The Effects of Storage Technology and Training on Post-Harvest Losses. Evidence from Small-Scale Farms in Tanzania

Submitted by Anonymous (not verified) on

We analyze the impact of a new storage technology and training on post-harvest losses among small-scale maize farmers in rural Tanzania. The analysis is based on data collected by means of a randomized controlled trial (RCT) in which farmers were randomized into one of three groups: a control group and two treatment groups. Farmers in the first treatment group received training on post-harvest management practices, and farmers in the second treatment group were provided with hermetic (airtight) bags for storing maize, as well as the training administered to the first treatment group.

Community-based wildlife management failing to link conservation and financial viability

Submitted by Anonymous (not verified) on

Given the considerable popularity of community-based wildlife management as a conservation tool, it is of interest to assess the long-run sustainability of this policy not only in conservation terms, but also in financial terms. In this paper, we use cost–benefit analysis to study the social and financial sustainability of a large set of community conservancies in Namibia, one of the few countries where community-based wildlife management policies have been in place long enough to assess their long-term viability.

Labor as a Utility Measure in Contingent Valuation: Application to the Valuation of Restoration Projects in Latin America

Submitted by NENRE Concepcion on

Monetary contributions might not be an appropriate welfare measure in Contingent Valuation (CV) when household incomes are very low. In such cases, willingness to pay (WTP) is restricted by household's ability to reduce the consumption of other goods in order to pay for the environmental good under valuation. Beneficiaries, however, may be willing to contribute their time to work on the project instead of paying money.

Determining Benefits and Costs for Future Generations

Submitted by Anonymous (not verified) on

This article is a good example of EfDs mission: combining policy advice and research. It is based on a consultancy for the US EPA who asked Maureen Cropper to lead a process with a panel of experts to help advise them on what discount rate to use for climate change – and specifically about falling discount rates. This paper (and a longer one in REEP that is forthcoming) is a byproduct of that work.

Discounting: Unbalanced Growth, Uncertainty, and Spatial Considerations

Submitted by Anonymous (not verified) on

The economics of climate change and the various measures that should be implemented to reduce future damages are highly tied to the use of cost-benefit analysis. Traditional approaches ignore the fact that environmental amenities do not experience the same growth rate as do most of the sectors in the economy, which leads to changing relative prices. Uncertainty should also be considered, especially when one is conducting cost-benefit analysis involving the long-run damages from climate change.

Opportunity costs of conservation: The case of protected area management in the Kakamega Forest, Western Kenya

Submitted by admin on

Knowing the local opportunity costs of restricting access to forest land and resources for conservation purposes is an important input to the design of cost-effective conservation schemes that minimize adverse effects on poor forest users.

China's 11th Five-Year Plan and the Environment: Reducing SO2 Emissions

Submitted by admin on

China's rapid economic growth has been accompanied by a high level of environmental degradation. One of the major sources of health and ecosystem damages is sulfur dioxide (SO2). Reducing SO2 emissions is a priority of China's environmental authorities, and the 11th Five-Year Plan (2006–2010) includes the target of reducing total SO2 emissions by 10 percent from the 2005 level.
