Dams and population displacement on China’s Upper Mekong River: Implications for social capital and social–Ecological Resilience
Global Environmental Change-human and Policy Dimensions, 2020Co-Authors: Bryan Tilt, Drew GerkeyAbstract:Abstract China is home to nearly half of the world’s 50,000 large dams, which provide irrigation, flood protection, and hydroelectricity. Most of these projects involve substantial population displacement, which can disrupt social capital, the webs of interdependence and support that community members maintain with one another through relationships of trust and reciprocity. We use new empirical evidence to examine the association between dam-induced displacement and social capital in China and interpret our findings in the context of social–Ecological Resilience theory. Our focus is on agricultural households on the Upper Mekong River, where four large hydropower dams have been constructed over the past twenty years. Our broad finding is that resettlement is associated with diminished social capital, as measured by two key indicators: inter-household exchange of financial resources, and inter-household exchange of agricultural labor. These effects differ across the four dam sites in the study based on local economic conditions and changes in resettlement policy. We find that population resettlement is associated with markedly lower levels of agricultural labor exchange. In an economically under-developed setting, this reduces the depth and breadth of social support that agricultural households rely on to produce crops for subsistence and income. This in turn diminishes social–Ecological Resilience because social capital is a key factor that helps agricultural or resource-dependent communities manage risk and adapt to changes and stressors. We consider the policy implications of our findings in the context of scientific and industry efforts to minimize social harm, promote economic vitality, and improve the sustainability of hydropower as a form of renewable energy.

Evaluating Ecological Resilience with global sensitivity and uncertainty analysis
Ecological Modelling, 2013Co-Authors: Stephen G. Perz, Gregory Kiker, Rafael Muñoz-carpena, Robert D. HoltAbstract:Concern about catastrophic tipping points has motivated inquiry to better understand ecosystem dynamics in the presence of human action. This requires that we confront multiple challenges in the evaluation of complex systems. One challenge is that Resilience has proven difficult to quantify; another issue is that the value of model complexity relative to system complexity is disputed; and finally, local methods for assessing uncertainty are inadequate for more complex models. We address these three challenges simultaneously by proposing a means of evaluating Ecological Resilience via employment of global sensitivity and uncertainty analysis and comparing models of varying complexity. We suggest that probability distribution functions in output from global sensitivity and uncertainty analysis can be interpreted in terms of ball-and-cup diagrams used in systems theory to visualize Ecological Resilience. This permits quantification of Ecological Resilience in terms of the probability of whether a system will remain in a pre-existing state or shift to a different state. We outline the methods for using global sensitivity and uncertainty analysis to evaluate Ecological Resilience and provide examples from recent research. We highlight applications of these methods to assessment of ecosystem management options in terms of their ramifications for Ecological Resilience. © 2013.

regional integration and local change road paving community connectivity and social Ecological Resilience in a tri national frontier southwestern amazonia
Regional Environmental Change, 2012Co-Authors: Stephen G. Perz, Liliana Cabrera, Lucas Araujo Carvalho, Jorge Castillo, Rosmery Chacacanta, Rosa E Cossio, Yeni Franco Solano, Jeffrey Hoelle, Leonor Mercedes Perales, Israel PuertaAbstract:Initiatives for global economic integration increasingly prioritize new infrastructure in relatively remote regions. Such regions have relatively intact ecosystems and provide valuable ecosystem services, which has stimulated debates over the wisdom of new infrastructure. Most prior research on infrastructure impacts highlights economic benefits, Ecological damage, or social conflicts. We suggest a more integrative approach to regional integration by appropriating the concepts of connectivity from transport geography and social–Ecological Resilience from systems ecology. Connectivity offers a means of observing the degree of integration between locations, and social–Ecological Resilience provides a framework to simultaneously consider multiple consequences of regional integration. Together, they offer a spatial analysis of Resilience that considers multiple dimensions of infrastructure impacts. Our study case is the southwestern Amazon, a highly biodiverse region which is experiencing integration via paving of the Inter-Oceanic Highway. Specifically, we focus on the “MAP” region, a tri-national frontier where Bolivia, Brazil, and Peru meet and which differs in the extent of highway paving. We draw on a tri-national survey of more than 100 resource-dependent rural communities across the MAP frontier and employ indicators for multiple dimensions of connectivity and social–Ecological Resilience. We pursue a comparative analysis among regions and subregions with differing degrees of community connectivity to markets in order to evaluate their social–Ecological Resilience. The findings indicate that connectivity and Resilience have a multifaceted relationship, such that greater community connectivity corresponds to greater Resilience in some respects but not others. We conclude by noting how our findings integrate those from heretofore largely disparate literatures on infrastructure. The integration of transport geography with Resilience thought thus stands to advance the study of infrastructure impacts.
