The quality of water is of immense importance because poor quality ground water is not only a limiting factor in crop production but also its constant and indiscriminate use causes secondary salinization. Therefore, a qualitative water quality survey was carried out to diagnose the salinity for sodicity hazards in ground waters in relation to their suitability for irrigation in Faridkot district (Punjab) having two blocks namely Faridkot and Kotkapura.

In India, chemical degradation of lands is taking place at an annual rate of 0.15-Mha. This is about 10 per cent of the annual global rate of about 1.5-Mha. Due to this, about 3.22 per cent of land area in the country has already become salt affected. Literature search reveals that a myriad of experiments for assessing impacts of varied land/water management strategies on the root zone soil salinization and crop yield reductions have been conducted for managing salt affected lands of India.

The hot arid regions of India in economically and environmentally disadvantaged part of the country with unique problems. These, ecosystems are highly fragile and large liabilities causing severe impediments in development programmes.

The world largest mangroveforest, Sundarbans is situated at the westerncoastal zone of Bangladesh that covers about 40% of the total forest and gives good feedback to the national economy. But for last few years, salinity increasing drastically in this particular region due to sea water intrusion, reduction of fresh water flow and human activities like shrimp farming. In this study both field survey (primary data) and historical
(secondary) data were used to assess the present status of salinity rise in Sundarbans area as well as the effect

Due to the surface mining at Makrana, the flora, hydrological relations and soil biological systems are drastically disturbed. In Makrana the main cause of environmental pollution is marble mining dust particulates and stone crusher dust. Analysis of the samples showed that the soil of Makrana is saline sodic because of high pH value and excess sodium presence. The agricultural field near these marble mines and stone crushers areas show poor growth and yield of crops and vegetable crops was noticed.

Noted environmentalist Sunderlal Bahuguna's fast, undertaken to highlight the dangers of the Tehri dam project, has lasted for more than 40 days. This is the fourth fast by the
