Showing results for: Consumption and production trends
The 2019 edition of the Global Agricultural Productivity Report from Virginia Tech University emphasises the systemic nature of the many challenges facing food, health and environment and calls for increased agricultural productivity as a way of meeting future food demand sustainably.
This discussion paper from the Food Research Collaboration examines “food hubs”, which it defines as “entities that sit between people who produce food and people who use it”, and asks what they are, what they are for and why we need them.
FCRN member Anna Birgitte Milford of the NIBIO (Norwegian Institute of Bioeconomy Research) has co-authored this paper, which studies the impact of various variables on meat total meat and ruminant meat consumption levels (both total and ruminant) in 137 countries. The paper assesses factors which had previously not been used together in similar analyses, including economic, cultural and natural factors (e.g. land availability and climate).
This paper models the greenhouse gas (GHG) emissions and water footprints of both baseline consumption patterns and nine different healthy diets that prioritise plant ingredients for 140 countries. The authors find large differences in GHG and water footprints between countries, with vegan, two-thirds vegan or “low food chain” (including insects, molluscs and forage fish) diets generally leading to the greatest footprint reductions.
FCRN member Gesa Biermann of Ludwig-Maximilians-University Munich has co-authored this paper, which analyses trends on a popular German recipe website, finding annual growth rates of 16% in vegetarian recipes and 3.5% in vegan recipes between 2005 and 2018.
College students who take a course on food and the environment reduce their reported ruminant meat consumption by 28% relative to their consumption prior to the course, according to this paper by FCRN member Jennifer Jay of UCLA Civil and Environmental Engineering.
According to this randomised controlled trial, people eat an average of 500 kcal more per day when offered ultra-processed food compared to unprocessed food (as defined by the NOVA system). Furthermore, the trial subjects gained weight on the ultra-processed diet and lost weight on the unprocessed diet.
This policy briefing from EU food waste research project REFRESH outlines policy options for reducing food waste at the consumer level, based on both desktop research and a survey of households in four countries.
In this paper, FCRN members Christian Reynolds and Tom Quested review the effectiveness of different consumption-stage measures to reduce food waste. Examples of successful interventions include serving food on smaller plates (which can reduce food waste by up to 57%) and changing school nutritional guidelines (which reduced waste of vegetables by 28% because fewer students selected vegetables and those who did select vegetables ate more of them).
This report from the Japanese Institute for Global Environmental Strategies shows how lifestyles would have to change in industrialised countries and some industrialising countries in order to meet climate change targets.
The UK’s Department for Work and Pensions will introduce a new measure of food insecurity, reports the Guardian. The new measure will be based on ten questions about food purchase and consumption patterns in the annual Family Resources Survey, which surveys around 20,000 households each year.
This book, by Mark Gibson, gives a broad overview of the development of the food industry and drivers of food supply, including information on food waste, genetic modification, food safety, politics and social trends.
