How about a natural Fukuoka type plan for a plot of land wherein the
existing seedbank is allowed to grow and compete for succession
- a public learning garden! interspersed throughout the roadside
landscapes, integrated with the water impoundments, catch crops (swales
catch runoff to irrigate lowland gardens adjoining (on downhill sides of
the swales) allowed to develop unattended, providing wildlife habitat
and food - I am thinking of benefits from a mix of eleagnus, cedar
and/or juniper, carpets of native ground cover: mint, Creeping charlie
or ground ivy - the large leafed, prolific, medicinal, fragrant,
invasive catch crop ideal for compost piles and Hugelkultur
(Glechoma hederacea http://en.wikipedia.org/wiki/Glechoma_hederacea),
chickweed, tall sweet clover, Alsike clover and miscellaneous other
volunteer wild plants.

I think it is about laws of thermodynamics. Go for the most concentrated
accumulation of energy, whether it is light, heat, nitrogen as in
manure, water from within a watershed....and recycle it through
successive systems of usage and successive cycles of reuse and
recycling, eliminating errors in the wastestream.
