<p>Numerous studies worldwide have reported a dramatic increase in soil erosion rates following the development of agriculture. In Western Europe, food security issues led to an intensification of agricultural practices after World War II. A profound modification of the landscapes was operated that translated into an increase in hydrosedimentary connectivity and a decrease in soil cover in winter. Related on-site soil degradation and off site societal and environmental detrimental effects rapidly started to call for the implementation of conservation measures. Since 2000, the French water agencies, through the European water framework directives, started to fund the implementation of soft hydraulic conservation measures, such as vegetated filter strips or linear vegetation barriers. These measures have the advantage to be easily implemented and to be visible in the landscape without compromising the intensive agriculture production system. After twenty years of funding of soft hydraulic conservation measures, soil erosion is still an issue. Are these solutions just a plaster on a wooden leg or are they really effective? Recent efforts consisting in catchment scale monitoring programs and modelling exercise tend to show that soft hydraulic conservation measures may be usefull for local mitigation actions but may have a limited impact in terms of floods and muddy floods. On the basis of simulation exercises in contrasting environments we will discuss the advantages and limitations of such measures.</p>

Like people born shortly after World War II, the international human rights movement recently had its sixty-fifth birthday. This could mean that retirement is at hand and that death will come in a few decades. After all, the formulations of human rights that activists, lawyers, and politicians use today mostly derive from the UN Universal Declaration of Human Rights, and the world in 1948 was very different from our world today: the cold war was about to break out, communism was a strong and optimistic political force in an expansionist phase, and Western Europe was still recovering from the war. The struggle against entrenched racism and sexism had only just begun, decolonization was in its early stages, and Asia was still poor (Japan was under military reconstruction, and Mao's heavy-handed revolution in China was still in the future). Labor unions were strong in the industrialized world, and the movement of women into work outside the home and farm was in its early stages. Farming was less technological and usually on a smaller scale, the environmental movement had not yet flowered, and human-caused climate change was present but unrecognized. Personal computers and social networking were decades away, and Earth's human population was well under three billion.

Heinrich Himmler, August Heißmeyer, and the NPEA Inspectorate were eager to create a transnational empire of Napolas and ‘Reichsschulen’ in all of the territories occupied by Nazi Germany during World War II. These schools both mirrored and contributed to broader National Socialist occupation and Germanization policies throughout Eastern and Western Europe. They were intended to create a cadre of ‘Germanic’ or ‘Germanizable’ leaders, loyal above all to the SS. The chapter begins by exploring the genesis of the Reichsschulen in the occupied Netherlands—Valkenburg and Heythuysen—which were adopted as a ‘Germanic’ prestige project by the Reich Commissioner of the Netherlands, Arthur Seyß-Inquart. The chapter then turns eastwards to consider the role of the Napolas which were established in the conquered Czech and Polish lands, focusing on NPEA Sudetenland in Ploschkowitz (Ploskowice), NPEA Wartheland in Reisen (Rydzyna), and NPEA Loben (Lubliniec). All in all, the Napola selection process in the occupied Eastern territories can be seen as the peak of all the ‘racial sieving’ processes which the Nazi state forced ‘ethnic Germans’ (Volksdeutsche), Czechs, and Poles to undergo, inextricably bound up with the Third Reich’s wider race, resettlement, and extermination policies. The ultimate aim of all of these schools was to mingle Reich German and ‘ethnic German’ or ‘Germanic’ pupils, educating the two groups alongside each other, in order to create a unified cohort of leaders for the future Nazi empire, and to reclaim valuable ‘Germanic blood’ for the Reich.

By 1945, the spectre of Americanisation had been haunting Europe for half a century. With the United States still struggling to establish colonial rule over the Philippine Islands, European observers began framing the ‘American challenge’ as a cultural and most of all economic threat to national independence. Controversies about the impact of ‘America’ often served as a stand-in for a more fundamental reckoning with processes of modernisation. The initial period of sustained Americanisation was the 1920s, when American film, music, and automobiles were conquering Europe for the first time. A second heyday of Americanisation ‘from below’ started with the ‘American occupation of Britain’ and that of continental Europe during and after World War II. This article focuses on Western Europe and Americanisation, highlighting Americanisation from above and Americanisation from below. It looks at two concepts that often come up within debates about Americanisation: Westernisation and anti-Americanism.

The research on comparative immigration policy is relatively recent, with the earliest dealing with significant immigrant inflows into Western Europe after World War II. Because of the difficulties in finding empirically grounded measures of immigration policy, the literature has grown primarily by adding to the theoretical literature. In terms of the immigration control literature, nativism (anti-immigrant preferences) has been complemented by approaches that include attention to the economic consequences of immigration, focus on how societal preferences are channeled, and focus on state national interest and state security. In terms of the immigrant integration literature, there has been a tendency to classify the immigrant reception environment of states according to historical nation building features of the state and to types of “immigration regimes.” More recently, in recognition of the static nature of these models of policy making, scholars have disaggregated integration policy into its component parts and incorporated aspects of politics that change over time. The research arena is, in short, theoretically rich, though both dimensions of research on immigration policy suffer from two flaws. The first is the inability to compare effectively policies across countries. The second is the research focus on Western Europe and advanced industrial countries, to the neglect of the remaining countries in the world.

<p>Although fine-grained sediment (FGS) is a natural component of river systems, increased fluxes can impact FGS levels to such an extent they cause detrimental, irreversible changes in the way rivers function intensifying flood risk and negatively affecting water quality.</p><p>Previous catchment scale studies indicate there is no simple link between areas of sediment loss and the organic carbon (OC) load in waterways; areas with a high soil loss rate may not contribute most sediment to the rivers and areas that contribute the most sediment may not contribute the most OC. Anthropogenic and climate changes can accelerate soil erosion and the role of soil OC transported by erosional processes in the fluxes of C between land, water and atmosphere is still debated. Tracing sediment pathways, likely depositional areas and connections to streams leads to better assumptions about control processes and better estimation of OC fluxes.</p><p>In this innovative study OC fingerprinting of sediment reaching a catchment’s waterbodies is combined with OC stock and erosion modelling of the terrestrial catchment. Initial results show disconnect between catchment OC loss erosion modelling and fingerprinting results, which could be due to failure to model connectivity between the land and river channel. The current soil erosion model RUSLE (Revised Universal Soil Loss Equation) calculates only the spatial pattern of mean annual soil erosion rates. Using the WaTEM SEDEM model, which in includes routing (and possible en route deposition) of eroded sediments to river channels, we aim to determine the dominant source of OC within catchment streams by identification of both the land-use specific areas with the highest OC loss and the transport pathways between the sources and river channel.</p>

Self-sustaining, technologically based growth has always been accompanied by a process of financial transition which, as defined by Raymond Goldsmith, entails an increase in the financial superstructure to a status in the economy comparable to that in the leading countries of North America and Western Europe. The pattern of development along this transitional path may, of course, differ, as for example in the relative contribution of bank- or market-based financial systems. But all countries, Goldsmith observed, trace a similar transitional path in the increase in their superstructure of financial instruments and institutions relative to an infrastructure of output and wealth. Because of the close relationship between financial transition and modern economic growth as defined by Simon Kuznets, differences in speed at which countries traverse Goldsmith's transitional path are critical.

Following the shift in therapy of tuberculosis in the mid-19th century, by the beginning of the 20th century numerous tuberculosis sanatoria were established in Western Europe. Being an institutional novelty in the medical practice, sanatoria spread within the first 20 years of the 20th century to Central and Eastern Europe, including the southern region of the Panonian plain, the present-day Province of Vojvodina in Serbia north of the rivers Sava and Danube. The health policy and regulations of the newly built state - the Kingdom of Serbs, Croats and Slovenians/Yugoslavia, provided a rather liberal framework for introducing the concept of sanatorium. Soon after the World War I there were 14 sanatoria in this region, and the period of their expansion was between 1920 and 1939 when at least 27 sanatoria were founded, more than half of the total number of 46 sanatoria in the whole state in that period. However, only two of these were for pulmonary diseases. One of them was privately owned the open public sanatorium the English-Yugoslav Hospital for Paediatric Osteo-Articular Tuberculosis in Sremska Kamenica, and the other was state-run (at Iriski venac, on the Fruska Gora mountain, as a unit of the Department for Lung Disease of the Main Regional Hospital). All the others were actually small private specialized hospitals in 6 towns (Novi Sad, Subotica, Sombor, Vrbas, Vrsac, Pancevo,) providing medical treatment of well-off, mostly gynaecological and surgical patients. The majority of sanatoria founded in the period 1920-1939 were in or close to the city of Novi Sad, the administrative headquarters of the province (the Danube Banovina at that time) with a growing population. A total of 10 sanatoria were open in the city of Novi Sad, with cumulative bed capacity varying from 60 to 130. None of these worked in newly built buildings, but in private houses adapted for medical purpose in accordance with legal requirements. The decline of sanatoria in Vojvodina began with the very outbreak of the World War II and they never regained their social role. Soon after the Hungarian fascist occupation the majority of owners/ founders were terrorized and forced to close their sanatoria, some of them to leave country and some were even killed or deported to concentration camps.

Rainfall induced landslides and soil erosion are part of a complex system of multiple interacting processes, and both are capable of significantly affecting sediment budgets. These sediment mass movements also have the potential to significantly impact on a broad network of ecosystems health, functionality and the services they provide. To support the integrated assessment of these processes it is necessary to develop reliable modelling architectures. This paper proposes a semi-quantitative integrated methodology for a robust assessment of soil erosion rates in data poor regions affected by landslide activity. It combines heuristic, empirical and probabilistic approaches. This proposed methodology is based on the geospatial semantic array programming paradigm and has been implemented on a catchment scale methodology using GIS spatial analysis tools and GNU Octave. The integrated data-transformation model relies on a modular architecture, where the information flow among modules is constrained by semantic checks. In order to improve computational reproducibility, the geospatial data transformations implemented in ESRI ArcGis are made available in the free software GRASS GIS. The proposed modelling architecture is flexible enough for future transdisciplinary scenario-analysis to be more easily designed. In particular, the architecture might contribute as a novel component to simplify future integrated analyses of the potential impact of wildfires or vegetation types and distributions, on sediment transport from water induced landslides and erosion.

Pacifism and anti-militarism in Western Europe, 1918–1939 As the consequence of the events of 1914–1918, the pacifism was on the rise in Western Europe. Societies of England, France and Germany as well as other Western European countries, set themselves the goal of preventing another war from breaking out. International congresses and conventions were organized. They were attended by peace advocates representing various social and political views, which made cooperation difficult. These meetings did not prevent the Spanish Civil War, the aggression against Abyssinia and the outbreak of World War II. In addition to moderate pacifists, Western Europe was also home to radical anti-militarists who believed that way to the world peace led through the abolition of military service. The pacifists in Britain and France were satisfied with their politicians’ submissiveness and indecision toward Hitler during the 1930s. Pacifism and radical anti-militarism also fitted perfectly into the plans of the Comintern. With its help, the USSR weakened the military potential of Western Europe.

The new borders of Hungary in 1920 cut cities and agglomerations inducing their fallback, but the new situation favoured the creation of new functional centers. The closed boundaries after World War II resulted the development of spatial structures inside the national borders. At the same time, in Western Europe border urban areas organic development started, and they shaped cross-border agglomerations. The soundest example is the French-Belgian Lille cross-border metropolis. After the political changes, the cross-border cooperation based on real common socio-economic interest has become possible in Hungary. This processus is encouraged by the EU through its regional (Interreg, Espon) and urban (Urban, Urbact) programs. The analysis of cross-border agglomerations may be one of the axes of the Hungarian regional researches in the near future.
