1. Most of the changes are minor refactors and mock data.
2. Lesotho is added as planned with empty mock data.
3. I could not infer drought behaviour from the code.
4. I didn't load the drought scenarios bcoz I should understand drought better to know what to test.

Nice work, the comments help a lot with the review!
