  1. 1. GHG emission in agriculture in Vietnam Assessing Low Carbon Poten8als for the Viet Nam Green Growth Strategy Mai Van Trinh, Agricultural team leader Ins8tute for Agricultural Environment (IAE)
  2. 2. GHG emission in Vietnam The first (1994) and the second (2000) GHG inventories results from agricultural sector (thousand tonnes years-1) Greenhouse gases Total Subsector CH4 N2O CO NOx In CO2 equivalent % 1994* Enteric Fermentation 336.6 0.001 7070 13.5 Manure Management 129.0 2710 5.2 Rice Cultivation 1,559.7 32750 62.4 Agricultural Soil 26.0 8060 15.4 Prescribed Burning of Savannas 15.9 0.2 417.5 7.1 400 0.7 Field Burning of Agricultural Residues 51.7 1.2 1,086.1 43.2 1460 2.8 Total 1994 2,092.9 27.4 1,503.6 50.3 52450 100 2000** Enteric Fermentation 368.12 7,730.54 11.9 Manure Management 164.16 3,447.30 5.3 Rice Cultivation 1,782.37 37,429.77 57.5 Agricultural Soil 45.87 14,219.70 21.8 Prescribed Burning of Savannas 9.97 1.23 261.71 4.46 590.67 0.9 Field Burning of Agricultural Residues 59.13 1.39 1,214.68 50.28 1672.63 2.6 Total 2000 2,383.75 48.49 1,476.39 54.74 65,090.61 100 Sources: * VINC (2003); ** VNSNC (2010)
  3. 3. Viet Nam Green Growth Strategy (9/2012) 1. Reduce the intensity of green house gas emissions and promote the use of clean and renewable energies Reduce the intensity of GHG emissions by 8-10% compared to 2010, 10% - 20% for energy sector o Greening production : Key indicators: value of high-tech and green-tech products will make a share of 42-45% in GDP o Greening lifestyle and promoting sustainable consumption Key indicators: waste water meet regulated standards, low grade cities and craft villages environment quality improved 40-60% è National Action Plan on Green Growth in Vietnam March 2014
  4. 4. GHG reduc=on plan by Ministry of Agriculture (20%) • Crop production: SRI, 3R3G, 1M5R, residue reuse o Livestock: feed dosage change; MUB, biogas, compost o Fishery/aquaculture: change in fishing vessel (more energy efficient engines) , technical-improvement; aquaculture feed supply and aqua-cultural practice; o Irrigation: saving energy, improved capacity o Rural environmental management: waste management; fuel change, saving energy, cleaner production
  5. 5. Methodology Sources: Simon Eggleston
  6. 6. Methodology for GHG quan8fying Method to calculate GHG emission • GHG emission from Enteric fermenta8on calculated by IPCC1996 (Tear1) • GHG emission from Manure management calculated by IPCC1996 (Tear 1) • GHG emission from prescribed burning of savannas was calculated by IPCC1996 (Tear 1) • GHG emission from field burning of agricultural residues calculated by IPCC1996 (Tear 1) • GHG emission from rice cul8va8on and agricultural soils were calculated by GIS based DNDC with overlaying of Land use map in 2005, soil map and provincial climate data (2010, scenario of 2015, 2020, 2025 and 2030 following climate change scenario of MONRE, 2011 – Tear 2) MACC curve is developed based on an “expert based approach”
  7. 7. Methodology Total GHG emission from crop produc8on Province Meteo sta=ons 63 provincex11 soilsx5 climate yearsx6 measures = 20,790 runs Land use map Soil map
  8. 8. Methodology -­‐ mi=ga=on CLIMATE data Outputs (BAU) • Crop yield • CH4 • N2O • CO2 Calibrated Build DNDC DNDC Observed yield, CH4, N2O, CO2 from IAE and references Outputs (Ac8on) • Crop yield • CH4 • N2O • CO2 Ac8ons Ac8on scenario DNDC Outputs (Mi8ga8on) • Crop yield • CH4 • N2O • CO2 Ac8ons + mi8ga8on + Mi8ga8on scenario DNDC Land use map LMU map Soil map
