Ítem Agricultural eco-efficiency and water footprint- A case study of fifteen crops in the Chupaca province of Peru(ANSF. Applied Natural Science Fundation, 2023-12-20) Quispe Quezada, Uriel Rigoberto; Quispe Quezada, Luthgardo P.; Révolo Acevedo, Ronald H.; Solano Velarde, Zosimo; Álvarez Orellana, Julio; Jauregui Ofracio, Janette; Quispe Reymundo, Bimael J.The water footprint is an indicator of the impact of water use from its formation to its final destination. Agricultural eco-efficiency measures the efficient use of resources or materials available for crop production. Water's economic productivity analyses a product's efficient value as per its water supply and commercial value. The present research aimed to determine and relate the water footprint, economic productivity of water and agricultural eco-efficiency of 15 crops in the province of Chupaca - Peru. Georeferencing material was used for the delimitation of agricultural species, CROPWAT 8.0, CLIMWAT8.0, ArcGis 10.5 software, mathematical equations for the water footprint, agricultural eco-efficiency (Data Envelopment Analysis (DEA)) and economic productivity of water. The Total water footprint (TWF) of the fifteen crops was 1718237.01 m3/ton, likewise the BlueWF > GreenWF > GreyWF. In their economic outputs, gross value of production (GVP) > agricultural production (Ag-p) > economic rent agricultural (ERA) was verified. In environmental costs, water consumption that meets the needs of crops (Wc-Ag) > consumption of phytosanitary products (C-fly) > fertilizer consumption (C-fe) was determined. The average Agricultural eco-efficiency (Ag-Eec) and Economic water productivity (Ewp) were 89.8% and 0.046 PEN/m3 respectively. Statistical analysis between Ewp and Ag-Eec was rho = 0.18, t-test = 0.66 < 2.16 (α = 0.05; bilateral), and the correlation indicated that both activities are independent. The environmental costs and economic outputs of agricultural eco-efficiency did not influence the economic value of water.Ítem Analyzing solid waste landfills using satellite imagery and designing new landfill reception areas(ANSF. Applied Natural Science Fundation, 2023-06-20) Révolo Acevedo, Ronald H.; Quispe Reymundo, Bimael J.; Rodríguez Cerrón, Mauro; Quispe Quezada, Uriel Rigoberto; Quispe Quezada, Luthgardo P.; Solano Velarde, Zosimo; Paredes Atoche, VíctorSolid waste disposal is important for environmental management for good quality of life in urban cities. Among them is the final disposal of waste in landfills. Landfills can receive tons of waste, but they must be far away from natural resources and urban areas. The research aimed to analyze the physical and biological conditions and design a geolocation map of new sanitary landfills in three urban cities in Peru (Chilca, El Tambo and Huancayo). Landsat 8 OLI/TIRS satellite imagery was used to analyze the physical (LST and Methane) and biological (NDVI and SAVI) conditions of the landfills. The geolocation of the landfills was analyzed through the relationship, intersection and discrimination between their surface criteria (soil type, current use, geology and physiography) and climatic factors (temperature, humidity and precipitation). The physical and biological conditions of the landfills were: CH4: Chilca 8.33g > Huancayo 4.76g > El-Tambo 3.17g; SAVI: Chilca 0.61 > El Tambo 0.54 > Huancayo 0.51; LST: Huancayo 26.15°C > Chilca 24.03°C > El Tambo 22.75°C; NDVI: Chilca 0.85 > Huancayo 0.81 > El Tambo 0.8. In the three cities, "natural grasslands" were considered suitable land for the new solid waste landfill site. The multiple relationship, intersection, and discrimination of surface criteria and climatic factors were categorized into five types of sustainable geolocation (very appropriate > appropriate > moderately adequate > less appropriate > inappropriate) for new solid waste landfills. It was very important to discount the influence areas (rivers and lagoons) to avoid damaging the natural resources.Ítem Multicriteria geolocation for new urban areas: A case study in three cities of Peru(ANSF. Applied Natural Science Fundation, 2025-12-20) Solano Acuña, Vreni Renán; Solano Velarde, Zosimo; Révolo Acevedo, Ronald Héctor; Quispe Reymundo, Bimael Justo; Castro Blancas, Medaly C.; Bonilla Mancilla, Humberto D.; Quispe Quezada, Uriel Rigoberto; Quispe Quezada Luthgardo PastorUrbanization, 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.
