I suppose (thinking on a more macro level than a single org's p&l) there are also opportunity costs to consider.

Arable land that would otherwise be used for (leafy greens in this example) can be repurposed for other crops, preventing further deforestation et al.

Or perhaps this land would be suitable for rewilding - Or, given that farms are likely situated at fairly convenient transit points (which may align with power transfer needs), other industries such as energy could essentially rezone these areas into solar fields.
