Carbon offsets from voluntary avoided deforestation projects are generated based on performance vis-à-vis ex-ante deforestation baselines. We examined the impacts of 26 such project sites in six countries on three continents using synthetic control methods for causal inference. We find that most projects have not significantly reduced deforestation. For projects that did, reductions were substantially lower than claimed. This reflects differences between the project ex-ante baselines and ex-post counterfactuals based on observed deforestation in control areas. Methodologies used to construct deforestation baselines for carbon offset interventions need urgent revisions in order to correctly attribute reduced deforestation to the projects, thus maintaining both incentives for forest conservation and the integrity of global carbon accounting.

Carbon offsets from voluntarily avoided deforestation projects are generated based on performance vis-\`a-vis ex-ante deforestation baselines. We examined the impacts of 27 forest conservation projects in six countries on three continents using synthetic control methods for causal inference. We compare the project baselines with ex-post counterfactuals based on observed deforestation in control sites. Our findings show that most projects have not reduced deforestation. For projects that did, reductions were substantially lower than claimed. Methodologies for constructing deforestation baselines for carbon-offset interventions thus need urgent revisions in order to correctly attribute reduced deforestation to the conservation interventions, thus maintaining both incentives for forest conservation and the integrity of global carbon accounting.

Reduced Emissions from Deforestation and forest Degradation (REDD+) has gained international attention over the past decade, as manifested in both United Nations policy discussions and hundreds of voluntary projects launched to earn carbon-offset credits. There are on-going discussions about whether and how projects should be integrated into national efforts under the Paris Agreement. One consideration is whether these projects have generated additional impacts over and above national policies and other conservation measures. To help inform these discussions, we compare the crediting baselines established ex-ante by voluntary REDD+ projects in the Brazilian Amazon to counterfactuals constructed ex-post based on the quasi-experimental synthetic control method. We find that the crediting baselines assume consistently higher deforestation than counterfactual forest loss in synthetic control sites. This gap is partially due to decreased deforestation in the Brazilian Amazon during the early implementation phase of the REDD+ projects considered here. This suggests that forest carbon finance must strike a balance between controlling conservation investment risk and ensuring the environmental integrity of carbon emission offsets. Relatedly, our results point to the need to better align project- and national-level carbon accounting.

Evidence-based approaches to sustainability challenges must draw on knowledge from the environment, development and health communities. To be practicable, this requires an approach to evidence that is broader and less hierarchical than the standards often applied within disciplines.

Reducing emissions from deforestation and forest degradation (REDD+) is expected to generate co-benefits and safeguard the interests of people who live in the forested regions where emissions are reduced. Participatory measurement, reporting and verification (PMRV) is one way to ensure that the interests of local people are represented in REDD+. In order to design and use PMRV systems to monitor co-benefits and safeguards, we need to obtain input on how local people perceive REDD+. In the literature, this is widely discussed as "community perceptions of REDD+." We systematically reviewed this literature to understand how these perceptions have been assessed, focusing specifically on how individual perceptions have been sampled and aggregated into "community perceptions." Using Google Scholar, we identified 19 publications that reported community perceptions of REDD+, including perceptions of its design, implementation, impacts, relationship with land tenure, and both interest and actual participation by local people. These perceptions were elicited through surveys of probability samples of the local population and interviews with purposively selected community representatives. Many authors did not provide sufficient information on their methods to interpret the reported community perceptions. For example, there was often insufficient detail on the selection of respondents or sampling methods. Authors also reported perceptions by unquantified magnitudes (e.g., "most people", "the majority") that were difficult to assess or compare across cases. Given this situation in the scholarly literature, we expect that there are even more severe problems in the voluminous gray literature on REDD+ not indexed by Google Scholar. We suggest that readers need to be cognizant of these issues and that publication outlets should establish guidelines for better reporting, requiring information on the reference population, sampling methods, and methods used to aggregate individual responses into "community perceptions."

This report reviews the literature on the links between energy access, welfare, and gender in order to provide evidence on where gender considerations in the energy sector matter and how they might be addressed. Prepared as a background document for the 2012 World Development Report on Gender Equality and Development, and part of the Social Development Department's ongoing work on gender and infrastructure, the report describes and evaluates the evidence on the links between gender and energy focusing on: increased access to woodfuel through planting of trees and forest management; improved cooking technologies; and access to electricity and motive energy. The report's main finding is that energy interventions can have significant gender benefits, which can be realized via careful design and targeting of interventions based on a context-specific understanding of energy scarcity and household decision-making, in particular how women's preferences, opportunity cost of time, and welfare are reflected in household energy decisions. The report focuses on the academic peer-reviewed literature and, although it applies fairly inclusive screening criteria when selecting the evidence to consider, finds that the evidence on many of the energy-gender linkages is often limited. There is thus a clear need for studies to evaluate interventions and identify key design elements for gender-sensitive project design.

What are the unique challenges and benefits of natural resource education overseas? This session addressed these questions in the context of short-term study programs in forestry and other natural resource fields. The panel included Tom Hammett, Virginia Tech, who leads summer programs in Australia; Geoff Habron, also of Michigan State University, who leads a summer program in the Brazilian Amazon; Bruce Bongarten of the University of Georgia, which offers several month-long courses in conservation issues, including one to South Africa; Kim Steiner of Pennsylvania State University, which has an exchange study program with Freiburg University in Germany; Gary Blank and Steve McKeand, NC State University, who coordinate an exchange study program with SLU in Sweden; and Ingrid Schmidt and Kristi Hubbard of the NC State Study Abroad Office. My experience with international natural resource education is designing and leading spring-break trips to Latin America. We also had input from many other faculty who have led-or are planning-study programs in natural resource issues around the world.

The economic impact of migrant farmworkers on an agriculture-dependent region is investigated. The direct effects of inflows of state and federal dollars for migrant services, and production of high-valued commodities are computed. Indirect and induced effects are modelled through the use of the IMPLAN input output model. Various alternatives to migrant labor are investigated, including production of less labor-intensive crops, acreage retirement, and contract H2A workers. Migrants are found to create substantial economic activity on the Eastern Shore of Virginia.
