National Air Quality Monitoring Programme (NAMP)
Central Pollution Control Board (CPCB) with the help of concerned State Pollution Control Boards (SPCBs) and Pollution Control Committees (PCCs) is monitoring the ambient air quality in the country at 346 stations covering 130 cities and towns. This is done under the National Air Quality Monitoring Programme (NAMP).

Under this programme, Central Government provides funds through CPCB for National Air Monitoring   Programme to various SPCBs and PCCs.

The objectives of the NAMP are to
·         determine the status and trends of ambient air quality; to ascertain whether the prescribed ambient air quality standards are violated; to identify Non-attainment Cities
·         to assess health hazards and damage to materials;
·         It also provides background air quality data needed for industrial siting and towns planning.
·         to control and regulate pollution from industries and other source to meet the air quality standards
·         to continue the ongoing process of producing periodic evaluation of air pollution situation in urban and industrial areas of the country;
·         to obtain the knowledge and understanding necessary for developing preventive and corrective measures and
·         to understand the natural cleansing processes undergoing in the environment through pollution dilution, dispersion, wind based movement, dry deposition, precipitation and chemical transformation of pollutants generated.

Under the NAMP, four air-pollutants viz., Sulphur Dioxide (SO2), Oxides of Nitrogen as NO2 (i.e. Nitrogen Dioxide), Suspended Particulate Material (SPM 2.5) and Respirable Suspended Particulate Matter (RSPM/PM10) have been identified for regular monitoring at all the locations.

The monitoring of meteorological parameters such as wind speed and wind direction, relative humidity (RH) and temperature were also integrated with the monitoring of air quality.
The monitoring of pollutants is carried out for 24 hours (4-hourly sampling for gaseous pollutants and 8-hourly sampling for particulate matter) with a frequency of twice a week, to have one hundred and four (104) observations in a year.

The monitoring is being carried out with the help of Central Pollution Control Board; State Pollution Control Boards; Pollution Control Committees; National Environmental Engineering Research Institute (NEERI), Nagpur. CPCB co-ordinates with these agencies to ensure the uniformity, consistency of air quality data and provides technical and financial support to them for operating the monitoring stations. N.A.M.P. is being operated through various monitoring agencies.


It is pertinent to mention that these data be treated as indicative rather than absolute.

Alliance For Zero Extinction (AZEs) Formed in 2000 and launched globally in 2005, the Alliance for Zero Extinction (AZE)  comprises 100  non-governmental biodiversity conservation organizations  working to  prevent species  extinctions  by identifying and safeguarding sites where species evaluated to be  Endangered  or  Critically Endangered  under  International Union for Conservation of Nature (IUCN)  criteria  only exist at one location  on earth.   AZE members work to rebuild populations of endangered and critically endangered species through efforts to eliminate human threats such as commercial exploitation, disease and the introduction of invasive species. AZE provides expertise on  biodiversity  goals for the  Convention on Biological Diversity (CBD)   and assists party nations in integrating protection of AZE sites and species into  National Biodiversity Strat...

Every Government talks about raising the level of education..It has a special mention in our Constitution enshrined in article 21A, 30 etc…but today I would like to share a “experience of school” of one child…he was not good in studies but anyhow he got admission in one of the good school of that time…but  what he faced on the first day was shocking for him…when he entered the class, nobody was ready to offer him a seat…atlast, he got a seat of the last bench sittin g alone the whole day…but he was curious to know why even the single student didn’t offered him a seat…anyways he moved on and forgot those things…but as he was not a meritorious student, he faced another discrimination…DISCRIMINATION from the group of brilliant students of that class…whenever he asked for any help regarding studies, not a single student among them tried to lend a helping hand, friendship to dur ki baat thi…they only do friendship with those who are good at studies…but that child moved on and that chi...

Key Biodiversity Areas Key Biodiversity Areas (KBAs) is an umbrella term commonly used to include areas that contribute to the  global persistence of biodiversity , including vital habitat for threatened  plant and animal  species in  terrestrial, freshwater and marine ecosystems.  Globally KBAs are designated based on 11 criteria defined under  five broad categories  of  1.      Threatened biodiversity;  2.      Geographically restricted biodiversity;  3.      Ecological integrity;  4.      Biological processes; and,  5.      Irreplaceability.  KBAs are  identified nationally  using globally standardised criteria and thresholds. KBAs is an important approach to address biodiversity conservation at the  site scale  i.e. at the level of individual protected areas, concessions and land...
