Introduction
I am interested in understanding the forces of land-use change in agricultural frontiers and how economic, conservation, or zoning policies can influence them now or in the future. I also study the territorial divergences of trans-national eco-regions in South America and the socio-economic factors that may explain differences in their human-natural systems. I coordinate the GLP Working Group LASELS. #socio-ecological land systems, #borders, #frontiers, #governance, #impacts, #trade-offs

Article
Carbon emissions from land-use changes in tropical dry forest systems are poorly understood, although they are likely globally significant. The South American Chaco has recently emerged as a hot spot of agricultural expansion and intensification, as cattle ranching and soybean cultivation expand into forests, and as soybean cultivation replaces gra...
Article
Agricultural expansion and intensification drive the conversion of natural areas worldwide. Scenarios are powerful tools to explore possible future changes in agricultural land use, how these may affect the environment, and how policies may influence land-use patterns. Focusing on Argentina’s prime agricultural areas, the Pampas, Espinal and Chaco,...

Por su continuidad espacial y su relativa homogeneidad ecológica y biofísica, las ecorregiones son un nivel de organización apropiado para discutir y planificar iniciativas de conservación del ambiente a escala regional y nacional. Las interacciones complejas entre las características ecológicas de las ecorregiones, los cambios socioeconómicos loca...
Article
Full-text available
Understanding how biodiversity responds to intensifying agriculture is critical to mitigating the trade‐offs between them. These trade‐offs are particularly strong in tropical and subtropical deforestation frontiers, yet it remains unclear how changing landscape context in such frontiers alters agriculture–biodiversity trade–offs. We focus on the A...
Article
Full-text available
The landscape configuration of socio-ecological land systems results from the interaction between the environmental conditions (relatively homogeneous within ecoregions) and country-level management and land-use decisions. However, social, land-use and sustainability research disciplines often study each independently. We used Euclidean distance an...
Article
Tropical dry forests harbor major carbon stocks but are disappearing rapidly across the globe as agriculture expands into them. Unfortunately, carbon emissions from deforestation in dry forests remain poorly understood as high spatial-temporal and vertical heterogeneity complicate biomass mapping. Here, we use a novel Gradient Boosted Regression fr...
Preprint
As the scientific environment is hierarchical and meritocratic, greater dedication will lead to higher performance. Consequently, scientists with caregiving responsibilities will suffer downfalls in performance. Caregivers are mainly women so their career is more affected than their male counterparts’. Based on a self-perception survey among Argent...
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
Strong trade-offs between agriculture and the environment occur in deforestation frontiers, particularly in the world's rapidly disappearing tropical and subtropical dry forests. Pathways to mitigate these trade-offs are often unclear, as well as how deforestation or different policies alter the option space of available pathways. Using a spatial o...

The use of irrigation ponds has proved to be an efficient alternative for increasing the availability and quality of water resources for irrigation and contributing to the sustainability of agriculture. This article analyses the dynamics of worldwide research on this topic over the last two decades. To do this, a review including a qualitative syst...
Article
Disparity between the knowledge produced and knowledge required to address complex environmental challenges, such as biodiversity conservation and climate adaptation, continues to grow. Systems thinking under the Open Standards for Conservation framework can help close this gap by facilitating interdisciplinary engagement, advancing conversations o...
Article
Currently, 42% of the world's population depends on agriculture for its livelihood, and agriculture drives the economy of most developing countries. Therefore, human life on our planet depends on its sustainability. Research on sustainable land use in agriculture has been gaining increasing relevance since the term 'sustainable development' was coi...
Research
The development of sustainable regions requires an understanding of the land systems that supply the needs of nature and people. At the Open Science Meeting in Bern the Spanish land-use scientist and post-doc María Piquer-Rodríguez explains why the isolated view of disciplines does not correspond to the idea of sustainability – and why a holistic a...
Article
Full-text available
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 land-use changes. Zoning policies were recently enacted in the Argentine Chaco to balance agriculture and conservation, yet th...

Full-text available
Evaluation of conservation policies may generate controversy and lead to diverging interpretations if interest groups do not share a common understanding of concepts, methods, and perspectives. This may have serious consequences if findings are used to orient future policies. To avoid such issues, recent research highlights some necessary steps to...
Article
Full-text available
Rigorous impact assessments test for causal effects of interventions on outcomes of interest. When findings of such assessments become part of political and scholarly controversies, they can be interpreted in unintended ways. The value of the ensuing debate is enhanced by a shared understanding of key concepts, methodological approaches, and evalua...
Article
Agricultural expansion and intensification in South America's dry forests and grasslands increase agricultural production, but also result in major environmental trade-offs. The Pampas and Chaco regions of Argentina have been global hotspots of agricultural land-use change since the 2000s, yet our understanding of what drives the spatial patterns o...
Article
Full-text available
Reducing large-scale deforestation is a key objective of global efforts to mitigate climate change. An important debate concerns the levels of governance at which deforestation can be reduced effectively. Political economic theory and evidence suggests that national governments are more likely than subnational governments in agricultural frontiers...
Article
South America’s tropical dry forests and savannas are under increasing pressure from agricultural expansion. Cattle ranching and soybean production both drive these forest losses, but their relative importance remains unclear. Also unclear is how soybean expansion elsewhere affects deforestation via pushing cattle ranching to deforestation frontier...
Thesis
Agricultural expansion and intensification drive the conversion of natural areas worldwide. This trend will likely continue, particularly in South America, as rising global population, dietary shifts and the increasing importance of biofuels will further accelerate the demand in agricultural products. Yet, it is not clear where and how much product...
Article
Full-text available
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 drivers remains partial though. We used the full Landsat image archive to reconstruct deforestation and post-deforestation dyn...
Article
Full-text available
The subtropical dry forests are experiencing rapid clearing in the southamerican Great Chaco region, mainly for soybean production in Argentina. This is causing biodiversity loss and soil salinization. This forests are unique for the floristic richness and the dense forest cover in a region characterized by semiarid climatic conditions. The authors...

Full-text available
The dry forests of the Chaco in South America are under great land conversion pressure, mostly for establishing pastures and soybean fields. Taking recent estimates into account, the rates at which forests are disappearing are similar to those of the Amazon, but compared to the Amazon, the Chaco remains fairly understudied. The land transformations...
Article
Full-text available
Land-use change is the main driver of habitat loss and fragmentation worldwide. The rate of dry forest loss in the South American Chaco is among the highest in the world, mainly due to the expansion of soybean production and cattle ranching. Argentina recently implemented a national zoning plan (i.e., the Forest Law) to reduce further forest loss....
Article
Full-text available
Anecdotal evidence suggests that socioeconomic shocks strongly affect wildlife populations, but quantitative evidence is sparse. The collapse of socialism in Russia in 1991 caused a major socioeconomic shock, including a sharp increase in poverty. Our goal was to analyze population trends of eight large mammals (5 herbivores and 3 carnivores) in Ru...

Article
Full-text available
Land-use change is a major driver of the global biodiversity crisis, mainly via the fragmentation and loss of natural habitat. Although land-use changes will accelerate to meet humankind's growing demand for agricultural products, conservation planning rarely considers future land uses and how they may affect the connectivity of ecological networks...

Project
This Project aims at describing land-use/cover changes in Latin America (LA) in the most complete and detailed way for the 21st century (2001-2020). It relates these changes to global and regional drivers of change (e.g., commodity markets, population) and explores the consequences of these processes on the efficiency of territorial use (i.e., compatibility and stability of agricultural production, biodiversity conservation and biomass preservation) in the different ecoregions of Latin America).
Project
This project aims at understanding the inter-relations of land-use change and territorial characteristic of nations and eco-regions of South-America. This is part of an institutional project with title "Globalization and land use in Latin America". PI: Prof. Ricardo Grau 2017-2020.
