Adaptations to climate change

Adaptations to climate change in the agriculture can contribute to reduced effects of climate change on water quality. By increased and more intense precipitation and warmer temperatures, the pressure on water bodies will increase regarding both altered water discharge and increased risk for eutrofication and loss of pesticides. The risk of soil loss and reduced soil quality through erosion and soil compaction will also increase with climate change.

Climate scenarios for Norway predict an increase in temperature, a longer growing season and more precipitation in most parts of the country (Hanssen- Bauer et al., 2015). More precipitation will likely have a negative effect on water quality because of the increased fluxes of nutrients like phosphorus (P) and nitrogen (N) into rivers and lakes. (Deelstra et al, 2011). Higher water temperatures are favorable to cyanobacteria, which could grow faster and create toxic waters. Even today, Norway experiences large problems related to heavy precipitation; for instance flooding, erosion, nutrient loss and damage to infrastructure. If precipitation continues to increase, the need for more or more effective mitigation measures in agriculture would become necessary.
