Soil disinfestation: environmental problems and solutions

Cities in eastern Africa have been growing at an unheralded pace, and will continue to do so for the foreseeable future. Despite this rapid urbanization, very little research has been focused on energy and the environment in urban eastern Africa. This paper contains a review of what little work has been carried out to date. Several conclusions are pointed out. First, cities throughout the region remain small and have formed largely without industrial development. ‘Urbanization without industrialization’ means that the existing urban environmental problems are attributable to inadequate provision of service and not to the industrialization-linked problems found in more developed countries. Even if economic growth improves, action will be necessary to alleviate existing environmental problems. Second, the expected rapid pace of urban growth will impose tremendous costs at all levels. Increased user costs, either through reliance on private-sector alternatives or through public-sector tariffs, must be increasingly relied upon to defray the fiscal impacts of rapid urbanization and to assure the sustainability of urban infrastructural systems. Third, as the anticipated urban growth and industrialization take place, the focus of energy and environmental planners working on cities in eastern Africa will shift from basic service provision to increasingly complex problems. These shifts will require labor and financial resources far exceeding those currently found in these countries. Fourth, although energy and environmental needs may differ according to the size of the city, there has been little or no attention paid to problems outside of the primate cities. As a result, it is unclear how the problems and solutions will differ across the urban hierarchy. Clearly, urban planners need to consider the importance of energy and the environment. At the same time, energy and environmental researchers must pay greater attention to urban areas.

Problems And Solutions

The aim of this study is to determine the views of candidate science teachers about environmental problems and solutions to these problems. One of the qualitative research designs, phenomenology, was used in the research. Data were collected with a semi-structured interview form developed by the researcher. In the analysis of the research, a descriptive analysis technique was used. The study was carried out with 19 science teacher candidates. When definitions of the environment are examined, it is as “the environment in which living and non-living beings interact, the area where living things live, the artificial environment-natural environment.” Candidate teachers identified air pollution as the most important environmental problem. They stated that environmental problems occur due to production, consumption, both production and consumption and natural reasons. Candidate teachers discussed solution proposals of environmental problems individually, professionally, socially, and administratively. In individual solution proposals, it is recommended to use public transport, to encourage afforestation, to consume resources economically, to reduce the use of perfume-deodorants and fossil fuels, and to raise awareness with experiments, activities, visual and practical solutions under professional solution suggestions. When social solution suggestions are examined, it is stated that to raise awareness; it is necessary to produce visual and artistic activities, meetings, training, and projects, to be engaged in conscious agriculture in managerial solution offers, to use renewable energy sources, to recycle, to build industrial establishments outside of residential areas, to establish treatment facilities, and to install and inspect filters in factory chimneys.
