Managing grazing on grasslands in a more efficient way could significantly increase global milk and meat production or free up land for other uses.…”but to achieve this target in a sustainable manner, our study suggests that we should focus on making more efficient use of currently available land resources, instead of converting land from other uses.”…

….[the study] identified areas where additional biomass could potentially be extracted from the landscape, by comparing the current level of grazing intensity to the maximum levels supported in periods of minimum biomass supply, such as winter or dry periods…”reveals a certain potential to increase grazing intensity in some places, yet shows that the actual grassland area available for other purposes remains limited”…
