The report assesses three intervention scenarios for the Pandarachirathodu Canal in Kochi, India, to combat degradation, pollution, and flooding. It finds that all three scenarios—ranging from a hybrid 'integrated wetland technology' (IWT) to a comprehensive biodiversity park—are investment worthy. While the highest net benefits (INR 325-331 million) are achieved by combining IWT with nature-based interventions like mangroves and floating wetlands, the highest benefit-to-cost ratio is found in the baseline IWT scenario, yielding INR 9.78 in net benefits for every INR 1 invested.
