GLOBAL WATER TRANSFER MEGAPROJECTS PLANNED OR UNDER CONSTRUCTION
Water transfer megaprojects (WTMP) are large-scale engineering interventions that aim to ensure water security for human needs by diverting water within and between catchments. Socio-economic and environmental consequences of such projects are double-faced. Due to lack of their comprehensive inventory it is impossible to understand the consequences for freshwaters and predict the scale of future modifications. In this study, a database of key characteristics (distance, volume, cost, purposes) was compiled for 60 future WTMP that are under construction or planned by 2050 and 27 existing WTMP. Our inventory shows that in future WTMP a total volume of 1,290 km3 per year would be transferred along a total distance exceeding twice the length of Earth’s equator. Future WTMP will have longer water transfer distances compared to existing with the longest total distances and total volumes in North America, Asia and Africa. Total investments in WTMP will reach more then 2,500 billion US$. Our results show that through WTMP new links in the global river network will be created, which can introduce modifications in the hydrological cycle and functioning of ecosystems.
