Government efforts to clean river

Government efforts to clean river Cleaning and rejuvenation of rivers is an ongoing activity. It is the responsibility of the States/Union Territories (UTs) and local bodies to ensure required treatment of sewage and industrial effluents to the prescribed norms before discharging into river and other water bodies, coastal waters or land to prevent and control of pollution therein. For conservation of rivers, this Ministry has been supplementing efforts of the States/UTs by providing fi

Electric Vehicles and Government Policies

Electric car uses alternate fuel electricity instead of petrol or diesel. An electric vehicle, uses one or more electric motors or traction motors for propulsion. There is a growing acceptance for hybrid and electric cars in the country and more and more manufacturers are entering this niche segment with an express objective of lowering the fuel import bill and running cost of vehicles. Conversion of vehicles to electric vehicles has a potential to save fossil fuels worth about $100 b

Aerosol and Climate Change

Aerosol and Climate Change Scientists tracing the concentration, size and evolution of aerosol particles smaller than 3 nanometres at an urban location in India have found frequent formation of sub-3nm aerosol particles in the atmosphere. This has critical importance as a major fraction of these newly formed particles can reach to sizes of cloud condensation nuclei where they have climatic impacts. The formation of small molecular clusters of sub-3nm size is technically called aerosol nu

The IITM-ESM Model (Earth System Model)

The IITM-ESM Model (Earth System Model) Government has developed an indigenous climate model to predict the impact of climate change on monsoon in the country. A state-of-the-art Earth System Model (ESM) has been developed at the Centre for Climate Change Research (CCCR), Indian Institute of Tropical Meteorology (IITM) under the Ministry of Earth Sciences (MoES). The model development was done by the scientists at IITM Pune in collaboration with international research community. Th

Yamuna River Pollution

Yamuna River Pollution Read the complete topic about Water pollution and then read this news for the most retention. The 22 km stretch of Yamuna from Wazirabad to Okhla in Delhi, which is less than 2% of the river length, accounts for about 80% of the pollution load in the river. According to the International Union for Conservation of Nature, an environmental flow is the water provided within a river, wetland or coastal zone to maintain ecosystems and their benefits where there are

Wetlands and Conservation

Wetlands and Conservation Wetlands are the lands transitional between terrestrial and aquatic ecosystem where the water table is usually at or near the surface or land is covered by shallow water. Productivity of Estuaries > Swamp, Marshes, Wetlands > Coral Reefs > Equatorial and Tropical rainforests > Savannah. Definition: Areas of marsh, fen, peatland/ water, whether natural or artificial, permanent or temporary, with static or

Marine Pollution

Marine Pollution What is Marine Pollution? Marine pollution is a combination of chemicals and trash, most of which comes from land sources and is washed or blown into the ocean. This pollution results in damage to the environment, to the health of all organisms, and to economic structures worldwide. Sources of Marine Pollution: Land Based Activities: Dumping of hazardous waste, heavy discharges from industry, inflow of fertilizers and pesticides from agri fields. Pollution f

Elephants

Everything about: Elephants Asiatic Elephant Asiatic Elephant is Endangered in IUCN; Schedule I of Wildlife Protection Act and Appendix I of CITES. Elephants are National Heritage animals. World Elephant Day = 12 Aug, 2017. Elephant Reserves (ER are declared by Center) Singhbhum ER in JH is the 1st ER of India. Karnataka has the highest Elephants followed by Assam & Kerala. Singphan ER = Nag

Green Crackers and NGT

Green Crackers and NGT Green crackers are less harmful and less dangerous than the conventional ones. They are the crackers with reduced emission and decibel level. They are known as 'green' firecrackers because they have a chemical formulation that produces water molecules, which substantially reduces emission levels and absorbs dust. They are cheaper to manufacture and produce 30-35% less SO2 and NO2 emissions. What a

Micro plastics in Ganga

Micro plastics in Ganga An analysis of the stretches of the river Ganga by a Delhi-based environment NGO, Toxics Link, has revealed pollution by microplastics, defined as synthetic solid particles sized ranging from 1 micrometre to 5 millimetre (mm), which are insoluble in water. The Ganga flows across five States and has been at the centre of a massive multi-crore undertaking by the Union government, in the form of the National Mission for Clean Ganga, to rid it off contamination.
