Agriculture land use right transfer (ALURT) is a new policy designed to meet the demand of the sustainable development of agriculture in China. In the Heihe river basin (HRB), ALURT has also recently been introduced to cope with the emerging challenges in agriculture. In this paper, we empirically study the long-term viability of this new policy in HRB using a sustainability assessment. We collect the documents of ALURT contracts, statistical data of ALURT performance, and conduct interviews with its users. The main finding is that the centralized institutional structure of ALURT in HRB compromises its long-term viability. In particular, the power imbalance under the regulation of the intermediate agency, which causes the dissatisfaction of the participants, is threatening the application of the ALURT policy in the long run. Therefore, we suggest that the role of the intermediate agency in ALURT needs to be redefined, to better serve the sustainable development of agriculture in HRB.

“…This was achieved by allocating a reasonable water quota and introducing additional water costs to the farmers. The second was upgrading the economic activities through industrial transformation [27,28,37]. The government had been promoting a highly value-added industry, as well as a secondary industry (e.g., manufacturing) and a tertiary industry (e.g., service industry).…”

“…We estimated the total available water was 2.25 to 2.5 billion m 3 annually based on Gansu Water Resource Bulletin [6,28], of which 85% was river water and 15% was groundwater [27]. The water consumption of Zhangye was 2.39 billion m 3 in 2010 and agriculture accounted for 94% of the consumption [29].…”

Assessment of Downscaling Planetary Boundaries to Semi-Arid Ecosystems with a Local Perception: A Case Study in the Middle Reaches of Heihe River

Abstract:The middle reaches of Heihe River are located in the oasis of the Gobi Desert where limited freshwater supply supports more than 1.5 million inhabitants. The intense agricultural activities are depleting the groundwater reserve. Consequently, natural landscapes and habitats are degraded. Though such development improves the livelihood of the local community, long-term sustainability of the ecosystem is at risk. Local authorities must be informed holistically to prepare for adapting to the changes and/or mitigating the impacts. The purpose of this study was to perform a regional sustainability assessment based on downscaling the planetary boundaries (PBs). We proposed a regional safe operating space framework that applied a top-down approach using the environmental monitoring data, and a bottom-up approach using knowledge from the local perception about environmental disaster. We conducted on-site samplings and interviews of residents to demonstrate the method. Overall, we showed that the middle reaches had transgressed the safe operating space, particularly on the freshwater use and biogeochemical flow dimensions. We found that the local perception acquired from interviews complemented the insufficiency of the monitoring data and provided the insightful social implications of transgressing the safe operating space, i.e., the anticipated impacts on local livelihood, for policy support.

“…The water consumption ratios are calculated for both human and nature, while only the results for human are shown in the plots as the consumption ratio of nature equals to one minus the consumption ratio of human. Here, we only consider the agriculture water use as the water use for human, since the sum of domestic and industry water use is less than 5% of the total human water use in the entire HRB (Cheng et al, 2014;Li et al, 2015;Wang et al, 2009). Moreover, the 25 domestic and industry water use is irrelevant to green water and blue water interactions, since almost all of the return water of domestic and industry water abstraction flows back into the river channel through pipes causing no exchanges between green and blue water (Vanham et al, 2018).…”

Abstract. Water resources assessment is crucial for human well-being and ecosystem's health. Assessments by considering both the blue and green water are of great significance as the green water plays a critical but often ignored role in the terrestrial ecosystem, especially in arid and semi-arid regions. Many approaches have been developed for green and blue 10 water valuation, while few of them considers the interrelationship between them. This study proposed a new framework for green and blue water assessment by considering the interactions between them in an arid endorheic river basin where hydrological cycling is dramatically altered by human activities. Results show that even though the green water is the dominant water resources, the blue water is also critical. Most of the blue water are transformed to green water through physically and human induced processes to meet the water demand of ecosystems. Time and spatial variability of water 15 supply and consumption forms totally different blue and green water regimes in different ecosystems. We also found that human use an increasing share of water with the decrease of the water availability. The massive water use by human reduces the water use for natural ecosystems. This indicates that natural ecosystems will take a higher risk of freshwater use when the water use competition increases. This study provides crucial information to better understand the interactions between green and blue water by assessing water resources in an explicit way. It also provides crucial implications for water 20 management aiming to make the balance between humankind and nature.
