an obvious environmental problem in cities all over the world is the solid waste produced by industry and consumption. In rapidly expanding metropolitan areas, this accumulation is more of a catastrophe problem than ever before. Municipal solid waste is a significant environmental issue in Bauchi. Government laments that the current disposal sites are quickly filling up following the privatization of services with various businesses known as private sector participants (PSPs) that run as Bauchi State Environmental Protection Agency (BASEPA) franchisees. In order to increase the amount of trash that is diverted from landfills as a result of the rapidly filling dumpsites, BASEPA plans to implement a solid waste source separation policy in the city. Examining the feasibility of implementing a source-separation policy in the less compliant low-income population segment by assessing the aspects of attitude and perception is intended to give insight into the practical feasibility of instituting source-separation in all population segments. The data for this study were collected using a structured questionnaire. All analyses were conducted using the statistical package for social sciences (SPSS v25). According to the study, more than half (50.9%) of surveyed households have a poor perception of source separation, while 49.1% had a good perception of source separation. Similarly, it was also found that over half (52.5%) of surveyed households have a poor attitude toward source separation, while 47.5% of them have a good attitude toward source separation. It is recommended that a bottom-to-top approach of sensitization, orientation, and community engagement be adopted to improve the dimensions of perception and attitudes towards solid waste source separation in the metropolis.

Climate change vulnerability is the function of exposure, sensitivity, and adaptive capacity of its natural and socioeconomic systems. Following spatial “scale” of the assessment, administrative-territorial units were selected for this study. A field survey questionnaire was used to collect data for the study based on the sample size of 500 questionnaires that was administered to household heads in the study area. In the questionnaire, questions were designed to give respondents the opportunity to choose from several alternatives given in the instrument while descriptive statistics was for the analysis of data. Descriptive statistics analysis based on mean ranking was carried out to identify the level of peoples’ vulnerability to climate change in the study area. The exposure assessment was based on the response analysis of baseline information. The sensitivity assessment for the study was analyzed by using physiographical and socioeconomic characteristics, described by a set of specific indicators and responses of the residents. The adaptive capacity was captured by general economic and agricultural indicators, taking into consideration the major occupation the predominant lifestyle of the residents. Through a ranking approach, the relative vulnerability of each ATU was calculated by summing its sensitivity and adaptive capacity ranks; the latter were obtained as combinations of their primary indicator ranks, arranged in an increasing and decreasing order, respectively. The major climate change exposure pathway in the study area were reduction in green environment, decrease in total annual rainfall, warmer weather, early cessation of rainfall, late on-set of rainfall and shrinkage of water bodies. The major sensitivity to climate change was decrease in crop yield, whereas increase in cost of food crops, drought incidents, famine, poverty, indiscriminate falling down of trees and disaster. It was also established that the major adaptive strategies to climate change in the study area were irrigation farming, use of organic manure, planting of drought tolerant varieties and early planting.

Electronic waste generation has been increasing at a rate three times faster than that of general waste stream. Developing nations like Nigeria bear the consequences as it is estimated that 500 containers, each carrying about 500,000 used computers and other electronic equipment, enter Nigeria’s ports every month from the United States, Europe and Asia. To this effect, The United Nations Environmental Programme (UNEP) and the Federal Government of Nigeria have announced a $15 million initiative to establish an electronic system in Nigeria, which will pioneer safe e-waste recycling in the country. It is against this background that this study was conducted to determine the households’ awareness and practice towards the recycling of e-waste, as well as the most suitable collection pattern within Kano Metropolis. The data for this study was collected using Open Data Kit (ODK) mobile phone platform, which contained questions on households’ characteristics, current practices regarding disposal and recycling of electronic waste as well as their awareness dimension on the recycling of e-waste. Statistical Package for Social Sciences (SPSS) was used to estimate the average number of unused households’ appliances and also to analyse household awareness and practice. The awareness dimension of the surveyed households about recycling of electronic waste was determined and 97% of the households are aware of the significance of electronic waste recycling. The positive statements presented about awareness indicates a positive awareness dimension about the significance of recycling electronic waste. Among the sampled households, 23% engage in e-waste recycling, and they all do this by selling their wastes (electronic waste, inclusive) to house-to-house scavengers. Majority of the households (77.4%) do not recycle electronic waste. They either keep them at home for decoration, give them out for free, burn them or dispose them in open dumpsites. The average quantity of e-waste prese

River Basin Development Authorities (RBDAs) in Nigeria were established since 1976 and they operate mechanized and capital intensive programmes. All the 12 RBDAs operate as separate Authorities, each with separate administrative and operational autonomy, but sharing the Basin Resources of the 8 Hydrological Areas. However, their performance was generally described as disappointing. This study first reviewed the existing organization of the 12 RBDAs in Nigeria. Thereafter, one of the 8 Hydrological Areas – the Komadugu-Yobe Basin (KYB) – which is the major inland drainage system in Nigeria was purposely selected for detailed study. Information on its major streams, tributaries and the main river; the hydrological area as well as the RBDAs sharing resources of the basin area, was gathered using ArcGIS version 10.0 and Erdas Imagine 9.2 software, as well as topographical and hydrological maps. This was processed and analyzed based on the principles of Stream Ordering and Logical Framework Analysis. The findings revealed that in establishing the RBDAs, basin-wide consideration of their sphere of operation was not taken into account. Dams were constructed before establishing the RBDAs. Runoff waters and spill ways were poorly controlled leading to flooding during rainy season and reduced water supply downstream during dry season, with serious environmental and socio-economic problems in the basin area. It was concluded that the RBDAs in Nigeria were poorly organized and have consequently failed to accelerate agricultural and rural development, and have also failed to boost food and industrial crop production as expected. The need was established for effective organization of River Basin Development and Management to improve their performance. To achieve this, a Conceptual framework for Integrated River Basin Development and Management was developed for adoption by river basin managers and other relevant stakeholders in Nigeria and around the globe to improve performance.

This study investigated the factors influencing municipal solid waste generation (MSWG) in Bauchi town, the administrative headquarters of Bauchi state, Nigeria. The study used quantitative method, while experiments and questionnaire surveys, were used as the major instruments for data collection. Data on solid waste generation and the socioeconomic attributes of residents from 400 households were collected from residential zones within Bauchi town, the study area. Descriptive statistics, Correlations and Standard Multiple Regressions (SMR) were computed for data analysis using SPSS 2.2 software. Twelve (12) socioeconomic factors were computed in SMR to determine the significant factors of MSWG in the study. The results showed that five factors, namely: household size, income, education, house head age and occupation have exerted significant influence on MSWG in the study area. The results also showed that F (5:362) = 84.058 at p ≤ 0.01 and adjusted R2 = 0.531; which indicated that the factors in the SMR model have sufficiently explained the variance in MSWG in Bauchi town. The study concluded that the five significant predictor factors have adequately explained the variance of MSWG in the study area. Therefore, the factors have implications for planning of effective waste management system in Bauchi town, Nigeria. © 2017 American Scientific Publishers. All rights reserved.
