Title: Flood Risk Mapping for Effective Mitigation in Lavun Local Government Area, Niger State, Nigeria Authors: Ahmed, Yusuf; Tasi’u, Yalwa Rilwanu; Ishaq, Abdulmuakhkhir Bala; Waziri, Aliyu Mahmood; Muslim, Musa Yakubu Abstract: Flood disaster is a common phenomenum in the study which frequently occur and need to be investigated. The study aimed at identification and Map out of flood vulnerable areas in Lavun Local Government Area for effective mitigation strategy. Two FGD were conducted in each of the selected four (4) communities while total number of eleven male (20 to 40 ages) and seven of 50 years above were interviewed. Field measurement, GIS and Remote Sensing were also used in obtaining the data. The result from the classified DEM shows that about 593.10km2 (21.76%) of the area is on highly risk and 362.58km2 (13.31%) on no risk. findings from the FGD reveals that flooding have devastating effects on the schools, clinics, roads and destruction of properties in the communities. The work concluded that, settlements are on the increase towards the floodplain which implies an increasing risk of the built-up areas, farmlands, life and properties to flooding. It was recommended that, the floodplain maps should be used in the structural design of drainage and other flood preventive measures, in communities that are at very high risk.

Title: Mapping Of Flood Vulnerable Areas In Lavun Local Government Area, Niger State, Nigeria Authors: Ahmed, Yusuf; Tasi’u, Yalwa Rilwanu Abstract: Flood disaster is a common phenomenum in Lavun Local Government area, hence this examines and map flood vulnerable areas in order to attain an efficient and effective flood mitigation plan in Lavun Local Government Area of Niger State. Two FGD were conducted in each of the selected four (4) communities while total number of eleven male (20 to 40 age) and seven of 50 years above were interviewed. Rainfall data for the period of 30 years was downloaded from a website (Era – Interim). Quantitative data like Field measurement, GIS and RS were also used in obtaining the data and descriptive analysis was used to analyse the data. The Digital Elevation Model (DEM) result shows that, communities in lower elevation are located at the eastern and south eastern part which makes them more vulnerable to flood because they are in low elevation and more close to River Gbako. Furthermore, findings from the FGD reveals that the causes of the flooding are found to be, excessive rainfall, river back flow, discharge and over flow of Shiroro Dams. The wok concluded that communities in lower elevation are located at the eastern and south eastern part which makes them more vulnerable to flood and shows that activities like dam construction (spill-water from the major river) and back flow of the river, excessive rainfall, building and farming activities on flood plain in the study area. It was recommended that, the communities that are discovered to be highly vulnerable to flood should be relocated.

Title: Impacts of Flood in Manta and Galadima Kogo Communities, Shiroro Local Government Area, Niger State, Nigeria Authors: Waziri, Aliyu Mahmood; Ishaq, Abdulmuakhkhir Bala; Ahmed, Yusuf; Umar, A.; Muhammed, Mairo Abstract: Flooding is a catastrophic hydro-climatological disaster causing destruction to thousands vulnerable communities worldwide. The aim of this study was to examine the causes of flood in Manta and Galadima Kogo communities, Shiroro Local Government Area, Niger State, Nigeria. The study adopted purposive sampling techniques in which two communities (Manta and Galadima Kogo) located in the flood prone area were selected for investigation through the application of Taro Yamane formula with 0.05 degree of freedom. A total of 400 questionnaires were administered to the respondents, and 34 years rainfall data were generated from Era5website. The data were subjected to statistical analysis using SPSS version 20.0 software. Results revealed that; an overflow from dam, heavy rainfall, human activities such as farming along the river banks and the flood plain scored 3.54, 3.27, and 3.12 respectively, and this contribute extremely to flooding in the study area, while inadequate vegetation cover and deforestation along the river banks had scored 2.51 and were regarded less serious contributing factors to flood occurrence in the study area. Destructions of crops and displacement of people were the major impacts of floods in the study area with Mean Score of 4.07 and 3.31 respectively. The study concludes that an overflow from dam, heavy rainfall and human activities such as farming along the river banks contribute extremely to flooding in the study area. The study therefore, recommends adoption of early warning system and flood forecasting for more effective mitigation strategies to flood disaster in the study area.

Title: Assessment for the Influence of Land Use and Land Cover Changes on Flood in Lavun Local Government Area, Niger State, Nigeria Authors: Ahmed, Yusuf; Tasi’u, Y. R; Waziri, Aliyu Mahmood; Ishaq, Abdulmuakhkhir Bala Abstract: Flood disaster is a common phenomenum in the study which frequently occur and need to be investigated. The study aimed at identification and Map out of flood vulnerable areas in Lavun Local Government Area for effective mitigation strategy. Field measurement, GIS and RS were also used in obtaining the data. Land use and land cover of the study area between 1990 to 2020 Image processing was carried out to manipulate and interpret digital data which involves some basic operations namely; image enhancement to increase the interpretability of features by increasing apparent contrast among various features, image classification on the other hand is assigning each pixel to a given class. The data were analyzed using supervised classification. The result shows that, built-up areas have been on increase from 163.85 km2 (5.77%) in 1990 to 433.34 km2 (15.24%) in 2020. The work concluded that, settlements are on the increase towards the floodplain which implies an increasing vulnerability of the built-up areas to flooding. It was recommended that, the communities that are discovered to be highly vulnerable to flood should be relocated and discouragements of future settlements in flood prone areas.
