Metadata record for the manuscript: Water scarcity will constrain the formation of a world-class megalopolis in North China

Summary

This
metadata record provides details of the data supporting the claims of the
related manuscript: “Water scarcity will constrain the
formation of a world-class megalopolis in North China”.

The
data consist of 15 Excel .xlsx format data files.

The
related study investigated the water challenge the water-scarce Beijing-Tianjin-Hebei
(BTH) region faces under China’s goal of developing it into
a world-class megalopolis, and the effects of the main water
conservation measures in the region towards the goal.

Data
access

The
data generated and analysed during the related study are publicly available as part
of this data record. The 15 Excel files are listed below, along with the names
of the figures and supplementary tables from the manuscript that each file
supports in square brackets.
1-Economic growth
&Water use: This table provides the data of GDP and water use in the BTH
region and existing world-class megalopolises (2017). The data sources include
United States Geological Survey, The Great Lakes Regional Water Use Database,
Statistics of Tokyo, Eurostat, and National Bureau of Statistics of China. [Figure 1]

2-The BTH economic and
water resource conditions: This table provides the city-level data of the
economic and water resource conditions in the BTH region (2017). The data
sources include China Statistical Yearbook, Hebei Economic Yearbook, and Water
Resources Bulletin of Beijing, Tianjin, and Hebei. [Figure 2
and Supplementary Table 4]

3-Water gaps: This table
provides the data of water gaps for the BTH region to achieve the two
benchmarking goals. The data in the column of ‘Minimum water requirement’ are
from model simulation and the data in the column of ‘Average water resources’
are calculated based on official data from China Statistical Yearbook. Water
gaps are obtained by subtracting the latter from the former. [Figure 3]

4-GDP comparison: This
table provides the GDP data of the BTH region and the existing world-class
megalopolises. BTH region’s maximum GDP data are from model simulation and the
rest of the GDP data are officially released data. The data sources include
Bureau of Economic Analysis, Eurostat, Tokyo Statistical Yearbook, and China
Statistical Yearbook. [Figure 4]

5-Measure effects: This
table provides the data of the effects of the applications of water
conservation measures. The data in the column of ‘Minimum water requirement’ are
from model simulation and the data in the column of ‘The BTH annual average
water resources’ are calculated based on official data from China Statistical
Yearbook. ‘Water saved by the measures’ are obtained by subtracting the
‘minimum water requirement’ of each measure from the ‘minimum water
requirement’ of ‘No conservation measure applied’. [Figure 5]

6-Water
gaps_four-city-excluded: This table provides the data of the water gaps for the
four-city-excluded BTH region to achieve the two benchmarking goals. The data
are from model simulation, in which four cities (Handan, Xingtai, Hengshui and
Cangzhou) are excluded from the BTH region. [Figure 6]

7- Economic size : This table provides the GDP data of the BTH
region and the six world-class megalopolises (2017). The data sources include
Bureau of Economic Analysis, Eurostat, Statistics of Tokyo, National Bureau of
Statistics of China. The exchange rate between USD and CNY is based on the
averaged central parity rate of year 2017 released by the People's Bank of
China. [Supplementary Table 1]

8- Industrial structure : This table provides the data of the
industrial structure of the BTH cities (2017). The data are provided by Hebei
Provincial Bureau of Statistics and National Bureau of Statistics of China. [Supplementary Table 2]

9- Trade data : This table provides the data of the
total trade of the BTH cities with their trade partners. The data are
calculated based on inter-city input-output table of the BTH region (2012).
Total trade value is the summation of the bilateral trade amount between the
BTH cities and their trade partners. The exchange rate between USD and CNY is
based on the averaged central parity rate of year 2012 released by the People's
Bank of China. [Supplementary Table 3]

10- Indicators for
benchmarks: This table provides the data of representing indicators as criteria
for the BTH region's goal of being a world-class megalopolis in model settings.
The data are obtained from National Bureau of Statistics of China, Shanghai
Bureau of Statistics, Zhejiang provincial Bureau of Statistics, Jiangsu
provincial Bureau of Statistics, Bureau of Economic Analysis, and Great Lakes
Maritime Research Institute. [Supplementary Table 5]

11- Objective of water
use efficiency: This table provides the data of water control objective for
improving water use efficiency in the BTH region. The Data Sources include: 1)
The People’s Government of Beijing Municipality. Beijing Water Development Plan
for 'the 13th Five-Year Plan' Period, (2016-7-8). 2) Tianjin Municipal People’s
Government. Tianjin Action Plan for Dual Control of Total Water Consumption and
Intensity for ‘the 13th Five-Year Plan' Period, (2017-3-30). 3) The People’s
Government of Hebei Province. Hebei Implementation Plan for Dual Control of
Total Water Consumption and Intensity 2016-2020, (2017-3-7). [Supplementary Table 6]

12-SNWTP water use: This
table provides the data of the SNWTP water use in the water intake cities of
the BTH region (2018). The data are provided by Water Transfer Management
Office in Department of Water Resources of Hebei Province. [Supplementary Table 7]

13- Macroeconomic
parameter comparison_provincial level: This table provides the key
macroeconomic parameters at provincial
level. The data sources include Beijing Municipal Bureau of Statistics, Tianjin
Municipal Bureau of Statistics and Hebei Provincial Bureau of Statistics. [Supplementary Table 8]

14- Macroeconomic
parameter comparison_city level: This table provides the key macroeconomic
parameters at city level. The data are provided by National Bureau of
Statistics of China and Hebei Provincial Bureau of Statistics. [Supplementary Table 9]
15- Water parameter
comparison_city level: This table provides the key water use related parameters
at city level. The data are provided by Beijing Water Authority, Tianjin Water
