Food Availability and Access in Lesser-Industrialized Societies: A Test and Interpretation of Neo-Malthusian and Technoecological Theories

Population pressure and human adaptation to food security demands through technology have been a dominant concern of researchers and policymakers alike in international development. This paper examines neo-Malthusian and technoecological determinants of food security in lesser-industrialized societies between 1970 and 1990 using an OLS regression of food security change. Findings reveal that population pressure and overurbanization concerns are indeed valid for food availability, having negative implications, while adaptive measures such as the application of fertilizer technologies, land-use intensification, infrastructural development, and the internationalization of food markets help balance these negative effects. Interestingly, such technological improvements operate net of increased food availability and economic growth. Thus, Green Revolution technologies and the internationalization of global food systems have confronted population pressure in the developing world. However, findings are less conclusive for food access, indicating that improvement in availability does not necessarily translate into meeting distribution needs, thus challenging the ability of these two theories to comprehensively explain the complexities of food security. Questions therefore remain with regard to future food security concerns.     

Work in unemployment - occupied or preoccupied? A review

This review explores the literature on the concept of work in unemployment and its relationship to health. A range of literature about the activities of unemployed people is reviewed and discussed with reference to three questions: What do unemployed people do?, What activities are associated with the health of unemployed people? and Do unemployed people work? From the literature, two groups of unemployed people are described: those who are characterised by active patterns of activity and those characterised by passive patterns. It is argued that the active group is psychologically healthier than the passive group. Concepts of work in both groups of unemployed individuals are presented, arguing that the active group seeks to replace employment with other work activities and that the passive group are engaged in work also, but that this presents as fret and preoccupation about their situation. These concepts of work are presented in the context of three major theoretical models of the personal impact of unemployment. Finally, implications for practice and directions for future research are suggested.
