I have heard of this kind of agroforestry in the African context of the mountain Chaga clan communities living on the slopes of Mt. Kilimanjaro. Very large, almost urban, communities were said to live on the slopes but their size unapparent because of the cultivated forests they lived in the midst of. Similar approaches, but built on a base of polyspecies aquaculture, was planned for the The Millennial Project —in part, I suppose, because Mt. Kilimanjaro figured largely in that space development scheme and the originally planned marine arcologies seemed to mimic it in shape. Potential for carbon sequester in the the Amazonian area has also been attributed to ‘terra preta’ cultivation ( https://en.wikipedia.org/wiki/Terra_preta <https://en.wikipedia.org/wiki/Terra_preta> ), which was another industry I proposed for TMP building on its possible mariculture waste. So-called ‘food forest’ gardening or ‘wild gardening’ has become something of a fad recently in the US, serving to promote and circulate ideas of permaculture. However, while they save effort in maintenance overhead and can be attractive, they don’t actually produce as much as high-density urban farming techniques do, at least in the temperate zones. Still, certainly a hell of a lot better than a yard full of grass… Eric Hunting [email protected]
