This book examines the impacts of global change on terrestrial ecosystems. Emphasis is placed on impacts of atmospheric, climate and land use change, and the book discusses the future challenges and the scientific frameworks to address them. Finally, the book explores fundamental new research developments and the need for stronger integration of natural and human dimensions in addressing the challenge of global change.
Biofuels Biofuels The use of biofuels is rapidly gaining momentum all over the world, and can be expected to have an ever increasing impact on the energy and agricultural sector in particular. Biofuels covers the use and conversion technologies of biomass as a renewable resource to produce bioenergy in a sustainable way, mainly in the form of liquid and gaseous biofuels. It gives a broad overview of biofuel developments from both a technical and an economical angle. The different production technologies for biofuels that exist or are under development are extensively covered in depth, dealing with both first generation as well as second generation technologies. Market developments in the sec...
“To begin evaluating an agricultural system, you’ll need to get to the core ideas and features that actually drive the system to ensure that you have a grounding for best methods and practices.” In his consulting career as an agronomist, and as a lifelong gardener, Scott Gillespie has learned to critically evaluate information before jumping into something new. Particularly in these days of climate-change anxiety, he has seen people choose agricultural systems that seem right on the surface but aren’t actually making a difference. Many times, a new idea is simply a good hypothesis. Early success can mean things get picked up quickly and are applied before they are fully tested. Pract...
Precision conservation is a reality, and we are moving towards improved effectiveness of conservation practices by accounting for temporal and spatial variability within and off field. This is the first book to cover the application of the principles of precision conservation to target conservation practices across fields and watersheds. It has clearly been established that the 21st century will present enormous challenges, from increased yield demands to climate change. Without improved conservation practices it will not be possible to ensure food security and conservation effectiveness. Readers will appreciate the application of the precision conservation concept to increase conservation effectiveness in a variety of contexts, with a focus on recent advances in technology, methods, and improved results. IN PRESS! This book is being published according to the “Just Published” model, with more chapters to be published online as they are completed.
In order to feed their burgeoning populations, developing nations will need to double cereal production by the year 2050. This increase will have to come from existing land, as little potential exists for bringing new land under cultivation -- a daunting prospect when one realizes that increased use and significantly higher concentrations of carbon
Brings scientists, policy makers, land and water managers and citizen stakeholders together to resolve natural resource and environmental problems.
