Bioenergy and Land Use Issues in Asia N. H. Ravindranath Indian Institute of Science Bangalore
2
Key Messages 1. Multiple options for land use – in the context of mitigating climate change & development Biomass power, biofuels (liquid fuel), Afforestation for C-sink, timber production for substituting aluminum, steel, etc 2. Currently Asia is not a dominant biofuel producer / consumer of biofuels (like Brazil, US, EU) 3. However, dominant energy consumers have set targets for biofuels to substitute petroleum - thus Asia will be the key regions for biofules China (15% - 2020), India (10%- 2020), Japan (30% by 2030), Malaysia/Indonesia/Thailand (10% -2020) 4.Biofuel program in India, China, Thailand etc are driven by need for Energy Security Thus need to ensure minimal GHG emissions
3
Key messages 4. Area under food production has stabilized in all the key Asian countries- unlikely to increase India, China, Thailand, Malaysia, etc Food grain needs will be met by increasing crop productivity and intensity Large extents of degraded non-crop and marginal crop lands are available for bioenergy/ biofuel crops / Carbon sink 5. Biodiesel crops such as Jatropha, oil Palm and tree based crops are key biofuel crops are critical in Asian countries India, China, Malaysia, Indonesia
4
Key messages 7. Land use for biofuel crops varies with countries Degraded and marginal lands for Jatropha; India, China Forest lands converted for oil Palm; Malaysia, Indonesia 8. GHG implications vary with land conversions involved and countries India & China; degraded lands and with minimal energy input Indonesia & Malaysia - forest lands with high carbon stocks 9. India & China have large biomass power programs for meeting decentralized power needs Largely using degraded lands for producing woody biomass with minimal energy input for production of feedstock Likely to provided large GHG benefits by substituting fossil fuel power & generate power for local applications India has a large number of CDM projects on biomass power
5
Land use options for climate mitigation Biomass power- Large potential (e.g., 30 GW in India) - Woody biomass based - Dedicated energy plantations in degraded lands + crop / forest residue - Large program for decentralized biopower - No serious implications for food security or GHG, since vast degraded land available in most countries Carbon Seq through Afforestation & Reforestation in Degraded lands - large potential - large afforestation programs; - India=1.5Mha, China=4-5 Mha -No serious implications for food security since vast degraded land available in most countries -Large carbon sink creation + non-wood products
6
Land use options for climate mitigation Bio- Ethanol -Sugarcane – program being initiated – sugar is the main product – biofuel byproduct - Sweet Sorghum, Maize, Cassava, etc. – - Marginal scale program Biodiesel- Palm oil – Large program in South east Asian countries - Jatropha – Large program in India, China, etc - Tree species yielding oil seeds such as Pongamia, Shorea, Madhuka, etc in India - No edible oil-based Biodiesel program

Malaysia Palm oil plantations <1 Mha in the 1970s 4 million hectares in 2005. Producing 15 Mt of crude palm oil Target to expand to 5 Mha by 2010 to produce 20 Mt

Indonesia; scale of biofuel program Biodiesel 2005-07 = 212,000 ha 2008 = 663,000 ha 2017 = 2.67 Mha Bio-ethanol 2008 = 50,000 ha 2017 = 54,000 ha

India – scale of biofuel program Biodiesel 2008 = 279,000 ha 2017 = 340,000 ha Bioethanol 2008 = 451,000 ha 2017 = 854,000 ha

Biofuel Production Share of Petroleum and Diesel

Biofuel will be very important in Asia from energy security perspective Need for research and informed debate on implications of large-scale biofuel production / consumption / export GHG emissions Food security and energy security Socio-economic aspects Alternate land uses in the context of climate mitigation & development is required; Biomass power Carbon sink through afforestation Biofules – liquid fuels Solid fuels; charcoal and fuelwood Need for good database for scientifically analysis
