Environmental analysis of land use changes in the district of Azul (Buenos Aires, Argentina)

Ever since transgenic soybean crops began to spread in the mid-90s, agricultural lands have expanded remarkably in Argentina, thus producing changes in the dominance of major crops and bringing about various environmental consequences. This work aims to analyze changes in the use of lands in Azul, a...

Zulaica, L. Requesens, E. Agriculturización sensores remotos paisajes impactos ambientales. Agriculturization remote sensing landscapes environmental impacts. Ever since transgenic soybean crops began to spread in the mid-90s, agricultural lands have expanded remarkably in Argentina, thus producing changes in the dominance of major crops and bringing about various environmental consequences. This work aims to analyze changes in the use of lands in Azul, a central district of Buenos Aires province, Argentina, from 1995 to 2011, and to characterize the agricultural expansion process (known as "agriculturization") in that district, by means of landscape definition. Classified satellite images for the1995-2011 period, official statistics of sown areas arranged by crop type and previous studies were used; field surveys were also conducted. The study suggests that the agricultural area of the district increased by 173% in the 1995-2011 period, at the expense of livestock areas. Moreover, wheat was replaced by soybean as the dominant crop in the same period. Agricultural expansion occurred from the peri-mountainous plains landscapes to the hills and depressed plains landscapes. The study of changes in land use and land cover in distinct landscapes will enable researchers to interpret the different scenarios of the agricultural expansion process and will lay bases for environmental management of lands. Desde el comienzo de la difusión de la soja transgénica a mediados de la década del noventa, la agricultura argentina experimentó una notable expansión territorial con cambios de dominancia entre los principales cultivos y diversas consecuencias ambientales. Este trabajo pretende analizar los cambios de uso de suelo en un partido del centro de la provincia de Buenos Aires (Azul), Argentina, entre 1995 y 2011, a fin de caracterizar el proceso de agriculturización mediante la definición de paisajes. Se utilizaron imágenes satelitales clasificadas de 1995 y 2011, estadísticas oficiales de superficies sembradas por cultivo, estudios antecedentes y se realizaron relevamientos de campo. El estudio realizado sugiere que en el partido se incrementó la superficie agrícola 173% entre ambos años, en desmedro de las áreas ganaderas. Asimismo, en el período se produjo un reemplazo de trigo por soja como cultivo dominante. El avance agrícola tuvo lugar desde el paisaje de llanuras periserranas hacia los paisajes de serranías y planicies deprimidas. Se considera que el estudio de los cambios en la cobertura y uso del suelo en los paisajes diferenciados permitirá realizar una lectura de los distintos escenarios del proceso de agriculturización, sentando bases para la gestión ambiental del territorio.
