Issues (other countries): Solid-waste Pollution In Lusaka

Contributed by Henry Kyambalesa
ZAMBIA, Nov. 10 -
1. INTRODUCTION.--Solid waste, like air and water pollution, is a form of environmental pollution that is mainly a by-product of human activities. As such, it is an inescapable problem in every human society. It is, by and large, a culmination of discarded products or parts of products--including broken and non-reusable bottles, metal cans, plastic sacks and containers, newspapers, and automobile parts and bodies.

Lusaka city, like many other cities in modern Zambia, is currently experiencing serious problems at all stages of solid-waste management--that is, the collection, sorting, transportation, and disposal of garbage. The seriousness of this problem is summed up by the UN Integrated Regional Information Networks (IRIN) in an article dated May 20, 2004 entitled "Zambia: Failure to Manage Urban Waste" found at http://www.queensu.ca/ as follows:

"Heaped garbage, a choking smell and pools of stagnant water sum up the state of Soweto market, the largest open-air trading area in Zambia's capital ... [and] are a sign of how urban waste management has failed in what was once called the `garden city' but is now cynically referred to as `garbage city'".

2. A HEALTH HAZARD.--The accumulation of solid waste in the capital city can be attributed to many factors, including the following: (a) public attitudes that are alleged to be generally characterized by lack of concern for the quality of surroundings; (b) failure by local authorities to prioritize garbage collection and disposal; (c) lax enforcement of by-laws relating to littering and other forms of contamination in public surroundings; (d) rampant and uncontrolled street vending; and (e) lack of financial and material resources resulting from irregular support in the form of grants from the central government.

But regardless of the reasons for the unprecedented accumulation of solid wastes in Lusaka city--and in other urban and sub-urban centers of Zambia, as a matter of fact--it is perhaps important to underscore the fact that such wastes are a serious health hazard. For instance, piles of uncollected solid-wastes facilitate the formation of pools of stagnant water and create breeding grounds for mosquitoes and, as such, dispose residents to the deadly malaria parasite.

Besides, outbreaks of cholera, meningitis and other contagious diseases in the country have been directly linked to the absence of effective solid-waste disposal systems, together with the lack of potable water in some communities and unhygienic street-vending of foodstuff.

The congestion of people in the city's urban and sub-urban areas occasioned by rural-to-urban migration has perhaps exacerbated the potential for outbreaks of communicable diseases in such areas. Inevitably, the potential health risks have become more profound and mind-boggling given the city's lack of adequate resources to provide for decent social services, public amenities and improved sanitary conditions to unprecedented numbers of residents.

Members of the MANGOKA Secretariat--who represent the residents of Marapodi, N'gombe and Kamanga residential areas in matters of refuse collection and disposal, and public health and sanitation--would perhaps provide us with a more precise and down-to-earth account of the potential health hazards associated with high levels of solid wastes in the capital city, whose sources include households and both commercial and industrial undertakings.

3. POTENTIAL SOLUTIONS.--A viable and long-term solution to the problem of solid-waste pollution is regular collection and recycling of all forms of solid waste. For example, plastics, discarded metals, and paper wastes can be collected and recycled into usable raw materials. Another feasible solution to the problem of solid wastes is the production of biodegradable products--that is, any products that are made in such a way that they can be naturally broken down into elements that are less harmful to the physical environment upon being disposed of.

Moreover, making reusable products and parts of products can greatly contribute to the mitigation of solid wastes. For example, containers can be designed in such a way that they can be used for other purposes once their original contents are exhausted. Junk yards are certainly not a viable solution to the problem of solid-waste pollution because they, among other reasons, take up areas that need to be reserved for commercial, residential, recreational, and/or other worthwhile purposes.

Besides, it is essential for the Zambian government to require locally based organizations to include environmental impact statements in their business plans or corporate charters. Suggestively, such statements need to incorporate the following, among other things: (a) identification of potential impacts of their operations on the environment; and (b) a description of measures they are geared to take in managing these impacts to tolerable levels.

It is also important for the government to provide adequately for the material and financial needs of the Environmental Council of Zambia, which was created under the Environmental Protection and Pollution Control Act of 1990 to protect the environment and control pollution so as to provide for the health and welfare of persons, and the environment as follows: coordination of environmental management; promotion of awareness about the need to protect the fragile natural environment; and enforcement of regulations pertaining to the control and prevention of air, water and solid-waste pollution.

Further, inclusion of subjects or courses of study aimed at sensitizing citizens to environmental issues and problems in the curricula of all educational and vocational training institutions can lead to conduct among citizens that is environmentally benign. To be effective, such education needs to be interdisciplinary in nature; in other words, it needs to be aimed at preparing citizens to be: (a) knowledgeable about the interrelatedness of biophysical and socio-cultural environments of which humans are a constituent part; (b) aware of environmental issues and problems and of viable alternatives in resolving the issues and problems; and (c) motivated to work voluntarily toward the protection and improvement of the fragile natural environment.
