While Asian food economy has been experiencing significant transitions, little transformation occurs in farm land operation. However, recent rapid emergence of middle and large farms in many regions of China is striking. Overall goal of this paper is to understand small-scale farm transformation in China based on a unique dataset surveyed in Northeast and North China. The results show that the ...

The simulation program developed by the "Models Of Networked Analysis at Regional Centers" (MONARC) project is a powerful and flexible tool for simulating the behavior of large scale distributed computing systems. In this study, we further validate this simulation tool in a large-scale distributed farm computing system. We also report the usage of this simulation tool to identify the bottleneck...

The structural transformation of agriculture in recent decades has raised serious concerns about the future of the family farm. This study examines the economic performance of U.S. farms, to explore the potential of smaller farms to compete with larger entities, and ultimately to survive in this rapidly changing environment. We use deterministic and stochastic frontier methods and survey data t...

In this paper we introduce Farm, a distributed simulation environment for simulating large-scale multi-agent systems. Farm uses a component-based architecture, allowing the simulation to be easily modified and augmented, as well as distributed to spread the computational load and improve running time. Technical details of Farm’s architecture are described, along with discussion of the rationale...

Land use and management change is a feature of New Zealand farm systems, driven by a range of factors including volatile markets and exchange rates, variable weather and climate patterns, continuous policy evolution and the inherent innovation of New Zealand farmers. Yet the common indicators used to evaluate the impact of change appear to be limited to the link between productivity (of land/la...

ARE LARGE FARMS MORE EFFICIENT? Accurate estimates of returns to scale require that inputs and output are measured without error and that environmental and managerial differences among firms of varying sizes are taken into account. Measurement problems affecting estimates of returns to scale in agriculture include: (1) combining the farm dwelling with capital inputs, (2) correlation of environm...

Introduction Measures of farm diversification Data and model specification Econometric results Discussion Summary and conclusions Acknowledgements References Appendix Abstract. Farm planning often focuses on optimal diversification with respect to risk, where the riskmanagement strategies combine production, marketing, financial and environmental aspects of the farmfirm. In this study an empiri...

Government agricultural programs have a variety of goals, among them is preserving the family farm (U.S. Department of Agriculture 2003, pp. 18–20). While no single program is dedicated to maintaining a certain type of farm structure, program features are sometimes designed so as not to disadvantage family farms. For example, dollar limits may be placed on payments that a single person can rece...

Abstract: The application of large scale energy storage makes wind farms more dispatchable, which lowers operating risks to the grid from interconnected large scale wind farms. In order to make full use of the flexibility and controllability of energy storage to improve the schedulability of wind farms, this paper presents a rolling and dispatching control strategy with a battery energy storage...
