Horse farms are a unique land use, situated at the intersection of the rural and the urban, in a perfect position to contribute to efforts of sustainability and multifunctionality and provide functional open spaces in the urban fringe. Despite this, they are poorly tracked and planned for by most government bodies, from local to national. This thesis synthesizes existing literature to examine how horse farms can contribute to the goals of sustainability and multifunctionality and how they are currently managed in planning. The author then makes proposals as to how they can be better managed in the future; the most effective and simplest method to implement in managing horse farms is likely to be overlay zones, adjusted to suit the needs and scales of the horse industry in the particular community.
