Rapid Assessment Protocol: Urban Risks to Biodiversity in Amazonian Cities - Iquitos, Peru

Deforestation of the Peruvian Amazon–the largest portion of the Amazon rainforest after Brazil–has risen alarmingly in the past decade, with Global Forest Watch reporting the country has lost at least 5% of its total tree canopy since 2002. This rapid forest loss threatens one of the world's most biodiverse ecoregions and pushes vital natural carbon sinks closer to an ecological tipping point. While large-scale agricultural and extractive activities are well-documented drivers of forest loss, the rapid, unplanned, and highly informal urbanization of Amazonian cities exerts severe, less-evaluated pressures on surrounding ecosystems. As subnational actors increasingly lead local climate mitigation and adaptation strategies, cities in critical ecoregions require immediate, actionable tools to monitor urban growth impacts and protect regional biological assets.  

To address these challenges, the MIT Environmental Research and Action Labs (ERA), in collaboration with the Universidad de Ingeniería y Tecnología (UTEC), is developing a "Rapid Assessment Protocol for Urban Risks to Biodiversity" centered on the case study of Iquitos, Peru. Located in the province of Loreto, Iquitos is the second-largest city in the Amazon and remains uniquely isolated from road infrastructure, positioning it as an ideal landscape for testing community-based environmental planning alongside innovative monitoring tools.  

The project aims to develop a replicable framework structured around four core components: conducting a comprehensive assessment of urban stressors on biodiversity and associated indicators, mapping technological and participatory data collection strategies and data sources, facilitating direct stakeholder and community engagement, and conceptualizing the rapid assessment framework. By merging academic scholarship with place-based, participatory planning, the collaboration seeks to deepen global understandings of tropical urban biodiversity stressors, leverage local data collection capacities, and inform global climate goals tied to safeguarding critical natural ecosystems.

Understanding Urban Stressors in Amazonian Cities 

The initial phase of the project focuses on establishing a grounded, global literature review and conducting stakeholder interviews to identify and prioritize the primary stressors that Amazonian cities impose on biodiversity. Through this comprehensive literature review, we identified a robust matrix of potential urban biodiversity indicators tailored to tropical contexts. The identification of these indicators marks a vital milestone in establishing measurable baselines for urban stressors like impervious surfaces, informal settlement encroachment, and localized habitat fragmentation, among others.
