Multi-level governance is like when you are playing with your toys and you have a big toy and little toys. The big toy is the government that everyone knows about and the little toys are smaller governments that help the big toy with different things. When these little toys work together, they are like a team helping the big toy with making rules and making sure things are fair for everyone.
In real life, this means that there are different levels of government like the federal government that makes big decisions for the whole country, and then there are smaller governments like state or city governments that help with making rules for their specific area. These different levels of government work together to make sure that everyone is being taken care of and that rules are being followed.
For example, if there was a big problem like a natural disaster, the federal government might send resources and money to the state government to help them handle the situation. The state government would then work with the local government to decide how to use those resources in their specific area.
Overall, multi-level governance is like a big team of governments working together to make sure everyone is happy and safe.
