“…Other literature indicates the financial burdens of relocating including costs of a new home or uncertain employment opportunities [ 34 , 45 ]. Our study supports findings from both literature that associates financial burdens with staying and those that associate financial burdens with relocating [ 34 , 44 , 45 ]. Though almost all our participants in our study had flood insurance, individuals who experienced flash flooding may be constrained to stay unwillingly and others to leave unwillingly, by several factors related to insurance, employment, and/or costs of rebuilding, as evidenced through quotes by the participants.…”

Ellicott City, MD was devasted by flash flooding in 2016 and 2018. A lack of qualitative research has been conducted on topics related to sense of place and flash flooding, especially in the United States. In this study, we reveal reasons why some who experienced flash flooding continued to stay the flood zone and why some leave. We utilized a phenomenological approach to answer these research questions. Data were generated through in-depth interviews with 19 participants from the Historic District and adjacent neighborhoods in Ellicott City. The most common reasons participants stayed were: (1) Community Impact, (2) Historical Land, and (3) Financial Burden. The most common reasons participants left were: (1) Emotional Exhaustion and Frustration, (2) Fear/Anxiety, and (3) Financial Burden. The results of our study indicate that reasons individuals who experience flash flooding stay, or leave may include community/historical, environmental, emotional, and economic factors. This reveals the complexity of relocation and sense of place after natural/environmental disasters and supports previous literature that suggests tailored response efforts based on these unique set of burdens. This paper aims to identify burdens and understand flood victims’ decisions to help policy makers improve flood response efforts.

“…From the 2000s onwards, there was a return of rainfall (Sene and Ozer, 2002;Bodian, 2014;Nouaceur, 2020) that caused a series of floods in Dakar (Bottazzi et al, 2018). Since then, these floods have occurred with near-annual frequency, and some are particularly disastrous with impacts prolonged over time (Hungerford et al, 2019). In 2012, for example, they had a serious impact on the population, resulting in 26 deaths (Sané et al, 2016) and causing pandemics such as cholera and malaria (Magny et al, 2012;Sambe-Ba et al, 2013).…”

Abstract. With the recurrence of flooding in African cities, there is growing interest in the development of sufficiently informative tools to help characterize and predict overflow risks. One of the challenges is to develop methods that strike a compromise between the accuracy of simulations, the availability of basic data, and the shortening of calculation times to be compatible with real-time applications. The present study, carried out on the urban outskirts of Dakar, aims to propose a method capable of modeling flows at fine resolution (5 m2), over the entire area, and providing a rapid diagnosis of how the drainage network is operating for rainfall intensities of different return periods, while taking urban conditions into account. Three methodological steps are combined to achieve this objective: i) determination of drainage directions, including modifications induced by buildings, artificial drainage and storage basins, ii) application of a hydrological model for calculating flows at the outlets of elementary catchment, iii) the implementation of a hydraulic model for propagating these flows through the drainage network and a storage model for retention basins. The network overflow points are calculated as the difference between the calculated flows and the network’s capacity to evacuate them. Simulation results show that the stormwater drainage network is capable of evacuating runoff volumes generated by rainfall with a low return period (10 years), but seems to overflow for rainfall with a rare frequency (100 years), with overflow rates sometimes exceeding 18 m3/s. The model, built on the ATHYS modelling platform, also provides boundary conditions for applying more complex hydraulic models to determine the local impact of drainage network overflows on limited areas.

“…Seven of the studies extracted found an increase in adverse self-reported health outcomes or an increase in the perception of health risks [72][73][74][75][76][77]. A study in Burkina Faso found that perceptions of climate impacts on health included food security, vector-borne diseases, water-related illnesses and respiratory diseases [73].…”

The Sahel region is projected to be highly impacted by the more frequent hazards associated with climate change, including increased temperature, drought and flooding. This systematic review examined the evidence for climate change-related health consequences in the Sahel. The databases used were Medline (PubMed), Embase (Ovid), Web of Science (Clarivate) and CABI Global Health. Hand searches were also conducted, which included directly engaging Sahelian researchers and hand-searching in the African Journals Online database. Of the 4153 studies found, 893 were identified as duplicates and the remaining 3260 studies were screened (title and abstract only) and then assessed for eligibility. A total of 81 studies were included in the systematic review. Most studies focused on vector-borne diseases, food security, nutrition and heat-related stress. Findings suggest that mosquito distribution will shift under different climate scenarios, but this relationship will not be linear with temperature, as there are other variables to consider. Food insecurity, stunting (chronic malnutrition) and heat-related mortality are likely to increase if no action is taken owing to the projected impact of climate change on environmental factors and agriculture. Seventy-one per cent of manuscripts ( n = 58) had first authors from institutions in North America or Europe, of which 39.7% ( n = 23) included co-authors from African institutions.
