<strong>of</strong> the important studies on the performance <strong>of</strong> irrigation In India has been presented in what follows. 2.1 Studies on impact <strong>of</strong> Irrigation The positive effect <strong>of</strong> irrigation on the farm economy is widely recognised among the researchers. However, researchers, by and large, are faced with the problem <strong>of</strong> decomposing the irrigation effec{ where a host <strong>of</strong> complementary and intervening variables are to be considered. For, the productivity augmenting effect <strong>of</strong> irrigation is determined by various factors, such as change in land use, intensity <strong>of</strong> cropping. efficiency in the use <strong>of</strong> fertiliser and nutrients, quality <strong>of</strong> irrigation (quantum, assurance and timeliness In supply), agro-climatic conditions, pattern <strong>of</strong> rainfall and its distribution. bio-chemical technology. seed varieties. chemicals and other inputs. The impact <strong>of</strong> irrigation with particular reference to canal irrigation, on production, productivity and income from farming has, however, been analysed by many researchers, especially since independence. These studies have found positive association between income and the farm size in the canal irrigated areas. apart from stabilisation <strong>of</strong> farm output (Dhawan 1982, 1985, 1988; Rao el ul.. 1988). The increase in output per unit <strong>of</strong> irrigated area, though obvious. has I Dhawan, who has extensively addressed the question <strong>of</strong> impact <strong>of</strong> irrigation, with particular reference to canal irrigation, suggests a pragmatic approach in analysing the irrigation impact. lie concludes that: "One interesting way <strong>of</strong> skirting the problem <strong>of</strong> output decomposition in the case <strong>of</strong> irrigation and its complementary inputs is to take the logic view that irrigation. being an enabling factor for the use <strong>of</strong> its complementar) Inputs like chemical fertilisers and HYV seeds. ought to get the entire credit for whatever rise in output occurs in the wake <strong>of</strong> a switch over from dry to irrigated farming" (Dhawan, 1988: 31). 37
een brought out by many scholars in different agro-c1imatic regIons (Vaidyanathan, 1987; Ray, 1991; Dhawan, 1992; Vaidyanathan et a!.. 1994). Based on the source-wise ratio <strong>of</strong> net irrigated to net sown area across the major states in India. Vaidyanathan (1999) finds that the coefficient <strong>of</strong> variation (CV) has fallen from 77 per cent in the early 1960s to 54 per cent in the late 1980s. This reduction in regional disparities has been largely due to a more even spread <strong>of</strong> canal irrigation stimulated by public investment. The FAO study shows that the well-endowed green revolution areas (in terms <strong>of</strong> good soils and assured irrigation) have experienced tremendous decline in poverty levels owing to consistent agricultural growth. The elasticity <strong>of</strong> cropping intensity with respect to irrigation has been around 0.3 and <strong>of</strong> land productivity with respect to irrigation has been above 0.5 (FAO. 1993. as cited in Alagh. 200 I) However, the impact <strong>of</strong> spatial and temporal variations in rainfall, spread <strong>of</strong> irrigation and its quality and fertiliser on productivity <strong>of</strong> crops estimated through multiple regressIon analysis by some <strong>of</strong> the scholars. has not been conclusive and convincing (Mukherjee and Vaidyanathan. 1988; Vaidyanathan et (1/ (1994). This is mainly because <strong>of</strong> the estimated coefficients not showing any pattern owing to the infirmities in irrigation statistics. This shows the inadequacy <strong>of</strong> data available for reliable estimates <strong>of</strong> irrigation impact. Moreover. the multiple regression models implicitly assume linear additive relations between input and output. which is unrealistic in view <strong>of</strong> the complex. non-linear and interactive relationship between variables (Vaidyanathan. 1999:80). 38
