This paper explores the value proposition of using systems tools to model the interlinkages that exist between the security of water, energy, land, and food (WELF) resources and peace. The intersection between these five sectors, referred to as the WELF-Peace nexus, is complex, unfolds in a constrained landscape of specific context and scale, and involves the interaction of multiple systems and their subsystems. Multiple states of combined community peace and resource security are possible. This paper demonstrates the value proposition of using system dynamics to account for the interdependencies that exist between the four sectors of the WELF nexus and the domains of positive peace. Two existing indices, the Positive Peace Index and the Pardee RAND Food-Energy-Water (FEW) Security Index proposed by the Institute for Economy and Peace (IEP) are considered, and their interaction analyzed using system dynamics. The approach can be used to explore different scenarios involving linkages between positive peace and different forms of FEW resource synergy and tradeoff.

Experience over the last decade has demonstrated a gradual rise in global temperatures, which coupled with the unpredictable precipitation patterns (rainfall & Snow/ glacier melt are considered as important hydrologic process in the Himalayan basins), are expected to seriously affect the melt characteristics and further increase pressure on available water resources (both quantity and quality). The situation is being exacerbated intensified by the increasing water demands from agriculture, industry and rising population. However, current investigations reveal that there is a lack of a general framework for assessment. The major responsibility of the planning community is to adopt rational planning approach addressing the complexity of the system, yet it is appearing that the models used at various stages are not well developed to keep the same pace. This demands the acknowledgment and a better understanding of the dynamic inter-linkage and interdependence of the complex systems and sub-systems (namely physical, social, economic, ecology, environment, infrastructure, and institutional subsystems) using system dynamics technique. The aim of this paper is to develop a methodology for assessing the climate change and its impact on a region by demonstrating the inadequacy of sectoral and silobased planning approaches to address the complex sustainable development challenges whose interdependencies and inter-linkages transcend individual sectors and administrative borders. Further, this paper attempts to present the review of research done on the use of an integrated approach by using system dynamics technique in the context of evolving development plans. It concludes with extending the knowledge to support climate change adaptation and mitigation decisions to achieve sustainable development at the regional scale.

As we enter the third decade of the 21st century, the value proposition of promoting sustainability and peace in the world has become more imperative than ever. It is an appropriate time to pause and reflect on what a post-pandemic COVID-19 world will look like and what constitutes a new mindset toward a more sustainable, stable, peaceful, and equitable world where all humans live with dignity and at peace. As emphasized in this paper, the new mindset must acknowledge that sustainability and peace are two entangled states of dynamic equilibrium. It is hard to envision a sustainable world that is not peaceful and a peaceful world that has not endorsed sustainable practices. This paper looks more specifically at the value proposition of adopting a systems approach to capture the linkages between selected development sectors (e.g., SDGs) and peace sectors (e.g., positive, negative, and cultural). Basic system dynamics (SD) models are presented to illustrate the peace–development nexus dynamics. The models are general enough to be used for different contexts and scales.

PurposeThis paper aims to develop a system dynamics (SD) model to identify causal relationships among the elements of failure modes and effects analysis (FMEA), i.e. failure modes, effects and causes.Design/methodology/approachA causal loop diagram (CLD) has been developed based on the results obtained from interdependencies and correlations analysis among the FMEA elements through applying the integrated approach of FMEA-quality function deployment (QFD) developed by Shaker et al. (2019). The proposed model was examined in a steel manufacturing company to identify and model the causes and effects relationships among failure modes, effects and causes of a roller-transmission system.FindingsFindings indicated interactions among the most significant failure modes, effects and causes. Moreover, corrective actions defined to eliminate or relieve critical failure causes. Consequently, production costs decreased, and the production rate increased due to eliminated/decreased failure modes.Practical implicationsThe application of CLD illustrates causal relationships among FMEA elements in a more effective way and results in a more precise recognition of the root causes of the potential failure modes and their easy elimination/decrease. Therefore, applying the proposed approach leads to a better analysis of the interactions among FMEA elements, decreased system's failure rate and increased system availability.Originality/valueThe literature review indicated a few studies on the application of SD methodology in the maintenance area, and no study was performed on the causal interactions among FMEA elements through an FMEA-QFD based SD approach. Although the interactions of these elements are significant and helpful in risks ranking, researchers fail to investigate them sufficiently.
