Many people believe that organic agriculture is a solution for various problems related to food production. Organic agriculture is supposed to produce healthier products, does not pollute the environment, improves the fertility of soils, saves fossil fuels and enables high biodiversity. This book has been written to provide scientifically based information on organic agriculture such as crop yields, food safety, nutrient use efficiency, leaching, long-term sustainability, greenhouse gas emissions and energy aspects. A number of scientists working with questions related to organic agriculture were invited to present the most recent research and to address critical issues. An unbiased selection of literature, facts rather than standpoints, and scientifically-based examinations instead of wishful thinking will help the reader be aware of difficulties involved with organic agriculture. Organic agriculture, which originates from philosophies of nature, has often outlined key goals to reach long-term sustainability but practical solutions are lacking. The central tasks of agriculture - to produce sufficient food of high quality without harmful effects on the environment - seem to be difficult to achieve through exclusively applying organic principles ruling out many valuable possibilities and solutions.

Das Bienenvolk übt eine starke Faszination auf den Menschen aus. Das gilt heute noch genauso wie in früheren Zeiten. Bilder und Schriften erzählen vom Mythos Bienenvolk, von der Auseinandersetzung mit diesem Himmelswesen und dem unschätzbaren Wert von Honig und Wachs. Durch das Bienensterben ist das Thema wieder vermehrt ins Zentrum des öffentlichen Bewusstseins gelangt.Aus Rudolf Steiners Ausführungen vor den Arbeitern am Goetheanum ist eine Vortragsfolge entstanden, die dem Wesen der Bienen gewidmet ist. Die Vorträge sind hier als Ganzes integriert, sie bilden das Gerüst dieses Buches. Um die Vorträge herum sind einige Themen der Vorträge aus heutiger Sicht kommentiert. Zu einem besseren Verständnis sind sie mit Passagen aus dem Gesamtwerk ergänzt worden. Die Faszination der Vorträge liegt in ihrer Vielschichtigkeit, eröffnen sie doch ganz neue, beeindruckende Zugänge zum Wesen der Bienen.

Sustainability rests on the principle that we must meet the needs of the present without compromising the ability of future generations to meet their own needs. Starving people in poor nations, obesity in rich nations, increasing food prices, on-going climate changes, increasing fuel and transportation costs, flaws of the global market, worldwide pesticide pollution, pest adaptation and resistance, loss of soil fertility and organic carbon, soil erosion, decreasing biodiversity, desertification, and so on. Despite unprecedented advances in sciences allowing to visit planets and disclose subatomic particles, serious terrestrial issues about food show clearly that conventional agriculture is not suited any longer to feed humans and to preserve ecosystems. Sustainable agriculture is an alternative for solving fundamental and applied issues related to food production in an ecological way. While conventional agriculture is driven almost solely by productivity and profit, sustainable agriculture integrates biological, chemical, physical, ecological, economic and social sciences in a comprehensive way to develop new farming practices that are safe and do not degrade our environment. In that respect, sustainable agriculture is not a classical and narrow science. Instead of solving problems using the classical painkiller approach that treats only negative impacts, sustainable agriculture treats problem sources. As most actual society issues are now intertwined, global, and fast-developing, sustainable agriculture will bring solutions to build a safer world. This book gathers review articles that analyze current agricultural issues and knowledge, then propose alternative solutions. It will therefore help all scientists, decision-makers, professors, farmers and politicians who wish to build a safe agriculture, energy and food system for future generations.
