In the present study, a Semi-automated Empirical Methane Emission Model (SEMEM) has been developed and used for estimation of methane from wetlands using MODIS (MODerate resolution Imaging Spectroradiometer) data. The model has two key factors, namely temperature and productivity.
Agriculture must supply all people with enough food to prevent widespread hunger and starvation. However, food security is aggravating day by day, resulting in more number of undernourished/malnourished persons in the world. The ever-increasing population in the developing and less developed countries is also a major constraint.
Sustainable agricultural productivity over the long term was not a major issue in the 1960s and 1970s, as food resources did not appear to be threatened1. The attention was on producing enough food to overcome the immediate problems of food deficit.
Hurricane Hannah hit Hiati and Ike struck the Texas Gulf coast, as the Atlantic Ocean continues to churn more storms, leaving people dead and displaced. Back home, it was the overflowing Kosi river that had displaced 25 lakh people in Bihar and 12 lakh in Assam.
The Araku Valley, comprising Anantagiri and Sunkarimetta Reserved Forest, is one of the rich biodiversity areas in the Eastern Ghats of India. The proposed bauxite mining activity by Andhra Pradesh Mineral Development Corporation Limited in these areas would not only wipe out the virgin forests, but also destroy the pristine habitats of several endangered flora and wildlife.

Bt cauliflower is one of the important genetically modified
(GM) crops approved for Biosafety Research Level 1 field trials in India. Towards developing reliable qualitative and quantitative PCR methods for detecting and monitoring GM crops, in the present study, molecular detection of cry1Ac gene CaMV 35S
Antarctic sediments dating from 30 million to 145 million years ago (a time during which the vast Antarctic ice sheet is thought to have formed and the Transantarctic mountains pushed up) have been a valuable source of information about the forces that changed the climatic conditions of the Antarctic continent.
High fluoride level in drinking water causes different kinds of toxicosis in humans and animals. The present investigation was undertaken to observe different forms of enamal mottling in mature and immature domestic animals consuming water containing fluoride below the maximum permissible level.
