Firstly, food price movements have played a large role in generating inflationary episodes in South Africa. Secondly, while external influences do matter, South African food price movements are mainly due to domestic influences. Th...
BACKGROUND The inverse relation between energy density (kcal/g) and energy cost (price/kcal) has been interpreted to suggest that produce (fruit, vegetables) is more expensive than snacks (cookies, chips). OBJECTIVE The objective of this study was to show the methodologic weakness of comparing energy density with energy cost. DESIGN The relation between energy density and energy cost was re...
BACKGROUND Food pricing strategies have been proposed to encourage healthy eating habits, which may in turn help stem global increases in non-communicable diseases. This systematic review of simulation studies investigates the estimated association between food pricing strategies and changes in food purchases or intakes (consumption) (objective 1); Health and disease outcomes (objective 2), and...

The results indicate that all products, except te...

Moreover, food co...
Land-use change to meet 21st-century demands for food, fuel, and fiber will depend on many interactive factors, including global policies limiting anthropogenic climate change and realized improvements in agricultural productivity. Climate-change mitigation policies will alter the decision-making environment for land management, and changes in agricultural productivity will influence cultivated...
This paper provides a theoretical and empirical examination of the forces that contribute to the long-run growth in weight over time. We argue that technological change has induced weight growth by making homeand marketproduction more sedentary and by lowering food prices through agricultural innovation. We consider how technological change creates unexpected relationships among income, food pr...
