Third BioEcon Workshop May 22 – 25, 2003 Abstract Among the in-situ and ex-situ conservation options available to conserve crop genetic resources (CGRs), on-farm conservation has recently attracted massive attention from concerned organizations. To make this option operational, placing incentives and removal of perverse incentives are believed to be crucial so that landraces of no immediate int...

Arid and desert lands in terms of specific environmental characteristics such as low annual precipitation,sequential droughts, huge drop in ground water levels or the like, have always faced strict limitations in waterresources. In the shadow of these characteristics and many other factors, Water Price Index (WPI) is significantlyaffected. This study set out with the aim of identifying and dete...

abstract present study used translog cost function for determining break point of paddy farms. requested data set include inputs’ prices and quantities, and production amounts had been acquired from 500 rice farmers of guilan province at 2009. model used in this study is seemingly unrelated regressions (sur). the results showed that labor and pesticides had the highest and lowest share of produ...

This paper considers the specific role of information and communication technologies [ICT] in reducing transaction costs in agriculture by enabling timely and affordable communication. Segmenting transaction costs in to several components, the paper isolates the costs associated with information search as the specific costs that could be influenced through ICT. Analyzing the findings of a case ...

Rising energy costs have increased the cost of pumping to the point that many farmers are finding irrigation to be unprofitable or only marginally profitable. Fortunately, however, pumping costs are an item that farmers have some degree of control. Pumping costs often are higher than they need be for two reasons: 1.) more water is pumped than is necessary, and/or, 2.) the pumping plant operates...

Carp is one of the most widely cultivated warm water fish, which has been introduced into many countries. It is essential for the manager of a carp farm to know the production costs and their evolution, showing the main inputs on which the cost reduction is worth effort. In Iran, carp farming is mainly based on common carp, silver carp, grass carp, and bighead carp, which were often reared in p...

Timing nitrogen applications to the biological needs of a crop is an effective way to reduce nitrogen losses to the environment. However, this strategy may carry a production risk and conflict with farmers' economic objectives. A field-level production decision model was used to estimate on-farm costs associated with timing nitrogen applications for crop needs in Indiana. For a risk-neutral far...

Given the abundant straw resources in Northeast China and the huge external costs associated with fossil fuels, straw-based biomass power plants have emerged as a popular alternative to coal-fired power plants. The sustainability of these green alternatives depends on straw supply from farmers, yet little is known about their perceptions regarding such supply because of a lack of cooperation in...

In Sri Lanka, the majority of farmers are generally poor,and rely on subsistence agriculture. If these farmers can even partially be made responsive to market needs, as opposed to current household needs, they could cultivate at least some income generating crops, which if sustained, can reduce their poverty. However, high transaction costs associated with obtaining market information have cont...
