Description
Water storage is crucial for water security in countries with monsoon driven climates. This will become increasingly important in the context of climate change. Sri Lanka has had a network of approximately 23,000 small tanks which date back to the third millennium BC, which create a buffer to mitigate the impact of floods in the monsoon season and of droughts in the non-monsoon period. However, 21 percent of these are currently non-functional or damaged. This study uses a combination of tank survey data and global satellite datasets to design and implement a prioritisation for tank rejuvenation.
