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.
This paper finds that, as climate change causes the geographical shift of areas suitable for growing certain crops, the potential changes in land use could have impacts on biodiversity, water resources and soil carbon storage. So-called “agriculture frontiers” - areas of land not currently suitable for producing crops but that might become suitable in future due to shifts in temperature or rainfall - cover an area nearly one-third as big as current agricultural land area.
This article in the Guardian, by food writer Bee Wilson, author of The Way We Eat Now, describes the debate around so-called ultra-processed foods. Wilson describes the classification system for processed foods developed by researcher Carlos Monteiro and the research being done on the health impacts of ultra-processed foods.
This blog post by Shefali Sharma of the Institute for Agriculture & Trade Policy says that agriculture and the people whose livelihoods depend on it must be core considerations in international climate negotiations. Sharma argues that proposed solutions such as bioenergy with carbon capture and storage (BECCS) and carbon credits simply allow existing industries to continue increasing their emissions.
UK waste charity WRAP has published guidance on compostable plastic packaging, aimed at retailers and manufacturers. The guidance covers what compostable plastics are, how they might contaminate conventional plastic recycling processes, how to label them appropriately to help people dispose of them, and six applications where compostable plastic packaging is likely to be beneficial within the UK’s current waste management infrastructure.
FCRN member ffinlo Costain has published a response to the paper Climate change: ‘no get out of jail free card’ (summarised on the FCRN website here). Costain argues that biological methane emissions - such as those from grazing livestock - can be “warming neutral” as long as they fall by 10% by 2050. Citing Oxford climate scientist Myles Allen, Costain argues that sharply cutting ruminant numbers would only deliver a warming reduction of 0.1ºC at most, which would be outweighed within a few years by continuing carbon dioxide emissions.
This review paper examines how people are increasingly using the ocean - even previously inaccessible areas - for seafood, animal feed, nutraceuticals (such as omega-3 fatty acids), fuels and minerals, shipping, waste disposal and many other purposes. It argues that the view of the ocean as being too big to be affected by humans is now outdated, and that effective governance is required to manage the ocean’s ecological health while allowing sustainable use of its resources.
This blog post, by Caroline Grunewald and Dan Blaustein-Rejto of the Breakthrough Institute (a US think tank), argues that the large scale of much American farming does not mean it is necessarily unsustainable - rather, when looking at the intensity of greenhouse gas emissions, land use and water use per unit of output, dramatic improvements have been seen since 1961.
This book outlines the latest information on how food supply chains in cities can be managed sustainably, focusing on circular economy models.
This paper assesses the rate of soil erosion in different countries, aiming to separate the effect of varying landscapes from the effect of different national territories, e.g. through different agricultural policies or management patterns. As an example of a sharp discontinuity in soil erosion between neighbouring countries, visible on satellite images, the paper shows the difference between Haiti (with a high soil erosion rate) and the Dominican Republic (with greater forest cover and a lower soil erosion rate) - two countries that would have similar natural soil erosion rates in the absence of human activity.
This podcast from global food community Food Matters Live discusses the effect that veganism has recently had on the food industry, how plant-based food and drink is likely to develop throughout 2020, and how the media and food companies talk about plant-based foods.
The European Commission has set out a European Green Deal, a plan to transform the European economy to net-zero emissions by 2050, and to decouple economic growth from resource use. The Green Deal will include a new “Farm to Fork” strategy (to be set out in full in the spring of 2020) to reward food producers for services such as storing carbon in the soil, improving water quality and reducing the use of pesticides, fertilisers and antibiotics.
This report by the European Alliance to Save Our Antibiotics assesses the antibiotics policies of ten leading British supermarkets. It finds that six out of the ten supermarkets ban their suppliers from routinely using antibiotics, with Waitrose having the most comprehensive antibiotic policies.
This paper quantifies the economic impact of herbicide resistance developed by the weed Alopecurus myosuroides (black-grass). It finds that the annual cost of this resistance is £0.4 billion each year in England, based on lost profit from lower crop yields. The global cost of herbicide resistance could be much higher, as there are 253 known herbicide-resistant weeds.
This paper argues that international measures to protect marine biodiversity should include protected areas that can move over space and time to adapt to the changing ranges of certain species, whether because the species in question are migratory, or because their ranges are changing because of climate change.
This paper used satellites to observe the effect on yield of conservation tillage practices, such as reducing soil disturbance and leaving crop residues in the field, in the United States Corn Belt. The researchers found that long-term conservation tillage (i.e. from 2008 to 2017) was associated with a 3.3% increase in maize yields and a 0.74% yield increase for soybeans.
This Guardian article discusses farms that are growing crops organically without using animal manure or blood and bone meal, in contrast to most organic farms. This approach is not yet widespread, with only around 50 such farms in the United States. Relevant organisations include the Biocyclic Vegan Standard and the Vegan Organic Network.
