The GREENHOOD project pioneers a comprehensive approach to address the global challenge of unbalanced nutrient flows in

regional ecosystems. Operating across four European countries and one associated region, GREENHOOD focuses on re-balancing

nutrient flows and reducing N/P emissions through five key strategies: a) Participatory Approach: Engaging diverse stakeholders

through capacity building, governance labs, and cross-regional exchange activities to ensure inclusive decision-making. b) Estimation

of Maximum Allowable Nutrient Inputs: Utilizing optimized budgeting methodologies, including novel modeling tools and socioeconomic

data, to assess the impacts of new balancing practices. c) Demonstration of Effective Nutrient Management Strategies:

Leveraging insights from previous R&D experiences to develop and demonstrate solutions for nutrient excess prevention, reduction,

and recycling in key sectors such as agriculture, wastewater treatment, aquaculture, and forestry. d) Establishment of Regional

Nutrient Circular Economy Schemes: Creating schemes to close nutrient flow gaps between sectors like livestock-agriculture and

aquaculture-agriculture, evaluating the agronomic performance and market uptake of bio-based fertilizers and by-products. e)

Innovative Governance Measures: Showcasing governance measures to incentivize the adoption of nutrient-balancing solutions,

collaborating with regional administrators and supporting existing policies. GREENHOOD also emphasizes effective dissemination

and exploitation of results by collaborating with strategic initiatives like CCRI and Mission projects, as well as conducting regional

twinning programs. Through these efforts, GREENHOOD aims to pave the way for societies to operate within safe ecological

boundaries while meeting socioeconomic needs.
