But the uneven distribution over space and time and often limited transferability make resources scarce in specific regions in specific periods. The global megatrends are also not manifesting themselves equally across the globe: population growth and income growth are projected to vary widely between OECD and non-OECD countries, climate change impacts primarily affect countries in Asia and Africa, etcetera. Therefore, tensions are more manifest on a disaggregated level. This calls for an analysis at a disaggregated level.
