Studies of projected agro-climatic variability on the productivity of small-holding 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 small-holders in the three major agro-ecological zones were explored. A cross-sectional survey was carried out among 223 small-holding 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 small-holder 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 small-holder farmers considering its cost-sharing benefits. Geographical information system (GIS) mapping further indicates that small-holders’ farming activity was not only affected by soil-climatic factors but by their management skills as well. We recommend agro-ecologically adapted policies and incentives for agriculture-based livelihood activities and intensified mixing of cropping systems among the small-holder farming households in the study area.
