- ItemAportes y desafíos del Sistema de Evaluación de Impacto Ambiental (SEIA) a la conservación de la biodiversidad en Chile(Interuniversity Institute of Geography and University of Alicante, 2019) Henríquez Ruiz, Cristian Gonzalo; CEDEUS (Chile); Pontificia Universidad Católica de Chile. Instituto de GeografíaEnvironmental impact assessment systems are preventive management instruments whose main objective is to include environmental considerations in the processes and activities accompanying economic growth in a nation. The influence of these systems in the conservation of biodiversity is fundamental, since within the evaluation process, they enable identifying and evaluating potential environmental impacts, as well as defining reparations, compensations, or mitigations. Halting the loss of biodiversity caused by human activities and climate change is a global objective. Chile is also facing this challenge, considering its status of Biodiversity Hotspot, projections associated with climate change, and the outstanding issues that the Environmental Impact Assessment System (SEIA) shows regarding biodiversity conservation. The latest, based on the lack of strategic view when considering issues such as the territorial scope of the environmental impacts generated by the projects, under a systemic and transversal approach. This research analyses the main changes experienced since the creation of SEIA, and compares this system with other evaluation systems used in Latin America. National statistics on investment projects potentially affecting the conservation of biodiversity are given. Two issues are addressed to guide discussion of the operational changes that should be encouraged by the Chilean government, namely: 1) internalising the importance of protecting biodiversity beyond current regulations, and; 2) introducing improvements in environmental legislation that could indirectly lead to improvements in SEIA. The research concludes on the importance of strengthening the Strategic Environmental Assessment (SEA) and its integration with the SEIA, in order to encourage better project designs by including sustainability from the beginning.

- ItemChallenges and opportunities for drinking water treatment residuals (DWTRs) in metal-rich areas: an integrated approach(2022) Briso, Alejandro; Vega, Alejandra; Molinos Senante, María; Pasten Gonzalez, Pablo Arturo; CEDEUS (Chile)The physicochemistry and production rate of drinking water treatment residuals (DWTRs) depends on the raw water composition and the plant operational parameters. DWTRs usually contain Fe and/or Al oxyhydroxides, sand, clay, organic matter, and other compounds such as metal(oids), which are relevant in mining countries. This work proposes a simple approach to identify DWTRs reuse opportunities and threats, relevant for public policies in countries with diverse geochemical conditions. Raw water pollution indexes and compositions of DWTRs were estimated for Chile as a model case. About 23% of the raw drinking water sources had moderate or seriously contamination from high turbidity and metal(loid) pollution If the untapped reactivity of clean DWRTs was used to treat resources water in the same water company, the 73 and 64% of these companies would be able to treat water sources with As and Cu above the drinking water regulations, respectively. Integrating plant operational data and the hydrochemical characteristics of raw waters allows the prediction of DWTRs production, chemical composition, and reactivity, which is necessary to identify challenges and opportunities for DWTRs management.

- ItemCompensating Water Service Interruptions to Implement a Safe-to-Fail Approach to Climate Change Adaptation in Urban Water Supply(2020) Undurraga, Rafael; Vicuña, Sebastián; Melo Contreras, Óscar; CEDEUS (Chile)A city resilient to climate change is characterized by effectively responding to and recovering from the negative impacts of climate hazards. In the city of Santiago, Chile, extreme weather that can be associated with a nascent manifestation of climate change has caused high-turbidity events, repeatedly forcing the main water company to interrupt the supply of drinking water, affecting millions of people. This study proposes a transformative response to reduce harm from extreme events due to climate change. The traditional approach of increasing resilience through large infrastructure works can be complemented by one-off reductions in water use during emergencies, in exchange for economic compensation. This alternative seeks to transfer the individual responsibility of water companies to a collective one, where the community is an active agent that reduces damage in the face of extreme events resulting from climate change. In the assessment of this response, we used a choice experiment to estimate the minimum amount users are willing to accept in compensation for water service interruptions. The results show that willingness to accept compensation is significant (close to 0.6 USD/hour) and decreases when users have experienced additional unplanned interruptions. The aggregate cost of the compensation is lower than infrastructure investments required to avoid service interruptions under various future hypothetical hydroclimatic scenarios associated with climate change impacts. Therefore, compensation-based instruments for water service interruptions could be a more flexible and cost-effective alternative to infrastructure-based measures to cope with future climate hazards.
