Green Corridor Along the Chili River as an Ecosystem-Based Strategy for Social Connectivity and Ecological Resilience in Arequipa, Arequipa, Peru, 2025

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.
