There are many residential kitchen type cabinet latches available at home improvement stores like Home Depot, Lowes, etc. Some are magnetic, some snap, some use velcro, some are used with small children in the house. You can even install key type locks if you choose. (like what goes on a desk drawer) Most hinges are available with some type of spring loaded self closing feature. Pick your poison. Certain roads in New Mexico are so bad that I have to use strap ties and bungee cords to prevent things from flying about because the doors/drawers fly open. Non skid shelf liner also helps.
