Agroforestry can increase water availability to land-use systems

Hello. Work assignment is to write an essay and explore the hypothesis: “Agroforestry can increase water availability to land-use systems.” I came up with a little plan for the dissertation (you will find it in the files as “threesandwater” and also the book by Young,which may help you ). I’ve made the content according to the main information they were giving at school, focusing mainly on water and not so much on erosion, even though both are closely related. But already over an hour I’m sitting here helpless and don’t know what to do next. I have to go to work so pushing me time. :/ You can add any other information or ideas that come to your mind, or change the order if it doesn’t suit you. I’ll leave it up to you. Thank you very much.
