The impact of intense annual crop production on natural resources under the threat of climate change has resulted in a global magnification of environmental degradation and biodiversity loss. A concept for mitigating such consequences is the development of perennial grain cropping systems. Kernza®, domesticated from Thinopyrum intermedium, is among the most advanced examples of recently developed perennial grain crops for food or forage production with established experimental sites across Europe. Informed by natural ecosystems, specially grasslands, such systems provide an excellent and innovative design to promote nature-based solutions (NBS) to mitigate agricultural disservices and to provide ecological, social and economic benefits (Theme #3 of the BiodivERsA BiodivClim Call). With a permanent soil cover, high total biomass production and deeper root systems, perennial grain crops provide fundamental advantages for climate change mitigation and adaptation. Perennial grain crops support highly structured and complex food webs, improving the functional diversity and the conditions for its conservation. However, there is only limited understanding of biodiversity effects, crop performance and ecosystem services resulting from these systems. The systemic research approach of NAPERDIV is founded on comparative analyses between established perennial versus annual grain cropping systems along a Pan-European gradient (Sweden, Belgium, France) with different agro-ecological and climatic conditions. With an inter-disciplinary and multi-sectoral network of researchers and stakeholders across Europe, NAPERDIV will analyze (a) the agronomic performance of Kernza® to assess and simulate its resilience against climate hazards, (b) the crop-associated microbiome and its functional benefits (growth promotion, disease suppression), (c) the resilience of the soil microbiome against drought under expected climate variability, and (d) the soil fauna, its benefits and indicator values for crop performance, system diversity and processes. The multiple and transnational impacts of the NAPERDIV outcomes on environment, policy, society and economy will support the EU to strengthen its role as world leader both in research and innovation: (1) NAPERDIV will contribute to a sustainable, nature-based agriculture with limited use of agro-chemicals and benefits for biodiversity and climate change adaptation/mitigation. (2) NAPERDIV will deliver a solid scientific knowledge baseline for on-going and prospective legislative frameworks of the EU for the development of innovative and future-proof solutions of agricultural production addressing environmental and climate objectives. (3) NAPERDIV will contribute to nutrition security and generates novel bio-economic opportunities with investment potentials. (4) NAPERDIV will network at a Pan-European scale securing in the long-run the maintenance of a cooperative and multi-disciplinary research platform within and across Europe.
