Mounting Antagonism towards Big Dams

The assumptions underlying irrigation planning are being increasingly questioned, The role of major irrigation works based on big dams in particular is under serious scrutiny by environmentalists, soil conservationists and social and natural scientists. Unfortunately irrigation planners have baulked at engaging in an open dialogue and discussion with their critics.

Impact of Irrigation on Farm Economy in High Rainfall Areas-The Kal Project

During the pre-independence period an impression prevailed that returns to irrigation in high rainfall regions of the Indian sub-continent would be very incommensurate with the comparatively high investment outlays needed for developing irrigation resource, both under public and private aegis. In view the paucity of ex post evaluation studies, this impression still persists.

Irrigation in Kerala

B D Dhawan IN their attempt to understand why agriculture in Kerala is stagnating lately, K P Kannan and K Pushpangadan (Review of Agriculture, September 24) have made some adverse, observations with regard to irrigation. These deserve attention for more than one reason For one, their paper appears to be part of an ongoing research endeavour. Hence, the discussion might prove helpful in improving their analysis and interpretations of the irrigation-related results.

Development and Management of Water Resources in North-Western India

Dryland versus Irrigated Farming

government has landed into a constitutional crisis because of the chief minister's inaction over the charges of rigging levelled against his government by some of his cabinet collegues belonging to the Forward Bloc and the RSP on the election day. The chief minister too has admitted that the minister's reported remarks have created a political crisis in the Left Front. However, the panchayat poll which had generated some degree of acrimony among the Left Front partners ended on March 4 when the election results in all the booths were announced and the CPI(M) was found getting absolute majority in all the panchayat. bodies. An interesting fall-out of the election is that the Forward Bloc and RSP, the two major Left Front partners, who were embroiled in bitter squabbles with the CPI(M) during the panchayat poll campaign, have cooled down considerably after the announcement of all the results. Two Forward Bloc ministers, Kamal Guha and Bhakti Bhusan Mandal and the RSP minister, Debabrata Banerjee, who had openly criticised the CPI(M) in the election meetings for its "big brotherly attitude" have become quiet these days. Perhaps they are maintaining complete silence after witnessing the performance of the CPI(M) against whom the Congress as well as their own parties had launched a severe attack.

Towards a New Water Policy

a thorough enquiry into the matter and put things right. It is not enough to listen to the givers. It is more urgent to listen There is little that is new in the National Water Policy adopted by the National Water Resources Council last month, except perhaps the idea of transferring water from one river basin to another. The technological and political limitations to such transfer need to be better appreciated.

How Stable Is Indian Irrigated Agriculture

B D Dhawan Instability of irrigated farming during the period 1970-71 to 1983-84 is here assessed and compared with the corresponding instability in rainfed farming. That irrigation lowers farm instability is found in nine out of eleven states. For alt the eleven states taken together, the coefficient of variation of detrended output is 5 A per cent for the irrigated segment as against 11.4 per cent for the unirrigated segment Quite expectedly, the stability gain in yield due to irrigation is much more than the corresponding stability gain in crop area. It is in the two high rainfall states of Bihar and Madhya Pradesh that irrigation fails to show any moderating influence on agricultural instability.

Management of Groundwater Resource-Direct versus Indirect Regulatory Mechanisms

Direct versus Indirect Regulatory Mechanisms B D Dhawan Excessive groundwater exploitation has become a matter for concern, especially among hydrogeologists and financial institutions which massively support groundwater development in India. Direct, regulatory measures on the lines of the model bill suggested by the centre, namely, 'The Groundwater (Control and Regulation) Bill* of 1974, have yet to be enacted by the state legislatures. And the indirect measures, such as restricting institutional finance and electricity connections in the endangered areas, have proved rather ineffective. The author thinks that in the particular conditions of relatively small and fragmented landholdings in India legislative enactments are of little practical value and, therefore, main reliance has to continue on indirect measures. And here we need to broaden the set of measures.

Irrigation Impact on Farm Economy

B D Dhawan The main conclusion, emerging from a limited probe into the sample field data of four states of Maharashtra, Tamil Nadu, Punjab and Uttar Pradesh is that the on-farm benefits from a unit of irrigated area need not rise with the size of a farm holding. Small farmers can gain, acre for acre, as much benefits from irrigation as do large farmers. This is borne out by survey data pertaining to Punjab and Tamil Nadu states.

Irrigation Performance during Drought

B D Dhawan The extent to which agricultural growth is accompanied by increasing instability in crop output has been adequately probed. But the behaviour of crop output during drought years, both under irrigated and unirrigated conditions, has not been subjected to any thorough analysis.

Impact of Irrigation on Instability in Farm Output-A Case Study of Tamil Nadu State

in Farm Output A Case Study of Tamil Nadu State B D Dhawan This paper investigates whether irrigation mitigates instability in agricultural production through a case study of Tamil Nadu. It tries to bring out that inter-period comparison in output instability

Underutilisation of Groundwater Resources- A Case Study of East Uttar Pradesh

A Case Study of East Uttar Pradesh B D Dhawan East UP is an important plains region of the vast Gangetic basin that is known for its bounty of water resources, both surface and below ground. Its groundwater potential is today of the order of 2.5 million hectare-metres, adequate for year-round multiple cropping on the 6 million hectare area of the region. At present, barely two-fifths of the groundwater potential has been tapped and two-thirds of the cropping is done under unirrigated conditions.
