Many stakeholders have been more interested in the previous few decades due to the diaspora’s involvement in topics typically related to development, such as trade, poverty reduction, economic growth, and post-crisis recovery. People are increasingly acknowledged for participating in transnational activities and their sympathies and connections to their countries of origin and destination. Governments are looking for ways to work more closely with diaspora populations to help them fulfil their goals and reach their full potential. This potential encompasses a wide range of resources that can be mobilised through international networks, not just financial remittances. The term “diaspora” has no universally agreed definition, and it refers to a vast range of phenomena. The chapter’s main objective is to demonstrate how each element contributes to development and the possible theoretical and practical effects on society. The author shows the benefits of transnationalism, diaspora, and intercultural communication within societies. These benefits include the sharing of knowledge, ideas, and values that positively impact the lives of the diaspora community’s counterparts in the country of origin and empowerment of the local countries through financial and non-financial diaspora remittances. As a result, this chapter helps readers understand how different forms of development contribute to improving civilisation in modern times.
