The significance of considering both green and blue water in water resources assessment is that green water plays a critical role in terrestrial ecosystems, especially in arid and semi-arid regions. The interaction between green and blue water is crucial in the overall water cycling process. Human activities have dramatically altered the hydrological cycling in an arid endorheic river basin, leading to the transformation of blue water into green water to meet the water demand of ecosystems.<\/p>\n
How does water availability affect the competition between humans and natural ecosystems?<\/h3>\n
As water availability decreases, humans tend to use an increasing share of the water, reducing the water available for natural ecosystems. This poses a higher risk of freshwater use for natural ecosystems when there is competition for water between human and nature. Approximately 38.6% of the vegetation-covered area, mainly farmland and forest, may face a moderate or high risk of increased conflict and tension over freshwater.<\/p>\n
What are the implications of the new framework for water management strategies?<\/h3>\n
The new framework for water assessment, which considers all important factors related to water supply and consumption, goes beyond traditional water balance assessments. It provides crucial information for understanding the interactions between green and blue water and offers implications for water management to achieve a balance between humankind and nature. Water management strategies need to consider the interconnection between green and blue water and the relationship between humans and nature to ensure sustainable water use.<\/p>\n
What is the Heihe River Basin and why was it chosen as a study area?<\/h3>\n
The Heihe River Basin is located in the central part of Eurasia and is characterized by a dry climate, rare precipitation, strong winds, and ample solar radiation. It is heavily impacted by human activities and suffers from water scarcity. The basin has significant north-south differences in climate, with precipitation decreasing from east to west in the Qilian Mountains in the south. The Heihe River Basin was chosen as the study area because it is located in an arid region with limited water resources. It is heavily impacted by human activities, which have dramatically altered hydrological cycling. The basin has strong groundwater and surface water exchanges that influence the interactions between green and blue water.<\/p>\n
What methods were used in the study to assess green and blue water resources in the Heihe River Basin?<\/h3>\n
The study used the Soil and Water Assessment Tool (SWAT) model to simulate the green and blue water flow in the basin. The model divided the basin into multiple sub-basins and hydrological response units (HRUs) based on land use, soil, and slope classes. The model was calibrated and validated using observed data to ensure accuracy. The spatial and temporal distribution of green and blue water flow in different ecosystems was analyzed using the model.<\/p>\n
What are the ecosystem services provided by green and blue water flows in the Heihe River Basin?<\/h3>\n
The green and blue water flows in the Heihe River Basin provide various ecosystem services. Green water flow is critical for terrestrial ecosystems, especially in arid and semi-arid regions, as it supports vegetation growth and provides habitats for wildlife. It helps maintain biodiversity, regulate the water cycle, and prevent soil erosion. Blue water flow is important for meeting the water demand of ecosystems, sustaining aquatic habitats, and supporting the functioning of rivers and wetlands. The interaction between green and blue water flows contributes to the overall resilience and health of the ecosystem.<\/p>\n
