The Costs of Obtaining Environmental Outcomes through Coastal Habitat Restoration

Abstract

Studies examining the costs of coastal habitat restoration have focused on the cost per acre of restoration or on cost efficiency of various restoration methods. On the other hand, studies examining the benefits of restoration have focused on various ecosystem services that more directly affect welfare including amenity value, storm protection, nutrient retention and biodiversity. We examine a set of 133 Gulf of Mexico coastal habitat restoration projects to estimate the cost of obtaining average annual habitat units (AAHUs), a measure which captures the quantity and, importantly, quality of habitat restored, which is one of the more direct ecosystem service benefits from coastal restoration. AAHUs are the environmental outcome considered during the assessment of proposed projects by decision-makers and therefore are a potential measurement unit that can more closely link costs and benefits of restoration.
