项目摘要

Even though access to safe drinking water and sanitation has been recognised by the United Nations as a human right, providing universal access to basic needs is still an important challenge of today, and as such was set as one of the Sustainable Development Goals (SDG) in the 2030 Agenda for Sustainable Development. Small-scale systems for water treatment can contribute to the provision of safe water in areas not served by conventional systems, such as rural or peri-urban areas. However, this context can prove itself challenging due to availability of resources, organisational support, among other critical factors. The observed moderate success of these systems derives from some important criteria not being met. The constraints that threaten the long-term functionality of the local schemes are not necessarily related to performance of the technologies, but to a series of influential factors of environmental, technical, governmental, economic or social nature. The aim of this project is to develop a decision-support framework to assess sustainability of decentralised, small-scale water treatment systems in the context of developing countries. The study will carefully investigate the multidisciplinary factors that affect the sustainability in this context. Integrating different sustainability factors such as economic, environmental and especially social aspects is crucial for providing a more comprehensive evaluation. Some well-established assessment methodologies such as Life Cycle Analysis or Cost-Benefit Analysis do not consider socioeconomic factors and would not provide a good sustainability evaluation in this context. This project will integrate different aspects using Multi-criteria Decision Analysis (MCDA) in order to simultaneously evaluate different criteria and their quantitative and qualitative attributes in one universal and holistic decision support framework, focusing on ensuring high acceptance of the decision-making process by stakeholders. The applicability of this framework will be evaluated by case studies in developing countries, where real systems will be assessed in order to find the best available alternative. The decision support tool will then provide support to stakeholders in deciding the best way forward, and hopefully helping to bring us closer to universal access to safe drinking water.

尽管获得安全饮用水和卫生设施已被联合国确认为一项人权，但提供普遍获得基本需求仍然是当今的一项重要挑战，因此被列为2030年可持续发展议程中的可持续发展目标之一。小型水处理系统有助于在农村或城市周边地区等没有常规水处理系统的地区提供安全用水。然而，由于资源的可用性，组织支持以及其他关键因素，这种情况可能会证明自己具有挑战性。观察到的这些系统的适度成功来自于一些重要的标准没有得到满足。威胁到当地计划长期功能的制约因素不一定与技术的性能有关，而是与环境、技术、政府、经济或社会性质的一系列影响因素有关。该项目的目的是制定一个决策支持框架，以评估发展中国家分散的小规模水处理系统的可持续性。这项研究将仔细调查在这方面影响可持续性的多学科因素。综合不同的可持续性因素，如经济、环境，特别是社会方面，对于提供更全面的评估至关重要。一些行之有效的评估方法，如生命周期分析或成本效益分析，没有考虑到社会经济因素，因此无法在这方面提供良好的可持续性评估。该项目将利用多标准决策分析整合不同方面，以便在一个普遍和全面的决策支持框架中同时评价不同的标准及其定量和定性属性，重点是确保利益攸关方高度接受决策过程。将通过发展中国家的案例研究来评估这一框架的适用性，在这些国家将对真实的系统进行评估，以找到最佳的可供选择的办法。然后，决策支持工具将为利益攸关方提供支持，以决定最佳前进方式，并希望有助于使我们更接近普遍获得安全饮用水。
