In Bangladesh, major irrigation project covered only about 10% of irrigated area while minor irrigation system covered 90% in private sector. Presently, under minor irrigation system 50-60% of lifted water is lost due to lack of appropriate technical know-how in water management, unplanned & improper size of irrigation canal, poor control structure and unplanned drainage system.
Presently in Bangladesh 220 hac. land is being lost from Agricultural use per day due to rapid spread of inhabitation and industrialization. So, there is no other way but to intensify use of our existing cropland. Besides this, almost 30-35% of animal power which increases up to 45% is being deficit in the crop field at the pick period. To recovery this deficit the existing numbers of Tractor and Power tiller are not sufficient and needs to be increased. Again at the pick period of land preparation and harvesting due to scarcity of labour loss of time is occurring. So use of Agricultural machinery in every stage of cultivation can save the mentioned time which can create a scope of cultivating another new crop resulting increase of cropping intensity to a significant level.
According to views of Water specialist in aspect of dangerous threaten like arsenic contamination and severe earth quake, excessive withdrawal of ground water should be stopped. At the same time give emphasis on optimum and multiple use of ground water. In this perspective, construction of low cost deep tube well, irrigation by buried pipe system, domestic water supply with excess water- a model of multipurpose use of water developed by Rural Developed Academy (RDA) would be a suitable solution.
Again, though surface water availability in the country during July to September comes to abundant condition due to rainfall but it turn over to almost nil condition in dry season. Hence, re-construction & re-excavation of Khal, water bodies, ponds may be a timely step. Again, a huge amount of cropland cannot be brought under the control of cultivation due to adverse effects of drainage & water logging. Introducing low cost underground drainage system will allow to expansion of command area of cropland as well as increase production significantly.
Implementation of these activities has been carried out under the supervision of Water Management and Agricultural Engineering Wing funded by ASSP and its follow-up ASIRP Projects of DAE. It may be mentioned that according to ASIRP; IDA/DFID/FAO/GoB supervision implementatioin review mission's recommendations, the findings are shown as - "The pilot programme could prove that with the adoption of simple On-Farm Water Management Technologies Irrigation coverage could be increased by 29% and as such the supervision mission recommended to disseminated the new technologies to all irrigated area of the country for which a country wide programme is necessary".
With a view to discharging the modern and latest technologies developed by research an urgent need of implementation of this proposed project has been identified.
The PCP has been evaluated in the evaluation meeting of Planning Commission held on 25/07/04 and the PCP has been discussed and recommended inthe pre-ECNEC meeting held on 23/02/05.After that the PCP has been approved in the ECNEC meeting held on 31/05/05. |
