The measurement of food consumption and expenditure is a fundamental component of any analysis of poverty and food security, and hence the importance and timeliness of devoting attention to the topic cannot be overemphasized as the international development community confronts the challenges of monitoring progress in implementing the 2030 Agenda for Sustainable Development. In 2014, the International Household Survey Network published a desk review of the reliability and relevance of survey questions as included in 100 household surveys from low- and middle-income countries. The report was presented in March 2014 at the forty-fifth session of the United Nations Statistical Commission (UNSC), in a seminar organized by the Inter-Agency and Expert Group on Food Security, Agricultural and Rural Statistics (IAEG-AG). The assessment painted a bleak picture in terms of heterogeneity in survey design and overall relevance and reliability of the data being collected. On the positive side, it pointed to many areas in which even marginal changes to survey and questionnaire design could lead to a significant increase in reliability and consequently, great improvements in measurement accuracy. The report, which sparked a lot of interest from development partners and UNSC member countries, prompted IAEG-AG to pursue this area of work with the ultimate objective of developing, validating, and promoting scalable standards for the measurement of food consumption in household surveys. The work started with an expert workshop that took place in Rome in November 2014. Successive versions of the guidelines were drafted and discussed at various IAEG-AG meetings, and in another expert workshop organized in November 2016 in Rome. The guidelines were put together by a joint FAO-World Bank team, with inputs and comments received from representatives of national statistical offices, international organizations, survey practitioners, academics, and experts in different disciplines (statistics, economics, nutrition, food security, and analysis). A list of the main contributors is included in the acknowledgment section. In December 2017 a draft of the guidelines was circulated to 148 National Statistical Offices from low- to high-income countries for comments. The document was revised following that consultation and submitted to UNSC, which endorsed it at its forty-ninth session in March 2018 (under item 3(j) of the agenda, agricultural and rural statistics. The version presented here reflects what was endorsed by the Commission, edited for language. The process received support from the Global Strategy for Agricultural and Rural Statistics. The document is intended to be a reference document for National Statistical Offices, survey practitioners, and national and international agencies designing household surveys that involve the collection of food consumption and expenditure data.

This meeting report is an outcome of the WHO-UNICEF Technical Expert Advisory Group on Nutrition Monitoring (TEAM), which was supported by the Bill & Melinda Gates Foundation. The goal of the consultation was to promote increased communication, coordination and collaboration for the purpose of accelerating progress towards identifying or developing a parsimonious set of metrics for global monitoring of healthy diets for individuals over 2 years of age. Eighty-five participants took part in the consultation, representing a wide range of institutions and roles in the data value chain.

The most complete review of human nutrition, ideal for those looking for a deeper grounding in the subject before pursuing a career in the discipline.

Telescoping errors occur if survey respondents misdate consumption or expenditure episodes by including events from outside the reference period in their recall. Concern about telescoping influenced the design of early Living Standards Measurement Study (LSMS) surveys, which used a two-visit interview format to allow a bounded recall. This design fell out of favor although not for evidence-based reasons. Recent guidelines to harmonize food data collection in low- and middle-income countries by using one-week recall increase the relevance of telescoping because errors spread over a shorter period will loom larger. To provide evidence on telescoping, we conducted a survey experiment in Ethiopia, randomly assigning a balanced sample – either a two-visit bounded recall or a single visit unbounded recall. The average value of reported food consumption is 16 percent higher in the unbounded single visit recall relative to the two-visit bounded recall. Put differently, in this experiment, telescoping errors amount, on average, to an entire extra day worth of consumption being included in the report for the last seven days. Most of the error is explained by difference in reporting of spending on less frequently consumed, protein-rich foods, so apparent diet diversity and dietary quality indicators are likely to be overstated when using unbounded recall.

This book offers an essential, comprehensive, yet accessible reference of contemporary food security discourse and guides readers through the steps required for food security analysis. Food insecurity is a major obstacle to development and achievement of the Sustainable Development Goals. It is a complex issue that cuts across traditional sectors in government and disciplines in academia. Understanding how multiple elements cause and influence food security is essential for policymakers, practitioners and scholars. This book demonstrates how evaluation can integrate the four elements of food security (availability, access, nutrition and resilience) and offers practical tools for policy and programme impact assessment to support evidence-based planning. Aimed at researchers, postgraduates and those undertaking professional development in food studies, agricultural economics, rural development, nutrition and public health, the book is key reading for those seeking to understand evidence-based food security analysis.

This book aims to contribute the knowledge and understanding of nutritional impact of food systems. Focus is also be given to food systems elements status identification, policy analysis to examine potential effects of different policy options throughout the food system, in particular policies in agriculture, food marketing and trade, social protection, gender, Foreign Direct Investment (FDI) on food industry, nutrition, and environment and education etc. Good practice and lessons learnt to strengthen the beneficiary countries’ evidence-base for addressing nutrition related challenges from the food system perspective.
