    STAIN: Play with solutions to design resilient cities

    STAIN is a gamified tool that enables the design of city resilience strategies in multi-stakeholder analyses in an early process phase. It emphasises the role of local knowledge and personal interpretation of resilience and combines it with city data and risk data to improve the quantification of resilience. Each user contributes to the resilience database. This database is used by each user to learn from other cities and is used to derive and improve resilience quantification as the database grows with each designed strategy.

      Zero-energy, low-cost residential wastewater treatment system: Increasing resilience in communities

      The disposal of untreated wastewater effluents coming from residential areas with no sewer connection is a common practice. This work shows results of the operation of a microbial fuel cell (MFC) stack system in a residential unit. The configuration of the system is as follows:

      i) septic tank primary treatment
      ii) chamber for secondary treatment containing 18 MFCs, coupled to an energy-harvesting circuit, and
      iii) gravity-driven disinfection (sodium hypochlorite 5%).

      After 60 days of operation with an average flow rate of 600 ± 100 L∙d−1, the system had removal efficiencies of 86% ± 10.5 for chemical oxygen demand (COD), 87% ± 16.7for biochemical oxygen demand (BOD), 84% ±5 .2 for total nitrogen (TN) and 64% ± 5.0 for total phosphorus (TP). Water quality of the treated effluent complied regulations for discharge in protected estuaries in Mexico. A cost analysis showed that the system is competitive as a sustainable and energy-efficient technology for domestic wastewater treatment.

        What explains the distribution of Non-Governmental Organisations’ water and sanitation interventions in the informal settlements in Nairobi City?

        Informal Settlements in Nairobi City fall within water and sanitation services coverage of Nairobi City Water and Sewerage Company. Nevertheless, the utility lacks sufficient investment funds leading to inadequacy of services, poor living standards and disease outbreaks in slums. These conditions attract alternative investments from Non-Governmental Organisations(NGO) in the form of water and sanitation interventions. However, the interventions are only concentrated in certain (locations of) informal settlements leading to inequity in access of water and sanitation services. Therefore, the research was aimed at discovering what explains the distribution of NGOs water and sanitation interventions in the informal settlements in Nairobi City? The researcher examined three water interventions implemented by Umande Trust (one of the key NGOs in Nairobi’s Informal settlements). This was carried out through literature review, semi-structured interviews, focus group meetings and direct field observations.

          Measuring The Benefits Of Nature-based Solutions In Urban Contexts Through Quantitative Assessment Frameworks

          A comprehensivereview of the many existing (and still under development) assessment frameworks and indicators for quantifying the multitude of benefits arising from nature-based solutions (NbS) in urban contexts. This includes an evaluation and cross-comparison of tools using multi-criteria analysis as well as the application of the highest-scoring tool on an urban NbS case study in the Netherlands. The focus of the study is primarily on water-related ecosystem services however additional biophysical benefits are also considered.
