摘要：In India some 123 districts have been classified as
dryland areas, all of which have an annual
rainfall ranging from less than 500 mm to 1500
mm. While dryland agriculture accounts for more
than 70% of the cultivated area of the country, it
contributes only 42% of the national food basket.
The yields in dry tracts are low, and there is always
the risk of a total crop failure as a result of erratic
rainfall. Thus dryland agriculture is faced with the
twin problems of climatic instability and low
productivity (Jain 1985). One important aspect of
dryland agriculture is the fact that production is
seasonal, which means that grains must be stored
for long periods by traders, procurement agencies
and consumers.
