  1. Piloting Pyrolytic Cookstoves and Sustainable Biochar Soil Enrichment in Northern Vietnam UplandsProject No. 3 – V – 048

  2. Objective Overall objective: To address the rural energy problems and soil degradation, and contribute to national policies on poverty reduction, deforestation and rural development Specific objective: To test biochar stove-cum-soil enrichment technology and prepare for up-scaling its application.

  3. Partners CARE International in Vietnam Soil and Fertiliser Research Institute (SFRI) Population, Environment and Development Centre (PED) Provincial Women Union in 2 provinces Agriculture and Forestry Extension in 2 provinces Advisory group: Professors from Cornell and New South Wale Universities

  4. Project sites 2 Communes in Dinh Hoa district - Thai Nguyen province Beneficiaries: 300 hhs – Tay, Nung, San Chi 1 commune in Ba Thuoc district – Thanh Hoa province. Beneficiaries: 150 hhs – Muong

  5. Outputs Households apply biochar stoves (400 HHs), use of fuelwood reduces 80%, and biomass 60% Testing of biochar stoves Study household application of biochar for soil enrichment Replication and Up-scaling assessed and dissemination plan developed

  6. Activities and the results Output 1: Households apply biochar stoves Conducted baseline, agriculture production and gender surveys

  7. Biochar Produced From Open Field Burning and Open fires Burning of most of the straw occurs in some fields and in others there is none or very little Many household soak their wood and bamboo in a nutrient mineral rich pond before burning in a fire. The mineral matter that soaks into the biomass slows the combustion process and makes a large amount of biochar and ash. Soil samples from burnt and unburnt areas Wood is aged underwater held down by bamboo

  8. The Context; Farmers Have Been Using Biochar for over 40 years Rice straw biochar from the field with NPK fertiliser around the spring onion seedlings

  9. Activities and the results • Output 1: Cont. • Select stove types - Redesign and retest • Imported 2 stove sample from india (TLUD; Sampada) • Produced and distributed 60 biochar stoves in March 12 • Produced 100 improved stoves and distributed in Thai Nguyen – May 2012 • Produced 240 stoves in June.

  10. Activities and the results • Output 1: Cont. • Train households in use of cook stove and biochar • 3 courses on stoves using demonstration in 3 communes • 6 courses on biochar making and using in 6 villages

  11. Activities and the results Output 2: Testing of biochar stoves Import TLUD and Sampada stoves samples from India Conducted the test in the lab with participation of advisory member from NSW.

  12. Activities and the results • Output 2: Testing of biochar stoves • Survey household experiences with biocharstoves • Tested with group of farmers and individual at households • Conducted home based assessment of stove users satisfactoriness • Analyse other effects of biochar stoves • Conducted WBT and CCT tests with farmers • Gasses emission analysis

  13. Activities and the results Field work

  14. Activities and the results 6 Kilns for producing biochar were made for 6 villages

  15. Activities and the results Kilns have been used for making biochar for all rice trials in the project sites

  16. Activities and the results Output 3: Study application of biochar Conducted the surveys on soil types crop system, select field for trials Set up 12 rice trials in Thai Nguyen and ThanhHoa Set up 22 garden vegetable trials in both provinces Organized 2 field workshops for rice trial in 2 provinces Set up 8 rice trials in 2 provinces

  17. Key Findings: Biochar application and its effect

  18. Women Making Biochar and Biochar Composts For Field Trials

  19. Activities and the results

  20. Activities and the results • Output 4: Assessment of up-scaling • Study local manufacturing • Many visits to local workshops Ha Tay, BacNinh, HaiPhong prov. • Contracted them for spare parts • Support local stove production • Financial support have been given to workshop in Thai Nguyen for manufacturing stoves. Produced and distributed 160 stoves to households. • Continue produce 240 stoves, 30 fix stoves

  21. Activities and the results • Output 4: Assessment of up-scaling • Engage cooperation partner staff in learning activities • Organized field workshops at 2 communes and technical sharing WS at district • Dissemination information in VTV2, • Presentation at WS in US Apr 12, • Published articles in IBI journal. • Presentation at IBI’s WS in China Sep 12 • Received visits from ADB, Global Cookstove Alliance
