1. Rethinking the Landscape: Emerging Approaches to Archaeological Remote Sensing

   An emerging arena of archaeological research is beginning to deploy remote sensing technologies—including aerial and satellite imagery, digital topographic data, and drone-acquired and terrestrial geophysical data—not only in support of conventional fieldwork but also as an independent means of exploring the archaeological landscape. This article provides a critical review of recent research that relies on an ever-growing arsenal of imagery and instruments to undertake innovative investigations: mapping regional-scale settlement histories, documenting ancient land use practices, revealing the complexity of settled spaces, building nuanced pictures of environmental contexts, and monitoring at-risk cultural heritage. At the same time, the disruptive nature of these technologies is generating complex new challenges and controversies surrounding data access and preservation, approaches to a deluge of information, and issues of ethical remote sensing. As we navigate these challenges, remote sensing technologies nonetheless offer revolutionary ways of interrogating the archaeological record and transformative insights into the human past.

2. Thirty-Two Years of Integrating Archaeology and Heritage Management in Belize: A Brief History of the Belize Valley Archaeological Reconnaissance (BVAR) Project’s Engagement with the Public

   Since its inception in 1988, the Belize Valley Archaeological Reconnaissance (BVAR) Project has had two major foci, that of cultural heritage management and archaeological research. While research has concentrated on excavation and survey, the heritage management focus of the project has included the preservation of ancient monuments, the integration of archaeology and tourism development, and cultural heritage education. In this paper, we provide a brief overview on the history of scientific investigations by the BVAR Project, highlighting the project’s dual heritage management and research goals. This background offers the basis in which to discuss the successes and challenges of the project’s efforts in cultural heritage management and public engagement, particularly in early conservation efforts, in its training and educational efforts, and its ongoing outreach activity. We emphasize the need to train Belizeans as professional archaeologists and conservators, to serve as the next generation of advocates for Belize’s heritage management. We offer some ideas on how research projects can make significant contributions to heritage education and preservation in the developing world.

3. Virtual cultural landscapes: Geospatial visualizations of past environments

   https://doi.org/10.1002/arp.1830  

   Monteleone, Kelly; Thompson, Amy E.; Prufer, Keith M. (May 2021, Archaeological Prospection)

   Abstract Recent advances in spatial and remote sensing technology have led to new methods in archaeological site identification and reconstruction, allowing archaeologists to investigate landscapes and sites on multiple scales. These remotely conducted surveys create virtual cultural landscapes and seascapes that archaeologists and the public interact with and experience, often better than traditional maps. Our study examines landscape reconstruction and archaeological site classifications from a phenomenological and human behavioural ecology (HBE) perspective. HBE aims to reconstruct how humans interacted with these places as part of their active and passive decision making. Through temporal reconstructions, archaeologists and others can experience and interpret past landscapes and subtle changes in cultural land‐ and seascapes. Here, we evaluate the use of remotely sensed data (lidar, satellite imagery, sonar, radar, etc.) for developing virtual cultural landscapes while also incorporating Indigenous perspectives. Our study compares two vastly different landscapes and perspectives: a seascape in coastal Alaska, USA, and a neotropical jungle in Belize, Central America. By incorporating ethnographic accounts, oral histories, Indigenous traditional knowledge and community engagement, archaeologists can develop new tools to understand decisions made in the past, especially pertaining to settlement selection and resource procurement. These virtual reconstructions become cognitive images of a possible place that the observer experiences. Virtual cultural landscapes allow archaeologists to reproduce landscapes that may otherwise be invisible and present them to different publics. These processes elucidate how landscapes changed over time based on human behaviours while simultaneously allowing archaeologists to engage with Indigenous communities and the public in the protection of prehistoric and historic sites and sacred spaces through cultural heritage management.

4. Modeling the potential impact of storm surge and sea level rise on coastal archaeological heritage: A case study from Georgia

   https://doi.org/10.1371/journal.pone.0297178

   Climate change poses great risks to archaeological heritage, especially in coastal regions. Preparing to mitigate these challenges requires detailed and accurate assessments of how coastal heritage sites will be impacted by sea level rise (SLR) and storm surge, driven by increasingly severe storms in a warmer climate. However, inconsistency between modeled impacts of coastal erosion on archaeological sites and observed effects has thus far hindered our ability to accurately assess the vulnerability of sites. Modeling of coastal impacts has largely focused on medium-to-long term SLR, while observations of damage to sites have almost exclusively focused on the results of individual storm events. There is therefore a great need for desk-based modeling of the potential impacts of individual storm events to equip cultural heritage managers with the information they need to plan for and mitigate the impacts of storm surge in various future sea level scenarios. Here, we apply the Sea, Lake, and Overland Surges from Hurricanes (SLOSH) model to estimate the risks that storm surge events pose to archaeological sites along the coast of the US State of Georgia in four different SLR scenarios. Our results, shared with cultural heritage managers in the Georgia Historic Preservation Division to facilitate prioritization, documentation, and mitigation efforts, demonstrate that over 4200 archaeological sites in Georgia alone are at risk of inundation and erosion from hurricanes, more than ten times the number of sites that were previously estimated to be at risk by 2100 accounting for SLR alone. We hope that this work encourages necessary action toward conserving coastal physical cultural heritage in Georgia and beyond.

5. Open-Access Archaeological Predictive Modeling Using Zonal Statistics: A Case Study from Zanzibar, Tanzania

   https://doi.org/10.5334/jcaa.107  

   Alders, Wolfgang (February 2023, Journal of Computer Applications in Archaeology)

   This paper presents a case study using zonal statistical analysis for archaeological predictive modeling with open-access software and free geospatial datasets. The method is applied to the rural landscapes of Zanzibar, Tanzania on the Swahili Coast. This study used QGIS (version 3.28) to perform zonal statistical analyses of environmental datasets weighted by settlement classes digitized from a 1907 historical map, to create predictive models for settlement across the island. These models were compared against the locations of major precolonial archaeological sites on the island and site data from a random stratified archaeological survey in an environmentally diverse region of northern Zanzibar. The results show strong correspondences between larger permanent site locations and areas of high likelihood for site detection in the predictive model. Additionally, there were correspondences between areas of lower likelihood for site detection and smaller, ephemeral sites related to agricultural production in swidden field plots. These results attest to Swahili rural complexity and enable an understanding of the specific environmental affordances that structured settlement and land use over the last millennium, in ways that shaped colonial contact in rural areas and altered the sociopolitical development of Zanzibar and the East African coast. The methods described here may be applicable for researchers and heritage managers in Africa and the Global South, where funding for large-scale field projects, expensive satellite imagery, or software licensing is limited.
