This study focuses on exploring spatio-temporal changes in land use and land cover over Bandipora district of Jammu and Kashmir, India. There is significant decreases in agriculture, dense forest, and water body over the region with positive changes in the built-up area, aquatic vegetation, horticulture, marshy land, pasture, plantation, and sparse forest. It is interesting to note that Asia’s largest fresh water lake “Wular” which has witnessed a large scale change in its ecosystem falls in the study area. Land use and land cover maps were explored using on screen digitisation generated from series of Landsat data (1979, 2001 and 2018). Environmental parameters like precipitation (both rain and snowfall), temperature and black carbon were analysed in order to relate with land-use and land-cover changes in the study area. Results report decreases of about 23%, 25%, 12%, 60% in agriculture, dense forest, scrub, water body, respectively from 1979 to 2018 in the study area

Furthermore, increases of about 59%, 58%, 254%, 17% are reported in horticulture, sparse forest, built up and aquatic vegetation, respectively. Decrease in agriculture is attributed to decreased precipitation over study area. A decadal decrease of about 0.5% in precipitation is reported in the study area. Increased horticulture and dependency of population over forest significantly resulted in increased black carbon. This study reports a decadal increase of about 2.2% nm in black carbon in the study area. Reduction in precipitation affected Wular lake by shrinking its fresh water coverage. The fresh water area of the lake is decreased by 75% during 1979 to 2018. As one of the source of water for lake is precipitation in the form of (rain and snow), significant reduction in fresh water of Wular lake poses significant socio-economic impact on the population of study area. Present study highlights the importance of effective government policies for mitigating the impact of significant land use and land cover changes over Bandipora district.

印度北部地区土地利用土地覆盖变化的时空格局及其对环境和社会的影响

本研究的重点是探索印度查谟和克什米尔邦迪波拉地区土地利用和土地覆盖的时空变化。全区农业、密林、水体明显减少,建成区、水生植被、园艺、沼泽地、牧场、人工林、疏林发生积极变化。值得一提的是,亚洲最大的淡水湖“乌拉尔”,其生态系统发生了大规模的变化,落入了研究区。使用从一系列 Landsat 数据(1979、2001 和 2018 年)生成的屏幕数字化来探索土地利用和土地覆盖图。分析了降水(降雨和降雪)、温度和黑碳等环境参数,以便与研究区的土地利用和土地覆盖变化相关联。

此外,据报道,园艺、疏林、人工建造和水生植被分别增加了约 59%、58%、254%、17%。农业的减少归因于研究区域的降水减少。据报道,研究区的降水十年间减少了约 0.5%。园艺业的增加和人口对森林的依赖显着导致黑碳增加。该研究报告称,研究区域的黑碳在十年间增加了约 2.2% nm。降水的减少影响了乌拉尔湖的淡水覆盖面。1979 年至 2018 年,湖泊淡水面积减少了 75%。由于湖泊的水源之一是(雨和雪)形式的降水,乌拉尔湖淡水的显着减少对研究区人口造成了重大的社会经济影响。目前的研究强调了有效的政府政策对于减轻班迪波拉地区重大土地利用和土地覆盖变化的影响的重要性。
