Book (stand-alone)Analysis of food consumption behavior by Japanese households 2002
Also available in:
No results found.The objective of this research is to analyse the food consumption patterns and to conduct econometric analysis of the food demand structure in Japan. The study pays special attention to the question of whether or not rice is an inferior food as previous researchers have claimed and to what extent Japanese food consumption patterns have been Westernized and uses the cross-sectional household data, 1997 Annual Report on the Family Income and Expenditure Survey (FIES), compiled by the Statistics Bu reau, Management and Coordination Agency in Japan. -
DocumentEstimating Food Consumption Patterns by Reconciling Food Balance Sheets and Household Budget Surveys
dec/14
2014Also available in:
No results found.Food Balance Sheets (FBS) are one of the most important sources of data on food availability for human consumption. This paper presents a method to improve the information on food consumption patterns of FBS by using national household budget surveys (HBS). In this paper, food commodities are categorized into 16 major food groups. For each food group, the contribution to the overall caloric intake is represented in shares. Item group shares of 64 surveys from 51 low and middle income countries are compared with shares from country-specific FBS. Given the countries represented in the data, the analysis evaluates food consumption of over 3 billion persons worldwide. A model based on a cross-entropy measure of information has been developed in order to reconcile aggregate food consumption patterns suggested by FBS and HBS. The latter model accounts for the fact that data from both data sources are prone to measurement errors. Overall, the results of the reconciliation suggest that aver age consumption of cereals, eggs, fish products, pulses and vegetables are likely to be underestimated in FBS, while fruits, meat, milk and sugar products are likely to be overestimated in FBS. Even though the suggested changes in average food consumption are moderate, the results imply considerable relative changes in the aggregate consumption of single food groups. Furthermore, the results imply that the aggregate consumption of fats is 2% higher than currently assumed. The updated consumption patterns provide valuable information from an agro-industrial perspective. Differences in updated consumption pattern with respect to the original FBS might suggest a re-evaluation of FBS elements of the value chain, starting from production and ending at food losses. -
ArticleForest-based bioeconomy pathways with emerging lignocellulosic products: A modeling approach
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.The forest-based sector plays an important role in a growing bioeconomy. Long-term resource availability and allocation will be a major challenge for the bioeconomy development. Therefore, this study aims to assess how forest product markets could develop in a growing bioeconomy and which interdependencies occur between traditional and emerging forest-based subsectors. Especially, the demand for wood-based textile fibres could dynamically grow over the next decades while there might be conflicting demand for wood resources from traditional subsectors. Thus, we include dissolving pulp, lignocellulose-based textile fibres and chemical derivatives in our modelling assessment. For this purpose, we extend the product structure of a partial equilibrium model, the Global Forest Products Model (GFPM). We use an econometric approach to compute demand and trade elasticities of the emerging products. We parameterize the extended model with these elasticities and analyze three different bioeconomy scenarios. In the first scenario, the demand for woody biomass remains similar to the current pattern. In the second scenario, the use of woody biomass increases primarily to satisfy growing input demand from the energy sector. In the third scenario, biomass is increasingly used as input to produce diverse industrial and everyday products. The simulation results show that, in the third scenario, where the world is changing toward a sustainable bioeconomy, wood consumption pattern shifts away from fuelwood (-30% by 2050) and paper products (-32% by 2050) towards emerging products. In this context, the dissolving pulp subsector could outpace the continuously shrinking paper pulp subsector in 2050. For this development, the dissolving pulp subsector mainly uses released resources from the decreasing paper pulp production. Simultaneously, wood-based panels are increasingly applied (+196% by 2050) while the growth of sawnwood remains limited.
