FACCE-JPI and the ERA-NET SusCrop, in the framework of the European Research Area, decided to join forces to put in place a Call for research projects addressing agrobiodiversity, with the purposes of providing practical and policy-relevant knowledge on how agrobiodiversity can improve resilience of agroecosystems. Projects selected under this Call will contribute to sustainable crop production, particularly agro-diversification strategies tailored to different European agricultural systems, and especially targeting landscapes and cropping systems with low and/or moderate agro-biodiversity, higher negative impact on agrobiodiversity, or most at risk due to low resilience.
