Circular economy interventions in four key sectors can halt global biodiversity loss and help the world's biodiversity recover, finds this study.

Tackling root causes - Halting biodiversity loss through the circular economy, written by experts from Sitra and Vivid Economics, is the first to quantify the role a circular economy can play in tackling global biodiversity loss, targeting the four sectors with the largest impacts:

• food and agriculture
• construction
• textiles
• forest and forestry

Circular interventions in these sectors can halt biodiversity loss even if no other action is taken. And more than that, the study finds that the world’s biodiversity can recover to 2000 levels by 2035, if the circular interventions are implemented.

Urban agriculture comes with its own share of environmental impacts. Circular strategies promise to reduce these impacts, but not all strategies are resource efficient and environmentally effective.

This paper finds that the most eco-friendly and circular strategies for urban agriculture, taking a Mediterranean tomato crop as a case study, include:

• Struvite (phosphate mineral recovered from wastewater treatment) instead of non-renewable phosphate fertiliser to conserve freshwater
• Recycled steel and materials for urban agricultural infrastructure to reduce carbon emissions, toxicity and freshwater pollution
• Closed-loop irrigation to minimise ocean and freshwater pollution. However, if new infrastructure is required, it could lead to an increase in carbon emissions.

Commissioned by the Scientific and Technical Advisory Panel (STAP), which advises the Global Environment Facility (GEF), and co-authored by Circle Economy and Shifting Paradigms, this report uncovers the range of socio-economic and environmental co-benefits that circular mitigation interventions can bring to GEF countries of operation.

The report supports strategic advice by the STAP to the GEF and its implementing partners, and helps carve out a role for these bodies in accelerating the transition to a low-carbon circular economy. Its findings will be highly relevant to the development of future GEF projects and programmes across its different focal areas.

The third of the four Thematic Working Groups created by the Interreg MED's Green Growth community addressed waste reduction, prevention and management.

This White Paper promotes solutions to reduce organic (livestock) and inorganic waste, and maps technologies, systems, and strategies for proper waste management. It illustrates issues - e.g. over-production/application of high-nitrogen slurry and manure and need to treat it, as well as lack of treatment of agrifood waste - and highlights the projects’ contributions to achieve full use of resources through their life cycle to create a circular economy.

Among the results: policy guidelines based on four Struvite Precipitation (SP) plants to stimulate innovation and set up a common legal framework for struvite as fertilizer.
