This book proposes operational approaches to public sector support to community-led development of urban low-income group social housing in the prevailing and medium-term. Within the context of mitigating and redressing the existential threats of climate change and global pathogenic transmission, building on current concerns of global heating and the lessons learnt from the 2020-22 COVID-19 pandemic, the book closely examines recent examples from a wide international range of countries and cities from the Sri Lanka experience to Arab States of the Middle East and the Andes. Topics include maintenance and management of public sector housing, poverty alleviation objectives, climate change mitigation, housing density, local land management and planning, land rights, affordable housing markets, and international governance and administration, ultimately pointing to the universal need for institutional, organisational and human skills development and the compilation and dissemination of operationally successful examples of participatory partnerships for affordable social housing. The book will be of interest to researchers, instructors, practitioners, and students of urban development, housing, environmental design, land-use planning, public administration and environmental health engineering.
