Assessment of water footprint of vegetable crops

Abstract
Relevance. Agricultural production is the main consumer of water. Globally, about 70% of fresh water is annually used for agricultural (food and non-food) production. Nearly 40% of the world's food supply comes from irrigation. Globally, the scarcity of irrigation water due to competition between industry and urban consumption threatens food security. Future population growth, income growth and changes in nutrition are expected to increase demand for water. The rate of warming in Russia since the mid-1970s about 2.5 times the global average. The highest rate of temperature increase occurs at high latitudes. The entire territory of Russia is subject to warming, both as a whole for the year and in all seasons. Water Footprint Accounting (WF), proposed by the Water Footprint Network (WFN), has the potential to provide important information for water management, especially in water-stressed regions that rely on irrigation to meet food needs.
Methodology. The purpose of this systematic review was to collate and synthesize available data on global water use in vegetable production. Searched online databases covering the areas of environment, social sciences, public health, nutrition and agriculture: Web of Science Core Collection, Scopus, OvidSP MEDLINE, EconLit, OvidSP AGRIS, EBSCO GreenFILE, and OvidSP CAB Abstracts. The search was conducted using predefined search terms that included the concepts of "vegetable crops" and "water footprint".
Results. This article provides a brief overview of the vegetable growing water footprint and the sustainability of the blue water footprint. In general, a high green or overall (green + blue) WF may indicate that the vegetable crops are having low yields or inefficient water use. Low green and high blue WF indicate inefficient use of rainwater, which can lead to overexploitation of surface and groundwater. The water footprint can be considered a good economic ergometer, showing the level of water consumption required to obtain a certain vegetable product, whether it brings economic benefits or not, beneficial to society or not.
