Which method will you use for distribution of rainfall in nandurbar district ?
Answers
Explanation:
The intensity of agricultural operations, the intensity of
cropping, intensity of irrigation, cropping pattern and
productivity all are related to variability of rainfall.
Variability of rainfall increases with decreasing mean annual
rainfall. Variability in excess of 20 % implies great risk to
farming (Williamson 1925) therefore, in the absence of
irrigation or dry farming practices, agriculture is reduced to
a gamble and consequent famines can be expected any time
hence,In this situation, it is essential to provide additional
water supplies for successful cropping. Rainfall variability is
measured by the co- efficient of variability of average
rainfall of 10 years.
The variation in rainfall has greater impact on agriculture
sub seqnently on economic and social life of human beings.
Hence it is highly important to study rainfall in the most
tribal district in Maharashtra i.e. Nandurbar. The necessity
of irrigation is determined by the amount of rainfall received
during the period when the crops do need it to survive. The
success of the crops depends on the rainfall during monsoon.
The climate of the district is characterised by hot summer
and general dryness throughout the year except during the
south-west monsoon season i.e. June to September. Hence in
order increase agricultural production the effective
utilization of water resources is essential. The unevenness
and uncertainness are the characteristics of rainfall in
Nandurbar. It is because of synoptic conditions, movement
of the monsoon and relict variation largely.
In Nandurbar district the average of rainfall is 801 mm. The
rainfall in the eastern part of the district is minimum and
Shahada comes under this category. The rainfall increase in
the westwards of the district .Akkalkwa and Nawapurcomes
under the major rainfall area in the district.
