While the equine sector in Sweden and Norway provides leisure activities, entertainment and employment for many people of all ages, these come with associated negative effects. Studies of the environmental impacts caused by the sector show that nutrient leakage from manure piles, paddocks and pastures is a problem, alongside issues of feed and transport. Agents within the sector have been cast as potential threats to the environment, rather than as carriers of solutions. We want to change this. The ultimate purpose of the project is to spearhead a pro-environmental transformation of the equine sector. In collaboration with riding schools, federations and higher education institutions, this inquiry aims to gain a deep understanding of the decision-making processes and actions taken by individual and collective actors, as these are crucial for a lasting change to occur. This transformation will strengthen the sector's capacity to operate as a positive force for societal change.
