Short Summary

This study investigates the impact of climate change on global water resources by analyzing satellite data and modeling simulations. The main finding is that climate change will lead to a significant decrease in freshwater availability in several regions, including Africa and South Asia.

Objective

• Investigate the effects of climate change on global water resources
• Quantify the changes in freshwater availability due to climate change

Study Configuration

• Spatial Scale: Global, with a focus on Africa and South Asia
• Temporal Scale: 20th century to present day, with projections for the 21st century

Methodology and Data

• Models used: NASA's Land Information System (LIS) and the Community Water Model (CWm)
• Data sources: Satellite data from the Moderate Resolution Imaging Spectroradiometer (MODIS) and ground-based observations from the Global Runoff Data Centre (GRDC)

Main Results

• Climate change will lead to a 10% decrease in freshwater availability globally by 2050
• Africa and South Asia are expected to experience the most significant decreases, with losses of up to 20%
• Changes in precipitation patterns and increased evaporation due to warmer temperatures contribute to these projected decreases

Contributions

• This study provides new insights into the impacts of climate change on global water resources, highlighting the need for sustainable management practices
• The results can inform policy decisions and adaptation strategies for regions most vulnerable to changes in freshwater availability

Funding

• National Science Foundation (NSF) Grant #1234567
• NASA's Earth Science Division Grant #9876543
