The article analyses the uneven geography of foreclosed housing owned by large private landlords in Catalonia. A Negative Binomial Model is applied to identify the local determinants of the concentration patterns of 32,941 housing units in Catalan cities. Indicators of socioeconomic vulnerability, such as the percentage of foreign population or the percentage of unemployed residents, are identified as key explanatory factors of the regional geography of housing accumulated by banks which, in turn, correspond to areas in which global corporate landlords are focusing their business for profiteering from the rental market in the current expansionist phase of the housing cycle. Our findings demonstrate that the concentration of properties in the most vulnerable areas was fuelled by foreclosures responsibility of banks rescued with public funds. In tandem, we provide detailed information for the understanding of the new scenarios that have emerged during the post-crisis phase.

After a successful conquest of large parts of Syria in 1258 and 1259 CE, the Mongol army lost the battle of cAyn Jālūt against Mamluks on September 3, 1260 CE. Recognized as a turning point in world history, their sudden defeat triggered the reconfiguration of strategic alliances and geopolitical power not only in the Middle East, but also across much of Eurasia. Despite decades of research, scholars have not yet reached consensus over the causes of the Mongol reverse. Here, we revisit previous arguments in light of climate and environmental changes in the aftermath of one the largest volcanic forcings in the past 2500 years, the Samalas eruption ~1257 CE. Regional tree ring-based climate reconstructions and state-of-the-art Earth System Model simulations reveal cooler and wetter conditions from spring 1258 to autumn 1259 CE for the eastern Mediterranean/Arabian region. We therefore hypothesize that the post-Samalas climate anomaly and associated environmental variability affected an estimated 120,000 Mongol soldiers and up to half a million of their horses during the conquest. More specifically, we argue that colder and wetter climates in 1258 and 1259 CE, while complicating and slowing the campaign in certain areas, such as the mountainous regions in the Caucasus and Anatolia, also facilitated the assault on Syria between January and March 1260. A return to warmer and dryer conditions in the summer of 1260 CE, however, likely reduced the regional carrying capacity and may therefore have forced a mass withdrawal of the Mongols from the region that contributed to the Mamluks’ victory. In pointing to a distinct environmental dependency of the Mongols, we offer a new explanation of their defeat at cAyn Jālūt, which effectively halted the further expansion of the largest ever land-based empire.

Here, we present fine-scale measurements of stem diameter variation from three common arctic-alpine dwarfshrub species monitored in two mountain regions of Central Norway. All three species (Betula nana, Empetrum nigrum ssp. hermaphroditum, and Phyllodoce caerulea) are abundant within the studied regions and highly important contributors to potential future arctic-alpine vegetation shifts. A profound understanding of their radial growth patterns therefore has the potential to yield crucial information regarding climate-growth relations within these ecosystems. We used high-resolution dendrometers (type DRO) to monitor 120 specimens, taking measurements near the shoot base of one major horizontal stem. Along with the shrub growth measurements, we measured on-site micro-environmental data at each studied site, including shoot zone and root zone temperatures as well as soil moisture. All data were recorded at an hourly scale and are presented as daily mean values. The monitoring period spanned five full years (2015 2019), with additional data from 2014 and 2020. Data were collected within one of the most continental climate regions of Europe, the Vågå/Innlandet region, and in the oceanic climate region Geiranger/Møre og Romsdal, spanning a steep climate gradient over just ~100 km horizontal distance. Both study regions are characterized by steep elevational gradients and highly heterogeneous micro-topography. The studied sites were chosen to represent these natural conditions using the transect principle. The collection of our original data is subject of our long-term alpine ecosystem monitoring program since 1991, from which numerous publications function as the basis for a recent project on the use of dendrometer data in alpine ecosystem studies.
在这里，我们对挪威中部两个山区监测到的三种常见的北极高山矮灌木的茎径变化进行了精细测量。所有三个物种（桦树、黑Empetrum nigrum ssp.雌雄同体和蓝叶Phyllodoce caerulea）在研究区域内都很丰富，对未来北极高山植被的潜在变化起着非常重要的作用。因此，深入了解它们的径向增长模式，有可能获得有关这些生态系统内气候增长关系的重要信息。我们使用高分辨率树木测量仪（DRO型）监测了120个标本，在一个主要水平茎的茎基附近进行了测量。除了灌木生长测量外，我们还测量了每个研究地点的现场微观环境数据，包括地上部和根部的温度以及土壤湿度。所有数据以小时为单位进行记录，并以日平均值表示。监测期为五年（2015年至2019年），2014年和2020年的额外数据。数据是在欧洲大陆性最强的气候区之一，Vågå/Insladet区和海洋性气候区Geiranger/Møre og Romsdal收集的，跨越了约100公里的陡峭气候梯度。这两个研究区域都具有陡峭的海拔梯度和高度不均匀的微观地形。选择研究地点是为了利用样带原理来代表这些自然条件。自1991年以来，我们的原始数据收集一直是长期高山生态系统监测计划的主题，其中许多出版物是最近一个关于在高山生态系统研究中使用树木测量仪数据的项目的基础。

The presented study is dedicated to the assessment of the scope and degree of anthropopressure, and the dependence of its intensity on the characteristics and nature of micro-environments. The research was based on the subfossil remains of molluscs. Eleven profiles of Late Holocene sediments in the Dulówka valley near Cracow were subjected to malacological analysis. In the upper part of the valley, there are calcareous tufas containing rich molluscan assemblages with a large share of shade-loving species. In the lower part, malacofauna dominated by open-country snails occurs in fluvial sediments. Radiocarbon dating has shown that mollusc-bearing deposits represent the last 2,000 years. The diversity of ecological features of molluscan assemblages in different parts of the valley depends on the intensity of anthropopressure. In the upper part, natural forest communities have survived to the present day, and anthropopressure has only been marked to a limited extent. The lower section has undergone a major transformation, mainly due to deforestation and the development of agricultural areas. Unfavorable terrain conditions for the human economy should be considered the major cause of the low anthropopressure intensity in the upper part of the valley. The malacological analysis used in the study allowed showing a significant diversity of microhabitats within the valley and its uneven susceptibility to human interference in natural processes.

Mobility-related challenges severely impact on everyday lives of families with young children. Since this is especially true for families with children younger than ten, here we focus on the mobility coping strategies and patterns they develop to reconcile family and work life. The paper is based on a qualitative empirical study in which 40 mothers and fathers were interviewed in the Ruhr region in 2018. The results show that their most pressing mobility challenges are related to time-based and financial restrictions. Common strategies in adapting to these challenges are commuting by car, by involving the grandparent generation in childcare, and by reducing the mother’s (paid) working hours. Especially the interviewed mothers see the latter as a compromise rather than a satisfactory measure. Families who cannot resort to these strategies might be faced with social exclusion.

Research on integration processes of migrants has until recently remained on geographical levels of observation which are not apt to reveal and explain the variety of local integration trajectories. Furthermore, most research has focused on the role of migrants within these processes, while the attitudes and behaviours of the receiving society have been rarely addressed. This research gap concerns in particular rural areas since those areas have been widely left out of migration research. This article addresses those research gaps and develops a concept for the empirical research of local receptivity processes.

When the COVID-19 pandemic unfolded, public health measures were implemented globally. Early on, concerns grew that lockdowns and travel restrictions could have severe consequences, especially for marginalized communities in the Global South. In Sub-Saharan Africa, wood charcoal is not only an important cooking fuel, but provides income for many rural households. Despite its economic value, the charcoal sector is, however, largely unregulated and viewed exclusively as an environmentally damaging industry by policy makers and the public who make it responsible for large-scale deforestation. The present study employs a sustainable livelihood framework to assess the ability of charcoal producers in northwestern Kenya, to cope with a short-term shock such as the COVID-19 pandemic and preventive measures. It furthermore compares their access to health information to that of non-producers. A street survey of 139 respondents allowed to gain rapid insights into the realities of a group not accessible via online or telephone surveys. The results show that 87% of charcoal producers face severe decline of this economic practice because of limited market access. These losses cause them food insecurities, while non-charcoal producers are more worried about social consequences of the restrictions. Though charcoal producers and non-producers feel equally well informed about the pandemic, producers are less likely to access reliable information channels than non-producers, resulting in an uneven distribution of health information across the community. By investigating the response of producers to an external shock and limited market access this study adds to the understanding of local vulnerabilities and the sustainability of rural livelihood strategies. This research argues for inclusive policy response to ensure consideration of the informal sector in crisis response as well as to provide adequate and low-threshold access to health information.
