Effects of Solid Waste on Urban Warming in Warri Metropolis, Nigeria

Abstract

This study examined the effects of solid waste on urban warming in Warri metropolis. To achieve this, the study generated data from field measurements of volume of waste generated and greenhouse gases. The data were collected from five (5) major waste dump sites in Warri metropolis. The data generated were analysed using bivariate correlation and multiple regression. Results obtained revealed that 25.1% of waste generated in Warri metropolis was found in the commercial areas of the metropolis while 4.3% of the waste generated was recorded in the low density Areas, 19.7% of the waste generated was found in the high density area (Okumagba, Ugborikoko, Enerhen village, Airport road and upper/lower Eredjuwa) and the remaining 51.9% was generated in the industrial, traditional and fringe zones of Warri metropolis. Warri metropolis has an urban bias of 4.16˚C. There is a significant relationship between temperature and volume of waste generated at R value of 0.722. The temperature in Warri metropolis is significantly dependent on greenhouse gases emitted at P < 0.05. It is therefore, recommended that programmes to sensitize and sustain the waste management concepts among communities through media be established.

Weather Variability in the Vicinity of Waste Dump-Sites in Benin City

“…ISSN 2164-7682 2018 However, the high concentration of GHGs at dumpsites is attributed to fermentation of wastes materials, decomposition of organic material within the waste constituents, and waste incineration at dumpsites. This finding disagrees with the findings of Efe et al,(2013);Yusuf &Oyewunmi, (2008) & O"Neil et al (2001, who attributed volume of GHGs at waste dumps to anthropogenic activities, population growth and industrial processes. Nevertheless, the emitted gases have effect on temperature variability in the area.…”

“…In some cases attempt is made to create designated waste dumps, however, due to poor dump site management, these waste dumps rapidly become a menace to the environment where it is located. Some of the implication of poorly managed waste dumps include, health (Ozabor & Obisesan, 2016;Wokekoro & Inyang, 2007), city"s aesthetic depreciation (Atuegbu, 2007;Agbola & Jinadu, 2006), GHGs emission (Efe et al, 2013).…”

“…Some studies have inquired about the health effects of waste dumps (Ozabor & Obaro, 2016;Yusuf & Oyewunmi, 2008) others have looked at the environmental dangers of poor waste management (Bogner, Ahmed, Diaz., Faaij, Gas, Hashimoto, Mareckova, Pipatti., & Zhang, 2007;Sá nchez-Rodrí guez, Seto, Simon, Solecki, Kraas & Laumann, 2005); while Efe et al, 2013, looked at the GHGs pollution associated with poor waste management in urban centres. This study is spurred to look at the effects of poor waste management on weather (Temperature) variability in the vicinity of waste dump sites in Benin City.…”

Air temperature, relative humidity, climate regionalization and thermal comfort of Nigeria

“…Southwestern Nigeria has rapidly urbanized since colonial times (United Nations, , ). Commerce and industry have grown and with them administration and the human population, and these have had their impacts on local climate with ‘heat islands’ in many of the towns (Omogbai, , Aina, , Oniarah, , Adebayo, , Efe, , Adelekan, , Akinbode et al , ).…”

Urbanization and Major Ion Hydrogeochemistry of the Shallow Aquifer at the Effurun - Warri Metropolis, Nigeria

“…Data for the leachate and borehole water obtained from Akudo et al (2010) Dumpsite and landfill leachate and sewage are indeed known sources of chloride, bicarbonate, calcium and magnesium loading to native groundwater (Panno et al, 2006;Uma, 2004;Hanchar 1991;Bradley et al, 1987, Baedecker & Back, 1979. Thus Akudo et al (2010) report dumpsite leachate concentrations of up to 932mg/l, 2,208mg/l, 170mg/l and 396 mg/l for Na, HCO 3, SO 4 and Cl respectively from dumpsites in Warri, while Efe, Cheke and Ojoh (2013) show that up to twenty five huge and open garbage dumpsites and landfills are randomly located in the metropolis, Figure 2. This is in addition to the potentially tremendous amount of sewage generated by close to a million persons from numerous home and industrial onsite septic tank sewage treatment systems.…”
