Agricultural expansion and the ecological marginalization of forest-dependent people
(National Academy of Sciences, 2021-11-02)Agricultural expansion into subtropical and tropical forests causes major environmental damage, but its wider social impacts often remain hidden. Forest-dependent smallholders are particularly strongly impacted, as they ... -
Agricultural expansion in the Semiarid Chaco: poorly selectivecontagious advance
(Elsevier, 2016-09)Clearance for agriculture or cattle ranching was the dominant land-cover change during the last two decades in the South American Dry Chaco. The Argentinean portion has been particularly affected, presenting greater ... -
Artificial perches for birds in deforested areas favour a seed rain similar to woodland remnants
(Springer, 2022-11)The lack of seeds represents one of the highest difficulties to overcome for the ecological restoration of areas that have been deforested. This study evaluates the effectiveness of artificial perches in increasing the ... -
Aspectos ecológicos y ambientales de los bosques nativos y plantaciones forestales en la Argentina: Una visión panorámica y conceptual.
(Fundación Ciencia, Educación y Cultura. (FECIC), 2015)El objetivo de éste trabajo es plantear de manera sintética cuales son los factores principales asociados a la presencia y distribución de los ecosistemas forestales del país, que rasgos caracterizan a los distintos tipos ... -
Back to the people: The role of community-based responses in shaping landscape trajectories in Oaxaca, Mexico.
(Elsevier, 2021-01)Land use change results from top-down drivers, such as policies, trade, and migration. Land use change may also result from community-based responses. In Mexico, rural communities govern most of the country's forests. This ... -
Biodiversity loss in deforestation frontiers: Linking occupancy modelling and physiological stress indicators to understand local extinctions
(Elsevier, 2019-05-27)Tropical deforestation is a main driver of the global biodiversity crisis. Impact assessments typically focus on species' presence, which means impacts are detected when local extinctions have occurred – and thus when it ... -
Can't see the forest for the trees: can declining deforestation trends in the Argentinian Chaco Region be ascribed to efficient law enforcement?
(Elsevier, 2018)A national “Forest Law” passed in Argentina in 2007 mandated provincial governments to set up and implement land use planning processes in order to protect their native forests and regulate the expansion of large-scale ... -
Causas e impactos de la deforestación de los bosques nativos de Argentina y propuestas de desarrollo alternativas
(Ministerio de Ambiente y Desarrollo Sostenible, Argentina, 2020)En el marco de la Ley Nacional Nº 26.331 de Presupuestos Mínimos de Protección Ambiental de los Bosques Nativos, se entiende como bosque nativo a todos los ecosistemas forestales naturales en distinto estado de desarrollo, ... -
Central and South America
(Cambridge University Press, 2022-08)The chapter is divided into two main sections. The first section follows an integrative approach in which hazards, exposure, vulnerability, impacts and risks are discussed following the eight climatically homogeneous ... -
Changes in evapotranspiration and phenology as consequences of shrub removal in dry forests of central Argentina
(Wiley, 2015-10)More than half of the dry woodlands (forests and shrublands) of the world are in South America, mainly in Brazil and Argentina, where in the last years intense land use changes have occurred. This study evaluated how the ... -
Combined effects of agrochemical contamination and forest loss on anuran diversity in agroecosystems of east-central Argentina
(Elsevier, 2020-11)Agricultural expansion and intensification has led globally to a rapid landscape structure change and high agrochemical use resulting in habitat loss and degraded environmental quality. Co-occurrence of landscape change ... -
Deforestación de los bosques nativos de Argentina: causas, impactos y propuestas de desarrollo alternativas
(Colegio de Graduados en Ciencias Forestales de Santiago de Estero, 2020)En el marco de la Ley Nacional Nº 26.331 Presupuestos Mínimos de Protección Ambiental de los Bosques Nativos, se entiende a bosque nativo a todos los ecosistemas forestales naturales en distinto estado de desarrollo, de ... -
Deforestation and cattle expansion in the Paraguayan Chaco 1987–2012
(2017-04)The dry forests of Latin America are among the most dynamic deforestation frontiers in the world and are important carbon and biodiversity reservoirs. Our knowledge on the spatial patterns of deforestation and its proximate ... -
Determinación del carbono orgánico del suelo en los bosques de Argentina
(Red Argentina de Ciencia y Tecnología Forestal, 2023-03-27)El carbono orgánico del suelo (COS) es un componente muy dinámico y clave para el funcionamiento de los ecosistemas (productivos y naturales) y los servicios que pueden brindar. La capacidad de almacenamiento del COS depende ... -
Dinámica y consecuencias del cambio en la cobertura y el uso del suelo en el Chaco Semi-Árido
(Facultad de Agronomía, Universidad de Buenos Aires, 2014-08-12)La deforestación en Sudamérica afecta principalmente a tres ecosistemas: El Cerrado en Brasil, la selva de Chiquitanos en Bolivia y el Gran Chaco en Bolivia, Paraguay y Argentina, siendo en estos dos últimos países en ... -
Ecosystem Services in Patagonia: A Multi-Criteria Approach for an Integrated Assessment
(Springer Nature, 2021-04-27)This book aims to quantify and discuss how societies have directly and indirectly benefited from ecosystem services in Patagonia; not only in terms of provisioning and cultural services, but also regulating and supporting ... -
Effect of deforestation and introduction of exotic grasses as livestock forage on the population dynamics of the cattle tick Rhipicephalus (Boophilus) microplus (Acari: Ixodidae) in northern Argentina
(2013-12)The effect of deforestation and the introduction of exotic grasses on the population dynamics of Rhipicephalus (Boophilus) microplus in northern Argentina was analysed. Biological parameters that were measured included ... -
Effect of deforestation and subsequent land-use management on soil carbon stocks in the South American Chaco
(European Geosciences Union, 2018)The sub-humid Chaco region of Argentina, originally covered by dry sclerophyll forest, has been subjected to clearing since the end of the '70 and replacement of the forest by no till farming. Land use changes produced a ... -
