- Description: Studies of projected agro-climatic variability on the productivity of smallholding farming livelihoods have been evaluated by indirect methods using simulation models on country or regional basis but few have been done at the community level. This study explores direct observation of the impact of soil and climate factors on crop and livestock livelihood systems in the three major agro-ecological zones of the Eastern Cape Province of South Africa. It also analyzed their influence on small farmers’ choices of agrarian livelihood activities and the lessons learned for the suitability of agro-ecologically integrated agriculture as part of agrarian and food security reforms needed among small farming households in rural communities of South Africa. The impact of soil and rainfall on the crop and livestock livelihood choices of smallholders in the three major agro-ecological zones were explored. A cross-sectional survey was carried out among 223 smallholding farming households during the harvesting period of rain-fed farming season. Data on household livelihood activities were processed in monetary terms and subjected to gross margin and cost/benefit analysis. Geographic information system (GIS) mapping and statistical analysis were used to determine the association of smallholder maize revenue with agro-climatic variation. The results indicated that crop-based activities performed better in the Grassland zone, while livestock activities performed better in the Savanna zone. Small farms in the Karoo can only productively engage in livestock production. The results also showed that farming activities that combined more vegetable crops yielded greater profits than other field crops. Furthermore, the results indicate that the mixed cropping method remains one of the strategies for breaking-even and risk-bearing effort used by the smallholder farmers considering its cost-sharing benefits. Geographical information system (GIS) mapping further indicates that smallholders’ farming activity was not only affected by soilclimatic factors but by their management skills as well. We recommend agroecologically adapted policies and incentives for agriculture-based livelihood activities and intensified mixing of cropping systems among the smallholder farming households in the study area.

- Description: This position paper is developed in the context of the Fundisa [Teaching] for Change teacher education programme (www.fundisaforchange.co.za), as well as the Sustainability Starts with Teachers programmes for teacher education (www. sustainabilityteachers.org/course). Fundisa for Change is a South African programme while Sustainability Starts with Teachers is a Southern Africa Development Community (SADC) programme for teacher educators. Both these programmes seek to enhance transformative environments and sustainability education processes in teacher education. They have a strategic focus on situated and transformative learning approaches for learners to learn to ‘know the world’ and practice ‘being in the world’. The real world provides the context for learning and assessment for learning, but not enough is known about assessment of such learning.

- Description: Pesticides are used indiscriminately all over the world to protect crops from pests and pathogens. If they are used in excess, they contaminate the soil and water bodies and negatively affect human health and the environment. However, bioremediation is the most viable option to deal with these pollutants, but it has certain limitations. Therefore, harnessing the role of microbial biosurfactants in pesticide remediation is a promising approach. Biosurfactants are the amphiphilic compounds that can help to increase the bioavailability of pesticides, and speeds up the bioremediation process. Biosurfactants lower the surface area and interfacial tension of immiscible fluids and boost the solubility and sorption of hydrophobic pesticide contaminants. They have the property of biodegradability, low toxicity, high selectivity, and broad action spectrum under extreme pH, temperature, and salinity conditions, as well as a low critical micelle concentration (CMC). All these factors can augment the process of pesticide remediation. Application of metagenomic and in-silico tools would help by rapidly characterizing pesticide degrading microorganisms at a taxonomic and functional level. A comprehensive review of the literature shows that the role of biosurfactants in the biological remediation of pesticides has received limited attention. Therefore, this article is intended to provide a detailed overview of the role of various biosurfactants in improving pesticide remediation as well as different methods used for the detection of microbial biosurfactants. Additionally, this article covers the role of advanced metagenomics tools in characterizing the biosurfactant producing pesticide degrading microbes from different environments.
