Water Allocation and Integrative Management of Precision Irrigation: A Systematic Review

Precision irrigation, defined as an efficient water allocation technique characterized by the optimal management and best collaboration of various factors of the irrigation process, attracts considerable attention in agricultural production and crop cultivation. This paper reviews the latest research developments in water allocation mechanism and integrative management effectiveness of precision irrigation, and highlights how irrigation water allocation and integrative management contribute to the high-efficiency performance of precision irrigation techniques; the irrigation models, irrigation infrastructure, and management strategies currently being used are emphasized. Thereafter, the future development prospects in water allocation and integrative management could be systematically analyzed and subsequently explored. Some frontier techniques such as data-oriented irrigation management, performance-proven water allocation, and cloud-based irrigation control are among the critical technologies capable of building a sustainable, integrative, and evolutionary irrigation system while providing the higher quality and efficiency needed for a full application of precision irrigation. This review could be used as an effective reference to study the complicated correlations between precision irrigation and its constructive influences in different environmental conditions, and to facilitate the practical promotion of irrigation productivity with higher accuracy and increased reliability of returns.

Optimization Of Irrigation Water Allocation Using Linier Programs (Case Study Batu Bulan Dam Irrigation)

The area of the Batu Bulan dam is less than 183 hectares with a capacity of 15 liters per second, the largest dam on the island of Sumbawa, located in Batu Bulan village, Moyo Hulu sub-district, Sumbawa regency, West Nusa Tenggara. Batu Bulan Dam is planned to be able to meet the irrigation needs, raw water, and has a potential for hydroelectric power plants. Considering the latter plans and the limited water supply from the dam, it is necessary to have a study for the optimization of the Dam's water allocation. By this study, the water allocation can be optimized and the planting patterns are managed. This is the objective of this research, namely the optimization of Batu Bulan Dam waters allocation for irrigation utilization, which is expected to improve dam operation patterns, to obtain the best cropping patterns and to obtain optimum benefits of rice and corn plants planted in the irrigation area. One method that can be used to solve the water allocation problem is linear programming with the objective is maximizing total profits and the constraints is water availability and land area.
