An application of contingent choice modelling to assess environmental management options in the shrimp-mangrove system in the Indian Sundarbans

摘要

The Indian Sundarbans, in West Bengal, is inhabited by small-scale farmers and traditional paddy-cum-prawn cultivators; however, this unique region is also ideal for large-scale commercial shrimp aquaculture. Recent policy initiatives may facilitate expansion of commercial shrimp aquaculture in India, potentially setting the stage for conflict between different stakeholders in the Indian Sundarbans. This research project presents policymakers with an ex ante analysis of four alternative development scenarios, based on a more participatory approach to the decision making process. Using a contingent choice modelling methodology to quantify the preferences of local stakeholders for economic, social, and environmental attributes, policymakers and local stakeholders can measure and compare the preferences of local stakeholders for alternative management options. Local stakeholders, including shrimp fry collectors, shrimp farmers, and agricultural farmers, prefer a sustainable approach to development in the region, especially with respect to the management of mangrove forests, and access to alternative income generating opportunities.
