Forces of production include the objects, instruments, and products of labour which man interposes between himself and the object of his labour. The social relations of production are the class relations of the society that is work relations, distribution relations, exchange relations and property relations. The ability of man to act and change nature is not limited by history and society but equally by the structure of matter itself. Which of the possibilities immanent in matter are realized, and to what degree, always remains a function of the level of the material and intellectual forces of production. In a society where men are still not in control of their full productive capacity vis-a- vis nature the basis of human existence, that is material production remains qualitatively and quantitatively low. Thus, man's helplessness against the vagaries of nature signifies that man in his appropriation of the material of nature is still bound by the limitation of nature. Man's capacity to articulate with nature is raised by improvement of machinery, appliance of science to production and specialization in production as is possible in a particular mode of production, are characterized by limited improvement of machinery, limited appliance of science to production and limited specialization in production. As a result production is largely small scale and labour and land productivity remain very low. For precapitalist societies, backward forces of production limit the ability to produce and this leads to the occurrence of famines and food shortagesenCrops and climateAgricultureTanzaniaThesis
