In the so-called Global Technology ( | In the so-called Global Technology (GT) scenario of the [[Roads from Rio+20 (2012) |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. | ||
