Krishna Basin development: Interventions to limit downstream environmental degradation
Since India gained Independence, the Krishna basin has seen an increasing mobilization of its water resources. Warnings of basin closure (minimal flow to the ocean) emerge during dry periods. Basin water development and local rural dynamics have led to a degradation of downstream ecosystems manifesting itself by salinizing soil and groundwater, increasing pollution, making mangroves disappear, and desiccating wetlands. Reversing this evolution requires the formal recognition of the environment as a water user in its own right and the implementation of an environmental water provision.

Geoinformatics as a tool for the assessment of the impact of ground water quality for irrigation on soil health
Secondary salinisation is the most harmful and extended phenomenon of the unfavourable effects of irrigation on the soil and environment. An attempt was made to study the impact of poor quality ground water on soils in terms of secondary salinisation and availability of soil nutrients in Faridkot district of Punjab of northern India.

Alleviation of adverse effects of salt stress on sunflower by exogenous application of Salicylic Acid
Spraying plants with the hormone salicylic acid can help them withstand excess salt in the soil, report scientists in Pakistan. External application of the chemical improves the growth of salt-stressed sunflower plants and leads to higher yields.

Worrying phenomenon
Studying the data spread over 23 years (1981-2003), the Food and Agriculture Organisation has concluded that 24 per cent of the global land area has degraded. This is over and above the extent of land that had already degraded. The situation has only worsened since 1991 when the previous assessment was made. According to the FAO, in India about 592,000 square kilometres of land has deteriorated

High tide threatens farmers' fortunes as fields turn saline
Farmers along the Gujarat coast should have been rejoicing at the prospect of a timely monsoon. Instead, they have suddenly become gloomy after unnaturally aggressive high tides have filled their fields and ponds with saline seawater. Many fear a drinking water crisis as their ponds, meant to store fresh rain water, are now brimming over with saline water. Farmers say they may not be able to cultivate anything for years together as their fields have become saline.

Erosion driving people to other States
The living condition of the people of Paschim Ratiadaha part-II village under Bisondoi gaon panchayat in the far western part of the Indo-Bangladesh border in Golokganj LAC of Dhuburi district are in a deplorable state as the villagers are yet to see the development even after six decades of India's Independence. The heavy-erosion of the river Gangadhar has made more than 300 families of Ratiadaaha part-II village homeless and has devastated their cultivable lands. As a result, the homeless families have to take shelter on roads and dykes.
