Globally, desertification is a challenging issue today. As per United Nations Convention to Combat Desertification (UNCCD), it has been altering the quality of life of several people across the world. The study deals with temporal monitoring and mapping land degradation and desertification over the Thar Desert, which occupies the northwestern part of Rajasthan, India, with arid climatic conditions. It is necessary to control desertification by taking a few safety steps to create an early warning system based on scientific facts and satellite and secondary data. The current study has focused on integrating different data (i.e., climate, vegetation, and socio-economic), primary and secondary, as per their availability at a spatial scale for evaluating Environmentally Sensitive Areas (ESA), prone to desertification. It also provides temporal observation of various ESA indicators to measure the intensity and severity of land degradation in desertification. The weightage of ESA indicators was assigned based on Analytical Hierarchical Processes (AHP) to quantifying the Environmental Sensitivity Index (ESI). Overall, current research can guide authorities in proceeding with appropriate measures for addressing the process of land degradation. It would help the concerned authorities to execute suitable actions for combating desertification as apprised in COP-14 meeting under UNCCD framework, lately held in New Delhi (India) in 2019.

在全球范围内，荒漠化是当今一个具有挑战性的问题。根据联合国防治荒漠化公约（UNCCD），它一直在改变世界各地许多人的生活质量。该研究涉及位于印度拉贾斯坦邦西北部、气候条件干旱的塔尔沙漠的土地退化和荒漠化的时间监测和绘图。有必要通过采取一些安全措施来控制荒漠化，以创建基于科学事实和卫星和二手数据的预警系统。当前的研究侧重于整合不同的数据（即气候、植被和社会经济），主要和次要数据，根据它们在空间尺度上的可用性来评估环境敏感区域(ESA)，容易发生荒漠化。它还提供对各种欧空局指标的时间观察，以衡量荒漠化土地退化的强度和严重程度。ESA 指标的权重是根据层次分析法 (AHP) 分配的，以量化环境敏感性指数(ESI)。总体而言，当前的研究可以指导当局采取适当措施来解决土地退化过程。正如最近于 2019 年在新德里（印度）举行的《荒漠化公约》框架下的 COP-14 会议所通报的那样，这将有助于有关当局采取适当的行动来防治荒漠化。
