The cross-sectional study was aimed at assessing the contribution of social entrepreneurship to sustainable community development in Zimbabwe using case study approach. The behavioural theory of social entrepreneurship and the community development theory guided the study. Mixed research methods were used guided by the pragmatist research philosophy. A case study was used with a sample of 80 participants selected from four farming communities in and around Harare using stratified random sampling and judgement sampling techniques. Data collection was done through questionnaires and interviews. Data analysis was done using SPSS version 25.0 for quantitative data, NVIVO and thematic analysis for qualitative data. The findings indicate that there is limited knowledge of social entrepreneurship concept amongst research participants. However, there was greater appreciation of the sustainable community development concept. The findings also revealed that there are some challenges for the social entrepreneurship ventures and the communities that retard sustainable community development in the country. The study recommends proper information dissemination channels, more capacity building initiatives through specific grants to support social entrepreneurship organisations and the crafting of an Act that guides social entrepreneurship ventures independent of other NGOs.

The study examined the extent of social media usage by construction industry MSMEs in Harare guided by Chaffey's theory. A sample of 119 was drawn from CIFOZ and SMEA, using systematic and purposive sampling techniques. Questionnaires and interviews were used for collection of data which was analysed using SPSS and Nvivo. The instruments had a Cronbach alpha index of 0.72 implying validity. The findings showed that there was greater appreciation and motivation towards adopting social media tools among the participants and the MSMES in the construction sector in Harare. The study, therefore, concludes that knowledge, skills and motivation towards social media marketing tools are abundant among MSMEs in the construction sector contrary to apriori expectations. The results also show that social media marketing offers the opportunity for a high number of social interactions for businesses to expand product/brand awareness as well as offer a feedback mechanism. The study, therefore, concludes that social media has a diverse and plethora of benefits that can be enjoyed by construction MSMEs in accentuating and perpetuating the growth of MSMEs in the construction sector in Zimbabwe. It is recommended that firms invest in the training of their staff on social media skills as well as in the acquisition of technology infrastructure for the adoption of social media marketing. It is further recommended that MSMEs take the next step in digital use by creating measuring tools to enable them to measure the contribution of social media marketing to the growth of their businesses.
