The IMAGE soil nutrient model includes a variety of options to reduce nutrient surpluses in agriculture or nutrients in wastewater, and strategies to improve resource use efficiency. Strategies that can be assessed with tools available in the nutrient model of IMAGE include those for wastewater: | |||
• Increase the access to improved sanitation, and connection to sewage systems; | |||
• Institution of wastewater treatment installations; | |||
• Substitution of synthetic fertilisers by fertilisers produced from human excreta. This option has no consequences for nutrient budgets, but reduces wastewater flows. | |||
