Draught Animal Transport
Freight in most regions of the developing countries is often
small in weight, if not in volume, and the produce in the
rural areas rarely exceed 750 kg (an average discerned from a
survey of Indian cart operations). Animal drawn vehicles are
economical for loads ranging from half to two tonnes over
distances up to 40 km in the course of a single day. Trucks
require at least five tonne loads over distances of 100 km or
more for 250 to 300 days of the year, if operations are to
break even. In contrast, animals work only for 50 to 100 days
in conjunction with carts. In the carrying of sugar-cane,
cotton, tobacco, wood for fuel, hay, bran for dry feed,
fertiliser, and manure in the rural areas, animal drawn
vehicles enjoy a distinct advantage over trucks. They are
thus extensively used for intra-village and inter-village
transport. The animals are used for ploughing, tillage,
carting and a variety of farm operations so that the farmer
is able to spread the cost of maintenance over a number of
operations. Cart designs are highly commodity-specific. Large-
volume and low-density loads call for a different kind of
platform structure than concentrated commodities like
firewood, coal, brick, etc. In order to improve on the
efficiency of animal drawn vehicles for rural transportation,
following measures should be taken:
- improvement of vehicle design (pneumatic tyres, bearings,
axles, etc.),
- improvement of harnessing of animals (in present designs
the animal not only hauls the combined weight of cart and
freight, but also carries an appreciable weight of its
own body),
- improvement of animal breeding (this measure eventually
will lead to increased and more efficient motive power).
The proper audit of existing energy sources and the pattern
of energy end use by different activity sectors of regional
economy is essential for framing the future plan for energy
strategy for alternative resources.
