Urban livelihoods are a complex interplay of economic, social, and environmental factors, shaped by rapid urbanization, demographic shifts, technological advancements, and socio-political dynamics. In modern cities, particularly in the context of sustainable development and the vision of smart cities, addressing urban livelihood concerns requires a multi-dimensional understanding of how people earn a living, access resources, and participate in urban economies. Urban livelihood concerns are not uniform; they differ across socio-economic groups, geographical areas within a city, and sectors of employment. Common concerns include unemployment, underemployment, job insecurity, income inequality, informal sector dependence, lack of skill development, limited access to affordable housing, inadequate health and social services, and environmental vulnerabilities such as pollution and climate-induced hazards. These challenges are further intensified by migration from rural areas, creating pressures on urban infrastructure, social cohesion, and resource management. Additionally, marginalized populations, including women, youth, elderly, and differently-abled individuals, often face systemic barriers in accessing decent livelihood opportunities, exacerbating social exclusion and economic disparity. The informal sector, which constitutes a significant portion of urban employment in many developing countries, poses both opportunities and challenges. While it provides livelihood options to a large segment of the population, it often lacks legal protection, social security, and stability, making urban workers vulnerable to exploitation and economic shocks. Addressing these urban livelihood concerns requires a comprehensive framework that integrates economic development, social equity, environmental sustainability, and technological innovation. The sustainable livelihoods framework is particularly useful for analyzing and designing strategies to enhance urban livelihoods. This framework identifies five core types of capital essential for livelihoods: human, social, natural, physical, and financial. Human
