A review of global research on private investment in the water sector

摘要

This study critically examines the evidence on private-sector water investment over the past 24 years. It provides a basis on which future research can consider how global water investment issues can be better addressed. Moreover, this study exhibits scenarios of water investment performance that can potentially help investors make better investment decisions. Overall, we find that the water sector is expanding, and the market appears to be resistant to economic forces, suggesting that private investors can obtain positive returns.
