Engineering vs. Ecosystems: Evaluating Climate Adaptation Approaches


This report sets out to answer the question – when it comes to climate adaptation, are engineering-based solutions (e.g., sea walls) more effective and economical than ecosystem-based approaches (e.g., coastal revegetation)?

I first look at the environmental drivers of adaptation, current international efforts, and dive into a case study of a town in the Fiji Islands that’s specifically wrestled with these competing approaches to adaptation.

The goal of this work is to help institutions like the U.N. Adaptation Fund and Green Climate Fund prioritize which adaptation approaches have been most successful to inform their financing decisions as the world has little time to plan for how they will brace for the inevitable environmental impacts of a 1.5 to 2C rise.
