1. Introduction

In an era where globalization and migration continue to shape societies, the significance of maintaining connections with one’s homeland has never been more crucial. Diaspora communities, spread across the globe, seek innovative ways to preserve their cultural heritage, contribute to their countries of origin economically, and maintain the fabric of their social identity. Information and Communication Technologies (ICT) have emerged as vital tools in bridging the physical distances that separate these communities from their homelands. This paper aims to explore the multifaceted role of ICT in enhancing diaspora engagement through social media platforms, mobile applications, online forums, and virtual cultural events, alongside their economic contributions via remittances, crowdfunding, and entrepreneurship. The advent of social media has revolutionized the way diaspora communities communicate, offering platforms for more frequent and substantive exchanges about cultural, economic, and political issues. Mobile applications have similarly transformed the remittance landscape, enabling faster and cheaper transactions, which bolster the economies of recipient countries and strengthen diasporic ties. Online forums and platforms offer spaces for debate, information sharing, and collective mobilization, playing a significant role in shaping diaspora identity and engagement strategies. Virtual cultural festivals, facilitated by ICT, allow for widespread participation in cultural celebrations, thus preserving and promoting cultural heritage [1]. Furthermore, the paper examines the economic contributions of diaspora through digital remittances, crowdfunding for development projects, and the promotion of entrepreneurship and investments, highlighting the enhanced financial inclusion and economic development facilitated by ICT.

2. ICT Tools and Diaspora Connectivity

2.1. Social Media Platforms

The advent and proliferation of social media platforms like Facebook, Twitter, and Instagram have revolutionized how diaspora communities maintain their connections, both among themselves and with their countries of origin. A quantitative analysis involving user engagement data across these platforms was conducted to investigate the nature and extent of these interactions. The data revealed a significant uptick in both the frequency and depth of communication, evidencing not just casual conversations but also substantive exchanges on cultural, economic, and political issues relevant to the diaspora and their homelands. Employing the Network Analysis Model, the study mapped out the complex web of connections within diaspora communities on these platforms. This model uses graph theory to visualize relationships, where nodes represent individuals, and edges represent interactions between them. Through this analysis, it became evident that social media not only facilitates a vast network of connections but also significantly strengthens the bonds within these networks. The degree centrality measure, which quantifies the number of direct connections a node has, was markedly higher for individuals actively engaging in diaspora-centric groups or pages, underscoring the role of social media in fostering strong community ties. Furthermore, the application of the Betweenness Centrality measure revealed that certain individuals within these networks act as crucial bridges, linking various sub-groups within the diaspora and even between the diaspora and residents in the homeland [2]. These individuals often share information, news, and cultural content, playing a pivotal role in the dissemination of important narratives and fostering a sense of unity and shared identity. This analytical approach underscores the nuanced role that social media plays in diaspora engagement, far beyond mere communication, acting as a catalyst for cultural preservation and a forum for collective action.

2.2. Mobile Applications

The role of mobile applications in enhancing diaspora engagement cannot be understated, particularly in the realms of remittance transfers and cultural exchanges. A focused analysis was conducted on several mobile applications designed specifically for diaspora communities, such as those facilitating remittances, sharing news from homeland media outlets, and promoting language learning and cultural education. The study applied the Remittance Transfer Model, a quantitative framework that integrates variables such as transaction costs, transfer speed, and volume of remittances, to assess the impact of mobile apps on financial contributions to the homeland. The analysis revealed a significant reduction in transaction costs and transfer times associated with remittances sent through these mobile platforms, compared to traditional banking systems. For instance, the average cost of sending remittances through mobile apps was found to be up to 7% lower than through banks or traditional money transfer services, as shown in Table 1. Moreover, the speed of transactions saw a marked improvement, with funds typically available within 24 hours, as opposed to several days. This efficiency not only enhances the economic support diaspora can provide but also strengthens the emotional and relational ties to their homeland, as the act of remittance becomes a seamless part of their daily digital interactions. These mobile applications also serve as platforms for cultural education and engagement, offering courses in native languages, folklore, history, and cultural practices [3]. By employing a user engagement analysis, the study quantified the extent of interaction with these educational features, finding a notable increase in usage around cultural festivals and significant diaspora events. This suggests a deepening of cultural ties and identity among diaspora members, facilitated by the easy access and interactive nature of these mobile applications.

By employing advanced metadata standards and interactive user interfaces, digital archives enhance the discoverability and engagement with these artifacts, effectively bridging geographical and temporal gaps. One significant impact of digital archives is their ability to provide a multidimensional view of cultural heritage. Through virtual reality (VR) and augmented reality (AR) technologies, users can experience artifacts in immersive environments, offering insights into their historical context and cultural significance. This digital engagement facilitates a deeper connection with the heritage, particularly for younger generations within diaspora communities who may be geographically and culturally removed from their ancestral origins [5]. Furthermore, digital archives and museums utilize analytics tools to track user interaction, enabling curators to understand which artifacts resonate most with the audience. This data-driven approach helps in tailoring educational programs and exhibitions to the interests and needs of the diaspora community, thereby increasing cultural literacy and appreciation. The application of the Digital Engagement Model thus not only preserves cultural heritage but also enhances its relevance and accessibility, making it a cornerstone of ICT in cultural preservation efforts.

3.2. Virtual Cultural Festivals

Virtual cultural festivals have capitalized on the advancements in ICT to overcome geographical constraints, enabling diaspora communities to participate in cultural celebrations regardless of their physical location. Through the Event Participation Model, the organization of these festivals is analyzed, showcasing their effectiveness in fostering cultural exchange and community engagement. The model quantifies participation through metrics such as virtual attendance, active participation in cultural workshops, and social media interaction, providing insights into the reach and impact of these events:

\( EES=(\frac{VA}{VT})×AP×SI \) (1)

Where: EES = Event Effectiveness Score, a composite measure of the event's overall impact. VA = Virtual Attendance, the number of unique participants at the festival. VT = Total Invited, the total number of individuals invited or who were aware of the event, providing a context for the attendance rate. AP = Active Participation Score, a weighted average score representing the level of engagement in cultural workshops, Q&A sessions, etc., normalized to a scale (e.g., 0 to 1). SI = Social Interaction Score, derived from social media interactions related to the festival, including likes, shares, comments, and mentions, normalized to a scale (e.g., 0 to 1).

These virtual festivals often feature a blend of live-streamed and pre-recorded performances, cultural workshops, and interactive sessions that allow for real-time engagement between participants and organizers. The use of high-quality streaming platforms ensures a seamless viewing experience, while social media platforms facilitate discussions, sharing of experiences, and networking among participants, further enriching the festival experience. Feedback collected from participants underscores the value of these virtual cultural festivals in enhancing cultural knowledge, pride, and unity within the diaspora. The festivals serve not only as a platform for cultural display but also as an educational tool, introducing participants to the nuances of their cultural heritage through immersive experiences [6]. The Event Participation Model, by quantifying the reach and effectiveness of virtual cultural festivals, highlights their critical role in sustaining cultural ties and promoting cultural exchange in the digital age.

4. ICT and Economic Contributions to the Homeland

4.1. Remittance Flows

The advent of ICT has notably revolutionized the remittance landscape, enabling diaspora communities to send financial support back home with unprecedented speed and reduced costs. Traditional remittance channels often involved lengthy processing times and substantial transaction fees, hindering the frequency and volume of remittances. However, the introduction of digital remittance services, leveraging technologies such as blockchain and mobile payment platforms, has dramatically altered this scenario. The Remittance Flow Model, employed in this study, is based on a regression analysis of remittance data over the past decade, comparing periods before and after the introduction of major digital remittance services. This model incorporates variables such as transaction costs, transfer speed, and remittance volume to establish a clear correlation between the use of ICT and increased remittance flows. The findings indicate a statistically significant reduction in transaction costs by an average of 65% and a reduction in transfer time from days to minutes. Concurrently, there has been a noticeable increase in the volume of remittances, with a compounded annual growth rate (CAGR) of 12% post the adoption of digital remittance solutions. This growth not only signifies the direct economic impact on the recipient countries' economies, often contributing to a substantial portion of their GDP but also underscores the enhanced financial inclusion facilitated by ICT.
