Abstract

Mangroves in Indonesia are increasingly degraded and converted, due to development of aquaculture, urban areas and agriculture. Because managers and decision makers are often ill-informed, we aimed to assess the consequences of management decisions in Java’s mangroves by studying the effect of different management regimes on ecosystem services. We developed a novel typology of mangrove management regimes, which distinguishes natural, low intensity use and high intensity use mangroves, and mangroves converted to aquaculture or abandoned aquaculture. The regimes considered legislation and were further characterized by local management indicators and quantified ecological characteristics. We furthermore compiled drivers, ecosystem properties, and state and performance indicators for the provision of seven key ecosystem services, such as coastal protection, nursery and carbon storage. By relating management regimes’ characteristics and ecosystem services indicators, we identified service provision per regime. These qualitative and quantitative outcomes were incorporated into a scoring system. Our results indicate that natural mangroves provide the most and highest amount of ecosystem services, whereas aquaculture artificially provides high amounts of fish and shrimp but at the cost of all other ecosystem services. Rehabilitation of aquaculture systems reverses this loss of ecosystem services, while still providing shrimp or raw materials. The management regimes represent clear management goals and are currently considered by decision makers. Interestingly, although decision makers had originally requested solely economic data, they later admitted that our ecology-grounded information proved more appropriate for developing sustainable management plans.
