Current crop production levels could feed a population of 9.7 billion people in 2050, according to a recent paper, but only in a future in which there are socio-economic changes, significant shifts in diets towards plant-based foods, and limited biofuel production. Without dietary changes, crop production would have to increase by 119% by 2050.

Irish social enterprise foodture has produced a podcast about food citizenship, featuring Anna Cura of the Food Ethics Council. Anna describes the concept of food citizenship as being a mindset where people to think about themselves as engaged citizens, not just consumers, when making food purchase choices.

The Centre for Ecoliteracy, a Californian non-profit, has produced a free interactive guide to understanding food and climate change, covering both how climate change affects the food system and how the food system contributes to climate change.

The US divisions of Danone, Mars, Nestle and Unilever have established the new Sustainable Food Policy Alliance, hoping to influence policymakers and regulators in five key areas: product transparency, nutrition, the environment, food safety and a positive workplace for food and agriculture workers. According to the Washington Post, the new alliance supports the reduction of salt in packaged foods and the introduction of “nutrition facts panels” to highlight sugar and calorie information (read more here).

This book, by Klaus Lorenz and Rattan Lal, discusses the present state of knowledge on soil carbon dynamics in different types of agricultural systems, including croplands, grasslands, wetlands and agroforestry systems. It also discusses bioenergy and biochar.

The UK’s Committee on Climate Change has released its 2018 Progress Report to Parliament on Reducing UK Emissions. Chapter 6 focuses on agriculture and land use, land-use change and forestry. The report finds the UK agricultural emissions were unchanged between 2008 and 2016. In 2017, half of farmers did not think it was important to consider emissions when making decisions about farming practices. The forestry sector’s ability to sequester carbon has levelled off due to the average age of trees increasing relative to the past. Chapter 6 makes only passing reference to demand-side measures for agricultural emissions reductions (see Figure 6.9).

The UK’s Food Research Collaboration initiative has released a briefing paper on the differences in animal welfare standards between the UK and its likely post-Brexit trading partners, such as the fact that antibiotic use in cattle is nine to sixteen times higher in the US than the UK, by weight of cattle. The report points out that welfare standards risk being weakened to help obtain trade deals, and recommends several measures to protect animal welfare after Brexit, including farmer subsidies for higher welfare standards, mandatory labelling to help consumers choose better welfare standards, and using public procurement policies to promote higher welfare.

The UK’s Eating Better alliance has published a survey of ready meals in the main UK supermarkets. The briefing reports that only 3% of the 1350 ready meals surveyed were entirely plant-based; vegetarian, plant-based and meat substitute meals altogether made up 14% of the meals surveyed; 77% of the meals contained meat; and 10% contained fish or seafood. Some retailers sell vegan and vegetarian ready meals at a higher price than other meals, most notably Tesco’s Wicked Kitchen vegan range, which is 67% more expensive than Tesco’s regular range. Nearly one third of meat-based meals did not specify the country of origin of the meat, while only three retailers included the meat in their own-brand ready meals under their farm animal welfare policies.

A recent paper assesses the carbon implications of converting Indonesian rainforests to oil palm monocultures, rubber monocultures or rubber agroforestry systems (known as “jungle rubber”). It finds that carbon losses are greatest from oil palm plantations and lowest from jungle rubber systems, in all cases being mainly from loss of aboveground carbon stocks. The paper points out that, “Thorough assessments of land-use impacts on resources such as biodiversity, nutrients, and water must complement this synthesis on C but are still not available.”
