**1. Introduction**

Informality has been growing in cities; not only of the Global South, but even in the Global North [1]. As a result, informality has become a permanent feature of urban development. Urban informality has actually developed to be the form of urbanisation in many cities [2]. This, therefore, calls for the integration of the informal sector into the main stream development of cities. This inclusion will lead to inclusive and sustainable cities. Slum settlements are lacking a lot of services and this is against the sustainable development goals, which seek to reduce the number of people living in slums by 2030. Informal settlements have grown in magnitude in cities of the global South but services such as sanitation

and waste management are severely lacking thereby exposing them to life threatening environments. People in informal settlements are living in epicentres of diseases outbreaks and this weighs heavily against city sustainability [3]. Informal settlements are playing a critical role in the provision of housing to the low income urban dwellers and this provides urban resilience and sustainability. So city authorities should take it upon themselves to provide services to these otherwise neglected spatialities for sustainable housing. Excluding informal settlements in the delivery of services creates spatial deprivations, which does not auger well with sustainable housing. Sustainable housing aims to improve the quality of housing through slum upgrading and provision of services that will lead to safe and liveable spaces in informal settlements, [4]. Waste management is one of the important services that should be offered by the city authorities and it should be enjoyed by every resident as a way of giving them their right to the city. This chapter examines waste management in the informal settlements and its impact on the hygiene of spaces occupied by the informal settlements and the city at large. It analyses waste management practices in the informal sector and evaluates its implications on people's right to the city and sustainability of housing in the informal settlements. Waste management in the informal sector has different ramification on the city's general hygienic conditions and also reflects the inclusivity of the city in terms of how the services are spread to the diversity of urban inhabitants. This research is important in the sense that it contribute to the growing literature on the sustainable housing in cities. It examines sustainable housing from the informal settlements.
