Project description
Prospective scenarios for nutrient recovery in agri-food systems
Conventional agricultural practices rely on synthetic fertilisers. Nutrients extracted during harvests are seldom brought back to the soil. After ingestion by humans, nutrients are excreted in urine and fecal matter that are seldom recovered as fertilisers. This system has caused extended social and environmental costs that are aggravated by predominantly animal-based diets in wealthy countries. Source separation and recovery of urban organic matter (human excreta, kitchen and green waste) as fertiliser and amendment could make agri-food ecosystems sustainable. The Marie Skłodowska-Curie Actions CAFE project will develop prospective scenarios for nutrient recovery and assess pathways towards circularity. The project will use complex networks and methods converting and analysing existing data sets to generate logistics networks relevant to these scenarios.
Objective
"In current ""conventional"" agricultural practices, most farmers depend on synthetic fertilizers and nutrients extracted during harvests are seldom brought back to the soil. This open-circuit organization of food systems induces the prospect of phosphate shortage and consumes large amounts of abiotic resources and energy to generate fertilizers or process nutrients once they end up in sewage. Such a linear and extractive system, together with current fertilizer application methods, has incurred great social and environmental costs around the world, leading to significant biodiversity loss, soil erosion and salinisation as well as nutrient leaching. Finally, animal-based diets in the largest economies further increase the pressure on food systems as feeding animals inflates land and nutrient use.
Source separation of organic matter and its recovery are likely to be critical for the long-term sustainability of the agri-food and waste-management systems in an increasingly urban world. Indeed, the transformation of kitchen or green waste and human excreta can provide invaluable resources such as compost, fertilizers, or energy and eventually remove the need for synthetic fertilizers.
This project will develop prospective scenarios for nutrient recovery and assess how far they can bring the agri-food system on the path to circularity. Using complex networks and systems methods, we will convert and analyze existing datasets to generate logistics networks associated to these scenarios. These networks will model the fluxes of organic matter between sources (habitations), processing or storage locations, and sinks (parcels). We will also assess the impact of dietary changes and low-fertilizer or agro-ecological practices compared to business-as-usual situations. This will enable us to evaluate the technical feasibility of these recovery scenarios and quantify how much they improve agri-food sustainability and can help local actors tackle their socio-ecological transition."
