This chapter advances UN SDG goals 11, 13, and 7 by discussing the Smart City potential for contributing to the reduction of external dependence on fossil fuels and the promotion of renewable energy sources and the mitigation of environmental impacts and effects of climate change.

The goal of global food security will be achieved only by improving the qualitative and quantitative traits of crops through exploitation of metabolic pathways involving advanced analytical tools and technologies.

This chapter provides a comprehensive strategy to assess ecological systems’ involvement in indigenous wellbeing, signifying how natural systems are intertwined with people’s communal, economic, and cultural environments, along with their skills.

Understanding livelihood vulnerability to hydrometeorological hazards is a crucial challenge for policymakers to create a clear foundation for vulnerable coastal residents. Using microlevel livelihood vulnerability research employing LVI and Socioeconomic Vulnerability Index, this chapter measures the magnitude of indigenous peoples' vulnerability to the detrimental consequences of hydrometeorological hazards on socioeconomic conditions.

The indigenous peoples make a lasting impact on the society and people through their activities such as protection of the ecosystem, agriculture, and the maintenance of ethnic origin; these people are faced with many risks regarding health, sanitation, water, climate change, and pandemic. The chapter aims to determine the integration of the indigenous population into society and the functions of social work in this regard.
