This book was released on 2013-03-09 with total page 492 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate variability has major impacts in many parts of the world, including Australia. Developments in understanding of the El Niño - Southern Oscillation Phenomenon have introduced some skill in seasonal to inter-annual climate forecasting. Can this skill be harnessed to advantage? Or do we just continue to observe these impacts? How does a decision-maker managing an agricultural or natural ecosystem modify decisions in response to a skillful, but imprecise, seasonal climate forecast? Using Australian experience as a basis, this book focuses on these questions in pursuing means to better manage climate risks. The state of the science in climate forecasting is reviewed before considering detailed examples of applications to: farm scale agricultural decisions (such as management of cropping and grazing systems); regional and national scale agricultural decisions (such as commodity trading and government policy); and natural systems (such as water resources, pests and diseases, and natural fauna). Many of the examples highlight the participatory and inter-disciplinary approach required among decision-makers, resource systems scientists/analysts, and climate scientists to bring about the effective applications. The experiences discussed provide valuable insights beyond the geographical and disciplinary focus of this book. The book is ideally suited to professionals and postgraduate students in ecology, agricultural climatology, environmental planning, and climate science.

Download or read book Simulation Of Beef Cattle Production Systems And Its Use In Economic Analysis written by Thomas H Spreen and published by CRC Press. This book was released on 2019-07-11 with total page 269 pages. Available in PDF, EPUB and Kindle. Book excerpt: Economic analysis of beef cattle production has been limited by the inability to fully describe the underlying production process. Except for confined feeding of cattle, beef cattle production is the process of growing cattle who consume forages. The animal and the forage possess attributes of both factors and products of production. The production of forage constitutes one production process, animal growth is another production process, and reproduction by female animals is a third production process. Cattle production involves all three processes in such a manner that each influences the outcome of the other. Each process is itself complex and analysis is further complicated when all three are considered simultaneously.

Download or read book The Development of a Modeling Platform to Examine Management Alternatives to Improve the Sustainability of Beef Production written by Robin Rosemarie White and published by . This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this research was to develop a modeling platform to test the effects of management practices on sustainability of beef production systems. A simulation model was constructed to examine the role of improved efficiency on environmental impact (land use, water use and greenhouse gas emissions; EI) of beef production systems while increasing economic viability and consumer willingness to pay (WTP). An optimizer was developed to adjust cattle diets to minimize whole-system EI while constraining production costs within the bounds of consumer WTP. Cradle-to-farmgate EI and production costs were calculated following the simulation model. Consumer WTP for environmental attributes of beef was determined by meta-regression of published estimates of consumer WTP. The validated model was then used to assess how nutritional, reproductive and genetic management could help improve sustainability. Nutritional management alone reduced EI by 2%. Twinning or decreasing the calving window decreased EI by 17% or 11%. Selected bulls by expected progeny difference reduced EI by 18%-19%. Finally, Bayesian analysis was used to quantitatively summarize consumer WTP for environmental attributes of meat. The model predicted U.S. consumers WTP ranged from 6.7% to 32.6%. The confidence range was used to predict probability of consumer purchase across the schedule of WTP. When probability of purchase was ignored, this range in WTP equated to a maximum 65.5 L/kg beef reduction in water use when beef cattle diets were adjusted. When probability of purchase was factored in, a 10% increase in WTP optimized theoretical opportunity to decrease EI, netting a 41.4 L/kg beef reduction in water use. A novel model was successfully developed and used to assess the role of specific management practices and their use in improving beef production sustainability. Optimizing nutritional management, including reliance on precision pasture management, while concurrently improving genetic and reproductive efficiency, substantially improved sustainability. Additionally, when relying on WTP as a method of incentivizing adoption of environmental-impact reducing management practices, focus should be put on obtaining market share rather than sacrificing cost in an attempt to reach the biological ideal opportunity to minimize environmental impact.

Download or read book Modelling Applications to Pasture based Beef Production in Atlantic Canada written by Katherine Anne Benedict and published by . This book was released on 1999 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: A system model of a pasture-related beef production, entitled the Atlantic Pasture Based Beef Model (APBM), was developed and evaluated for Atlantic Canada. The model was used to examine the effects of calving season (winter or spring) and pasture type (naturalized or improved) on the animal output in calf gain (kg). The plant component, a timothy (Phelum pratense ) production model, simulates, on a daily time step, metabolizable energy (ME), crude protein, and biomass accumulation from environmental inputs. The animal component utilizes the ME output of the plant to satisfy energy requirements for maintenance, growth, and production. Finally, the environmental inputs were generated by a weather component that was based on the Canada Climate Normals for Truro, Nova Scotia. The individual component models and the system model were evaluated through verification, calibration, and validation using data collected from beef research and farm systems in Atlantic Canada. The calibration of the plant component was completed using the data from years of research trials at Nappan, Fredericton, Charlottetown, and Truro. The animal component was calibrated based on the chosen breed of cattle (Hereford or Hereford cross).
