Pages : 283
Book Description
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.

The Economics Of Livestock Systems In Developing Countries
Author: James R SimpsonPublisher: CRC Press
ISBN: 100031622X
Category : Science
Languages : en
Pages : 324
Book Description
Improvement of the world's livestock industry necessitates input from many directions. Planning by a host of national and international agencies is required in order to provide optimal stimulus in very diverse areas ranging from formulation of laws and incentives that stimulate competition yet prevent undue competition, to the optimal provision of credit. Planning is needed to carry out a complex array of interrelated research. The purpose of this book is specifically tasked with setting forth frameworks and methods for evaluation of investments and associated economic decision-making in the livestock industries of developing countries. Economists will find this book useful because it synthesizes .much material into a cohesive whole--material that is often presented in a cursory manner or overlooked as emphasis has shifted to sophisticated quantitative techniques.
Applications of Seasonal Climate Forecasting in Agricultural and Natural Ecosystems
Author: Graeme L. HammerPublisher: Springer Science & Business Media
ISBN: 9401593515
Category : Science
Languages : en
Pages : 492
Book Description
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.
