In this case study, undertaken in the Western Cape, a survey among 350 rural landowners revealed a typology of the significant amounts of often environmentally detrimental waste generated, and confirmed that inappropriate storage, collection and disposal strategies were employed on rural properties. Disposal sites were generally poorly located, constructed and operated, generating environmental problems. Owners' perceptions of their own practices, their attitude towards participation in alternative waste management schemes, and their service needs are reported on in this article in order to inform service provision strategies. Owners expressed a variety of needs and requirements for public service delivery, as well as a willingness to participate in and to pay for services.

As elsewhere in the world, an acute need exists to balance development and economic growth and conservation in the coastal zone as an exploitable resource frontier area. Vegetated buffers and greenways are conservation concepts that have been used with great success in such conservation efforts. They are applied in the study area through the use of a Geographic Information System (GIS) as spatial decision-support system to legitimize the demarcation of a vegetated buffer zone. The method of multicriteria evaluation, as applied here, incorporates public decision-making in constructing an objective model for buffer zone demarcation. Representatives from interested and affected parties participated in model construction and calibration, resulting in the spatial delimitation of a multifunctional vegetated buffer. It conforms to a range of functional criteria and can serve as an environmental element in coastal conservation planning frameworks.

Once identified, these factors can be used to ascribe priorities for rectification and effective management. Various formulas have been compiled for this purpose, but are specific to particular industries, having environmental risk factors that are unrelated to the
