Understanding differences in land systems and their social-ecological impacts within and across ecoregions in South America
Land use is crucial for human societies, providing essential food, feed and materials. At the same time, land-use has major impacts on the environment and is a driver of many of the major sustainability challenges we face in the 21st century – from climate change to soil erosion to the ongoing biodiversity crisis. Understanding these trade-offs, and finding ways to manage them, is therefore a central challenge for science and for society at large. Trade-offs between land use, and agriculture in particular, and the socio-environment do not play out randomly in space. Often, those regions that are best for agriculture also harbor high levels of carbon and biodiversity. Likewise, many of these regions are culturally rich, for example harboring many ethnic groups. Trade-offs are mediated both via environmental conditions (e.g., agro-ecological conditions) and the institutional setup (e.g., governance systems, policy frameworks), yet which of these sets of factors dominate is often unclear. Understanding how these factors shape geographies of trade-offs is therefore important to identify ways how they can be managed– and thus how regions could develop sustainably. The overarching goal of my proposal is to explore whether environmental or institutional conditions are more important in shaping the trade-offs between agricultural development and socio-ecological systems. I will approach this question using a land-system framework, where land systems are defined as social-ecological systems where interactions between nature and society happen dominantly via land use (agriculture in my case). I will focus on South America, and here on the agricultural regions from Amazonia (Brazil) to the Pampas (Argentina), a region of about 5 million square kilometers. This region is a perfect case study, as it is among the most important agricultural regions of the world, provides a large variety of environmental and governmental setups, and has several ecoregions that extend across multiple countries. This provides a unique natural experiment situation to understand the importance of environmental vs. institutional factors.
My project will characterize agricultural land systems and will assess transboundary differences within transnational ecoregions and across national ecoregions in South America (obj. 1). It will also evaluate environmental and social indices for this region (obj. 2). Together, this will allow assessing potential socio-economic and environmental trade-offs (obj 3). As a result, I will be able to discuss if ecological or institutional conditions shape socio-environmental impacts in agricultural regions. The results of my project will deepen our understanding on the power of institutions in achieving sustainable development and thus have direct relevance for sustainability science as well as for policy making and governance in the region.
