TLDR
The Yellow River basin is a key food production centre of global importance facing rapidly growing water scarcity as mentioned in this paper, and the challenge will be to switch to improved water demand management, which is hampered by existing governance structures, and lack of integrated agriculture and water resource policies.Abstract:
The Yellow River basin is a key food production centre of global importance facing rapidly growing water scarcity. Water availability for agriculture in the basin is threatened by rapid growth in the demand for industrial and urban water, the need to flush sediment from the river's lower reaches, environmental demands and growing water pollution. Climate change is already evident in the basin with long-term declines in river runoff, higher temperatures, and increasing frequency and intensity of drought. The Chinese government has exhausted most options for improving water supply. The challenge will be to switch to improved water demand management, which is hampered by existing governance structures, and lack of integrated agriculture and water resource policies.read more

Sensitivity and uncertainty in crop water footprint accounting: a case study for the Yellow River Basin
TL;DR: In this article, a grid-based daily water balance model at a 5 by 5 arc minute resolution was applied to compute green and blue water footprints of the four crops in the Yellow River Basin in the period considered.
Journal ArticleDOI
Natural and anthropogenic influences on the recent droughts in Yellow River Basin, China.
TL;DR: The results revealed that the duration of precipitation's dry spells was important for agricultural drought duration, whereas hydrological drought severity and duration highly depended on soil moisture.
Journal ArticleDOI
Food security and sustainable resource management
TL;DR: The potential adverse environmental impacts of increased agricultural production include unsustainable depletion of water and soil resources, major changes in the global nitrogen and phosphorous cycles, human health problems related to excessive nutrient and pesticide use, and loss of habitats that contribute to agricultural productivity as discussed by the authors.
Journal ArticleDOI
Water scarcity in the Yellow River Basin under future climate change and human activities.
TL;DR: The results suggest that the average WUAR under both RCP4.5 and RCP8.5 will likely exceed the water scarcity threshold (WUAR >20%) and will reach up to 39.9 and 44.7%, respectively.
