ISWA’s side event will deal with the global challenge of providing people universal access to professional and sustainable waste management services as an alternative to open waste dumpsites to achieve a healthy, resource-efficient, and climate-friendly development. The event will address how improper waste management (i.e. dumpsites) affects the environment and human health, what the costs of inaction are, and what actions cities should take in this regard. According to the Global Waste Management Outlook (GWMO) of UNEP and ISWA, around 2 billion people still do not have access to waste collection services and the waste of 3 billion people is not managed in an environmentally sound manner. Particularly in low- and middle-income countries, open dumping and burning close to urban centers represent a substantial threat to human health, climate and the marine environment. Open dumping and burning of waste is polluting the air, soils and waterways. ISWA’s “Wasted Health” report highlights the various negative impacts due to pollution by dumpsites. Uncollected municipal waste that ends up at illegal or improper dumpsites close to waterways and coasts generate marine litter, affecting marine ecosystems as well as the fishing and tourism sectors. According to the Ellen MacArthur Foundation, there will be more plastic than fish in the world’s oceans by the year 2050. Around 80 per cent of marine litter comes from land-based sources due to insufficient waste management practices. The side event will seek to identify the appropriate actions required following the conclusions and recommendations of GWMO and ISWA’s Roadmap to achieve the New Urban Agenda as well as the SDGs. The panelists involved possess substantial theoretical knowledge and practical experience on this matter and will share this with a focus on low- and middle-income countries.
