Integrated climate change actions or responses can be inefficient and infeasible in the absence of enabling conditions, including the policy conditions that reinforce unified climate action, and sustainable financial mechanisms for implementation of the programmes and policies . In the absence of strong coordination, integrating mitigation and adaptation may undermine the overall or individual objectives of either climate response . A lack of coordination in mitigation and adaptation may also exacerbate the threats of climate change to sustainable development . Therefore, for successful integration of CRD, it is necessary to move beyond considering either adaptation or mitigation towards better understanding the linkages between adaptation and mitigation projects and policies at multiple levels of governance to identify potential trade-offs in projects and policies  and to identify the enabling conditions for designing and implementing action leading to synergies .
