“…In agricultural production sectors such as dairy, olives, rain-fed farms, and rice, the agricultural green development efficiency has been widely recorded (Meul et al, 2007;Basset-Mens et al, 2009;Picazo-Tadeo et al, 2011;Gómez-Limón et al, 2012;Saber et al, 2021). Some scholars started from agricultural nitrogen efficiency (Godinot et al, 2016), agricultural water use efficiency (Todorovic et al, 2016;Akram and Mendelsohn, 2017), agricultural machinery efficiency (Hillesheim and Luxem, 2018), and other aspects to discuss the promotion mechanism of agricultural green development efficiency. In recent years, the research perspective of agricultural green development has tended to be diversified.…”

Green development of agriculture is important for achieving coordinated and high-quality regional development for China. Using provincial data from 1990 to 2020, this work explored the dynamics of agricultural green development efficiency of 31 provinces in China, its spatiotemporal characteristics, and its driving factors using a super-efficiency slacks-based measure (Super-SBM), the Malmquist productivity index (MPI), spatial autocorrelation, and a geographic detector. Results showed that the overall agricultural green development efficiency showed a U-shaped trend, suggesting a low level of efficiency. Although a gradient difference was visible among eastern, central, and western regions, the efficiency gap narrowed each year. Technological progress and efficiency both promoted agricultural green development efficiency, especially technological progress. Agricultural green development efficiency had significant spatial aggregation characteristics, but Moran's I result showed a downward trend from 2015 to 2020, indicating a risk of spatial dispersion in the later stage. The provinces with high agricultural green development efficiency were mainly concentrated in the eastern region, while those with low efficiency were concentrated in the central and western regions. Agricultural green development efficiency was influenced by various factors, which showed differences according to time and region. The impact of the labor force's education level and technological progress increased during the study period, and significantly facilitated agricultural green development efficiency in the eastern region, while the central and western regions were still affected by the scale level and environmental regulation, reflecting the advantages of the eastern region in terms of economy and technology. In the future, strengthening agricultural scientific and technological innovation and deepening interprovincial cooperation can help further improve the level of green agricultural development. In addition, local governments should formulate more precise local agricultural support policies based on macro-level policies and local conditions.

“…There are also scholars who look at the impact of ecological issues, such as loss of biodiversity, on food security in the context of ecological security issues [ 37 ]. Scholars have also explored the promoting mechanism of agricultural green development efficiency from the aspects of agricultural nitrogen efficiency [ 38 ] and agricultural water efficiency [ 39 ]. Wang et al measured the agricultural eco-efficiency and the level of food security in 31 provinces in China, then they studied the coupled and coordinated relationship and spatial correlation between the two, which showed that agricultural eco-efficiency and food security were spatially positively correlated, with the positive spillover effect gradually increasing [ 40 ].…”

“…Aiming at efficient utilization of water resources in irrigation areas, conventional research has mainly covered optimization design for vertical and cross sections of canals [1,2], optimal layout of a canal system [3], water allocation optimization of a canal system [4], and optimal allocation of water resources for irrigation areas including canals and field crops [5,6]. Also there is some relevant research focused on heat preservation for lining canals in alpine areas [7,8].…”

The mathematical model of optimal water quantity allocation for a single main canal in a large-scale irrigation area was constructed that took the minimal sum of the squared deviation of water shortage for water receiving areas controlled by the single main canal in one given irrigation period as the study target, and the total irrigation quantity of the single main canal as a constraint condition. Taking the optimal allocation of water quantity of each branch canal as decision variables, and several branch canals under the irrigation sequence of the main canal as a state variable, this model was solved by the one-dimensional dynamic programming (DP) method, by which the minimal water shortage and corresponding optimal water quantity allocation of each branch canal was calculated. The proposed method could provide a decision-making reference for optimal water resources allocation of single main canal irrigation areas, and also provide the theoretical basis for optimal water quantity allocation of a main canal with rotation irrigation by strips or with segmented rotation irrigation mode in China’s large-scale irrigation areas. Taking Hengliu Main Canal of Zhouqiao Irrigation Area in Jiangsu Province as a study case, optimization results showed that in a medium drought year (p = 75%) and a special drought year (p = 95%), minimal water shortage for water receiving areas controlled by Hengliu Main Canal was respectively 2.57 × 104 m3 and 23.31 × 104 m3 during the ponding period of rice. The corresponding water quantity allocation for each branch canal has reflected a compellent model solution precision and efficiency.
