Transboundary Conservation Areas, such as Parks for Peace, have been heralded for their potential to simultaneously contribute to biodiversity conservation and peace, but evidence to this effect has been elusive.  In fact, more indications suggest that transboundary conservation areas, including Parks for Peace, rely on pre-existing international peace between countries for formalization and on-going non-violent relations for continuity. Although they are primarily designed for ecological peace (based largely on arguments of ecological connectivity), they are not immune to environmental harms.  Perhaps even more challenging is how “fortress conservation” and “green securitization” compromise social peace.
