EQUITABLE DISTRUBUTION OF WATER IN UPPER GODAVARI SUB BASIN: A CASE STUDY FROM

Suresh A Kulkarni1

ABSTRACT

Maharashtra state of is located in the semi-arid climatic zone where assured irrigation supply is essential for optimal crop growth. Presently, only about 20% of the state's cultivable area is brought under irrigation. Since last four decades, the state government has been giving emphasis on water resources development by constructing large and small . The state now has the highest number of dams in the country creating a storage capacity of about 40 billion cubic meters. About 70% of surface water storages are used for irrigation. In absence of integrated approach at basin/ sub-basin level, there has been lopsided development and use of water resources in the state. As the basins/ sub-basins are getting closed due to over usage of water, conflicts among upstream and downstream stakeholders and different categories of uses are escalating. Maharashtra Water Resources Regulatory Authority was established in 2005 to regulate and ensure equitable distribution and utilization of water resources in the state. Godavari basin, the second largest basin in India covers about half of Maharashtra’s geographical area. Maharashtra part of the Godavari basin is divided into 27 sub-basins. The Upper Godavari Sub-basin is one of the most developed basin in terms of agriculture, urban and industrial growth in the state. Many irrigation projects were constructed in the sub-basin to meet the growing water demand for irrigation, domestic and industrial uses. As the water demand has continually been increasing compared to the availability, the sub-basin has been experiencing water scarcity situation frequently leading to conflicts for water sharing between upstream and downstream stakeholders as also among different categories of uses. The case study presented in this paper briefly describes the role played by the water regulatory authority in addressing and resolving the dispute by framing guidelines towards sharing the available water between upstream and downstream reaches of the Upper Godavari sub-basin.

Keywords: Upper Godavari sub-basin, equitable allocation of water resources, Water Resources Regulatory Authority, irrigation and non-irrigation uses

1. INTRODUCTION

The Godavari basin is the second largest river basin of India (30.2 million ha) and partly covers six states viz., Maharashtra, , , , , and . About 49% of Maharashtra’s geographical area (15.26 million ha) comes under Godavari basin. In Maharashtra, the Godavari basin is divided into 27 sub-basins. The Upper Godavari sub-basin has a geographical area of 2.2 million ha and about 8.6 million population lives in 45 towns and 1883 villages. The sub-basin comprises the entire catchment of the from its source to Jayakwadi including the catchment areas of the rivers Mula, Pravara and all other tributaries which joins the Godavari river in this reach. There are 17 major, 14 medium, and 558 small irrigation projects in the sub-basin with design live storage capacity of 5.48 billion cubic meters (BCM). The location of Godavari basin in India and a map of the Upper Godavari sub-basin is shown in Figure 1.

The present case study deals with the equitable sharing of water between 23 major and medium dams located at the upstream of the sub-basin and the located exactly at the downstream border of the sub-basin. The upstream projects are grouped in to five complexes viz., (1) Mula, (2) Pravara, (3) Godavari-Darna, (4) Gangapur, and (5) Palkhed. The schematic diagram of these 23 major and medium dams/reservoirs with their groupings in the sub-basin is shown in Figure 2. The figures in parenthesis show their design live storages.

The Jayakwadi irrigation project was planned in 1964 and commissioned in 1975. The designed live storage capacity of the reservoir is 2.17 BCM and was planned to Jayakwa irrigate about 0.26 million ha in region. However, since 1975 the Jayakwadi reservoir was filled to its design capacity only in 8 years. The Water di Resources Department (WRD) in 2004 carried out a study to assess the sub-basin Reservoi yield based on the latest hydro-meteorological data. Table 1 shows the comparison of the virgin yield and utilization in the upstream dams as per the original planning and r the revised study.

It can be seen from the Table 1 that as per the revised study the annual 75% dependable virgin yield of the Jayakwadi reservoir was worked out as 4.45 BCM which is 20% less than the project design; while the upstream utilization has

Further, the non-irrigation use of water from upstream projects has increased from 247 million cubic meter (MCM) at the time of planning of the Jayakwadi project to 976 MCM at present (Godavari Study Group Report, 2013). This has adversely impacted the yield of Jayakwadi dam affecting significant reduction in the irrigated area as envisaged in the project design. Incidentally, the upstream and downstream sub-basin areas belongs to different administrative regions and thus the conflict seemingly became inter-regional. As the water demand for irrigation and non-irrigation purposes from both upstream and downstream of the sub-basin has continually been rising over the years, conflicts between the regions for water sharing are also escalating.

2. POLICY AND LEGAL PROVISIONS

Maharashtra state is at the forefront in the country in introducing various policy measures, acts, institutional reforms and initiatives in the water sector.The 'State Water Policy' formulated by the Government of Maharashtra (2003) envisages that the water resources of the state shall be planned, developed and managed at the river basin/ sub basin level adopting multi-sectoral approach. The policy states that the distress in water availability during deficit periods shall be shared equitably amongst different water use sectors and also amongst upstream and downstream users. In the year 2005, two important acts viz., the Maharashtra Water Resources Regulatory Authority Act and the Maharashtra Management of Irrigation System by Farmers Act were enacted by the Government. Subsequently, Maharashtra Water Resources Regulatory Authority (MWRRA) was established to regulate and facilitate, ensure judicious and equitable allocation and utilization of water resources in the state.

Due to scanty rainfall during 2012-15, there was a drought situation in most part of Maharashtra state. The live storage in the Jayakwadi reservoir in 2012 was only 3% and there was accute shortage of water for drinking, irrigation, and industry in its command area. The storages in the upstream dams were relatively higher than the jayakwadi. So the downstream stakeholders filed a 'Public Interest Litigation' in the High Court requesting to release water from upstream reservoirs to Jayakwadi. As directed by the Court, the WRD released 298 MCM water from the upstream dams of which 62% had reached the Jayakwadi reservoir. For the subsequent years (2014 and 2015) too when the Jayakwadi reservoir was filled only about 43% and 6 % respectively, the downstream stakeholders filed petition(s) to MWRRA requesting equitable distribution of water in the sub-basin invoking the relevant provisions in the MWRRA Act, 2005.

3. DECISION ON EQUITABLE DISTRIBUTION OF WATER

Based on the various petitions filed both by the upstream and downstream parties, the matter was heard and MWRRA issued an Order on 19 September 2014 asking the WRD to release 355 MCM water to Jayakwadi reservoir. In view of the intricacies involved in the matter, the Government of Maharashtra in 2013 constituted a ‘Godavari Study Group’ for formulation of guiding principles towards integrated operation of the reservoirs in Upper Godavari sub-basin (up to jayakwadi dam). The MWRRA in its order adopted the guiding principles of the reservoir operation and equitable distribution of water among the upstream and the downstream reservoirs as proposed by the Study Group Report. The Study Group has proposed operating strategies for the reservoir operation under six different storage level positions to help achieve the approximate equitable and judicious distribution of water in the upstream and the downstream reservoirs for irrigation and non-irrigation uses. This is to be achieved by following a step-by-step synchronization of storages in upstream

Strategy VI 2237 689 836 1220 457 313 (101%) (Good year) (103%) (112%) (146%) (170%) (130%)

In Table 2, utilizable water of a given reservoir is the sum of water used for drinking, industrial, irrigation, and evaporated from the reservoir during the Khaif (monsoon) season besides the balance live storage but excluding the carryover. It could thus be more than the designed live storage. The figures in the parenthesis are the percentage of the actual live storage with that of design live storage for all the reservoirs in each of the complex.

In strategy I to V, 20% less water is allocated for drinking, industrial and irrigation; while water supply for the Rabi (winter) season irrigation has been curtailed from 68% in strategy II to 20% in strategy V compared to the project design. If any reservoir on the upstream side is short of water to meet its own minimum needs (drinking and two irrigation rotations) governed by the respective strategy to be adopted for reservoir operation, no release of water from that reservoir will be allowed. Also, in case the natural storage position of the Jayakwadi reservoir in the first fortnight of October is above or equal to 65% of the live storage (Strategy-III) then water from the upstream reservoirs is not required to be released. It means, if the Jayakwadi reservoir is filled

nd 2 World Irrigation Forum (WIF2) W.1.2.06 6-8 November 2016, Chiang Mai, Thailand equal to or above 65% of its designed live storage, the situation is not considered as "water scarcity". Based on these guiding principles, MWRRA directed WRD to release 202 MCM in 2014 and 294 MCM in 2015 water from the upstream dams to Jayakwadi reservoir. The volume of water actually reached in Jayakwadi reservoir in 2014 and 2015 was 140 MCM and 188 MCM, respectively. It shows that about 30 - 35% water quantity is lost during the conveyance through the network of rivers. The additional water made available in the Jayakwadi reservoir has helped alleviating the drinking, industrial and irrigation water shortage of the downstream stakeholders.

Despite the MWRRA’s endeavour to resolve the disputes of equitable distribution of water within a sub-basin, its order has been challenged both by upstream and downstream Petitioners in the Mumbai High Court and the final Order is pending (as of 20 August 2016).

4. CONCLUSIONS AND WAY FORWARD

As the demand for water is continually increasing due to rapid population growth, rising urbanization and industrialization in the state of Maharashtra, many sub-basins are getting closed leading to conflicts between upstream and downstream users and competition among different categories of uses. Water allocations planned in most dams constructed in the past has significantly altered due to change in the sub-basin hydrology and unforeseen and increased water demand for irrigation and non- irrigation uses. Climate change is likely to exacerbate the water availabilty in the river basins further.

The case study of Upper Godavari sub-basin presented here is a classic example of the conflicts regarding sharing of water resources within a sub-basin. Water regulatory institutions like MWRRA can play a crucial role in addressing and resolving such conflicts in the best possible manner. It is hoped that the case study presented here will be useful as an example for resolving disputes related to equitable distribution of water resources under similar situation elsewhere. Nevertheless, key to sustainable management of water resources lies in how best communities, voluntary and professional organisations, policy makers and politicians come together to resolve the conflicts amicably.
