Waterlogging and salinity have afflicted about million ha of irrigated lands in Pakistan which has reduced production potential of the Indus Basin by 25 %. Over the last 40 years, Pakistan has adopted engineering, reclamation, and biological measures to rehabilitate these by: 1. the problems emerging as a consequence of over-irrigation to agricultural lands. Amongst various measures adopted, the subsurface drainage technology was introduced by WAPDA in Pakistan about three-and-a-half decades ago to combat the twin menace of waterlogging & salinity. As such, Government of Pakistan has invested considerable funds (~Rs
Waterlogging and salinity have plagued irrigated agriculture in the Indus Basin for the past years. Approximately 6 million ha (% of total irrigated area) experience these twin problems. As a result, the production potential of the Indus Basin has been reduced by 25%.Cited by: 1.

The causes are fairly well known and well. How is International Waterlogging and Salinity Research Institute (Lahore, Pakistan) abbreviated?

7-Waterlogging and salinity 1. Seepage Bibliography on waterlogging and salinity problems in Pakistan book water from canal system The main cause of waterlogging in pakistan is seepage of water from network of canal system% water is lost from main canals,seeps through soil and rised the ground water.
In some cases the water table has risen upto root zones or even surface of soil. The irrigation system in Pakistan has brought great benefits to many people.
Dependence on the natural hydrological system has been minimized and new settlements in canal irrigated areas have been established.
However, the canal system has been accompanied by problems, which are increasingly difficult to overcome. Water logging and salinity are two of. Water Logging and Salinity in Pakistan • Water logging represents the situation whereby the underground water comes on the surface of the land and in certain cases it gathers on the ground level of the lands and it may assume the shape of streams.
Water Logging and Salinity in Pakistan • As a result, the lands become uncultivable. In Pakistan, salinity is one of the country’s most serious environmental problems, caused by human-induced soil erosion and long-term mismanagement of various agricultural practices (World Bank, ). Not only the soils but also the irrigation water itself is one of the major source of salinity in the arid region (Rus et al., ).
Among. Waterlogging and salinity have plagued irrigated agriculture in the Indus Basin for the past 30–40 years. Approximately 6 million ha (35–40% of total irrigated area) experience these twin.
PAKISTAN'S agriculture largely suffers owing to waterlogging and salinity in cultivable land. Pakistan has been acknowledged for having a well-knit irrigation system.
While waterlogging and salinity remain major issues across the country, the most terribly affected province in the country that faces these twin issues is Sindh.
About 53 percent of the total Author: Khushbakht Siddiqui. A salinity survey conducted in by the Soil and Reclamation Directorate of the Water and Power Development Authority (WAPDA) showed that 27% of the area was salt affected.
The government of Sindh has recently banned rice cultivation in command areas of the canals on the left bank of the Indus to control waterlogging and salinity. Irrigation Management in Relation to Waterlogging and Salinity: Precis for a Research Agenda in Pakistan INTRODUCTION WATER MANAGEMEN IN agricultural production in Pakistan isaccomplished primarily through a combination of irrigation anddrainage.
These two activities provide an effective control system for the provision and mainte. Punjab are strongly affected by salinity and water logging (Khan, ). Similarly in Khyber Pakhtunkhwa Mha of land is affected by salinity (Qureshi and Lennard, ).
Approximat hectare of arable land in Pakistan is lost annually to cultivation due to salinity, and it is suggested that two tons of salt are added to eachFile Size: KB. Pakistan possesses the biggest single gravity flow irrigation network in the world capable of handling over million acre-ft (40 million ha m) of water annually to irrigate an area of about million ha.
However economic efficiency of the water system is very low, due to excessive water losses, low irrigation efficiency, inadequate drainage, fragmented land holdings, waterlogging and Cited by: 3.
Together waterlogging and salinity rob Pakistani farmers of about 25% of their production potential for major crops, valued at an estimated cost of Pakistan Rupee 14 billion (1 US$ ≈ 58 Pak Rs.
in ) annually in lost production (Haider et al., ). Waterlogging and salinity have adverse social and economical effects on rural communities Cited by: This paper reviews sources, causes and extent of salinity and waterlogging problems in the Indus Basin.
Measures taken to overcome these problems over the last four decades are also discussed. The results reveal that the installed drainage systems were initially successful in lowering groundwater table and reducing salinity in affected areas.
Pakistan has a total of about million hectares affected by salinity to varying degrees. It can be reclaimed and hopefully the NDP would produce a complete and durable drainage system to remove. Downloadable. Irrigation plays a crucial role in improving agricultural productivity, it has resulted in waterlogging and salinity problems in Pakistan due to both water seepage from canals and overdoses of water encouraged by inappropriate water pricing practices.
As many as million hectares of land forming 13 percent of the cultivated area in Pakistan suffer from an acute problem of. This paper describes the processes by which irrigation development may induce waterlogging and salination of land.
The harm done by this type of waterlogging and salination is briefly discussed as well as the available remedial measures.
Three illustrative cases are also described. Finally, some specific suggestions are made on the coverage of irrigation induced waterlogging and salination Cited by: The dry-drainage system was simulated for the Lower Indus Basin in Pakistan, where shallow saline watertables, intensive irrigation and high evaporative demand exist.
Almost one-third of its available cultivated land has already been abandoned due to waterlogging Cited by: Drainage, waterlogging, and salinity Article in Archives of Agronomy and Soil Science 60(12) April with 1, Reads How we measure 'reads'Author: Mohammad Valipour.

INTRODUCTION Whereas irrigation plays a crucial role in improving agricultural productivity, it has resulted in waterlogging and salinity problems in Pakistan due to both water.
The rise of water table to the surface level is called water logging and the appearance of salty patches is called salinity. It is mainly the outcome of canal irrigation in Pakistan. with the introduction of perennial canal water was available through out the year, resulting in the rise of water table.
salt in the soil also rise to the surface with water table.(water evaporate and salt. Africa. These problems have a great impact on soil fertility which in turns has a great effect on soil productivity.
Thus, this paper reviews water logging and salinity as irrigation problems in South Africa with emphasis on Vaal harts Irrigation scheme (VIS). An estimated % ofha of South Africa soils were discovered to. Open Library is an open, editable library catalog, building towards a web page for every book ever published.
