INRA has published a four-year study on the economic viability of organic permaculture. This study entitled "Permacultural Biological Mariculture and Economic Performance" shows that permaculture can be quite economically competitive with conventional intensive farming. The study was carried out on a rather small area of 1000m², ie 1 / 10 of hectare, and with a good proportion in forcing (greenhouse), it follows that each m² cultivated in organic permaculture can generate a turnover exceeding 50 € / m² for direct sale.
What motivated some to start their garden permaculture, it is good because on econology, we have developed a cultivation technique even more powerful than the biological permaculture: the Kitchen Garden Sloth (no fertilizer or pesticide, even organic)
Farm Bec Hellouin
Economic study of a plot type 1000 m2 within the farm BEC HELLOUIN (2011-2015). Researcher contact: François Léger, UMR INRA AgroParisTech SAD-APT.
Presentation of the study
The Organic Farm Bec Hellouin develops 2007 from a model of original gardening, combining space organization inspired permaculture and techniques
gardening biointensif (E. Coleman, J. Jeavons, etc.). Very little mechanized, on a very small acreage, set to short circuits, this model creates a very strong interest.
But is it economically viable? It is to this question that the study conducted by the farm, the Sylva Institute and the SADAPT research unit (INRA-AgroParisTech) intended to respond. The peculiarity of this study is to be conducted on a farm where techniques, tools, new marketing methods are constantly tried, far from the "routine operations" which generally serve as a support for the production of technical references. economic.
From December to March 2011 2015, gardeners have systematically noted their interventions (nature of these, working time, inputs, etc.) and quantified crops grown on a surface of boards 1000 m², outside walkways and approaches, including 42% greenhouse. Note that these 1000 studied m2 match the most intensive area of the farm Bec Hellouin and should in no way be considered sufficient to establish a microferme. Indeed, in a permaculture logic, very neat surface is part of a broader package that includes less intensive areas (to produce crops with long cycles such as vegetables of winter storage), natural areas and buildings required for good ecological and commercial operation of the assembly.
