BESE Bridging Tresholds

Developing multipurpose biodegradable structures for generating ecosystem services

Worldwide, wetland ecosystems (e.g. peatlands, salt marshes, marine reefs) provide vital ecosystem services, representing a total value of 33 trillion US$ per year. However, despite increasing awareness of the ecological and socio-economical importance of wetlands, many have been either lost or degraded in the last three decades. Despite high costs invested in restoring wetland ecosystems (up to 1,000,000 US$/ha) success is generally below 50%.

Testing degradable matrix to trap mussel seeds, in Oosterschelde.

Restoration is so difficult because wetland stability depends critically on self-facilitating feedback created by habitat modifying organisms that dominate these ecosystems, creating a ‘chicken-and-egg problem’. We propose to develop multipurpose Biodegradable Elements for Starting Ecosystems (BESE) that temporarily facilitates habitat modifiers, thereby bridging critical thresholds and enabling ecosystem development in degraded wetlands, thus creating a viable product for global application.

New website for NIOZ

This year we are going to redesign and technically improve the NIOZ website. We would like to take your opinion as website visitor into account.

By answering 10 questions you can help us enormously! It will take you no longer than 4 minutes. You can win a NIOZ t-shirt and a book voucher to the value of EUR 25 if you fill in the questions.

Thank you for your help!

No, sorry! Yes! I'll help out!
