ABSTRACT
The Middle Ganges Valley lies between the dry Upper Ganges Valley and the very wet region of the Deltas. This chapter examines the problem of the density of population in the Middle Ganges Valley specifically from the point of view of agricultural productivity. In the Middle Ganges Valley the climate is so moist that the wheat crop is liable to suffer from rust. The importance of a crop depends not only upon its own range of environment, but also upon the range of environment of other valuable crops which may be grown in preference to it. The chapter analyzes the varying importance of the different wet and dry crops in relation to the agricultural productivity of North Bihar and South Bihar respectively. In South Bihar the density of population is higher in the northern alluvial tracts bordering on the Ganges than in the arid tracts to the south.
