The impact of global warming on agriculture is going to be worse. By Dr. Nitish Priyadarshi On the day you read this, the population of our planet will increase by 230,000 people. Hungry people. In 2012 about 140 million human beings will be born and some 55 million of us will die. That amounts to a net population gain of 85 million – more than 230,000 additional residents of the earth every day of the year. Many of these newcomers will suckle their meals from a mother’s breast for a year or so, but after that it will be up to Mother Earth to provide them food and drink. Our fragile, over extended planet and its hard working human population will have to feed those 230,000hungry people day after day for the next 66 years.   A growing global food shortage has caused prices to double in recent years, and a growing consensus of scientists now blames climate change as one factor in an equation that includes a burgeoning population and increasingly scarce water supplies. More people ar...

With special reference to Jharkhand State of India . By Dr. Nitish Priyadarshi. Palaeoclimatology, the study of climates during the geological past, is one of the most topical areas research in the geoscience at present. The threat of future climate change caused by higher levels of greenhouse gases, which would drastically alter many aspects of our environment, has prompted much research to try to understand how our complex climate system works. Only by understanding how climate has evolved over million of years can we identify important cycles with a frequency in excess of the short climate records we possess. These climate cycles have the potential to have a profound effect on our environment. The determination of past climate parameters by the use of paleohydrologic conditions is an important phase of paleoclimatology. The present climate of any local area, on any continent, and around any lake basin, depends on the same factors which controlled Pleistocene climate. The study of p...

It is definitely going to affect the productivity of the soil and agricultural growth. by Dr. Nitish Priyadarshi  Above photographs shows how the poisonous Parthenium grass is covering the agricultural lands in Gaya district of Bihar state in India . It is definitely going to affect the productivity of the soil and agricultural growth. Gaya is already under the water stress zone which affects the irrigation. Growth of these herbaceous plants   will increase the problem many fold. Lack of awareness among the local people and government agencies had helped these plants to grow rapidly on the vast areas of the district. It will not only affect the agricultural products but also the health of the local villagers with asthma, Allergic, Trinities Sinusitis, dermatitis (type of skin disease) especially among the childrens, Eczema, Allergic papules and all types of Allergic reactions. Parthenium weed's botanical name is Parthenium Hystrophorous . It is a herbaceous plant, and a na...
