Write short notes on

1.Plantation agriculture

SOLUTION

  1. Plantation agriculture is an extensive type of agriculture having large farm size on which one crop is cultivated. This is known as monoculture.
  2. Care has been taken to maintain the quality of the crop using scientific methods. This type of agriculture is modern as well as capital intensive agriculture.
  3. Since most of the work is done by human labour this type of agriculture is also referred to as labour intensive agriculture.
  4. The plantation crops once grown provides production for 10 to 15 years.
  5. Tea, coffee, rubber, cocoa, cashew nut, spices, etc., are the most important crops. For example, Rubber plantations in Kerala or tea plantations in Assam.
  6. Malaysia, Indonesia, Sri Lanka, India, Thailand, Vietnam, Caribbean islands are the important countries where plantation agriculture is practiced.

2.Physical factors and fishing

SOLUTION

Development of fishing requires specific physical factors. Therefore, it is developed on a commercial scale where physical factors are favourable for fishing. The following are the important physical factors, which can be responsible for the development of fishing.

  1. Broad continental shelf, with shallow water is favourable. For example, continental shelf along the eastern coastline of Japan is broad and water is shallow.
  2. Warm and cold ocean currents should meet near the coastline, so that plankton (favourite fish food) is available in plenty.
  3. Broken coast line which provides natural ports and harbours.
  4. Cold climate is favourable for natural preservation of fish.
  5. Since above all physical factors are present on the north-east coast of USA, north western coastline of Europe as well as in Japan, commercial fishing is well developed.

3.Lumbering on a commercial scale

SOLUTION

Commercial lumbering is well developed in coniferous forest region of Canada, North Western Europe and Soviet Union. The important factors responsible for the development of commercial lumbering in the above areas are as follows.

  1. In coniferous forest one species of trees are found over an extensive area.
  2. Coniferous trees are tall and away from each other so lumbering is easy.
  3. Wood is soft and durable. Coniferous forests provide good raw material for paper and pulp industry and furniture making industry.
  4. Due to good quality of wood (softwood) it has great demand in the world market.
  5. Cool and pleasant climate is favourable for labour to work throughout the year.

4.Hunting and loss of ecosystem

SOLUTION

Before the development of agriculture hunting was the important activity of man to obtain food. Many animal species were becoming extinct because of large scale hunting. Therefore, to protect the ecosystem, in many countries commercial hunting is banned. Presently, many laws are being passed to conserve and protect the animals and ecosystem. Yet, many tribal people such as Eskimos in Tundra region, Pygmies of Equatorial Selvas, Bushmen of Kalahari, Sentinels in Andaman etc., are still hunting.

Give geographical reasons:

1.Agriculture is done on a large scale in India.

SOLUTION

More than 46 percent of the total population of India is engaged in Agricultural Activities.

– In northern India, we have extensive fertile alluvial soil in Gangetic plains most suitable for the development of agriculture. In south peninsular India, there is very fertile black cotton soil suitable for a variety of crops. Along the coastal lines fertile soil is found in the deltas of river Krishna, Godavari, Mahanadi, Tapi, Narmada, etc. Many rivers like Ganga. Yamuna, Godavari, Tapi, Narmada and their thousands of tributaries and canals provide water for irrigation. The economic and social factors, including labour, market, capital, transportation facilities, storage facilities and government policies, etc., are all favourable for the development of agriculture.

2.Mining is developed in Chhota Nagpur plateau of India.

SOLUTION

The distribution of minerals is highly uneven in India. The geology of Chhota Nagpur region is very rich in minerals. There is concentration of minerals like iron-ore, manganese, mica, copper, limestone, and lead in Chhota Nagpur region. The government policy, capital investment in mining activities, technological development, availability of skilled labour, transport facilities, etc., are favourable for the development of mining activity in Chhota Nagpur region. Development of many industries related to minerals are located in this area, which gave boost to the development of mining activities.

3.Lumbering is developed on a large scale in Canada.

SOLUTION

Lumbering is one of the most important economic activity in the areas covered by coniferous forest in Canada. In Canada coniferous forest grow in large belt, since the climate is suitable for the growth of coniferous trees. In these forests only one species of trees grows in one area which is favourable for the lumbering. The development of lumbering depends upon the type of wood, climate, market and transport facilities. Commercial lumbering is developed in Canada because there is coniferous forest region, which provides soft wood, which is easy to cut, carry and durable. Cool climate of Canada, well developed transport facilities for the movement of logs, use of machinery for logging, large demand in local and international market for paper and pulp industries, limited development of other economic activities due to extreme cold climate are the other factors responsible for lumbering in Canada.

4.Extensive agriculture is a commercial type of agriculture.

SOLUTION

Extensive commercial agriculture was developed in temperate grassland region in Steppes, Prairies, Downs, Pampas and Veld grasslands. In these grassland areas population density is low and size of farms is very large from few hundred to thousand acres. There is extensive use of machinery from sowing to harvesting. Modern and scientific methods of agriculture are used, so production is large. The per hectare production is low whereas per capita production is high. Since population in those grasslands is very low and there is surplus production, therefore, large quantities of food grains are available for export, so this agriculture is known as commercial type of agriculture.

5.Lumbering is practiced more in coniferous region than in tropical region.

SOLUTION

Lumbering activity depends upon nature of wood – hard or soft, density of forest, number of species in the forest, transportation facilities, use of machinery and market. In coniferous forest region trees provide softwood, which is easy to cut and durable. In coniferous forest region one type of species are found in extensive area, so lumbering is easy. In coniferous forest region there is use of machinery for lumbering and transport facilities are also well developed. There is lot of demand for softwood in local and international market, hence commercial lumbering is more developed. On the other hand, in tropical region, density of trees is very high, different types trees grow in close proximity, so lumbering is difficult. In tropical region surface movement is difficult and transport facilities are not developed because of marshy land. In tropical region there is no local market since trees provide hardwood and therefore commercial lumbering is not developed.

6.Hunting has been banned.

SOLUTION

In the olden days hunting was the most important primitive activity of man to obtain food. Since agriculture was not developed, it was the only source of food for man. As a result, large number of animals were killed to such an extent, that some of the species of animal have become extinct or at the verge of extinction. In order to conserve and protect animals, hunting is banned all over the world.

  10.  

2.Write a note on Intensive Subsistence agriculture.

SOLUTION

  1. Intensive subsistence farming is practiced in densely populated countries like China, India. Japan, Sri Lanka and east Asian countries.
  2. Since there is large population and limited fertile agricultural land, there is small land holding.
  3. Farmers work intensively to get maximum yield from available small land.
  4. Rice is the dominant food crop produced in this region.
  5. Mostly manual labour and animals are used for all agricultural activities.
  6. Most of the production is consumed locally and hence no surplus is available for export.
  7. Yield per hectare is high but yield per capita is low.
  8.
