Short summary

We assess water scarcity under various socio-economic pathways and its impact on food production in the Yellow River basin. The rapidly increasing industrial water demand will put the middle and lower reaches in a condition of water scarcity. The industrial water demand is the main contributing factor to water scarcity. Water scarcity will lead to at least 9 % reduction in food production in 2084. This suggests that a trade-offs should be considered when developing regional adaptation strategies.
