Worldwide, the loss of biodiversity in wetlands, like rivers and their floodplains and peatland, but also in deltas and estuaries is dramatic. Reasons are intensive land-use such as farming and urbanisation, drainage, construction of levees or bank stabilisation, or straightening of river courses and coastlines. These impairments lead to a lack of typical functions of wetlands, such as carbon storage and habitat provision, which are major reasons for the decline of wetland ecosystem services and coastal biodiversity. Therefore, there is a huge need to restore dynamic processes of river-floodplain-coastal ecosystems to revitalise peatland, riverine landscapes and coastal wetlands, especially in the face of changing environment like increase of extreme events due to climate change. In the last decades all over the world, various restoration measures have been carried out to revitalise wetlands. Some of these measures already show success, others are on the way to improve wetland biodiversity and related ecosystem functions and services with the aim to implement international biodiversity goals and policies for adaptation to and mitigation of climate change.

The collection serves to bring together the very wide experience from science, policy and hands-on restoration of wetlands and coastal marine systems and to facilitate exchange among different disciplines.

In the collection we are looking for contributions addressing the following topics (among others): 

• How does restoration take place, coming from a biological but also from a planning or a societal background?
• How did the targeted biodiversity or selected ecosystem functions and services perform? What's about monitoring implementation to measure the effects?
• Showing synergies of wetland restoration and climate change adaptation (e.g  promotion of riparian vegetation and other floodplain typical habitats);
• What is the perception and acceptance of the surrounding society (stakeholders, land users, tourists etc.)?
• What are good biological indicators to measure effects of restoration?

Landscapes are composed of heterogeneous patches containing different habitat and land cover types that should be identified in order to assess structural and functional ecosystem properties. Most ecosystem services assessments use proxy variables derived from land cover or habitats classes as input. However, land use and habitats usually show temporal dynamics that reflect differences in the functions and services provided within and between years. In this regard, the assessment of functional attributes, such as vegetation phenology, can complement and improve habitat and land cover classifications based only on structural features by including vital ecosystem functioning properties. Similarly, it is now possible to remotely estimate realised use of ecosystems (e.g. using smartphone data or social media). As a matter of fact, our ability to monitor ecosystem functions, potential services and realised use by means of remote sensing has extensively improved in the last decades in relation to new sensors, higher data availability, new algorithms, new cloud computing facilities, etc.

This Collection will comprise a selection of research papers exploring new ways in which remote sensing can be used to assess and link ecosystem functions with services. We welcome contributions related to any of the following topics:

• Assimilation of remote sensing datasets into process-based models used to quantify ecosystem functioning, pressures and services provision.
• Mapping habitat functional types and services.Cloud and desktop-based remote sensing tools to assess ecosystem condition, functions and services.
• Case studies using remote sensing techniques and quantification of ecosystem services to improve the management of specific areas, for example through integration of Research Infrastructures with expert and stakeholder networks.
• Pioneer methods and tools that use earth observation technologies to enable ecosystem accounting, including measuring ecosystem extent and condition.
