Key policy issues
- How will the increasing use of fertilisers affect terrestrial and marine ecosystems, with possible consequences for human health?
- To what extent can the negative impacts be reduced by more efficient nutrient management and wastewater treatment, while retaining the positive effects on food production and land productivity?
Introduction
"model component" is not in the list (driver component, pressure component, interaction component, state component, impact component, response component) of allowed values for the "FrameworkElementType" property.
