Deltaic regions across the world are often densely populated and support much of the world’s fisheries, forest products and agriculture. Protecting livelihoods and ecosystem services in deltas is therefore of global importance. Among them, Ganga Brahmaputra delta, the world’s largest and most populated delta, represents a critical hotspot for ecological vulnerability and risk to human life. It faces challenges caused by climate-induced problems such as increased inundation frequency, erosion, habitat loss and recent intensification of sea level rise and salinity intrusion. This chapter offers a two-fold contribution: first, it endeavors to facilitate an indepth overview of the current landscape surrounding Delta resilience, ultimately aiming to delineate future avenues for investigative research in this realm. Second, it provides an in-depth overview of Nature Based Solutions (NBS) applications in the Ganga–Brahmaputra delta for flood and erosion control. Employing R software through Bibliometrics alongside tools such as Vosviewer and Zotero, we performed a comprehensive bibliometric analysis. This enabled us to assess pivotal keywords, influential authors, publication trends, research clusters and countries pertinent to the field of delta resilience. Results highlight an increasing global focus on ecosystem-based approaches, wetland restoration, mangrove reforestation, and community-based adaptation within delta regions. The second part of the chapter delves into the socio-ecological dynamics of the Ganga–Brahmaputra delta, emphasizing its exposure to frequent floods, riverbank erosion, and salinization. It examines the role of traditional knowledge systems and locally-embedded NBS—such as mangrove regeneration, embankment greening, floodplain zoning, and sediment management—in enhancing resilience. The discussion critically evaluates the scalability, challenges, and co-benefits of these strategies in relation to regional policies and international climate frameworks. By synthesizing global bibliometric insights and contextual realities from the Indian subcontinent, this chapter aims to contribute to the evolving discourse on sustainable delta management, emphasizing the need for integrated, adaptive, and community-led nature-based approaches. This analysis culminates in a systematic encapsulation of the prevailing research findings concerning delta resilience, predicting future trends with Indian research spectrum.
