The antecedents of green value chain implementations were considered from four dimensions namely regulations, public concerns, expected competitive advantage and top management commitment; green value chain initiatives were considered from three dimensions namely green primary activities, green internal support activities and green external support activities; the results of green value chain implementations were considered from two dimensions namely economic performance and socio-ecologic performance. A model was created according to the objectives of the study and hypotheses were formed. Multiple regression analyses were performed to investigate the relationships between the antecedents and initiatives of green value chain implementations. A relationship was not observed between green primary activities and economic and socio-ecologic performance. While a positive relationship was observed between green external support activities and economic performance, a positive relationship was observed between green internal support activities and both economic and socio-ecologic performance.展开更多

One of the ongoing discussions in urban lake governance in India is the revitalization of the urban lakes. The core challenge documented in the governance of urban lakes is to address and find balance in the changing and competing value systems. Effectively addressing the change （or priority） in the values linked to the governance systems is a major step toward sustainability of the urban lakes. There is still limited understanding of how the values of urban lakes are progressively linked to the social, ecological and economic values of the urban developments. The paper looks at the interactions and outcomes of the spatial and temporal dynamics of the urban lakes systems especially the values that sustain the institutional and ecological memory. The focus is on the role of values in urban lake governance. The multitier framework for analyzing social-ecological systems CSES） which is in developmental phase at Elinor Ostrom＇s Workshop is used as the guiding framework to build understanding of the urban lake governance in Ahmedabad, India and at the same time contribute to the development of the SES framework.展开更多
