The present Atlas of Biodiversity Risk is the first of its kind todescribe and summarise in a comprehensive, easy-to-read and richlyillustrated form the major pressures, impacts and risks of biodiversityloss at a global level. The main risks identified are caused by globalclimate and land use change, environmental pollution, loss ofpollinators and biological invasions. The impacts and consequences ofbiodiversity loss are analyzed with a strong focus on socio-economicdrivers and their effects on society. Three scenarios of potentialfutures are the baseline for predicting impacts and explore options formitigating adverse effects at several spatio-temporal scales. Elementsof these futures are modeled, tested and illustrated. The Atlas isdivided into chapters which mostly deal with particular pressures. Itfurthermore is based on case studies from a large set of countries,which are completed by introductory and concluding texts for eachchapter. The Atlas combines the main outcomes of the large Europeanproject ALARM (performed by 68 partner organisations from 35 countriesfrom Europe as well as other continents) with some core outputs ofnumerous further research networks. A total number of 366 authors frommore than 180 institutions in 43 countries provided information andcontributed to the Atlas. The Atlas is addressed to a wide spectrum of users. Scientists will findsummaries of well-described methods, approaches and case studies.Conservationists and policy makers will use the conclusions andrecommendations based on academic research output and presented in acomprehensive and easy-to-read way. Lecturers and teachers will findgood examples to illustrate the main challenges in our century of globalenvironmental changes. The Atlas is an indispensible tool to anylibrary or institution in biodiversity and environmental sciences.Finally, all people concerned with environmental issues will find theAtlas a powerful weapon in their fight for saving the life on ourPlanet!
