The methodology of construction of the alternative agricultural production scenarios at regional level includes profitability and feasibility analysis based on assessment the effect of global climate change on productivity parameters for the main agricultural crops, cost efficiency of crop...

The research was conducted for a representative 50 ha farm in the Onderberg region in Mpumalanga province, where farmers use a combination of centre-pivot, drip, and dragline systems of different sizes to grow sugarcane. The main intention was to establish a multi-period linear programming model...

This study used Rosen's methodology of deriving a marginal implicit price series from traditional hedonic modeling and then using this series to estimate a demand model. This procedure was applied to Kansas Hard Red Winter wheat protein. Results were mixed. Own-district protein level was not...

County-based group crop insurance is not effective to growers in counties with heterogenous production practice. A model-based cluster and classification method is developed to facilitate the information needed in the study of sub-county-zone-based crop insurance. Wheat yield data from Whitman,...

This paper develops and implements an import allocation model based on Theil's system-wide approach to demand and tests the assumption of blockwise dependence and uniform substitutability among different sources and types of wheat imported by Japan.

This study compares he profitability and risk related to conventional and organic vegetable production systems A linear programming model was used to find the optimal mix of vegetables in both production systems. And a target MOTAD (minimization of total absolute deviation) model was used to...

A spatial price equilibrium (SPE) model of the world sugar market is programmed. The model covers more than hundred regions and contains sugar in as a sole product. It has a detailed coverage of policies and bilateral trade agreements. It is programmed as a mixed complementarity problem (MCP) in...
