Presentation Transcript

  1. Soil ecosystem services their value and use in promoting sustainable farming Katarina Hedlund Lund university SOIL SERVICE project (FP7)

  2. Agriculture and soil threats Intensification of agriculture Decline in: Lead to: soil carbon soil erosion biological activity soil compaction soil biodiversity reduced resistance to pests reduced nutrient provisioning

  3. Soil is a natural capital Soil biodiversity Actions and inter-actions among soil organisms feeding digging burrows mycorrhiza Ecosystem services Nutrient retention Carbon storage Water retention Resistance to pests Regulation of above ground diversity Ecosystem goods Food Feed Biofuel Clean water Climate mitigation

  4. SOIL SERVICE study regions Regions for soil biodiversity and farm economy studies

  5. Soil biodiversity and agriculture soil biodiversity—correlated to ecosystem services

  6. Soil biodiversity & intensive agriculture • Reduce species diversity • Lower food chain length • Soil carbon: 10 – 0.8 %C • Soil nitrogen: 0.4 - 0.1%N • Phosphorous uptake by AM fungi: from 150 to 15 kg/ha • Reduced soil mixing: from 100 to 5 tons/ha • Reduction of soil aggregates: more than 50% Pastures to crop rotation:

  7. Value of the soil ecosystem services Value to farmers • Fertile soils • Water retention • Less erosion • Less use of • fertilizers • pesticides Value to society • Reduce eutrofication • Clean water • Carbon retention €?

  8. Agricultural production functions Farm A Farm B 0.2 % C between the treatments

  9. Economic valuation:Carbon a currency for natural capital

  10. Long term decline of soil-C in Europe

  11. Optimal use of soil C Optimal yield Optimal fertiliser use

  12. Carbon a natural capital

  13. Scenarios for predicting the future Adopted from the ACCELERATES project (Abildtrup, et al. 2006

  14. Farm profits and C change in 2035

  15. Insurance value of conserving soil-C 3 Swedish farms production risk • wheather • pest outbreaks market risk • food price volatility • increasing fertiliser prices • increasing energy prices

  16. How can we affect Soil C

  17. Soil a natural capital • Promoting soil C means increasing soil biodiversity and soil ecosystem services • sustainable agriculture • Processes are long term and farmers economy will be affected in the future • long term investments • Soil ecosystem services reduce risk • production and market risks

  18. How to invest in soil —a natural capital? What decisions can mitigate soil carbon losses? Are payments for soil carbon possible? How can we design long term policies?
