The fate of the Amazon under a BAU scenario SimAmazonia. Landmark presentation of scenarios of development and conservation policies Davidson et al. 2012 Soares-Filho et al. 2006

What happened? From 2004 deforestation in the Amazon plummeted by 80%, more than 2 billion tons of CO 2 reduced from the 1996-2005 baseline. Nepstad et al. 2009

New paradigm in PA history (green barriers) 50% of the remaining forest Effective in locally deterring deforestation without leakage Soares-Filho et al. 2010

But what else? More command and control (IBAMA, Federal policy, public prosecutors) PRODES Near-real time Enforcement teams guided up by deforestation maps Börner et al. 2014

What can we expect? Revisions to the forest code Full reverse? Continued trend of increasing demand for agricultural products from Brazil. Production needs to increase by 40% to raise world production by 20% (OCDE 2015)

Conservation Conflicting interests Development

The forest code is the main conservation tool in Brazil Roughly 53% of Brazil s native vegetation occurs on private properties Soares-Filho et al. 2014

Level of compliance Brazil s new forest code Brazil s controversial new Forest Code grants amnesty to illegal deforesters Debt reduced by 58%, conservation requirements maintained, except for hilltop preservation areas Public lands Soares-Filho et al. 2014

Develop a low carbon agriculture to compensate ag. expansion Although more efficient, emissions will increase in the energy sector due to more consumption Emissions from land use change must reduce by 70% Brazil s NDC by 2030 1800 1600 1400 1200 1000 800 600 400 200 0 486 479 135 778 423 475 2014 2030 Mudança Land use change do uso do solo Energia Energy Agricultura Agriculture Processos industriais Industrial process (Spencer & Pierfrederici, R., 2015)

Large-scale measures relating to land use change and forests 1. Strengthen the Low Carbon Agriculture Program (ABC), including restoration of an additional 15 million ha of degraded pasturelands (totaling 30 Mha). 2. Enforcing the implementation of the Forest Code, at federal, state and municipal levels. 3. Restoring and reforesting 12 million ha of forests by 2030. 4. Zero illegal deforestation by 2030 and compensating for greenhouse gas emissions from legal suppression of vegetation by 2030.

if cattle ranching is intensified from 1 to 1.5 head/ha World Bank 2010 Simbrasil/Otimizagro Soares-Filho et al. 2012

Meet Brazil s new conservationist A spate of publications are suggesting that cattle intensification could spare land for conservation

Based on the theory of land sparing Does it work? Green et al. 2005, Phalan et al. 2011

Others Brazil Soy 3.5 3.0 2.5 2.0 1.5 1.0 0.5 0.0

There is no causation relationship Deforestation is a quest for land, cattle ranching the cheapest means Bowman et al. 2012

2. Enforcement of the Forest Code All properties (5.4M) must enter an online registry system (SICAR) 2-year countdown period By May 2005, 212 Mha, 54% of properties And start developing their PRA, landowners commitment to restore the FC debt.

3. Restoring and reforesting 12 million ha of forests by 2030 35.7 Mha Forest Code Debt Legal reserves + Riparian protection areas 18.5 + 5.5 = 24 Mha. Soares-Filho et al. 2014.

Too costly!! Induced restoration is costly R$ 42 million for 3 thousand ha US$ 7,000 per ha

Costs/benefits of FC compliance Azevedo, Rajão, et al, (under review)

Mtons CO 2 eq 4. End of illegal deforestation and compensating for GHG from legal deforestation by 2030 Emissions from simulated legal deforestation Sequestration by restoration of the FC debt Fallacy of zero net deforestation!

Ambitious targets but weak policies Study casts doubts on Brazil s NDC targets Rajão and Soares-Filho 2015

Brazil s market for trading forest Cota de Reserva Ambienta (CRA): Lower the cost of compliance

Offsetting FC debts with FC surplus (CRA) 4.2 Mha US$ 9.2 billion Rajão and Soares, 2014; Soares-Filho et al. in review

Going beyond Legal Reserve compensation Brazil s forest certificates (CRA) open the door to ecosystem service payments Rajão, Soares-Filho (2015); Soares-Filho, Rajão et al (2016)

US$ 8.4±2.0 billion to purchase low-cost CRAs could cut legal deforestation (19 Mha) in half, saving as much as 3.8±0.8 billion tons of CO 2 emissions Rajão and Soares, 2014; Soares-Filho et al. in press
