The impact of climate change is often demonstrated by rainfall and its attributes. Consequently, this study analyzes rainfall concentration, temporal trends, and rates of change in the savannah zones of Nigeria. Rainfall data were acquired from the archives of the Environmental Management Programme, Federal University of Technology, Minna, for 13 s...

This study evaluated the suitability of a monsoon quality index (MQI) within the timescales of 6 months and 12 months, as an alternative to the standardised precipitation index (SPI), in assessing rainfall conditions over the rainfall-sensitive, food-producing savanna zones of Nigeria. The results revealed varied correlation between commensurate ra...

This study characterised the spatio-temporal patterns of effective rainfall onset dates, their variability and their relationship with ENSO/IOD over Savanna zones of Nigeria. Daily rainfall and ENSO/IOD data for the period 1971–2015 were used. The Intra-Seasonal Rainfall Monitoring Index (IRMI) was applied to identify and classify effective rainfal...

This study aimed to examine the effects of climate variability on annual crop yield at smallholder farmers’ level in the Guinea Savanna Region of Nigeria, using Niger State as a case study. Climate data (rainfall and maximum temperature) for a period of 38 years (1971-2008) was acquired from National Cereals Research Institute, Bida and Nigeria Met...

Vegetation absorbs carbon dioxide from the atmosphere, thereby mitigating the impact of global warming and climate change and also preventing desertification. In Nigeria, desertification poses a threat to the livelihoods of numerous communities, particularly in the northern region. Consequently, this study focused on the analysis of the changes in...

This study aims to determine a relationship between power generation and hydroclimate elements. The Mann-Kendall test, Sen’s slope tests, Pearson’s correlation and linear regression have been used for data analysis. The results of monthly hydroclimate elements showed mixed increasing and decreasing trends. The annual rainfall, maximum and minimum t...

This paper assessed soil degradation over land use in the Kebbi area, Northwestern Nigeria. The specific objectives entailed identifying major forms of soil loss in the study area, estimating soil loss, and examining the responses of soil physico-chemical properties over dominant land use types. Slope angles were determined using a GPS, a handheld...

Flash droughts could increase the risk of food and water security in the semi-arid region of West Africa. It has been established that a drought would impact agriculture, particularly in West Africa, where farming is climate dependent. The conventional drought has attracted enormous research attention in the marginal environment of West Africa beca...

This study was aimed at assessing monsoonal rainfall real onset dates (RODs), real cessation dates (RCDs) and extent of association between cumulative rainfall (CR) and length of growing season (LGS) in the context of climate adaptation planning for sustainable rain-fed agriculture in the Sudano-Sahelian area of Northwestern Nigeria. Daily rainfall...

This study examines the impact of climate change on hydrologic resources of selected rivers and lakes in the Sudano-Sahelian Ecological Zone of Nigeria. Climatologically data acquired were rainfall, temperature and evaporation from Nigeria Meteorological Agency, Oshodi, Lagos. Similarly, the hydrological data of river discharge and lake levels were...

The paper aimed to demonstrate how the application of HEC-RAS and GIS techniques can be utilized for better results when carrying out a flood vulnerability mapping and assessment. Digital interpretation that uses HEC-RAS and GIS to conduct hydraulic modelling, flood inundation mapping and visualization were adapted. Similarly, Digital Terrain Model...

This study aims to determine trends in long-term monthly rainfall using nonparametric methods (i.e. the Mann–Kendall and Sen's T tests) in Gusau North-Western Nigeria. Monthly rainfall records of Gusau synoptic stations for a period 60 years (1953-2012), were acquired from the Nigerian Meteorological Agency. The result revealed that the monthly rai...

Management of solid waste is one of the challenges facing most developing countries like Nigeria where there is no substantial National Waste Management Plan. This led to the practice of open dumping system, which is not environmentally sound and socially acceptable. Considering the nature of solid waste disposal in Nigeria, there is a need to util...

A major serious source of pollution is the industrial effluent discharge by the process industries into the water bodies. Industrial effluent consists of water with varieties of potentially harmful substances. The study analysed the public health effects of effluents discharged from Kaduna textile industry into the waters of river Kaduna. Physicoch...

This research work studied the importance of water as a resource that needs to be sustained. From the study, it was realised that poor planning, inadequate funding, insufficient relevant manpower and haphazard implementation of national policy for water supply is responsible for the inadequacy of water both in quantity and quality. The major aim of...
