2. <strong>Irrigation</strong>-induced environmental problems like salinity <strong>and</strong> waterlogging are lesser<br />
where WUAs are active.<br />
3. WUAs enable farmers to improve crop yields, through better water management.<br />
Methodology<br />
Tungabhadra, one of the major irrigation projects in Kamataka, has been selected <strong>for</strong> the<br />
study. The selection of the sample was based on stratified sampling, the strata being<br />
distributary, outlet, village <strong>and</strong> farm households. Size of the distributary in terms of<br />
designed discharge of water, area irrigated, crops grown <strong>and</strong> extent of area affected by<br />
waterlogging, salinity <strong>and</strong> alkalinity were the main criteria <strong>for</strong> selection of the distributary<br />
<strong>and</strong> the outlets <strong>for</strong> the in-depth study. The presence of a WUA has been one of the criteria<br />
<strong>for</strong> selection of the outlet. Based on these criteria, two outlets under the 31/2 Sub<br />
Distributary (DY) trom Tungabhadra Left Bank Canal (TLBC) were selected. The selection<br />
was based on purposive sampling, the purpose being the presence of a WUA in one outlet,<br />
<strong>and</strong> the absence of a WUA in another outlet. The approach adopted <strong>for</strong> the study is,<br />
there<strong>for</strong>e, cross-sectional i.e. with <strong>and</strong> without. The villages selected <strong>for</strong> the study are<br />
Gundur (with WUA) <strong>and</strong> Hagedal (without WUA) coming under the comm<strong>and</strong> of Sub DY<br />
3112.<br />
Selection of farmers<br />
A brief survey of farmers having l<strong>and</strong> in Hagedal <strong>and</strong> in Gundur, the members of WUA<br />
coming under the comm<strong>and</strong> of 31/2 was conducted to obtain detail cd in<strong>for</strong>mation about the<br />
various aspects of the comm<strong>and</strong>. A sample of 25 percent was drawn <strong>for</strong> an in-depth study.<br />
The sample size is 69 <strong>and</strong> 47 farmers in Hagedal <strong>and</strong> Gundur, respectively.<br />
The distributary in both the villages was divided into three parts, i.c. head, middle <strong>and</strong> tail<br />
end. The total outlets were put into three categories. In doing so we had discussions with<br />
farmers <strong>and</strong> the field level irrigation officials. A sample of 25 percent was drawn from each<br />
outlet. Each outlet was also divided into head, middle, <strong>and</strong> tail portions. The number of<br />
respondents from each portion was drawn r<strong>and</strong>omly. The outlet-wise position of total<br />
farmers <strong>and</strong> the farmers drawn trom different positions <strong>for</strong> the sample is given in Tables 3.1<br />
