The nature and type of support provided by an international financial institution depends on the issues to be addressed. For example, the loan may be directed towards the construction or refurbishment of a transport link (such as railway, port/dock, road or airport), construction of housing, provision of new buildings for schools (or other educational needs such as supply of new school books or updating of the curriculum), provision of clinics, hospitals or other medical facilities or equipment, support for SMEs in a particular sector, or even the provision of food, drink or shelter in an emergency situation.
