“…The area's paleoenvironmental data, obtained from the Hindcasting Ecosystems Model (HEMO) application, cover a chronological framework that extends from AD 442 to 1980 CE. During this period, between AD 500 and 900, extreme fluctuations of dry and wet periods were identified, and after AD 1000, stable drier conditions prevailed, coinciding with the abandonment of some sites in the area; these conditions lasted until AD 1500 (Burry et al, 2018).…”

Recent research in the El Alto-Ancasti Highlands (Northwestern Argentina) has identified an extensive agricultural system distributed in between residential sites. This agricultural system seems to have been vulnerable to a gullying system that caused erosion and soil surface loss. The existence of check dams along the inside of these gullies places the beginning of this erosion process at least during its Prehispanic occupation, between 600 and 1000 AD when the agricultural system was active. Here, we characterise the Prehispanic construction of the agricultural landscape, its impact on soil formation and the interaction established by Prehispanic farmers in the area with the local erosive dynamics along the eastern frontier of Northwestern Argentina. Our study indicates the need to pursue further research into runoff agriculture in these environments and its potential contribution for the mitigation of long-term erosive processes and risks, as well as elucidating strategies towards sustainable soil management by modern-day local communities.

Como recientemente han resaltado Danowski y Viveiros de Castro (2014), el Cambio Climático Global es temido en el occidente moderno como la mayor y más certera amenaza hacia el fin del mundo. Para abrir posibilidades de reflexión frente a este contexto actual, se torna necesario atender a los otros fines de otros mundos que la antropología es capaz de traer a discusión. Los "colapsos" y los "cambios climáticos" no son tópicos novedosos en los debates arqueológicos. Buscamos así explorar ciertos cruces entre arqueología y etnografía a partir de nuestro trabajo concreto. La materia prima de nuestra reflexión serán los estudios arqueológicos sobre el fin de la ocupación Aguada en el valle de Ambato (Catamarca, Argentina) basados en datos paleoambientales, y un estudio etnográfico entre pobladores de esa zona en la actualidad. Retomaremos de allí la noción nativa de seca, comprendida como un estado de constante reducción de las intensidades de diversas esferas de la vida local, y el aporte de tal concepto a la arqueología. Palabras claves: sequía, colapsos, arqueología, etnografía, Catamarca. As recently highlighted by Danowski and Viveiros de Castro (2014), global climate change is feared in the modern West as the largest and most certain threat to the world. To open possibilities of reflection in the face of this current context, it is necessary to attend to other "ends of the world" that anthropology is able to bring to the discussion. "Collapse" and "climate change" are not new topics in archaeological debates. We seek to explore possible intersections between archaeology and ethnography from our particular research. Our reflection is based on the archaeological studies, using paleoenvironmental data, of the "end of the Aguada occupation" in the Ambato Valley (Catamarca, Argentina) and on an ethnographic study among current residents of the area. We will take from the ethnographic study the native notion of "seca", understood as a state of constant reduction of the intensities of diverse spheres of local life, and its implications for archaeology.

Projections of future scenarios are scarce in developing countries where human activities are increasing and impacting land uses. We present a research based on the assessment of the baseline trends of normalized difference vegetation index (NDVI), precipitation, and temperature data for the Khuzestan Province, Iran, from 1984 to 2015 compiled from ground-based and remotely sensed sources. To achieve this goal, the Sen’s slope estimator, the Mann-Kendall test, and Pearson’s correlation test were used. After that, future trends in precipitation and temperature were estimated using the Canadian Earth System Model (CanESM2) model and were then used to estimate the NDVI trend for two future periods: from 2016 to 2046 and from 2046 to 2075. Our results showed that during the baseline period, precipitation decreased at all stations: 33.3% displayed a significant trend and the others were insignificant ones. Over the same period, the temperature increased at 66.7% of stations while NDVI decreased at all stations. The NDVI–precipitation relationship was positive while NDVI–temperature showed an inverse trend. During the first of the possible future periods and under the RCP2.6, RCP4.5, and RCP8.5 scenarios, NDVI and precipitation decreased, and temperatures significantly increased. In addition, the same trends were observed during the second future period; most of these were statistically significant. We conclude that much assessments are valuable and integral components of effective ecosystem planning and decisions.
