Weeds have a strong impact on arable production, causing yield quantity and quality losses. Adequately controlling them is fundamental in arable cropping. However, weeds develop strategies to survive control. For decades, the dominating method to manage weeds was the use of chemical herbicides. Weeds becoming resistant against these chemical herbicides is an obvious and global reaction; together with undesired environmental consequences, this creates increasing pressure to overcome chemical herbicide use. Therefore, foreseeing weed management demands exploiting and evaluating novel methods to replace them. Since each single method will probably be less effective than chemical herbicides, systematic integration and upscaling on levels like fields, farms, cropping systems, landscapes and socio-economics is required in research. Agro-ecological management of weeds stands for this ambition.

This book is a collection of chapters concerning the use of biomass for the sustainable production of energy and chemicals–an important goal that will help decrease the production of greenhouse gases to help mitigate global warming, provide energy security in the face of dwindling petroleum reserves, improve balance of payment problems and spur local economic development. Clearly there are ways to save energy that need to be encouraged more. These include more use of energy sources such as, among others, manure in anaerobic digesters, waste wood in forests as fuel or feedstock for cellulosic ethanol, and conservation reserve program (CRP) land crops that are presently unused in the US. The...
Since their commercial introduction in 1996, genetically modified (GM) crops have been adopted by farmers around the world at impressive rates. In 2011, 180 million hectares of GM crops were cultivated by more than 15 million farmers in 29 countries. In the next decade, global adoption is expected to grow even faster as the research pipeline for new biotech traits and crops has increased almost fourfold in the last few years. The adoption of GM crops has led to increased productivity, while reducing pesticide use and the emissions of agricultural greenhouse gases, leading to broadly distributed economic benefits across the global food supply chain. Despite the rapid uptake of GM crops, the v...
New technologies are becoming available for managing glyphosate resistant (GR) weeds and reducing their spread. GR crop technology has revolutionized crop production in the developed world and the benefits are gradually spilling over to the developing world. In order to sustain an effective, environmentally safe herbicide such as glyphosate and the GR crop technology well in to the future, it is imperative that the issue of GR weeds be comprehensively understood. This book provides such an essential, up-to-date source of information on glyphosate resistance for researchers, extension workers, land managers, government personnel, and other decision makers. Provides comprehensive coverage of the intensely studied topic of glyphosate resistant (GR) in crops Details the development of glyphosate resistance and how to detect and manage the problem in crops Helps standardize global approaches to glyphosate resistance Encompasses interdisciplinary approaches in chemistry, weed science, biochemistry, plant physiology, plant biotechnology, genetics, ecology Includes a chapter on economic analysis of GR impact on crops
Authored by world-class scientists and scholars, The Handbook of Natural Resources, Second Edition, is an excellent reference for understanding the consequences of changing natural resources to the degradation of ecological integrity and the sustainability of life. Based on the content of the bestselling and CHOICE-awarded Encyclopedia of Natural Resources, this new edition demonstrates the major challenges that the society is facing for the sustainability of all well-being on the planet Earth. The experience, evidence, methods, and models used in studying natural resources are presented in six stand-alone volumes, arranged along the main systems of land, water, and air. It reviews state-of-...
