Background: Several state and non-state organizations are promoting organic agriculture as a climate smart option among cocoa farmers in the Ashanti region of Ghana. In this study, flora diversity and livelihoods position in organic and conventional farming were measured and compared. The experiment included 32 households with young plantations. Jaccard similarity, Shannon (H′) and Simpson (D) diversity indices were measured to assess species similarity, abundance, evenness and dominance. The sustainable livelihoods indicators were food security, income, vulnerability and well-being. Results: The results showed that the species are quite similar. The H′ index for organic farms was slightly higher (0.808) than that of conventional farms (0.762); the D index (0.051) for organic was better than the conventional (0.084). The organic farmers studied had better sustainable livelihoods outcomes than the conventional farmers. Conclusion: Since organic farming has more biodiversity, farmers should be encouraged to practise it to improve livelihoods outcomes and enhance climate change mitigation.

This paper assesses the eco-efficiency of smallholder perennial cash crop production in Ghana and Kenya. It examines factors influencing eco-efficiency scores and in doing so, tests the application of order-m frontiers as a promising method for eco-efficiency analysis in the agricultural context. METHODS: The analysis is performed for four selected perennial crop cases, namely cocoa, coffee, macadamia, and mango, applying DEA as well as the order-m approach to a comprehensive empirical dataset. Seven relevant environmental pressures as well as determining factors around capacity development, farm and farmer features, and crop production environment are considered. RESULTS AND CONCLUSIONS:The distribution of eco-efficiency estimates among coffee farms showed the widest spread, which indicates the greatest potential to increase eco-efficiency. However, also the dispersion of scores within the other crop cases suggests room for improvements of eco-efficiency within the current production context. The subsequent analysis of determinants based on the order-m scores revealed that ecoefficiency scores were strongly influenced by variables, which measure capacity development, and resource endowments, such as labor and land, whereas the crop production environment had some influence, but results were unspecific. Generally, a positive effect is highly context-specific. The results underline the importance of designing effective training modalities and policies that allow knowledge to be put into practice, which involves the creation of marketing opportunities, the provision of targeted and regular advisory services, as well as regionwide measures to build and maintain soil fertility in a sustainable manner. SIGNIFICANCE: To our knowledge, this study presents the first attempt to apply inputoriented order-m frontiers to assess eco-efficiency in the agricultural context, comparing its eco-efficiency rankings to those estimated with the widely applied DEA approach. This can inform the discussion on robust eco-efficiency assessments.

Social sustainability is a work field characterised by an emphasis on social aspects, e.g. equity, ethics, health, gender balance, or empowerment, within a broader sustainability context. Although the concept seems to be reasonably well established and deemed worthy of pursuing, some obstacles prevent its wide dissemination. Through a bibliometric analysis focusing on the literature on social sustainability at institutions, with a focus on companies, this paper aims to investigate and describe some of the barriers associated with social sustainability implementation. Apart from identifying that sustainability reporting, environmental disclosure and financial performance play a central role in successfully achieving social sustainability, in the context of which gender-related issues seem more tangential, the results indicated some solutions commonly reported for overcoming barriers and obstacles to a company’s social sustainability implementation within different sectors. These solutions have to do, among many other factors addressed in this study, with strengthening communication transparency and trust, contributing to awareness, using technology to document and promote social sustainability. Thus, empowering organizations and citizens, recognized as essential factors to social development, and addressing the challenges in a multi-dimensional way.
