Abstract Developing sustainable irrigation agriculture is one of the necessary supporting conditions for global food security and maintenance of peoples livelihood. However, farmland waterlogging salinealkaline caused by irrigation exerts an effect on crop growth process and yield in direct or indirect ways, thus severely restricts agricultural productivity, and induces negative environment effects on farmland. Based on a thorough review of formation mechanism of waterlogging salinealkaline caused by irrigation, response of crop growing and soil characteristics to waterlogging salinealkaline, as well as influence of waterlogging salinealkaline on crop yield, related management measures and technology applications for treating waterlogging salinealkaline are discussed in this paper in view of drainage, wateruse, irrigation, soil, crop, and socioeconomic etc. Besides, related research topics and important contents, namely different levels of coexistence mechanism of waterlogging salinealkaline, monitoring and evaluation of waterlogging salinealkaline coexistence situation, combination and integration mode development of waterlogging salinealkaline treatment technologies, and risk analysis and evaluation of waterlogging salinealkaline damage, are proposed to meet the goal of waterlogging salinealkaline management such as “saving irrigation, reducing emission, controlling salinity and increasing efficiency” based on sustainable irrigation agriculture.
