Showing results for: Food chain stage
The food chain describes the physical flow of goods from agriculture through processing and distribution, to retailing to eventual consumption and waste disposal. The papers and reports in this category highlight the different issues and impacts associated with each particular stage of the food chain.
13% of the UK population is now vegetarian or vegan, while a further 21% identify as “flexitarian”, according to the 2018-19 edition of the Food and Drink Report by supermarket chain Waitrose & Partners. Among other food trends, the report also discusses plastic packaging, claiming that 88% of survey participants who had watched the final episode of the wildlife documentary Blue Planet II have changed how they use plastic.
According to a survey of US beer drinkers, 59% would be willing to pay more for beer that has been brewed using more sustainable processes, such as energy efficiency or carbon saving measures. On average, respondents were willing to pay $0.22 more per 12-ounce bottle than the price they already paid for their favourite beer ($1.69 per 12-ounce bottle).
Researchers have called for governments to phase out organophosphate pesticides in agriculture, ban their non-agricultural uses, and take steps to reduce human exposure to organophosphates. The researchers’ argument is based on systematic reviews that link foetal organophosphate exposure to adverse effects on the development of children’s brain and nervous system.
A case of bovine spongiform encephalopathy (BSE), also known as “mad cow disease”, has been confirmed on a farm in Aberdeenshire. The case was discovered before entering the human food chain, and Rural Affairs Minister Mairi Gougeon has said that all necessary measures have been taken to protect consumers.
Two commentary pieces question the findings of the study “Association of Frequency of Organic Food Consumption With Cancer Risk”, which claims that higher organic food consumption is associated with a lower risk of cancer. The pieces point out that only two cancer types showed a statistically significant reduction in risk, and that the reduction in cancer risk only appeared to hold true for older women, not men, younger adults or people with a high overall quality of diet.
The book “Organic Food and Farming in China: Top-down and Bottom-up Ecological Initiatives”, by Steffanie Scott, Zhenzhong Si, Theresa Schumilas and Aijuan Chen, examines the development of the organic food sector in China and its influences from both the state and grassroots actors.
This report from the UK’s Agriculture and Horticulture Development Board reviews how the behaviour of farmers might be influenced so that the recommendations of researchers and policymakers can be implemented on farms.
The global agricultural system doesn’t produce enough fruit, vegetables and protein to meet the nutritional needs of the world’s population, according to this paper. Meanwhile, grains, fats and sugars are overproduced, relative to what is needed for a healthy diet (defined in this paper as a diet in accordance with the Harvard Healthy Eating Plate (HHEP)).
The book “Feeding the world: Brazil’s transformation into a modern agricultural economy”, by Herbert S. Klein and Francisco Vidal Luna, examines the development of Brazil’s agricultural production, provides a historical understanding of the changes in Brazil’s economy, and explains Brazil’s impact on the world food system.
Losses of wheat, rice and maize to insects could increase by 10 to 25% per degree Celsius of climate warming, according to this paper. This is due to two main factors: insects have faster metabolisms at higher temperatures and therefore need to eat more; and insect population growth rates will also change with temperature.
A paper reviews how “working lands” such as farms, forests and rangelands can be managed to protect biodiversity and ecosystems services. The paper points out that the management of working lands can be complementary to using protected areas to conserve biodiversity.
California agritech startup Iron Ox has unveiled an “autonomous farm”, where robots move plants and transplant them from one stage to the next. Artificial intelligence controls pests and diseases and adjusts growing conditions. The farm is not entirely automated, as humans still sow seedlings and package the harvested crops. The farm produces leafy greens and herbs.
A quarter of survey respondents claim that healthy and nutritious food in the UK is too expensive, while 10 million people live in “food deserts”, according to a report by London-based think tank the Social Market Foundation. The report examined three barriers to healthy eating: prices, affordability (relative to income) and access to food stores.
A paper argues that current definitions of ultra-processed foods are inconsistently applied. Furthermore, while higher consumption of ultra-processed foods is associated with higher sugar intake and lower fibre intake, the paper claims that intakes of fat, saturated fat and salt are not associated with ultra-processed food consumption. The paper questions the policy recommendation that ultra-processed foods should be avoided.
The book “Changing the food game: market transformation strategies for sustainable agriculture”, written by Lucas Simons, discusses how markets can be changed to support a sustainable food system. Chapter topics include how food production impacts the world, market failures, and phases of market transformation.
