Chapter
Full-text available
Wetlands are a key habitat within the Mediterranean biodiversity hotspot and provide important ecosystem services for human well-being. Remote sensing (RS) has significantly boosted our ability to monitor changes in Mediterranean wetlands, especially in areas where little information is being collected. However, its application to wetlands has some...
Article
Full-text available
The wetlands are often coupled with anthropogenic systems. This makes them highly dynamic, and thus difficult to map and monitor from space. The Sentinel-1 constellation allows monitoring land changes regardless of cloud conditions and with a high frequency of pass. We use a time series of 33 Sentinel-1 dual-polarized images from 2016 to map season...
Article
Full-text available
Wetlands are abundant across the African continent and provide a range of ecosystem services on different scales but are threatened by overuse and degradation. It is essential that national governments enable and ensure the sustainable use of wetland resources to maintain these services in the long run. As informed management decisions require reli...
Chapter
Wetlands are among the most vulnerable, threatened, valuable, diverse, and heterogeneous ecosystems existing on our planet. While they provide invaluable ecosystem services to our society, they have been declining globally for many centuries. Monitoring of these changes is necessary for implementing efficient conservation policies and sustainable m...
Chapter
This chapter underlines the need for interdisciplinary and transdisciplinary research to support drought risk monitoring for sustainable development using Earth observation (EO)‐based information products and socioeconomic statistics. While a large number of drought indicators already exists, clear guidance on how to embed these into policy advice...
Article
Wetlands are the most fragile and threatened ecosystems worldwide, and also one of the most rapidly declining. At the same time wetlands are typically biodiversity hotspots and provide a range of valuable ecosystem services, such as water supply and purification, disaster risk reduction, climate change adaptation, and carbon sequestration. Pressure...
Article
Full-text available
Wetlands are highly dynamic, with many natural and anthropogenic drivers causing seasonal, periodic or permanent changes in their structure and composition. Thus, it is necessary to use time series of images for accurate classifications and monitoring. We used all available Sentinel-1 and Sentinel-2 images to produce a national wetlands map for Alb...

Full-text available
Sub-Saharan African (SSA) wetlands are increasingly brought into focus as a possibility to increase food security. Accordingly, agricultural development in Rwanda’s extensive wetland landscapes is strongly promoted. However, agricultural use is a major reason for wetland degradation and often in conflict with conservation efforts. Detailed and up-t...
Technical Report
Full-text available
There is a growing awareness that data obtained from Earth Observation (EO) has the potential to provide the information needed for accurate wetland inventory, assessment and monitoring, and for updating a number of data fields in the Ramsar Sites Information Sheets (RIS). The latter includes: the physical features of the wetland, the presence and...

The DeMo-Wetlands project is funded by the German Aerospace Center (DLR) with funds from the German Federal Ministry for Economic Affairs and Energy. Its goal is to demonstrate the potential of current remote sensing tools for supporting international initiatives and conventions by strengthening national capabilities for mapping and monitoring of w...
Article
Full-text available
The impacts of agricultural expansion on wetlands are diverse and complex. Land surface temperature (LST) has a great potential to act as a global indicator of the status of wetlands and changes in their hydrological and evapotranspiration regimes, which are often linked to land use and cover changes. We use the whole MODIS LST archive (2000-2017)...

River discharge is a critical water cycle variable, as it integrates all the processes (e.g. runoff and evapotranspiration) occurring within a river basin and provides a hydrological output variable that can be readily measured. Its prediction is of invaluable help for many water-related tasks including water resources assessment and management, fl...

Full-text available
Wetlands provide many essential ecosystem services, but at the same time they are threatened by processes like e.g. urbanization, expansion of farmland and extraction and pollution of freshwater. Due to their heterogeneous characteristics, spatiotemporal dynamics and topographic features, wetlands are often hard to identify, map and monitor, which...

Full-text available
Using Landsat 5 and Sentinel 2 imagery we produce LULC maps for three periods in time for the Kilombero Floodplain, in Tanzania. Maps show farm encroachment patterns that have taken place during the last 25 years. LULC change trends can be estimated from these maps. Combining the data with Sentinel-1 time series may be possible to distinguish other...
Article
Full-text available
Automated monitoring systems that can capture wetlands' high spatial and temporal variability are essential for their management. SAR-based change detection approaches offer a great opportunity to enhance our understanding of complex and dynamic ecosystems. We test a recently-developed time series change detection approach (S1-omnibus) using Sentin...
Conference Paper
Full-text available
Wetlands are hot spots of biodiversity and provide a wide range of valuable ecosystem services, but at the same time they globally are one of the fastest declining and most endangered ecosystems. The development of a Global Wetland Observation System (GWOS) that is supported by the Ramsar Convention on Wetlands since 2007 is seen as a step towards...

Presentation
Full-text available
Monitoring of long-term land-use and land-cover change patterns may be biased by seasonal changes of different surface properties (e.g. hydrology, phenology, etc.) which become even more prominent in highly dynamic ecosystems such as wetlands (Crews-Meyer, 2008; McClearly, Crews-Meyer and Young 2008; Dronova et al. 2011). These surface dynamics pro...
