Cost and equity implications of integrating sticks and carrots in

conservation programs in Brazil and Peru

Background

• Mounting empirical evidence suggests that Brazil has effectively reduced deforestation to 70-80% of pre-2004 levels (Hargrave and Kis-Katos, 2013)

• Command-and-control (stick) policies are relatively cheap to implement (Börner et al., 2014)

• Effective C&C requires complementary incentive-based policies to be sustainable in the long-run (Nepstad et al., 2014)

Research questions

1. What tradeoffs in terms of cost-effectiveness and land user income do policy makers face when attempting to integrate sticks (C&C) and carrots (PES) for forest conservation (Brazil)?

2. How can the incentive component be designed to make conservation both cost-effective and fair (Peru)?

Study areas

Study areas

BRAZILIAN AMAZON

• High historical deforestation

• High concentration of land ownership

• Commercial agriculture and cattle operations at the agricultural frontiers

• Relatively well developed forest monitoring and law enforcement infrastructure

• Large-scale PES planned

PERUVIAN AMAZON

• Historically low deforestation

• Relatively homogeneous distribution of land

• Predominantly subsistence cattle production and small but growing commercial sector

• Relatively weak forest monitoring and law enforcement infrastructure

• Large-scale PES implemented

Modelling decisions

Land user

• Deforestation is a function of expected profits and policy incentives

EPA

• Enforcement is a budget constrained optimization of deterrence through in situinspections

Spatial analysis

• District-based opportunity cost analysis

• Grid-based spatial simulation of:– Avoided deforestation (Brazil + Peru)

– Land user income change (Brazil + Peru)

– Command-and-control implementation costs (Brazil)

– Sticks & Carrot integration (Brazil)

– Alternative PES payment modalities (Peru)

Key findings

• Mixing carrots to sticks can make REDD+ fairer, but also more expensive (Brazil)

• If PES are intended to complement C&C (as common under REDD+) enforcement quality is key to cost-effectiveness (not necessarily fairness)

• Designing PES requires knowledge about spatial patterns of deforestation and opportunity costs

• Simple and feasible adjustments to the PNCB can boost its cost-effectiveness and equity effects
