Calculating the impact of climate change and water management on terrestrial vegetation in nature areas

WaterVision Nature

WaterVision Nature (WWN) is a freely-available tool to calculate the impact of climate change and water management on terrestrial vegetation in nature areas.

Below, you’ll find the links for the installation and user manuals. If you’re enthusiastic about the application of WWN, please register at the Helpdesk to receive WWN updates and other news about the tool.

What can WaterVision Nature do?

The vegetation in nature areas makes specific demands on water management, particularly with regard to groundwater levels. Existing assessment systems however do not take the consequences of climate change into account. That is why a system has now been developed that does accomplish this: WaterVision Nature (WWN). This tool can be used to:

  1. test water management against existing vegetation objectives;
  2. assess whether vegetation objectives are achievable under other climate conditions;
  3. identify new sites suitable for nature development;
  4. optimise water management for the benefit of nature.

The tool calculates very quickly and generates results in the shape of clear maps and tables. Figure 1, for instance, shows the results of a search for potential sites for nature development.

Why a new system?

Changes in climate and water management have an impact on vegetation objectives, but existing knowledge of water and vegetation is dated and therefore not useful for climate projections. In collaboration with STOWA, KWR has developed the WaterVision Nature tool, which incorporates the maximum number possible of the processes affected by climate change (Figure 2).

Development

The first model version was released in September 2018. For the further development, STOWA has formed a consortium including the national government, provinces, Water Authorities, water utilities and the implementing research institutes KWR and WENR.

WaterVision Agriculture

Besides WaterVision Nature, the above parties have also developed WaterVision Agriculture (WWL). This tool determines the effects of changes in hydrological conditions on agricultural production. Click here for more information about WWL..
