“…Extreme precipitation and related flooding events have both economic and human consequences which have rapidly increased over the years (Kaspersen et al, 2017). Akukwe et al (2020) asserted that flooding has the capability to make communities food insecurity hotspots and thus hamper the achievement of Goal 2 of the Sustainable Development Goals. In Nigeria, floods are the most frequent and severe natural hazards which have significantly affected lives and properties negatively (Olorunfemi et al, 2020).…”

“…Flooding is one of the most destructive widespread natural hazards of the world with a high frequency of occurrence and a huge impact on large population ( Akukwe et al., 2020 ; Zhao and Gao, 2016 ). It is a major threat to the survival of the human race with associated risks that include the destruction of lives and properties, the displacement of livelihoods, and the impoverishment of flood victims ( Okafor, 2020 ).…”

“…Flood hazard has displaced more people in the country than any other natural hazard with the population at risk estimated to be 20% ( Cirella and Iyalomhe, 2018 ). The country has experienced several flood episodes with the 2012 flood episode being tagged the most severe and devastating flood episode ever witnessed in the country over the years ( Ajaero et al., 2016 ; Akukwe et al., 2020 ; Eboh et al., 2017 ; Ezeokoli et al., 2019 ; Nemine, 2015 ; Okafor, 2020 ; Tami and Moses, 2015 ). The 2012 flood episode affected over 30 states in the country with an estimated total of seven million people affected and an economic loss estimate of 2.6 trillion naira ( Okafor, 2020 ).…”

Flooding is a major environmental problem facing Anambra State of Nigeria, which also threatens food security in the state. To address this issue, continual flood vulnerability mapping exploring more efficient methods is needed to facilitate flood risk management in the state. The advantages of employing spatial information technologies such as Remote Sensing (RS) and Geographic Information System (GIS) in flood vulnerability mapping has been widely documented; the limitations of employing GIS alone in effective vulnerability analysis have also been documented by researchers. To overcome these limitations, this study adopted the use of GIS and the integration of Interval Value Fuzzy Rough Number (IVFRN), Decision Making Trial and Evaluation Laboratory (DEMATEL), and Analytical Network Process (ANP) method in vulnerability assessment of flood hazard. The result of the study shows that the state is very vulnerable to flood with 73% of the total area of the state lying between Very High and Medium vulnerable zones. The most vulnerable Local Government Area (LGA) in the State is Anambra West with 95% of the total area of the LGA lying between Very High and Medium vulnerable zones. Furthermore, the obtained values ofR ÀD show that Rainfall Intensity factor is the major cause of flood in the study area with the highest positive value of 1.55 and Soil factor is the major effect with the highest negative value of -0.93. The IVFRN-DEMATEL-ANP assessment model was validated using AUC-ROC method; an AUC value of 0.946 was obtained, this indicates that the model has excellent prediction accuracy. This study was able to establish the feasibility of integrating the IVFRN, DEMATEL and ANP methods in flood vulnerability assessment. It is recommended that the provision of adequate drainage systems should be prioritized to areas of high flood vulnerability index; to help mitigate flood hazards in the State. Also, strategic planning of infrastructures and emergency routes for moving people and key assets from vulnerable areas especially during the rainy season should be geospatialbased and systematic.

“…Whereas average temperatures are highest in the tropics, the temperate, and polar regions have lower temperatures. Consequently, the negative impacts of climate change are worse in economically vulnerable countries than the strong economies (Akukwe et al, 2020). The impacts of floods, droughts, cyclones, tsunamis, and storms due to climate change, are more predominant in tropics than in temperate regions.…”

“…Ola (2018) focused on the challenges of climate change of rural dwellers of Esanland in Nigeria and concludes that farmers are vulnerable to the adverse impacts of climate change. With more specific emphasis on floods, Akukwe et al (2020) studied flooding as climate change hazard and its impacts on food security in southeast Nigeria. Results of their research confirmed that floods negatively affect food security by increasing the number of food insecure households in the study area.…”

This research reviews climate change, flood disasters impacts and food security nexus in northern Ghana. The impacts of climate change include flood disasters which in turn affect food production with subsequent impact on food security. While climate change impact can be positive in some regions, it can be negative in other regions as it could lead to excess or lack of water, which negatively affects food production. Most especially, flood disasters have reportedly become frequent with devastating consequences on food production. Literature further suggests that the frequency of floods and their impacts have the potential to increase in the future. Floods inundate farms, pastures and livestock, which could subsequently reduce crop yields and animal production. Floods also destroys physical infrastructure and disrupts socio-economic activities which are linked to agriculture sector and could affect food production. This eventually decreases food availability, accessibility, utilization, and stability in the region. Northern Ghana has experienced flood disasters with increased frequency, which are related to climate change impacts. Although there is research on climate change, flood disasters, and food security issues in northern Ghana, the literature thus far indicates no clear focus of studies that focuses on the nexus of climate change, flood disasters, and food security of the study site. Thus, this research seeks to review the nexus of climate change, and flood disaster impacts on food security in northern Ghana with their implications on food security in the region. This study has two main research objectives. The first objective of this research is to identify and understand the potential impacts of climate change and flood disasters on food production in the study site. The second research objective is to explain the connection between climate change and flood disasters and the implications of this relationship on food security in the study site. This review study focuses on climate change, flood disasters, and food production to understand the critical impacts of climate change and flood disasters on food security in the northern part of Ghana. The aim of this research is to contribute to literature and discussion of the nexus of climate change, flood disaster impacts and food security sub-Saharan Africa.

Objectives Flooding is the most frequent extreme‐weather disaster and disproportionately burdens marginalized populations. This article examines how food and water insecurity, blood pressure (BP), nutritional status, and diarrheal and respiratory illnesses changed during the 2 months following a historic flood in lowland Bolivia. Methods Drawing on longitudinal data from Tsimane' forager‐horticulturalist (n = 118 household heads; n = 129 children) directly after a historic 2014 flood and ~2 months later, we use fixed effects linear regression and random effects logistic regression models to test changes in the markers of well‐being and health over the recovery process. Results Results demonstrated that water insecurity scores decreased significantly 2 month's postflood, while food insecurity scores remained high. Adults' systolic and diastolic BP significantly declined 2 months after the flood's conclusion. Adults experienced losses in measures of adiposity (BMI, sum of four skinfolds, waist circumference). Children gained weight and BMI‐for‐age Z‐scores indicating buffering of children by adults from food stress that mainly occurred in the community closer to the main market town with greater access to food aid. Odds of diarrhea showed a nonsignificant decline, while cough increased significantly for both children and adults 2 months postflood. Conclusions Water insecurity and BP improved during the recovery process, while high levels of food insecurity persisted, and nutritional stress and respiratory illness worsened. Not all indicators of well‐being and health recover at the same rate after historic flooding events. Planning for multiphase recovery is critical to improve health of marginalized populations after flooding.
