摘要

摘要城市用水量会受到多种因素的影响，并可能因地区和地方的特殊性而形成不同的模式。本研究旨在利用包含 1746 个城市的数据集，确定气候、地理、人口、经济、社会和供水服务相关因素对巴西人均用水量的影响。为此，利用对数变换数据建立了多元线性回归模型。结果显示，家庭收入、水价、每户居民人数、气温、拥有洗衣机的家庭比例、城市人口、性别、拥有自来水的家庭比例以及城市的国内生产总值对城市用水量有显著影响。

Drivers of urban water consumption in Brazil: a countrywide, cross-sectional study

ABSTRACT Urban water consumption can be influenced by several factors and may have different patterns due to regional and local specificities. This research aims to determine the influence of climatic, geographic, demographic, economic, social and water-supply-service-related factors on the per capita water consumption in Brazil using a dataset with 1746 municipalities. For this purpose, a multiple linear regression model using log-transformed data was fitted. The results show that household income, water tariff, number of residents per household, temperature, percentage of households with washing machine, city population, gender, percentage of households with piped water and the municipality’s GDP significantly influence urban water consumption.

期刊介绍： Urban Water Journal provides a forum for the research and professional communities dealing with water systems in the urban environment, directly contributing to the furtherance of sustainable development. Particular emphasis is placed on the analysis of interrelationships and interactions between the individual water systems, urban water bodies and the wider environment. The Journal encourages the adoption of an integrated approach, and system''s thinking to solve the numerous problems associated with sustainable urban water management. Urban Water Journal focuses on the water-related infrastructure in the city: namely potable water supply, treatment and distribution; wastewater collection, treatment and management, and environmental return; storm drainage and urban flood management. Specific topics of interest include: network design, optimisation, management, operation and rehabilitation; novel treatment processes for water and wastewater, resource recovery, treatment plant design and optimisation as well as treatment plants as part of the integrated urban water system; demand management and water efficiency, water recycling and source control; stormwater management, urban flood risk quantification and management; monitoring, utilisation and management of urban water bodies including groundwater; water-sensitive planning and design (including analysis of interactions of the urban water cycle with city planning and green infrastructure); resilience of the urban water system, long term scenarios to manage uncertainty, system stress testing; data needs, smart metering and sensors, advanced data analytics for knowledge discovery, quantification and management of uncertainty, smart technologies for urban water systems; decision-support and informatic tools;...
