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
