“…We decided to map the whole area because the mining plants, in fact, have brine pumping and monitoring wells spreading over the entire salt flat far beyond the actual evaporation ponds 41 . Alternative assumptions mapping only the evaporation ponds estimated an area of only 80.53 km 2 in 2017 42 . However, it is important to note that the case of Salar de Atacama was rather isolated; in most cases, no features such as pipelines and wells outside the main mining sites could be identified from the available satellite images.…”

The area used for mineral extraction is a key indicator for understanding and mitigating the environmental impacts caused by the extractive sector. To date, worldwide data products on mineral extraction do not report the area used by mining activities. In this paper, we contribute to filling this gap by presenting a new data set of mining extents derived by visual interpretation of satellite images. We delineated mining areas within a 10 km buffer from the approximate geographical coordinates of more than six thousand active mining sites across the globe. The result is a global-scale data set consisting of 21,060 polygons that add up to 57,277 km2. The polygons cover all mining above-ground features that could be identified from the satellite images, including open cuts, tailings dams, waste rock dumps, water ponds, and processing infrastructure. The data set is available for download from 10.1594/PANGAEA.910894 and visualization at www.fineprint.global/viewer.

“…To illustrate this point, we make a short focus on the example of lithium, a material coming mainly from South America, more precisely from Chile (38% of the world's reserves) [17]. The extraction of lithium in the areas has dramatic consequences on the environment ("the fast expansion of lithium mining operations in the ASF is found to have a strong correlation with the ongoing environmental degradation in the study area" [17]) and on individuals. The social impact of ICT production doesn't appear in Berkhout's paper whereas it is a major effect on humans' organizations.…”

This paper focuses on the evaluation of sustainability in computerbased projects. This type of evaluation has been discussed within the Sustainable Human-Computer Interaction (SHCI) community for a long time and is still considered an unresolved issue. Our paper focuses more particularly on the evaluation framework known as Sustainable Computing Evaluation Framework (SCEF). Here, we describe how such framework can be improved in several ways, and also contribute to the development of the SCEF by a better understanding and integration of sustainability dimension within computer-based projects. This main proposal is composed of three complementary contribution elements. The first contribution element concerns the categorization of socio-environmental impacts as direct, enabling and structural impacts to ensure a global view of impacts over the whole life cycle. The second contribution element concerns the enhancing of the competencies of IT managers through their engagement with the modified SCEF model. The last contribution element includes a feedback loop in the model to compare the estimation of impacts with field data.

“…Curtis et al (2019) show that southern Chile is the region with the most suitable condition for the presence of non-native pine plantations. Liu et al (2019) studied the environmental impact of lithium mining in the Atacama Salt Flat using Landsat imagery and MODIS land products. Martínez Martínez et al, (2019) studies the effect on the effects of the land use changes on the net primary product for south-central Chile from 2000 to 2014.…”

Abstract. The use of satellite images is a modern strategy for the evaluation and prediction of various weather scenarios. In addition, this is a key tool for the development of environmental sciences. Since the end of the last decade, Chile has been suffering from a megadrought associated with climate change. In this context, this study proposes to evaluate the role of land use change in the Middle Maule River sub-basin, located in the Maule Region, Chile. This is an important sector characterized by a significant agricultural and hydroelectric contribution. To do so, this study performs a supervised classification of land cover through the usage of QGIS software and Landsat images for the years 1999 and 2019. The results show the growth of areas without vegetation due to a great drought facing the Central Zone of the country. Additionally, there is a decrease in available bodies of water. This article leaves open future research on the impact of the main economic activities of the region.
