As a coastal city, Accra is vulnerable to the impacts of climate change and sea level rise, with population growth putting increasing pressure on the coastal areas. Drainage infrastructure is particularly at risk, which has profound implications for people's livelihoods, especially in informal settlements. Inadequate planning regulation and law enforcement, as well as perceived corruption in government processes, lack of communication across government departments and lack of concern or government co-ordination with respect to building codes are major impediments to progressing the development of Accra's drainage infrastructure, according to the Climate & Development Knowledge Network.
