KOLKATA 6 April: The West Bengal Pollution Control Board (WBPCB) is going to provide technical assistance to farmers in the Aila-affected regions where they could not sow seeds due to high salinity.
The initiative was taken after it was found that 80 per cent of the farmers of that area are moving to other regions as they failed to sow seeds in the Sunderbans after the storm.
As scientists worry about the prospect of a catastrophic flood from Lake Sarez in the Pamir Mountains, agricultural communities on the plains below face a very different problem. This arid region in Central Asia has inherited a set of resource blunders made decades ago by the Soviet Union. And since the Soviet collapse in the 1990s, competition for fresh water has increased.
In the present study, efforts have been made to identify and map areas affected by various soil degradation processes in Hanumangarh district of western Rajasthan. Soil degradation processes were identified by using IRS-1B satellite image of the year 1998, SOI topsheets, ground truth verification and soil studies.
Desertification is the process of land degradation in arid, semi-arid and dry-subhumid areas. This communication describes the classification system, methodology and the results of desertification and land degradation status mapping carried out for the entire country on 1 : 500,000 scale using multi-temporal
Resourcesat AWiFS data.
The ongoing global climate change (CC) has already caused a grave concern to the country's agriculture, irrigation, navigation, ecology, bio-diversity, weather, environment and underground water levels, concerned experts said.
