Historically, social protection has been in a constant state of transformation, dating back to the early forms of social security during the 19th century. Over the decades, social protection systems have become more complex and extensive, by taking into account diverse needs and situations within various societies across the world. With the increasing complexity of social processes and society as a whole, a number of countries started facing daunting challenges on the efficiency, effectiveness and social equity of their social protection systems. This has been more conspicuous in nations where no consistent vision and a comprehensive policy agenda were established. Moreover, numerous states have had their social protection schemes disintegrated so that various small initiatives operate in isolation rather than as part of a single unit.
