Significant public expenditure on adapting to climate change is taking place through national budgets in some of the world’s poorest countries.  In Ethiopia and Uganda, the overwhelming majority of this expenditure is being funded domestically.  International support to assist such countries adapt to climate change, as called for under the UNFCCC, has not been forthcoming at the scale necessary.  International support should, at a minimum, match the level of domestic public spending relevant to climate change in the most vulnerable countries.
