It is therefore crucial to the reduction of poverty and inequality, the strengthening of human capabilities and the realization of human rights, the enjoyment of which has long been enshrined in international human rights treaties (see Box 3.1). For example, realizing the right to health requires not only accessible and affordable health services but also the availability of food, water and sanitation, clothing and housing, access to quality education, and protection from risk and contingencies such as maternity, illness or work-related accidents through adequate social security. The CESCR has also clarified that the realization of these rights depends on the accessibility, affordability, acceptability and quality of related social services as well as on the adequacy of transfer payments such as pensions, family allowances or unemployment benefits.
