| Inhalt | Short preview: Agroecology, sustainability and human wellbeing A main driving force of the ongoing 'global change' is agriculture. Starting about forty years ago, advances in agronomy - particularly in the fields of plant sciences and technology -, lead globally to a tremendous intensification of land use in agriculture. This so-called 'green revolution' had far reaching consequences. At first sight, it was a spectacular success as it allowed a rapid and huge increase in food, feed and fiber production - at a rate that initially exceeded the rate of human world population increase - and, thus, it was a great help in alleviating the 'world hunger' problem. However, it became more and more evident that the intensive land use practices adopted in the course of this green revolution - which are based on high inputs of external non-renewable resources - are not sustainable. Despite a continuing progress of the intensification, the per capita agricultural production actually started to decline in many parts of the world since about ten years. Moreover, the environmental problems resulting from the high-input land use aggravated at an alarming pace, particularly in developing countries - pollution with devastating effects on ecosystem services and human health, loss of soil fertility approaching desertification by erosion and salinization in many regions with previously fertile land and, distressingly, a staggering and unprecedented rate of extinction of animal and plant species and decline of biodiversity. Not surprisingly, therefore, substantially more effort in research heading for the urgent 'greener green-revolution' has been widely requested and presumably will become a top priority in life sciences in the near future. The following topics will be presented and discussed: 1. Status of the 'Global change' induced by the profound transformation of agriculture during the last few decades. 2. Success and failure of the 'Green Revolution', with a main focus on the advances in plant sciences that elicited this revolution (plant breeding, plant nutrition, crop protection and yield formation) and the implications for human well-being. 3. Ongoing research aiming at a 'Greener Green-Revolution' by developing more sustainable agricultural systems relying less on the high input of external, non-renewable resources by exploiting and enhancing the biotic, internal resources of agro-ecosystems such as soil fertility depending on symbiotic plant-microbe interactions, mutual facilitation of plants in biodiverse cropping systems with appropriate crop rotations, mixed cropping or agro-forestry, and the capability of many plants to tolerate abiotic and biotic stresses. |
