Book Description
"A complementary forage rotation (CFR) aims to achieve high levels of home-grown forage to complement high performance dairy pastures. An economic evaluation of the CFR technology is undertaken by combining biophysical modelling with preliminary results from farm trials conducted at the University of Sydney?s Corstorphine Dairy. This data is applied to steady state whole farm budgets to compare four alternate or progressive scenarios that might be considered by farmers looking at the potential to increase farm productivity through their feeding system beyond a base farm scenario. A base scenario of a relatively well managed dairy farm in NSW, with 140 ha of milking area, stocked at 2.4 cows/ha, utilises about 12 t DM/ha/year under irrigation and produces more than 16,000 L/ha/year from 6,900 L/cow, achieves 0.9 per cent return on assets. A system with improved pasture management over the base scenario, utilising 15.6 t DM/ha/year and 1.3 t DM/cow/lactation of concentrates to achieve 6,900 L/cow obtains 3.4 per cent return on assets. A production system where pasture and supplement (concentrates) are emphasised achieves 6 per cent return on assets (3.7 cows/ha, 9,000L/cow and 2.3 t DM/cow/lactation concentrates). In comparison the CFS system obtains a return on total assets of 8 to 12 per cent, based upon actual or targeted (best case) forage yield results, respectively. The CFS-based farm business becomes relatively more profitable when scenarios with increased cost of fertiliser, water and especially grain are examined. A production system incorporating the complementary forage rotation (CFS) has the potential to be profitable. However, these analyses are based upon a steady state situation, after the implementation of the systems on farm, and implementation costs associated with adopting the technology on individual farms should be considered."--Abstract.

Book Description
In this how-to guide, ecologist and forest farmer Steve Gabriel explores the philosophy and techniques behind silvopasture - the integration of trees, animals, and forages in a whole-system approach that creates a number of benefits for livestock, farmers, and the environment. This system not only provides a sustainable farm income, but also holds the key to restoring land, building soil carbon, and creating climate resilience.--COVER.

Book Description
This is the first book to comprehensibly describe how technology has shaped society and the environment over the last 200 years. It will be useful for researchers, as a textbook for graduate students, for people engaged in long-term policy planning in industry and government, for environmental activists, and for the wider public interested in history, technology, or environmental issues.

Book Description
"While the energy sector is a primary target of efforts to arrest and reverse the growth of greenhouse gas emissions and lower the carbon footprint of development, it is also expected to be increasingly affected by unavoidable climate consequences from the damage already induced in the biosphere. Energy services and resources, as well as seasonal demand, will be increasingly affected by changing trends, increasing variability, greater extremes and large inter-annual variations in climate parameters in some regions. All evidence suggests that adaptation is not an optional add-on but an essential reckoning on par with other business risks. Existing energy infrastructure, new infrastructure and future planning need to consider emerging climate conditions and impacts on design, construction, operation, and maintenance. Integrated risk-based planning processes will be critical to address the climate change impacts and harmonize actions within and across sectors. Also, awareness, knowledge, and capacity impede mainstreaming of climate adaptation into the energy sector. However, the formal knowledge base is still nascent?information needs are complex and to a certain extent regionally and sector specific. This report provides an up-to-date compendium of what is known about weather variability and projected climate trends and their impacts on energy service provision and demand. It discusses emerging practices and tools for managing these impacts and integrating climate considerations into planning processes and operational practices in an environment of uncertainty. It focuses on energy sector adaptation, rather than mitigation which is not discussed in this report. This report draws largely on available scientific and peer-reviewed literature in the public domain and takes the perspective of the developing world to the extent possible."

Book Description
At the time of his death in 1950, Joseph Schumpeter was working on his monumental History of Economic Analysis. Unprecedented in scope, the book was to provide a complete history of economic theory from Ancient Greece to the end of the second world war. A major contribution to the history of ideas as well as to economics, History of Economic Analysis rapidly gained a reputation as a unique and classic work. As well being an economist, Schumpeter was a gifted mathematician, historian, philosopher and psychologist and this is reflected in the multi-disciplinary nature of his great endeavour. Topics addressed include the techniques of economic analysis, contemporaneous developments in other sciences and the sociology of economics. This inclusiveness extends to the periods and individuals who figure in the book. As well as dealing with all of the major economists from Adam Smith to Maynard Keynes, the book considers the economic writings of Plato and Aristotle, of the Medieval Scholastics and of the major European economists. Throughout, Schumpeter perceived economics as a human science and this is reflected in a volume which is lucid and insightful throughout.

Book Description
North American Agroforestry Explore the many benefits of alternative land-use systems with this incisive resource Humanity has become a victim of its own success. While we’ve managed to meet the needs—to one extent or another—of a large portion of the human population, we’ve often done so by ignoring the health of the natural environment we rely on to sustain our planet. And by deteriorating the quality of our air, water, and land, we’ve put into motion consequences we’ll be dealing with for generations. In the newly revised Third Edition of North American Agroforestry, an expert team of researchers delivers an authoritative and insightful exploration of an alternative land-use system that exploits the positive interactions between trees and crops when they are grown together and bridges the gap between production agriculture and natural resource management. This latest edition includes new material on urban food forests, as well as the air and soil quality benefits of agroforestry, agroforestry’s relevance in the Mexican context, and agroforestry training and education. The book also offers: A thorough introduction to the development of agroforestry as an integrated land use management strategy Comprehensive explorations of agroforestry nomenclature, concepts, and practices, as well as an agroecological foundation for temperate agroforestry Practical discussions of tree-crop interactions in temperate agroforestry, including in systems such as windbreak practices, silvopasture practices, and alley cropping practices In-depth examinations of vegetative environmental buffers for air and water quality benefits, agroforestry for wildlife habitat, agroforestry at the landscape level, and the impact of agroforestry on soil health Perfect for environmental scientists, natural resource professionals and ecologists, North American Agroforestry will also earn a place in the libraries of students and scholars of agricultural sciences interested in the potential benefits of agroforestry.
