The declining availability of irrigation water from the Ogallala aquifer combined with increasing energy costs make irrigation strategies much more critical. Maximizing yield reduces profit by between $22 and $158 per acre depending on the combination of corn and natural gas prices.

This paper uses data collected in an extensive survey of farm costs in the Dong Nai River Basin of Vietnam to estimate the parameters of production functions for rice, vegetables, and coffee. These estimates are then combined with price information to estimate marginal value products for...

Waterlogging and salinisation have contributed to the demise of ancient civilisations and continue to threaten the sustainability of irrigated agriculture today. This paper evaluates the adoption of higher efficiency irrigation systems as an alternative for reducing the impact of waterlogging...

Due to declining water availability from the Ogallala Aquifer and increasing pumping costs, irrigation management options for cotton are analyzed. The study concludes that supplemental irrigation while meeting crop ET requirements is the most profitable option. Switching from corn to cotton...

Waterlogging and salinisation have contributed to the demise of ancient civilisations and continue to threaten the sustainability of irrigated agriculture today. This paper evaluates the adoption of higher efficiency irrigation systems as an alternative for reducing the impact of waterlogging...

We use the new version of the GTAP-W model to analyze the economy-wide impacts of enhanced irrigation efficiency. The new production structure of the model, which introduces a differentiation between rainfed and irrigated crops, allows a better understanding of the use of water resources in...

Encouraging the use of more efficient irrigation technology is often viewed as an effective, politically feasible method to reduce the consumptive use of water for agricultural production. Despite its pervasive recommendation, it is not clear that increasing irrigation efficiency will lead to...
