Genetic resources of halophytes and their utilization for sustainable development of russian rangelands

摘要：

It was found that arid regions of Russia occupying more than 100 million ha include dry-steppe (74.5 mln ha), semidesert (28.7 mln ha), and desert (5.6 mln ha).Due to unwise management of natural pastures and irrigated lands many have become degraded : productivity of natural pasture ecosystems has decreased 1.5 to 2-fold, 8-10 ; and valuable forage varieties have disappeared.Every year production of irrigated lands is reduced due to salinity problems, and currently 30％ of the irrigated lands are not used for agriculture due to heavy salinization and low value.
