Los humanos han transformado gran parte de la superficie del planeta en los últimos 300 años.La tala bosques, las prácticas agrícolas subsistencia, intensificación producción agrícola y expansión centros urbanos cambiado drásticamente el paisaje.En centro sur Chile transformaciones estado asociadas, un inicio, a frontera agropecuaria que permitió satisfacer tanto necesidades internas como creciente demanda externa por productos agrícolas.Posteriormente, fuerte incentivo forestación,...
Effects of plantation forestry on biodiversity are controversially discussed in literature. While some authors stress positive effects, others tend to attribute a largely negative influence plantations. One important factor steering the management practices. A second is environmental matrix. Chile offers option analyse both factors jointly. The coastal range central has experienced rapid and widespread replacement native Nothofagus spp. forests favour Pinus radiata Here, remain limited small...
Abstract Western Patagonia (40–56°S) is a clear example of how the systematic lack publicly available data and poor quality control protocols have hindered further hydrometeorological studies. To address these limitations, we present PatagoniaMet (PMET), compilation ground-based (PMET-obs; 1950–2020), daily gridded product precipitation temperature (PMET-sim; 1980–2020). PMET-obs was developed considering 4-step process applied to 523 time series obtained from eight institutions in Chile...
Several impacts over ecosystem services have been produced by land use/cover changes, placing it as one of the main factors driving global environmental change. In present study, SWAT model was used to assess effect changes on hydrology response in Andalien river basin from south-central zone Chile. Three scenarios (LU_1986, LU_2001, and LU_2011) were compared a period 30 years (1984–2013) remove climate variability hydrology. The results show significant decrease total annual flows among...
Groundwater (GW) is the primary source of unfrozen freshwater on planet and in many semi-arid areas, it only water available during low-water periods. In north-central Chile, there has been GW depletion as a result conditions high demand, which unleashed major social conflicts, some due to drought others agribusiness practices against backdrop private management model. The Ligua Petorca watersheds Valparaíso Region were studied order analyze influence climatic anthropogenic factors aquifer...
Abstract. Glaciers are retreating globally and projected to continue lose mass in the coming decades, directly affecting downstream ecosystems through changes glacier runoff. Estimating future evolution of runoff involves several sources data uncertainty, which date have not been comprehensively assessed on a regional scale. In this study, we used Open Global Glacier Model (OGGM) estimate each (with area > 1 km2) Patagonian Andes (40–56° S). As different inventories (n = 2), ice thickness...

Past ice lobe behaviour at Laguna San Rafael is described in documents provided by Spanish and then Chilean explorers from the late seventeenth to early twentieth centuries. These records begin AD 1675, when temperate conditions, probably similar those present, prevailed. At that point, glacier was confined within its valley, not penetrating Laguna. The advanced noticeably during nineteenth century reached a maximum position for `Little Ice Age' around 1875. historical sources suggest slight...
Abstract. A multidisciplinary approach is followed for analysis of the effect changes in land use patterns on hydrologic response Vergara watershed (4340 km2) located central Chile. Probable future scenarios were generated using heuristic rules and logistic regression models, order to identify represent main pressure watershed, namely forestation extensive areas used agriculture with rapid growing exotic species. The was computed a physically based distributed precipitation-runoff model,...
Most water bodies are currently used as receptors for pollutants coming mainly from the industrial and domestic sectors. The Biobío river is subjected to multiple anthropogenic pressures such supply, drinking water, hydroelectric power generation, agriculture, final receptor body of a large amount urban waste, that will intensify due decrease in flow result climate change. In this context, organic contamination has been found sewage discharges oxidizable waste generated by processes. sense,...

In this study, the SWAT (Soil Water Assessment Tool) hydrological model is implemented to determine effect of climate change on various components in two basins located foothills Andes: Quino and Muco river basins. The water cycle analyzed by comparing results climatic data observed past (1982–2016) understand its trend behaviors. Then, variations geographical distribution were using Representative Concentration Pathway (RCP)8.5 scenario periods considering immediate future (2020–2049)...
