This study formulates conditions for sustainable impacts of inclusive and responsive governance through ‘invited spaces’ offered by the government and ‘claimed spaces’ created by the poor. The study questions how increased contributions to poverty reduction and improvement of quality of life for Nairobi citizens can be realised in an equitable and responsible way, while contributing to development of the city and country. To adequately address this two-sided objective of economic growth and poverty reduction in the contemporary context, the study analyses both processes and impacts; moreover it examines impacts in terms of quality of life as well as influence and political rights. The study explores the individually claimed spaces of households in Nairobi’s slums, the collectively claimed spaces of hybrid mechanisms for access to peri-urban land and tenure, and the invited spaces of city-wide governance networks.
