Also, "sustainable agriculture" is a very general term. It is nearly
meaningless these days, given that (as someone noted) many people who
claim to be researching sustainable agriculture do not think in terms of
whole agroecosystems, and therefore are unlikely to create anything very
sustainable. I would argue that polyculture, integration of
human/animal/agricultural/natural systems, and practices advocated by
permaculturists, are essential to a truly sustainable food/life system.
"Agroecology" originally meant something very
similar to "permaculture", when Miguel Altieri first coined the term, but
it too has been coopted by the mainstream. Again it can mean the
consideration of whole ecosystems, but I know several other students in
my "agroecology" PhD program who are studying extremely reductionist
questions in conventional high-input monocrop systems. Many of them
study rates of decomposition in rice straw.
(which I suppose is useful to confirm the durability of rice straw as a
building material)
