Water for food means finding ways for efficient use of the available water resources. One of the innovative technologies the Netherlands is experimenting with is decentralized water storage. Examples are recharge of drainwater from agricultural land and retention of fresh drainwater in a salt groundwater environment.
Spaarwater is a project for decentralized water storage in the north of the Netherlands. The principle purpose of the project is expansion of the freshwater availability with efficient use of the available water at site. By combining groundwater infiltration with subsurface drip irrigation the highest possible efficiency of the use of local precipitation is realised. The north of the Netherlands is of high agricultural value. Due to climate change this region, like the rest of the country, will suffer from fresh water shortages in the summer, with crop damage as a result. Combination of innovative techniques like in the project Spaarwater contributes to robust and efficient agricultural activities.
- Recharge of drainwater from agricultural land
- Retention of fresh drainwater in a salt groundwater environment
- Self-sustainability for fresh water
- Enough fresh water originating from local sources
- Avoiding drought damage
- Avoiding salt damage
- Efficient irrigation with the use of drip lines
- Efficient use of fertilizer with the use of fertigation
- Extra yield of approximate ± 1 – 17% due to drip irrigation
A consortium of Dutch partners contribute to the Spaarwater project. Project leader is Acacia Institute together with executive partners Acacia Water, DLVplant, Broere Beregening, BE-de-Lier, Netafim, Vrije Universiteit and Han de Kreuk.
