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 ...
Planning and Implementation of the Dyke Systems in the Mekong Delta, Vietnam
(2011-04-05)
Floods are a dangerous threat and an implicit risk for farming communities in rural floodplains of the Mekong Delta (MD). The Vietnamese government decided the dyke system construction to control floods and ensure safety ...
The Influence of Land-use Activities on Nutrient Inputs into Upland Catchment Streams, Ghana
(2009-10-08)
In Ghana, increasing agricultural productivity is seen as an essential component of most development programs. The main objective of this study was to assess the implications of increased land-use activities on in-stream ...
Growing lake with growing problems: integrated hydrogeological investigation on Lake Beseka, Ethiopia
(2009-02-03)
The complex tectonic and volcanic processes in the Ethiopian rift valley have resulted in the formation of volcano-tectonic structural depressions that became sites for many rift valley lakes. Lake Beseka is one of the ...
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 ...
Implementation of the local land-use and land-cover change model CLUE-s for Central Benin by using socio-economic and remote sensing data
(2007)
Within the last decades wide areas in West Africa are subjected to serious land-use and land-cover changes (LUCC). The detection of the changes, the understanding of the underlying processes as well as modeling of scenarios ...
Estimation of groundwater recharge in the context of future climate change in the White Volta River Basin, West Africa
(2008)
The White Volta River Basin is one of the major sub-basins of the Volta River Basin of West Africa. It covers about 106,000 km2, and the major riparian countries are Burkina Faso and Ghana. The basin has enough ...
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 ...
