“…Meanwhile, it has been observed that the literature is sparse in many critical areas of flooding and FRM for Nigeria. For instance Egbenta et al [2] observed that there is a paucity of information on the effects of flood hazard on the values of properties in Nigeria while Nkwunonwo et al [7] asserted that only journalistic and non-quantitative evidence are available on some critical aspects of flooding in Nigeria. A recent review by Komolafe et al [3] highlighted the absence of the use of state of the art flood models integrating all hydrological processes for accurate prediction and mapping of flooding and its associated risks in Nigeria.…”

Flooding has become a major hazard in Nigeria in recent years due to a growing population, rapid urbanization and extreme weather events. This study provides a critical review and characterisation flood risk management (FRM) practices in Nigeria with a view to highlighting current weaknesses and opportunities, as well as giving recommendations for practice and for further research. Databases of academic literature, covering a wide range of FRM issues, were systematically queried and mined using suitable keywords. A structured review of the resulting literature was carried out and several past flood events and associated responses reviewed as case studies. Absence of integrated FRM systems, lack of inter agency coordination, substandard and weak infrastructures, inadequate drainage network, high urban poverty, low level literacy, cultural barriers and weak institutions characterize current FRM practices. The study recommends the adoption of an integrated approach to urban infrastructural development starting with a review of ongoing and planned infrastructural systems and projects with a view to optimizing their FRM capabilities while still meeting their intended purposes. The empowerment of more entrepreneurs into FRM solutions development and service delivery as well as the inclusion of FRM concepts and practices into the nation's educational curricula was also recommended. Nigeria also needs a multidisciplinary platform for generating effective strategic policies and efficient operational mechanisms for FRM.

“…The main limitation of these field data is the insufficient spatial and temporal coverage, due to a limited number of observations across the area and the lack of repetition of the data acquisition over time (Townsend & Walsh, 1998) as well as the financial cost for maintenance and data processing (Houghton-Carr, 2014). The situation is worse in developing countries where other factors, such as political and institutional instabilities occurring at national or regional level (Lins, 2008) or the dependency on international aid (Hannah et al, 2011) impede the installation and the maintenance of monitoring instruments (see, for example, Nkwunonwo, Whitworth, & Baily, 2015;Komi, Neal, Trigg, & Diekkrüger, 2017).…”

Flood hazard assessment is at the core of flood risk management. In order to develop an efficient flood hazard assessment, it is of primary importance to have a well‐defined flood scenario encompassing all processes that could occur during an event. Understanding and assessing these processes requires meteorological, topographical and land‐use data as well as historical observations. Nowadays, flood delineation is based upon hydrological and hydraulic modelling, ground data collection, and remote sensing. Despite the advantages of these tools, they also present some specific limitations, either intrinsic to the approaches or linked with constraints of the local context. With the rapid advancement of web 2.0 technologies (e.g., Flickr and Wikimapia) and the increase of the use of participatory research, citizen science has the potential to provide valuable and complementary information at all levels of flood risk management and in particular for flood hazard assessment. After reviewing the capabilities and limitations of the current tools used in flood hazard assessment, this paper demonstrates the role that citizen science can play in providing key information on factors leading to flooding and on flood hazard parameters.

“…In the event of crises, these agencies coordinate activities ranging from rescues and recovery to building back for victims. In the DCs, it is argued that these agencies are weak while their roles are not clearly defined (Nkwunonwo et al, 2015b). Similarly, technical capacity is insufficient.…”

“…Structural measures such as chennelisation of various canals, bridges, culverts and drainage systems to evacuate more storm water are acknowledged (Adelekan, 2015). Humanitarian aids (from for examples: Religious bodies, international communities, the United Nations, foreign agents), have been prominent all along (Nkwunonwo et al, 2015b). Local planning authorities legislate against illegal structures and enforce that more building conform to local building standards.…”

Of all the widespread natural hazards with large scale human, economic and environmental impacts, flooding surpasses. In the urban areas, the threats of this hazard are substantial and call for ever more attention, which, within the contexts of sustainable human and urban development, is increasingly an important problem in social science research. Urban flooding is a relatively new hazard phenomenon, which is progressively galvanising significant concerns globally due to the economic and political significance of cities. Flood risk management, based on the UNISDR idea of living with floods rather than fighting them, provides systematic techniques for tackling this hazard. However, the insufficiency or lack of the pertinent capacities, which are fundamental to best practices in flood risk management, undermine these techniques in many developing countries (DCs), such as Nigeria and Bangladesh. This study, through a desktop review of various published materials, focusing on urban flooding and management experiences in Lagos, Dhaka and Maputo, explores the lack of these capacities. Among other issues, the idea of resilient cities and communities as well as sustainable urban development will be realistic in the DCs only if adequate attention is given to capacity development.
