Dryland agricultural environment and sustainable productivity

다국어 초록 (Multilingual Abstract)

Global climate change is expected to cause progressively increased frequency and severity of drought events, which further seriously limit plant growth and crop yields. Increasing water use effi ciency (WUE) and yield per unit rainfall are one of the most important challenges in dry land agriculture. Here, we reviewed the comprehensive technical strategies including conserving water to combine both increased agricultural productivity and resource conservation; enquiring into how crop plants respond to drought through morphological, physiological, and molecular modifi cations that occur in all plant organs; breeding for drought tolerance where there is a delineated stress environment and genotype × environment interactions are stable; eff ective conservation of rainfall and high effi ciency of use. In addition, we discussed the preponderance of biological water-saving measures, which embraces improvements in WUE and drought tolerance, by genetic improvement and physiological regulation. Sustainable agriculture would be benefi ted from modern engineering such as biological engineering, conservation tillage, and breeding technologies.
