China Can Supply About 250 Million Metric Tons of Crop Residues for Bioenergy Production Every Year

We use county-level data on crop yields and cropland to estimate the potential biomass supply from crop residues in China. We find that China can potentially produce about 250 million dry metric tons of crop residues per year when biomass prices are greater than $100 per metric ton. We also find that rice straw is expected to account for about 47% of total residue production, while corn stover (residue) can contribute 28% to total biomass production in China and wheat straw can contribute 25%.


A Bioeconomic Analysis of Community Wildlife Conservation in Zimbabwe

This paper uses a bioeconomic model to analyse wildlife conservation in two habitats adjacent to a national park by two types of communities in the context of Southern Africa. One community is made up of peasant farmers operating under a benefit-sharing scheme (CAMPFIRE) while the other is made up of commercial farmers practising game farming in a conservancy (the Save Valley Conservancy). Both communities exploit wildlife by selling hunting licenses to foreign hunters but with different levels of success.


Allocating Community-Level Payments for Ecosystem Services: Initial Experiences from a REDD Pilot in Tanzania

Payments for ecosystem services (PES) typically reward landowners for managing their land to provide ecosystem services that would not otherwise be provided. REDD— Reduced Emissions from Deforestation and Forest Degradation—is a form of PES aimed at decreasing carbon emissions from forest conversion and extraction in lower-income countries. A key challenge for REDD occurs when it is implemented at the community rather than the individual landowner level.


Disadoption, Substitutability, and Complementarity of Agricultural Technologies: A Random E ects Multivariate Probit Analysis.

In this paper, we analyze what drives farmers to disadopt green revolution technologies (inorganic fertilizer and improved seed) and whether the disadoption of green revolution technologies is related to adoption/non-adoption of other sustainable land management practices (such as farmyard manure and soil and water conservation practices). Random e ects multivariate probit regression results based on rich plot level data suggest that black/brown soil type, atter slope, shorter distance to homestead and extension centers, and access to water are negatively


Decentralization, Market Integration, and Efficiency-Equity Trade-Offs: Evidence from Joint Forest Management in Ethiopian Villages

Extant literature on Joint Forest Management (JFM) impact evaluation has concluded that it generally does not provide sufficient incentives to justify the costs that forest use restrictions impose on local people. However, there is a dearth of evidence concerning whether alternative JFM intervention with improved market linkages for non-timber forest products has similar implications. In this study, we evaluated the income and distributive effects of a JFM program in Ethiopia in which additional support was provided for improved market linkages for non-timber forest products (NTFPs).


Wildlife: An Income Stream for Rural Zimbabweans

When poor rural families in Zimbabwe are able to collect bushmeat, it may allow them to increase their household income through selling the meat within their communities. This means that, if policies help support communities’ access to wildlife, they can address poverty and decrease income inequality in these areas.


Implementing REDD+ Through Village-Level Forest Management Institutions

REDD+ (Reduced Emissions from Deforestation and Forest Degradation) is a form of payment for ecosystem services (a voluntary transaction in which a buyer makes a payment to a seller conditional on the ecosystem providing some service, such as carbon storage) aimed at decreasing carbon emissions from conversion of forest to farm land and unsustainable harvesting of forest resources in lower-income countries. Community-based forest management (CBFM) can create the appropriate incentives and behavioural change required by REDD+ when the recipients of the REDD+ funds are also the key causes of that forest change.


Decisiones de localización y cambios regulatorios: el caso de la acuicultura en Chile

Se estudia la evolución de la actividad acuícola en Chile y el impacto de los cambios regulatorios sobre las decisiones de localización de los centros de cultivo. Este estudio considera un análisis descriptivo del desarrollo espacio-temporal de los centros de cultivo. Enseguida, utilizando un panel de datos, se estimó un modelo de elección de sitios con el objetivo de explorar los factores determinantes de la elección de ubicación de los centros acuícolas. Los resultados del análisis sugieren la existencia de un claro patrón de desarrollo espacio-temporal de la acuicultura en Chile.
