Salinization is a process of soil degradation that has been aggravating and expanding along the coast of Peru in the past decades. This process has a negative impact on the inhabitants of the districts of San Antonio and Mala, in the region of Lima, because it does not allow them to perform their traditional agriculture activities throughout the year. It is precisely for this reason that the current thesis aims to understand the process and the current degree of salinization in these districts. With this objective, the rate of expansion of salinization between the years 1976 and 2016 is determined, as well as the causes of its evolution and growth. The methodology followed consisted in three stages. The first one is field stage, where soil samples were collected from the study area. The second one is laboratory stage, where the samples were analyzed in a laboratory to measure parameters of texture, pH, electrical conductivity, color and organic matter. And the third and final one is the cabinet stage, where the entire laboratory data was processed, merged with satellite images from 1976 and 2016 of the cultivated areas in the surface and presented as comparative maps. The results showed that the salinization has expanded from 1976 and 2016, causing the loss of 1 690,47 hectares of arable land. Also, in the majority of the sampling points, the salinity has worsened. This is caused by natural factors, such as proximity to the sea, and anthropic factors, such as low-quality irrigation water that comes from wastewater discharge and polluted irrigation canals. Finally, the study concludes with strategies proposed to control salinization in the research area.
