Climate change is intensifying, threatening global food security with rising temperatures, emerging pests, and water scarcity. To tackle these challenges, it is essential to create strategies that assist in adapting agriculture and local crops to the changing climate conditions, thereby ensuring economic activity and food security. RESILCROPS proposes a more sustainable crop protection model by utilising biostimulants from natural sources, such as algae biomass and diverse microorganisms, which can protect crops from biotic and abiotic stresses, contributing to a circular economy. These sustainable solutions will not only safeguard agricultural productivity in Atlantic countries, but also contribute to a more circular and environmentally friendly agricultural system. By addressing these challenges faced by each region, RESILCROPS will empower the AA to adapt to the changing climate and ensure a secure and sustainable food supply for the future.
