Developing payment for ecosystem service schemes for coastal aquaculture in southwestern Taiwan

Abstract

Taiwan’s aquaculture farms are mostly established along intertidal zones and coastal land areas, and their presence may affect coastal ecosystems and their ecosystem services (ESs). Payments for ecosystem services (PES) represent a potential method of enhancing the provision of ESs for coastal aquaculture; thus, their feasibility should be discussed. In this study, we conducted focus group interviews to identify issues and collect information about coastal aquaculture in southwestern Taiwan, and we developed a PES framework for coastal aquaculture based on our findings. The identification of ESs and the inclusion of a market design (e.g. pricing, incentive, and conditionality) in a PES scheme might be key factors for successfully transforming aquaculture into an ES provider. PES schemes could be applied to coastal oyster farming in Taiwan, and coastal oyster farmers who adopt eco-friendly aquaculture should receive subsidies to secure revenues. The findings presented here will provide important reference information for policy makers and managers to design a feasible PES scheme for coastal resource management.

Planning and licensing for marine aquaculture

“…142 Some studies have suggested that seaweed could be grown at large scale and then sunk to the deep sea to temporarily lock carbon away from the surface, 193 but there are many uncertainties within this approach and more research is required. 142 A range of schemes have been suggested for payment for ecosystem services (PES), [195][196][197] although valuation of ecosystem services is not always financially focused. 198 Nevertheless, of particular interest to many in aquaculture is the use of certified credit schemes, where organisations purchase credits from the aquaculture producers to compensate for, or offset, their own emissions or environmental impacts, whether they are nutrients or carbon.…”
