Meanwhile, access to infrastructure that is seen as essential for social and human development indicates even larger gaps in most developing regions. Gaps are also huge with respect to basic sanitation facilities, as evident from figure 4.9. This contrasts, quite sharply, with the current approach to infrastructure investment that looks at individual projects on acase-by-case basis to ensure that they are ‘"bankable” (assuring repayment of loans taken for such investment) and requires that all investors in such projects get adequate returns.
