Small can be beautiful for organic market gardens: an exploration of the economic viability of French microfarms using MERLIN

This study shows that organic microfarms can be made economically viable in some cases but that the risks of not reaching viability in microfarms are not to be neglected. For microfarms, system redesign based on low mechanization, higher cropping density, more cropping cycles per year, low-input practices, lower fixed costs, and lower initial investment (manual and bio-intensive system with tiller cultivation) was more favorable (meaning a higher modeled viability) than input substitution (classic system) at a small scale. A 9-month selling period without winter storage crop cultivation led to higher viability than a 12-month selling period with winter storage crop cultivation. Low-cost investment strategies based on self-built equipment and second-hand materials led to lower viability than high-cost investment strategies that purchased equipment because the low-cost strategies increased the workload. Further research on microfarms should integrate other types of production and activities, such as small-scale breeding and on-farm processing and examine in which extent collaborations between microfarmers and larger scale farms could contribute to reshape farming systems and impact rural communities beyond the gate of microfarms.
