  • Example: Overuse of phosphorus-rich fertilizers leading to excessive plant growth and reduced soil quality.

8. Freshwater Eutrophication:

  • What it measures: Nutrient releases causing excessive plant growth in freshwater bodies.

  • Relevance to food: Runoff from agricultural lands, rich in nitrogen and phosphorus, can be a significant contributor.

  • Example: Algal blooms in freshwater bodies due to nutrient-rich runoff from farms.

9. Marine Eutrophication:

  • What it measures: Nutrient releases causing excessive plant growth in marine environments.

  • Relevance to food: Agricultural runoff and wastewater discharge can contribute to this impact.

  • Example: Dead zones in coastal areas due to excessive nutrient runoff.

10. Land Use:

  • What it measures: Impact on biodiversity due to land occupation or transformation.

  • Relevance to food: Conversion of forests or natural habitats to farmland affects biodiversity.

  • Example: Clearing of rainforests for palm oil or soybean cultivation.

11. Ecotoxicity for Freshwater Aquatic Ecosystems:

  • What it measures: Potential harm to freshwater ecosystems from released substances.

  • Relevance to food: Pesticides, herbicides, and other farm chemicals can harm non-target species.

  • Example: Runoff carrying pesticides affecting aquatic life in nearby streams.

12. Depletion of Water Resources:

  • What it measures: Over-extraction of freshwater resources.

  • Relevance to food: Agriculture is a major water consumer, making sustainable water management crucial.

  • Example: Over-irrigation in arid regions leading to depletion of local aquifers.

13. Depletion of Energy Resources:

  • What it measures: Over-extraction of energy resources like coal, oil, and gas.

  • Relevance to food: Energy-intensive agricultural practices and food processing can contribute.

  • Example: High energy use in greenhouses for off-season crop production.

14. Depletion of Mineral Resources:

  • What it measures: Over-extraction of minerals.

  • Relevance to food: Mining for fertilizers or other agricultural inputs can contribute.
