The study examined the influence of socioeconomic attributes of residents on domestic solid waste disposal methods in Lagos metropolis, Nigeria. Primary data for the study were obtained through questionnaire administered on residents in Eti-Osa, Ikeja, and Mushin Local Government Areas (LGAs) representing the low, medium, and high densities, respectively, into which the sixteen LGAs in Lagos metropolis were stratified. One out of every four wards in each LGA was selected for survey. From a total of 15,275 residential buildings in the ten wards, one out of every forty buildings (2.5%) was selected using systematic random sampling where a household head was sampled. Information obtained includes the residential characteristics and the disposal methods. Enquiries into the socioeconomic attributes of the residents showed that 59.9% were high income earners and 76.6% had attained tertiary school education. This study concluded that six disposal methods were common in the study area. Furthermore, through multinomial logistic regression, the influence of socioeconomic characteristics of residents (density, income, age of respondents, educational status, and length of stay) on domestic solid waste disposal methods varied significantly in Lagos metropolis. The study established that most of the solid waste disposal methods utilized by residents in Lagos metropolis were not environment-friendly.

Purpose. Analysis of the current state with municipal solid waste disposal based on official statistical information, development of a set of indicators based on the characteristics of regional waste disposal. Methods. Statistical information analysis methods, including method of multivariate statistical analysis - cluster analysis. Results. The development of a set of waste disposal indicators at the national level is based on official statistical information on solid waste generation and disposal, as well as waste disposal services. The analysis of the developed database by regions of Ukraine revealed some deficiencies in the primary information and consi- derable variability of the data. The transition from absolute to specific values is the basis for a set of indicators formation combined into three blocks, which characterizing the generation and disposal of municipal solid waste (5 indicators), waste disposal sites (12 indicators) and socio-economic indicators (3 indicators). For the territory of Ukraine zoning by the situation with the municipal solid waste disposal the cluster analysis method were used. Indicators calculated for 24 regions of Ukraine indicate significant data variability. On the basis of 11 indicators, the zoning of the territory of Ukraine was conducted according to the situation with the municipal solid waste disposal with the definition of four clusters (drawing on the map-scheme of Ukraine) and their generalized characteristics. Conclusions. In order to solve the problem of inter-regional comparison and qualitative analysis of information, it is advisable to move from the primary data on generation and disposal, as well as the provision of municipal solid waste removal services to derived means – indicators. As a result, four clusters of Ukraine regions with generalized characteristics for each group were obtained. According to the results of clustering, we can conclude that the worst situation is in Kyiv and Lviv regions. The best situation of municipal solid waste disposal (by a set of indicators) is in Volyn, Dnipropetrovsk, Kirovohrad, Odesa and Chernihiv regions.

The research instrument was an interview that was based on structured questions framed to extract primary data from the population.The qualitative method was adopted in analysing the data. Among other findings, the study unravelled that the practice of advocacy journalism among news editors on soot and indiscriminate dumping of solid waste is weak in Port Harcourt. More so, the study ascertained that none of the news editors adopted news commentary as an approach in the advocacy on soot and indiscriminate disposal of solid waste in Port Harcourt. Given the findings, it is recommended that news reports on soot and indiscriminate disposal of solid waste in Port Harcourt should be done regularly to strengthen the advocacy and contribute to change of attitudes of the masses toward the environment. It is also recommended, among others that news commentary should be adopted by news editors in Port Harcourt as part of the strategies to advance advocacy on soot menace and indiscriminate disposal of solid waste in that city, due to the educative, expository and detailed nature of the commentary.
