Research of the Soil Physics and Land Management Group
Research in the chair group Soil Physics and Land Management (SLM) addresses soil physical and hydrological processes at different temporal and spatial scales, and their central role in sustainable land and water management.
To advance understanding of the impacts of land use and management on soil physical processes and related ecosystem functions that are essential for addressing global societal challenges of water and food security, sustainable land management, and climate adaptation.
To develop and advance both fundamental and applied knowledge of soil physics and land management and the research skills of future scientists, through focussing our research on the interactions between land use and management and soil physical processes using innovative approaches that link different disciplines and engage stakeholders.
To study transport processes of water, sediment and solutes over and through soils, particularly in relation to land use and management practices and how these affect soils, groundwater, crops, vegetation and related ecosystem services and stakeholders.
Our research areas:
- Soil physics; flow and transport of water, heat, sediment and solutes
- Ecohydrology; soil-water-plant interactions
- Land use and management; factors affecting soil degradation, conservation and restoration
Significant results and highlights of the SLM research programme in recent years
1. A research field focused on the stochastic aspects of ecohydrology that affect natural and agro-ecosystems
- DESMICE (Desertification Mitigation Cost-Effectiveness), a GIS-based model to spatially assess short and long term costs and benefits of land management interventions
Event-based Open LISEM model code to simulate hydrological and soil erosion at watershed scale
- New online version of Soil-Water-Atmosphere-Plant (SWAP) model (www.swap.alterra.nl), better integrating plant and soil physical processes, and solute transport (SWAP-ORCHESTRA)
- New sediment trap to measure sand spray, enabling gathering of samples that was not previously possible
- Wireless embedded network system for real-time soil moisture sensing, facilitating easy roll out of sensors across study sites and watersheds to obtain data of high temporal and spatial resolution
- Polymer tensiometer, enabling measurement of pressure heads even in very dry soil conditions
4. Other advancements
- A multi-scale methodology to identify, prioritize, implement and evaluate soil and water conservation measures with farmers and other stakeholders, adopted by the UNCCD for further use around the globe
