The Relationship

The rapid urbanization and industrialization of China in recent years has presented serious challenges for the country in guaranteeing the preservation of agricultural water resources. This study selected four areas in China, each with different water resource and social development conditions. The relationship between the processes of urbanization and industrialization and recent agricultural water use was analyzed using rates of urbanization and the proportion of the added values from secondary and tertiary industries to China's gross domestic product. The analysis showed that overall agricultural water use in China decreases as the processes of urbanization and industrialization proceed. Agricultural water use has decreased in the Huang-Huai-Hai and northwest regions because both have experienced water resource shortages. The impact of industrialization and urbanization is minor in the northeast and southern regions as these areas have abundant water resources; however, the proportion of agricultural water use to total water use has decreased. These results reflect the impact that urbanization and industrialization have on agricultural water use, particularly in terms of how these processes change population structure, industry structure, and comparative benefit. This study advocates for a synergistic development of industrialization, urbanization, and agricultural modernization, and the guarantee of grain safety in China.

Improving agricultural water use efficiency (AWUE) is an important way to solve the shortage of water resources in arid and semi-arid regions. This study used the Super-DEA (data envelopment analysis) to measure the AWUE of 52 cities in Northwest China from 2000 to 2018. Based on spatial and temporal perspectives, it applied Exploratory Spatial Data Analysis (ESDA) to explore the dynamic evolution and regional differences of AWUE. A spatial econometric model was then used to analyze the main factors that influence the AWUE in Northwest China. The results showed firstly that the overall AWUE in Northwest China from 2000 to 2018 presented a steady upward trend. However, only a few cities achieved effective agricultural water usage by 2018, and the differences among cities were obvious. Secondly, AWUE showed an obvious spatial autocorrelation in Northwest China and showed significant high–high and low–low agglomeration characteristics. Thirdly, economic growth, urbanization development, and effective irrigation have significant, positive effects on AWUE, while per capita water resource has a significant, negative influence. Finally, when improving the AWUE in arid and semi-arid regions, plans should be formulated according to local conditions. The results of this study can provide new ideas on the study of AWUE in arid and semi-arid regions and provide references for the formulation of regional agricultural water resource utilization policies as well.

Efficient Water Use

Agricultural water is the largest water user in Yantai City, and its water consumption accounts for more than 2/3 of the total water consumption in Yantai City. The potential for agricultural water saving is huge, but the overall level of agricultural water efficiency in Yantai City is not very high, and the waste of water resources is serious. Efficient agricultural water use in Yantai is a key issue for achieving efficient and sustainable use of water resources in Yantai. Different regions in the study area have different social and economic developments, different industrial structures, and different natural climates, and their investments in agricultural water conservancy facilities are also different. In order to better study the agricultural efficient water use model in Yantai City. This article will divide the agricultural irrigation sub-area according to the actual situation of Yantai.

Use Efficiency

The increasing shortage of water resources and the growing demand for crops make water use efficiency a decisive factor for the sustainable and healthy development of the agricultural system. In order to evaluate agricultural water use efficiency from the water footprint perspective, the current study constructed the comprehensive water efficiency (CWE) index based on eight single agricultural water use efficiency performance parameters. The water resources utilization and efficiency in the wheat production system of China from 2006 to 2015 were analyzed and the sensitivity of single indices for CWE was identified. The results show that the national crop water footprint (CWF) for wheat production was estimated to be, including 46.3% blue, 36.6% green and 17.0% blue components, respectively. The spatial distribution patterns of water use efficiency performance indices were different. CWE of the country was 0.387, showing an upward trend over time and decreased from the southeast to the northwest geographically. Crop water productivity (CWP), productive water ratio (PWR) and rainwater consumption ratio (RCR) turned out to be the first three sensitive parameters for CWE in China. The improvement of China’s overall CWE relied on reducing inefficient blue-green water use and increasing the output capacity for per unit water. Advanced agricultural water-saving technologies were in high need for goal achievement, especially for the Huang-Huai-Hai plain, which held more than 70% of Chinese wheat production and CWF. The results provide support for efficient utilization and sustainable development of water resources in the agricultural system.

Agricultural Water Use

Based on the concept of agricultural total factor efficiency and the concept of total factor energy efficiency, this paper uses the DEA model based on input method to measure the total factor water resource efficiency. In the process of calculation, some factors of production, such as GDP, labor force and so on, are considered in order to make up the traditional method for the deficiency of considering single factor of water resources. This paper calculates the total factor water resources efficiency in 31 provinces of China in the year of 2009 and 2012, and analyses the spatial distribution and the change of water resources efficiency. The results indicate that the absolute number and relative proportion of agricultural water use are important influence factors of water resources efficiency.

Resource Shortage

With the quickening of the process of industrialization and urbanization, industry and urban water consumption rising increased the demand for agricultural water resource. Water pollution brought by industrialization and urbanization reduces the water supply. In the freshwater resources under the condition of the total supply shortage, Shandong agricultural water will face greater pressure. So various and effective measures must be taken to ease the contradiction between supply and demand of agricultural water resources.
