Agriculture is important because….
• accounts for about 1/3 of GHG emissions globally
• can be a significant carbon “sink” by building up soilorganic matter
• is a major user of rural land and water resources and
linked to forestry via land use
• food is a necessity (food security concerns) and
• many of the world’s poor are farmers (development
goals)

Agriculture is unique because …
Climate change has significant but diverse impacts on farming:
location, location, location
• Adaptation is uncertain and economic appraisal difficult
• Mitigation, a range of actions technically possible and
economically feasible
Food security goals
• Policies to encourage a “low carbon” agriculture may impede
the goal of producing more food in the short run, BUT
• Is the real problem the ability to obtain food or the availability
of food – and is this a short or long term issue?
OECD Trade & Agriculture Directorate
5
Challenges
• Provide enough food given pressure on natural
resources
• Encourage farm management practices that reduce
GHGs, sequester carbon, adapt to climate change –
and provide environmental co-benefits
• Take into account externalities through policy
incentives to move agriculture and food consumption
to a “low carbon” path and contribute to “green
growth”
OECD Trade & Agriculture Directorate

Policy approaches
Climate Change
• Mitigation: policies to incentivise farmers to reduce
agriculture’s emissions of greenhouse gases and enhance
carbon capture (sequestration)
• Adaptation: policies to incentivise farmers to manage
adaptation to climate change
Green Growth
• a holistic approach that includes climate change and
more general sustainability criteria …
• ecosystem degradation, pollution and nutrient run-off,
water availability, etc.
OECD Trade & Agriculture Directorate

Green Growth Policies
• Policies to incentivise the agricultural sector to provide enough
food and generate environmental co-benefits (including
reduction of greenhouse gases)
– Address market failures (impacts that are not priced in the market, e.g.
CO2, pollution)
– Reform/remove environmentally harmful subsidies (e.g. fossil fuel)
– Target policies to achieve environmental objectives more effectively
(biofuels costs $ 960-1700 ton CO2 avoided)
– Facilitate green technologies, innovation, information dissemination

Green GROWTH?
Panacea to address financial crisis?
– The need to provide sufficient government stimulus to
boost weak demand (“shovel ready projects”)
– More jobs, more growth, less carbon
Cure worse than disease
– Increase costs on weak economy
– Will not increase employment, give up some growth
Both are right and both are wrong

Green Growth and subsidies
• Agriculture (in OECD) is highly subsidized
– Support to farmers in 2006-08 23% of gross farm receipts (265 B usd)
– Varies widely by country (Nor, Jpn, Kor vs Aus and Nzl)
– However only a fraction (~25%) is actually retained by farmers (higher
input costs, land/production quotas)
• Subsidies and green growth
– Production linked support dominates (more than ¾)
– Higher production may lead to higher input use with environmental
effects (water, soil, biodiv, ghg)
– e.g. Nitrogen efficiency about 55% (30-80) in OECD … wastefully applied
overwhelming the nitrogen cycle
OECD Trade & Agriculture Directorate
11
What is the role of government?
• Ensure a policy environment that sends clear signals that align
the goals of individual farmers and society
• Build capacity to better understand and measure agriculture’s
contribution to sustainable development
• Implement or reform existing policies and insurance systems to
facilitate adaptation by increasing producer resilience to
climate change while compensating those most vulnerable
• Facilitate research to better inform, design and implement
policy – at the domestic and global levels …
OECD Trade & Agriculture Directorate
12
Which policies?
Producers and consumers need to face the right incentives
– Carbon price, explicitly or implicitly (taxes, cap-andtrade…)
– Policy reform: decoupling of agricultural support from
production, removal of fuel tax subsidies, etc.
– Targeted payments for public goods (e.g. biodiversity,
carbon sequestration)
– Regulations for public bads (e.g. pollution, nutrient runoff)
– R&D/Innovation, advice and information, training to
provide farmers with options
OECD Trade & Agriculture Directorate
13
What do farmers need to do?
Specific to production systems, climate/location –
individual farmers know best the economic tradeoffs given the right policy environment
– Adapt to (inevitable) climate change impacts
– Reduce GHG emissions per unit of production, whist
respecting environment ”sustainable intensification”
– Increase carbon sequestration
– Maximise synergies with other environmental outcomes
(biodiversity, water quality, soil erosion…)
OECD Trade & Agriculture Directorate

Main messages
• Ensuring a highly efficient, productive and resilient
agriculture is the key to our future, response to climate
change should be part of an overall effort to achieve
environmental sustainability
• Environmental pressures need immediate attention,
“sustainable intensification” -addressing climate change
is an investment in the future
• The costs and benefits of alternative future scenarios
have not been sufficiently analysed
• Uncertainty about the impact of climate change is a
reason to act
