Title
UNESCO - Sustainable Water Management: Problems and Solutions under Water Scarcity

Abstract
By analyzing the contradiction between water resource shortages and the demands for green land irrigation, this paper presents an optimization measure of irrigation scheduling, under various rainfall conditions, to improve irrigation efficiency of green land. 9 kinds of meadow treatment plots were used to study the effects of different sunken depths as well as the optimal proportion between rain harvesting surfaces and meadow plots. Based on the research, an optimization measure was calculated using the Crop Water Indictor and this was put forward as a useful reference for urban water saving.
