The UK government is not preparing well enough for the impacts of Brexit on the food sector, argues Tony Lewis, Head of Policy at the Chartered Institute of Environmental Health in a piece for the Food Research Collaboration. Lewis points out that, among other issues, introducing necessary food safety checks on imports could cause 17 miles of tailbacks along the Dover-Calais route, the resources needed to operate the border may not be ready by March 2019 (when the UK will leave the European Union), and businesses do not have enough time to adapt in the event of no deal being reached between the UK and the EU.

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.

FCRN member Ken Giller has co-authored a paper that reviews the targets and indicators used to measure the second sustainable development goal (SDG-2), i.e. the pursuit of global food security and agricultural sustainability. The paper concludes that the UN’s current set of targets and indicators for SDG-2 are not universally applicable, and proposes a revised set of indicators.

The Food and Agriculture Organisation of the United Nations has released the September 2018 version of its quarterly reports, “Crop prospects and food situation”. According to the report, 39 countries currently require external food assistance, driven by conflicts and climate-related shocks. Of those countries, 31 are in Africa, seven are in Asia, and the remaining one is Haiti. World cereal production in 2018 is estimated to be 2.4% lower than in 2017, which saw a record high.

The Food and Agricultural Organisation of the United Nations (FAO) has released the 2018 edition of its report on food security and nutrition around the world. The report give key statistics on several indicators of nutrition and explores the links between climate-related events and food security.

In a write-up of a meeting of its Business Forum, the Food Ethics Council asks whether the concept of “ethical consumerism” is adequate for addressing food system sustainability issues. The report points out that “ethical” can have many different meanings, that businesses can lack a cohesive sustainability strategy if they are too responsive to current trends on consumer concern, that focusing on consumers can neglect systemic problem, and that not all people can afford to prioritise ethical concerns when buying food. The report also offers some recommendations to businesses.

The University of Exeter’s Centre for Rural Policy Research has released the report “Changing food cultures: challenges and opportunities for UK agriculture”. The report gives an overview of how UK agriculture might be affected by future changes in the food system, such as health concerns or increases in purchases of ready-meals and snacks.

A recent paper uses data from volcanic eruptions to estimate the effects that geoengineering with sulphate aerosols would have on agricultural production. It concludes that the damage that geoengineering would do to maize, soy, rice and wheat outputs (because of reduction in sunlight reaching the crops) would have roughly the same magnitude as the benefits of the cooling it would provide.

A carbon tax applied across the whole economy, including agriculture, could put more people at risk of hunger (in terms of dietary energy availability) than climate change itself, according to a recent paper.

As global mean temperature rises due to climate change, the chance of multiple shocks in maize production occurring at the same time rises, due to greater variability in yields. The top four maize-producing countries are United States, China, Brazil, and Argentina. The chance of all four suffering a yield loss of more than 10% in the same year is presently almost zero, but rises to 6% for 2°C of warming and 87% for 4°C of warming. The study does not account for changing variability in temperature (only the increase in mean temperature), nor any gains from breeding heat-tolerant maize varieties.

This review paper reports that organic agriculture has lower yields than conventional agriculture, by 19-25% on average across all crops, according to three meta-analyses. Lower yields may be due to the lack of use of synthetic fertilisers - organic systems are often limited by low levels of nitrogen or phosphorus - and higher susceptibility to pest outbreaks. Widespread uptake of organic farming (to produce the same amounts of output as today) would probably require some conversion of natural habitats to farmland, because of this lower land-use efficiency compared to conventional agriculture - an important consideration, as the area of certified organic production has increased from 15 million ha in 2000 to 51 million ha in 2015 (although this is only 1% of agricultural land).

The European Commission's Joint Research Centre has published a new World Atlas of Desertification, which provides maps of different factors relevant to desertification such as land use, human appropriation of biological productivity, virtual water use, smallholder agriculture and livestock production.
