IRRIGATED LAND
BARRAGE
In Western Pakistan the chief method of irrigation is by constructing perennial canals which take water from reservoirs that are formed by building barrages on the rivers. By this method, land between the rivers or the doabs can. be irrigated without depending on the natural flow of the river. Closely linked with many os.. the irrigation schemes are hydro-electric power. projects. Examples of such multi-purpose undertaking are: Wardak project in the North-west Frontier Province, the Kangla Dam on the River Jhelum.
Water is of utmost importance to the Weatera Pakistan as agriculture in the major occupation in this region, Formerly, agriculture depends mainly upon natural rainfall and the effect of the failure of the monsoon rains would spell disaster to the farmer in bhia region. In the early fifties, Pakistan has to import a large amount or wheat simply because the rainfall is below that of the average. Not only does the irrigation; scheme supplement the normal amount of rainfall- but also vast tracts of formerly barren land are brought under cultivation. It is estimated that the Thal project in north-western Punjab alone would led to the development of 2 million acraN semi-desert Land. Most of the modern schemes are dual or multi-purpose schemes and an a result, the installed electric power capacity of Pakistan has dacreased many folds. However, irrigation does bring about probleme of waterlogging and salt accumulation which are affecting many thousands of acres of land in Punjab

(b) Using some of the information given in
Figures 5 and 6, give reaona for the growth] of the port of Mombasa.
Mombasa enjoys a very good position from military point of view as it is surrounded by water on the eastern and western side, It is virtually impregnable from attack on land since the approaches are very narrow. The site of an on for apporti thon argument very well. Later on with the completion of the Kenya-Uganda Railway in 1910, the hinterland was vastly extended to include the whole of Kenya as well 88 Uganda, Suffice to say that, whila formerly the hinterland of Mombasa includes only the narrow coastal strip which producea coconuts and sisal, the extension of the hinterland brings new products such as pyrethrum, coffee, and cotton to the port of Mombasa from Uganda and North-western Кедуа..
If the site of Mombasa is examined carefully, we could easily find that it possesses the advantage of having Kilindini Harbour which is the finest harbour in the whole of East Africa. Coupled with a good natural harbour, the entrance to the port is free of coral reefs and mangrove. swamps which may seriously affect navigation. In addition to a railway, Mombasa is in constant contact with other parts of the world by means of air transport. (An aerodrome can be found in the western part of the oity.) As a matter of fact, Mombasa lies along the major ocean route along the. Western Indian Ocean and it is not without ground to auggest that Mombasa may also serve as a port- of call.
