Article
Cattle ranching has increased globally in the last decades, and although pasture expansion is well documented across different regions, there is little understanding of the intensity at which cattle operate in these areas. With freely available Sentinel-2 satellite imagery, we mapped for the first time polyethylene silage bags used for forage conse...
Article
Significance Millions of people globally rely on forest-based resources for their livelihoods, particularly in the tropics and subtropics. Deforestation is often hypothesized to diminish forest-dependent communities’ resource base and to push them toward more-marginal environments, but such ecological marginalization has rarely been quantified. We...
Article
The current challenge of the Chaco Seco beef cattle system is focused on increasing production through intensification, without expanding the agricultural frontier towards natural ecosystems and reducing externalities. The aim of this study was to quantify the difference in live weight (LW) productivity and in greenhouse gases emission intensity of...
Article
In dry woodland regions, silvopastures have emerged as a promising option to balance cattle production, carbon storage and biodiversity. However, one of the major challenges in these systems, particularly when implemented in a matrix of natural vegetation, is the preservation of tree populations in the face of management actions implemented by ranc...
Article
Impacts of cattle production vary among different production systems, but data on their distribution is scarce for most world regions. In this work, we combine datasets on cattle vaccination locations and land cover in a regression framework to define and map major cattle production systems in the Argentinean Dry Chaco. We also explore how cattle o...
Chapter
The Dry Chaco is mostly known as a forested ecosystem. However it includes natural grasslands, savannas, scrublands, and wetlands. With one of the highest global deforestation rates in the last two decades and only 12% of the area protected, the concern about land-use change in this ecoregion has raised exponentially; but conservation initiatives d...

Los sistemas silvopastoriles se han propuesto como alternativas productivas que pueden mitigar las emisiones de gases de efecto invernadero mediante el secuestro de carbono. En el Chaco Seco Argentino, se realizan en bosques nativos y actualmente existen 14 millones de hectáreas que podrían tener este uso debido al reciente ordenamiento de bosques....

Silvopastoril systems in Argentinean Dry Chaco are implemented in native woodland disturbing shrub layer to plant. These have been proposed as systems that maintain forest ecosystem services such as carbon sequestration. In recent years, they have increased in area and there are still 14 million of hectares in the region that allow silvopastoral pr...

En Argentina los sistemas silvopastoriles en bosque nativo son el método productivo más establecido en zonas amarillas desde la implementación de la ley de ordenamiento territorial. Aunque estos sistemas podrían ocupar 14 millones de hectáreas en el futuro del Chaco Seco, aún no se han documentado los efectos a escala regional del manejo silvopasto...
Chapter
Full-text available
Silvopastoral systems (SPS) provide a wide range of non-provisioning ecosystem services including carbon (C) sequestration. Well-managed SPS outperform both grasslands/pastures and forests in terms of C by increasing soil and biomass C storage. In this Chapter, C sequestration information from native forests and tree plantations under silvopastoral...

Conference Paper
Full-text available
INTRODUCCIÓN: En Tucumán, la caña de azúcar tradicionalmente cultivada en secano se ha expandido hacia zonas de menor aptitud productiva, como las sub regiones sub húmeda-seca y semiárida de la llanura chaco-pampeana-ubicadas al este de la provincia-, donde algunos productores incorporaron sistemas de riego por goteo con agua sub-superficial. Este...

Project
The main goal of this project is to evaluate medium-large mammal persistence in agroecosystems of the Argentine Dry Chaco, by addressing both their presence and habitat use; and the local population attitudes towards them. This will be achieved through 3 specific objectives: 1. Medium-large mammal (MLM) ecology in Argentine Dry Chaco agroecosystems. We will assess MLM presence, activity patterns, and habitat use in agroecosystems of the Argentine Dry Chaco; and will investigate the effects of the anthropic land-uses that characterize these agroecosystems on these species. We will especially address the potential of silvopastoral systems to harbor MLM, since this recent land-use is widely spread in the region, yet its sustainability has not been evaluated. 2. Interactions, perceptions and conflicts between MLM and humans in Argentine Dry Chaco agroecosystems. We will characterize the interactions between the different stakeholders of the region (e.g., local peasants, small landowners, large landowners) and MLM, including the quantification of livestock and poultry predation by carnivores. 3. Educational and participatory workshops and local dissemination of the results, to generate awareness on MLM; share the results of our project; and as a first step to identify possible, socially suitable actions for the mitigation of conflicts between people and MLM in the region. _____________________________________________________________________ El principal objetivo de este proyecto es evaluar la persistencia de mamíferos medianos-grandes (MMG) en agroecosistemas del Chaco Seco Argentino, analizando su presencia y uso del hábitat; y las actitudes de los actores sociales hacia estos. Este objetivo general será alcanzado mediante 3 objetivos específicos: 1. Ecología de MMG en agroecosistemas del Chaco Seco argentino: Evaluaremos la presencia, patrones de actividad y uso del hábitat de MMG en agroecosistemas del Chaco Seco argentino; y analizaremos el efecto de los distintos usos antrópicos del suelo sobre estas especies. Analizaremos específicamente el potencial de los sistemas silvopastoriles para conservar MMG, dado que este manejo del suelo se está expandiendo en la región. 2. Interacciones, percepciones y conflictos entre MMG y humanos en agroecosistemas del Chaco Seco argentino: caracterizaremos las interacciones entre distintos actores sociales de la región (productores grandes, pequeños, puesteros) y MMG, incluyendo la cuantificación de los eventos de depredación de ganado por parte de carnívoros. 3. Desarrollo de talleres participativos y educativos, y difusión local de los resultados, como primer paso para identificar posibles acciones socialmente aceptadas para la mitigación de los conflictos entre humanos y MMG en la región.
