Bigger is Better: Avoided Deforestation Offsets in the Face of Adverse Selection AgEcon
van Benthem, Arthur A.; Kerr, Suzi.
Voluntary opt-in programs to reduce emissions in unregulated sectors or countries have spurred considerable discussion. Since any regulator will make errors in predicting baselines and participants will self-select into the program, adverse selection will reduce efficiency and possibly environmental integrity. In contrast, pure subsidies lead to full participation but require large financial transfers. We present a simple model to analyze this trade-off between adverse selection and infra-marginal transfers. We find that increasing the scale of voluntary programs both improves efficiency and reduces transfers. We show that discounting (paying less than full value for offsets) is inefficient and cannot be used to reduce the fraction of offsets that are...

CONFLICTOS NORMATIVOS ASOCIADOS CON EL DERECHO DE PROPIEDAD DE LAS COMUNIDADES INDÍGENAS Y AFRO EN ÁREAS DE BOSQUES, ZONA COSTERA DE COLOMBIA* Boletín de Investigaciones
Villa Porto,Claudia; Sierra-Correa,Paula Cristina.
La puesta en marcha de la estrategia de las Naciones Unidas de "Reducción de emisiones por deforestación y degradación forestal evitada (REDD)" como medida de mitigación a los efectos del cambio climático en áreas de bosques de Colombia, encuentra soporte para su implementación en los convenios internacionales de los cuales el país hace parte. Algunos pasos de la metodología aplicable en proyectos REDD presenta conflicto con el marco jurídico vigente en Colombia, referido a la propiedad colectiva de las comunidades indígenas y afro que habitan o hacen uso de los bienes y servicios ambientales de los bosques que interesan a procesos REDD. Se concluye que la jurisprudencia sobre aspectos costeros respecto a la de aprovechamiento de recursos forestales es...

Designing REDD+ Schemes to Address Permanence Concerns: Empirical Evidence from Kenya AgEcon
Veronesi, Marcella; Schlondorn, Tim; Zabel, Astrid; Engel, Stefanie.
Reducing Emissions from Deforestation and Forest Degradation (REDD+) is an important topic in the debate on policies to mitigate climate change. This is the first study to test and compare the environmental impact of different REDD+ payment schemes in the field, and provide some insights on the effectiveness of different policies with respect to the permanence of forest-based emission reductions. This study implements a stated preference experiment of time allocation in the unique setting of the Kasigau Corridor REDD+ Project in Kenya, where charcoaling is a major source of forest degradation. The impact on time allocation is analyzed under the presumption that a hypothetical agricultural policy or an eco-charcoaling policy was introduced. We find that a...

Effects of Low-cost Offsets on Energy Investment – New Perspectives on REDD – AgEcon
Golub, Alexander; Fuss, Sabine; Szolgayova, Jana; Obersteiner, Michael.
Tropical deforestation is one of the major sources of carbon emissions, but the Kyoto Protocol presently excludes avoiding these specific emissions to fulfill stabilization targets. Since the 13th Conference of the Parties (COP) to the UNFCCC in 2007, where the need for policy incentives for the reduction of emissions from deforestation and degradation (REDD) was first officially recognized, the focus of this debate has shifted to issues of implementation and methodology. One question is how REDD would be financed, which could be solved by integrating REDD credits into existing carbon markets. However, concern has been voiced regarding the effects that the availability of cheap REDD credits might have on energy investments and the development of clean...

Optimizing Voluntary Deforestation Policy in the Face of Adverse Selection and Costly Transfers AgEcon
van Benthem, Arthur A.; Kerr, Suzi.
As part of international climate change policy, voluntary opt-in programs to reduce emissions in unregulated sectors or countries have spurred considerable discussion. Since any regulator will make errors in predicting baselines, adverse selection will reduce efficiency since participants will self-select into the program. In contrast, pure subsidies lead to full participation but require large financial transfers; this is a particular challenge across countries. A global social planner facing costless transfers would choose such a subsidy to maximize efficiency. However, any actual policy needs to be individually rational for both the buying (industrialized) and selling (developing) country. We present a simple model to analyze this trade-off between...

Relações empíricas entre características dendrométricas da Caatinga brasileira e dados TM Landsat 5 PAB
Almeida,André Quintão de; Mello,Anabel Aparecida de; Neto,Antônio Luiz Dória; Ferraz,Raphael Cavalcanti.
O objetivo deste trabalho foi ajustar modelos para estimar características dendrométricas da Caatinga brasileira a partir de dados do sensor TM do Landsat 5. Medidas de diâmetro e altura das árvores foram obtidas de 60 parcelas de inventário (400 m2), em dois municípios do Estado de Sergipe. A área basal e o volume de madeira foram estimados com uso de equação alométrica e de fator de forma (f = 0,9). As variáveis explicativas foram obtidas do sensor TM, após correção radiométrica e geométrica, tendo-se considerado, na análise, seis bandas espectrais, com resolução espacial de 30 m, além dos índices de razão simples (SR), de vegetação por diferença normalizada (NDVI) e de vegetação ajustado ao solo (Savi). Na escolha das melhores variáveis explicativas,...

Contemporary conservation interventions must balance potential trade-offs between multiple ecosystem services. In tropical forests, much attention has focused on the extent to which carbon-based conservation provided by REDD+ policies can also mitigate biodiversity conservation. In the nearly one-third of tropical forests that are community owned or managed, conservation strategies must also balance the multiple uses of forest products that support local livelihoods. Although much discussion has focused on policy options, little empirical evidence exists to evaluate the potential for trade-offs among different tropical forest value components. We assessed multiple components of forest value, including tree diversity, carbon stocks, and both timber and...

Uncertain Emission Reductions from Forest Conservation: REDD in the Bale Mountains, Ethiopia Ecology and Society
Watson, Charlene; London School of Economics and Political Science; c.watson2@lse.ac.uk; Mourato, Susana; London School of Economics and Political Science; s.mourato@lse.ac.uk; Milner-Gulland, E. J.; Imperial College London; e.j.milner-gulland@imperial.ac.uk.
The environmental integrity of a mechanism rewarding Reduced Emissions from Deforestation and Degradation (REDD) depends on appropriate accounting for emission reductions. Largely stemming from a lack of forest data in developing countries, emission reductions accounting contains substantial uncertainty as a result of forest carbon stock estimates, where the application of biome-averaged data over large forest areas is commonplace. Using a case study in the Bale Mountains in Ethiopia, we exemplify the implications of primary and secondary forest carbon stock estimates on predicted REDD project emission reductions and revenues. Primary data estimate area-weighted mean forest carbon stock of 195 tC/ha ± 81, and biome-averaged data reported by the...
