Appropriate Technology (AT) is technology that is designed with considerations that are appropriate to the environmental, cultural, social, and most importantly the economical aspect of the intended country. AT rejects the practice of high technology in the Third World and it also rejects technological dependence in favor of autonomy.
An example of AT is the water supply devices often used in southern Africa. Hippo water rollers are used to roll barrels of water instead of water being carried on their heads. Roundabout playpumps harness the energy of children at play to pump water, but this is not exactly a low-cost option for it costs several thousands of dollars to produce.
