Urban permaculture in the suburbs of Uganda

Hello permies , I need advice on this! Iam a 22 yrs old girl who would like to start up a project of urban gardens in the suburbs of Kampala. My intention is to help these people cut down there costs on food as it's very expensive. And to help the youths around acquire gardening skills because most of these don't go to school. And the environment around these areas isn't really pleasing as most of the places are flooded most of the times and living conditions and the health isn't good all together. So I would like to be advised on what to start with, maybe any fund raising options for the tools to use . I will be so glad if we work together come up with a Great solution to help and teach these people. Thank you so much and I will be glad to hear from you!
