Résumé
The aim of a biofactory is to empower the local development of agriculture. To get an overview of such infrastructures, a non-exhaustive inventory has been drawn up in Latin America, sub-Saharan Africa, and Asia, using literature, websites, and contacts. They vary widely in size, from individual production of bioinputs to village communities trained by Paysans Relais (in Madagascar), University structure, and crop-protection firm-type entities. The bioinputs produced, given or marketed to smallholders, are mainly organic fertilizers (compost-based biofertilizers such as 'Bokashi'), substitutes for synthetic pesticides such as plant-based preparations, and microbial solutions (e.g., biostimulants). Beneficiaries often practice organic or agroecological farming. To help set up a biofactory, guides and videos are available. Diverse factors influence the adoption or rejection of the produced bioinputs. Among the constraints to be overcome before a biofactory can be truly deployed are the availability of technical and plant materials, the time required to prepare and store bioinputs, their effectiveness in relation to their application frequency (for botanical extracts), and the product cost when marketed. A main important factor for their implementation is their promotion by institutions, governments (as in Colombia), and organizations (e.g., ESSOR, Ethiquable) some being non-profit. Research is called upon at every stage to validate the bioinput value chain.
