Households at Risk: Integrated Assessment of Drought Hazard and Social Vulnerability in the Cuvelai-Basin of Angola and Namibia
(2018-11-22)
Droughts are phenomena that occur worldwide, in humid and arid environments as well as in the Global North and the Global South. They are considered as slow onset hazards that affect more people than any other natural ...
A Landsat-based analysis of tropical forest dynamics in the Central Ecuadorian Amazon: Patterns and causes of deforestation and reforestation
(2018-12-20)
Tropical deforestation constitutes a major threat to the Amazon rainforest. Monitoring forest dynamics is therefore necessary for sustainable management of forest resources in this region. However, cloudiness results in ...
Untersuchungen zur Bodenerosion auf der Kanarischen Insel Hierro: Ursachen, Entwicklung und Auswirkungen auf Vegetation und Landnutzung
(1987)
Die Untersuchungen der vorliegenden Arbeit führen von einer Bodenklassifikation über die genaue Erfassung und den statistischen Vergleich repräsentativer Standorte schließlich zu der Herausarbeitung von vier unterschiedlichen ...
An Integrated Remote Sensing and Urban Growth Model Approach to Curb Slum Formation in Lagos Megacity
(2019-04-05)
Rapid urbanization with limited development has led to slum proliferation in many sub-Saharan African cities. Slums are recognized as a menace to planned cities, as they do not conform to planning standards, thus the need ...
Model-based Source Partitioning of Eddy Covariance Flux Measurements
(2019-05-03)
Terrestrial ecosystems constantly exchange momentum, energy, and mass (e.g., water vapor, CO2) with the atmosphere above. This exchange is commonly measured with a micrometeorological technique, the eddy covariance ...
Evaluating the Contribution of Remote Sensing Data Products for Regional Simulations of Hydrological Processes in West Africa using a Multi-Model Ensemble
(2019-05-02)
Water is a crucial resource for human health, agricultural production and economic development. This holds especially true in West Africa, where large parts of the population work as self-sustaining farmers. Accurate ......
Schrumpfungsprozesse als zentrale Herausforderung für die zukünftige Entwicklung von Kommunen im Rahmen der rheinland-pfälzischen Dorferneuerung: dargestellt am Fallbeispiel des Landkreises Mayen-Koblenz
(2021-03-23)
Die Herausforderungen und bislang zumeist unbekannten Änderungserfordernisse an bestehende Strukturen, welche sich aus den ablaufenden Prozessen des demographischen Wandels ergeben, sind die momentan gewichtigsten, welche ...
Addis Ababa Airport zwischen Globalisierung und Fragmentierung: Ein Hub in Raum und Zeit
(2019-03-15)
Diese Forschungsarbeit untersucht den Flughafen von Äthiopiens Kapitale Addis Abeba als einen Ort, an dem verschiedenartige, teils ambivalente Entwicklungen zusammen¬treffen. Der Bole International Airport steht als Beispiel ...
Multi-scale modeling of water resources in a tropical inland valley and a tropical floodplain catchment in East Africa
(2019-02-12)
This study investigated the dynamics of hydrological processes at the wetland-catchment scale through field scale-based analysis, point scale modeling using Hydrus-1D model along a floodplain transect in Tanzania and ...
Impact Assessment of Land-Use Change and Agricultural Treatments on Greenhouse Gas Emissions from Wetlands of Uganda and Tanzania
(2020-02-04)
Wetlands play an important role in global climate regulation as they represent a great global carbon sink. Moreover, wetlands provide optimal conditions for food production and support the livelihoods of many people in ...
