The book “Food and sustainability”, edited by Paul Behrens, Thijs Bosker and David Ehrhardt, is a textbook that addresses food sustainability from a multidisciplinary perspective.
The book “Farm to Fingers: The culture and politics of food in contemporary India”, edited by Kiranmayi Bhushi, explores diverse viewpoints on current food issues in India, including food security, global policies, and the impact of food bloggers.
WWF-UK has produced a report that maps multi-stakeholder initiatives in the food system by commodities, geographies, issues and stakeholders involved. The report is aimed at helping initiatives identify the gaps where they can make a unique contribution.
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.
This upcoming book, edited by Atanu Sarkar, Suman Ranjan Sensharma and Gary W. vanLoon, brings together examples of technological solutions and governance frameworks for sustainable 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.
This book, by Ramesh Ray and S Ramachandran, presents technological interventions in ethanol production from food crops, addresses food security issues arising from bioethanol production and identifies development bottlenecks.
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.
Disruptions to supplies of food-grade CO2 in Europe are causing shortages of carbonated drinks, meat and crumpets, and could threaten animal welfare. Gasworld explains that several European CO2 plants have prolonged their periods of maintenance downtime due to low CO2 prices (read more here).
A new paper reviews evidence on agricultural intensification in low- and middle-income countries and concludes that intensification rarely leads to both environmental and social benefits. Only 17% of the case studies were found to have win-win outcomes. The paper finds that the two outcome categories most frequently reported in the literature are food production and income, and that these outcomes are the most likely to be positive (at 52% and 68%, respectively). Other outcomes, such as for various ecosystems service indicators, are less frequently reported and are less likely to have positive outcomes.
