As per the latest survey produced by the Forest Survey, the forest cover is 19.27% of the geographic area. According to this report every country can meet the human needs of 16% of the world’s population from the 1% of the world’s forest resource. The Forest Survey said that 90% of the forest fires created by humans. They pose a threat not only to the forest wealth but also this leads to the main threat to biodiversity, a change in the ecosystem. The environment gets dry and twinges, which leads to produce flames in the forest. There are two types of forest fire i) Surface Fire and ii) Crown Fire iii) Ground Fire. Surface Fire: The forest fire starts its flame primarily as a surface fire, spreading along the ground with the help of dry grasses and so on. Crown Fire: It starts flame on the crown of the shrubs, bushes and trees and sustained on the surface. This type of fire is very da...

Forest fires are one of the main problems that affect biodiversity and forest heterogeneity, which are caused by human or natural activities and even driven by climate change. The objective of this study was to analyze the severity of forest fires with the NBR index (Normalized Burn Ratio) in highland areas of Peru, and evaluate the vegetative recovery of forest species in the affected area with the NDVI index (Normalized Difference Vegetation Index). As a result, it was obtained that the type of vegetation in the affected area is the Andean Pajonal, the level of severity in the study area ranges from low to moderately high, with low severity being the predominant one, which occupies 57,562% of the study area. The NDVI evaluation of 2 weeks before, 2 weeks after and 3 months after the event show that there is a vegetative regeneration of the vegetation cover, two weeks after the event in...

Forest fires are a potential threat to life, as they contribute to reducing forest areas, impact on the services we expect from ecosystems, the health of the inhabitants is affected by smoke and the economic costs for the recovery of affected areas is high. The objective of the study is to apply fuzzy logic to model the risk of forest fires in the Cajamarca-Peru region, incorporating variables that represent biological, topographic, socioeconomic, and meteorological factors. The analysis was based on the acquisition, editing and rasterization of the database, application of fuzzy membership functions and image fuzzification, fuzzy superposition and spatial reclassification of forest fire risk. The results obtained show that 71.68% of the area is under very low or medium forest fire risk. However, 28.32% of the study area has a high to very high fire risk, which makes the occurrence of fi...

Fire is an important element in the development of ecosystems, however when it is spread out of control in areas such as forests and woodlands, the negative effects to the environment and ecosystems are considerable. The Natural Protected Area of Flora and Fauna of Maderas del Carmen (ANPFFMC) is no exception, so the main objective of this work was mapping the rate of forest fuel from the forest of conifers of the ANPFFMC, through the estimation of dead fuels and the burden of the organic layer. 22 conglomerates were sampled, the vegetation was delimited through the classification of a Landsat-8 satellite image. The results allowed mapping the rate of risk of forest fire through the statistical interpolation method “spline with barriers” generating a barrier of the supervised image interpolation. The average values obtained for 1 hour fuels were 1.22 t-ha-1, to 5.24 hours t-ha-1, for...

The use of fire in agriculture has been a fundamental practice since early human societies, playing a key role in land preparation, weed control, and soil fertility management. In the Peruvian Andes, fire remains widely employed by rural communities, despite strict legal prohibitions aimed at reducing wildfire occurrence. However, statistical evidence demonstrates that these punitive policies have failed to curb wildfires, which have instead increased in frequency. This study critically examines the agricultural use of fire in high Andean communities of Cusco, Peru, exploring its socio-cultural, economic, and environmental dimensions. Through ethnographic research and qualitative methodologies, the study identifies the motivations behind fire use, traditional fire-management practices, local and institutional perceptions, and community responses to wildfires. Findings reveal that fire is...

Dry forests are home to large amounts of biodiversity, are providers of ecosystem services, and control the advance of deserts. However, globally, these ecosystems are being threatened by various factors such as climate change, deforestation, and land use and land cover (LULC). The objective of this study was to identify the dynamics of LULC changes and the factors associated with the transformations of the dry forest in the Tumbes region (Peru) using Google Earth Engine (GEE). For this, the annual collection of Sentinel 2 (S2) satellite images of 2017 and 2021 was analyzed. Six types of LULC were identified, namely urban area (AU), agricultural land (AL), land without or with little vegetation (LW), water body (WB), dense dry forest (DDF), and open dry forest (ODF). Subsequently, we applied the Random Forest (RF) method for the classification. LULC maps reported accuracies greater than ...

In Peru, grasslands monitoring is essential to support public policies related to the identification, recovery and management of livestock systems. In this study, therefore, we evaluated the spatial dynamics of grasslands in Pomacochas and Ventilla micro-watersheds (Amazonas, NW Peru). To do this, we used Landsat 5, 7 and 8 images and vegetation indices (normalized difference vegetation index (NDVI), enhanced vegetation index (EVI) and soil adjusted vegetation index (SAVI). The data were processed in Google Earth Engine (GEE) platform for 1990, 2000, 2010 and 2020 through random forest (RF) classification reaching accuracies above 85%. The application of RF in GEE allowed surface mapping of grasslands with pressures higher than 85%. Interestingly, our results reported the increase of grasslands in both Pomacochas (from 2457.03 ha to 3659.37 ha) and Ventilla (from 1932.38 ha to 4056.26 ha...

Dry forests are ecosystems of great importance worldwide, but in recent decades they have been affected by climate change and changes in land use. In this study, we evaluated land use and land cover changes (LULC) in dry forests in Peru between 2017 and 2021 using Sentinel-2 images, and cloud processing with Machine Learning (ML) models. The results reported a mapping with accuracies above 85% with an increase in bare soil, urban areas and open dry forest, and reduction in the area of crops and dense dry forest. Protected natural areas lost 2.47% of their conserved surface area and the areas with the greatest degree of land use impact are located in the center and north of the study area. The study provides information that can help in the management of dry forests in northern Peru.

The threat of large forest fires is increasing, and the main causes are the depopulation of rural areas, along with the effects of climate change. To counter this threat in recent decades, there have been numerous proposals and actions aimed at promoting grazing in the forest as a tool for controlling biomass fuel. However, the continued disappearance of traditional herds makes this activity difficult. Rural depopulation has also meant that domestic species become feral, being habitual in the case of goats. Currently, little is known about the role that feral goats can play in the fight against forest fires. In this work, an analysis is made on the effect of feral goats on the control of the vegetation in firebreak areas. Furthermore, the effect of attractants, such as water, salt, or food, on goat behavior is also studied. The study was carried out on the island of Mallorca, where a pop...
