Situated in South America, Chile possesses diverse natural ecosystems (deserts, mountain ranges, glaciers) that are affected by its economic activities.…”

Effective DRM aims to identify and minimize both hazards and vulnerabilities of a territory. This case study carried out in Chile analyzes national programs and disaster risk management structures at different administrative levels (national, regional, and municipal) and identifies gaps that contribute to the vulnerability of the current system. The proposed measures and options for improvement presented in this study are based on a literature review of scientific discussions about international governance, disaster risk management, and case studies conducted in Chile. The results indicate that the national disaster risk management plan has been adjusted in recent years, especially after the 2010 Chilean earthquake. The national administration, which is primarily responsible for managing potential risks, as well as the regional and local governments, has been replaced by the National Disaster Prevention and Response System (SINAPRED) in 2021, according to the 21364 law. This law was created to make cities more resilient, contributing to the Sustainable Development Goals (SDGs). This change is intended to decentralize disaster risk management, considering local conditions and preventing oversight of disaster risk management, which is not mandatory at the local level. It has also noted some gaps, such as the lack of standardization of emergency and early warning systems and funding at local levels. It is hoped that the system will move forward in this transition period and that the gaps will not affect effective risk management, as they have caused loss of life in past disasters.

The provision of an efficient water supply service (WSS) is crucial for the well-being of citizens and the sustainability of cities. This study aims to evaluate the performance of WSS using the results of a household survey and the ranking of performance indicators (PIs) by the analytic hierarchy process method. The methodology developed was tested for the case of the city of Taoura (Algeria). A survey was carried out among 340 residents of the city. The survey results showed that the majority of respondents (70%) were relatively dissatisfied with the quantity of water provided and 67% of households surveyed rated the quality of service as poor. Then, the performance was evaluated according to 5 decision criteria and 20 PIs. The results of the evaluation of the relative weights of the criteria are as follows: the ‘Financial and economic’ criterion plays the most important role, with a relative weight of 38.61%, followed by the ‘Operational’ criterion (24.7%) and the criterion ‘Physics’ (17.32%). The methodology used in this study can be a reliable tool for evaluating the performance of WSS in developing countries.

This research article explores the use of the Analytic Hierarchy Process (AHP) as a decision support tool for evaluating and rehabilitating the water distribution network in Mila City, Algeria. The study identifies key challenges, such as water loss, infrastructure deterioration, and inadequate service delivery. By employing AHP, the researchers systematically prioritize various performance indicators, including water quality, pressure, and operational efficiency. Data is gathered from field assessments and stakeholder interviews to develop a hierarchical model that reflects the network's critical factors. The findings demonstrate that AHP facilitates informed decision-making by allowing stakeholders to weigh different rehabilitation options effectively. The results indicate that targeted investments can significantly improve the system’s performance. The AHP method has revealed that the performance of the "network condition" criterion is around 36%, and the performance of the "customer complaint handling" criterion is 0.49, indicating that the network is in poor condition. On the other hand, the performance of the "physical-chemical quality of the distributed water" is approximately 80%. Overall, the performance of the distribution network is average at about 50%, suggesting the need for renovation to improve its efficiency and functionality. The study emphasizes the importance of integrating AHP into water management practices, suggesting that it can enhance the sustainability and reliability of water services in Mila City. The conclusions provide actionable recommendations for local authorities and utility managers to guide future rehabilitation efforts, contributing to improved water resource management in Algeria.
