There are nevertheless concerns regarding institutional fit: that foreign funding regimes may not map onto more recently developed administrative traditions, leading to dominance of governance models emanating from donors . Research has found multilateral donors do not prioritise vulnerable developing countries at the project selection stage and they have received smaller allocations of adaptation finance from bilateral donors than less vulnerable countries , leaving the poor vulnerable to climate impacts. The lack of climate finance flowing to LDCs and SIDs  is compounded by access issues due to the inability of domestic institutions to meet specific fiduciary standards and other access requirements, insufficient human resource support and the inflexibility of current approaches, which are biased in favour of governments and against non-traditional actors, such as local enterprise and grassroots organisations . Further, vulnerable developing countries shoulder additional financial burden, embodied in higher interest payments to service public and private debt, due to the increased cost of capital
