Abstract This study focusses on a short-term characterisation of atmospheric aerosols from three locations in southeast of Poland with different land use characteristics, population density and sources of pollution (Katowice: urban-industrial; Strzyżowice near Lublin: rural; Kielce: urban). Twenty-four hour PM2.5 and PM10 samples were collected on the quartz filter and their chemical compositions were monitored and measured using OCEC thermo-optical analysis and scanning electron microscopy-energy dispersive X-ray spectrometry (SEM-EDS). The highest concentrations of PM2.5 and PM10 were measured at the urban-industrial area in Katowice (29.6 µg ∙ m−3 and 31.0 µg ∙ m−3, respectively), whereas the highest organic carbon (OC) and elemental carbon (EC) levels were observed at the Kielce urban site (23.3 ± 4.2 µg and 3.6 ± 0.3 µg, respectively). The lowest values were obtained at the rural site for PM2.5 (10.4 ± 2.7 µg ∙ m−3) and PM10 (11.8 ± 2.7 µg ∙ m−3) and for OC (17.8 ± 1.6 µg) and EC (1.0 ± 0.1 µg). SEM-EDS analysis of samples from Kielce allows identification of internal chemical mixtures of carbon, silicon, calcium, chlorine, sodium and aluminium.

Abstract The development of geotourism in the Holy Cross Mountains region has a long tradition based on the scientific and educational geological values of this area. In order to evaluate geotourism resources and their development in three representative areas of Świętokrzyskie voivodeship – the Holy Cross Mountains UNESCO Global Geopark (GGp), the central part of the Holy Cross Mountains and the Kamienna River Valley – a review of the literature and statistical data, and field studies of geosites and educational units were carried out. The Holy Cross Mountains UNESCO GGp is a first-rate geotourism region, which plays a leading role in geotourism and geoeducation, promoting geological values and infrastructure development. The central part of the Holy Cross Mountains and the Kamienna River Valley are classified as second-rate regions. The remaining areas of Świętokrzyskie voivodeship, with its unique geodiversity and biodiversity, are still waiting for their geological attractions to be discovered and shared with the broader public.

Abstract Prioritisation of sub-watersheds (SWs) is becoming increasingly important in the conservation of natural resources, particularly in watershed planning. In this study, sub-watershed for the Neyyar basin was prioritised using three methods: morphometric analysis, principal component analysis (PCA) and hypsometric analysis. Morphometric analysis and hypsometric analysis were carried out using remote sensing (RS) and geographic information system (GIS) techniques, while PCA was performed for dimensionality reduction of morphometric parameters. The watershed was divided into 11 sub-watersheds (SW1–SW11), and each sub-watershed was given priority. To rank and prioritise SWs, 15 morphometric parameters were selected from the quantitative measures of morphometric analysis, including linear, relief, and areal. PCA was used to rank and prioritise SWs based on three highly correlated morphometric parameters. The hypsometric integral (HI) values were determined using the elevation relief ratio approach, and HI values were utilised to prioritise SWs. For both methods, such as morphometric analysis and PCA, a higher priority has been given to SW1. Using hypsometric analysis, higher priorities have been assigned to SW1, SW7, SW8, SW9, SW10 and SW11. The most common SWs that belong to the same priority of SWs and have a high correlation between them among the three methods are SW1, SW2, and SW5.The results of this analysis indicate that SW1 is a common high priority area with a significant risk of soil erosion, runoff and peak discharge. Therefore, decision-makers may utilise the high-priority sub-watershed to guide planning and development, measure conservation efforts and manage the land to prevent.

Abstract The current study was based on sunshine duration data from 13 European stations during 1901–2018. It was found that the variability in the annual total sunshine duration (SD) over Europe is related to the variability in the component of the surface thermohaline circulation in the North Atlantic (NA THC). Positive NA THC phases (the condition of the ‘warm’ North Atlantic) correspond to the periods of increased SD (brightening), while negative phases correspond to the periods of decreased SD (dimming). These relationships remain stable and statistically significant. The mechanism of these relationships is based on the influence of weakened or enhanced heat flow from the ocean to the atmosphere on the course of the mid-tropospheric circulation processes. In periods of positive thermohaline circulation in the North Atlantic (NA THC) phases, the share of long waves (macrotype W according to the Wangengejm–Girs classification) increases, with the occurrence of which the frequency of anticyclonic weather over Europe increases, whereas in the periods of negative NA THC phases, the share of shorter waves (macrotypes E and C) increases, with the occurrence of which the frequency of cyclonic (frontal) weather over Europe increases. It is characterised by increased layer cloud cover, limiting the SD. Thus, along with changes in the thermal condition of the North Atlantic, the structure of cloud cover over Europe changes and becomes a factor regulating long-term changes in the annual total SD.

Abstract The state of Himachal Pradesh in India is one of the most important hotspots when it comes to landslides; and Kandaghat, a tehsil in the Solan district of Himachal Pradesh having religious and tourism importance, is substantially affected by frequent landslides causing road blocking. In the present study, the analytic hierarchy process (AHP) and certainty factor (CF) techniques, which form part of the geographic information system (GIS)-based landslide susceptibility models, were used to prepare a landslide susceptibility map for the Kandaghat region, for which, as a preliminary step, an inventory of 214 live landslides was prepared from the Bhukosh data directory. The landslide inventory was cross-verified on the Google Earth platform. About nine landslide causative factors (slope, curvature, aspect, soil, rainfall, land use–land cover, lithology, drainage density and lineament density) were considered for the study area, and against the backdrop of these, the corresponding thematic maps were prepared and used in turn for the preparation of the final landslide susceptibility map. Based on the two mentioned techniques, the thematic maps were assigned weights according to their prominence and dynamic processes in the study area. The model performance for each method was evaluated using the area under the curve (AUC), and the accuracies for the AHP and CF were ascertained as, respectively, 81% and 85.6%. The Himalayan terrains are significantly prone to landslides, and this study outlines the characteristics of one of the important Himalayan towns in terms of vulnerability for landslides, together with providing its classification in terms of slope deformation susceptibility; this procedure can help direct attention towards areas needing to be classified under high to very high landslide susceptibility zones.

Abstract The main goal of the article is to present the morphological changes that occurred in the Old Town of Wrocław in the post-war period. Morphological transformation is a natural process that shapes the external and the internal structure of a city. The damage inflicted during World War II interrupted the natural development of the burgage cycle and deeply altered the landscape of the city. Through the analysis of building coverage within street blocks, a classification of street blocks was obtained. On this basis, eight areas that underwent analogous phases of the burgage cycle in particular blocks were distinguished; this made it possible to identify the processes that can affect changes in morphology. The main analysis of the study was conducted using cartographic materials from 1934 to 2019 (through Conzenian methods), which visualised the distribution of buildings within street blocks.

Abstract The creative sector is one of the most rapidly growing sectors of the global economy. This sector can also play an important role in providing economic benefits for developing countries. Promoting the creative economy needs a better understanding of the underlying factors that account for its spatial distribution. One of the most important factors that may influence the development of creative industries is tolerance. This paper focuses on the spatial distribution of the creative economy across cities in Indonesia and examines its relationship with tolerance. The main data sources of this paper are the unique data produced by the Central Bureau of Statistics (Badan Pusat Statistik or BPS) and the Indonesian Agency for Creative Economy (Badan Ekonomi Kreatif or BEKRAF), in addition to the City Tolerance Index provided by the SETARA Institute. The study finds that the creative economy in Indonesia does not tend to have a high spatial concentration, indicating that cities in Indonesia have an opportunity to develop the creative economy. The analysis confirms that tolerance matters for the creation of the creative economy in Indonesia. Three components of the City Tolerance Index that influence the creative economy are the Mid-Term Regional Development Plan, discriminatory regional rules and incidents of abuses against the freedom of religion or belief. The size of the population, the Human Development Index, and the status of a city as the provincial capital play a significant role in explaining the distribution of creative economies across the cities in Indonesia.
创意产业是全球经济中发展最为迅速的产业之一。这个部门也可以在为发展中国家提供经济利益方面发挥重要作用。促进创意经济需要更好地了解影响其空间分布的潜在因素。影响创意产业发展的最重要因素之一是宽容。本文重点研究了印尼创意经济在城市间的空间分布，并考察了其与宽容的关系。本文的主要数据来源是中央统计局(Badan Pusat Statistics或BPS)和印度尼西亚创意经济局(Badan Ekonomi Kreatif或BEKRAF)提供的独特数据，以及SETARA研究所提供的城市容忍度指数。研究发现，印尼创意经济的空间集中度不高，说明印尼城市有发展创意经济的机会。分析证实，宽容对印尼创造创意经济至关重要。影响创意经济的城市容忍指数的三个组成部分是中期区域发展计划、歧视性区域规则和侵犯宗教或信仰自由的事件。人口规模、人类发展指数和一个城市作为省会的地位在解释印尼创意经济在各个城市的分布方面发挥着重要作用。
