Hello Carole, I am truly impressed with your project. Involving farming/conservation with disability is a great community project.
Moringa is a hardy plant and it is great you are able to grow it in Kitale; it would be nice if you could share how you were able to do this so you can educate others on different options of agriculture, instead of the usual maize, potatoes etc. Or if you are offering training to groups of people who can learn from your farming.
My thoughts are also on the product once it is harvested. You mentioned drying and/or powdering the leaves and using the pods for oil. PWA would greatly benefit I believe also from being involved at this end process. It would be like a cottage industry, where they plant, harvest and come up with the final product. I believe such a situation can grow a community, and they can sell their produce locally or internationally.
It would also be great to research what other products the Moringa can be made into. Who knows the oil may also be useful to make sunscreen!
Let us know how the project goes, and if I find any information on interesting uses of Moringa I will share.
