Its great as a biofuel for generating electric power. See:
develop cover crops to protect cropland soils from erosion
improve water quality in streams and aquifers using plants
stabilize streambanks and shorelines to prevent soil erosion
develop improved plants for wildlife food and cover
utilize native plants for ecosystem diversity
As for feed, I found this reference:
FODDER SUCCESS STORY - IMPROVED FODDER CROP PRODUCTION IN THE NORTHERN AREAS OF PAKISTAN
Dr. Muhammad Dost, Aga Khan Rural Support Programme (AKRSP), Gilgit, Pakistan [now with FAO in Iraq]
Lack of quality fodder, especially during winter, is a major limiting factor in improving
livestock production. During winter all stock has to rely on crop residues and fodder,
so many animals are undernourished and weak by the spring. Because of very limited land holdings
(Figure 2), lack of water and extreme weather conditions, fodder crop cultivation is practiced
on small areas. So, traditionally there is a fodder deficit from November to March, when the main
summer fodder crop season (for example maize) is over and the traditional winter fodder,
especially shaftal (Trifolium resupinatum) and lucerne (Medicago sativa), are still dormant
during the freezing temperatures.
"Multipurpose trees (willow [Salix sp.], mulberry [Morus sp.] and Russian olive [Elaeagnus sp.])
are planted on field edges and marginal land - their leaves and bark provide supplementary
fodder in winter. In some areas leaves are dried and stored for winter use."
There is an interesting photo in this page entitled:

Is there still a country (region?) called Hunza. Robert Rodale wrote a book
called "The Healthy Hunzas". Legend has it that people from the region often live
well beyond a hundred years and are in remarkable health at that age.
Other interesting photos:

and especially this one:

- talk about multipurpose living mulch!
... and more:

Amazing what you can find on the Web, real photos of farming in the legendary land of the
