Paul Corral (American University) Most endogenous sample selection issues have been dealt with variants of Heckman's selection model. The model relies on the assumption of normality. However, when dealing with data where the data generating process is unknown, and the data may be less than ideal an information theoretic approach may be more suitable. During the summer I have been working on imp...

Data Farming is a process that has been developed to support decision-makers by answering questions that are not currently addressed. Data farming uses an inter-disciplinary approach that includes modeling and simulation, high performance computing, and statistical analysis to examine questions of interest with a large number of alternatives. Data farming allows for the examination of uncertain...

This paper conducts an empirical study on output, costs and incomes in organic farming with a sample of Spanish firms. Financial accounting data reveals that organic and partly or transitional to organic farming do not get significantly different output than intensive farming. Farms in transition to organic farming bear significantly higher costs and obtain significantly lower income than inten...

gies borne of the information age with a mature agricultural industry. It is an integrated crop management system that attempts to match the kind and amount of inputs with the actual crop needs for small areas within a farm field. This goal is not new, but new technologies now available allow the concept of precision agriculture to be realized in a practical production setting. Precision agricu...

While organic farming is well established in Europe a nd USA, it is still catching up in Asian countries. The government of South Korea has implemented environmentally friendly farming that encompasses organic farming. Despite the promotion of environmentally friendly farming, it still has a low share in South Korea and partially converted farming has emerged in some districts of South Korea. H...

This paper presents an approach to select the best farming strategy considering various criteria. The goal is to help a farmer to take appropriate decision in farming. Two possible alternatives are consideredConventional farming and Organic farming. These farming types are evaluated by MCDM technique taking into account three criteria viz. Productivity, Marketing, and Health-Environment Friendl...

A newly developed low cost system for fish-farm wastewater treatment was evaluated. The system consisted two major parts: (1) a new type of square tank design with two separate outlets, i.e. one centrally positioned high solids concentration outlet and one corner located low solids concentration primary outlet; and (2) a stationary bowed screen for solid removal from the high solids effluent. R...

Ever increasing attention is being paid to the environmental impact of intensive agricultural practices, and in this context organic farming is gaining recognition as a relatively friendly production system. In general, the risk of harmful environmental effects is lower with organic than with conventional farming methods, though not necessarily so. This review examines organic farming in the li...
