Nutritional Status, Dietary Intake and Dietary Diversity of Landfill Waste Pickers.

The purpose of this study was to investigate and describe the nutritional status, dietary intake and dietary diversity of waste pickers in South Africa, a socioeconomically vulnerable group who makes a significant contribution to planetary health through salvaging recyclable material from dumpsites. Participants were weighed and measured to calculate body mass index (BMI). Dietary intake was recorded using a standardised multipass 24 h recall. Individual dietary diversity scores were derived from the dietary recall data. Data were collected from nine purposefully selected landfill sites located in six rural towns and three cities in four of the nine provinces in South Africa, providing nutritional status information on 386 participants and dietary intake on 358 participants after data cleaning and coding. The mean BMI of the study sample was 23.22 kg/m2. Underweight was more prevalent among males (22.52%) whilst 56.1% of the females were overweight or obese. The average individual dietary diversity score was 2.46, with 50% scoring 2 or less. Dietary intake patterns were characterised as monotonous, starch-based and lacking vegetables and fruits. The nutritional status, dietary intake and dietary diversity of waste pickers reflect their precarious economic status, highlighting the need for health, social and economic policies to improve access and affordability of nutritious food.

A three-pronged approach to waste composition determination.

Understanding solid waste composition has frequently been cited as one of the most valuable resources to those responsible for the proper management of solid waste. The unique contribution of this article lies in the fact that a waste characterisation study, conducted in a remote rural town in South Africa, was combined with an illegal dumping contents mapping and a household survey. This enabled researchers to gain a more thorough understanding of household waste management practices and challenges in this community, bridging the knowledge gap that is created when illegal dumping and household perceptions are omitted from waste characterisation studies in study areas where illegal dumping is an ongoing concern. The study therefore contributes to understanding the waste behaviour of households within the larger context of the town's waste management practices. Results indicate that, in order for municipalities to fully understand how to manage their waste, the contents of illegal dumping, where present, and household surveys should also be included in waste characterisation assessments.

The dynamics of indiscriminate/ illegal dumping of waste in Fisantekraal, Cape Town, South Africa.

Indiscriminate dumping may be considered a 'wicked problem', as it is regarded as a complex, intractable, open-ended problem and it includes rights-based and justice issues. An understanding of the dynamics of indiscriminate dumping may assist with improving the management of indiscriminate dumping. The results show that indiscriminate dumping in Fisantekraal is a serious threat. From the first round of data collection to the last, no dumpsite disappeared despite the efforts of the community to clean up each month. Rather, the formation of new dumpsites and the extension of a few existing ones were evident. The morphology composition of the waste suggests that the main dumpers are the households and spaza shop owners. Conversations and collaboration between the authorities and community are encouraged in order to explore solutions to indiscriminate dumping.

Exploring the Potential Health Risks Faced by Waste Pickers on Landfills in South Africa: A Socio-Ecological Perspective.

Landfill and street waste pickers in South Africa are responsible for collecting substantial volumes of recyclable material, saving municipalities millions and contributing to a generally healthier and cleaner environment. Yet waste pickers continue to operate on the fringes of the economy and are exposed to many risks, particularly health risks which have a direct impact on the sustainability of their livelihoods. This article, using a mixed-methods approach, explores the health risks to which waste pickers working on nine different landfills in the country are exposed. The socio-ecological framework was used to analyse and present the results. A key finding was that waste picking, by its very nature, lends itself to innumerable health risks, but that these can be lessened through concerted and collaborative efforts on the part of landfill operators, local authorities and other stakeholders. Integrating the 'self-employed' waste pickers into the formal waste management system should be comprehensive in order to limit health risks. Waste pickers will never have a risk-free environment, but facilitative policies and supportive institutions can collaboratively help to mitigate these risks and create a more sustainable and dignified working environment towards sustaining their livelihoods.
