1. Agricultural landscapes as coupled human-natural systems: Are there commonalities in coupling mechanisms?

A defining feature of Coupled Human and Natural Systems (CHANS) is that interactions occur between social and biophysical components at multiple spatial and temporal scales. In this symposium we will apply and critique co-evolutionary theory which posits that environmental and social subsystems interact through feedbacks and co-evolve. We define adaptive coupling as linkages between biophysical-social subsystems that prevent environmental degradation and maintain the integrity of the biosphere and social systems. If linkages and interactions between subsystems lead to environmental or social degradation, we consider this to be a case of maladaptive coupling. This symposium will analyze and compare interactions and feedbacks between and within social and biophysical subsystems that serve to couple the human-natural subsystems in agricultural landscapes. The goal is to identify commonalities in coupling mechanisms that govern the trajectory of human-nature linkages agricultural systems. A diverse array of agricultural systems, ranging from smallholder, subsistence farming systems in the Bolivian Andes to the intensive, industrial grain production systems of the US Corn Belt will be examined. These agri-food production systems vary in terms of the scale and importance of market outlets as well as the environmental and social context in which they are situated. To compare these diverse agricultural systems, speakers will address three synthetic questions:
1) What are the social and biophysical drivers and consequences of the agricultural system and at what scales do they operate?
2) Is there evidence for adaptive/maladaptive coupling?
3) What are the metrics for assessing adaptive coupling? Is adaptive coupling scale dependent? For example, is there evidence for adaptive coupling at local or other scales?

2. Land change analysis integrating maps and local knowledge

This paper session presents a funded on-going research project called “Maps and Locals (MALS)” to examine land change in a cross-site context. The project compares maps of land categories from more than two points in time at several sites of the Long Term Ecological Research (LTER) network. Statistical analysis of the maps informs the process to solicit knowledge from the local population. Local knowledge of residents informs mapping to produce an integrative land change analysis. This session has four 20-minute presentations plus a 20-minute discussion.
