Human factors vs climate change; experts’ view of drivers of flooding in Nigeria

Natural Hazards Research, Journal Year: 2023, Volume and Issue: 3(2), P. 240 - 246

Published: April 26, 2023

Flooding disasters are occurring more frequently across the globe. Resilience capacity also differs with developing countries less able to withstand devastating impacts of flooding. The level and type action prevent or mitigate flooding is dependent on prevalent views its principal drivers. This research engages experts in field flood risk management Nigeria, Africa's most populous country where threats frequency has increased over years. An in-depth qualitative case study was conducted semi-structured interviews used as primary data collection tool. Understanding distinguishing core drivers according context pertinent because a situation deemed be factors beyond human control, there little action. this acknowledged influence climate change which led increase rainfall intensity, duration. However, they attributed being experienced location due controllable including lack infrastructure, poor urban planning governance, weak implementation enforcement laws policies. A mix structural non-structural solutions were recommended better manage achieve goal sustainable cities settlements.

Decadal mapping of flood inundation and damage assessment in the confluence region of Rivers Niger and Benue using multi-sensor data and Google Earth Engine

Journal of Water and Climate Change, Journal Year: 2024, Volume and Issue: 15(2), P. 348 - 369

Published: Jan. 30, 2024

Abstract Climate change has made weather patterns more extreme, causing floods in Nigeria. Flooding is the most frequent and serious natural hazard confluence region of Rivers Niger Benue, impacting lives, agriculture, socio-economic activities significantly. Advancements satellite technology computational capabilities have enhanced rapid information about flood extent for monitoring, mitigation, planning. However, there a dearth based on time series analysis inundation monitoring region. In this study, Sentinel-1 Synthetic Aperture Radar, Sentinel-2, Landsat-7 Landsat-8 data were used to extract 10 years (2012–2022) Benue. Flood extent/surface waterbodies extracted using Google Earth Engine platform, modified normalized difference water index, index methods. The findings revealed that within years, four significant flooding incidents occurred 2012, 2018, 2020, 2022, inundating 60.57, 48.24, 39.98, 84.39 km2 area, respectively. study underscores need establishment decision support system providing decision-makers necessary disaster preparedness, adaptation.

Published: May 1, 2025

Flooding has increasingly significant adverse effects on global food security, and there is a lack of framework to effectively integrate remote sensing with survey data for accurate damage recovery assessment. Also, optical satellite images flood mapping face cloud interference, free synthetic aperture radar (SAR) the temporal frequency needed capture flooding dynamics. This study developed new modelling crop damage, loss, due flash using time-series multi-sensor images. Crop from was validated extensive participatory data. were assessed during Nigeria's 2020 2022 floods. Consistency found between farmer-reported losses sensing-based assessments: 91 % farmers reporting total loss had no recovery. Flood maps assessments achieved over 90 accuracy, demonstrating reliability multi-source SAR combined machine learning technique. Severe evident, only 13 16 flooded cropland recovered in 2022, respectively. The integrated approach this eliminates uncertainties other techniques, overcomes limitations, offers scalability national-level implementation, providing critical information post-disaster planning, farmer compensation, sustainable agricultural practices enhance security changing climate.

Climate Change Mitigation Perspectives from Sub-Saharan Africa: The Technical Pathways to Deep Decarbonization at the City Level

Atmosphere, Journal Year: 2024, Volume and Issue: 15(10), P. 1190 - 1190

Published: Oct. 4, 2024

The complex and multidimensional effect of climate change, coupled with low socioeconomic development, in Sub-Saharan Africa (SSA) makes the region vulnerable to changing threatens its inhabitants’ survival, livelihood, health. Subnational actions have been widely acclaimed as effective combatting change. Local governments SSA developing implementing action plans reduce greenhouse gas (GHG) emissions. In this article, we qualitatively assessed change mitigation technical pathways at city level by studying four major African megacities’ actions. cities studied are Accra, Ghana; Addis Ababa, Ethiopia; Lagos, Nigeria; Nairobi, Kenya. This study provides insight into novel innovative policy design instrumentation options sustainably address SSA. With past literature focusing on adaptation for Global South, shows leading context-specific efforts that simultaneously local sustainable development needs. Our assessment identified prioritized selected cities, well techniques areas improvement. Given it also identifies emerging best practices, study’s findings can be helpful practitioners pursuing deep decarbonization international organizations supporting these programs.
