India is a water stressed country. Regionwise scenario is different but in general surface water resources are not sufficient to fulfil the need of the country. Available sites for water storage are limited and are located in reach regions which makes it difficult to rationally distribute the available surplus water resources to the deprived regions. This compels the extraction of groundwater in the deprived regions. Even in the command areas of the dams the tail enders do not get water and hence they have to depend on groundwater. Cropping pattern has been continuously changing due to market variations and hence the regions which are not expected to grow water-intensive crops have started growing them by meeting the water demand from precious groundwater. Objective of agriculture has been changed from food production to profit-making. Urbanization and Industrialization have furthered the dependence on groundwater. The erratic rainfall sometime is the cause of depending on groundwater. In all, the reasons for dependence on groundwater are many and the overall dependence on groundwater has been at present between 50 % to 90 % in different parts of India. For last so many years that the dependence on groundwater has been on increase which has posed a serious threat of quantity and quality of water almost in the entire country and the present model of economy, agriculture and development as a whole has become a subject of reconsideration on the ground of sustainability and environmental change. The root cause of this situation is the unsustainable ways of resource management we have adopted. Gujarat is one of the most suffering states in water scarcity because of all the aforesaid factors. The objective of the paper is to discuss the issues and the probable solutions such that that the future course could be corrective and is approached early to save the future of the state and the entire country.

The increasing pace of ground water extraction in agricultural, industrial and domestic sectors during the past four decades has led to problems of continuously declining ground water levels and deterioration of groundwater quality in many areas of Madhya Pradesh. This has threatened the sustainability of many dug wells and tube wells. Depending heavily on agriculture-based economy, the State requires assured irrigation for sustainable agricultural productivity. Groundwater is the major source of irrigation, and also the sole source of drinking water. But the development of ground water is constrained due to heterogeneity of the formations, non-uniformity in degree and nature of the weathered and fractured zones of the aquifers. It is observed that there is heavy surface run-off in many areas during the monsoon period often resulting in floods, yet these very same areas face crisis of water during the summer. This flood? drought syndrome is basically resultant of improper management of available water resources. As ground water is an annually replenishable but limited resource, augmentation of the recharge to ground water is the only option left for ensuring its sustainability.The present study is aimed at identifying the areas in Madhya Pradesh suitable for artificial recharge to arrest the depletion of ground water resources on the one hand and create additional resources to cater to the domestic, agricultural and industrial needs in the State.

Drylands of arid Rajasthan are well known for Drought and hot Desert having diversified hydro-geological conditions. Potential aquifer systems include unconsolidated (Quaternaries deposits), semi-consolidated (Tertiary Sandstone, Lathi Sandstone etc.) and fissured consolidated formations. Groundwater level is generally deep especially in western Rajasthan, where it reaches even 150m below land surface. Quality of groundwater is poor in many parts due to geogenic and anthropogenic reasons. Stage of groundwater development in the State is 139.88% with 185 blocks categorized as over-exploited. Groundwater related issues include deep and declining water levels, low groundwater recharge, over-exploitation, drying up of potential aquifer systems, high salinity, fluoride and nitrate concentration, industrial pollution, water logging and lack of appropriate water management. Management options include supply side and demand side measures i.e. water conservation, regulation, protection and especially structural measures for augmentation of resources by large scale artificial recharge of aquifers, for which financial provisions by the Government/incentives to individuals need to be introduced. Scope for artificial recharge of aquifers exists on account of availability of thick permeable geo-formations, deep & declining water levels, and availability of surplus monsoon water in northwest India, which otherwise goes waste flowing to the neighbouring country. Regulatory measures including notification of 35 block areas, mandatory provision for issuance of NOC for industries/ infrastructure/mining projects for controlled groundwater withdrawal. etc. are being taken up by Govt. organizations. State Water Policy is in place and rooftop rainwater harvesting is to be made mandatory for all buildings. State Ground Water Legislation and State Ground Water Authority need to be constituted and regulatory measures be enforced by Rajasthan Government in line with CGWA. There is need for integrated participatory approach of water management. Rajasthan being the most water deficit State in India, deserve to be given ?Special Status for Water Resources? for financial and other purposes by Government of India.

Gujarat Alluvial plains are well known for prolific aquifer system but due to overexploitation of groundwater in North Gujarat districts, the ground water levels have shown a declining trend, which entails higher water lifting cost in addition to the increasing investment in deepening of wells. As natural recharge of groundwater is not commensurate with groundwater extraction, the groundwater levels have dipped more than 190 m below ground level at some places of North Gujarat. In such areas, it is felt that artificial recharge of groundwater has much scope in water conservation and augmentation. Central Ground Water Board (CGWB) has given a new dimension to the groundwater sustainability in North Gujarat through harvesting of the surplus runoff and storing the same in the sub-surface reservoir adopting artificial recharge techniques.The present paper deals with the various activities undertaken by the Central and State Governments to arrest the groundwater level from further decline and also maintain the quality of groundwater. Based on the Pilot studies in the UNDP assisted project during the years 1980-85 in the Gujarat State, CGWB has advocated for artificial recharge of groundwater by spreading channel and injection methods to counteract the impact of overexploitation in the North Gujarat. In the Central Sector Scheme (CSS) of Ministry of Water Resources (now Ministry of Jal Shakti, Department of Water Resources, River Development & Ganga Rejuvenation), Government of India, demonstrative artificial recharge structures have been constructed by the State Government in the Saraswati river bed at Madhu Pavdi check Dam in Sidhpur, Patan district, Due to non availability of surplus water in the North Gujarat Region, Government of Gujarat launched an ambitious inter basin water transfer program known as Sujalam Sufalam Yojana. In this Sujlam Suphalam Yojana one major unlined recharge canal named as Sujlam Suphalam spreding canal has been constructed with a length of 332 km from Mahi to Banas River which diverts of surplus flood waters of Kadana Reservoir and the Narmada to the water deficit areas. In the Lift Irrigation scheme, nine reservoirs of North Gujarat region are planned to be filled by laying pipelines utilising surplus flood water of Narmada.

In western India, the states Goa, Gujarat, Maharashtra and Rajasthan having area of 0.11%, 5.97%, 9.36% and 10.41% of India respectively have 0.24%, 6.83%, 13.48% and 4.52% of the total population of the country. The area, except Goa which records high precipitation, receives moderate rainfall. Arid conditions prevail in north Gujarat and major part of Rajasthan. The utilization pattern of ground water is uneven across the region resulting in ground water stressed conditions and over exploitation in some parts, particularly the arid regions and sub-optimal ground water utilization in others. Water level varies widely being very shallow in the southern part and deep to alarmingly deep in the northern part, having deepest water level of the country in Bikaner district of Rajasthan. Water quality is of concern in the major parts. In considerable areas, some chemical constituents exceed the permissible limit for drinking water, and large patches with brackish to saline water are encountered in Rajasthan and Gujarat. Sporadic occurrences of Fluoride and Nitrate in ground water exceeding the permissible limit for drinking water are spread almost throughout the region which necessitates cautious use of ground water in these areas for drinking purposes. The stage of ground water development is 37%, 68% and 54% in Goa, Gujarat and Maharashtra respectively. In Rajasthan, the stage of ground water development is 140% and 164 out of 248 ground water assessment units are overexploited and 23 ground water assessment units in Gujarat are over exploited. This requires immediate judicious intervention without which some areas will not be able to meet even the drinking water needs. Groundwater withdrawal requires to be strictly regulated so that it does not exceed the annual recharge and also that it does not disturb the hydro-chemical balance. Alarming declines in groundwater levels warrant immediate attention for taking-up of recharge schemes to arrest further decline and augment the groundwater resources. In areas of scanty recharge, ground water should be allowed only for drinking water purposes. In other areas, along with water conservation and ground water augmentation measures, demand side management using micro irrigation techniques and change of cropping pattern etc should be religiously adopted.
