Ten thousand years ago almost everyone in the world was hunting and gathering but by áòòò years ago these were in a minority.

There are three sources from which seed enters the bank (Fig. â), namely (i) 37 38 Generation Fig. 1 A conceptual model of the sequential phases for pasture and forage crop establishment and of key biological, environmental and management variables influencing establishment outcomes.
There were relatively few humans in the world as agriculture began, but as Larry Busch ("ññâ) observed `ever since the ¢rst hominids stalked a mastodon, ate a wild berry, or cleared brush from in front of a cave, we have been making nature together'. Of course at ¢rst it was hardly noticeable, but technologies we have developed have enhanced our abilities to make and remake `nature' as well, of course, as amplifying the rate at which, for better or worse, we do this (Mooney, "ññã). The technologies started with writing and ploughing and continue today with satellite images of The title of this chapter follows the perspective we presented in Chapter ": that grassland systems are socially constructed.
