Agricultural System Models in Field Research and Technology Transfer

Agricultural System Models in Field Research and Technology Transfer

Most books covering the use of computer models in agricultural management systems target only one or two types of models. There are few texts available that cover the subject of systems modeling comprehensively and that deal with various approaches, applications, evaluations, and uses for technology transfer.

Methods of Introducing System Models into Agricultural Research

Methods of Introducing System Models into Agricultural Research

Why model? Agricultural system models enhance and extend field research...to synthesize and examine experiment data and advance our knowledge faster, to extend current research in time to predict best management systems, and to prepare for climate-change effects on agriculture. The relevance of such models depends on their implementation. Methods of Introducing System Models into Agricultural Research is the ultimate handbook for field scientists and other model users in the proper methods of model use. Readers will learn parameter estimation, calibration, validation, and extension of experimental results to other weather conditions, soils, and climates. The proper methods are the key to realizing the great potential benefits of modeling an agricultural system. Experts cover the major models, with the synthesis of knowledge that is the hallmark of the Advances in Agricultural Systems Modeling series.

The Farmer's Decision

Balancing Economic Agriculture Production with Environmental Quality

The Farmer's Decision

Decision making to achieve a balance between the economic goals of producers and environmental quality benefits is complex. Most of the time we consider that the balance is skewed to one side or the other and that there are winners and losers. From the production perspective, the loser is the economic return in exchange for environmental quality while from the environmental perspective, the loser is the environment at the expense of agricultural production and increased inputs. In reality, there are opportunities within agriculture for a win-win situation; however, to explore the endless possibilities that constitute acceptable solutions is extremely difficult. Over the past few years there has been an increasing development of decision support tools that provide a framework that could be applied to agriculture. As I have worked with producers extensively over the past few years, it has become apparent that we could provide more information to the American producer that would help them evaluate different scenarios in their farming systems and evaluate potential alternatives through a combination of simulation tools and decision support systems. These are easy concepts to suggest, but more difficult to implement. As an effort to expand our understanding of the potential of decision support tools for economic and environmental balance, a proposal was made to the Organisation for Economic Co-operation and Development (OECD) in two theme areas. The outcome yielded an international workshop that assembled an international group of experts in decision support systems, simulation models, and agricultural production through industry, consultants, and producers. This group also addressed enhancing environmental quality in agricultural systems. ---Jerry L. Hatfield from Preface.
