Future scenarios of land use change in the Gran Chaco: how far is zero deforestation?
(Springer, 2022-09-12)The Gran Chaco (Argentina, Paraguay, Bolivia and Brazil) has turned into a global deforestation hotspot as a consequence of the agricultural expansion. These land use changes can lead to large socio-ecological conflicts. ... -
Gestión de bosques nativos con ganadería y manejo del fuego: Desafíos y oportunidades
(Academia Nacional de Agronomía y Veterinaria - Prosa Ediciones, 2023-08)En nuestro país, la gestión del bosque nativo (BN) con ganadería y el manejo del fuego, han sido temas de creciente discusión en los últimos años. Si bien ambos temas no son nuevos, el interés en su abordaje ha aumentado ... -
How does soil organic carbon mediate trade-offs between ecosystem services and agricultural production?
(Elsevier, 2019-08)The basis and essence of life on earth depends on soil health, and its main indicator is the soil organic carbon (SOC) content. Hence, SOC stock is a key component for the supply of many ecosystem services (SOC-mediated ... -
Incidencia de fuegos en la Argentina durante las últimas dos décadas y su asociación con coberturas y usos del suelo en distintos contextos ambientales
(Asociación Argentina de Ecología, 2023-12-01)El uso del fuego ha impulsado grandes cambios en la cobertura de la tierra. Aunque la ocurrencia de fuegos está modulada por condiciones climáticas y por la disponibilidad de biomasa combustible, el ser humano ha modificado ... -
Increasing synergistic effects of habitat destruction and hunting on mammals over three decades in the Gran Chaco
(2020-03-17)Habitat destruction and overexploitation are the main threats to biodiversity and where they co-occur, their combined impact is often larger than their individual one. Yet, detailed knowledge of the spatial footprints of ... -
Interception loss, throughfall and stemflow by Larrea divaricata: The role of rainfall characteristics and plant morphological attributes
(Wiley, 2019-08-28)Rainfall partitioning into interception loss, throughfall and stemflow affects the amount and the spatial heterogeneity of water entering into the soil at the patch scale, strongly controlling net primary productivity of ... -
La investigación en bosques nativos acompañando al desarrollo sustentable
(Colegio de Graduados en Ciencias Forestales de Santiago de Estero, 2020)Los bosques nativos en Argentina, con su gran variedad de ecosistemas que incluyen desde selvas subtropicales hasta bosques subantárticos, brindan a la sociedad diferentes servicios ecosistémicos (alimentos, agua, madera, ... -
Multiscale spatial planning to maintain forest connectivity in the Argentine Chaco in the face of deforestation
(Resilience Alliance, 2018)Agricultural expansion threatens biodiversity due to habitat loss and fragmentation. In the Gran Chaco, a global deforestation hotspot, rampant cropland and pasture expansion raise concerns about the sustainability of these ... -
Native Forests and Agriculture in Salta (Argentina) : conflicting visions of development
(SAGE Publishing, 2011-09)Despite much deforestation in the past, the northwestern Argentinean province of Salta still has more than 6 million hectares of native forests. Land use conversion for agriculture is threatening these forests and the ... -
Partitioning the effects of habitat loss hunting and climate change on the endangered Chacoan peccary
(Wiley, 2023-04-04)Aim: Land-use change and overexploitation are major threats to biodiversity, and cli mate change will exert additional pressure in the 21st century. Although there are strong interactions between these threats, our ... -
Patterns and controls of carbon dioxide and water vapor fluxes in a dry forest of central Argentina
(Elsevier, 2017-12)Covering 16% of global land surface, dry forests play a key role in the global carbon budget. The Southern Hemisphere still preserves a high proportion of its native dry forest cover, but deforestation rates have increased ... -
Positive biodiversity-productivity relationship predominant in global forests
(American Association for the Advancement of Science, 2016-10-14)The biodiversity-productivity relationship (BPR) is foundational to our understanding of the global extinction crisis and its impacts on ecosystem functioning. Understanding BPR is critical for the accurate valuation and ... -
