Groundwater being one of the most valuable resources
of earth needs to be utilized properly for the healthy and
economic growth of any region. The present study was carried
out in Eastern part of India, where it is blessed with plenty of
water resources but its utilization is very poor as compared to
another part of India, which has been reflected through net
cropped area, cropping intensity etc. Orissa, being one of the
resource-rich States in India still struggles with low crop
production and cropping intensity status. The groundwater
development of the state is only 18.31 % out of total replenish
able groundwater resources of 2100928 hectare meter (ha-m).
Groundwater recharge being one of the most important
components in the hydrologic cycle, it has to be estimated for
any particular area before planning for any interventions. The
natural groundwater recharge was only 22.31 % to 24.87% of the
annual rainfall received in 30 districts of Orissa. The highest
amount of recharge of 39.75cm was from Balasore and the
lowest recharge of 26.47cm was in Rayagarh district of Orissa.
However the estimation method was very crude as it is based on
only rainfall of the particular area. More detail study on recharge
aspects can be done under basin studies in the different region.
Assessment of groundwater resources and planning for efficient
use of groundwater in the agriculture sector has been planned
based on crop water demand of each district of Orissa. The
groundwater earmarked for irrigation is 1678038 ha-m.
Considering crop water demand of 1030.5 mm (as per FAO 56
Penman-Monteith) during dry month period (November to May)
the expected area to be irrigated is 1628372 ha. Since rice is
dominated crop of this region even during rabi and summer
season, another high-value cash crop through groundwater use is
economically viable. For exploiting groundwater during rabi
season, it is essential to know under-utilized and over utilized
blocks of Orissa as the coefficient of variation was as high 133 %
in Jagatsingpur district to as low as 1.43 % in Deogarh district.
The groundwater development was a maximum of 77.61 % in
Baliapal block in Balasore district. This block is dominated with
summer paddy (January to April/May), which needs more
frequent irrigation water for harvesting optimum yield.
