Prioritization and Analysis of Watershed: A Study Applied to Municipal Solid Waste

This paper shows a watershed prioritization analysis applied to municipal solid waste. The study area was the macrowatershed “Cañón del Sumidero”, in the state of Chiapas, Mexico. Geographic information systems, multi-criteria evaluation techniques, as well as several geomorphometric, land use, vegetation and waste management variables were used. The results indicate that, of the set of watersheds analyzed (4 subwatersheds and 80 microwatersheds), only 14 (2 subwatersheds and 12 microwatersheds) have high priority, since they are severely affected by the mismanagement of solid waste. This is also due to the major presence of urban settlements, which are places with different dynamics in terms of population growth, migration, as well as access to infrastructure and services, such as collection and final disposal of waste. Additionally, the incidence of certain biophysical and geomorphometric variables, such as steep slopes, high rainfall and high drainage density, among others, exacerbate the waste-related problems. The remaining watersheds (2 subwatersheds and 68 microwatersheds) showed moderate or low prioritization values because of the low amount of solid waste produced there. Finally, this work concludes that the regionalization of municipalities and the management of solid waste through decentralized operating agencies can help solve solid waste management problems since this approach would permit to delegate non-primary activities from watershed operating agencies to other specialized waste agencies.

The City

The rapid increase in urban population has resulted in poor environmental conditions in urban and peri-urban settlements. In most developing countries, the problem of inefficient municipal solid waste management (MSWM) is endemic. The problem manifests in heaps of uncollected solid waste or ubiquitous illegal dumps on open areas and by the street sides. This paper examines issues of solid waste management practices in the City of Kwekwe in Zimbabwe. It highlights types of waste, its generation, transfer and disposal. A mixed methodological approach including field observations, structured questionnaire survey and face-to-face interviews were employed in the gathering of data for the study. The key findings established to be the factors affecting effective solid waste management in the City are irregular solid waste collection, inadequate operational funding, inappropriate technologies, inadequate staffing, lack of knowledge cooperation and knowledge on the part of the residents. Based on the research findings, principles of environmental stewardship need to be promoted in the City.

Urban Settlements

The rapid increase in urban population due to the influx of the citizenry in search for better conditions of life has resulted in poor environmental conditions in most urban and peri-urban settlements in the country. Municipal solid waste management (MSW) for that matter has become problematic within Sekondi-Takoradi Metropolis as the city is being inundated with so much filth which has proven to be very difficult and seemingly impossible for the municipal authorities to tackle. This study investigates the nature of solid waste problem in Sekondi-Takoradi Metropolis. A mixed methodological approach including field investigation, questionnaire survey, and structured and face-to-face interviews were employed in the gathering of data for the study. The key findings established to be the factors affecting effective solid waste management in the metropolis are irregular solid waste collection, inadequate operational funding, inappropriate technologies, inadequate staffing, inadequate skip, and lack of cooperation on the part of the citizenry.
