Pakistan has a limited forest coverage, with a significant portion, approximately 40%, concentrated in the Khyber Pakhtunkhwa (KP) region. This highlights the regional significance of KP in terms of forest wealth within the country. The substantial utilization and excessive exploitation of forests have negatively affected the ecosystems. This study aimed to focus on the environmental and social variables and their contribution to the onset of forest fires in KP using Maximum Entropy Model (Maxent). MODIS active fire data history from 2000 to 2022 was studied to establish the relation between forest fire likelihood and environmental conditions. The variables under study included raster data of temperature, wind, precipitation, elevation, slope, aspect, and population density with 2.5-min resolution accessed from Worldclim. The area under curve (AUC) fire probability value was determined to be 0.833, suggesting strong performance of the model. The jackknife analysis indicated the highest contribution of wind (34.2%) followed by precipitation (33.7%) and temperature (18.9%). Maxent was also used to study the potential fire risk zones. It was observed that 53% of the study area is under high-risk, 12% under moderate-risk, and 35% under low-risk. High-risk areas include Abbottabad, Mansehra, Battagram, Shangla, and some parts of Buner and Haripur. These results can prove to be helpful insight in developing preventive strategies for more focused fire management plans that can help reduce fire risk by considering environmental and socioeconomic conditions.
巴基斯坦的森林覆盖率有限,其中很大一部分(约40%)集中在开伯尔-普赫图赫瓦省(KP)地区。这凸显了KP省在该国森林资源方面的区域重要性。森林的大量利用和过度开发对生态系统产生了负面影响。本研究旨在利用最大熵模型(Maxent),聚焦于环境和社会变量及其对KP省森林火灾发生的影响。研究了2000年至2022年的MODIS有源火灾数据历史,以建立森林火灾可能性与环境条件之间的关系。所研究的变量包括从Worldclim获取的分辨率为2.5分钟的温度、风、降水、海拔、坡度、坡向和人口密度的栅格数据。曲线下面积(AUC)火灾概率值确定为0.833,表明该模型性能良好。刀切法分析表明,风的贡献最大(34.2%),其次是降水(33.7%)和温度(18.9%)。Maxent还用于研究潜在的火灾风险区域。观察到,研究区域的53%处于高风险,12%处于中度风险,35%处于低风险。高风险地区包括阿伯塔巴德、曼塞赫拉、巴塔格拉姆、尚拉以及布内尔和哈里普尔的一些地区。这些结果有助于深入了解制定更有针对性的火灾管理计划的预防策略,通过考虑环境和社会经济条件来帮助降低火灾风险。
