“…From these, the rate and/or magnitude of shoreline movement can be calculated. This general approach has been extensively used for coastal management or geomorphological studies [61][62][63][64][65][66] and more recently also for archaeological vulnerability assessments [67][68][69][70][71][72].…”

The impact of coastal erosion on the archaeology of the Cyrenaican coast of Eastern Libya

Coastal erosion in Cyrenaica (Eastern Libya) represents a major problem for archaeology and heritage management. The area is rich in archaeological sites, often understudied or not fully documented, but also has extensive stretches of vulnerable eroding coastline. This study demonstrates the extent and impact of erosion via shoreline change assessment at two spatial scales. Firstly, wide area assessment using shorelines extracted from a time-series of medium-resolution Landsat imagery. Secondly, site-specific assessment using recent and historic Very High Resolution (VHR) satellite imagery. In both cases, extracted shorelines at different timesteps were compared using the Digital Shoreline Analysis System (DSAS) tool to quantify rates and magnitudes of shoreline movement. The results show extensive zones of erosion at and around the key ancient harbour sites of Apollonia, Ptolemais and Tocra. They also suggest increased rates of coastal retreat in recent years, which is likely linked to anthropogenic actions such as sand mining and urbanization. Forecasts based on present-day shoreline change rates, coupled with ground-level documentation of the vulnerable shorelines is used to identify archaeological features and structures which will likely be progressively damaged or destroyed over the next 20 years. The ability to actively protect archaeological sites is unclear, but there is a clear need for mitigation in the form of enhanced awareness of environmental problems (e.g. caused by sand mining) and more intensive survey/documentation of sites and areas which will be lost in the coming years.

“…Digitised shoreline proxies can then be compared in Geographical Information Systems (GIS) to determine the rate and pattern of shoreline movement (i.e., coastal erosion or accretion) over time and space (Moore 2000; Thieler and Danforth 1994). The approach is well established in coastal management and geomorphological studies and has also been adopted by archaeological vulnerability assessments (Hil 2020; O'Rourke 2017; Westley 2019).…”

Endangered maritime archaeology in North Africa – the MarEA Project

2023

Increasing pressure – such as from conflict, climate change and urbanisation – on maritime cultural heritage in the Middle East and North Africa (MENA) led to the establishment of the Maritime Endangered Archaeology (MarEA) Project in 2019. This five-year programme aims to assess rapidly and comprehensively the vulnerability of maritime and coastal heritage in the MENA region and assist in its management in the face of the aforementioned challenges. The two case studies discussed in this article highlight some of the main aspects of MarEA's current work in North Africa by focusing on two different aspects of the methodological approach used: first, the generalised but comprehensive damage and threat assessment, as applied to all sites, and demonstrated for the historic port of Suakin (Sudan); second, site-specific shoreline change assessment for the purpose of assessing the impact of coastal erosion, as demonstrated for the World Heritage Site of Sabratha (Libya).

Indonesia is one of the countries with the largest area of tropical peatlands in the world. These wide peatlands have a vital role in the carbon cycle and carbon storage in huge quantities, thus strict conservation in the area is necessary. One effort to carry out conservation is to understand the spatial distribution of carbon stock in peatlands. This study aims to map the spatial distribution of carbon stock based on peat thickness modeling using machine learning algorithms, i.e., Random Forest (RF), Quantile Regression Forests (QRF), and Cubist. A case study was conducted in a part of Lake Sentarum National Park, Indonesia where human interference is still limited. Digital elevation model (DEM) and synthetic aperture radar (SAR) data were included as the input variables. The results showed that RF performed the best among other models to estimate peat thickness (mean = 1.877 m) with an RMSE (root mean square error) of 0.483 m and an R 2 of 0.786. DEMs are the most important parameters in our analysis compared to SAR data. Based on the best model, we estimated the total volume of 5,112,687 m 3 in the study area, produced at 12.5 m resolution, which was then converted to a total of carbon stock at 0.337 ± 0.106 Mt carbon.
