Are we expecting too much from the private sector in flood adaptation? Scenario-based field experiments with small- and medium-sized firms in Ho Chi Minh City, Vietnam
; ; (Climatic Change, 2020-10-23)
Adaptive governance approaches emphasize the crucial role of the private sector in enabling climate change adaptation. Yet, the participation of local firms is still lacking, and little is known about the conditions ... -
Arsenic release from a natural rock under near-natural oxidizing conditions
; Chen-Braucher, D.; Schlothauer, Th. (Engineering in life sciences, 2008)
The solubilization of arsenic (As) from an ore material (native Arsenic [As, trig.] with Lollingite [FeAs2, rh.]) was characterized in leaching tests lasting for ≤ 99 days. The experiments were performed with materials of ... -

As above, so below? Effects of fungicides on microbial organic matter decomposition are stronger in the hyporheic than in the benthic zone
; ; ; ; ; ; ; (Limnology and Oceanography, 2021-11-16)
Microbial organic matter decomposition is a critical ecosystem function, which can be negatively affected by chemicals. Although the majority of organic matter is stored in sediments, the impact of chemicals has exclusively ... -
Ascomycete fungi on dimension stone of the “Burg Gleichen”, Thuringia
(Environmental Earth Sciences, 2011)In the present study, the diversity of ascomycete fungi was investigated on two wall areas of the “Burg Gleichen”, Thuringia (Germany), made of various types of sandstones, travertine and Grenzdolomit. From a W-exposed, ... -
Ascription of the differences between Germany and Uganda’s Land Use, Land-Use Change, and Forestry sector greenhouse gas methodologies for inventory improvement
; ; ; ; ; ; (Mitigation and Adaptation Strategies for Global Change, 2021-06-29)
Germany, as an Annex I Party is expected to prepare and submit annual Greenhouse Gas (GHG) Inventories of emissions and removals, including Land Use, Land-Use Change, and Forestry (LULUCF) sector. Uganda, a non-Annex 1 ... -
Aspects of pelagic sedimentation in the Devonian of Western Europe
(Reading : Geological Institute, 1971)During the Devonian of the Rhenich geosyncline (sediments exposed in the Rheinisches Schiefergebirge and Harz Mountains, Central Germany) condensed pelagic limestones, locally rich in cephalopods (Cephalopodenkalk), ... -
Aspects of the magnetosphere-stellar wind interaction of close-in extrasolar planets
(Univ. Zugl.: Braunschweig, 2006)Since 1995, more than 150 extrasolar planets were detected, of which a considerable fraction orbit their host star at very close distances. Gas giants with orbital distances below 0.1 AU are called Hot Jupiters. Current ... -
Aspekte bodenphysikalischer Untersuchungen in der libyschen Wüste - Ein Beitrag zur Frage spätpleistozäner und holozäner Grundwasserbildung
(Im Selbstverlag des Institutes für Physische Geographie der Freien Universität Berlin, 1987)ZUSAMMENFASSUNG : Für den Bereich der Libyschen Wüste sind, ebenso wie für die Zentralsahara, spätpleistozäne Feuchtphasen durch geomorphologische und prähistorische Befunde nachgewiesen. Diese Feuchtphasen lassen sieh ... -

Rivers and floodplains provide many regulating, provisioning and cultural ecosystem services (ES) such as flood risk regulation, crop production or recreation. Intensive use of resources such as hydropower production, ... -
Assessing Precipitation Over the Amazon Basin as Simulated by a Storm‐Resolving Model
; (Journal of Geophysical Research: Atmospheres, 2023-02-11)
In this study, we investigate whether a better representation of precipitation in the Amazon basin arises through an explicit representation of convection and whether it is related to the representation of organized systems. ... -
Assessing PS-InSAR ground motion data toward stability monitoring of coastal flood protection dikes
; ; (2023)
Sea level rise caused by climate change represents a challenge to coastal flood protection measures, particularly in regions such as the federal state of Schleswig-Holstein. Large parts along the North Sea coast are protected ... -
