DFID’s aim is for its policies and programmes to be inclusive of and accessible to all people, including people with disabilities, vulnerable and those discriminated against and excluded due to gender, geography, income, age or other characteristics. This rapid desk based study provides a reference document that identifies and summarises robust evidence of the impact of non-accessible infrastructure on people with disabilities. It makes recommendations on how to incorporate the principals of universal access into all infrastructure projects. This document should be read in combination with the DFID Disability Framework “Leaving No One behind” (2014), which sets out how DFID promotes inclusion of people living with disabilities in all its programmes.
