Experimental and numerical studies on solute transport in unsaturated heterogeneous porous media under evaporation conditions
(2012-08-31)
Groundwater level rise, root water uptake, or evaporation induces local upward water and solute fluxes in soils, causing soil salinization and rise of contaminants to the soil surface, and influencing the migration of ...
Analysis of Water Use and Crop Allocation for the Khorezm Region in Uzbekistan Using an Integrated Hydrologic-Economic Model
(2011-04-20)
Sustainable and efficient water management is of central importance for the dominant agricultural sector and thus for the population and the environment of the Khorezm region. Khorezm is situated in the lower Amu Darya ...
Soil organic carbon pools and their spatial patterns: rapid assessment using mid-infrared spectroscopy
(2011-02-09)
Soil organic carbon (SOC) plays an important role in global C cycling. Until today, the spatial patterns of individual SOC fractions are, however, largely undiscovered as traditional methods for their determination are too ...
Spatiotemporal dynamics of stress factors in wheat analysed by multisensoral remote sensing and geostatistics
(2007)
Plant stresses, in particular fungal diseases, basically show a high variability in space and time with respect to their impact on the host. Recent ‘Precision Agriculture’ techniques allow for a spatially and temporally ...

(2005)
Die vorliegende Arbeit befaßt sich mit den methodischen Problemen, die bei der Erstellung von Unkrautverteilungskarten mit Geoinformationssystemen (GIS) auftreten können. Im Vordergrund steht dabei die Frage nach der ...
Acceptance Analysis of New Technology for Sustainable Water Management and Sanitation: A Case Study of Operating Farm Households in the Mekong Delta, Viet Nam
(2005)
Recent development in agricultural und industrial production leads to increasing pollution of the water sources in the Mekong Delta of Vietnam. According to the "Vietnam Environment Monitor 2003 - Water", no safe drinking ...
GIS-basierte Erfassung und Prognose der räumlichen Verteilung von Pflanzenkrankheiten
(2005)
Die Erforschung der räumlichen Verteilung von Pflanzenkrankheiten wurde bisher in der Phytomedizin vernachlässigt, da keine adäquaten Mittel zur Verfügung standen, um die auftretenden Phänomene analysieren und darstellen ...
Mining and small-scale farming in the Andes: Socio-environmental roots of land-use conflict
(2020-04-08)
The Peruvian Andes are one of the most important water sources for the country. Therefore, their exploitation might pose critical threats for local farming activities, national economy, and water quantity and quality. At ...
Linking slopes to the wetland: Hillslope hydrology and associated nitrate transport in a tropical valley bottom wetland
(2022-11-07)
Valley bottom wetlands are regarded as a white hope for enhancing food security in East Africa. Due to their prolonged water availability, they buffer some of the effects of climate change and further offer fertile soils ...
Health and Welfare Implications of Climate Variability: Evidence from Rural Uganda
(2022-12-20)
Uganda has been highly affected by extreme weather events and climate change in the recent years. Weather-related disasters could potentially affect health outcomes directly, or indirectly through its deleterious effects ...
