DETERMINANTS OF CLIMATE CHANGE ADAPTATION AMONG FARM HOUSEHOLDS IN SOUTHWEST NIGERIA: A HECKMAN DOUBLE STAGE SELECTION APPROACH
Taofeeq A. AMUSA
Chukwuemeka U. OKOYE
Anselm A. ENETE
This study provided empirical information on determinants of climate change adaptation among farming households in Southwest Nigeria using Heckman’s double stage selection approach. Three states were randomly selected across southwest Nigeria: Ekiti, Ogun and Oyo States. Data were collected in two phases. The first phase was rapid rural appraisal of the selected states while the second phase was detailed survey using a structured questionnaire administered to 360 randomly sampled farm units. Data collected were analysed using descriptive statistics and Heckman’s double stage selection model. The result of the analysis showed that there was relatively high level of awareness of climate change among the farmers. Major sources of information about climate change among the farmers include personal observation and extension agents. From the result of the Heckman double stage selection model, variables that significantly influenced the first decision of whether or not to adapt to climate change include: gender, experience, extension visits, farm size, income, credit access, number of farm labourers and dependency ratio. On the other hand, variables that significantly influenced extent of adaptation to climate change include: gender, experience, education, extension visits, farm size, income, credit access, number of farm labourers and dependency ratio. Based on the findings, the study therefore recommends farmers’ sensitization programmes on indicators of climate most especially those indicators with low indices. Effort should be made by government at all levels towards capacity building of the farmers through improved education, extension visits, increased farm size, increase in income and improved access to credit.

TEST OF THE CATCH-UP HYPOTHESIS IN AFRICAN AGRICULTURAL GROWTH RATES
Kalu Ukpai IFEGWU
Joshua Olusegun AJETOMOBI
Babatunde Oluseyi AJIBOYE
The paper tested the catch-up hypothesis in agricultural growth rates of twenty-six African countries. Panel data used was drawn from the Food and Agricultural Organization Statistics (FAOSTAT) of the United Nations. The Data Envelopment Analysis Method for measuring productivity was used to estimate productivity growth rates. The cross-section framework consisting of sigma-convergence and beta-convergence was employed to test the catching up process. Catching up is said to exist if the value of beta is negative and significant. Since catching up does not necessarily imply narrowing of national productivity inequalities, sigma-convergence which measures inequality, was estimated for the same variables. The results showed evidence of the catch-up process, but failed to find a narrowing of productivity inequalities among countries.

EVOLUTION OF EUROPEAN GM-FREE STANDARDS: REASONING OF CONSUMERS AND STRATEGIC ADOPTION BY COMPANIES
Thomas J. VENUS
Justus H.H. WESSELER
In this article, we discuss reasoning of consumers and strategic adoption behavior of producers and retailers with respect to genetically modified-free (GM-free) quality standards in Europe. We argue that there are three major reasons why a mandatory GM labeling scheme differs from a voluntary process-based GM-free labeling scheme regarding the effect on consumer demand: (1) while both mandatory and voluntary labels signal that products containing, or produced with genetically modified organisms (GMOs) are of lower quality, experiments show that the signaling effect is stronger in the case of mandatory labels; (2) some consumers care more about the effects of consuming GMOs directly (i.e., labeled GMO) compared to consuming only products derived from GMOs (i.e., non-labeled GM-free); and (3) mandatory labeling shifts some of the labeling burden to the GM producer making the GM product relatively more expensive compared to the case of voluntary GM-free labeling. We discuss reasons why producers or retailers set or implement a voluntary GM-free production standard. To illustrate how the firm adoption theory can be extended, we use a real option game framework in a duopolistic setting and show that it can be beneficial to offer a GM-free product without labeling it. We show that this can be the case if investing without labeling works as a pre-investment or option to extend to reduce the investment cost of implementing a label in the case of an increase in demand. Finally, we provide a list of important events that have affected the evolution of the GM-free market in Europe.

PRICING ATTRIBUTES OF WINES FROM EMERGING SUPPLIERS ON THE BRITISH COLUMBIA MARKET
Veronica YOO
Wojciech J. FLORKOWSKI
Richard CAREW
We examine British Columbia (BC) wine consumers’ valuation of wine imported from emerging suppliers (Argentina, Bulgaria, Chile, Croatia and Hungary) using hedonic pricing technique. BC Liquor Distribution Branch retail sales data covering weekly sales of table wine imported into the province of British Columbia from all five countries for the period April 20th, 2002 to May 8th, 2004 are applied to estimate the influence of wine attributes on prices. The results indicate that grape variety, brand name, country of origin, and alcohol content are important factors influencing prices paid by consumers. In particular, Chilean white and red wines are associated with larger price premia as compared to Argentinean wines. Wines from Hungary, Bulgaria, and Croatia, although sold in large quantities in the BC market, are substantially discounted in comparison to New World wines. Cabernet Sauvignon fetches a higher price when blended with other varietals and Chardonnay appears to be popular and highly valued by consumers among white wines.

VALUING SOIL CONSERVATION PRACTICES USING CONTINGENT VALUATION TECHNIQUE: EVIDENCE FROM THE CENTRAL RIFT VALLEY OF ETHIOPIA
Musa H. AHMED
Kumilachew A. MELESSE
Aemro T. TEREFE
Land degradation mainly in the form of soil and nutrient depletion is the prominent problem that the Ethiopian agriculture is facing. Due to this, farmers should be aware of this problem and the necessity of implementing conservation measures. Hence, this study assesses farm households’ willingness to participate in soil conservation practice through a Contingent Valuation method in one of the most degraded parts of the country. Double Bounded Dichotomous choice with an Open-ended follow up format was used to elicit the households’ willingness to pay using data collected from randomly selected 140 sample households. Results show that the mean willingness to participate in soil conservation practices was about 25 person days per annum and the total aggregate value of soil conservation was computed to be at 975622.73 person days (24390568.3 Birr). Moreover, the Tobit regression model results indicate that the education level of the household head, initial-bid, income, labour shortage and number of days on holiday and social ceremony were important factors influencing the willingness to participate in soil conservation practices. Hence, to improve the participation level, policy should target on supporting adult education, introducing ways to increase farm income and creating awareness on the loss associated with too many days of social ceremonies.

SCALE EFFICIENCY IN EUROPEAN PORK PRODUCTION
Lukas CECHURA
Zdenka ZAKOVA KROUPOVA
Michal MALY
Heinrich HOCKMANN
The paper analyses scale efficiency in European pork production. The analysis shows significant differences in the exploitation of economies of scale among EU member states. In particular, old member states exhibit increasing returns to scale whereas most new member states show either constant or decreasing returns to scale. The differences among old and new member states are also pronounced from a dynamic perspective: whereas the old member states improved their productivity in pork production through scale efficiency, its impact in new member states was rather negative.
