* the share of grass in the feed rations of cattle and sheep and goats, which will become smaller as some of the grass will be substituted by feed crops.

* grazing, which will become more intensive. This would require better management of grasslands, including for example the use of grass-clover mixtures and fertilisers, bringing the length of the grazing season in tune with the period of grass production, and rotations.

In the so-called Global Technology ([[HasAcronym::GT]]) scenario of the Rio+20 study, all such interventions have been combined, resulting in more production in mixed systems (+10%), larger carcass weights (+10%), higher off-take rates (+10%), more efficient feed conversion of sheep and goats (+10%), more feed crops (15%) and higher grazing intensities (15%). When included in the baseline scenario, this package leads to a considerable reduction in grassland area – by about 15% compared to the baseline scenario for 2050 (see the figure in the baseline scenario section). This then also leads to an increase in the area where biodiversity may develop.
