“…Uncontrolled water wastage and numerous water pollution incidents have made the problems of water shortage and degradation more serious, which has led to a huge negative impact on social and economic development [17][18][19]. Therefore, improving water efficiency and reducing water pollution are crucial for sustainable water use [20][21][22][23].…”

Since water stress and industrial water pollution pose a huge threat to South Korea's sustainable water use, it is an urgent task to assess industrial water green use efficiency (GUEIW). Based on the global non-radial directional distance function (GNDDF) model, this paper calculated GUEIW in 16 Korean local governments from 2006 to 2015 using two decomposition indicators: Economic efficiency of industrial water use (ECEIW) and environmental efficiency of industrial water use (ENEIW). The growth of GUEIW is mainly driven by ECEIW, and subsequent environmental problems are obstacles to achieving green use of Korean industrial water. The regional heterogeneity of GUEIW is so important that the downstream region outperformed the upstream region in all three indicators. The government's efforts to ensure water quality inhibits industrial development in upstream areas, where incomes are much lower than in downstream areas, and downstream industrial areas have to pay upstream industrial areas extra for water. However, regarding upstream industrial areas, low prices easily promote water waste. Because of relatively high water use costs, downstream producers are encouraged to save water. To improve the economic efficiency of industrial water use in upstream areas, advanced water technology should be developed or introduced to make full use of water resources in industrial production. Keywords: water resource; South Korean urban industry; green use efficiency of industrial water (GUEIW); global non-radial directional distance function model (GNDDF); economic efficiency of industrial water use (ECEIW); environmental efficiency of industrial water use (ENEIW)

“…upstream farmers in Zimbabwe may forgo some water abstractions to benefit Mozambique's downstream hydropower production). The practical implementation of such trade-offs might be possible by using compensation payments , while another approach is to consider trade-offs between efficiency and equity by using a multi-objective optimization (Hu et al, 2016). However, as this may be institu- tionally and politically complicated, decision makers might be interested in knowing the impacts on the planned projects if one or several countries do not cooperate.…”

“…China has only 7% of the world's cultivated land resources, but provide food for one-fifth of the world's population [7]. As a major agricultural country, China's agricultural water consumption accounts for more than 60% of total water consumption, of which irrigation water accounts for more than 90% of total agricultural water use [8][9][10]. With the rapid development of industrialization and urbanization in China, the trend of agricultural land and water resources being occupied is difficult to reverse, and the country's food security faces enormous challenges [2,11,12].…”

Agricultural water and land resources are key elements of human production and their unbalanced distribution has threatened the sustainable development of agriculture and regional food security. This study is aiming to investigate the spatial-temporal changes of matching characteristics between agricultural water and land resources in Ningxia during 2007 to 2017. The agricultural irrigation water (AIW), farmland area (FA) and effective irrigated area (EIA) were selected as quantity parameters for agricultural water and land resource. Results show that the gravity centers of AIW and EIA both moved in the southeast direction, while the gravity center of FA moved northwestward, which indicated a better spatial matching degree between AIW and EIA. According to the Gini coefficient and total spatial mismatch index, the spatial mismatch between AIW and FA of Ningxia was remedied and that of AIW and EIA was worse. Counties with sufficient and insufficient AIW were distributed in the north and the south of Ningxia, respectively. The sensitivity of agricultural irrigation water to land resources remarkably increased in the study period, particularly for the counties in northern area of Ningxia. The findings may provide implications for effective management of regional agricultural water and land resources.
