Farmers are challenged to reconcile the demand for environmental goods, food security, and the viability of rural societies, by negotiating price volatility, land use drivers, climate change, and demographic issues. Alongside such challenges, a new, widely discussed concept of farm resilience has emerged. The triangle of sustainability, resilience, and risk enables the basis to be set for a conceptual framework of Good Agricultural and Environmental Conditions (GAEC). Herewith, it is demonstrated how the proportions of this triangle change; reasons for the implementation of GAEC as sustainability standards for EU farms are analysed. Firstly, ways in which its principles have evolved over the past two and a half decades are investigated. The question of whether and how the GAEC framework reflects its own starting points linked to sustainability, risk, and resilience is also examined. These have evolved into something different, due to success having created new economic actors, seeking more complex, open economic, and political institutions than those provided by a state-centric model of development.
