Cost-Effectiveness Analysis of Coral Reef Management and Protection: A Case Study of the Republic of the Maldives

Cost-Effectiveness Analysis of Coral Reef Management and Protection: A Case Study of the Republic of the Maldives

Primary Country: Maldives
Ecosystem: coral reef
Sample Value Estimates:
(a) $900 million cost per unit coral reef rugosity for land use (b) $900 million cost per unit for tourism (c) $1,100 million per unit for all (d) greater than $6000 million per unit for sediment. These values show cost effectiveness of various environmental protection strategies for the Coral-Maldives coastal zone management decision support system, applied to North and South Male. They are rough estimates only intended as models. "Landuse" is protection of reefs through land use regulation; "Sediment" is reduction of sedimentation reaching the reefs; "Tourism" is restrictions for tourist resorts regarding building regulations and waste disposal; and "All" is a combination of all measures to improve the environment. The costs are the total discounted to 2005 dollar costs over the 10 year period.
Methodology: investment cost and maintenance cost and discounted to base year
Data source: The World Bank

Addtional Notes

The user definitions (scenarios, economic development and environmental protection options) drive the socio-economic model, which results in a set of impacts distributed over the area. The impacts are measured by sediment loading and levels of physical damage. These are then used as input into the ecological response model. The costs of the environmental protection options and the changes in the reef health are considered in the cost-effectiveness analysis which allows a ranking in terms of cost per unit change in reef health.
