“…The MRIO model is a quantitative economic model with inter‐regional input–output tables as its core, which clearly reflects the direct and indirect economic linkages between different regions and production sectors (Zhong et al, 2021). The environment‐extended MRIO model can link various resources to input–output tables, thus linking different resource metabolisms to different economic sectors and reflecting the flow of virtual resources that underlie trading networks.…”

Inter‐regional trade can potentially extend the management of resources and induced ecological environmental impacts beyond a region's territory along supply chains. We combined environmental‐extended multi‐regional input–output analysis and ecosystem services value (ESV) assessment, to identify the remote connections of construction land use and the induced ecosystem services potential loss in inter‐provincial trade in China from 2007 to 2017. The findings indicated that the virtual construction land flow increased by 0.774 million ha in the eight regions of China during 2007–2017. The Northeast and the Northwest were net exporters while most of the inflow areas were in the more developed areas such as Beijing–Tianjin–Hebei and the Yangtze River Delta. The net regional flow of ecosystem service potential loss (ESPL) in China increased by 352.64 billion yuan. The spatial heterogeneity of ESV in each province led to differences in the inter‐sectoral or inter‐regional flow characteristics of ESPL from embodied construction land use. The outflow areas of ESPL were mostly located in the old industrial bases of the Northeast and Northern Coast, which sacrificed their local ecological service value to meet the development needs of Southern Coast, Southwest China and Beijing–Tianjin. The research results help to clarify ecological and environmental responsibility, improve ecological compensation mechanisms and formulate scientific policies for coordinated protection of ecosystem services.

“…A similar outcome is reported for annual crops (e.g., maize, wheat and sorghum) at a regional and global scale where developing irrigation schemes in water-scarce areas can affect water availability 33,524 . Local water availability could also be affected in several countries in South America and the Caribbean, where climate change-induced precipitation changes could result in irrigation being required for sugar crops 523 . Producing sugar crops can affect biodiversity and soil quality, e.g., reducing species abundance and increasing soil erosion risk 474,501 .…”

“…Most of the trade-offs were related to water use and efficiency (SDG 6.4) and, to a lesser extent, to biodiversity conservation (15.1). Regardless of the feedstock type and previous land use, it was generally shown that deploying large-scale bioenergy systems to meet global and national bioenergy demand can lead to unsustainable water withdrawals in the form of irrigation 523,524,540 . These trade-offs were generally reported through the nexus between land and water and its effects on biodiversity conservation (SDG 15.1) 509,514 and the sustainable use of forest (SDG 15.2) 46,516,541 .…”

In the past decades, sugarcane production in Brazil has expanded rapidly to meet increasing ethanol demand. The large majority of this expansion occurred in Sao Paulo state. We used an integrated approach considering location-specific biophysical characteristics to determine the environmental impacts of sugarcane expansion and their spatial variation in Sao Paulo state (2004)(2005)(2006)(2007)(2008)(2009)(2010)(2011)(2012)(2013)(2014)(2015). The included environmental impacts are greenhouse gas (GHG) emissions, biodiversity, soil erosion, and water quantity. All impacts were integrated into a single environmental performance index to determine trade-offs between impacts. Our results show a strong spatial variation in environmental impacts and trade-offs between them. The magnitude and direction of these impacts are mostly driven by the type of land use change and by the heterogeneity of the biophysical conditions. Areas where expansion of sugar cane has resulted in mostly negative environmental impacts are located in the center and east of the state (related to the change of shrublands, eucalyptus, and forest), while areas where sugar cane expansion has resulted in positive impacts are located in the center-west and north (related to the change of annual crops). Identifying areas with mainly positive and negative impacts enables the development of strategies to mitigate negative effects and enhance positive ones for future sugarcane expansion. 24 42 3 A carbon footprint assessment of multi-output biorefineries with international biomass supply: a case study for the Netherlands
