Three different water management practices are described here, namely the 'phad' system of Maharashtra, a cooperative society in Gujarat and Sinchai panchayats in MP. Statistical information about the number of tanks in Mysore state from 1799-1902 and the irrigation area under channels and tanks from 1880 to 1951 are also presented. The appendices present valuable case studies about the following tanks:
Southern India as well as the arid areas of Central and Western India have seasonal rivers which limit the scope for canal irrigation while the scope for wells is limited due to the presence of hard granite and gneisses. As a result of these, tank irrigation is prominent in these areas.
This study is primarily concerned with small reservoirs. Karnataka, Andhra Pradesh and Tamil Nadu have thousands of old tanks in various stages of maintenance. However, the decay of the management and reward mechanisms in place earlier have led to a corresponding decay in these tanks. While the old social systems that maintained these tanks are no longer in existence, they have not been replaced by satisfactory institutional arrangements. This book aims to learn from the history of tanks and examine their relevance to the present.
From here, the authors move on to choosing areas for the construction of tanks for which they begin with a description of the agro-climatic zones of Karnataka. The characteristics of the following zones are explained:
The pros and cons of constructing tanks in each of these zones are described. The southern part of the dry belt is reported as having the most favourable conditions as well as a pressing need for tanks. Accordingly, a large number are to be found here.
The book then also looks at tank construction during the following reigns:
The Chalukyas of Kalyana are discussed in some detail, as their reign is considered the golden age of tanks. The dynasty, as well as the tanks and canals constructed by them are discussed. It was in this period that the technique of planning a cascading series of tanks for flood control as well as irrigation was refined. Several cases of water supply such as the tanks at Bagali and the Kalyana city water supply are described. The contemporaries of the Chalukyas, the Cholas, are also mentioned. The Hoysalas are described as the greatest builders of tanks in Karnataka in the ancient period.The history of these tanks, the capital region, its neighbourhood, the management system, and the people are all mentioned.
This chapter covers the period between 1336-1799 AD. It begins with the Vijayanagar empire, where some of the biggest projects in the history of south India were initiated. One of the biggest tanks built then, the Sulekere tank is still in existence. Known now as Shantisagara, it is covered in detail in Appendix 2. A chronological narrative of the tanks built in the medieval period is presented in this chapter.
It is following the commencement of the British rule, that a written record began to be maintained of the existing number of tanks, the area irrigated by them, and expenses incurred on them. This chapter studies the situation of tanks in south India from 1800-1956. Mysore State, Bombay Presidency, Bellary, Hyderabad, Coorg, South Canara are all covered. The chapter then looks at the situation since 1956, when the princely states were merged to form the political states. The decline in tank irrigation between the First Plan period (1951-56) and the Sixth (1980-85) is examined.
Construction practices and guidelines for tanks as detailed over the periods are described in this chapter. An inscription belonging to the Vijayanagara period describes the twelve requirements and the six faults in tank construction. A sense of the pragmatic nature of this inscription is obtained from the first requirement, which is that of a happy and rich king desirous of acquiring permanent fame !
The authors then elaborate upon the following aspects of tank building:
The present status of construction is discussed. One section deals with anicuts, which are barriers that enable diversion of flood waters to adjoining lands. The regulations laid in the Arthasastra and other texts for maintenance of structures are described. The traditional institutional and financial arrangements for ensuring good maintenance are described in chronological order from 986 AD to 1987. The authors deplore the decline in maintenance of these tanks, and stress the need for people to assume ownership and responsibility of these tanks.
Again calling on the Arthasastra and the Kunala Jataka among other documents, the authors talk of the proper regulation of water. Construction costs, public and private investment through the ages are discussed, as well as the reasons for the decline of private investment in developmental works. This section also looks at water charges through the periods beginning from the Mauryan empire to the present period. The chapter ends with the recommendation that farmers be entrusted with the maintenance of the tanks that they derive benefits from.
The authors describe the need for revival of our tank system. They stress that a comprehensive watershed development plan needs to include tanks. Traditional practices such as that of granting a small portion of land to an entrepreneur in exchange for tank construction need to be revived. A synthesis of traditional finance and management systems with modern government infrastructure and institutions may be the best means for ensuring the continuance of this unique method of irrigation and water supply.
