Better layout for showing 3 tables on a page

There is a dashboard page which is managed by admin for monitoring countries, industries and notifications going to end user.

I want to show these 3 tables on single page. I have designed those using wire-framing software but I feel this is not efficient design and can be more better. Can anyone help me out for better and efficient design?

Also there is setting icon against each country and industry which I want to move into the table header. But as you can see there is no space to move that setting icon into table header.
