This paper presents the findings of a case study that explores the existing situation of solid waste management and disposal practices in metropolitan Kano; the largest urban setting in northern Nigeria. The study was developed using various data sourced from field surveys and existing literature. It reveals the indiscriminate nature of the handlin...

Population growth and urban expansion are essential drivers of land use/land cover (LULC) changes and this has made West Africa’s rapidly growing cities, highly vulnerable to environmental change. In Nigeria, unplanned settlement and sprawl combined with inadequate infrastructure already place high stresses on natural resources. This is attributed...

This paper aimed at determining the contribution of agricultural activities to deforestation of some Nigerian forests through investigations of the crops commonly grown, management practices, impact on the environment and providing sustainable agricultural practices that farmers could adopt. Landsat images of the selected forests for the period 199...

This study was carried out to investigate the spatial variations and pollution source of the Kano-Challawa groundwater for the sustainable management of water resources. Seventy-two groundwater samples were collected from twelve sampling points (GW1-GW12) along the downstream of the Kano-Challawa River system and twenty-nine groundwater quality var...

Kaduna refinery is the third petroleum refinery in Nigeria which consists of the fuels, lubricants and petrochemical plants. An investigation was carried out on groundwater around the refinery to ascertain the presence of hydrocarbon contaminants. Twenty-six groundwater samples were collected in the dry and rainy seasons and analyzed for identifica...

This research primarily assesses the water supply and sanitation situations in Dala Local Government Area of Kano State. This is one of the most densely populated areas in Nigeria. As such, there is a considerable amount of pressure on its natural resources, especially land and water. The provision of water supply and sanitation were examined quali...

Several human activities impact negatively on groundwater resources. Kaduna metropolis, like other major cities in Nigeria, lack adequate portable water supply to cater for its growing population. Groundwater development serves as the quickest means of augmenting the deficit in water supply in the area. Threats to the groundwater quality is however...

Sahel is one of the major African drylands whose experience of recurring droughts exacerbates its vulnerability to climate change. Its population is estimated to rise to over 200 million by 2050. This region has attracted attention of the global scientific communities, and for which interventions from scientists, intergovernmental institutions, and...

Abstract DRASTIC index model was employed in the assessment of the intrinsic groundwater vulnerability to contamination in Kaduna metropolis, Nigeria. The model evaluates the contribution of seven environmental parameters (Depth to water level, Net Recharge, Aquifer media, Soil media, Topography, Impact of vadose zone, and Hydraulic Conductivity) i...

Sustainable energy supply challenges have provided key areas of concern in African cities. Considering the links between vegetation modification and woodfuel production, consumption and exchange in cities, academics and policy actors are turning attention to the matter as it forms key challenges to social and environmental sustainability. Researche...

In this work, the DRASTIC and GALDIT models were employed to determine the groundwater vulnerability to contamination from anthropogenic activities and seawater intrusion in Kapas Island. In addition, the work also utilized sensitivity analysis to evaluate the influence of each individual parameter used in developing the final models. Based on thes...

The advancement of technology today, helps in the depiction of reality for a particular phenomenon. The use of Geographical Information Systems (GIS) as part of the organization helps in development, especially when it comes to analysis and the distribution of facilities within a given area. This paper attempted to map out and analyze the spatial d...

Following Nigeria’s Independence in October 1960 and recurring (early) droughts, especially in the north, governments at different levels were lured by the World Bank and other funding agencies to adopt mega-dam option for large- and medium-scales irrigation projects (i.e. covering land areas of between 10,000 and 62,000 ha; 24,710–153,200 acres)....

In recent years, the densely populated region around the burgeoning city of Kano in northern Nigeria has been the focus of much academic enquiry into the links between vegetation modification and fuelwood production and consumption. While many scholars have praised the socio-economic and ecological sustainability of Kano's rural–urban interface, ar...

In sub-Saharan Africa, urban and peri-urban food production has been identified as an important resource for meeting the challenges of rapidly growing cities, and the positive aspects of such production have been well documented in the literature. This paper examines some of the health and environmental concerns associated with urban and peri-urban...
