“…Land reclamation projects have been especially prominent around the major coastal cities in Asia over the last two decades with considerable impact on coastal wetlands (Hu et al 2018;Sengupta et al 2020). Land is typically reclaimed for economic development but sometimes for coastal protection or even conservation, although there are often unanticipated and highly negative outcomes (Zhang et al 2017;Yang et al 2018b). Newton et al (2020) have recently presented an inclusive and comprehensive review of direct anthropogenic impacts on coastal wetlands.…”

As the focus of land-sea interactions, estuarine and coastal ecosystems perform numerous vital ecological service functions, although they are highly vulnerable to various kinds of disturbance, both directly and indirectly related to human activity, that have attracted much recent attention. Critical zone science (CZS) has emerged as a valuable conceptual framework that focuses on quantitative interactions between diverse components of the environment and is able to integrate anthropogenic disturbance with a view to predicting future trajectories of change. However, coastal and estuarine environments appear to have been overlooked in CZS and are notably under-represented, indeed not explicitly represented at all, in the global network of critical zone observatories (CZOs). Even in the wider network of environmental observatories globally, estuarine and coastal wetland ecosystems are only very rarely an explicit focus. Further strengthening of integrated research in coastal and estuarine environments is required, more especially given the threats these ecosystems face due to growing population at the coast and against the background of climate change and sea level rise. The establishment of one or more CZOs, or their functional equivalents, with a strong focus on estuarine and coastal wetlands, should be urgently attended to.

“…This indicates that the area is mostly under depositional processes as the river mouths run at low streamflow when compared to the upstream feeding rivers, hence the development of anti-dunes within the broad flat beaches. Within this geomorphic unit, the occurrence of quasi-horizontal laminae, which are found in the trenches of sedimentary morphostructural origin, is seemingly ubiquitous (Sexton & Murday, 1991;Isola et al, 2017;Zhang et al, 2017).…”

Geomorphological Mapping of Part of the Niger Delta, Nigeria Using Dem and Multispectral Imagery

This study utilised geo-information technology to carry out a geomorphological mapping of a part of the Niger Delta. Satellite image analysis was based on bi-annual seasonal approach using a combination of visual analysis of the geometry, site, situation, colour, and season for analysis of the non-topographic features. The study also utilised virtual and onsite fieldworks and existing geomorphologic information to interpret and analyse topographic and bathymetric features. First-order topographic features (elevation) and second level features including slope, aspect, curvature and mathematically exaggerated shaded relief were extracted from DEM. Relief classification was based on average elevation differences, hill shade, slope, and aspect. Three main non-topographic landforms were identified; the permanent rivers with stable meanders, perennially-active systems of creeks and fluvial landforms including scroll bars and oxbows. With the exception of higher elevation values towards the north-western fringe, the elevation ranges between mean sea level and 1 metre above sea level thus establishing a somewhat flat terrain. These areas were filled with meandering streams, sinuous creeks and watercourses flanked by mangrove vegetation. In the north-western area, elevation rose close to approximately 4 metres in most of the area with a peak of 10 metres. Generally, the cumulative area-slope analysis yielded a deltaic plain with generalised slope ≤ 20. Overall two elevation-based geographically differentiated morphological units were identified; tidal mudflats and saltmarshes. The study recommends that to provide needed information for resource planning and management, further investigation should be carried out with a view to modelling probable ecological and geomorphological changes in the entire Niger Delta.
