Traditional farming practice of rice field co-culture is a time-tested example of sustainable agriculture, which increases food productivity of arable land with few adverse environmental impacts. However, the small-scale farming practice needs to be adjusted for modern agricultural production. Screening of rice field co-culture farming models is important in deciding the suitable model for industry-wide promotion. In this study, we aim to find the optimal rice field co-culture farming models for large-scale application, based on the notion of food productivity.

Diversification has been increasingly recognized as a rewarding farm strategy through which farmers produce on-farm non-agricultural goods and services. In doing so, farmers employ farm inputs (capital, labor, and land) in products other than agricultural goods, with the aim to sell them in the market and increase their income. While a significant body of literature has explored the drivers affecting the adoption of diversification activities, so far little attention has been given to the impact of such adoption on the technical and financial performance of farms.

As rural poverty deepens over much of Sub-Saharan Africa, smallholder transformation has become more urgent than ever before. A majority of rural people derive their livelihoods from agriculture, hence the urgent need for transforming the sector. The South African government launched a comprehensive land reform programme at the dawn of democracy in the country on the assumption that constraints on land size would be eliminated to make room for a more inclusive agricultural economy.
