Science and Engineering have no borders !

Prof. Bernard Amadei, Founding President of Engineer-without-Borders (EWB)-USA and co-founder of EWB-International, will be "Navigating the Complexity across the Peace-Sustainability-Climate security NEXUS"

Title: "Navigating the Complexity across the Peace-Sustainability-Climate security NEXUS" 

When: Thursday June 29 at 4 pm CET, 10 am ET



Dr. Amadei is a Distinguished Professor and Professor of Civil Engineering at the University of Colorado at Boulder. He received his Ph.D. in 1982 from the University of California at Berkeley. Dr. Amadei is the Founding Director of the Mortenson Center in Engineering for Developing Communities. He is also the Founding President of Engineers Without Borders - USA and the Engineers Without Borders-International network co-founder. Dr. Amadei is an elected member of the US National Academy of Engineering and the National Academy of Construction, among other distinctions. He is also an elected Senior Ashoka Fellow. Dr. Amadei holds seven honorary doctoral degrees (UMass Lowell; Carroll College; Clarkson; Drexel; Worcester Polytechnic Institute; the Technion in Israel; and SUNY-ESF). In 2013 and 2014, Dr. Amadei served as a Science Envoy to Pakistan and Nepal for the US Department of State. In addition, Dr. Amadei holds a commercial pilot license (multi-engine land, instrument)



The literature contains many case studies demonstrating the direct or indirect constraining and threatening impact of conflict and climate change on community livelihood and security. As a result, promoting peace and sustainability in human development and security while accounting for the risks associated with climate change and other adverse events has become more imperative at different scales, from the local to the global. The intersection of peace, sustainability, and climate security or their opposites (i.e., conflict, unsustainability, and climate vulnerability) is rarely articulated with a systemic mindset.  

This paper makes a case for using an integrated, coherent, and multi-solving approach to addressing human development and security issues. It explores, more specifically, the underlying dynamic across the peace-sustainability-climate security triple-nexus. System dynamics is used to model the interaction between peace, sustainability, and climate security and their counterparts (conflict, unsustainability, and climate insecurity)

Peace, sustainability, and climate security are entangled states (or cultures) that emerge from the interactions of shared systems subject to various constraints, barriers, and adverse events. The three states and the systems influence each other. Their coherence is better captured using a systems approach rather than considering them in isolation. To do so, decision-makers involved in development need to be able and willing to make decisions in complex, ambiguous, and uncertain environments with a system lens that embraces complexity rather than organized simplicity. 

​There are many ways of approaching the coherence between peace, sustainability, and climate security. The approach used here recognizes that there are no one-size-fits-all unified, static, and optimized static states of peace, sustainability, and climate security as they are context, scale-specific, and time-dependent.
