“…Meerow, Newell and Stults mention that urban resilience refers to the ability of an urban system to adapt when facing a disturbance and to "adapt to change and to quickly transform systems that limit current or future adaptive capacity" [48]. To Bertilsson et al, the "combination of climate change and increasing urbanization brings great challenges to planning and managing cities for sustainability" [49]; therefore, there is a need to think about integrated systems that manage to absorb changes and that can dynamically accept different equilibrium possibilities (or maintain ecological resilience). All planning should bring porous contestable limits between mutually dependent forces (the economy, society and nature, keeping the flexible balance) [6].…”

The historical downtown areas are places where once there was active urban life; however, nowadays the downtown areas are busy zones by day and empty dangerous spaces by night. It is crucial to study urban centralities to understand how to make cities more sustainable; it is vital to occupy areas already endowed with consolidated urban infrastructure rather than expand cities to suburban areas. The case of Downtown Manaus is quite similar to other cities, mainly because it has been systematically vacant, as research has shown. The main objective of this project is to reclaim this area for housing plus other mixed occupation, such as commercial, leisure and housing uses. The research methodology approach was theoretical-conceptual and empirical. As a result, the survey of vacant lots aimed identify each of the lot conditions and qualities. The investigation showed that many lots have a special appealing for housing. The proposal of small residential areas using the Pod Houses and a mixed-use approach, where residents can also use the space for commercial exploration, suits the focus on multiplicity within a city. Finally, on the public realm, repossession tactics focused on parks, bridges and parking lots aiming to recover degraded areas.

In Sahelian countries, a vast number of people are still affected every year by flood despite the efforts to prevent or mitigate these catastrophic events. This phenomenon is exacerbated by the incessant population growth and the increase of extreme natural events. Hence, the development of flood management strategies such as flood hazard mapping and Early Warning Systems has become a crucial objective for the affected nations. This study presents a comprehensive hazard assessment of the Nigerien reach of the Sirba River, the main tributary Middle Niger River. Hazard thresholds were defined both on hydrological analysis and field effects, according to national guidelines. Non-stationary analyses were carried out to consider changes in the hydrological behavior of the Sirba basin over time. Data from topographical land surveys and discharge gauges collected during the 2018 dry and wet seasons were used to implement the hydraulic numerical model of the analyzed reach. The use of the proposed hydraulic model allowed the delineation of flood hazard maps as well the calculation of the flood propagation time from the upstream hydrometric station and the validation of the rating curves of the two gauging sites. These significative outcomes will allow the implementation of the Early Warning System for the river flood hazard and risk reduction plans preparation for each settlement.

“…The UFRI proposition makes it possible to build resilience maps and, consequently, to work to reduce risk consequences over time, especially regarding avoided losses. It is based on the index presented as S-FResI in Bertilsson et al [52], and was expanded in this work. The UFRI combines three sub-indexes, representing the three properties of resilience cited by Proag [57]:…”

“…In the present work, a new index, the Urban Flood Resilience Index (UFRI) [50,51], which is an evolution of the work of Bertilsson et al [52], is used to substitute the FRI in the Adapted Flood Resilience Index (aFResI), in an integrated composition built to compare the resilience behaviour over time, from the current situation to future scenarios. The new adapted method also revises the mathematical formulation of the original proposition.…”

In urbanized plains that are subject to flooding, the socioeconomic aspects, climate characteristics, built environment, and riverine processes exhibit bi-univocal relationships with the flood formation itself, creating a pattern of development without a predefined equilibrium state. The complexity of processes involved in flood management and the need for a comparative assessment method to hierarchise different design alternatives or planning scenarios requires practical and quantitative methods for urban diagnoses, including flood risk and resilience aspects. This paper proposes an alternative pathway to evaluate design alternatives for urban flood mitigation, assessing resilience in quantitative terms. In this way, a methodological framework is presented suppress to evaluate flood resilience in urban watersheds planning, through the application of the Urban Flood Resilience Index (UFRI) and Future Scenarios Criteria (FSC). A case study illustrates the method using an urban watershed in Rio de Janeiro/Brazil. This study considered two possible design alternatives for flood control, with concentrated and distributed measures. The resilience mapping using the UFRI showed that the adoption of distributed measures could increase the areas classified as showing very high resilience by 41%, while very low resilience areas would be reduced by 87%. The FSC is able to present the integrated results of resilience variation from present and future conditions, considering, for example, climate change effects or unplanned urbanisation scenarios. The framework is able to perform comparisons between alternatives, showing the advantages associated with adopting distributed measures over the watershed, which reflected in a resilience value that was 24% higher when compared to the results obtained for the concentrated solutions scenario.
