Use of ICE index for satellite monitoring of irrigation massifs and land condition

Background. Globally, about half of the world's crops are cultivated under irrigation, which affects the climate of the fields and can also increase the comfort of the environment for humans. The development of satellite technologies has opened up opportunities for rapid and low-cost monitoring of the Irrigation Cooling Effect (ICE). This area of research is in its infancy, which predetermines the relevance of identifying the current trend of its development.Purpose. To analyze scientific literature in the field of ICE satellite index use for irrigated lands monitoring, to identify main directions of development and research centers.Materials and methods. Information from the Scopus and RSCI databases was used as the main source of information. The case study demonstrates the relationship between ICE and NDVI for the XUAR irrigated area in the PRC.Results. Analysis of primary literature sources has shown that at present ICE is used mainly to assess the cooling effect of irrigated crop and its water consumption, the cooling effect of urban vegetation, and to assess the impact of land cover change on local and regional climate. The main research centers are scientific organizations of China and the USA, which is confirmed by the number of scientific publications and amount of their citations. A promising direction is the use of ICE for operational satellite monitoring of crops (including rain-fed crops).Conclusion. Thus, ICE can be regarded as a useful complement to the NDVI index commonly used in satellite crop monitoring, which causes the increasing use of this index in the world, especially for irrigated land monitoring.
