Livelihood is a broad concept that refers to the means, activities, and resources through which individuals or households secure the necessities of life such as food, clothing, shelter, health, and education. It is not only limited to employment or income but encompasses the entire range of capabilities, assets, and activities required for a sustainable existence. A livelihood is considered sustainable when it can cope with and recover from shocks and stresses while maintaining or enhancing its assets and capabilities without undermining the natural resource base.

For instance, in rural settings, livelihood profiles may include agricultural practices, livestock rearing, small-scale enterprises, and reliance on natural resources. In urban areas and smart cities, livelihood profiles often involve employment in services, manufacturing, information technology, construction, transport, and informal sector activities.
