There is an information gap on biodiversity effects of land use and land cover (LULC) dynamics of agrarian landscapes. Such data are essential for policy making and species management in agro-ecosystems. Thus, changes in LULC inside the Abohar wildlife sanctuary and its eco-sensitive zone were investigated using LISS-III satellite images from 2003 to 2016. The area under cropland witnessed a 3.6% increase, whereas wastelands significantly declined by 4.3%. Further, the impact of LULC dynamics on nilgai (Boselaphus tragocamelus) was determined through mortality distribution in the sanctuary from 2012 to 2017. The spatio-temporal distribution pattern of mortality revealed that a total of 336 nilgai died during the six years studied. Free-ranging feral dogs, in conjunction with fencing and road accidents, were the major factors involved in nilgai casualty. Fatalities were clustered in regions with significant LULC change. The results confirmed that intensified development and reuse of derelict agricultural fields disturbed nilgai ecology and habitat use pattern. Human-wildlife conflicts in agrarian landscapes are an increasing concern and should be managed following identification of sensitive areas.

农业土地利用和土地覆盖做法对印度西北部阿伯哈尔野生动物保护区及其周围的尼尔基羚羊(Boselaphus tragocamelus)生存和保护的影响

关于土地利用和土地覆盖(LULC)动态的生物多样性影响存在信息鸿沟。这些数据对于农业生态系统中的政策制定和物种管理至关重要。因此,使用LISS-III卫星图像从2003年至2016年调查了阿伯哈尔野生动植物保护区及其生态敏感区的土地利用,土地利用变化。耕地面积增加了3.6%,而荒地则减少了4.3%。此外,LULC动力学对尼尔基Boselaphus tragocamelus)是通过2012年至2017年该保护区的死亡率分布确定的。死亡率的时空分布模式表明,在研究的六年中,共有336例尼尔基人死亡。自由放养的野狗,加上击剑和道路交通事故,是造成尼尔盖族伤亡的主要因素。死亡人数集中在LULC变化显着的地区。结果证实,废弃农业的集约化和再利用加剧了尼尔盖河的生态和生境利用方式。耕地景观中的人与野生动物冲突日益引起人们的关注,应在确定敏感地区后加以处理。
