| Building on the results of an initial analysis of risk ranking data collected from a representative group of some 850 Canadian respondents in early 2003, this study assesses a similar set of risk ranking questions applied to a somewhat larger representative group of some 1500 Canadians in late 2005. We also compare the 2003 and 2005 risk rankings. In both surveys, risk rankings for eight food safety issues (bacteria contamination, pesticide residuals, use of hormones in food production, use of antibiotics in food production, BSE (mad cow disease), food additives, use of genetic modification/engineering in food production, fat and cholesterol in food) and six environmental safety issues (water pollution by chemical run-offs from agriculture, soil... |

| This paper analyses time allocations of a sample of farmers, from four southwest counties in China that are representative of the poor areas of the country. The allocations of time toward two different activities - farming and non-paid domestic work - are modeled as semi-logarithmic input demand models. Plowland areas and demographic variables are significant explanators of these time allocations, but this is not the case for the economic variables of prices and wage rates. The results suggest the existence of inefficiencies in the markets for products and for labour. It is concluded that sound market systems for inputs and outputs are crucial to poverty reduction and development in poor areas of China. |

| This project applies statistical models to analyse the relative importance ratings for selected food risk issues given in January 2003 by a representative cross-Canada sample of consumers. Ratings for environmental risks that may be associated with agriculture are also assessed. Results of ordered probit econometric models that analyze the influence of respondent's socio-economic and demographic characteristics on food and environmental risk ratings indicate that these are influenced by gender, age, income, employment and location of residence. Males tended to choose lower risk ratings; residents of Quebec tended to give higher risk ratings to most of the queried food and environmental safety issues. The results suggest that measures of trust in... |

| This thesis gives the overview of concept and constitution of the closed supply chain of green agricultural products on logistics center, and the necessity of regarding logistics center as core enterprises. Meanwhile, it analyzes the function of logistic center of agricultural products, namely functions of exchange, collection, distribution, storage and transportation. It also poses the prerequisites of logistics center. The logistics center of agricultural products must have stable profit expectancy, prominent scale, strong appealing power, capacity of bearing market risk and basic thoughts of supply chain management. The functional design of the closed supply chain of green agricultural products has been discussed in 5 aspects, namely logistics center,... |

| Close supply chain of green agricultural products is defined, consisting of the supplier, manufacturer, distributor, retailer and consumer (customer). Cost structure of distributor is analyzed, mainly including the order activity-based cost, the inventory cost and the supply transportation cost of agricultural products in upstream and downstream enterprises. Based on this, conceptual model of the close supply chain of green agricultural products is established. According to the idea of dynamic planning, optimization model of close supply chain of green agricultural products at four stages is also set up. In other words, under the constraint condition of supply chain and the uncertainty of sales volume, optimization of the sum of inventory cost, supply... |
