Interlinkages of Land Degradation, Marginality and Land Use Cover Change in Kenya: Development of an interdisciplinary framework using remote sensing and GIS
(2015-12-01)
Land degradation (LD) is a global problem affecting and being affected by socio-ecological systems. In this thesis the interlinkages of LD, marginality and land use cover change (LUCC) in Kenya based on remote sensing and ...
The role of soil heterogeneity on field scale evapotranspiration: 3D integrative modelling and upscaling of root water uptake
(2015-09-24)
Background and Motivation: Hydrological models mainly rely on empirical functions to describe root water uptake. However, in case of water limitation due to either scarce or heterogeneously distributed soil water, plants ......
