Vertical Green Infrastructure and Biophilic Design as Key Factors in Urban Sustainability: Environmental Regulation Proposal in Cajamarca 2025 - Peru

Abstract

The project analyzes how vertical green infrastructure (green walls, green roofs, rain gardens) and biophilic design (integration of natural elements into buildings) can improve urban sustainability in Cajamarca, a city facing problems such as increased PM2.5, disorderly urban growth, loss of green areas, and a progressive disconnect between the population and nature. A municipal regulation is proposed that establishes minimum requirements for vegetation on facades and roofs, rainwater harvesting systems, mandatory maintenance, separation of networks, and natural ventilation and lighting strategies. Incentives such as reduced municipal taxes and certifications are also proposed to promote the adoption of these practices. The methodology combines documentary analysis, urban- environmental diagnosis, interviews, and regulatory review. The results indicate that the proposal is viable and can generate significant environmental and social benefits; however, it requires institutional strengthening, financing, adequate maintenance, and public awareness. Overall, the project constitutes a path to making Cajamarca a healthier, more resilient, and more ecological city, in line with SDGs 11 and 13 and with the Regional Environmental Policy for 2030.
