Financing for development is an approach adopted to help countries achieve the Millennium Development Goals of ending poverty. However, the MDGs were narrow in scope and overlooked issues like gender inequality. The Sustainable Development Goals replacing the MDGs in 2016 aim to end poverty and inequality through 2030. The SDGs target both developed and developing countries collectively. While resources exist globally to finance development, they are not always effectively mobilized or channeled for this purpose. Domestic resource mobilization, such as through taxes, is the largest source of funds available to developing countries and strengthening this capacity is key to achieving the SDGs.
