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.

Global transboundary river basins (TRBs) cover about 47% of land surface and 52% of population. Water scarcity is driving the potential risks as a result of competition for the limited water resources in TRBs, which turns to be both of an urgent environment issue and economic/political problems. In this study, we used a water supply-demand balance approach to estimate the impact of climate change on the water scarcity occurrence likelihood (WSOL) and water scarcity potential intensity (WSPI) in TRBs at a global scale. We projected the WSOL and WSPI by applying the global hydrological models (GHMs), which were driven by the bias-corrected data of four general circulation models (GCMs) considering different scenarios of the representative concentration pathways (RCP2.6 and RCP6.0), respectively. The results indicated that the WSOL in TRBs were expected to increase between 28% (at RCP2.6) and 42% (at RCP6.0) by 2080s in comparison with those during 1981–2010. The most significant increase of WSOL were found in the countries of West Asia as well as China and North Africa. We also found that the projection of WSPI showed less consistent trends across different basins in TRBs, with variations in a range from -10% to 5% by 2080s. In general, WSPI increased in West Asia but decreased in north Asia, Europe and North America. The results highlighted that the water scarcity in TRBs would be exacerbated by climate warming, likely overwhelming the efforts of nations to collaboratively use freshwater resources of TRBs in future, and potentially preceding more water conflicts.

River systems originating from the Upper Indus Basin (UIB) are dominated by runoff from snow and glacier melt and summer monsoonal rainfall. These water resources are highly stressed as huge populations of people living in this region depend on them, including for agriculture, domestic use, and energy production. Projections suggest that the UIB region will be affected by considerable (yet poorly quantified) changes to the seasonality and composition of runoff in the future, which are likely to have considerable impacts on these supplies. Given how directly and indirectly communities and ecosystems are dependent on these resources and the growing pressure on them due to ever-increasing demands, the impacts of climate change pose considerable adaptation challenges. The strong linkages between hydroclimate, cryosphere, water resources, and human activities within the UIB suggest that a multi- and inter-disciplinary research approach integrating the social and natural/environmental sciences is critical for successful adaptation to ongoing and future hydrological and climate change. Here we use a horizon scanning technique to identify the Top 100 questions related to the most pressing knowledge gaps and research priorities in social and natural sciences on climate change and water in the UIB. These questions are on the margins of current thinking and investigation and are clustered into 14 themes, covering three overarching topics of “governance, policy, and sustainable solutions”, “socioeconomic processes and livelihoods”, and “integrated Earth System processes”. Raising awareness of these cutting-edge knowledge gaps and opportunities will hopefully encourage researchers, funding bodies, practitioners, and policy makers to address them.
