“…According to empirical observations, Ross (1994) assigned weights to different natural parameters, such as slope, type of vegetation, occupation of the site, and soil orders, and used simple algebra to generate a value that functions as an environmental fragility score. According to each case, other authors have widely reused this method with different parameters and equations [26][27][28][29][30][31]. Here, the model proposal was adapted to create productive potential scores.…”

Understanding a crop’s productive potential is crucial for optimizing resource use in agriculture, encouraging sustainable practices, and effectively planning planting and preservation efforts. Achieving precise and tailored management strategies is equally important. However, this task is particularly challenging in coffee cultivation due to the absence of accurate productivity maps for this crop. In this article, we created a multicriteria model to estimate the productive potential of coffee trees based on the observation of landscape elements that determine environmental fragility (EF). The model input parameters were slope and terrain shape data, slope flow power, and orbital image data (Landsat 8), allowing us to calculate the NDVI vegetation index. We applied the model developed to coffee trees planted in Bambuí, Minas Gerais, Brazil. We used seven plots to which we had access to yield data in a recent historical series. We compared the productivity levels predicted by the EF model and the historical productivity data of the coffee areas for the years 2016, 2018, and 2020. The model showed a high correlation between the calculated potential and the annual productivity. We noticed a strong correlation (R2) in the regression analyses conducted between the predicted productive potential and the actual productivity in 2018 and 2020 (0.91 and 0.93, respectively), although the correlation was somewhat weaker in 2016 (0.85). We conclude that our model could satisfactorily estimate the yearly production potential under a zero-harvest system in the study area.

Demographic expansion and intensive human activities have negatively impacted natural landscapes worldwide. The conversion of natural areas into anthropogenic sites often occurs without adequate planning, resulting in severe environmental and social problems. There is a constant search for the development of diagnosis and environmental planning methodologies to analyze the landscape in an integrated way. Geographic Information Systems (GIS) and the cartographic representation of different landscape attributes (i.e., soil types, rainfall regime, topography, land use/land cover, among others) are essential tools for understanding the environmental dynamics of a region. This study focuses on analyzing environmental fragility in areas near the reservoir of the Jurumirin Hydropower Plant in the state of São Paulo, Brazil, using a fuzzy logic-based approach and spatially continuous data. The results indicate a medium and high environmental fragility predominance, significantly influencing agricultural practices and land use. The fuzzy approach allowed for a more precise representation of transitions between fragility classes, enhancing the understanding complex interactions among landscape attributes. These findings significantly impact reservoir management and environmental decision-making in transformed landscapes.

“…The management and monitoring of land use and occupation through Geographic Information Systems (GIS) has been gaining ground as an auxiliary tool for understanding the rapid changes in the landscape, since it allows obtaining information for the construction of scenarios and environmental indicators, that can be used as practical subsidies in the assessment of environmental support capacity (OLIVEIRA-ANDREOLI et al, 2021).…”
