Allowing for Weather in Crop Production Model Building
1965
Oury, Bernard
Several alternative methods have been presented to measure weather effects upon crop production. This paper presents two more methods. These are the work of de Martonne and Ångström in the 1920's and 1930's applied to an econometric production model. The use of composite “aridity indexes” might provide a relatively simple approach to a difficult problem encountered in agricultural supply analysis. The concept is simple and is not confined to a single agricultural area or to a single crop. The indexes, both de Martonne's and Ångström's, can be calculated wherever basic weather data—precipitation and temperature—are available.
