However, incomplete historical data on the magnitude and frequency of eruptions worldwide and the difficulties associated with up-scaling computationally intensive volcanic ash dispersal models have limited regional or global scale assessments (100 s km).
While global scale assessments are important, the global scale dynamics need to be connected to local realities and vice versa.
Our results suggest that regional to global scale assessments of flooded landscapes and wetlands that do not involve issues requiring 1 m resolution per se may be addressed with acceptable accuracy by applying SMA techniques to low resolution imagery.
Based on integrated modeling of biomass production and land use, Kraxner et al. (2013) presented an example of global scale assessments for bioenergy production under deforestation, land-use change, and other climate effective aspects to focus on policy design and its implementation.
Döll, P. Vulnerability to the impact of climate change on renewable groundwater resources: a global-scale assessment.
Examples of these metrics include the water stress indicator for global-scale assessment [45], the criticality ratio for country-scale assessment [46], and the Water Supply Stress Index (WaSSI) for a hydrologic basin scale [47].
The impact of debris cover has not yet been taken into account in regional- or global-scale assessments of glacier mass balances and freshwater resources by using physically based numerical models.
It is challenging to develop global-scale assessments of organic matter in oceans, as they include inactive pools stored in sediments and fossil deposits and bioactive reservoirs such as dissolved CO2 and H2CO3, marine organisms that differ markedly in rates of turnover and hence influence on atmospheric C inventories [23].
More explict consideration of standardized conservation prioritization procedures and global scale species assessment data by state agencies reviewing the species on their lists as well as cooperative multi-state planning could be useful in gaining highest conservation efficacy in each state.
Results suggest that a few key indicators could be used when evaluating a country's overall development status during continental and global scale sustainability assessments.
The global scale and self-assessment scales are developed based on the four subsets of scales, with a broader purpose of serving different users of the listening ability scales, such as policy makers and self-learners. 1. Descriptor collection .
