Sustainable food systems through diversification and indigenous vegetables

The performance of the food system in the southern Nakuru County is currently poor in terms of economic, social and environmental sustainability. The booming flower and vegetable export sectors and the strong market position of a few staple crops leave little room and incentives for smallholders to invest in improved and more diversified production and productivity. Deforestation and decreasing soil and water quality due to intensive production systems and large commercial farms have a visible impact on the environment. Our multidisciplinary research shows that the weaknesses of the three types of sustainability reinforce one another, making economic, social and environmental threats interconnected.

One way to improve the sustainability of the local food system is diversification, starting with better integrating indigenous vegetables, such as spider plant or black nightshade, into the food system. These hold many benefits: they are nutritious, require low natural resources and farming inputs, and can contribute to climate resilience.

But how feasible is the transition to a more sustainable food system in Nakuru? The importance of diversified systems is already reflected in a number of policies, but implementation is poor. Local institutions such as farmers’ organisations that could stimulate a more diversified food system are very weak, and governance bottlenecks create a particular ‘system bias’ against indigenous vegetables.

However, a number of entry-points for change exist in the food system. The Ministry of Agriculture could issue a regulation for blending maize and indigenous crop flours, which would lead to more demand and production for indigenous vegetables. Other options include improving the legislative framework to favour indigenous vegetables’ seeds. Creating a multi-dimensional sustainability label for indigenous vegetables to draw consumers’ awareness is another promising pathway to support a transition from export-oriented monocultural agri-landscapes towards a more diversified food economy primarily targeting Kenyan markets.

I agree with the third pathway of creating a multidimensional sustainability label for indigenous vegetables. There is increased concern over the production sites and husbandry of these vegetables by a segment of the consumers.

While I strongly support the idea of crop diversification, I think it is very helpful to share with you the observations on diversification I have made in Zimbabwe. Although this is not directly related to your project, I believe it is worth sharing. Farmers who are pursuing food crop diversification are actually producing very poor yields at low quality levels. There is a possibility that there desire to diversify lead them to spread very thin resources across many crops, with the effect manifesting in low output levels. I therefore, have a feeling that diversification drive should be made with a concomitant emphasis on raising the current productivity levels. Output per unit of land should be increased at the same time with diversification.
