“…According to Bin Rahman and Zhang [4], rice consumption accounts for over 80% of all irrigated freshwater resources in Asia, hence, boosting grain productivity whilst saving water is a big challenge for rice cultivation. Unfortunately, the natural resources required for agricultural production, namely water and land/soil, are non-tangible and therefore exhaustible, especially when they are poorly managed due to the negative effects of climate change and population growth [5][6][7][8][9]. Therefore, rice farming currently faces certain problems, such as water scarcity, degradation of water and soil quality, degradation of soil fertility, etc.…”

In the face of the negative impacts of climate change and the accelerated growth of the global population, precision irrigation is important to conserve water resources, improve rice productivity and promote overall efficient rice cultivation, as rice is a rather water-intensive crop than other crops. For several decades, various water conserving technologies have been studied in order to significantly increase water use efficiency (WUE). The objective of this paper is to review the main technologies and approaches for assessing the water requirements of rice crop in order to contribute to water saving in irrigated rice production, after clarifying the performance indicators of the irrigated systems. Several scientific articles from previous studies were consulted and analyzed. These studies showed that irrigation water conservation includes a wide range of practices, staring from the crop irrigation water requirements assessment to the implementation of the water saving practices on the field. In addition, irrigation water conservation technologies could be categorized into three groups, namely water-conserving irrigation systems, water-saving irrigation methods, and water-conserving agronomic practices. The influence of the individual and combined irrigation water use efficiency tools was highlighted. This paper will enable researchers to acquire knowledge on water-saving methods for estimating the rice crop water requirements and thus allow them to effectively contribute to improve the performance of irrigated rice cultivation systems using various water conservation technologies.
