Findings• Science and data gaps create uncertainty about the
viability of cattle ranching intensification as a climate mitigation strategy with livelihoods benefits. To be verifiable, cattle ranching intensification programs (CRIPs) should fund better cattle systems data and science.
• Viability is strongly contingent on the system boundary of the analysis conducted. Consistency is important, entirely normative choices are inevitable.
• How short is the short run?

Motivation
• Several emerging terrestrial climate mitigation strategies depend on “land sparing” by intensifying cattle ranching in Brazil (Gouvello, 2010;Embassy of Brazil, 2010; Ecofys, 2011) . But are Brazilian cattle ranching intensification programs (CRIPs) viable “land sparing” strategies?

By Intensification we mean Land Use Intensification
• any combination of production or management practices that leads to all or part of the Brazilian cattle sector producing more cattle products per land unit. This could mean boosting non-land inputs, boosting output, boosting the quality of the land input, or some combination of these things.
• This doesn’t necessarily mean feedlots

Intensificationland sparingghg mitigation rationale
~200 million cattle in Brazil~200 million hectares of pasture
= ~1 cow/hectare !!
Can an intensification policy reduce deforestation and spare land (Green, 2005; de Gouvello et al., 2010)?
6
Origins of the focus on intensification
• Pasture associated with 80% of deforestation in Brazil– ~0.8=Pi/Di where for Amazonian census tract i, P=pasture
area in 2006 agricultural census and D is cumulative deforestation classified by PRODES, 2004-2006.
• “Pasture is responsible for almost 80% of total deforestation in the legal Amazon [of Brazil]” (Federal Government of Brazil, 2004; Bustamante et al. 2009; Greenpeace, 2010)
• Cattle Ranching intensification a keystone of Brazilian climate change mitigation plans (Gouvello, 2010 )

Pitfalls (1): Uncertainty
Pasture productivity estimates (in tDM/ha/yr)Source: Cohn et al., In Prep.
Pitfalls (2a): Intensification leaks• Cohn & O’Hare (In
Preparation)use survey research to show that in Mato Grosso State, Brazil 5-20% of revenue spent on farming goes to expansion (land purchases or new rental properties).
• Agricultural capital is mobile. Farms on the forest frontier don’t have higher extensification investments. Subsidizing intensification could increase short—run deforestation.

• Boosting cattle density in Brazil could greatly reduce global greenhouse gas emissions from land use change, but not by sparing Brazilian land for forests and fuels. According to our simulation, subsidizing greater cattle density in Brazil might increase substantially the amount of cattle products Brazil produces, but might not actually prevent an increase in the overall area of pasture in Brazil. The mechanism for reduced emissions is displacement of cattle production and associated deforestation in other countries
Pitfalls (2b): Subsidy Could Cause Land Sparing Abroad (Mha 2010-2030)
Pitfalls (3): Rangeland Performance Metrics Needed
