In this research, we concentrated on analyzing desertification which is regarded as one of the historical global environmental issues, collectively known as drylands. Drylands area is occupying 42% of the earth’s surface land with responsible to hold 38% of the global population, which has a significant meaning to our planet. Along with the acceleration of climate change and expansion from anthropogenic activities, the desertification’s impacts are projected to be profound. In the aims of sustainably developing the formation of society, we applied the LCIA concept to analyze desertification with related impacts so that we can provide a more inclusive quantitative vision for stakeholders. However, the quantitative assessment and framework for desertification are still lacking agreement on which between LCIA and ecology. Thus, firstly we proposed the framework for desertification as an extended LCIA midpoint to the land use. Then we analyzed and predicted the desertification under different scenarios and try to bridge the characterization factor between inventory to the midpoint. Finally, we incorporated the model from an ecological way to evaluate the biodiversity loss as an endpoint to desertification and complete the challenging view of the connection between desertification and biodiversity. The primary results show the drylands area in 2015 is 53.1 million km2. At meanwhile, we compared our results of desertification area with former studies, a report from the united nation for global drylands reported the dryland zone in 2011 was 50.80 million km2. As for characterization factors between inventory to the midpoint, the intensity shows a higher potential vulnerability around central Asia to the black sea, northeast Australia and central America, the CF range from -7.62E-07 Ha/tCO2 to 4.63E-06 Ha/tCO2 among 5 GCMs. Most of those locations were under a highly warming level and high-water consumption, a more detailed interpretation would be also carried out later on.
