* By size: The Thar Desert is the 18th largest desert in the world, covering roughly 200,000 square kilometers.
* By population: It's one of the most densely populated deserts in the world, supporting a significant population due to its proximity to the Indus River and its agricultural potential in some areas.
* By biodiversity: The Thar Desert is home to diverse flora and fauna, including several endangered species. Its ecological significance makes it hard to rank in a simple hierarchy.
* By cultural significance: The Thar Desert has a rich history and cultural heritage, with unique traditions and communities thriving within its harsh landscape.
So, rather than trying to rank the Thar Desert, it's more appropriate to appreciate it for its unique features and characteristics.
