“…In this study, Leguminosae, Moraceae, Lamiaceae, Myrtaceae, Arecaceae, Combretaceae and Meliaceae were found to be the predominant families. Similar findings to ours were reported in the floristic composition of several cities, where they enjoyed the same status [15,[49][50][51][54][55][56][57]. The number of families obtained in the road buffer zone is in the range of 14 to 27 families mentioned for others cities [30,[55][56][57].…”

“…With regard to stratum, the proportion of exotic plant species is 48.84% in the residential zone, 50% in the institutional zone and 53.85% in the road buffer zone. The predominance of exotic species in the road buffer zone was consistent with the results obtained in Kumasi Metropolis (Exotic/Native: 64.29%/35.71%) [56] and Bangalore (Exotic/Native: 67%/33%) [65]. The variation in the proportion of exotic plant species between strata is related to the management practices, planting decision-making process and the level of knowledge of the managers on the floristic composition of the urban area.…”

The need for sustainable and green cities highlights the importance to improve plant species diversity in urban areas. We assessed the phytodiversity of three management units (strata) to enhance plant species conservation planning in Lokossa City. A forest inventory was conducted in each stratum based on one-hectare sample plots. Fifty plots were distributed following a stratified random sampling approach. We found that 53 plants species belonging to 46 genera and 22 families were established in the strata. However, the flora of the city was mixed with 50.94% of native plant species. The dominant families were Leguminosae, Arecaceae, Malvaceae, Moraceae, Combretaceae, Lamiaceae and Myrtaceae. The ten most important plant species accounted for 69.31% of the total abundance. Khaya senegalensis (Desv.) A. Juss. and Mangifera indica L. were dominant plant species. Ubiquitous species accounted for 54.72% of species pool and 82.92% of all individuals. The flora of residential zone was more diversified than those in road buffer and institutional zones. Which contributed to 60.27% of all individuals. The road buffer and institutional zones flora were quite similar. Therefore, we suggested that the planting and monitoring projects should be detailed and budgeted with reference to plausible scientific knowledge in the city development plan. The creation of participatory botanical gardens at the city neighborhoods scale. The integration of the flora of residential zone in species conservation projects in order to increase global diversity and storage of biomass in the city.

“…Although the dominance of native species over the exotic ones was highlighted (Nyambane, Njoroge, Watako, & Onyango, 2016;Uka & Belford, 2016;Yan & Yang, 2017), studies show increasing dominance of exotic species and their accompanying richness above the surrounding natural or semi-natural habitats (Morgenroth et al, 2016).

Progress and Methodological Approaches in Urban Trees and Forests Research in Africa

The numerous benefits of urban trees and forests are being increasingly recognised globally but grossly under studied in the developing world. This paper reviewed the methodological approaches to urban trees and forests assessments in Africa in relation to the growing number of publications in the field between 2012 and 2017. It adopted a comprehensive search of online publications related to urban trees and forests in the Google Scholar, Springer, Science Direct, Scopus, IEEE, Tailor and Francis and African Journals databases. Number of publications increased steadily from 2 in 2012 to a cumulative total of 44 in 2017, most of which were however, from South Africa, Nigeria and Ghana with little contributions from Kenya and Rwanda. Although remote sensing may facilitate detailed studies of urban trees, most researchers used the traditional and time-consuming field surveys and to some extent, interview and questionnaire surveys. African cities are highly diverse in both native and exotic tree species but the exotic species dominate in many areas. Urban trees in Africa provide both tangible and intangible benefits which include provision of income, fruits, medicines, fuelwood and recreation opportunities. Others are micro-climate modification, erosion and desertification control, pollutants removal, spirituality and aesthetics. Advances in urban tree assessments such as the use of i-Tree Eco and i-Tree Streets, high resolution remote sensing images and LiDAR should be explored. Governmental and private organizations need to be more committed to urban trees research and management through enhanced funding.

“…Study in Old Fadama, Accra, shows that the introduction of green infrastructure was socially resisted, politically and economically opposed (Tauhid and Zawani 2018). Moreover, Kumasi, once dubbed "Garden City" of West Africa because of its lush vegetation cover (90% in the 1970s and earlier), has witnessed a decline in green cover over the years to about 50% (Campion and Odametey 2012;Mensah 2016;Cobbinah et al 2020;Abass et al 2019) high diversity of the tree species in Kumasi (Uka and Belford 2016), there is rampant destruction of urban trees, which has resulted in environmental degradation. A similar incident has occurred in cities such as Accra, Tamale, Takoradi, Sunyani and Obuasi.…”

Resilience to climate change in Ghanaian cities and its implications for urban policy and planning

et al. 2021

View full text Add to dashboard Cite

City authorities across the globe have resolved to make their cities sustainable and inclusive. However, resilience of cities to climate change, which is a vital component of the sustainable city development process, is a challenge, especially in the global south. This paper sought to critically examine the resilience of Ghanaian cities and explore ways to enhance their resilience in a sustainable manner. To address this key objective, answers to the following specific questions were sought: (1) Are the Ghanaian cities prepared to face future climate uncertainties? (2) How resilient are the Ghanaian cities? (3) What is the way forward for building resilience in the Ghanaian cities? The paper draws on urban resilience studies from academic databases such as SCOPUS, Web of Science, Google Scholar and ERIC. Focusing on disaster management, green infrastructure, land-use and urban planning, institutional structures and community engagement in the analyses of literature, the results show that Ghanaian cities remain vulnerable and largely dependent on human activities to achieve resilience. For instance, there is limited financial support for disaster response and understanding of urban resilience principles. More so, failure to enforce land-use planning regulations has led to the growth of unauthorised development, waste management problems and destruction of urban green spaces. The study provides a valuable contribution to the discourse on resilient cities in urban areas by specifically addressing the challenges related to urban resilience to achieve sustainable cities in Ghana. We propose that capacity for disaster risk reduction, institutional collaboration and enforcement of urban planning regulations should be strengthened.
