in yield. This may be due to different water management practices adopted in both the<br />

villages. In Gundur, it is the assurance <strong>and</strong> timeliness of supply of water by the WUA,<br />

which has enabled the farmers to use water according to the needs of the crop (see Table<br />

7.6). In Hagedal, where there is no WUA, malfunctions regarding water use are rampant<br />

(see Table 7.7). This has not only created adverse effects <strong>for</strong> the soil but also leads to<br />

decline in yield in the affected soils.<br />

Table 8.4: Decomposition of Differences in Yields in Affected L<strong>and</strong>s <strong>and</strong> Good<br />

L<strong>and</strong>s into Affected L<strong>and</strong> <strong>and</strong> Input Changes in Gundur <strong>and</strong> Hagedal<br />

Source of change Gundur Hagedal<br />

Further, to examint: the extent of impact of difference in l<strong>and</strong> quality on the average yield,<br />

we have undertaken a decomposition analysis. Here we estimated equation (5) <strong>for</strong> both the<br />

villages. Since gypsum is used only in the affected l<strong>and</strong>s, the production function has been<br />

I<br />

re-estimated <strong>for</strong> affected l<strong>and</strong> <strong>for</strong> the purpose of the decomposition analysis. Given that the<br />

elasticity of gypsum was insignificant in both the villages, there was not much difference in<br />

the elasticity of other variables in the production function when it is excluded. With the<br />

help of the elasticities <strong>and</strong> the mean values of each variable we have decomposed the whole<br />

effect into l<strong>and</strong> effect <strong>and</strong> input effect <strong>and</strong> these are presented in Table-8.4. It may be noted<br />

that the percentage decline in the yield from affected l<strong>and</strong> in relation to the good l<strong>and</strong> of<br />

Gundur (-12.07 percent) is less than Hagedal (-21.45 percent). This could be attributed to<br />

better water <strong>and</strong> l<strong>and</strong> management in Gundur where the WUA is active.<br />

The impact of l<strong>and</strong> quality on yield reduction, keeping inputs constant, is relatively high in<br />

Gundur (-2.5 percent) compared to Hagedal (-I percent). This indicates that with the same<br />

level of resources compared to waterlogging <strong>and</strong> salinity free areas, the gross output would<br />
