Writing in the Guardian, Isabella Tree of Knepp Castle Estate argues that vegan diets ignore the potential of wildlife-friendly livestock grazing methods. Tree claims that not using anti-worming agents or antibiotics allows cow dung to feed various soil organisms, contributing to soil restoration and wildlife diversity.

This book, by Shelley Koch, looks at how gender intersects with the different stages of the food supply chain.

This book, edited by Subramanian Senthilkannan Muthu, examines the development and implementation of a variety of indicators of sustainability for the food system.

The Global Partnership on Forest and Landscape Restoration’s report “Restoring forests and landscapes: the key to a sustainable future” presents case studies of the successful restoration of landscapes that have been affected by deforestation and land degradation.

New Zealand’s Parliamentary Commissioner for the Environment has released a report exploring how much and over what timescale the climate is affected by methane emissions from livestock. It focused on two questions. First,if methane emissions from livestock were held at current levels or followed business-as-usual trajectories, what would their contribution to future warming be? Second, what reduction in methane emissions from livestock would be needed so that they cause no additional contribution to warming?

The World Wildlife Fund has released a report measuring on-farm crop waste at various locations in the United States. During the 2017-18 growing season, 40% of tomatoes, 39% of peaches, 2% of potatoes and 56% of romaine lettuce were left in the field. Causes of waste at the farm stage include strict quality standards, damage due to weather, variable consumption patterns and unpredictable labour supply. Some growers pointed out, however, that the nutrients in on-farm waste food are almost always recycled, e.g. as animal feed or by ploughing the waste back into the field.

14.4 million households don’t currently spend enough on food to follow the UK’s Eatwell Guide recommendations for a healthy diet, according to a report released by the UK-based Food Foundation. The report estimates that a household of two adults and two children (aged 10 and 15) would have to spend £103.17 per week to follow the Eatwell Guide. To meet the Eatwell Guide recommendations, the poorest 50% of households would have to spend around 30% of their disposable income (after tax and housing costs), while the richest 50% of households would have to spend around 12% of their disposable income.

A new paper reviews the extent to which sustainable intensification has been achieved in England. It concludes that agricultural intensification drove environmental degradation during the 1980s. In the 1990s, however, yields became decoupled from fertiliser and pesticide use, meaning that some ecosystems services began to recover. The authors interpret their results as meaning that sustainable intensification has begun. Farmland biodiversity, however, has not recovered.

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).
