  1. Dryland Soil Carbon Sequestration in Central Asia and Beyond CAREC Project Concept

  2. Agenda Introduction Carbon Sequestration Potential Sustainable Agricultural Practices Emission Trading Scheme Core Activities Budget Indication

  3. Introduction • Size of Central Asia: 4 mio km² • Dryland in CA: 3,7 mio km² → 92,5 % • Carbon Balance of Dryland Soil on Average: 50 t/ha

  4. Carbon Sequestration Potential • CA soil has lost 3-4% of its Soil Organic Carbon (SOC) → 725 mio. t CO2 • Reason: Conversion of „virgin land“ and excessive monoculture • Other sources, not included in estimation: • Soil Salinity • Overgrazing • Wind/Water erosion → Future threat for food security, health and main income source of rural population Source: http://www.undp-adaptation.org/projects/websites/images/stories/Projects/Kazakhstan/Lepsy/2002_0314_181305AA.JPG Source: http://www.undp-adaptation.org/projects/websites/images/stories/Projects/Kazakhstan/Sauxal/DSC04100.JPG Source: http://www.undp-adaptation.org/projects/websites/images/stories/Projects/Kazakhstan/Akmola/Autumn%20water%20supply%20of%20the%20degraded%20pastures.JPG

  5. Sustainable Management Practices (SMP) • Conservation Tilling, No-Till Techniques • Cover Crops (especially legumes) • Crop Rotation • Water Efficiency • Rotational Grazing • Enhanced Pasture Plants → Soil Organic Matter Increase: • Enhanced Soil Fertility • Combatting further Erosion • Carbon Sequestration Source: http://de.wikipedia.org/w/index.php?title=Datei:Medicago_sativa0.jpg&filetimestamp=20041028153352 Source: http://www.unwnrd.org/_img/for_projects/no-till/no_till_corn08.jpg Source: http://www.noble.org/ag/Forage/GivePasturesRest/pasturesLR.jpg

  6. Emission Trading • Benefits from Emission Trading Scheme could provide necessary financial incentive to adopt SMPs • Currently, Carbon Sequestration not eligible for CDM funding → Problems in measurement & monitoring (M&M) Goal Enhanced soil quality in Central Asia due to widespread use of sustainable land management practice, backed up by a system for measuring and monitoring carbon sequestration in order to profit from emission trading.

  7. Core Activities • 1. Phase: Scientific Workshop Series → Synthesized knowledge on CS in dryland, to be distributed within scientific/political community 2. Phase: 3 – 5 Pilot Projects → Knowledge (products) on SMP → Assessment of M&M systems and first evaluation of CS potential 3. Phase: Projection of CS potential in CA → Advocacy of integration into Emission Trading

  8. Thank you for your attention
