Internationale Kontrolle lokaler Verwaltung in einer Konfliktregion. Das Experiment „Freie Stadt Danzig“ (1920-1939)

The Free City of Danzig was founded by the Allies after World War One to settle the conflict between Poles and Germans as to which territory the town belonged. The League of Nations was designated to be the guarantor of its status. British and American experts and policy advisors saw it as an experiment on the way to new forms of statehood, by means of which nationalism as the founding principle of territorial entities could be overcome. However, the „Free City“ status was rejected by both the city’s inhabitants and German and Polish government agencies, with the result that the League and its local representative, the High Commissioner, were constantly confronted with difficulties in the interpretation of the international treaties and conventions relating to Danzig. In addition, hardly anyone in Danzig, Germany or Poland was interested in the economic and financial situation of the Free City, but were more interested in winning political battles than in the well-being of the city and its inhabitants. As a result, the situation in Danzig became more and more hopeless. The city became increasingly dependent on (illegal) German subsidies, while the High Commissioners generally cared more about their own prestige and that of their home countries than about the interests of the League of Nations. But as no political means of modifying the city’s status had been provided for, nothing changed formally in Danzig until Germany started the Second World War and annexed the city in September 1939. In retrospect, the international control of local government could not contribute to a long-term solution for Danzig. It merely postponed its violent solution for twenty years.

Biographien und Netzwerke im Kaffeehandel zwischen Deutschland und Zentralamerika, 1920-1959

Kaffee ist nicht nur ein beliebtes Getränk, sondern vernetzte auch unterschiedliche Welten: Der Kaffeehandel band Hamburg und Bremen in transnationale Netzwerke ein, die sich zwischen Europa und Lateinamerika erstreckten. Zentralamerika war für den globalen Kaffeehandel wichtig, weil die Region als erste die „nasse“ Form der Aufbereitung einführte. Die hohe Qualität dieser „gewaschenen“ Kaffees machte sie auf dem Weltmarkt begehrt. Deutsche Einwanderer prägten die Handelsverbindungen zwischen den zentralamerikanischen Kaffee-Anbauregionen und den norddeutschen Hafenstädten: Sie gründeten Exportfirmen, erwarben Kaffeeplantagen und beteiligten sich an der Vorfinanzierung der Ernten. Christiane Berth analysiert Biografien und Netzwerke deutscher Kaffee-Akteure in Guatemala, Costa Rica und Chiapas. Dabei zeigt sie, wie deren Handelsnetzwerke durch wirtschaftliche Krisen und neue außenpolitische Konstellationen brüchig wurden, im Nationalsozialismus unter Druck gerieten und während des Zweiten Weltkrieges zerbrachen. Trotzdem blieben auch in der Nachkriegszeit Handelsbeziehungen zwischen Nationalstaaten, Netzwerke in der Kaffeebranche und Biografien der Kaffee-Akteure eng miteinander verknüpft.

Pollen and charcoal in lake sediments compared with historically documented forest fires in southern Switzerland since AD 1920

Charcoal in unlaminated sediments dated by 210Pb was analysed by the pollen-slide and thin-section methods. The results were compared with the number and area of forest fires on different spatial scales in the area around Lago di Origlio as listed in the wildfire database of southern Switzerland since AD 1920. The influx of the number of charcoal particles > 75 µm2 in pollen slides correlates well with the number of annual forest fires recorded within a distance of 20-50 km from the coring site. Hence a size-class distinction or an area measurement by image analysis may not be absolutely necessary for the reconstruction of regional fire history. A regression equation was computed and tested against an independent data set. Its use makes it possible to estimate the charcoal area influx (or concentration) from the particle number influx (or concentration). Local fires within a radius of 2 km around the coring site correlate well with the area influx of charcoal particles estimated by the thin-section method measuring the area of charcoal particles larger than 20 000 µm2 or longer than 50 µm. Pollen percentages and influx values suggest that intensive agriculture and Castanea sativa cultivation were reduced 30-40 years ago, followed by an increase of forest area and a development to more natural woodlands. The traditional Castanea sativa cultivation was characterized by a complete use of the biomass produced, so abandonment of chestnut led to an increasing accumulation of dead biomass, thereby raising the fire risk. On the other hand, the pollen record of the regional vegetation does not show any clear response to the increase of fire frequency during the last three decades in this area.

Tuberculosis Mortality and Living Conditions in Bern, Switzerland, 1856-1950.

BACKGROUND Tuberculosis (TB) is a poverty-related disease that is associated with poor living conditions. We studied TB mortality and living conditions in Bern between 1856 and 1950. METHODS We analysed cause-specific mortality based on mortality registers certified by autopsies, and public health reports 1856 to 1950 from the city council of Bern. RESULTS TB mortality was higher in the Black Quarter (550 per 100,000) and in the city centre (327 per 100,000), compared to the outskirts (209 per 100,000 in 1911-1915). TB mortality correlated positively with the number of persons per room (r = 0.69, p = 0.026), the percentage of rooms without sunlight (r = 0.72, p = 0.020), and negatively with the number of windows per apartment (r = -0.79, p = 0.007). TB mortality decreased 10-fold from 330 per 100,000 in 1856 to 33 per 100,000 in 1950, as housing conditions improved, indoor crowding decreased, and open-air schools, sanatoria, systematic tuberculin skin testing of school children and chest radiography screening were introduced. CONCLUSIONS Improved living conditions and public health measures may have contributed to the massive decline of the TB epidemic in the city of Bern even before effective antibiotic treatment became finally available in the 1950s.
