Cities worldwide grow rapidly, as does the amount of waste that they generate. This is particularly problematic in low-income countries. Their large cities often have limited resources to provide the essentials, such as a functioning garbage collection system. Urban management is often overwhelmed by the mass of trash the city generates and no political actions are taken. Even worse – policy makers often refuse to supply any services in the slums. These areas in particular drown in their own garbage. This inevitably leads to health problems in the communities, destroys the environment and brings lots of extra costs for the entire city, because of air, water and soil pollution.
These threats remain constant, as long as unmanaged urbanisation continues to intensify. Therefore a city must secure sufficient management of all its areas and for different types of waste: municipal solid waste, wastewater, and sludge from human excreta to ensure sustainable development.
providing a proper waste management falls under these SDGs:
The 2030 Agenda for Sustainable Development is a plan of action for people, planet and prosperity. All countries and stakeholders, acting in collaborative partnership, are starting to implement this plan. The 17 Sustainable Development Goals (SDGs) and 169 targets demonstrate the scale and ambition of this Agenda, which balance the three dimensions of sustainable development: economic, social and environmental.
