234 ^ Short History of the Middle East his tenants. It is hardly necessary to point out that the blame for this disastrous state of affairs rests not with the individual landlord but with an age-old social system in which a sense of responsibility for the well-being of the land and its workers did not develop. . . . There can be no question whatever of the urgent necessity of attempting to graft on to the system this sense of responsibility, for history shows that if the problem of the absentee landlord is allowed to drift, it is liable to be solved by an agrarian revolution. . . . Throughout the Middle East the peasant-proprietor is in the grip of the money-lender. Although they own their land, they have not the means to improve it and "are no better off than the small tenants of the large landlord who hold only an annual lease/1 Owing to the resultant lack of enterprise of the fellahin and the primitiveness of thek equipment, in some countries a considerable proportion of the land which is capable of cultivation by the most modern methods is left uncultivated. It is estimated that in Egypt, Palestine, and Transjordan over 70 per cent, of the cultivable land is already utilized, while in the mountainous Lebanon the rate of utilization is so high that the only outlet for an increasing popula- tion has for some decades been emigration. On the other hand, in Syria and Iraq there are vast areas cultivated centuries ago which might once more be brought under crops by modern methods of irrigation. It is estimated that in Iraq irrigated cultivation could be extended to three and a half times its present area.2 While Egypt and Lebanon are already seriously over-populated, and the rapid natural increase in Palestine threatens over-population in another generation, Syria and Iraq have only three and four million inhabi- tants respectively, or considerably fewer than they supported in antiquity; and an extension of irrigation would undoubtedly permit a corresponding increase in their population. 'The whole area, with the exception of the Jews in Palestine, is included in the groups of population which derive at least 70 per cent, of the energy of their diet from cereals and roots. A consider- able part of the population probably belongs to the group so deriving 80 per cent, of its calories. That is to say, the area is in- cluded among the worst-nourished parts of the world. It is poss- ible to make certain broad statements which are true of populations in general which fall into this category. Malnutrition is wide- 1 Keen, op. cit., 13 f. 2 Times, 25 June 1947.
