AbstractDepicting the temporal and spatial evolution pattern of global world cultural heritage systematically and finely is the basis of heritage recognition and protection. In this study, 869 world cultural heritage inscriptions (through 2019) were selected as the research objects, and the times and types of each World Heritage site were manually annotated from more than 5000 pieces of data. Through time series modelling, the advantages of and changes in heritage declarations in different regions and periods were analysed, and the impact of heritage strategy on the number of heritage sites included in each region was evaluated. The results showed that the implementation of heritage policy greatly impacted each region, especially on the number of heritage sites in Asia and the Pacific region. Using the heritage era to carry out modelling analysis, from the perspective of the integrity of historical heritage cultural types, it is considered that there may be cultural heritage sites in the Caribbean and Latin America that have not been given enough attention. The modelling analysis results of era attributes can support the fairness of heritage determination. By calculating the frequency and peak value of heritage sites at the national scale, the frequency and peak value of each country in the top 10 list are used to characterize the ability of national declarations of cultural heritage and reveal the differences in the ability of each member country to declare heritage sites and the heritage era. By calculating the distribution density of the heritage era, this study finds that the world’s cultural heritage is not concentrated in the Middle Ages (600–1450) but the periods of Reformation and Exploration (1450–1700) and Progress and Empire (1850–1914). The above analysis shows that there are imbalances and strategic adjustment effects concerning regions, countries, eras and types in World Heritage list development. The composition types of heritage are complex, and the combination types have obvious changes in different periods. It is suggested that the strategy of world cultural heritage collection should be further optimized to fully guarantee the balance of regions, countries and types, and the heritage value should be fully considered in heritage protection with more diversity and complexity of types.

Emergency Measures

In Algeria, several old urban nuclei are decayed or severely damaged. Numerous are the factors related to these damages: the age of constructions (many centuries), the bad or absence of maintenance, the natural disaster (earthquake, landslide, and floods) and sometimes the abandonment. Since 2003, the law 98-03 related to the preservation of cultural heritage and its application decree was implemented. In fact the first safeguard sector plan in Algeria was applied to the Casbah of Algiers which is classified as a World Heritage. This old urban nucleus presents an important decay. The different problems related to its aspect are principally the age of constructions; some of them date from the 10th century and the majority of the 16th; the absence of maintenance and recently in 2003 the impact of the earthquake. The project is still under investigation and is established by the CNERU Group (National Center in Urban Research and Studies). Furthermore the work on these areas was done under constraints. The Casbah of Algiers is a World Cultural Heritage, what induced us the installation of emergency measures (propping up), then in parallel an in situ investigation in order to determine the vulnerability of constructions was done (minor and major inheritance, houses and buildings) in order to elaborate the manual of rehabilitation and the safeguard plan and its regulation. This paper presents the adopted methodologies in this area and the different actions as the emergency measures, the constructions propping up and the manual of rehabilitation.

Abstract. The impact of changes in agricultural land use and practices as a controlling driver of hydrologic response and as a source of diffuse pollution, are studied in the Joumine River basin, discharging into the Ichkeul Lake, northern Tunisia, a UNESCO World Heritage site since 1979. The lake is characterized by a very specific hydrological functioning based on a seasonal alternation of water levels and salinity through its link to the Mediterranean Sea. Three Landsat images, in situ surveys and SWAT modelling were used to simulate and assess streamflows and nitrate loads under retrospective land uses.

The Impact

Compared to more traditional techniques, the application of Externally Bonded-Fibre Reinforced Polymers (EB-FRP) represents a viable alternative for the strengthening of masonry structures, also in case of Cultural Heritage buildings where strict requirements need to be met, aimed at minimizing the impact of the intervention. Since the FRP-to-masonry bond behaviour strongly affects design and effectiveness of such interventions, several investigations have been carried out in recent years to study this phenomenon, generally based on the longer experience developed for concrete substrates. Mortar joints, which are geometrical and mechanical discontinuities, distinguish and characterize masonry substrates from concrete ones, and therefore deserve a special attention as far as their role in the bond behaviour is not clarified yet. This paper, aimed at giving a contribution also from a methodological point of view, presents the main experimental results of shear tests carried out on glass composites (GFRP) applied to natural calcareous stones (pietra leccese), to lime mortar blocks and to masonry prisms made by coupling stones and lime mortar. Overall 22 shear tests were performed, keeping a bonded length of 200 mm for stones and mortar specimens while it was changed from 65 mm (corresponding to one stone and one mortar joint) to 195 mm (three stones and three mortar joints) in the case of masonry prisms. The effect of the FRP end anchorage on the test development was investigated as well, and results of the experimental tests are herein discussed in detail.

Abstract. In the Eastern Alps no previous research focused on the impact of wildfires on the occurrence of rockfalls. The investigation of wildfires and post-wildfire rockfalls gains new importance with respect to changes in weather extremes and rapid social developments such as population growths and tourism. The present work describes a wildfire that occurred in August 2018 in a famous world-heritage site in Austria. Indicators of fire severity and rockfall occurrence during and after the fire are described.

Using domestic tourism data (1999–2014) and inbound tourism data (1999–2016), this research applies linear and nonlinear models to investigate the impact of World Heritage Sites (WHS) on inbound and domestic tourism expansion (TE) in terms of tourist arrivals and tourism receipts and then tests whether or not the impact of WHS on TE is instant. The results show a notable influence of WHS on tourist arrivals and tourism receipts and identify several differences between the impacts of WHS on inbound and on domestic TE. Moreover, the relationship between WHS and TE exhibits an inverted U-shaped curve. The optimal number of WHS for TE is four, and there is a significant instantaneous effect of WHS on domestic TE. Differently, the impact of WHS on inbound tourism shows a 1-year lag. Lastly, we perform dynamic regressions as a robustness check and discussion and implications are provided.
