20,000 species of plants, 263 mammals, 936

birds, 306 reptiles and 475 amphibians

(Mittermeier 2005, Ribeiro 2011)

Endemism approx. >%30 (Mittermeier 2005)

100 million people.

The Atlantic Forest

• 85% deforested.

• >50% remaining forest in fragments of <100 ha.

• Forest cover of 30% likely needed to prevent massive extinctions and loss of resilience.(Banks-Leite et al., 2014)

• A closing window of opportunity to act.

Santa Catarina – family farmers and livelihoods

• 88 % own land

• 87% of agricultural output, 44% of land

• 90% of rural population

• Tenuous hold on the “global middle

class.”

• Rural-urban migration important issue.

• “Outlaw Farmers”: not in compliance w/

Brazilian Forest Code.

The choice between’s : “larger farms or larger favelas.”-Luiz Henrique da Silveira

Is there a way out?

Stage 1: Voisin Rotational Grazing (Management Intensive Grazing).

From 0 to statewide program (EPAGRI) in 15 years.

Farmer reports:• 75% increase in stocking rates.• 28% increase in milk/cow• Over 100% increase in milk

yield and revenue.• Alvez, et al 2012

Detailed Farm Finance Surveys:• 60% higher income/ha and

profit/ha compared with non-Vosin Farmers.

• Brasiliero, et al forthcoming

Stage 2: Hi-Biodiversity Silvopastoral Systems

• Nucleation system

• Provide Shade and windbreaks

• Euterpe edulis (juçai fruit), Mimosa scabrella (bracatinga: nitrogen fixation, timber, honey), other NTFPs, charcoal trees, etc.

• Bananas (the non-native exception)

• Wild bees?

• >60 farmers signed up for pilot.

Stage 3: Riparian Agroforestry, HBSPS and new approaches to Ecosystem Services

• Goal is to comply with and exceed the forest code using agroforestry systems with native species.

• Most farmers feel they cannot comply with forest code.

• Biodiversity conservation (habitat matrix) and watershed services.

• Working with Secretariat of Sustainable Development on ecosystem services scheme in collaboration with farmers

Page 13: Silvopasture and Riparian Agroforestry in Santa Catarina ...Silvopasture and Riparian Agroforestry in Santa Catarina: An Alternative Approach to Ecosytem Services Ben Dube University

Hypothesis:

• Research, extension, support and cost-sharing for agro-forestry (a co-investment paradigm) can restore ecosystem functions more cost-effectively and reliably than Commodification of Ecosystem Services.

Page 14: Silvopasture and Riparian Agroforestry in Santa Catarina ...Silvopasture and Riparian Agroforestry in Santa Catarina: An Alternative Approach to Ecosytem Services Ben Dube University

Rationale

Problems with CES

• Political and Economic Risks (from local to global)

• High transaction costs• Hard to fund small family farms.

• Opportunity costs fluctuate.

• May erode social economy• “Crowding out” altruism.

Benefits of Co-investment in Agro-Forestry

• One-time financial outlay• Repayment could allow system to

self-support.

• Lower transaction costs• Embedded in existing co-op /

extensionist relationships.

• Value of products fluctuates with opportunity costs.

• May promote the social economy. • Reciprocity over quid pro quo.

Design Parameters:

• Proportion of public vs farmer investment.• Loans? Free trees? Planting assistance?

• Proportion of commodity revenue shared with government.• Based on initial assistance? “loan repayment”

• Based on system revenue? A “tax” or “in-kind contribution”

• A mix?

• None?

• Proportion of commodity vs ecosystem service flows.• Ex: % native trees. % non commodity trees.

Economic Qualities

Positive Factors

• Shade for cows in summer.

• Higher quality forage in summer.

• High quality browse as supplemental forage.

• Diversified income streams.

• Income added with low labor costs and low external inputs.

Negatives/Risks

• Shade impacts on winter forage growth.

• Long wait until system matures (time value of $).

• New commercial crop.

• Large up front costs.

SPS coinvestment Conservation PES

• R$1500-2000/ha/yrindefinitely. (50-70% of avg profit).

• Long term, much greater ES.

• R$7,400/ha once.

• Fast ES provision

• Long-term revenue positive for local gov (repayments & economic activity.)

Multifunctional Riparian Forest Coinvestment

• R$11,600/ha once• Fast ES provision• Regulatory compliance

for farms• Meets farm opportunity

Some Questions for the Future

• How will systems actually evolve?• Ongoing monitoring and research investigation.

• How do farmers view the co-investment?• Can we activate financial and intrinsic motivations?

• Quantifying and Valuating Ecosystem Services

• Can/should international carbon markets help fund projects for local ecosystem services?
