This review paper examines how people are increasingly using the ocean - even previously inaccessible areas - for seafood, animal feed, nutraceuticals (such as omega-3 fatty acids), fuels and minerals, shipping, waste disposal and many other purposes. It argues that the view of the ocean as being too big to be affected by humans is now outdated, and that effective governance is required to manage the ocean’s ecological health while allowing sustainable use of its resources.

This blog post, by Caroline Grunewald and Dan Blaustein-Rejto of the Breakthrough Institute (a US think tank), argues that the large scale of much American farming does not mean it is necessarily unsustainable - rather, when looking at the intensity of greenhouse gas emissions, land use and water use per unit of output, dramatic improvements have been seen since 1961.

The SHARECITY project, based at Trinity College Dublin, has launched SHARE IT, a free toolkit to help food sharing initiatives worldwide document and communicate the impact of their activities on the sustainability of food systems. 

This book sets out an accessible framework for understanding the role of agriculture in sustainable development, focusing on agriculture as a complex system with many tradeoffs and synergies.

This book uses a range of case studies to explore how food and immigration influence each other in North America, focusing on borders (e.g. geopolitical or cultural), labour and identities (including changing diets).

This book outlines the latest information on how food supply chains in cities can be managed sustainably, focusing on circular economy models. 

Dairy company Arla has commissioned this report by the Institute for European Environmental Policy, which sets out a vision for how the European dairy sector can become more sustainable in the future, balancing environmental, economic and social considerations.

This report from environmental campaign group Greenpeace UK examines how chicken consumption in the UK is linked to deforestation, through production of soy for animal feed.

This report, commissioned by the UK countryside charity CPRE, assesses the current state of “county farms” - i.e. farms owned by local authorities, sometimes let out at below-market rates to assist new entrants to farming. It finds that the area of county farms has halved in the past 40 years as a result of being sold off.
