Fig. 2From: New feed sources key to ambitious climate targetsFrom top: time series of total extent of permanent pastures and meadows; arable land and permanent crops; and forest plantations. In the Alg-Feed scenario, microalgae is used to meet 40 % of demand for feed, and the land (1.8 Bha) spared is converted to plantation. Shaded ranges show the effects of population growth, the leading source of systematic error on agricultural land use projections. Historical data from FAOSTAT is used for model calibration [27]Back to article page
