Outline • Agriculture as the driverof deforestation • Are agricultural mitigation options drivers of deforestation? • Values and costs of agricultural mitigation • Agricultural mitigation as the complement to deforestation

Mitigation technologies in the agricultural sector • Direct mitigation : Emission Reduction • Indirect mitigation : Avoid CO2 emission • Livestock management • Improve feedings practice, dietary additive • Manure management • Improve storage and handling, AD, efficient use of nutrient source
Mitigation technologies in the agricultural sector (cont) • Cropland management • Nutrient management • Tillage/residue management • Water management • Rice management • Agroforestry • Restoration of degraded land • Organic amendment • Nutrient amendment
Mitigation technologies in the agricultural sector (cont) • Biofuel/bioenergy • Biochar • Energy crop : • Sugarcane to bioethanol, • Oil palm to biodiesel
Examples of mitigation technology • Cropland: nutrient management Source: Pongthep and Amnat 2010
Examples of mitigation technology • Cropland: rice field • Water management 30–40% reduction • SRI (system rice intensification) approx 37% reduction • AWDI (alternative wet /dry irrigation) approx 70% reduction • Inhibitor 20–60% reduction Source : Tassanee and Sirintornthep 2010
Values and cost of agricultural mitigation IPCC AR4 WGIII SPM
Abatement cost in rice field: Case of Thailand $10–60 per tonne of CO2e 1 water drainage 2 shift fertilizer 3 combination of 1 and 2 3 3 2 2 1 1
Marginal abatement cost curves for 3rd Baseline technology: continuous flooding , Mixed FYM/urea: straw burning 10-60 US$ /tCe Wassman et al 2007
Value /Co-benefit • Sustainable agriculture • Culture and way of life • Income • Environmental benefit
Agricultural mitigation as the complement to deforestation Food and fuel crop competition -Full utilization of cropland – crop rotation -Improve crop yield Limited land expansion Crop price deforestation Poverty alleviation

Yield from food and fuel rotation crop • Agricultural area of Thailand 130.34 M Rai • Area of rain-fed rice field (2010) 57.50 M rairice yield 23.25 M tonnes • Area of irrigated rice field (2010) 15.22 M rai rice yield 8.86 M tonnes • Sweet sorghum • Cultivation time 90-100 days • Yield 5-7 tonnes per Rai • Syrup from stem 2500-3500 litre per rai • Bioethanol 350-420 litre per Rai

Food Fuel and Forest Policies and incentives Food and fuel crop competition -Full utilization of cropland—crop rotation -Improve crop yield Limited land expansion Crop price deforestation Poverty alleviation
Messages • Sustainable agriculture and agricultural mitigation can be complementary to deforestation • Full utilization of cropland with co-benefits for farmers • Food security can not be addressed without yield improvement. • Policies and incentives are key issue to ensure sustainable agriculture towards negative drivers of deforestation
