Multilayer Network Clarifies Prevailing Water Consumption Telecouplings in the United States

Abstract

By facilitating the distribution of potable water and subsequent collection of wastewater for treatment (Giustolisi et al., 2019;Krueger et al., 2017;Möderl et al., 2011), engineered water-related networks (e.g., water distribution and collection systems) are central to city functioning.Engineered water-related networks involve real or physical transfers of water and therefore tend to cover local (municipal or city) to regional spatial scales. However, human-water interactions span beyond those

Exploring The Spatial Structure of Interregional Supply Chain: A Multilayer Network Approach

“…The intermediate flow matrix records the economic exchanges among 17 sectors and 34 provinces in Indonesia, reflecting their intricate economic relationships (e.g., supply and demand) as well as their interdependence and mutual constraints. A multilayer network is defined as 𝑀𝑀 = (𝐺𝐺, C) [9][10][11]. 𝐺𝐺 is a set of weighted directed graphs representing each economic sector layer, 𝐺𝐺 = �𝐺𝐺 𝛼𝛼 ; 𝛼𝛼 ∈ {1, … , 𝑘𝑘}�.…”

The Application of PPGIS to Telecoupling Research: A Case Study of the Agricultural Landscape Transformation in an Indigenous Village in Taiwan

“…The telecoupling framework is applied in fields related to sustainable science to explore the coupling relationship between nature and human beings involved in various topics, including agriculture and agro-food systems [19][20][21][22], fish and animal husbandry [23,24], water resources [25,26], tourism [27,28], energy and minerals [29,30], environmental governance and ecosystem services [1,[31][32][33], and environmental justice [34]. There has also been progress in the development of methodologies for telecoupling research.…”

Domestic Groundwater Depletion Supports China's Full Supply Chains

“…As groundwater resources underpin both national supply chains and global trade (Gumidyala et al., 2020), the connection between agricultural trade and groundwater depletion has been recently highlighted (Dalin et al., 2017, 2019; Marston et al., 2015). Much research has focused on quantifying total or surface water use embedded in sectoral products within or across countries/regions (Garcia et al., 2021; Richter et al., 2020; Vanham et al., 2018), but less attention has been paid to the role of groundwater withdrawals and related sustainability of the supply chains (Dalin et al., 2019). We do not have a good understanding of how groundwater (and groundwater depletion) is incorporated along the full supply chain of a nation, including industrial products, services, and final consumption.…”
