding canals), according to Landsat-8 are 2844.55 km2 (including canals), according to SOI are 764.93 km2 and according to Google earth are 141.06 km2. Variation in the status of the area and length of surface water bodies is due to the scale and resolution of images. High resolution image is capable of creating precise boundaries. The purpose of this study was to create precise boundaries of the state and water bodies. Management of water bodies calls for generation of multiple inventories and demarcation of precise boundary is one of the inventories. This study also suggests the Map making organisations to revise their maps by using recent geospatial technologies.Item Isolation of indigenous butachlor (Herbicide) degrading bacteria from the agricultural fields of punjab(Central University of Punjab, 2014) Singh, Jatinder; Yogalakshmi, K.N.Butachlor (N-Butoxymethyl-2-chloro-2', 6'-diethyl acetanilide) is a chloroacetalanilide herbicide widely used in paddy fields. Due to extensive application, high stability and persistence in soil and water, has resulted in its ubiquitous presence as a pollutant. Hence, it becomes necessary to degrade the herbicide through an eco friendly and cost effective method. In this study, the degradation of butachlor herbicide was studied under controlled laboratory condition. The soil was collected from the agricultural fields of Punjab. The inoculum from the soil was enriched in 0.16mmol/L of butachlor at 130 rpm and 30 ?C. The enriched culture was plated and the best growing bacteria was isolated and designated as JF. The biodegradation of strain JF was evaluated at 0.16 and 0.32mmol/L concentration of butachlor. The isolate showed a degradation efficiency of 91.87% and 78.08% at 0.16mmol/L and 0.32mmol/L of butachlor, respectively in 120 hours (pH 7). The bacterial isolate JF was identified as Staphylococcus sp. through biochemical characterization. This study highlights the first report of isolation of butachlor degrading bacteria from the native soil of Punjab.
