Sustainable Development Ensued by Social Capital Impacts on Food Insecurity: The Case of Kibera, Nairobi
The aim of this study is to disclose the social factors of sustainable development goals by exploring the links between three types of social capital (bonding, bridging and linking) and food security in Kibera, an informal settlement located in Nairobi, Kenya. Several studies in the literature have addressed links between food security and social capital. However, a lack of theoretical approaches exist in the literature, which concern the sustainable development theory devoted to urban areas taking into account the sustainable development goals. This study applies a linear regression model on data from 385 households in Kibera to analyze the connection between food security and three types of social capital (bonding, bridging and linking). The results demonstrate that there is a positive impact between our proxies for bonding social capital (cultural diversity and the number of visits to area of origin) and food security. Bridging social capital (measured by trust in strangers) demonstrated a negative impact on food security. Finally, one indicator for linking social capital demonstrated a positive impact on food security (trust in community leaders), whereas the statistical analyses did not find any relationship of the two indicators; ‘trust in local politicians’ and ‘membership of social organisations’, with food security. The results demonstrate that insight into social capital can inform the understanding of household food insecurity in vulnerable urban settlements, by illustrating the critical impacts of social drivers in a food system.

Does certification improve hired labour conditions and wageworker conditions at banana plantations?
Certification of banana plantations is widely used as a device for protecting and improving socio-economic conditions of wageworkers, including their incomes, working conditions and—increasingly—voice [related to labour relations and workplace representation]. However, to date, evidence about the effectiveness of certification in these domains is scarce. We collected detailed field data on (1) economic benefits for improving household income, (2) social benefits for labour practices, and (3) the voice of wageworkers focusing on identity and identification issues amongst wageworkers at Fairtrade certified banana plantations and comparable, non-certified plantations in the Dominican Republic. We used different types of regression models to identify significant relationships. Econometrical analysis of survey results complemented by field observations and outcomes from in-depth stakeholder interviews indicate that the impact of Fairtrade certification on wageworkers’ economic benefits is rather limited. However, the impact on the voice of wageworkers (job satisfaction, sense of ownership, trust), is more evident. On Fairtrade certified plantations workers are more satisfied with the course of life and better represented. Thus while the additional value of Fairtrade certification on primary wages seems limited, Fairtrade has relevant positive effects on the labour force, particularly by delivering in-kind benefits, offering a sense of job-security, improving voice and enabling private savings. Benefits of (Fairtrade) certification, but also other interventions with a similar purpose, might therefore not be discerned in terms of economic benefits such as wages or basic labour conditions that are under direct control of (inter)national law, but they should be identified in terms of social benefits and improved norms of conduct for wageworker engagement.
