in contrast while least developed countries and small island developing states are more likely to need to improve their physical infrastructure to primarily strengthen social infrastructure landlocked developing countries need to join regional infrastructure networks as part of regional connectivity and integration and thus improve the flow of goods and services across borders for example of the million people living in the csn of the region million people still lack access to improved water sources in rural areas million people lack access to improved sanitation million people lack access to electricity and million people out of million people in csn lack access to the internet the csn therefore need to improve the availability and quality of infrastructure thus even though some countries may face greater development challenges than others they may demonstrate better infrastructure performance than countries that are naturally more advantaged
