The above issue <str<strong>on</strong>g>of</str<strong>on</strong>g> c<strong>on</strong>siderable amount <str<strong>on</strong>g>of</str<strong>on</strong>g> l<strong>and</strong> degradati<strong>on</strong> as reported in<br />

the Kuttiadi irrigati<strong>on</strong> project points to the necessity <str<strong>on</strong>g>of</str<strong>on</strong>g> a realistic estimate <str<strong>on</strong>g>of</str<strong>on</strong>g> the<br />

problem affected areas in irrigati<strong>on</strong> comm<strong>and</strong>s in Kerala in order to reflect <strong>on</strong> the<br />

prot-dem <str<strong>on</strong>g>of</str<strong>on</strong>g> capacity under-utilisati<strong>on</strong> in irrIgati<strong>on</strong> projects. The reported paddy area<br />

in Irrigati<strong>on</strong> projects is to be rea,sessed to bring out the actual irrigable area.<br />

There are also evidences <str<strong>on</strong>g>of</str<strong>on</strong>g> shrinking capacity <str<strong>on</strong>g>of</str<strong>on</strong>g> some <str<strong>on</strong>g>of</str<strong>on</strong>g> the reservoirs due<br />

to sedimentati<strong>on</strong>. For instance. the original capacity <str<strong>on</strong>g>of</str<strong>on</strong>g> the Malampuzha reservoir<br />

was 228.40 milli<strong>on</strong> cU.m. according to the project report. A study c<strong>on</strong>ducted by the<br />

Kerala Engineering Research <strong>Institute</strong> (KERl, 1978) shows that the capacity had<br />

reduced to 220.15 milli<strong>on</strong> cU.m as a result <str<strong>on</strong>g>of</str<strong>on</strong>g> sedimentati<strong>on</strong>. Another study by KERI<br />

( 19K3), reveals that the average annual sedimentati<strong>on</strong> rate in Peechi reservoir was<br />

0.91 per cent <strong>and</strong> this appears to be higher than that <str<strong>on</strong>g>of</str<strong>on</strong>g> the sedimentati<strong>on</strong> rate <str<strong>on</strong>g>of</str<strong>on</strong>g> 0.25<br />
