Poor solid waste management has increasingly taken a hegemonic position in urban policy discourse in Ghana. Often, the discourse centers on free market principles and inflexible waste management laws that promote privatization and deregulation. Recently however, source separation is dominating discussions on policy alternatives. This study investigates determinants of households' source separation behaviour and solid waste disposal options among residents of Ghana's 'Millennium City'- Accra using logit and multinomial logit regression models respectively. The logit regression estimates show that households' source separation behaviour is determined by gender, income, monetary incentives, attitude, compound house dummy, type of service provider and other household location variables. The multinomial logit estimates reveal that gender, age, age square, income, household size, employment, housing type, and attitude predicted household disposal options. We argue that to win the 'garbage war', source separation should be promoted by the Accra Metropolitan Assembly as this may enhance positive attitudes towards proper waste management.
加纳的城市政策话语中,固体废物管理不善问题日益突出,成为主导议题。在这些讨论中,往往侧重于自由市场原则和僵化的废物管理法规,这些原则和法规推动了私有化和放松管制。然而,最近,源头分类在政策替代方案的讨论中占据主导地位。本研究采用逻辑回归和多项逻辑回归模型,分别调查了加纳“千禧城”——阿克拉居民家庭源头分类行为和固体废物处理选择的决定因素。逻辑回归估计结果表明,家庭的源头分类行为取决于性别、收入、货币激励、态度、复合房屋虚拟变量、服务提供商类型和其他家庭位置变量。多项逻辑回归估计结果表明,性别、年龄、年龄平方、收入、家庭规模、就业、住房类型和态度预测了家庭处理选择。我们认为,为了赢得“垃圾战争”,阿克拉大都市议会应推广源头分类,因为这可能会增强人们对妥善废物管理的积极态度。
