Climate change impacts on coastal wetlands. University of Antwerp

Stijn Temmerman
Ecosystem Management
Coastal wetlands, such as salt marshes and mangroves, are valuable ecosystems that are vulnerable to climate change. Sea level rise and increasing storm frequency and intensity may lead to increased flooding of coastal wetlands, and finally may cause the die-back and erosion of salt marshes or mangroves. In this project we want to study the adaptability of coastal wetlands to increasing sea level and storminess. The dense vegetation of salt ...

Pollution in the coastal wetlands of East Asia: cascading effects from littoral macroinvertebrates to migrating shorebirds (COAST-IMPACT). University of Antwerp

Globally, coastal ecosystems are undergoing rapid changes with respect to habitat degradation and pollution, which is especially true along the East Asian coastline due to rapid industrial and urban development. This has led to effects on coastal wetlands in terms of biodiversity and also on the quality of the stopover sites for migrating birds, such as shorebirds. Shorebird populations are declining at an alarming rate along the East Asian ...

Coastal wetland response to sea level rise: an integrative marsh – mangrove study on soil elevation and soil carbon response. University of Antwerp

Stijn Temmerman
Ecosystem Management
Coastal wetlands, such as tropical mangrove forests and salt marshes in temperate climates, are unique ecosystems that are often feared to be lost by sea level rise. They can however adapt to a rising sea level to some extent by raising their elevation via sediment accumulation, and they can mitigate climate warming by storing carbon from the atmosphere into their soils. Present insights into the feedbacks between the rates of sea level rise, ...

Coastal wetland response to sea level rise: an integrative marsh – mangrove study on soil elevation and soil carbon response KU Leuven

Soil and Water Management, Geography and Tourism

Coastal wetlands, such as mangroves and marshes, are unique ecosystems that are often feared to be lost by sea level rise. However they can adapt to a rising sea level to some extent by raising their elevation via sediment accumulation, and they can mitigate climate change by storing carbon into their soils. Present insights into the feedbacks between sea level rise, sediment and carbon accumulation mainly come from studies on marshes, while ...

Sabbatical Steven Bouillon: Biogeochemistry of tropical wetlands KU Leuven

Steven Bouillon
Soil and Water Management

The main goal of this sabbatical is to strengthen and revigorated our key research niche, i.e. studying the biogeochemistry of tropical aquatic systems using state-of-the-art analytical techniques. My research combines a focus on tropical aquatic ecosystems, and the use of stable isotope proxies to study element cycles across a range of ecosystems – from highland streams to rivers, lakes and reservoirs, floodplains, down to the coastal zone. ...

Nature-based climate adaptation in the coastal zone: demonstrating the key role of spatial self-organization of coupled plant species zonation and wave attenuation in tidal marshes. University of Antwerp

Stijn Temmerman
Ecosphere
Tidal marshes are increasingly proposed as nature-based shoreline protection against climate change induced sea level rise and increasing storminess. In this project I address the following key knowledge gaps on the effectiveness of this nature-based climate adaptation function: how do two-way interactions between plants and waves lead to spatial self-organization of species zonation and wave attenuation, and how does this self-organization ...

Mangroves as a coastal defense strategy: using drones and smartphone LiDAR sensors to quantify mangrove-induced friction in flood models. University of Antwerp

Stijn Temmerman
Ecosphere
Mangroves play an important role in coastal protection in tropical deltas by exerting friction on incoming water flow and as such attenuating incoming extreme sea levels (e.g. storm surges, tsunamis). In order for models to realistically predict this attenuation of flood propagation by mangroves, we need to drastically improve the quantification of mangrove-induced friction on the water flow. We will test the possibility to use drones and ...

Local to global variability in organic carbon dynamics in coastal marsh sediments subject to submergence by sea level rise. University of Antwerp

Stijn Temmerman
Ecosphere
Coastal marshes are among the most effective ecosystems that can mitigate climate warming by sequestration of carbon into their soils. But the climate warming in itself is impacting coastal marshes through sea level rise and there is much uncertainty about the impact on soil carbon accumulation and preservation. Our objective is to advance understanding of the global and local variability in the accumulation and preservation of different sources ...

Coastal marsh resilience to sea level rise: a field, flume and modelling study on the role of bio-geomo hic self-organization. University of Antwerp

Stijn Temmerman
Ecosphere, Utrecht University, Ecosystem Management
Tidal marshes are valuable coastal ecosystems that are threatened by global climate warming and resulting sea level rise. Whether they drown or continue to exist while sea level rises, depends on the trapping of sediments (sand and mud) that builds up the land surface. The sediment trapping is locally determined by so-called bio-geomo hic interactions between plants, water flow, and landform changes. However, the larger landscape also ...
