چکیده مقاله:

To combat waterlogging and salinity, initially a number of Salinity Control and Reclamation Projects (SCARPs) were introduced 1960s in Pakistan. And also, surface and subsurface drainage system and biological drain system has been introduced for controlling over twin problem of waterlogging and salinity in the country level. Out of total irrigated area of 16.69 Mha (41.23 Ma), 7.545 Mha (about 45%) has been covered under drainage. Still 9.14 Mha (22.59 Mha) needs to be provided drainage facilities in the irrigation basin system of Pakistan. Institutional Reforms has been introduced within water sector by act 1997, in the Sindh Province Pakistan. Through these reforms Sindh Irrigation & Drainage Authority (SIDA), Area water Boards (AWBs) and Farmers Organizations (FOs) were formed at barrage, main canal and distributaries/ minor levels. Drainage Beneficiary Groups (DBGs) have been made on branch drainage system levels. These reforms have provided good opportunity to the farmers/stakeholders participations in management of Irrigation as well as Drainage system in Sindh province of Pakistan. The Left Bank Outfall Drain (LBOD) which consisted on Spinal drain and Link drain such as the DPOD, KPOD and Tidal Link has been constructed in recently which will receive drain water from left side of Indus River for disposing off into Arabian Sea While Right Bank Outfall Drain (RBOD) is under construction on right side of Indus River which will receive water from Upper Sindh and Balochistan for outfalling in the creek of Arabian Sea. The drainage system/ network in the commanded area of Kotri barrage has been introduced in 1960s. This system covers both sides of Indus Rivers and downstream of Kotri barrage which is under jurisdiction of Districts Thatta, Tando Muhammad Khan and Badin on right and left flanks respectively. There are many constraints/problems for safe removal of drains water, such as, high tide low hydraulic gradient, mismanagement of operation and maintenance of the system, defer of maintenance, not proper collection of revenue and drainage cess, lack of interest of framers/stakeholders towards drainage system, heavy rainfall and cyclone frequently, low crop yield, high value of input, low value of output, shortage of irrigation supply, impact of waterlogging & salinity, fertility of soil, effluent of Sugar mills, polluted of surface canal waters, highly saline groundwater, deteriorating conditions of communication infrastructures, poor living standards, bad environmental impacts over ecosystem, frequently earth due to unstable slopes in silty stretches; these all constraints/problems are brought under discussion during meeting with farmers/stakeholders to address for better management of drainage system in the study area.
