Bio-based Solutions

Our vision is to contribute to sustainable livelihoods in rural areas of Africa, through domestic agri-food systems which can sustain growing populations in an inclusive and environmentally friendly way in the long term. DIVAGRI increases the productivity of the African agri-food systems, connects supply to demand and turn wastes into resources through connected value networks within the bioeconomy through selected enabling bio-based solutions tailored to specific conditions in the five target countries.

DIVAGRI has screened existing bio-based solutions and selected a set of technologies that (a) have the potential to help tackle the specific technological, social and economic barriers identified in target countries, (b) can be applied to all scales, are easy to operate, robust and easy to maintain, (c) are compatible with existing sustainable agricultural practices, and can be widely replicate across a diversity of productive conditions in which they will be applied, and (d) cover all stages of the agri-food value chain: supply of farming inputs, primary production (farming), product transformation, and marketing & distribution.

Each of these technologies produces or enhances quality and quantity of farming inputs, quality, quantity and diversity of food production, and/or enables the production of new bio-based end-products from otherwise unused resources (by-products and waste). Three technologies (biochar, biogas, biorefineries) can be stationary or mobile, opening new opportunities for dissemination and cooperative business models. Selected bio-based solutions include restorative and diverse crop production systems, integrated mobile biorefineries, adapted biochar and biogas processes to valorise a wide range of farming residues, the highly innovative clay-based   micro-irrigation   system   “SLECI”,   vegetation-enhanced   solar   desalination   greenhouses   and multifunctional constructed wetlands.
