- W4226361702 abstract "Moving away from subsistence farming to market-oriented agriculture and shifting from cultivation of traditional food crops to cash crops through commercialization of agriculture are seen as a way to improve food security and nutritional status of the rural households. Using case studies on vegetable production for exports in Guatemala, tobacco cultivation as a cash crop in Malawi, and commercialization of fruits and vegetables in Nepal, this chapter addresses the central question: “Is it more likely that a cash crop–growing household would be food and nutrition secure compared to households growing traditional crops?” We also discuss recent evidence from organic farming in the United States. This chapter introduces the use of Pearson's chi-square test in determining the relationship between the types of crops grown and the welfare status of farming households. We illustrate important applications of chi-square distribution: testing hypothesis about the variances, Pearson's goodness of fit, and independence between two variables. Since many variables including cash crop production and food security and nutritional status could be mutually exclusive, the simple applications of these tests for food policy analysis are discussed. Both STATA program and R program codes are given." @default.
