This document discusses agroforestry systems for environmental restoration in Brazil that balance social and ecological functions. It outlines that agroforestry can: (1) maintain ecosystem structure/functions like biodiversity and soil quality while providing social/economic functions for family farms; (2) perform restoration in an economically feasible way by including people and accelerating natural succession; and (3) improve livelihoods through appropriate management. However, balancing trade-offs between social/environmental benefits and costs is challenging. The document then provides examples of agroforestry systems for restoration in Brazil and their costs, benefits for climate change adaptation/mitigation, food security, and carbon storage potential.

3. Objetives of restoring environmentally sensitive areas –
social and ecological functions (Brazilian Forest Code)
• Maintenance of the original ecosystem structure and functions
• Biodiversity (habitat, migratory corridors, gene flow)
• Soil structure and fertility, nutrient cycling
• Water infiltration/water recharge, erosion control
• Buffer strips
• Social and economic functions (family farming)
Restoration through Agroforestry Systems
• Perform these functions
• can render restoration economically feasible
• Include humans in restoration and conservation
• accelerate natural succession (through management)
• Improve farmer livelihoods and quality of life
Thus, human beings need to be included in restoration and
can contribute to advancing succession of species

4. Appropriate management accelerates succession and
optimizes resources

5. Ok….but…
• Which systems balance trade-offs between social and
environmental functions, between costs and benefits?
• How to balance these trade-offs in practice?

7. Climate Change
– MITIGATION
• High C sequestration potential
• Increases organic soil carbon
• Lower emissions Vs slash and burn
or monocultures with chemical inputs
– ADAPTATION
• Modifies microclimate: protects sensitive crops, windbreak, lower
temp and higher humidity
• Increases resilience (plants and farmers), extends harvest season,
alleviates extreme events (prolonged droughts, floods)
(Tito et al., 2011; Silva et al., 2011; Nunes & Vivan, 2011; Jacobi et al.,
2013; Torres et al., 2014; Fernandes et al., 2014; Marinho, 2014)

9. Social and Economic Benefits
• Increases food security and sovereignty
(diversity, quality, independence)
• Reduces risks and vulnerabilities to shocks and stresses
– economic risks of investing
– Market and policy fluctuations
– Pests and disease
– Extreme climate events
• Reduces need for external inputs
• Distributes labor/income throughout the year
(Ayres, 2008; Padovan et al., 2009; Santos, 2010; Barbieri &
Valdivia, 2010; Vivan, 2010; Steenbock et al., 2013; Fonini,
2014; Mendes et al., 2014; Vira et al., 2015)

10. Social and economic benefits
• Working in the shade, quality of life, self-esteem,
well being, leisure, culture
• Strenghtens social cohesion, unity
• Maintenance of agro-biodiversity

13. Oil Palm + Agroforestry
“SAFDendê” Project
• Annual crops: 3-4 years (cassava,
maize, short-cycle legumes)
• Fruit trees/cash crops: cacao, açaí
(euterpe oleracea), banana, bacaba
(oneocarpus bacaba), black pepper
• Timber, fertilizer trees
• Intense management, slash-and-
mulch
• Organic/agroecological systems (no
chemical inputs)
• First of its kind

How do these constraints vary across the landscape/per value web?

KEY CONSTRAINTS
• Vary greatly from chain to chain, geo location
and farmer types, BUT…
• Overall, great dependence on middlemen
• Greatest constraint for fruit pulps = processing +
• Low level of social organization
• Access to credit (due to high default, procedural
barriers)
• technical assistance/extension for biodiverse AF

What are the key ingredients of inclusive oil palm agroforestry business model?
Oil palm
Inclusive business model?
• Optimal size of AF + OP for family farmers to
establish/yr?
• Technological package: use of inputs/labor for
other crops?
• How to share risks and benefits?
