Percentage change in the value of land from land degradation (based on the Haberl and Imhoff models, data found in Appendix 3) The Great or perhaps not so Great Transitions are underway

The Scenarios Individualism Community Focus on Well-being

Characterizing the Scenarios
(Note: This is only from land cover change Not from land degradation) This table shows the 12 scenarios that were combined from 3 different sources to make the four future scenarios used in this paper. It also shows the characteristics and variable of these four scenarios.

Percent Change in ES Values
Global map showing the scale of percent change for each country in ecosystem services value in each of the four scenarios from the 2011 base map.
21
Asia & Oceania The terrestrial values for the ecosystem services in 47 countries in Asia and Oceania for the 2011 base and each of the four future scenarios, including the percent change for all four scenarios.
22
Temporal Modeling Total values out to 2050
This graph shows the total values for each scenario through 2050 when both the unit values and land areas are changed.

China The biome land use changes for four scenarios compared to 2011 ecosystem services values. First Column: Maps of the land cover of each biome for the base map and the four scenarios. Second Column: Maps of the pixels changed between the base map of 2011 and each of the four scenarios. In the MF and FW maps, there are multiple symmetric circular desert areas. These occur because a single desert pixel in the original base map grew symmetrically outwards from all edges of desert. Third Column: Maps of the change in the value of ecosystem services between the base map of 2011 and each of the four scenarios.

SE Asia The biome land use changes for four scenarios compared to 2011 ecosystem services values. First Column: Maps of the land cover of each biome for the base map and the four scenarios. Second Column: Maps of the pixels changed between the base map of 2011 and each of the four scenarios. In the MF and FW maps, there are multiple symmetric circular desert areas. These occur because a single desert pixel in the original base map grew symmetrically outwards from all edges of desert. Third Column: Maps of the change in the value of ecosystem services between the base map of 2011 and each of the four scenarios.

Why are there Differences in Values? (Bhutan Case Study)
Resolution. The global model has a one-kilometer resolution while the national study was at a much finer resolution. Using a one-kilometer resolution implies that if any part of the pixel that touches the Bhutanese border is counted, even if only a small percentage of the one-kilometer pixel is in Bhutan itself. The total land area difference was 128 thousand hectares. Resolution also makes a difference in the biomes detected in the model. Although the national study found 3,528 hectares of inland wetlands in Bhutan, they are all smaller than 1 km2, meaning that the global study did not pick up any wetlands in Bhutan. Data Source. The data from the global model came from a remote sensing study, which used satellite images to identify the biomes based on how they looked from space. This method sometimes has a hard time distinguishing between similar biomes. For example, the global study shows 804,000 hectares of tropical forests in Bhutan, even though all of Bhutan’s forests are temperate. On the other hand, the land cover data from the national study was government data that had been extensively ground truthed. Unit Values. In both studies, the unit values for each square kilometer of biome were derived through the use of benefit transfer. In the national study, all transferred values were carefully vetted to ensure that they were from regions similar in climate, quality, and other characteristics before averaging. The global model averaged values from all over the world, making them less specific to Bhutan itself.

National Consequences Latin America ?
This is the goal of this workshop Map the changes for Latin American Countries Calculate the changes to ES Values from the scenarios Speculate on the ‘credibility’ of the land use changes relative to the scenarios 4) Speculate on how best to communicate these results to both policy makers and the public 5) Speculate on effective policies to chart a path to a sustainable and desirable future. Note: The ‘Speculations’ will be nationally specific.
