El agro colombiano en píxeles: nuevos aportes a la relación inversa tamaño-productividad

Empirically it has been found that small plots produce more per hectare than large ones. Bevis & Barrett (2020) explain this inverse relationship between farm size and productivity per unit of land through the perimeter-area ratio, which reflects the possible existence of higher productivity on the periphery of the plots or border effect . Based on these findings, this research builds a database using satellite images that proves the existence of the edge effect and examines its possible impact on the size-productivity relationship. Thus, using a pixel-plot panel and a yield proxy, it was found that the edge effect was significant in a sample of cotton plots located in Córdoba (Colombia) for 2013. In addition, with data added by plot, it was estimated that the size-productivity (biophysical) relationship was direct, and that it lost significance if the average between the sum of the distances of each pixel to the edge of the plot was included.
