Ports have played an important role in the history of Indian trade as they had always been the poles of international trade and commerce since colonial times. They had also acted as a catalyst for the economic development of the nations from historic times till now. Despite the tremendous growth of various other major modes of transport systems such as railways, roadways in case of land routes for internal trade and airways for external trade, ports still continue to coexist with them mainly in sea-borne exchange of goods both in internal as well as in external trade of India. This chapter studies the impact of globalization on economic development of India through the maritime trade growth at Major ports, being the sustainable transport mode, during the period (1980–2020). Using econometric and statistical tools it observes that Major ports have played a significant role in growth of sustainable transport and trade development within India, since the colonial times till date. Not only that, positive impact of globalization, (in terms of growth of trade globalization index) also have resulted both in increased volume of total and overseas trade performance in overall growth of international trade at Major ports of India, thus, reflecting higher economic development.

In this Chapter, cerium (III) oxide nanoparticles were prepared by co-precipitation method using hydrogen peroxide as the precipitant in slightly alkaline medium which is greener and environmentally suitable, cheap and best as compared to other conventional methods. Here, hydrogen peroxide acts as precipitating, reducing and stabilizing agents. Since studies worldwide reveal a very strong, significant positive association between air pollution and COVID-19 cases, hence, this environment-friendly synthesis process will prove to be most economically effective one to combat the COVID situation. The synthesized cerium (III) oxide nanoparticles were initially noted through visual color change from colorless pale yellow cerium (III) to light yellow cerium (IV). Moreover, the formation and size of cerium (III) oxide nanoparticles were evidenced by the X-ray diffraction, transmission electron microscopy and UV-VIS spectroscopy studies. The very high surface area and very small average crystallite sizes of these prepared cerium (III) oxide nanoparticles (5–20) nm in size is mainly responsible for their catalytic properties and hence can be effectively used for the removal of hazardous toxic pollutant gases such as carbon dioxide and sulfur dioxide from the environment with a view to combat the pollution within the environment to increase sustainability and also ensure a better, healthy and safe environment, particularly, in context of COVID in globalized world. This chapter, as its main objective, mainly focuses on utility of the nanotechnology and its beneficiary in creating a sustainable environment in economic world, particularly for gender development. Since the gas sensors will detect and reduce gaseous toxic pollutants from the environment, so lower the pollution greater will be sustainable environment development in terms of human development index and hence higher will be overall economic development in favor of Gender Development Index across world. However, as major findings, developing countries have been successful in maintaining a sustainable human development, in spite of higher Per Capita Income (PCI) growth, as compared to the role of least developing countries, with lower PCI in this global world, in favor of their respective gender development.

The chapter focuses on the roles of different socio-economic indicators in explaining the convergence or inclusiveness of income across different income groups in the world. Econometric, statistical and mathematical tools have been used as methodology. As major results, overall greater role of socioeconomic factors of social sustainability (SS) than economic sustainability (ES), have been found. This have caused greater income inequality among these various income groups of the world, with income diverging among various groups of countries, mainly, within Principal Country Groups II, together with slight sign of income convergence among the rest Principal Country Groups I and III respectively. However, greater predominance of inclusiveness aspect of socio-economic factors of ES, is also found among the Groups I and III respectively, together with their significant roles in raising CHI. This may have led to the possibility of slight income convergence within these groups.

Nanotechnology is nowadays very much successful in producing specifically functionalized nano-sized particles. In this work, copper nanoparticles were prepared by reduction method which is greener and environmentally suitable, cheap and best as compared to other conventional methods, particularly in the context of COVID in globalized world. The formation and size of copper nanoparticles was evidenced by the X-ray diffraction and transmission electron microscopy. The very high surface area of 35–50 m²/gm and very small crystallite sizes of 5–15 nm of these metal nanoparticles is mainly responsible for their effective involvement in removal of carbon dioxide gas as one of major hazardous pollutants from the environment. This chapter, as its main objective, mainly focuses on utility of nano technology and its beneficiary in creating a sustainable environment in economic world. Apart from laboratory experimental procedure and characterizations for preparation of copper nanoparticles, appropriate research methods such as simple statistical, econometric tools and mathematical tools have been used for economic analysis. However, as major findings of the results, developed countries have been successful in maintaining a sustainable human development, in spite of having higher per capita income (PCI) growth as compared to the role of developing countries with lower PCI in this global world.
