There are two broad categories of marginal-quality water: wastewater generated by the domestic, commercial, and industrial
sectors; and saline water from agricultural drainage systems, surface runoff, or pumped from overexploited aquifers. Millions of small-scale farmers around the world irrigate with marginal-quality water, often because they have no alternative.

A Decision Support System (DSS)on bio-drainage for reclamation of salt affected and waterlogged lands was developed using Visual Basic (VB) protocols. The DSS permits the user to interactively enter input information viz., the area available for plantation, average annual rainfall, initial and desired water table depth, soil type and the plantation type.

ABOUT 200 acres of land in the Boro Beel area at village Ratugram under Durgapur upazila in Rajshahi remained uncultivated for the last several years due to water-logging. Local people said the water stagnancy created in the bil due to closure of the water drainage channels, depriving local farmers from cultivating crops. The huge land of the water body remains under water every year because of floods and heavy downpour in the rainy season in the absence of sewage outlet, local farmers said. Earlier, two canals were dug in the southern and northern sides to drain out water from the bil. But several influential local people filled up the canals with earth in 1997 and started cultivation of onion, IRRI paddy on the land, creating water stagnancy in the bil area. Many farmers of Ratugram, Kayamajampur, Badail and Ujalkalsi villages have their land in the bil and are being deprived of cultivating crops. The farmers said the authorities concerned should take initiatives for re-excavating the closed canals. 'If the authorities take immediate step, we could cultivate boro paddy on our land during the current season,' said a farmer.

Bihar's fall from a state with healthy socio-economic indices to now being one of India's least developed states has been drastic. The major failures lie in governance, and in the downfall of the agricultural sector. A study of the perennial story of flooding and relief measures and the consequent failure of agriculture show how disorganised the state of affairs is. Feb 16-22, 2008

Poor management of irrigation water and inadequate drainage system in plains have made vast tracts of agricultural land unproductive due to waterlogging and high moisture content. Integrated development of such waterlogged ecosystem has been taken up under NWDPRA (National Watershed Develpoment Project for Rainfed Areas) with the twin objectives of sustainable production of food, fruit, fuel and bio-mass and restoration of ecological balances with the watershed.

A detailed hydrogeological investigation was carried out in parts of the Central Ganga Plain, India, with the objective of assessing the aquifer framework and its resource potential. The area was studied because of its dual hydrogeological situation, that is water logging and soil salinization in the canal command areas and depletion of aquifers in the western part of the basin. A comprehensive investigation of the aquifer system between the Ganga River and Kali River revealed its lateral and vertical dimensions and hydrogeological characteristics.

Agriculture plays a significant role in the Indian economy. Food production in India has increased from 51 MT in 1950-51 to 204.6 MT in 2004. While Green Revolution has been one of the greatest success stories of India with its dramatic impact on food security, environmental concerns have been growing rapidly all over the world.

Irrigation water security is vital both for livelihood and food security. While the country has made large investments in the augmentation of water supply, there have been no commensurate efforts in the management of demand and in the promotion of efficient and economic water use. This report draws attention to the scope available for improving the efficiency of use of irrigation water in a manner that both the productivity and profitability of farming are enhanced.

The scale of displacement under Polavaram project is unprecedented and government has no proven capacity or commitment to rehabilitate the displaced. This project will not only hit lakhs of people, but also endanger the delta (with excessive water logging). So, government should give up the entire project
