South-to-north water transfer schemes are considered a strategic and ambitious approach to resolving water shortage problems in the north of China. This paper discusses the proposed south-to-north water transfer schemes, which would deliver water from the south of China to the water-short north of China. The three potential water transfer routes are discussed in detail, emphasizing the different water regimens of the water export and water import regions, political and institutional implications, and environmental protection. A water balance study conducted according to the principle of integrated water resources planning and management has shown that, without water transfer, the water deficit in the north of China will continue to be an obstacle to sustainable development from now to 2050. Also, the analysis on the asynchronism–synchronism for the two regions concerned has implicated the uncertainty of future water resource availability in the water transfer regions.

The previous comparative studies on watersheds were mostly based on the comparison of dispersive characteristics, which lacked systemicity and causality. We proposed a causal structure-based framework for basin comparison based on the Bayesian network (BN) and focus on the basin-scale water–energy–food–ecology (WEFE) nexus. We applied it to the Syr Darya River basin (SDB) and the Amu Darya River basin (ADB), of which poor water management caused the Aral Sea disaster. The causality of the nexus was effectively compared and universality of this framework was discussed. In terms of changes in the nexus, the sensitive factor for the water supplied to the Aral Sea changed from the agricultural development during the Soviet Union period to the disputes in the WEFE nexus after the disintegration. The water–energy contradiction of the SDB is more severe than that of the ADB, partly due to the higher upstream reservoir interception capacity. It further made management of the winter surplus water downstream of the SDB more controversial. Due to this, the water–food–ecology conflict between downstream countries may escalate and turn into a long-term chronic problem. Reducing water inflow to depressions and improving the planting structure prove beneficial to the Aral Sea ecology, and this effect of the SDB is more significant. The construction of reservoirs on the Panj River of the upstream ADB should be cautious to avoid an intense water–energy conflict such as the SDB's. It is also necessary to promote the water-saving drip irrigation and to strengthen the cooperation.
