Mangroves in Bragança, Brazil

Through their ecosystem services, mangroves offer the inhabitants of tropical coastal areas a livelihood and protect their homes from coastal erosion and storm floods. But mangroves are also important for Europeans, as they contribute to the provision of tropical seafood. Moreover, because of their ability to store greenhouse gases, they counteract the continuously progressing climate change. Many of these ecosystem services are controlled – directly or indirectly - by the microorganisms of the mangrove sediment.

The use of natural resources by the local population and for export is not always sustainable and may have negative effects on the mentioned ecosystem services. This project will establish in a global comparison of different types of mangroves a connection between mangrove ecology and socio-economy, by means of modern methods of biology, chemistry and social sciences.

For this purpose we want to investigate how the local and regional flora and fauna and their use by human populations affect the microorganisms in the sediment and therefore major ecosystem services. Based on this knowledge, we will be able to make suggestions to decision-makers regarding the protection and the management of these important and vulnerable ecosystems.
