Climate change, mitigation and adaptation with reference to agriculture over the humid tropics - Winter School on Impact of Climate Change on Indian Marine Fisheries held at CMFRI, Cochin 18.1.2008 to 7.2.2008 -Winter School on Impact of Climate Change on Indian Marine Fisheries

The Bali road map under UNFCCC highlighted the conclusions of IPCC on climate change across the World. It indicates that the global warming is real. The Polar ice is melting and sea level will increase. One-third of our plant and animal species are likely to vanish. There will be famine around the world, particularly in Africa and central Asia. The Reduction of Emissions from Deforestation and Degradation (REDD) in developing countries is on top priority as deforestation alone may cause 20 to 25% increase in greenhouse gas emissions in the atmosphere. The second major issue is on “Adaptation Fund” designed to help developing countries dealing with impact of climate change. Therefore, it is pertinent to follow the guidelines at the regional scale so as to mitigate the ill effects of climate change on war-footing

Rapid Determination of Copper in Copper Ores

Low grade copper ores and copper ores in association with considerable quantities of other elements such as iron, lead, zinc and vanadium require a separational step wherein copper is generally seperated as sulphide either with sodium thiosulfate or with thiocetamide. In these methods the precipitated copper sulfide is ignited to cupric oxide, dissolved in dilute nitric acid and titrated idometrically. In a recent methorl wet oxidation of precipitated copper sulfide is effected with nitric acid ,and perchloric acid and titrated with disodium ethylene diamine tetraacetate (EDTA). The authors' work on the beneficiation of low grade copper ores. and extraction of copper, from these ores has necessitated developing a rapid and accurate method for the determination of copper. A separational step wherein cupric ion could be preci-pitated as cuprous oxide has been introduced to avoid ignition of copper sulfide to cupric oxide, which is time consuming
