Planktonic diversity of a polluted creek system

The demand for power-generating plants has been increasing regardless of several   appeals in energy  conservation. Factors such as urbanisation and industrialisation propel the need for energy production (Singh,  2015).  Consequently, it increases the need for cooling water at various steps during energy generation procedures. In general, water bodies, such as rivers and ocean were often […]

प्रजाति विलुप्ति

पृथ्वी पर पर्मियन युग की जैव विलुप्ति के लिए जलवायु परिवर्तन जिम्मदार

आज से 252 मिलियन वर्ष पहले पर्मियन युग में पृथ्वी पर जीवन के लिए कठिन समय था। उस युग में पृथ्वी पर से अधिकांश जीव नष्ट हो गए थे जिस वजह से इसे ‘महान मृत्यु’ और पृथ्वी का सबसे घातक ‘प्रजाति विलुप्ति’ (Mass Extinctions) की घटना की संज्ञा दी जाती है। जर्नल साइंस में प्रकाशित […]

Ozone Loss

Evidences of Ozone Recovery

The ozone loss process in the stratosphere is relatively well understood and much of the loss is driven by the chemical cycles involving chlorine and bromine compounds, whose abundance peaked around 2000 in the polar stratosphere. With the abatement of atmospheric loading of ozone depleting substances (ODSs) due to the implementation of Montreal Protocol, the […]

GIS and Remote Sensing in Natural Resource Management

Remote sensing and GIS are promising tools for handling spatial and temporal data and help in integrating them for successful planning of natural resources. Remote sensing is the science of measuring the Earth using sensors mounted on high-flying aircrafts or satellites. These sensors collect data in the form of images and provide insights for manipulating, […]
