“…Land use changes and different human activities were, therefore, modifying the ecological functioning of the wetlands. A similar study by Murungweni (2013) on Monavale wetland in Harare revealed that cultivation and settlement establishment resulted in clearance of land hence loss of biodiversity, habitat and aesthetic value of wetlands. Therefore, LULC changes result in wetland deterioration especially in rural communities where dependency is very high a situation observed by Phethi and Gumbo (2019).…”

The study assesses drivers of wetland utilisation patterns and the current status of provisioning and cultural services in Driefontein and Intunjambili wetlands, Zimbabwe. A total of 280 questionnaires were administered together with semi-structured interviews conducted with key informants in the two wetlands. Qualitative data obtained through the questionnaire survey and key informant interviews were analyzed using the content analysis method. The majority of the households in Driefontein (86%) and Intunjambili (75%) indicated that there is no change in wetland utilisation patterns over the past decade as horticultural activities remain the predominant activity. Most households (90%) in Intunjambili indicated that the availability of water is the major factor influencing wetland use. This was different from Driefontein where market availability for horticultural products (66%) was the main reason for wetland use. Land use land cover (LULC) changes established through analysis of remotely sensed imagery for the years 1999, 2009 and 2019 indicate an increase in the spatial extent of the cultivated area, bare land and a decrease in the area covered by water. Results also show that the two wetlands are providing water for drinking and crop cultivation, pasture for livestock grazing and opportunities for academic incursions. Overall, the two wetlands provide essential provisioning and cultural services hence the need for wise use and proper management to prevent their degradation and possibly loss of human benefits.

“…Therefore, the wetland presents an important opportunity for tourism. Studies by Murungweni (2013) and Mandishona and Knight (2019) considered wildlife viewing and bird viewing in wetlands as important recreational activities. More so, wetlands present opportunities for tours for academic incursions.…”

“…In addition, Nyamasyol and Kihima (2014) observed that in Kenya, land use changes over the past three decades characterized by a noticeable increase in the size of farmland, settlement, and other lands and a decline in forestland, grassland, wetland, and woodland have affected the Kimana Wetland ecosystems. Murungweni (2013) using GIS equally observed a decline in the quality of urban wetlands in the Monavale Wetland in Harare.…”

<p>Wetland ecosystems in the world have been affected by changing land uses brought about by rapid urbanization. The thrust of this study therefore is to examine the trend of land use dynamics and their implications on wetland management. Using land use maps for two periods – 1984 and 2014, aided by the administration of 75 semi-structured questionnaires, we exploited the rate of change of land uses and their effects on wetland management as well as the urban development policy implications for Bamenda. A positive relationship (0.5) was observed for land use change and wetland degradation. Furthermore, the results from land use analysis showed that between 1984 and 2014, significant changes were observed for residential land use which increased in surface area from 42% as of 1984 to 53% in 2014. In addition, agricultural land use increased from 11% to 34%. Conversely, the surface area covered by wetlands reduced from 27% in 1984 to 6% in 2014. The conclusion drawn is that in the face of further wetland degradation, the current trend of land use dynamics can be checked by the application of zoning laws to control the changes witnessed in the land uses (residential and agricultural land uses). In addition, the Bamenda City Council should promote public awareness through sensitization on wetland resources and should actively encourage the participation of the public, local government authorities and institutions in sustainably managing wetlands. </p>

“…Azous and Horner (2000) note that urbanization could have both direct and indirect impacts on wetlands. Typically, housing and other infrastructural development activities impact wetlands by resulting in habitat loss, hydrological alterations and reduces water quality (Murungweni 2013). Azous and Horner (2000) also detail out some indirect impacts of urbanization on wetlands.…”

Exploring the effects of rapid urbanization on wetlands: insights from the Greater Accra Metropolitan Area, Ghana

et al. 2021

View full text Add to dashboard Cite

Wetlands are important ecological resources that provide immense socioeconomic and ecological services. Despite these services, their sustainability, especially in the cities in the Global South, is undermined by anthropogenic activities such as farming, sand and salt winning, among others. The region's rapid urbanization is expected to exacerbate the threats. However, in the Ghanaian context, only few studies have explored the effects of rapid urbanization on the availability and sustainability of this important environmental resource. To address this research vacuum, the present study employed mixed-methods to explore the effects of urbanization on the wetland ecosystem in the Greater Accra Metropolitan Area (GAMA) of Ghana. There results indicate a negative statistical association between rapid urbanization and the availability of wetlands in GAMA. Additionally, the results of the study have shown that land-use activities along wetlands undermine the quality and sustainability of this environmental resource. Given this context, the study recommends that the appropriate institutional regimes (such as the Environmental Protection Agency, Town and Country Planning Department and Accra Metropolitan Assembly) institute strict buffer restrictions along these wetlands to mitigate human encroachment as well as intensify awareness campaigns to expose people to the values and benefits of this important ecosystem.
