Constitutional provisions related to Environment and its Protection
Constitutional provisions related to Environment and its Protection The protection and improvement of environment is a constitutional mandate. It is a commitment for a country wedded to the ideas of a welfare State. The Indian Constitution contains specific provisions for environment protection under the chapters of Directive Principles of State Policy and Fundamental Duties. The absence of a specific provision in the Constitution recognizing the fundamental right to clean and wholesome environment has been set off by judicial activism in the recent times. Articles 48-A and 51-A. Clause (g) Initially, the Constitution of India had no direct provision for environmental ... Read more
Biogas- principle and process
Biogas- principle and process Principle of biogas production Biogas is generated when bacteria degrade biological material in the absence of oxygen, in a process known as anaerobic digestion. Since biogas is a mixture of methane (also known as marsh gas or natural gas, CH4) and carbon dioxide it is a renewable fuel produced from waste treatment. Anaerobic digestion is basically a simple process carried out in a number of steps that can use almost any organic material as a substrate – it occurs in digestive systems, marshes, rubbish dumps, septic tanks and the Arctic Tundra. Humans tend to make the ... Read more
Energy Efficiency
Energy Efficiency Energy efficiency, means using less energy to provide the same level of energy. It is therefore one method to reduce human greenhouse gas emissions. For example if a house is insulated, less energy is used in heating and cooling to achieve a satisfactory temperature. Another example is installing fluorescent lights or skylights, instead of incandescent lights, to attain the same level of illumination. Efficient energy use is achieved primarily by means of a more efficient technology or process. Energy efficient buildings, industrial processes and transportation could reduce the world’s energy needs in 2050 by one third, and help ... Read more
Climate Change and Its Effects
Climate Change and Its Effects The term climate refers to the general weather conditions of a place over many years. In the United States, for example, Maine’s climate is cold and snowy in winter while South Florida’s is tropical year-round. Climate change is a significant variation of average weather conditions—say, conditions becoming warmer, wetter, or drier—over several decades or more. It’s that longer-term trend that differentiates climate change from natural weather variability. And while “climate change” and “global warming” are often used interchangeably, global warming—the recent rise in the global average temperature near the earth’s surface—is just one aspect of ...

Impact of mining on forest and environment
Impact of mining on forest and environment Mining activities, including prospecting, exploration, construction, operation, maintenance, expansion, abandonment, decommissioning and re-purposing of a mine can impact social and environmental systems in a range of positive and negative, and direct and indirect ways. Mining can yield a range of benefits to societies, but it may also cause conflict, not least in relation to above-ground and sub-surface land use. Similarly, mining can alter environments, but remediation and mitigation can restore systems. Boreal and Arctic regions are sensitive to impacts from development, both on social and environmental systems. Native ecosystems and aboriginal human communities ... Read more
Role of information technology in environment and human health

Water supply and sanitation
Water supply and sanitation Issues related to water supply in India Variability in water availability India faces large temporal variability in water availability, leading to, among other issues, disasters such as floods and droughts. Due to monsoon climate in India, more than 70% of the annual precipitation takes place in a limited period of about four months. In addition to temporal variability, water availability in India also has huge variations with respect to location, resulting in surplus water in some river basins/regions and water scarcity in others. Increasing gap between water availability and demands Population is the key determinant in ... Read more
Eco friendly Technologies
Eco friendly Technologies Rainwater harvesting technology Harvested rainwater can provide a source of alternative water to federal facilities. Alternative waters are sustainable sources of water, not supplied from fresh surface water or groundwater, that offset the demand for freshwater. Rainwater harvesting captures, diverts, and stores rainwater from rooftops for later use. Typical uses of rainwater include landscape irrigation, wash applications, ornamental pond and fountain filling, cooling tower make-up water, and toilet and urinal flushing. With additional filtration and disinfection, harvested rainwater can also be treated to potable standards to supplement municipal potable water supplies to facilities. System Components The major ...
