Abstract
The HRSEZ is proposing to occupy an area of 25000 acres of land partly in Gurgaon district and mostly in Jhajjar district. The Groundwater moves from all the directions towards the area. Hence water logging is very common feature in this region. According to agricultural qualities, the study area can be divided into several small areas namely Brick kiln, Ravines, High Salinity, Ravine Based agricultural land, Water logged and Deep Water Table Lands. The major portion of the study area is barren and not suitable for agriculture. Agriculture is associated with only Water Logged areas. Thus only 15% of the land is suitable for agriculture. Sub surface water logging could be identified as the major constraint to crop production. The water logging reduced the ear number and hence is the major contributor towards the yield difference. The ear numbers accounted for 66.6% of yield differences in cereals.
The Introduction of the canal system in Jhajjar District is mainly responsible for the existing water logging condition and soil salinization in 16% of the area. This is due to rising water table of saline water in major parts. Though this problem has assumed a serious proportion yet it is still possible to tackle it with careful planning. The Water Level Fluctuation in the area free from water logging is about 5m and in the water logged area the Water Level Fluctuation is very small amounting to 10-15cm. After establishment of HR-SEZ, there would be a requirement of 400-500 MLD of water. This would create a ground water trough in the region. Water logging can be removed due to this. The water level fluctuation in these areas would increase. For every 1m increase in Water Level Fluctuation, there would be about 33% increase in crop yield. Therefore for 5m increase in Water Level Fluctuation, there would be further increase in crop production. Apart from this after development of HR-SEZ, the amount of recycled water would be 480 MLD, which can irrigate much greater area than is possible presently. The quality of this water would be high in nitrogen and phosphorous which would increase the fertility of the soil which ultimately increase the crop production and types. In this way the creation of HR SEZ will not only beneficial to the Industrialist but also good to the farmers in the surrounding areas..
