Last Saturday we had a study tour to Gadap Town Karachi on behalf of Sociology Department, University of Karachi, Gadap Town is a town in the northwestern part of Karachi with the Hub River on its western limits also forming the provincial border between Sindh and Balochistan, while to the north and east are Dadu District and the Kirthar Mountains.
Dr.Prof.Sobia Shaizad and Dr.Kauser Parveen were the organizers of the tour and they introduced the Gadap community to the students. The students were given a task to observe the Gadap Community’s Social Issues and challenges in their life. I found the community resemble to other rural areas of Pakistan but the only thing which attract and was new to me is their Irrigation System i-e ‘’Drip Irrigation System’’.
“Drip irrigation is an efficient and economical method of watering. Used commonly in dry regions with scarce water resources, the use of drip irrigation is increasing in the Northeast. This irrigation method is typically more than 90% efficient at allowing plants to use the water applied.’’
We visited the field areas of the Gadap town and got chance to interact with the residents and farmers of the town. According to them this system was introduced to them during 2002 in the government tenure of Gen-Musharraf. We were not able to cultivate crops because of the lacking of water source in the town and this system had changed our life, he further added. Small Dams were installed at the corner of every field to store and supply water to the crops. According to one of the farmer he said that they are able to cultivate crops after every two years, when asked why then he gave a very good reason that it depends on the soil’s fertility and if you will cultivate any crops during the break season then you will be not able to get good result of the crops.
Most of the people relay on the rain water and there is no any alternative source of water to them. The Government should introduce Drip Irrigation System to all those areas where they are not able to irrigate because of scarcity of water buried lands.
I have noticed and observed many advantages and disadvantages of the systems.
The advantages as per my observation are there is minimum chance of water wastage and you can use the water on greater level, Fertilizers can be use with high efficiency. The most important thing is that it is not important to level the field and which can save time of farmers. There is less chance of fertilizer wastage Energy cost can be reduced as it operated in lower pressure then other irrigation system.
I haven’t notice any disadvantages of the Drip Irrigation System during the visit but the Local people mentioned some. According to them it is expensive especially the initial cost is high and the lifetime of the tube used in the irrigation system can be shorten by the direct sun rays and the most important thing is that high Skills labors are required.
