River Restoration and Urban Revitalization in Los Olivos, Lima - Peru

Abstract

Rapid urbanization, inadequate infrastructure, and climate change place communities such as Los Olivos at risk during cyclical flooding. River floods can disrupt a community by damaging infrastructure, housing, access to potable water and transport. Resilience strategies and river defenses for disaster risk reduction need to be implemented in vulnerable areas. The risk factors related to poor infrastructure and planning, poor waste management, and riverfront development must be addressed. A case study methodology provides means to analyze three successful projects to gather possible solutions from different perspectives and realities. For flood protection, gabions, soft green and blue infrastructure system that protects the riverbed from erosion are sustainable, low impact, and easy to maintain. For revitalization, the key is to increase the quality of life. Finally, regarding urban design, the implementation of green areas and street furnishings improves the quality of space, leading to a more cohesive community. The most appropriate solutions identified are applied in the study area in the Los Olivos district in Lima, Peru.
