The agricultural expansion in South America's Dry Chaco: regional hydroclimate effects [PDF]

Hydrology and Earth System Sciences, 2023
The Gran Chaco ecoregion is South America's largest remaining continuous stretch of dry forest. It has experienced intensive deforestation, mainly in the western part known as the Dry Chaco, resulting in the highest rate of dry-forest loss globally ...

Agents of Forest Disturbance in the Argentine Dry Chaco

Remote Sensing, 2022
Forest degradation in the tropics is a widespread, yet poorly understood phenomenon. This is particularly true for tropical and subtropical dry forests, where a variety of disturbances, both natural and anthropogenic, affect forest canopies.

Deforestation and fragmentation of Chaco dry forest in NW Argentina (1972–2007)

Forest Ecology and Management, 2009
Abstract The sustained increase in the global food demand has favoured the recent expansion of industrial agriculture into neotropical dry forest ecosystems, with resulting changes in their extent and spatial configuration. Based on Landsat satellite images, we analyzed changes in forest cover and landscape configuration over an area of 600 by 100 km

Characterizing forest disturbances across the Argentine Dry Chaco based on Landsat time series

International Journal of Applied Earth Observations and Geoinformation, 2021
Forest loss in the tropics affects large areas, but whereas full forest conversions are routinely assessed, forest degradation patters remain often unclear.

Indigenous starter cultures to improve quality of artisanal dry fermented sausages from Chaco (Argentina) [PDF]

International Journal of Food Science, 2015
Lactic acid bacteria (LAB) and coagulase negative cocci (CNC) were isolated from artisanal dry sausages sampled from the northeastern region of Chaco, Argentina. In order to evaluate their performance in situ and considering technological features of the

Improved chemical control of Chagas disease vectors in the dry Chaco region. [PDF]

J Med Entomol, 2013
The effectiveness of two doses of suspension concentrate (SC) pyrethroid insecticides in suppressing peridomestic populations of Triatoma infestans (Klug) was evaluated in 28 rural communities located in Santiago del Estero province, northwestern Argentina, including 388 houses and 1,516 identified sites.

Simulating the Dry Chaco Hydrology under Deforestation Pressure [PDF]

, 2020
Abstract. Various regions in the world experience land cover and land use changes. One such a region is the Dry Chaco ecoregion in South America, characterized by deforestation and forest degradation since the 1980s. In this study, we simulated the water balance over the Dry Chaco and assessed the impact of land cover changes thereon, using three ...

Rainwater harvesting in Dry Chaco: Regional distribution and local water balance [PDF]

Journal of Arid Environments, 2015
Rainwater harvesting (RWH) has been essential for the establishment of human settlements in many dry regions of the world that lacked suitable surface or groundwater resources. A vast fraction of the South American Dry Chaco ecoregion still relies on RWH to support, not only livestock production, but domestic and industrial uses as well.

Spatial patterns of soil salinity in the central Argentinean Dry Chaco

Anthropocene, 2022
The Dry Chaco is a semi-arid ecoregion in South America that hosts one of the largest dry forests in the world, but expansion of dryland agriculture and cattle ranching led to gradual conversion of native vegetation to anthro- pogenic land cover. The potential impact of these newly established agricultural lands on the surrounding environment is of ...
