Citizen Science Approach for Assessing the Biodiversity and Ecosystem Service Potential of Urban Green Spaces in Ghana

Abstract

Urban green spaces are linked to good human health and well-being, sustainable cities and communities, climate action, life on land and under water, as well as offering a platform for quality nature-based education. Their efficient management will no doubt be necessary if strides are to be made in efforts to protect biodiversity and enhance ecosystem service delivery in urban areas. This will, in part, require building the capacity of community members as citizen scientists to take up conservation roles. This study explored the levels of biodiversity and the proxy-based ecosystem service potential of urban green spaces in Sunyani, Ghana, using citizen science approaches. The green spaces accessed were the University of Energy and Natural Resources Wildlife Sanctuary and Arboretum, the Sunyani Parks and Gardens, the Sunyani Residency Park, and the Sunyani Senior High School Woodlot. The different levels of biodiversity (trees, arthropods) and ecosystem services were observed for the five green spaces assessed, with a significant relationship observed between arthropod communities and vegetation variables. Our results showed that citizen scientists perceived urban green spaces to supply more significant provisioning and regulating services than any other ecosystem services, even though they were highly dissatisfied with how green spaces are managed. The children’s perception of the composition of nature was slightly narrow, as they largely centered on plants and animals only. Even so, their awareness of the value of nature was high, as were the threats of human activities to nature. Citizen science approaches could complement biodiversity studies in data-deficient regions; however, collected data may require additional verification and validation from experts for conclusive and better inferences.

Urban Green Spaces in Africa: A Bibliometric Analysis

“…Initially concentrated on ecological conservation concerns, the research priorities refs. [55][56][57][58] have since shifted towards examining the various ecosystem services offered by urban vegetation [59][60][61][62][63]. Presently, there is a significant emphasis on investigating how these green spaces contribute to enhancing the public health and well-being of urban residents, indicating a noteworthy evolution in research trends within this field [64][65][66][67][68][69].…”
