Abstract

This chapter highlights the relevance of autochthonous vs. allochthonous contributions to 'Blue Carbon' storage in mangrove sediments. Mangrove ecosystems have gained major attention in the scientific community and the public in recent years, because they are considered a major natural carbon sink. However, uncertainties on the magnitude of this sink and the underlying processes are still large. A unique feature of mangrove ecosystems is their ability to store not only internally produced organic matter, but also to store carbon derived from external sources. In the context of balancing anthropogenic CO2 emissions it is of relevance to know whether the carbon stored is autochthonous, i.e. derived from the recent fixation of CO2 in the mangrove ecosystems, or it is allochthonous, i.e. relocated and possibly old carbon from other reservoirs. The relevance of these aspects is illustrated at the example of the mangrove-fringed coastal Segara Anakan Lagoon in Java, Indonesia, which is fed by a river that drains an agriculture-dominated hinterland.
