Global map of salt-affected soils
The Food and Agriculture Organization (FAO) launched the Global Map of Salt-Affected Soils, a key tool for halting salinization and boosting productivity. The map estimates that there are more than 833

Managing salt affected lands through local short/long term field experiments - Lessons learnt
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.

Present Status of salinity rise in Sundarbans area and its effect on Sundari (Heritiera fomes) species
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

Environmental degradation due to marble mining dust on the soil quality of Makrana, Nagaur (Raj,), India
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.
