In recent decades, accelerated urban growth in Arequipa has led to the loss of more than 40% of riparian vegetation and increased ecological fragmentation in the Chili River valley. This transformation has degraded water quality and limited equitable access to green and public spaces. Therefore, this research aims to design a Green Corridor along the Chili River as an ecosystem-based strategy to enhance social connectivity and ecological resilience in Arequipa, Peru. The methodology combined an extensive literature review, a comparative analysis of international case studies, and a territorial diagnosis supported by geospatial and climatic data. The process is supported by digital tools such as Google Earth Pro 2025, AutoCAD 2024, SketchUp Pro 2023, and solar simulations with Ladybug-Grasshopper, complemented by data from SENAMHI, SINIA, and the Solar Atlas of Peru. The results propose a resilient green corridor integrating passive and active sustainability strategies, including 40 photovoltaic panels, 44 solar luminaires, biodigesters producing between 90 and 150 kWh per month, and phytotechnologies capable of absorbing 75,225 kg of CO₂ annually, based on WHO conversion factors adapted to high-altitude conditions. The proposal employs eco-efficient materials such as reforested eucalyptus wood and volcanic sillar, creating recreational and productive spaces that promote social cohesion and circular economy. In conclusion, this study demonstrates the potential of ecosystem-based design to regenerate arid urban riverbanks, harmonizing environmental sustainability, social inclusion, and cultural identity. Thus, the Chili River corridor is consolidated as a replicable model of green-blue infrastructure for Andean cities, aligned with Sustainable Development Goals 6, 7, 11, 12, 13, and 15.

Limited accessibility, mountainous geography, and seismic conditions have posed challenges to both the preservation and the transmission of knowledge inherited from the Incas. Therefore, this research aims to analyze the ancestral Inca construction systems and their relationship with the Inca worldview through an architectural and structural study of the archaeological site of Choquequirao, located in Cusco, Peru. The research integrates geographic, climatic, spatial, functional, and constructive dimensions, applying digital 3D modeling tools (AutoCAD 2025, SketchUp 2024, and Sun-Path 2024) to assess the orientation, stability, and symbolic configuration of the main sectors. The results of the functional and constructive analysis reveal that Choquequirao incorporates adaptive principles in response to seismic and microclimatic conditions, as well as constructive typologies planned from an integral architectural perspective. These elements allow a clearer understanding of the spatial organization of the site and its cultural significance. Moreover, the study covers ten sectors distributed across 1800 hectares. The upper sector (4 ha) stands out for its architecture and political–ceremonial function; the lower sector (4 ha) includes ritual, administrative, residential, and storage areas for camelids; the southern sector (5 ha) contains the ushnu and priestly enclosures on terraces; and the eastern (7 ha) and western (2 ha) slopes integrate agricultural and residential uses. The study of Choquequirao highlights its complex organization and addresses contemporary challenges in terms of conservation and development. These findings provide essential insights for future restoration and conservation strategies that respect traditional construction systems and their environmental adaptation.
