Food Sovereignty and Climate Change:Smallholder Farming Can Cool Down the Earth* M. Jahi Chappell School of Earth and Environmental Sciences Washington State University Vancouver
*Effects of Industrial Agriculture on Global Warming and the Potential of Small-Scale Agroecological Techniques to mitigate those Effects B. B. Lin,M. J. Chappell, J. Vandermeer,G. Smith, I. Perfecto, E. Quintero, R. Bezner-Kerr, D. Griffith, S. Ketcham, S. Latta, P. McMichael, K. McGuire, R. Nigh, D. Rocheleau and J. Soluri (in review)
Agriculture and Global Climate Change • Agriculture generates ~31% of anthropogenic Greenhouse Gases (GHGs) • 10-14% from direct emissions • 12-17% from agriculture-driven land conversion IPCC 2007; Scialabba and Müller-Lindenlauf 2010
Agriculture and Global Climate Change • “Little doubt” industrial agriculture is disproportionately responsible for agriculture-generated GHGs • Small-scale agroecological farms can help via reducing emissions & sequestering carbon (mitigation) Scialabba and Müller-Lindenlauf 2010; Niggli et al. 2009; Lin et al., in review
Agroecological and Industrial Agricultural Approaches • Industrial (Green Revolution) methods: pursues high productivity through intensive use of time and space, larger scales, synthetic inputs, mechanization, and homogenization • Agroecology: seeks to integrate and replicate existing ecosystem processes, in turn minimizing or eliminating external and synthetic inputs

Agriculture and Global Climate Change • Land Conversion and Productivity • Speaking Practically About Practices • Other Issues • Food Sovereignty, Human Rights, and Hunger
Land Conversion and Productivity:Historically “Spared” Land (and Carbon)? • Recent and earlier studies indicate “land-sparing” effect is not generally seen • Small number of cases of “land-sparing” tied to increased grain imports; another study found per capita agricultural exports to be one of the most predictive factors for deforestation Angelsen and Kaimowitz 2001; Ewers et al. 2009; Rudel et al. 2009; Perfecto and Vandermeer 2010; DeFries et al. 2010
Smallholders and deforestation • Significant amounts of deforestation due to large farmers; FAO data from 1990 to 2000 found: • Large landowners responsible for majority of deforestation in Latin America, Asia, Pacific • Smallholders responsible for majority in tropical Africa • Harder to measure but vital to consider (and study!): • Industrial/large-scale agriculture helps create the conditions that push small farmers into further deforestation • Direct expropriation of lands, competition, subsidy structures, labor: “lock” on productive resources • Food sovereignty and land reform FAO 2009; Vandermeer et al. 2009Sloan 2007; Weis 2007
Smallholders and deforestation • DeFries et al. 2010: Small-scale producers are no longer the dominant driver of deforestation in many places (from data set for 2000-2005) • Exports and Urban Population Growth Rate
Agricultural Practices + means positive effect on mitigation - means negative effect (more emissions) Lin et al., in review; based on Smith et al. 2008

Agricultural Practices Niggli et al. 2009, with data from Lal, 2004
Other Issues • Disruption of Global N and C cycles • “From an energy producer to an energy consumer” • Organic/agroecological systems are 20-40% more energy efficient than conventional/industrial systems (e.g. Pimentel 2006) • Small farm productivity • Inverse Relationship (Microclimates? More research needed…) • Largest productivity gains likely in least productive areas (Badgley et al. 2007; Hine et al. 2008) • The Trouble with Televory and Daly’s Danish Cookies
Food Sovereignty and Human Rights • Hunger doesn’t come from a lack of food, but a lack of food sovereignty • More than enough food in the world • Structural adjustment, food reserves, international markets, imports/exports • Past decreases in hunger have come principally from the provision of human rights Chappell and Lavalle 2009, Weis 2007, Davis 2002; Smith and Haddad 2000
