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 [1]. 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.
