C-168765
In general, Chhattisgarh state is underlain by hard rocks with limited groundwater potentials. But decline of rainfall in most parts of the state is limiting surface water resources too. Agriculture is mostly rainfed, paddy being the main crop in the state. Groundwater is the main source of irrigation and a major source of drinking water. Cavernous limestones/dolomites form the most potential aquifers yielding up to 50 lps as in Bastar, Baloda Bazar and Bilaspur districts. Proposal for construction of energized irrigation dug/bore wells under PMKSY-HKKP-GW scheme in 109 blocks (stage of extraction within 60%) of 7 aspirational districts will enhance ground water irrigation of 7467 ha land. The stage of extraction has already escalated from 5.11% (1990) to 44.43% (2017) which will be escalated further with ongoing and future development programs. The State should undertake conservation of groundwater through regulation, protection and augmentation of the water resources by implementing rainwater harvesting and artificial recharge, along with adoption of rainfed agriculture, drip or sprinkler irrigation, pricing policy for commercial ground water extraction, exploration and planned development of yet unknown aquifers through exploratory drilling aided by remote sensing, geophysics . Based on declining groundwater level trends areas totalling 16,410 sq. km have been demarcated for rainwater harvesting and artificial recharge creating sub-surface ground water storage potential of 1030.11 MCM and an additional irrigation potential of 148430 ha. Further, groundwater pollution from geogenic and anthropogenic sources like high fluoride, arsenic, uranium, sulphate, nitrate as in Rajnandgaon, Durg, Bilaspur, Raipur and Kwardha districts is also a potential threat to the utilisable resources.This paper attempts at a holistic overview of sustainable development and management of ground water resources of the state considering the huge hydrogeological, geophysical and chemical database in the state.

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.
Groundwater Resources of Rajasthan: Status, Issues and Strategies

Rajasthan is the largest state of India covering an area of 3,42,239 sq.km and represents 10.5% of the country?s geographical area. On the other hand it has only 1.15% of total surface water and 2.6% of dynamic groundwater resources of the country?s resources due to arid climatic conditions. Surface water availability is restricted to command areas of canal system; hence groundwater is the only dependable source in major part of the state. Groundwater quality deterioration with depth coupled with low and erratic rainfall has generated constraints as regards availability and development potential of groundwater resources. Over exploitation of groundwater has caused mining of groundwater, which has set in declining trend in water level and threatening depletion of limited available fresh groundwater resources at an alarming rate. Management of groundwater resources in this context is an extremely complex proposition. The highly uneven distribution of groundwater and its utilization make it impossible to have single management strategy for Rajasthan as a whole. Any strategy for scientific management of groundwater resources should involve a combination of supply side and demand side measures depending on the regional setting and local geology and also on use of saline water. There are saline water tracts in various parts of the state. Recently conservation of water through crop diversification and use of saline water in several parts of the state has gained momentum.

Air, Solar energy, Land, and Water are the four life support systems of which, only ?Water? is amenable for its development and management to meet human needs of water. Water Resource Development structures had to be compatible to the characteristics of ?Water Resource?. With the advancement of civilization, ingenuity of man prompted him to evolve different types and sizes of infrastructure to meet changing patterns and increasing magnitude of water demand. It also stressed the need to have an integrated approach in such development. Subsequently as a soft option, improvement in management of infrastructure was the next logical step. As the issue of complexities in the competing and conflicting demands on water surfaced prominently, need for taking a holistic approach towards them was thought of and there emerged the viable solution in the form of better governance of water resources. An attempt has been made here in below to present evolution of all these developments by citing a case study of Maharashtra State in the Peninsular India. It mentions at the end a ?Vision Statement? for the future development of the State in the water sector and an outline of future planning and policies which need to be adopted. In conclusion it states a framework of desirable actions to be taken in future, to transform the ?Vision? into a reality.

Surface water resources in Rajasthan are scarce and scanty owing to hot arid climatic conditions. Major parts of western Rajasthan are devoid of any major drainage system and are reeled under spells of chronic droughts. Average annual rainfall in the state is of the tune of 540mm, decreases westward and is even less than 150mm in the western most parts of Jaisalmer district. Annual Potential evapo-transpiration is also as high as 2060mm in parts of Jaisalmer district. There are 15 river basins in the state. There are also numerous natural as well as artificial freshwater lakes including Pushkar, Rajsamand, Nakki, Ana Sagar, Kayalana, Ramgarh, Foy Sagar etc. mainly in the southern and eastern parts of the state. Salt lakes include Sambhar, Kuchaman, Pachpadra, Didwana, Phalodi, Lunkaransar etc. Indira Gandhi Nahar (IGNP), Bhakara and Gang canals have been constructed to bring Himalayan water to the desert areas of western Rajasthan in addition to other major commands of Chambal, Mahi and Narmada canals etc. In Rajasthan, irrigation projects completed include 22 Major projects, 77 Medium projects, 660 Minor projects and 3139 Tanks have been transferred to Panchyat Raj Department. Usable water is of the magnitude of 16.05 BCM and the Gross Storage Capacity created is of the order of 14.547 BCM. The Live Storage Capacity created is about 11.99 BCM. Out of the total allocated share of 17.88 BCM under interstate water agreement, average annual water availability remains 12.66 BCM due to various climatic, political, institutional or hydrological reasons. In addition to various Central Government Schemes, Watershed schemes and Mukhyamantri Jal Swavlamban Abhiyan are also implemented in the state.

Gujarat State is located in the western part of India, it is well known for entrepreneurship of its peoples. Water resources in the state are very much unevenly distributed. There are very high rainfall areas in the southern part of state, whereas the northern and western parts face desert like climate. Hydrogeologically there are diverse aquifer systems. Some form prolific aquifer system like alluvial formations of North and Central Gujarat plains. There are also hard rock formations like Granites, Deccan Basalts which form poor aquifers. Due to frequent and persistent droughts water resources management has been a challenge in northern and western parts of the state. Total annual availability of water in the state is estimated at 51 BCM/ out of which surface water contribution is 38 BCM, whereas groundwater accounts for 13.58 BCM. The groundwater plays a very important role in agriculture as well as water supply in this drought prone state. The total annual Groundwater Recharge has been assessed as 22.37bcm and Annual Extractable Ground Water Resources as 21.25bcm. The Annual Ground Water extraction has been assessed as 13.58bcm and Stage of Ground Water extraction as 64%. There are 248 assessment units (talukas) out of which 25 Talukas have been categorized as ?Over- exploited?, 5 are ?Critical?, 11 are ?Semi-Critical?,194 as ?Safe? and 13 saline talukas in the state. A well-planned strategy is required for management of water resources in the state. Number of water conservation and augmentation measures have been taken up in the state in the form of Sujalam Suflam Yojna, Sauni Yojna, Participatory irrigation management, ATAL-JAL, Hydrology Project, Interlinking of Rivers to name a few. Further steps suggested for conservation and sustainable use of ground water can be augmentation of groundwater resources through Artificial Recharge, revival of ponds, reuse and recycling of wastewater, protection of water sources from pollution, conjunctive use of surface and ground water, etc

The water sector in Maharashtra is facing critical challenges. First, uneven availability of water over space and time is the biggest challenge and secondly, dramatically increasing competing demands for water from different sectors are giving rise todisputes and conflicts. Of the total water used in the state, about 82% goes to irrigation, 12% for domestic water supplies, 4% forindustrial use, and the remaining for other uses such as livestock, hydro and thermal power generation. With the urban population of about 51 million (45%), and rapidly growing urban centres and industries, there is considerable gap in demand and supply of thestate's scarce water resources. This has posed serious challenges to water security. There can be only limited dependence upon the groundwater resources for the protective irrigation in the State as 85% area is Deccan basalt having limited ground water recharge potential. Also access to safe drinking and other domestics is a challenge in the rural areas of the State. Planning and Management of water resources in a coordinated and holistic manner is needed. Considering the scarcity of water in large part of Maharashtra and substantial utilisation by irrigation sector, there is a need to expedite measures for improving Water Use Efficiency (WUE) so that water saved in irrigation can be utilised for other non-irrigation purposes. The paper gives an overview of the water resources scenario in Maharashtra with reference to surface water and discusses various water management issues that need focused attention. The paper brings out the impact of decision of various water dispute tribunals on the water availability for the State and also the need for inter-basin and intra-basin water transfer. It emphasises the need for upscaling use of Micro Irrigation (MI), Pipe distribution system, large scale integrated MI systems throughout the State etc. for not only to save substantial amount of water but also to help in increase the productivity and quality of agriculture produce. The paper also touches upon the issues of water quality and flood management in the State.

Goa is drained by several rivers like Terekhol, Mandovi, Zuari, etc. and their tributaries, many of which show tidal influence and related saltwater intrusion. The surface water resources of the state have been assessed at about 8570 Mcum with 1465 Mcum utilizable resources (1125 Mcum surface water, 340 Mcum ground water). Presently, surface storages available are to the tune of 335.87 Mcum in the tanks, diversion structures such as bandharas, weirs, etc. The macro level surveys indicate ground water available is to the tune of 43.83 Mcum and utilization is to the tune of 33% which is considered as safe. Major and medium schemes like Salaulim, Tillari, Anjunem and minor irrigation schemes like Chapoli, Panchawadi, and Amthane irrigation projects cater to the agricultural needs of Goa State. The Sal-Amthane, Salauli-Kalay River Inter Linking Projects in Goa augmented the source to a tune of 156 lakh cubic meter. The paper discusses the water requirement and water resources management of Goa by 2051.
