  • Improving the sustainability of farms often incurs additional costs for farmers. These costs come from allocating land to the maintenance of the ecological processes (energy and material flows, natural population regulation) required for the agroecosystem to function. Since these costs are not recovered on the markets, farmers see a fall in profits, the financial viability of their farms is compromised, and they suffer the consequences of the environmental services they are providing. All this makes it essential to implement government policies designed to compensate farmers for their efforts. The issue of how to assess sustainability has generated widespread debate within ecological economics, specifically as to whether it is possible to place a monetary value on it and if so, how this should be done. In a previous article we showed that agrarian sustainability involves a land cost, therefore this cost can be translated into monetary values. The purpose of this study is to develop this concept in practical terms by applying it to organic farming. We calculated the land cost of agrarian sustainability (LACAS) in order to compare organic versus conventional management in olive farming, as this crop is grown extensively in Spain and other Mediterranean countries. The results show that the agro-environmental subsidy is not enough to encourage olive growers to make the conversion from conventional to organic methods, because the land cost of sustainability is not adequately offset. They also show that improving agroecosystems can allow the land to take on more functions without increasing the land cost. In our case, encouraging the multifunctionality of the land has permitted a reduction in this cost. The LACAS could be a useful tool, not only for drawing up government policies designed to support organic farming, but also for improving the sustainability of the agrarian sector.
