Comparative analysis of the street generation of inorganic urban solid waste (IUSW) in two neighborhoods of Mexico City

The role of solid waste management as a response to urban flood risk in developing countries, a case study analysis

“…Residents in Tanzania also recognise that poor solid waste management blocking streams has exacerbated their flood risk [17]. The type and quantity of waste differs significantly between countries and within urban areas [5]. Industrialized countries and urban areas will tend to generate greater quantities of waste compared to developing countries and rural areas.…”

“…The management of waste is a perennial problem in developed and developing countries [1,2,3] and it is an increasingly serious issue in respect of flood risk management [4] for the following main reasons: The poor disposal of waste frequently leads to blockages in drainage and watercourses [5,6], this effectively reduces their conveyance and leads to flooding [7,8], storage areas can also be blocked by waste; During a flood this waste and other debris collected by floodwaters can cause increased damage to property and lead to higher flood losses [9,10]; after a flood the deposition of waste can block access and be a source of toxins and breeding ground for disease. Floods can also have an impact on waste management systems [11] leading to leaching of toxins into groundwater.…”

An Approach to Litter Generation and Littering Practices in a Mexico City Neighborhood

“…A comparative study of litter generation conducted in 2006 in two neighborhoods of Mexico City with different socioeconomic profiles [29] showed that the higher-profile neighborhood was representative for carrying out a perception study, due to its high levels of litter generation. This higher-profile neighborhood was Jardín Balbuena.…”

“…Six sites were selected for sampling based on a study by Barriada-Pereira [34], the official Mexican norm NMX-AA-061-1985 [35], and the study by Muñoz-Cadena [29] performed in 2006 in the same sites, with a total length of 2,400 m. This resulted in a pre-sample size of 115 households by socioeconomic level with a risk factor of α = 0.05 from a total of 500 households. The number of households in each of the sampled blocks was 250, which is in compliance with the requirement of 115 households provided in the official Mexican norm.…”

“…If these results are compared with actual data, a significant relationship is found for all days of the week except Fridays. A possible explanation for this may be the fact that people consider Friday evening a part of the weekend, and are prone to believe that during these rest days people stay at home or close to home, with a potential consequent increase of RMSW generation in nearby public spaces [29], which remains untouched by cleaning services through Monday morning. Nevertheless, present results in this regard differ from those obtained in the same neighborhood in 2006, when the period showing a significant difference in RMSWS generation was Friday through Sunday [29].…”
