    Urbanization, driven by the population's basic needs and regional geography, can lead to uncontrolled expansion. Therefore, multicriteria geolocation is proposed as an effective tool to identify areas that promote sustainable urban development. The objective of the research was to propose sustainable urban soils based on multicriteria soil types, focusing on the selection of three cities in Junín (Chanchamayo, Tarma and Jauja), Peru. A multicriteria analysis was employed, integrating eight edaphological criteria and the Fuzzy Logit method to manage the uncertainties inherent in geospatial data and calculate fuzzy weights to estimate the probability of urban areas. The results indicated that predominant areas, such as alluvial cones, intrusive rock hills, and extensive vegetation cover, were considered possible zones for urbanization, suggesting that the weights assigned to urbanization varied according to the edaphological criteria and their sub-criteria. The city of Tarma demonstrated notable suitability for urbanization, with 14.54% of its territory showing a probability of urbanization of 0.9; in comparison, Chanchamayo achieved a suitability of 89.22% of its territory, with a probability of urbanization of 0.75, while Jauja stood out as the city with the lowest suitability for urbanization. The application of Fuzzy logistics revealed that the probability of suitability for urbanization in Tarma, Chanchamayo, and Jauja was related to the size of the areas, showing that larger zones had a higher probability of being suitable for urban development.

    Recovery of the Tambobamba Watershed after Environmental Zoning and Monitoring Using Vegetation Indices
    (International Journal of Environmental Science and Development, 2023-06) Solano Velarde, Zósimo; Quispe Reymundo, Bimael Justo; Révolo Acevedo, Ronald Héctor; Quispe Quezada, Uriel Rigoberto; Bonilla Mancilla, Humberto Dax; Quispe Quezada, Luthgardo Pastor
    Environmental zoning (EZ) in a watershed is intended to analyze the socioeconomic and biophysical parameters and design potential areas of intervention for the management and sustainability of natural resources, thereby improving people’s quality of life. EZ is incomplete without soil and water conservation techniques and management (SW/mct) to remediate natural environments. In this study, the Tambobamba watershed—during and after EZ—was analyzed in terms of socioeconomics, biophysics, and SW/mct, and monitored according to vegetation indices (VIs). To determine the socioeconomic situation, a rapid rural survey was conducted. To design biophysical maps, each area of the watershed was evaluated. The EZ was designed in 2018, under the demands and basic needs of the population. For monitoring in 2017, 2019, and 2021, the VIs were applied. Population density and poverty levels were low, economic activity was high, there was no university education, and basic services and communication routes were scarce. The watershed presented four climates, two natural domains, a glacial surface, six life zones, eight physiographic zones, two taxonomic orders of soils, and twelve geological classifications. The land is dominated by unused areas, the dominant slope was steep and had four types of HLCUs. Watershed remediation after S-W/mct showed that SAVI increased by 0.01, MSI increased by 0.8, EVI remained constant, NDWI increased by 0.06, and NDVI increased by 0.02. After performing the EZ, we affirmed that the Tambobamba watershed is in a slow recovery.
