Aymara Communities in the Lluta River Basin and Precordillera of the Arica and Parinacota Region: Agricultural Activities and Economic Projections

Abstract

The Region of Arica and Parinacota is characterized as an agricultural region located in Atacama Desert at the extreme north of Chile. Its agriculture has allow developing the economy of pre- and post-Hispanic communities, which have been settled since colonial times at different locations in the region. This article is focused on how Aymara communities of Lluta Valley and Precordillera of Arica and Parinacota Region have been included as part of Chilean population, particularly, from social and economic point of view. Furthermore, a characterization of agronomic aspects of the main towns of this zone, and commercialization of agricultural and livestock is included. It must be considered that the evolution of this region would have an important impact in the safeguard on endemic flora and fauna so that it is imperative to protect the genetic heritage of local species and to promote new technologies which allow the production of commercial products from Arica and Parinacota Region.

Did Modern Precipitation Drivers Influence Centennial Trends in the Highlands of the Atacama Desert During the Most Recent Millennium?

“…Precipitation in this region is scarce and largely restricted to austral summer months (DJF), therefore representing a critical environmental resource (García et al., 2007; Garreaud & Aceituno, 2001). Anomalous wet and dry summers and the occurrence of extreme hydrological events have strong impacts over the ecosystems and socioeconomic activities in the Altiplano and the adjacent Andean cordilleras (García et al., 2007; García‐Sanz et al., 2021; Satgé et al., 2019; Sepúlveda‐Chavera et al., 2021). Given these important effects, improving our understanding of the causes and mechanisms leading to precipitation anomalies is crucial for millions of people in Bolivia, Chile, and Argentina.…”
