  1. 1. Climatesmart Agriculture and soil- carbon sequestration Marja-Liisa Tapio-Bistrm, FAO May 2012
  2. 2. Contents Challenges Climate smart agriculture Mitigation thorough land management Conclusions FAO and climate change
  3. 3. Two Goals of Our Time1. Achieving Food Security 1 billion hungry Food production to increase 70% by 2050 Adaptation to Climate Change critical1. Avoiding Dangerous Climate Change 2 degree goal requires major emission cuts Agriculture and Land use = 30% of emissions.. ..and needs to be part of the solution
  4. 4. Climate Change & Agriculture GHG emissionsSources of GHG emissions by sector (IPCC 2007)
  5. 5. A Sustainable Development landscape+Human rights,UNFCCCCBDWSFSHealth, Trade, GLOBAL CarbonSpeciesCalories Education, ..... OBJECTIVESNational ->InternationalNational ->Local ClimateBiodiversity Food Security LOCALClimatesmart AgricultureREALITIES
  6. 6. Climate-Smart AgricultureAgriculture that sustainably: increases productivity and income increases resilience of livelihoods andecosystems (adaptation) reduces/removes GHG emissionsAND enhances achievement of national foodsecurity and development goals ADRESSES MULTIPLE OBJECTIVES!
  7. 7. Indicative relevanceParameter IncreasedResilience / Mitigatonproductivity AdaptationIncome from products and services Carbon stock in the landscape Energy use / GHG emissions
  8. 8. Agricultural sources and sinks of greenhouse gases IPCC 2007
  9. 9. Climate Change & AgricultureMitigationMitigation options in the land use sectorMitigation potentials: Forestry 5.4 Gt CO2/yrAgriculture: 5.5-6 Gt CO2e/yr86 % in developing countries (2) Avoiding or(3) Removing(1) Reducingdisplacingemissions andemissions emissions creating sinks
  10. 10. Mitigation options Restoration of cultivated organic soils/peatlands Cropland management Rangeland management Restoration of degraded lands Agro-forestry Avoided deforestation -sustainable intensification onexisting agricultural lands Increase/maintain landscape-scale C stocks - add trees
  11. 11. Peatlands and organic soils 3% of the land area 30 % soil carbon 25 % of CO2 emissions from land areasfrom drained pealtands (0.3% of landarea) Secure undrained peatlands to preventemissions Rewet drained peatlands to reduceemissions Adapt management of peatlands thatcannot be rewetted
  12. 12. Land management and mitigation -C loss due to poor agricultural practicesDeforestationIntensive tillage; erosion CO2 Woody encroachmentSoil organic matter Overgrazing
  13. 13. Land management and mitigation-Adding C to the system Cover cropsSilvo-pastoral systemsCO2Sowing legumes/improved species Soil organic Improved rotationsmatter
  14. 14. Land management and mitigation-Avoid emissions in land management Reduce forage off-take Arrest erosionCO2 Leave crop residuesSoil organicNo-tillagematter
  15. 15. Overview/conclusions Land management contributes massively toglobal greenhouse gas emissions Change in land management can reduceemissions and can sequester C in soils Nobody farms to mitigate climate change Sustainable land management is a win-winresponse to climate change and food securitychallenges Land tenure and governance situations areseverely limiting the possibilities
  16. 16. FAO and Climate Change challenges Integrated across Programme of Work Involves all Departments and Offices Some key programmesClimate-smart Agriculture
