Let me share a few observations from Mongolia. I have seen remarkable little impact of post-communist land tenure (from public to private) on pastoralism. However, the privatisation of livestock has lead to increased livestock numbers and sales (in the good years). As export markets have become relevant, pastoralism is spatially concentrated in accessible areas and peripheral pastures are abandoned (your earlier intensification/extensification question). The Soviet dry land cultivation of cereals has been completely abandoned. The former fields are a desert now. Irrigated horticulture, by Korean immigrants, has taken off around Ulaanbaatar.
