          Abstract

          En la segunda mitad del siglo XX algunos salares del área circumpuneña fueron objeto de estudio científico-técnico con fines productivos para generar pronósticos de rendimiento en la cosecha de elementos fisicoquímicos y sales de interés para la minería no metálica. La revisión de los Archivos de la Administración de Chile ha permitido acceder a la memoria institucional de la Corporación de Fomento de la Producción y conocer algunos de los procedimientos del proceso de institucionalización de las lógicas de explotación. Esta historia de las tecnologías de la energía solar para la cosecha de sales demuestra que, en la era del Antropoceno, la producción de hiperobjetos como el elemento litio tiene efectos transformadores para la historia ecoeconómica.

          Translated abstract

          In the second half of the 20th century, some salt flats in the circumpeña area were the object of scientific-technical studies for productive purposes to generate yield forecasts for harvesting physical-chemical elements and salts interest for non-metallic mining. The review of the Chilean Administration Archives has allowed access to the institutional memory of the Corporación de Fomento de la Producción and to know some of the procedures of institutionalization of the mining logics. This history of solar energy technologies for salt harvesting demonstrates that, in the Anthropocene era, the production of hyper-objects such as lithium has transformative effects on eco-economic history.

            Defining the anthropocene.

            Time is divided by geologists according to marked shifts in Earth's state. Recent global environmental changes suggest that Earth may have entered a new human-dominated geological epoch, the Anthropocene. Here we review the historical genesis of the idea and assess anthropogenic signatures in the geological record against the formal requirements for the recognition of a new epoch. The evidence suggests that of the various proposed dates two do appear to conform to the criteria to mark the beginning of the Anthropocene: 1610 and 1964. The formal establishment of an Anthropocene Epoch would mark a fundamental change in the relationship between humans and the Earth system.

              The Anthropocene: conceptual and historical perspectives.

              The human imprint on the global environment has now become so large and active that it rivals some of the great forces of Nature in its impact on the functioning of the Earth system. Although global-scale human influence on the environment has been recognized since the 1800s, the term Anthropocene, introduced about a decade ago, has only recently become widely, but informally, used in the global change research community. However, the term has yet to be accepted formally as a new geological epoch or era in Earth history. In this paper, we put forward the case for formally recognizing the Anthropocene as a new epoch in Earth history, arguing that the advent of the Industrial Revolution around 1800 provides a logical start date for the new epoch. We then explore recent trends in the evolution of the Anthropocene as humanity proceeds into the twenty-first century, focusing on the profound changes to our relationship with the rest of the living world and on early attempts and proposals for managing our relationship with the large geophysical cycles that drive the Earth's climate system.
