FrontAg Nexus research highlights that accelerating frontier agriculture adoption necessitates targeted policy interventions and a strategic approach to enhancing readiness levels. Coherent policy frameworks, specific incentives, and robust R&D support are crucial to bridge the gap between technical feasibility, business readiness, social readiness (TRL, BRL, SRL), and practical implementation.
Findings from the FrontAg Nexus project’s systematic literature review and value chain analyses underscore the critical importance of implementing socially responsible practices, ensuring fair labour conditions, promoting gender equality, and actively engaging local communities in the development and deployment of frontier agriculture systems. This integrated approach fosters a just transition that benefits all stakeholders.
The FrontAg Nexus project highlights advanced hydroponic systems as a climate-smart solution. These soilless cultivation methods offer precise control over nutrient delivery and water use, enabling significant resource optimization. Adopting closed-loop hydroponic systems, especially when integrated with renewable energy and alternative water sources (like desalinated water), enhances sustainability and circularity.
The interdependence of water, energy, food, and ecosystems (WEFE Nexus) is severely challenged by water scarcity in the Mediterranean, necessitating innovative agricultural solutions. Traditional farming
The FrontAg Nexus project’s experience at ElBosten Phytagri highlights complexities in manual cross-pollination for self-incompatible pitaya (‘White from Mexico’) using a self-fertile variety (‘White from Vietnam’). Initial trials, while challenging, underscored the critical need for a deeper understanding of varietal compatibility, climatic impacts, and greenhouse environmental effects on pollen viability.
The FrontAg Nexus project showcases ElBosten Phytagri’s adapted pitaya cultivation under greenhouse cover, highlighting customized, low-input irrigation and fertilization practices. This approach optimizes water and nutrient delivery, efficiently utilizing the plant’s shallow root system for quality production.
Vertical farming offers a sustainable solution for urban food production, but energy optimization remains a critical challenge, with nearly half of the electricity requirements dedicated to artificial lighting. Dynamic adjustment of blue and red light can reduce energy costs, as blue light is more energy-intensive, thereby lowering operating expenses and increasing profitability.
This resolution captures the key outcomes of the WEFE Nexus Solutions & Tools Workshop (Chania, March 2026), outlining challenges, priorities, and actionable pathways for advancing integrated Water–Energy–Food–Ecosystems approaches.
The Water-Energy-Food-Ecosystem (WEFE) Nexus has evolved from a resource efficiency paradigm within water, energy, and food (WEF) systems toward a broader governance framework that recognizes ecosystems as essential to resource security and sustainability.
EU funding increasingly prioritises research addressing complex agri-environmental challenges, such as soil degradation, biodiversity loss, and water scarcity, especially in the EURO-Mediterranean region, known as a climate change hotspot.
