While there is consensus that the concept of CRDPs is useful, there are major challenges in identifying, operationalising, monitoring and evaluating them . Management approaches seldom integrate across spatio-temporal scales and may be unable to address unidirectional change and extreme events . The socioeconomic complexities and implications of pursuing integrated outcomes make it difficult to evaluate synergies and trade-offs associated with different actions in local contexts through time . Case studies by Lo  of transformation in a fishing town in south China and by Gajar  on undesirable path dependencies in development trajectories in urban and rural India show that overall adaptive capacity of populations may be decreased though politicisation and entrenchment of existing inequities, severely limiting the possibilities for future adaptation. A further challenge of implementation is timely detection of tipping points and abrupt exposure events in both climate and environmental systems , which may alter the efficacy of current and planned adaptation actions, necessitating a switch to other, more transformational strategies; in such cases, re- energising food system actors' commitment to adaptation action may well be needed .
