Let us consider what science and technology have to contribute to the food problem.
The simplest way to increase food production, one might suppose, is to bring more land under cultivation and put more people to work on it. Some of the underdeveloped countries have resorted to this【S1】______approach, without notable success. It contains several fallacies. For one thing, it usually means moving into marginal lands where the soil and climatic conditions give a poor【S2】______. Cultivation may quickly deplete this soil, mining it for pasture or forest growth. It is often possible, of course, to turn such lands into useful farms by agricultural【S3】______; for instance, a sophisticated knowledge of how to use the available water through an irrigation system may reclaim semi-arid grasslands for crop-growing. But the cultivation of marginal lands is in any case unsuccessful unlers it is carried out by farmers Mill a centuries—old tradition of experience or by modern experts with a detailed knowledge of the local conditions and the varieties of crops that are suitable for those conditions. Such knowledge is conspicuously absent in the underdeveloped countries.
【S4】______, we know that highly developed countries have not increased the number of acres tinder cultivation, but on the contrary have【S5】______their marginal lands and steadily reduced the proportion of the population engaged in farming. Efficient farming【S6】______concentration on the most efficient lands, and it results in greater production with fewer people. The problem of the underdeveloped countries, then is to increase the【S7】______of their farms and farmers. This would allow them to industrialize and to feed their people more adequately. It is not easy to【S8】______, however. The peasant farmers are【S9】______and resistant to change in their methods of cultivation. The underdeveloped countries are greatly in need of studies and experiments to help them to【S10】______modern agricultural methods to their own conditions.
