1.1 Objective and scope These chapters are not intended as a
treatise on range management of tropical grazing lands, nor on the
agronomy of sown pastures and cultivated fodder crops, aspects of
applied science that are only one stage above scientific farming
and use of land. An attempt is made to present the vegetation
sciences, or botany and ecology in their widest aspects, as the
essential background for their application in economic land use and
plant and animal husbandry. The basic thesis is that science is
global, but that its practical application is restricted to
specific biological and socio economic habitats. The region covered
is termed the intertropical zone. This comprises the equatorial
latitudes, the tropics and subtropics. It is not only that part of
the globe lying between latitudes 30 Degrees north and south of the
Equator, as proposed by some writers (DAVIES, W., 1960; repeated by
DAVIES & SKIDMORE, 1966). Rather is it those regions of the
world in which, at the lower elevations, certain families and
members of the Gramineae and Leguminosae grow wild or can be
cultivated. It may be a matter for discussion whether these plants
in their wild communities or sown or planted crop mixtures are
better indicators of a biological environment than the instruments
and criteria of the meteorologists.
