“…In their study, Balwan & Kour (2021), the authors claimed that wetlands offer benefits that no other ecosystem can, even though they are often weak, disease-ridden areas. These include chances for enjoyment and aesthetic appreciation, flood protection, coastline erosion prevention, natural water quality improvement, and free access to genuine items.…”

Purpose: Wetlands are assets in the country, and they help make cities lockable and attractive. The study aims to assess the spread of alien invasive plants that affect the wetlands and construct a policy framework that could be used to preserve and conserve groundwater resources (Wetlands) in urban areas of Mpumalanga Province, specifically White River. This research will answer why alien invasives are a threat to wetlands. Methodology: The study was conducted in White River on Longtom Street. A single observer conducted fixed-width line transect surveys to investigate species richness and abundance for all the untreated species detected next to the wetland. Three transects per habitat type were visited twice through twice per week. Main Findings: During the survey, seven different alien invasive species were observed. The leading species was Solanum mauritianum, followed by Chromolaena odorata species; the third most dominant species was Lantana camara and Tecoma stans. Most species observed were illegally dumped by the residents that stay closer to the wetland, and no awareness, information, and training about the importance of wetlands were provided to the residents. Implications: The framework can do more to help local communities manage urban wetlands, identifying opportunities for mapping and functional assessment to improve restoration and protection efforts. It can facilitate research and peer-to-peer exchange on innovative funding and financing methods for nature-based projects. Novelty: Findings and recommendations resulting from this study will be summarized into a strategic guide by the end of 2023. It is recommended that all alien invasive plants in the wetland be eradicated. Wetlands must be protected to improve human health and well-being.

“…Wetlands, as mentioned before, have a wide range of functional values, both ecological and economic, each wetland depends on its location, size, and relationship to adjacent land and water areas (US EPA, 2016), and is crucial for both chemical decomposition and as carbon sinks (US EPA, n.d.). Their values include habitat for aquatic birds and other animals and plants, numerous threatened and endangered species; production of sh and shell sh; provision for agriculture; water storage, including mitigating the effects of oods and droughts; water puri cation; timber production; food production; education and research, and recreational value (Keddy et al, 2009;Davidson, 2014;Balwan & Kour, 2021) as well as recharging of aquifers. Some dominant greenhouse gases such as methane, carbon dioxide, and nitrous oxide play an important role in climate change, which results in global warming potential.…”

Quantifying the role and bene ts of wetlands to environmental security, ecosystem sustenance, and economic development is a very di cult task.Wetlands serve as lters of secondary wastewater by removing most nutrients that cause eutrophication. The plants and microbes in the natural wetland have the potential of breaking down toxic compounds into less toxic forms before they are discharged into streams, rivers, and lakes. Natural wetlands could serve as treatment plants in most developing countries if they are managed sustainably. Unfortunately, most developing countries that lack waste treatment plants have not taken the advantage of available natural wetlands and managed them sustainably. This study investigates sustainable wetland management on the Iture-Abakam Natural Wetland in Cape Coast by considering the management plan available and the threat posed by urbanization. The ndings reveal the absence of a management plan and the serious threat posed to the wetland. The study revealed a net wetland loss of 83.2% to residential development between 1991 to 2021. The ndings from the water quality analysis show that the wetland is performing poorly in treating wastewater as revealed by the quality and pollution indexes used. The potential of the wetland is high if it is managed sustainably.

“…Wetlands provide socio-economic benefits to society in addition to fishing and recreational activities (Islam et al, 2023). They also maintain the nutrient cycle in neighbouring agricultural regions, improve water quality, sequester carbon, and reduce floods in coastal areas (Balwan & Kour, 2021;Mitsch & Gosselink, 2015;Reddy et al, 2010). The plants found in wetlands serve a critical role in the wetland ecosystem's food chain and energy flow.…”

Wetlands are an integral part of our global ecosystems and play crucial roles in ecological functions such as carbon sequestration, flood mitigation, water purification, and recreational activities. The Ramsar Convention is the most significant wetland protection pact and is doing tremendous work in conserving wetlands worldwide. However, the wetlands area is still under threat due to anthropogenic activity. The current study utilized drone images, chlorophyll measurements and machine leaning to discriminate and map vegetation at marsh wetland area—the Ramsar site. The high‐resolution, multispectral imagery is acquired using a drone‐mounted MICAsense sensor. Eight spectral indices such as Normalized Difference Water Index (NDWI), Two‐Band Algorithm (2BDA), Normalized Difference Chlorophyll Index (NDCI), Normalized Difference Vegetation Index (NDVI) Enhanced Normalized Difference Vegetation Index (ENDVI), Green Normalized Difference Vegetation Index (GNDVI), and Normalised Difference RedEdge (NDRE) were calculated on the acquired imagery in order to discriminate the different vegetation covers such as floating aquatic vegetation (FAV), open water, and other vegetations types. These include the following: Eichhornia, Nymphea, Oleracea, Paspalam, and Oryza from agriculture land at the study site. Two models (viz., the Taylor plot and the Lek Profile methods) were employed to assess the sensitivity of the spectral indices for prediction of chlorophyll and vegetation discrimination. It is inferred from both methods that NDCI was most sensitive for chlorophyll prediction of vegetation followed by NGRDI/ ENDVI/ 2BDA and NDVI for chlorophyll prediction in wetland ecosystems. Further, three machine learning algorithms, support vector machine (SVM), random forest (RF), and gradient tree boost (GTB), were utilized for classification, and the performance accuracy of GTB was found to be the highest (0.893), followed by RF (0.851) and SVM (0.723). The GTB algorithm was applied over NDCI for vegetation discrimination. The study revealed that Eichhronia sp. is abundantly present at the study site; hence, strategic management plans should be carried out for the eradication of invasive species and proper management of wetland vegetation.
