The UK’s Department for Environment, Food and Rural Affairs has published “Health and Harmony: the future for food, farming and the environment in a Green Brexit” - a summary of the responses to its consultation.
Utilities company Veolia and plastics charity RECOUP have together released the report “Plan for plastics”, which considers how the UK can improve plastic recycling. The report finds that 93% of people think plastic bottles should be made with recycled materials and are willing to pay 2.5 pence more, on average, for a recycled bottle (compared to a non-recycled bottle). Less than 5% of plastic film is currently recycled, compared to 59% of plastic bottles.
Fishers increase their fishing activity prior to the establishment of a new marine reserve, a new paper claims. The study used satellite data to study one particular marine reserve, the Phoenix Islands Protected Area (PIPA). While fishing effort dropped to almost zero after the marine reserve was established, fishing effort prior to the reserve’s establishment was 130% higher than in a control region (where no reserve was planned).
The Trump administration has reversed a ban on using neonicotinoid pesticides (linked to declining bee populations) and genetically modified crops in over 50 national wildlife refuges (out of 560 total). Limited farming activity is permitted in some of the wildlife refuges. Previously, a blanket ban had prohibited the use of neonicotinoids and genetically modified crops in the wildlife refuges, but now decisions will be made on a case-by-case basis.
The UK’s Local Government Association (LGA) has called for industry to stop creating non-recyclable food packaging, saying that “Councils have done all they can,” to tackle the issue of plastic recycling. The LGA has found that only one-third of plastic packaging used by households can be recycled.
This paper surveys 195 cities in the United States and finds that the number of water conservation measures adopted in a city depend on both the climate (drier cities tend to have more water conservation measures than wetter cities) and political leanings (cities that lean towards the Democrats have more water conservation measures than Republican-leaning cities).
Managing tropical forest conservation on the basis of maximising carbon storage might not protect the most biodiverse regions of forest, according to a recent paper. Using datasets from Brazil, the authors found that the correlation between biodiversity and levels of carbon stored in forests depended on whether and how the forest had been disturbed by human activity.
This book, by Annoula Paschalidou, Michael Tsatiris, Kyriaki Kitikidou and Christina Papadopoulou, identifies the challenges and opportunities surrounding the conflict between food production and energy crop production.
TEEBAgriFood, part of the UN Environment initiative The Economics of Ecosystems and Biodiversity, has released a report on the environmental, health and social costs and benefits of the agriculture and food system. It finds that the food system does not keep everyone healthy or protect the environment. It calls for a reform in how we measure food system performance, because relying on yield per hectare and market prices neglects other costs such as food-borne disease and environmental degradation.
FCRN member Ben Phalan of the Universidade Federal da Bahia has written a paper discussing the strengths and limitations of the land sparing-sharing framework, which aims to allocate land use and production intensity so as to maximise the value of land for wildlife while still producing enough food for people. He notes that most studies show that wildlife would be favoured by producing food intensely on as little land as possible, and addresses some common criticisms of the model.
A report by Friends of the Earth Europe finds that plastic food packaging is not a solution to growing levels of food waste in Europe, contrary to some claims that packaging can reduce food waste by extending the shelf life of foods. For example, using packaging to group food together in larger packs could encourage customers to buy more food than necessary. Another example is that green beans are often cut to fit into the packaging, causing losses of 30 to 40%.
The European Public Health Alliance have published a study of ten EU policies on sustainable food and farming. The report finds that the policies lack a systemic perspective and are particularly weak on the health, governance and resilience aspects of sustainability. The report recommends a mix of supply- and demand-side interventions and points out the importance of considering the “food environment” when devising policies.
A report by WWF, The Rivers Trust and The Angling Trust finds that only 14% of rivers in England are classed as healthy, with damage being caused by poor farming and land management practices, for example by degraded soil being washed into watercourses and agricultural chemicals contaminating groundwater. The report sets out a strategy for managing both soil and water health, including stricter control of slurry storage, incentives for farmers to plant woodland or create wetland habitats and creating an advice service for farmers and land managers.
Better models are needed to assess and manage conflicting requirements for ecosystems services from land, a recent paper argues. These “uber integrated assessment models”, as the paper calls them, would help decision-makers to better understand the links between local and global land use policies.
The Oxford Long-Term Ecology Lab has published a map of studies published between 1990 and October 2017 that report evidence on the effects of adopting one or more sustainability standards. You can filter the map by several criteria including country, name of standard, commodity covered and research method. Topics covered include agriculture, fishing, forestry and textiles.
Scientists have unintentionally created a variant of a bacterial enzyme that is 20% better than the original at breaking down polyethylene terephthalate, commonly used to make plastic bottles. The researchers were investigating the properties of a bacterium that has naturally evolved to digest plastic.
