A while ago, I made a comprehensive dispatch about the Challenges minigame. You can find it here: https://www.nationstates.net/page=dispatch/id=1492691

In short, if you lose any number of badges on your nation, you will lose the same number of levels in the challenge game. If you regain those stat badges, you can regain the levels.
Through challenge points, your next level-up is scheduled at 50,000.
