Sea levels are rising due to global warming, which is induced by anthropogenic activities increasing the concentration of greenhouse gas emissions in the atmosphere. Sea level rise is already causing a severe impact on coastal wetland ecosystems, and the influence will intensify in the future. One of these coastal ecosystems is mangrove forests, which grow in intertidal zones and are therefore subject to tidal water level fluctuations. Mangrove forests provide essential ecosystem services to coastal environments and societies, and their exposure to sea level rise is a significant concern. The consequences of sea level rise, such as inundation, erosion, and lack of accommodation space, will increase the extent of mangrove loss. It is therefore essential to fully understand how sea level rise is influencing mangrove ecosystems in different geographical locations, and how likely they are to adapt and survive under different scenarios. This research used a systematic literature review to assess scientific articles from various regions, investigating the current knowledge regarding the impacts of sea level rise on mangrove ecosystems. The information was collected from 40 articles, which covered studies from five continents. The findings affirmed that the negative effects of sea level rise on mangrove ecosystems are recognized globally. It is well understood that, by the second half of the century, mangrove ecosystems will face severe issues if the highest IPCC emissions scenarios are reached. It is further well acknowledged that mangrove forests provide important ecosystem services, for example, by protecting the coastal areas under extreme weather events, benefiting natural resources sectors and recreation, and further delivering crucial climate change mitigation services by sequestering and storing blue carbon. It is therefore essential to recognize mangroves as an important ecosystem and treat them adequately. Mangrove ecosystems’ resilience under sea level rise was commonly found to be dependent on their hydro-geomorphological environment. Under sea level rise, one of the most significant factors contributing to mangroves’ survival and resilience was the availability of accommodation space, which they need to be able to migrate inland as the sea levels rise, along with their ability to adapt to changes in sediment elevation rates. To secure the needed accommodation space and to further help mangrove ecosystems grow and live under the sea level rise scenarios, adequate climate change adaptation strategies must be planned and adopted. These strategies include prioritizing high-priority areas for vegetation growth, estimating areal habitat suitability, strengthening the understanding of land use impacts on mangrove forests, and implementing hybrid solutions for coastal protection. Although the issue of sea level rise influencing mangrove ecosystems is well recognized globally, there was an observed lack of adequate research. Further research and improved understanding are needed to ensure that preparation for all emission scenarios, even for the worst ones, is possible and that climate change adaptation strategies will be well implemented.
