While both approaches adopt land and water availability as the main criteria to select countries with expansion potential, AAAID proposes an increase in cultivated land by 4.2 million ha, of which 2.0 million ha and 1.25 million ha are proposed in Sudan and Egypt, respectively. As discussed in chapter III, Egypt already allocates around 50 per cent of its arable land for wheat, and with less than the world average per-capita share of arable land, and water withdrawal exceeding the sustainable renewable level, Egypt is considered both a land- and water-scarce country. Prospects for higher productivity are also not realistic given that Egypt falls within the high yield countries exceeding the world average by more than twofold.
