The arid zone of India is the most fragile
ecosystem facing extreme droughts, erratic
and high-intensity rainfall, seasonal variations
in climatic pattern, abundance of
solar energy and high evapotranspiration.
The arid region is spread over 38.7 m ha,
while the semi-arid region accounts for
34% of the total land area. In recent decades,
the semi-arid region has expanded
by 10%. The newly formed semi-arid
region in North India alone accounts for
4% of reduction in rainfall and increased
evapotranspiration have led to increased
aridity1. Under such adverse situations,
traditional agroforestry plays an important
role in providing food, fodder, fruits,
fuel, etc. and also provides security to
the local people and animals/livestock
during extreme drought conditions. The
traditional agroforestry system is a permanent
feature of a landscape, where
farmers without disturbing the natural
tree component, integrate crops, grasses
and animals. Especially, under arid regions,
a clear-cut demarcation in distribution
of agroforestry systems based on
rainfall gradient can be seen, for example,
khejri (Prosopis cineraria)-based
agroforestry system performs well under
400 mm rainfall zone; Ziyphus sp. – P.
cineraria-based agroforestry system
between 200 and 300 mm rainfall and
shrub-based system under less than
150 mm rainfall2. Some species are particular
and unique to specific zones/areas
due to rainfall, soil or other microclimatic
factors. Such types of species are not
found in other regions and the growth performance
of the species is also not assured.
One such endemic agroforestry species is
Vachellia nilotica subsp. cupressiformis
(J. L. Stewart) Ali and Faruqi (Acacia
nilotica subsp. cupressiformis), a subspecies
of A. nilotica.
