“…In this paper we have provided empirically based examples of the contributions that palaeo-data can make to next generation IAMs that require enhanced provision for local and pro-active adaptations [ 300 ]. The detailed Digital Elevation Model (DEM) ( see Methods 1) and sea level history [ 100 ] that now exist for the Tràng An World Heritage Site contribute to the growing body of past sea level data now available for the RRD and regionally, and locally specific insights into the effects of predicted inundation. We underscored the relevance to future coastal change scenarios through comparison to past coastal configurations and through identification of eight modern foci (coastal change analysis, hydrometeorological risk, economic adaptation, ocean-climate systems and feedback, coastal stabilisation, ecosystem restoration, sediment transport and salinity intrusion) that can draw directly from the Holocene evolution of the RRD.…”

“…In addition to these data, one of the sources, Hoang et al [ 108 ], incorporated geomorphological proxies and shallow seismic sections into their model. Our own data from Tràng An [ 100 ] ( see Methods : 1) similarly, relies on geomorphological proxies, particularly corrosion notches ( Fig 2 ), supplemented by archaeological and coring data [ 109 ].…”

“…Based on current modelled expectations, a rate of sea level rise over 6.1 mm/year (i.e., that expected under the Representative Concentration Pathway (RCP)8.5 scenario for 2050) may exceed the tipping point at which mangroves are able to build vertically through sediment accretion [ 139 , 140 ]. Hydrological and microclimate conditions affecting the prehistoric establishment and long-term persistence of back-mangrove forest have been reported for the Tràng An massif [ 100 , 109 ]. This record runs contra to the wider deltaic observed trend for mangrove decline during the 6500–5000 cal.…”

“…Under all of the projected emissions scenarios in this section, the Tràng An massif will become coastal by 2150 ( Fig 6 ). This makes it an excellent ‘anchor-point’ [ 100 ] location to examine how palaeo-data can assist in creating locally attuned flood risk mitigation and conservation strategies. In the following sections we use palaeoenvironmental (mangrove), vertebrate zooarchaeological and zoological evidence from Tràng An, and highlight the critical importance of on-the-ground multi-stakeholder involvement, to spotlight how this can be achieved.…”

Over the past twenty years, government advisory bodies have placed increasing emphasis on the need for adaptive measures in response to the effects of human-induced climate change. Integrated Assessment Models (IAMs), which incorporate macroeconomic and climate variables, feature prominently in advisory content, though they rarely draw on data from outside strictly constrained hypothetical systems. This has led to assertions that they are not well-suited to approximate complex systemic human-environment processes. Modular, interdisciplinary approaches have offered a way to address this shortcoming; however, beyond climate records, prehistoric data continue to be under-utilised in developing such models. In this paper we highlight the contribution that archaeology and palaeoecology can make to the development of the next generation IAMs that are expected to enhance provision for more local and pro-active adaptations to future climate change. We present data from one of Southeast Asia’s most heavily developed river deltas: the Red River (Song Hong) Delta, in Vietnam and localised analysis from the Tràng An Landscape Complex World Heritage Site, on the delta’s southern margin. Comparison is made between Shared Socio-economic Pathways (SSP) 5–8.5 and SSP2–4.5 emission projection models and the Mid-Holocene inundation of the Red River Basin. We highlight the value to taking a scientific long view of coastal evolution through an illustrative set of eight research foci where palaeo-data can bring new and localised empirical data to bear on future risk management planning. We proceed to demonstrate the applicability of palaeoenvironmental, zooarchaeological and historical evidence to management and the development of sustainable conservation strategies using Tràng An as a case study. In so doing, we further highlight the importance of knowledge exchange between scientific, corporate, non-governmental, local, and state stakeholders to achieve tangible results on the ground.

In carbonate coastlines, karst studies have traditionally focused on reconstructing Quaternary coastal uplift and sea level oscillations. However, their potential for investigating coastal subsidence remains unexplored in regions with limited sedimentary records and scientific monitoring. In line with this, our study delved into the utility of karst research for deciphering the Quaternary evolution of the Granada coast in southern Spain—a shoreline marked by a conspicuous scarcity of records and information regarding recent tectonic movements. The current labelling data and the absence of evidence for uplift led to the hypothesis that the Granada coast may be susceptible to subsidence, though this conjecture remained unconfirmed. While submerged marine terraces were clearly identified, they were previously interpreted as consequences of sea‐level oscillations. Our multidisciplinary approach integrated karst vadose features, biostratigraphy, and the dating of 22 speleothems to address the potential uplifting or subsiding dynamics of the Granada coast. The findings indicated that the Granada coast experienced emersion between 3.5/2.4 Ma and 650 ka ago. Notably, this uplift predated similar occurrences in neighbouring coastal regions to the W and E, which occurred within the last 200–180 ka. These disparities in timing cannot be solely attributed to sea‐level fluctuations, suggesting the involvement of the tectonic activity during the Quaternary. The tectonic likely led to the emergence of the Granada coast and its karstification, followed by subsidence. Furthermore, we identified the extensional faults that caused the coastal subsidence, previously documented in studies conducted in nearby regions. However, until now, their specific impact on the Granada coast had not been comprehensively stated. In summary, our research introduces a novel application of classical karst investigations in the understanding coastal subsidence and the extensional active tectonic. By comparing vadose cave ages with established chronologies in adjacent coastal areas, this approach sheds light on the complex tectonic evolution of coastal regions.
