ZULAICA, Laura; VAZQUEZ, Patricia  y  DAGA, Daiana. Territorial transformations in the peri-urban horticultural area of Mar del Plata (Argentina) and its incidence on water erosion processes. Rev. geogr. Norte Gd. [online]. 2020, n.75, pp.179-200. ISSN 0718-3402.  http://dx.doi.org/10.4067/S0718-34022020000100179.

The periurban spaces of Latin American cities exhibit deep territorial transformations and emerging problems from occupation without planning. The horticultural production, that characterizes numerous peri-urban areas, tends to expand and intensify without considering the potential and limitations of the resources that support it. The present paper characterizes the horticultural transformations of the peri-urban of Mar del Plata (Argentina) city, and analyze its incidence on erosion processes. Based on previous studies, a Landsat image (2017) was classified and the Universal Soil Loss Equation was applied in three landscape units previously defined. The open field horticultural surface increased 80% between 1989 and 2017, as well as current and potential erosion that reach 68,612 tn/year and 221,219 tn/year in 2017, respectively. It is proposed to advance in the diagnosis of the problem to define territorial management strategies in accordance with the principles of sustainability.

Palabras clave : peri-urban horticulture; landscape units; current and potential erosion; territorial sustainability.
