ROLE OF IT IN ENVIRONMENT AND HUMAN HEALTH
Information technology embodies processes, applications and equipment be which information can be accessed, created, communicated, organised, analysed or presented.
Information technology is becoming all pervasive and is causing and is causing a tremendous impact in the field of environment and human health. IT has dramatically reduced costs, increased speed and improved productivity in virtually all fields. It has opened up new challenges and opportunities.
The internet and the worldwideweb provide a vast quantum of current data that is readily accessible throughout the globe. It provides the most and relevant information in specific fields of knowledge. The information regarding the environment and its impact on human health that is available at the click of a button makes it possible to take corrective and preventive measures at the earliest.
IT in environmental education:
the role of information technology in environmental education and training has been well recognized and perceived as a tool that has the power to transform the country into a prosperous and pollution free healthy nation.
In the wake of recent developments in IT and communication technologies, a number of useful data banks have been established in various countries. These databases provides information about wildlife, conservation, forest cover, pollution control, clean technologies, remote sensing, coastal technology, biodiversity, renewable energy, mining, environmental management, etc. A vast amount of such information is available and this is also easily understood by everyone.
Remote sensing and geographical information system are the techniques of super imposing various thematic maps using digital data on a large number of related aspects. Many software have been developed for analysis and interpretation of the GIS data. These help in preparing zone wise atlases. Satellites also help in providing information about the monsoon, climate conditions etc.
Accurate forecasts of storms with proper prevention measures and disaster management techniques can greatly save life and property.
The ministry of environment and forest, government of India has created the Environmental Information System which is functioning in 25 centres all over our country. ENVIS is a body that generates network databases in the area of pollution control, remote sensing, coastal technology, biodiversity, renewable energy, mining, environmental management, etc. The body is also involved in developing Tsunami warning system in the Indian Ocean.
IT and human health
In recent years, innovations where IT and the life sciences converge have created vast qualities of data.
Telemedicine is an important IT application in the field of human health. Through this technology a doctor in the US can diagnose , treat and even operate a patient in India. This technology is particularly useful in heart surgery and results in cost effective treatment.
IT helps in broadcasting the preventive measures to be taken against communicable diseases and diseases like Acquired Immuno Deficiency Syndrome (AIDS). The Indian Council for Medical Research (ICMR) has developed a database for diseases like AIDS, malaria etc.
The development for automated DNA sequencing and other innovative methods have reduced the costs and time needed to discover the genetic make up of various organisms. Additionally, innovations such as high through put screening and micro arrays are enabling studies of gene and protein functions ( that is genomics and proteomics)
Summing up, the rapid growth in Information Technology and the highly qualified man power in India are bound to have a positive impact on the earth’s environment and human health among others.
With the help of Information Technology, we are able to note down the on-going changes or we can predict things that are to happen in near future. It has also helped us in many ways in knowing the true facts. One of that is as follows.
Improving quality of life without conventional economic growth in Kerala
In India, Kerala is a unique state that has a low birth rate and a high literacy rate. The following case study with the help of information technology explains how the literacy rate of the state has grown.
The state of Kerala in south west India has shown how the quality of life can be improved without emphasis on economic growth. Even though it is one of the world’s least economically developed areas, with a per capita income of less than $200 ( compared to $350 for India and $ 810 for all the developing countries), in terms of life, it has some of the highest scores among developing countries.
Kerala leads India in the quality of its roads, schools, hospitals, public housing, immunisation programmes and the sanitation and nutrition programmes for pregnant women and infants. Almost 94% of Kerala’s citizens can read and write, compared with fewer than 50% for the rest of India. Life expectancy in Kerala is 68 years while for India as a whole it is 57 years. The infant mortality rate is 27 per 1000 births, compared to 63 for the LDCs and 27 for India. The total fertility rate is 2.3 in Kerala, compared with 3.6 for India.
All the people of Kerala have access to free or inexpensive medical care and all households have ration cards that allow them to buy rice and certain basic commodities at subsided prices. Since 1960, a land reform programme had benefited more than 3 million tenants and landless poor.
