Wayne raises some interesting points, most of which I agree with, but he says a few things that seem to need challenging. First, my American Heritage Dictionary says "landscape" derives from the Dutch word for schap = ship. The online Free Dictionary goes back even further and says it derives from the Indo-European route scap = state, condition. See http://www.thefreedictionary.com/landscape
Second, I'm not too sure what Wayne means by the comment "Anything done to any 'landscape,' particularly agricultural (Fr. agri, "field" and cultus "cut") ones, should increase biological diversity." Again, my dictionaries show a somewhat different word derivation -- "agriculture" derives from Latin ager = land and cultura = cultivation. But the more important point is that it's well accepted that modern landscape management can and does result in decreased biological diversity in many systems. Consider that in my part of the world diverse shrub-grassland systems have been replaced by large and extensive wheatfields or crested-wheatgrass range monocultures. Multi-age diverse species forests have been replaced by extensive single-age single-species tree farms. And the corn-soybean monocultures of our midwest seem to be less biologically diverse than the former grass-woodland prairies. Granted, traditional farming has sometimes resulted in increased biological diversity. Again, in my part of the world smaller brush bordered diversified farm fields once replaced less diverse oak-grass savannas, but these have now been replaced with less diverse and larger grass seed fields. And I've read that traditional coffee farms may have replaced less diverse tropical forests, but these are now being replaced by even less diverse coffee plantations.

It seems that I corresponded at length with someone working there a few years ago, but I can't remember her name. I will not be submitting a proposal. WT PS: The term "landscape" is derived from the Old Dutch word "skep," meaning "to cut," to "hack," etc. Its meaning has been altered by semantic erosion over the years, but it may be useful to consider its origins and the level of consciousness with respect to its consequences, particularly in this context. Certainly a food-production system that requires less labor, materials, and equipment, such as a biologically diverse ecosystem, whether by accident or design, might be considered more, not less efficient and bottom-line productive, than an exploitative, expedient, wasteful "system" that comes from an unwarranted assumption that "increases" are unlimited, whether through "Green Revolutions" or "Genetic Engineering." Such systems are, however, profitable in terms of money extraction, particularly for export-based economies, aka "cultural parasitism."
