Classification of Industries The general difference between one industry and other measured according to the nature of the product, number of employees, value of the capital involved, quality of employees, wage rate, value addition of the product and nature of raw materials. Numerous classifications are available, each quite different from another. One emphasized on raw materials, another on product and even on transport cost. The Weberian model introduced an industrial classification based on raw materials. According to his model, industries may be sub-divided into following categories – I. The industries based on ubiquitous raw material: This type of industries use raw materials available everywhere, e.g. air, water, soil, etc. II. The industries based on localized raw material: These industries use raw materials, confined within some selected region, e.g. coal, petroleum, iron ore, etc. These industries are again sub-divided, according to weight loss ratio or material

Applications Natural resource management is a broad field covering many different application areas as diverse as monitoring fish stocks to effects of natural disasters (hazard assessment). Remote sensing can be used for applications in several different areas, including: q        Geology and Mineral exploration q        Hazard assessment q        Oceanography q        Agriculture and forestry q        Land degradation q        Environmental monitoring,… (Each sensor was designed with a specific purpose. With optical sensors, the design focuses on the spectral bands to be collected. With radar imaging, the incidence angle and microwave band used plays an important role in defining which applications the sensor is best suited for.) Each application itself has specific demands, for spectral resolution, spatial resolution, and temporal resolution. For a brief, spectral resolution refers to the width or range of each spectral band being recorded. As an e

CLASSIFICATION OF RESOURCES             Resources may be looked upon from several angles, and, hence, may be classified in different ways which are : (a) presence or absence of inanimate matters, (b) exhaustible or inexhaustible, (c) ownership and (d) distribution. (a) Inanimate resources exist in solid, liquid or gaseous forms. Water, fuel, minerals, metallic are some of the examples. Animate resources are comprised of those derived out of man, animal, fishes etc. (b) Resources may be classified as exhaustible and inexhaustible. Exhaustible or fund resources refer to those which diminish in the process of utilisation, for example, coal, iron ore, petroleum and she like. Again some natural things are self-renewable and their supplies continue perennially. The climatic seasons or the periodic rainfall of a region will unmistakably rotate for year after year. The velocity of flowing water which yields hydel power is permanent. Forests, if judiciously exploited, are also a f

IN HOT REGIONS - THE BUSHMEN       Their real name is known as the San, they are hunters and gatherers. At present they are found in Botswana, Namibia and Angola. The San population is estimated at about 50,000 (in 2001). They group into small bands of 30 to 100 and they camp or stay only a few weeks at one place and do hunting and gathering over an area of 600 sq.km.             TERRITORY : - The Bushmen are mainly confined in the barren inhospitable environment of the Kalahari Desert and the adjacent sub-topical grasslands of Southwest Africa. The desert has 102-254 mm or 4-10 inches of rainfall in a year. Towards north of the desert region situated the famous Etosha National Park.             The habitat of Bushmen, contain forests, grasslands and thorny bushes and are renowned or famous in numerous herbivorous and carnivorous animals.             CLIMATE :-They live in a plateau, about 2000 meters above sea level. Climate is subtropical, gets rainfall in summer

Climate of Mizoram Despite it tropical location Mizoram enjoys a moderate climate. This mainly due to its fairly high elevation. It is neither very hot nor too cold throughout the year. The region falls under the direct influence of the south-west monsoon. As such the region receives an adequate amount of rainfall. The climate is humid tropical, characterised by short winter, long summer with heavy rainfall. Temperature : Since there are no proper observatory stations in Mizoram, it is not possible to give a comprehensive information about the temperature conditions of the region. The analysis is based mainly on the observations and data generated by the author with meagre temperature records available on the region. The salient thermo-characteristics of Mizoram is that temperature do not fluctuate much throughout the year, excepting in the low-lying valley sites. However, it is observed that there has been a steady increase in the annual temperature, at par with the glo

MIZORAM Location and Extent Mizoram lies between 21 0 56’N – 24 0 31’N latitudes and 92 0 16’E – 93 0 26’E longitudes. Sandwiched between Bangladesh and Myanmar, its location is of strategic significance geographically and politically, and shares a total common international boundary of about 585 kilometres with these two countries. In terms of the size, it may not be so significant as its total area constitutes only 0.64 per cent of the total area of India.             The tropic of cancer, i.e., 23 o 30’N latitude cuts across the region in Aizawl district at the southern periphery of Aizawl traversing places like Champhai, Chhawrtui, Darlung and Phuldungsei etc. This imaginary line divides the region into two almost equal parts. Mizoram is bounded on the north by Cachar district of Assam and the state or Manipur; on the east and south by Chin Hills of Myanmar; on the west by Chitagong Hill tracts of Bangladesh and the state of Tripura.             Mizoram has a tot
