ALICE CARLONI Grazing management in Mongolia 271 Plate 7.4 Gers and autumn grass . Crops and industry are very minor components in the present national economy; mineral resources have yet to be tapped on any scale, the forest area is relatively small and slow-growing. Agro-industrial processing, almost entirely livestock-based, has contracted since economic liberalization. Traditionally, herders did not till the land; their economy and life-style was entirely pastoral and the climate gave little incentive to do so with the technology available to them. A little irrigated cropping, mainly wheat and barley, was done in the region of the Great Lakes and the grain parched and ground to a pre-cooked flour (similar to the tsampa of Tibet ). With the availability of suitable agricultural machinery during the second half of the twentieth century, however, it became possible to undertake largescale cereal production (Plate 7.5): in some of the less unfavourable areas of Central Mongolia over one million hectares were cultivated. The land used was, of course, among the best pasture . Some fodders (discussed in detail below) and potatoes were also grown, but the area was small compared to that of grain. The technology used, based on a rotation of alternating strips of crop and fallow , was adapted from Canadian practice. State farms and negdel (see Plate 7.6) in suitable sites produced enough grain to satisfy the population’s needs – more cereals were eaten during the collective period than previously or nowadays. FAO (1996) quotes a 40 percent reduction in the consumption of flour. In a semi -arid area with a very short thermal growing season, all agricultural operations must be carried out very rapidly, especially seed-bed preparation and sowing; yield potential is low, so production methods have, therefore, to be extensive . Considerable seasonal risk is

Grasslands of the world involved and harvest can be difficult if a dull summer delays ripening or there is early frost or snow. Cropping is not attractive to smallholders. Production was highly mechanized , and field sizes large – over a square kilometre. Harvesting was by combine harvester, often with assisted drying. Straw was recovered as feed and handled mechanically – some straw was ground up as a component of S.G. REYNOLDS J.M. SUTTIE
