    Incentive mechanism for promoting the uptake of green building in South Africa
    (Emerald Publishing, 2024) Simpeh, Eric Kwame
    Purpose: The green building (GB) market is maturing after years of practice; therefore, incentives for promoting GB should be adapted to reflect the market transformation. Adapting incentives can positively influence stakeholders' motives, which in turn change stakeholders' behavioural intention towards GBs. Hence, this study aims to examine the parameters influencing the decision to adopt GB and to ascertain how incentive mechanisms promote the uptake of GB in South Africa. Design/methodology/approach: Using a scoping literature review and a sequential mixed research method, primary data were acquired from GB experts in four South African provinces. In analysing the quantitative data, the factors were ranked hierarchically using the mean ranking technique and factor analysis was computed to identify the underlying GB incentives. The qualitative data were analysed using content analysis. Findings: The results indicate that incentive payment from a utility energy efficiency programme, rebates and discounts relating to environmentally friendly materials and products and providing grants to homeowners and developers to go towards certification were the most essential monetary incentives for promoting GB. In the category of non-monetary incentives, recognition of consultant team members and developers and free marketing/good publicity were the most important incentives. The incentive mechanisms were subsequently categorised as “Economic incentives” and “Reward scheme and technical support”. Research limitations/implications: This study was confined to four metropolitan areas in South Africa. Nevertheless, the outcomes have practical implications for GB projects in general and may serve as a good reference for other provinces in South Africa. Originality/value: The findings of the study are a valuable resource for stakeholders such as the government, municipal assemblies, professional bodies and the Green Building Council of South Africa (GBCSA) in developing effective incentive mechanisms to promote GB adoption. This study adds to the body of knowledge relevant to GB incentivisation in South Africa.

    Perception of the services and disservices from urban forest and trees in the Garden City of West Africa
    (Elsevier, 2024) Mensah, Henry; Simpeh, Eric Kwame; https://orcid.org/0000-0001-8807-9697; https://orcid.org/0000-0002-5123-7468
    The growth of trees in urban areas brings forth an extensive array of services and disservices, the comprehension of which can assist urban forestry professionals in advancing a more sustainable urban forest ecosystem. This paper assesses the perception of urban residents on the services and disservices from urban trees in a less represented geographic area. Using a mixed method approach, primary data was gathered from 396 urban inhabitants in the study area. Exploratory factor analysis was used to assess perception of services and disservices from the urban trees. Using a principal component analysis, it was found out that the most important services provided by urban trees were health and climate improvement as well as energy, esthetic and environmental benefits. These services explained 50.8% of citizens’ perception variance and are linked to basic human needs. Additionally, the Monte Carlo parallel analysis-based on exploratory factor analysis revealed that the underlying problems that needs to be addressed were related to poor management and maintenance of urban trees, destruction of infrastructure by trees and issues related to safety including parks and gardens serving as hideouts for criminals in the city. These components were predicting 53.3% of the problems and disservices of urban trees. The results provide a valuable insight for urban forestry professionals. The findings imply that institutional assistance should be increased, and the legislative structure changed to address these challenges to sustain urban forestry.
