Biodiversity is declining worldwide at an unprecedented scale and rate, with detrimental consequences on ecosystem functioning and services. Changes in land cover and agricultural intensification resulting from modern production systems pose extreme threats to biodiversity across scales and taxa . Extremely simplified landscapes with large fields of only a few crop species and where most semi-natural habitats were lost are widespread, which calls for a re-design of agricultural landscapes to enhance biodiversity [2,3]. To maintain the food production capacity that allows feeding the human population and to stop the ongoing biodiversity decline, immediate solutions are needed [4,5]. Ecologists and conservationists should provide evidence-based guidelines to stakeholders (from farmers to politicians) on how to ensure sustainable agricultural production.
Most likely, all the available tools, such us novel agricultural practices, efficient local conservation measures and sophisticated landscape planning, should be combined to achieve this goal. In this symposium, we propose a stimulating exchange of novel ideas among scientists, ranging from well-established group leaders (invited speakers) to early-carrier researchers (case study presentations). Furthermore, the symposium will also provide an opportunity to synthesize this information and facilitate the communication of relevant concepts and practices towards decision makers. The symposium will begin with a series of 8 invited lectures by established researchers, followed by 3 presentations of case studies focusing on measures to support biodiversity conservation in agricultural landscapes. The symposium will end with a panel discussion (ca. 45 minutes) where the different topics will be discussed and a summary from the different perspectives will be elaborated.
