Supply productivity and timber industrialization in Aboreachi ejido, Guachochi, Chihuahua State

Abstract

The objective of this research was to evaluate the productive evolution of a decade of timber supply, industrialization and commercialization in the Aboreachi ejido, Guachochi, Chihuahua. In this work, 10 annuities of timber harvesting were considered, from January 2010 to December 2019, 9 327 remissions of round wood and 2 040 reshipments of sawn wood were analyzed. The Shapiro-Wilks test was used to determine the normality of the observations; the homogeneity of the variances was determined with the Levene test; Kruskal-Wallis tests were carried out to evaluate the productivity of the annuities; and Pearson correlation analyzes were carried out to evaluate the increase in freight rates as a function of the authorized volume. All statistics were performed at a significance level α=0.05. Logging with draft animals increases jobs, but limits supply productivity in conjunction with the quality of vehicles. An increase in the number of shipments of round and sawn wood was found in relation to the increase in authorized volume (r=0.775 and 0.495 respectively). The Kruskal-Wallis analysis shows that the differences in round wood supply flows and supply expenditures were significant (α<0.05). On the other hand, the transport of sawn wood, processing expenses and sales income show significant differences (α<0.05) between annuities. The industrial technological renovation managed to increase the volumetric yield of sawn wood by 9.45 % and consequently the productivity of the Aboreachi ejido.
