The Cerrado is considered the most biodiverse savanna in the world, as well as the second largest Brazilian Biome. In recent decades, primarily due to agricultural expansion and wildfires, this biome has been severely degraded, losing nearly 50% of its original vegetation. This study aims to evaluate the degradation dynamics of the Cerrado vegetation as a function of human activity and climate variability. Products related to vegetation index (MOD13Q1) and an imaging spectroradiometer with moderate resolution from 2001 to 2018 were used to calculate the vegetation degradation index (VDI), which considers the vegetation cover as a function of human actions (deforestation, forest fires, agriculture, and farming). Rain and air temperature data were obtained from the Conventional Weather Station of Januária-Minas Gerais. Fire foci data were calculated using the moderate resolution imaging spectroradiometer - MODIS MCD14DL product sensor (TERRA/AQUA). Specifically, this study focused on the degradation of the vegetation in the Pandeiros River EPA (environmental protection area) that has increased due to the variability of climatic conditions, forest fires, and agricultural activities. The dry season provided greater sensitivity for the evaluation of the vegetation degradation process of the Pandeiros River EPA. The negative effects observed from the variation of climatic conditions and anthropogenic actions on the vegetation dynamics of the Pandeiros River EPA demand greater attention from administrative bodies on strategies for the conservation, preservation, and management of natural resources of conservation areas.

塞拉多被认为是世界上生物多样性最大的稀树草原，也是巴西第二大生物群落。近几十年来，主要由于农业扩张和野火，该生物群落已经严重退化，丧失了近50％的原始植被。这项研究旨在评估塞拉多植被的退化动态与人类活动和气候变化之间的关系。使用植被指数（MOD13Q1）和分辨率从2001年至2018年的中等分辨率的成像光谱仪的产品来计算植被退化指数（VDI），该指数将植被覆盖率视为人类活动（森林砍伐，森林火灾，农业，和农业）。雨和气温数据是从Januária-MinasGerais的常规气象站获得的。使用中分辨率成像分光光度计-MODIS MCD14DL产品传感器（TERRA / AQUA）计算了火灾数据。具体而言，这项研究的重点是Pandeiros河EPA（环境保护区）中植被的退化，该退化由于气候条件，森林火灾和农业活动的变化而加剧。干旱季节为Pandeiros河EPA的植被退化过程评估提供了更高的敏感性。气候变化和人为活动对潘迪罗斯河EPA植被动态的负面影响要求管理机构更加重视保护区自然资源的保护，保存和管理策略。
