Sukur is a World Heritage Site located in Madagali Local Government Area of Adamawa State, Nigeria which was inscribed into the World Heritage List in 1999. Twenty-five (25) years after, this study aims to assess landscape changes in the face of recent natural and anthropogenic threats. In December 2014, Sukur was ravaged by armed conflict by insurgents. Moreover, the negative impacts of climate change are evident in some of the cultural features that make up the cultural landscape. The study employed the use of earth observation data from Google Earth Pro to perform land use and land cover change analyses. Satellite image data were accessed using the time slider tool in Google Earth Pro to extract images for four epochs - 2009, 2014, 2019 and 2023. Seven land use land cover types (bare land, built-up, cropland, footpath, terrace, tree, and water) were identified in this study and Random Forest machine learning algorithm was utilized in QGIS using EnMAP plugin to classify each land use and cover class of interest. Accuracy assessments were computed from confusion matrix, user accuracy, producer accuracy, overall accuracy and kappa coefficient. Change detection was then carried out using SCP plugin in QGIS to estimate how each land cover class changed for each epoch. The results of the analyses showed an expansion in built-up areas in all the epochs studied, reduction in vegetation between 2009 and 2014 and conversely, increase in cropland area through all the epochs which is attributable to anthropogenic factors of development and population growth. The main drivers of landscape change are increase in population, suburban development, lifestyle change and effect of climate change on the environment.</div></div>","PeriodicalId":15480,"journal":{"name":"Journal of Cultural Heritage","volume":"77 ","pages":"Pages 168-177"},"PeriodicalIF":3.3,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145691024","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To reconstruct the village’s townscape, we conducted a high-resolution microtopographic survey using multibeam echo sounder (MBES) data and generated CS 3D maps for spatial analysis. By comparing these results with historical cadastral maps, we identified the locations of land parcels, roads, irrigation canals, and tree-lined pathways. Topographic analysis revealed that residential areas were situated at the fan toe of an alluvial cone, agricultural fields in the mid-fan area, and irrigation canals along the fan’s base. This spatial organization suggests that the settlement was strategically designed to exploit the area’s hydrological characteristics. However, the accumulation of lake sediments since the eruption has obscured microtopographic features on the southern side of the site, preventing confirmation of the townscape in that area and the precise course of the former river.

Following field surveys of the Ming Great Wall in Shanxi Province, four scaled-down earthen walls were fabricated to support the growth of selected native plants on the top surfaces. Long-term monitoring revealed that the earthen walls covered by natural capping, especially native herbs with more biomass, could effectively influence thermal behaviour and moisture movement of the earthen walls, thus providing sustainable preservation effects in semi-arid regions. Compared with bare wall, natural capping reduced the number of freeze-thaw cycles at the top of the wall by 41.2 % in winter, decreased the average rate of temperature increase by 47.2 % in summer, and reduced the daily temperature difference and the temperature gradient between the range of 0 and 20 cm. Under the effects of rainfall, natural capping effectively stabilizes the moisture content in winter, decreases moisture fluctuation frequency by >61.9 % and delays the start time of moisture infiltration in the interior walls during summer. After one year of outdoor monitoring, the total loss of earth material was reduced significantly by 82.5 %.

Here, we investigate the physicochemical characteristics of the biodeteriorated brick heritage of the Nanjing Ming City Wall, unravel the correlations between microbial communities and physicochemical parameters, and explore the key taxa that drive the biodeterioration divergence. Despite being sampled in the same area, physicochemical analysis indicated a significant divergence in the deterioration of the brick heritage. Microbial structures suggested that the predominant phyla are Acidobacteriota, Cyanobacteria, Gemmatimonadota, Proteobacteria, Chloroflexi, and Actinobacteriota, highlighting Acidobacteriota and Chloroflexi as the key players that shape the divergence in biodeterioration. Moreover, the correlations between microbial communities and physicochemical parameters confirmed that members of Acidobacteriota and Chloroflexi contribute to the biodeterioration divergence, probably through denitrification and nitrification. Given that the biodeteriorated bricks are situated in the same environment, we claim that the in-situ microenvironment that microbial colonizers might shape could, in turn, affect biodeterioration.
