Desertification threatens food security and human nutrition through its impacts on agricultural productivity. The damage caused by desertification includes both direct, on-site impacts and wide-ranging indirect, off-site effects. In this study, we applied a multi-region input-output framework to estimate the direct and indirect consequences of dese...
Article
In the context of renewable energy (RE) generation, biomass resources are different to other renewable resources because they can be stored and transported. These characteristics make bioenergy a dispatchable renewable energy source. While this property is recognised as being very important in supporting the global energy transition, the potential...
Article

Disasters resulting from climate change and extreme weather events adversely impact crop and livestock production. While the direct impacts of these events on productivity are generally well known, the indirect supply-chain repercussions (spillovers) are still unclear. Here, applying an integrated modelling framework that considers economic and phy...
Article
The frequency of disasters has been increasing over the past decades, fuelled by natural phenomena and climate-related events. Policymakers require robust methodologies to assess supply-chain impacts of disasters. Input–output-based disaster approaches are able to assess such impacts; however, they rely on some assumptions, such as the fixed produc...

The COVID-19 pandemic demonstrated the vulnerability of tourism workers, but no detailed job loss figures are available that links tourism vulnerability with income inequality. This study evaluates how reduced international tourism consumption affects tourism employment and their income loss potential for 132 countries. This analysis shows that hig...
Article
Full-text available
Sustainable development depends on decoupling economic growth from resource use. The material footprint indicator accounts for environmental pressure related to a country’s final demand. It measures material use across global supply-chain networks linking production and consumption. For this reason, it has been used as an indicator for two Sustaina...
Article
Over a million plastic bottles are bought around the world every minute, 20,000 every second. While there is agreement that single-use plastics should be phased out, records of plastic pollution point in the opposite direction. Until the phasing-out of single-use plastics materialises, there is an immediate opportunity to mitigate the environmental...
Article
When deciding on a country’s future energy policy, it is essential to accurately estimate the future generation mix and technology costs, as well as future generation site locations in electricity power grids. This estimate needs to allow for changing levels of demand and increasing levels of renewable energy supply, with both having high fluctuati...

The project aims to create a quantitative modelling framework for assessing the absolute sustainability of cities. Full supply chain environmental and social impacts of urban economic activities are assessed against biophysical planetary limits as well as social foundation thresholds. This provides quantifiable information on the global impact of cities and assists city stakeholders with the design and formulation of local and international policies. City case studies will assess where interventions can be most practically, realistically and effectively implemented.
