Water consumption patterns of 110 cities in the Yangtze River Economic Belt in 2015

Abstract

How to formulate scientific and effective water-saving policies is of great significance for the sustainable water consumption. As a country with the largest water consumption in the world, China has been committed to formulating scientific and effective water-saving policies. However, due to geospatial variations of water consumption in different regions, how to formulate targeted and efficient water-saving policies which suit for different local characteristics has always been a key issue to be solved. In a quest to understand the water consumption patterns, this study first adopted a dual evaluation index system combining Gini coefficient and Global Moran’s Index to classify different types of water consumption. Taking 110 cities in the Yangtze River Economic Belt as research objects, the water consumption of 110 cities was divided into nine types. According to each type, a targeted water-saving policy is given. This study provides important theoretical support for the efficient management of water resources in the Yangtze River Economic Belt, and provides reference for water resources management in other regions at the same time.

Dynamic Evaluation of Water Resources Management Performance in the Yangtze River Economic Belt

“…China is a large developing country with a serious shortage of water resources, with per capita water resources accounting for only one-quarter of the world average [4]. Water resources are not being used efficiently, the effective utilization coefficient of farmland irrigation water is low, industrial water consumption is 2-3 times greater than the global level, and the leakage rate of the urban water supply network is as high as 20% [5].…”

Consumption Pattern Analysis of Water Consumption For Commercial Connections in Davao City

“…Water consumption has two separated meanings: 1) The relatively narrow understanding, which refers to the amount of water resources that evaporate and infiltrate in an irreparable loss. 2) The widely understood concept of water consumption which refers to the actual water usage at a certain period of time for a specific production activity (Sun & Li, 2022). The concept of water consumption used in this study refers to the latter.…”
