What is the most effective way to increase the living standard of people in developing countries, in relation to engineering?
I'm a university student wanting to have an engineering career in developing countries. I'm not sure what part of engineering I want to specialise in, and would be grateful for any ideas, especially from people who are in this field themselves. If not, that's kl too.
Also the main problems that need to be solved to raise the living standard (social, physical, emotional, etc.)
