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. -

No results found.The 2011 FAO assessment of global food losses and waste estimated that each year, one-third of all food produced in the world for human consumption never reached the consumer’s table. This not only means a missed opportunity for the economy and food security, but also a waste of all the natural resources used for growing, processing, packaging, transporting and marketing food. Through an extensive literature search, the 2011 assessment of food wastage volumes gathered weight ratios of food losse s and waste for different regions of the world, different commodity groups and different steps of the supply chain. These ratios were applied to regional food mass flows of FAO’s Food Balance Sheets for the year 2007. Food wastage arises at all stages of the food supply chains for a variety of reasons that are very much dependent on the local conditions within each country. At a global level, a pattern is clearly visible; in high income regions, volumes of wasted food are higher in the processin g, distribution and consumption stages, whereas in low-income countries, food losses occur in the production and postharvesting phases. -
ArticleNon-timber forest products – A key tool to improve food security and nutrition in the drylands of Africa

No results found.Desertification and climate change will reduce the provision of ecosystem services in African drylands, including losses in biodiversity and soil fertility. With a major part of the population in these areas relying heavily on natural resources for survival, this worsens a health situation that is already ridden by hunger & malnutrition. Tree Aid works in Africa’s drylands to unlock the potential of trees to tackle poverty and food security while improving the environment. In particular, the promotion of non-timber forest products (NTFPs) can improve the health of rural populations by enhancing food security and nutrition. Here, we present a quantitative study that explores the impacts of promoting the production and consumption of NTFPs among 33,212 households in four regions of Burkina Faso, which feature the highest malnutrition rates in the country. This project was a partnership between Tree Aid and the Swiss Development Agency and ran from January 2017 to December 2020. Its socioeconomic and nutritional impacts were evaluated with baseline & endline assessments using the Rural Household Multi Indicator Survey1 (RHoMIS), a well-established household survey tool designed to analyse farm systems, a nutritional survey using SMART technology (Standardized Monitoring and Assessment of Relief and Transitions2 ) & focus group discussions. We find that enhancing access of women and vulnerable groups to wild & cultivated NTFPs through nutrition gardens & raising awareness of their nutritional value improves the food and nutritional security of the project rural households. Overall, the 263% increase in the proportion of calories sourced from key NTFPs (shea and baobab), which tripled daily intake per person, contributed to an 8% reduction in the number of households below the calorie line and a 42% reduction in chronic malnutrition in under 5-year-olds. These results reinforce the case for protecting & regenerating forests, which bring significant benefits to human health for rural population across the Sahel.
