Sustainable Use of Recycled Plastics and Construction and Demolition Waste in Hydraulic Concrete for Civil Works : Mitigating the Climate Emergency View Digital Media
Paper Presentation in a Themed Session Henry Mauricio Muñoz Trochez, Ferney Quiñones Sinisterra
In recent years, environmental policies have generated the search for technical solutions to reduce the effects of the climate emergency and environmental pollution, leading to the investigation of innovative alternatives that can contribute in this direction. This study considers new options in civil works, such as the incorporation of plastic waste (PW) and construction and demolition waste (CDW). PW and CDW have been transformed into the most generated waste in the planet, becoming a focus of environmental contamination in the different cities of the world. For this reason, methodologies are proposed for the correct use of these wastes within hydraulic concrete, which is the most used manufactured construction material by humanity. In this research, laboratory tests and procedures were carried out to determine the PW optimal dosage, evaluating the physical and mechanical characteristics required to be used in pavements, buildings, highway civil works, infrastructure and public space. This work presents important contributions that can be implemented anywhere in the world, using clear, low-cost methodologies and with efficient results, it also contributes significantly in reducing the global climate emergency and environmental pollution. Finally, this work allows generating policies and regulations for the reuse of plastic waste and CDW in the elaboration of hydraulic concrete for civil works in countries or regions that do not have this type of policy.
Pursuing Water Security: A Network-based Metagovernance Approach to Address Complexity in Adaptive River Basin Management View Digital Media
Paper Presentation in a Themed Session Natalia Julio, Roberto Ponce Oliva, Ricardo Figueroa
Water Security (WS) is a desirable goal to ensuring the adequate quantity and quality of water for life-supporting processes and determining factor in society’s development. Reaching WS is a complex problem that must be solved in an integrated and interdisciplinary way. Integrated River Basin Management (IRBM) could be a means to achieve WS as long as it is supported by the development of an appropriate adaptive governance process, which emphasizes more collaborative and coordinated actions and recognizes river basins as complex social-ecological systems. In this paper, we analyze the relationship between WS and the hybrid conceptualization of hierarchical, market-based and network-based governances, namely metagovernance. We propose a form of “network of networks” as an effective approach to implement adaptive river basin management to facilitate an adequate quantity and quality of water for all sector needs. Since adaptive governance literature promotes the adoption of network structures and polycentrism, we argue that a “good water governance” approach implies the adoption of a network-based metagovernance system, in which both markets and hierarchies are embraced by networks as the most general category of coordination. Here, the role of metagovernors is key to avoid typical failures resulting from the exclusive application of network-based governance. In this sense, river basins as social-ecological systems must be regarded as networks as well, since social and ecological variables are interconnected and integrated trough a governance system observed at multiple scales. Further research is needed to achieve better coordination of multiple centers of decision-making and to best address context-specific strategies.
Decarbonization Process in Chile: From Conflict to Social Consensus View Digital Media
Paper Presentation in a Themed Session Claudio Huepe
This research analyses the evolution of energy policy in Chile regarding the reduction of greenhouse gas emissions since 2000, in particular the complexities of speeding up the transition. The policy decision process is studied in relation to changes in the energy market, energy crises and citizens' protests. The analysis searches an understanding of the factors that determine policy adjustment to the interests of the various actors and how these interests are reflected in policy, strategies general legislation and specific regulations. Faced with a growing citizen demand for cleaner energy, significant changes can be observed in the process of public policy formulation in recent years, with more participation of civil society and more negotiation with companies. In particular, there has been a move from a strictly technocratic perspective, especially within the Ministry of Energy, towards one which integrates the interests of relevant actors while advancing towards more cooperation between actors and less conflict. To explores this issue, over twenty interviews are carried out with actors that played a role during this turn from a government that is strictly a technical and economic regulator of the energy market towards one that has environmental and social goals and is open to citizen participation.
