The 21st century will see the global population increase from 7.5 billion in 2017 to an expected 8.5-10 billion in 2050.
Future populations will be exposed to a range of climate change hazards of varying intensities, that will vary from place to place, with some areas or ‘hotspots’ exposed to more risks than others, compounding the challenges.
Understanding how these risks spread across regions under different climate scenarios, and who will be most exposed to what is essential to identify policy interventions and specific investments that are tailored to the regional context in order to reduce the vulnerability of the poorest and support the achievement of the sustainable development goals.
The global assessment has a threefold approach:
Diagnostic assessment of water, energy and land related risks, and how these might evolve in under different future socio-economic and climate scenarios across the globe..
Population’s exposure and vulnerability assessment to future water-energy-land risks
Identifying transformation pathways that allow countries, basins and regions to cope and reduce these risks and meet the sustainable development agenda.
Global Hotspot Analysis
This work investigates how multi-sector risks (water, energy, land) changes with higher levels of global mean temperature rise, and to what extent socioeconomic development and poverty reduction can reduce population’s vulnerability.
A fully integrated assessment modelling framework, connecting thebiophysics and economics of water, energy and land systems, was developed to address global water-energy-land challenges and elicit transformation pathways.
