Land degradation

When you are working with soils, you have to face many challenges. How can we prevent dessication which makes it hard to grow food and other useful plants? How to prevent drought and salination to cause significant damage and harm to local economy and other human crises? How can we prevent this continuous decline of soil fertility, productivity and cultural and recreational values which has many negative effects, especially for vulnerable ecosystems?

Projects

  • Hydrological effects of revegetation on hillsides

    Country - South Africa
    Carried out by - 
    Marjan Sommeijer

    Background research

    • The Baviaanskloof is an extremely arid and heavily degraded area as the result of farming. 
    • This means it is hard for the soil to retain the little rainwater that falls, causing serious erosion. 
    • To counter this, it was decided to (re)plant spekboom trees. This tree originates from the region, and does not need much water. 
    • The idea is that because of the spekboom trees, the soil, and most importantly the groundwater, will be better retained and for longer.

    Services provided

    • To measure the effect, Marjan used the Eijkelkamp Soil & Water rainfall simulator
    • “The rainfall simulator is a really great tool that makes it relatively easy to show the effect of vegetation on interception and infiltration.”

    Results of the research

    The research showed that (re)planting spekboom trees does indeed have a substantial effect on water retention.

  • Insight into Municipality of Zutphen’s groundwater situation

    Client - Municipality of Zutphen (the Netherlands)

    Background

    • Sound knowledge of groundwater levels, flows and fluctuations within the urban area is required for the Municipality to fulfil its duty of care regarding groundwater
    • The measuring system will also be used to provide citizens or developers with information regarding groundwater levels
    • The Municipality previously obtained this information from the environment department’s groundwater research during soil decontamination or from the Provinceof Gelderland, but these were all snapshots
    • TheMunicipality ofZutphen also wanted more insight into how the water levels from theIJssel river influence groundwater levels

    Services provided

    • Eijkelkamp Soil & Water installed a total 44 Diver water level loggers together with telemetry
    • Groundwater data are combined automatically in the existing regional control station
    • Eijkelkamp Soil & Water will manage the network for 10 years and also carry out maintenance

  • Groot Salland Water Board goes digital

    Client - Groot Salland Water Board (The Netherlands)

    Background 

    • In the past, groundwater levels were measured and recorded manually each month on the 14th and 28th.
    • 'Where we previously needed 15 people to manage the measuring system, we now only need 2.'
    • 'Digital measurements provide more and improved data and this is needed for good water level control'

  • Groundwater research in Spanish conservation area

    Client - Acuamed and the Spanish Government (Spain)
    Period - 2011

    Background

    • The 204-hectare conservation area near Sebes has seen a strikingly high death rate amongst certain floodplain forest plants 
    • A reduction in the fluctuation of the water levels is thought to be the major cause of this loss of plant life 
    • Flooding also raises the groundwater level so that the soil is insufficiently washed and becomes increasingly saline
