Soil degradation threatens our ecosystem and is among the most significant problems at a global level for agricultural production, food security and sustainability. World Soil Day 2022 on December 5th aims to heighten soil awareness so ahead of this, Anne McElvoy explores changes to both rural and urban farming. Mike Collins charts the evolution of the city farm; Jim Scown considers the relationship between soils, science and literary realism in Victorian Britain; Catherine Oliver asks why a growing number of city dwellers are rising with the rooster & discovering community in chicken keeping and Peter Wright, a film director, discusses his documentary, Arcadia, which captures the magic of rural Britain and our changing views towards the land and has a soundtrack from Adrian Utley (Portishead) and Will Gregory (Goldfrapp).

Jim Scown is a New Generation Thinker and Post Graduate Researcher at Cardiff University
