The key challenge for CRD is addressing climate change from the perspective of development: addressing the fundamental development obstacles that limit capacity for adaptation. Where development is not sustainable, especially if it is not equitable, capacity for adapting is greatly reduced-a phenomenon known as the adaptation gap . Figure 8.14 depicts the effect of development trajectories  on capacity for adaptation, a key determinant of eventual outcomes. Achieving CRD through coupling adaptation with equitable sustainable development under and low emissions profiles that limit warming to 1.5℃  is necessary to close the adaptation gap. Even if emissions are kept low and 1.5℃ emissions targets are achieved, if poverty and inequality remain high, then impacts are expected to remain high and may overwhelm capacity for adaptation. High poverty and high inequality in a society  reduce the likelihood that countries are able to manage risk and avoid residual impacts, such as also documented in the assessment above . Unsustainable development trajectories reduce capacity for adaptation and may result in highly unequally distributed residual impacts from climate change. Even despite rapid, equitable development and modest emissions reductions efforts necessary to limit warming to 2℃ , there is still risk of unequal distribution of impacts. Under all high emissions scenarios , universal residual impacts are unavoidable.
