  1. Primitive subsistence farming
    • Migratory subsistence farming
    • Sedentary subsistence farming
  2. Intensive farming
  3. Commercial farming
  4. Mixed farming
  5. Plantation farming
  6. Dry farming
  7. Humid farming
  8. Irrigation farming

1. Primitive Subsistence Farming : The production of crops for the purpose of domestic consumption and not for commercial use is called “Primitive subsistence farming”. Farmers -used primitive methods of cultivation. This types of farming is widely practiced in hilly regions like North-easterns states, Odisha and Madhya Pradesh. Primitive subsistence farming can be classified into two types. They are –

(i) Migratory subsistances farming and (ii) Sedentary subsistence farming.

(a) Migratory subsistances farming : It is a primitive method of farming, practised by tribals in the tropical rainy forests. Under this system formers clear patches of forest by cutting and burning the bushes and trees and cultivate land. Later people migrate to another parts of the forest. Along with cultivation of crops, hunting, fishing and collection of forest resource etc are done by the people.

This type of farming is called by different local names-eg- ‘ Jhumming’ in North Eastern regions(Assam), ‘Koman’ in Odisha, ‘Ponam’ in Kerala, and ‘Podu’ in Andhra Pradesh. Yams, Peanuts, beans, bananas, upland rice, buck wheat, maize, millets and sometime vegetables are grown under this farming. This farming is practiced in Assam, Meghalay, Nagaland, Manipur, Tripura, Mizoram, Arunachal Pradesh, parts of Madhya Pradesh, Odisha and Andhra Pradesh.

(b) Sedentary subsistence farming : This is an ancient form of cultivation and practiced by the people living permanetly. Here there is physical factors are favourable for cultivation, of land. The farm lands are not abandoned. They are cultivated through of the year and farmer lived near the land. Hence, this system is called “Sedentary subsistence farming”. Under this system, implements used and the mehtods Of cultivation are primitive. The surplus agricultural produce are sold to neighbouring people or sold in the market.

Sedentary subsistence farming also includes the rearing of animals for milk, meat, woo! and hides.

2. Intensive farming : It is found in the areas of dense population and land holdings are small. in this type of farming land in intentively used and 2-3 harvests are obtained in year. It is known as “Intensive farming”.

It is labour and capital Intensive farming. Large amount of labour and capital is used on a small land holding, to get maximum production of crops. The available small piece of land is ised for cultivation with irrigation facilities throughout the year. In this system, farmers try to raise two or more crops, with careful tilling of the soil. Intensive agriculture is characterized by high yields per unit area and farmers try to get the maximum production from small land holdings. It is common in the fertile and irrigated parts of the country. In this type, agricultural operations are carried on by manual labour and draught animals. Rice is the main crop of Intensive farming in India.

3. Commercial farming : Agricultural crops are produced on a large scale.for the purpose of sale and not for domestic consumption, is called ‘Commercial farming’. This type of farming is generally practised in the large areas of sparse population with good transportation facilities. On large scale farms, using small amount of labour, large scale use of machinery, cash crops are growth for scale.

It requires large amount of labour and capital. Manual labour and skilled labour is important. Under this system crops are grown mainly for export. The important plantation crops of India are Tea, Coffee and rubber.

6. Dry farming : The farming system practised in areas which receive scanty rainfall (i.e, less that 50 cms) and irrigation facilities are very limited or absent is called ‘Dry farming’. This type of farming is practiced in Deccan plateau of south India, Western Rajasthan and other arid and semiarid regions. Famines and droughts are common in these regions. Crops are growing with low yield. Only quick maturing and drought resistant crops are cultivated. Jowar, bajra, ragi, oilseeds are the important dry farming crops.

7. Humid farming: Cultivation of crops, where the areas receiveing sufficient rainfall without the help of irrigation is known as Wet farming or Humid farming. If the rainfall is sufficient i.e. 100 to 150cms throughout the year, double or multiple cropping is practiced in that area. Rice, sugarcane, Jute, tea, coffee, rubber etc, are grown. Sufficient rainfall helps to obtain higher yields and better quality of crops.

8. Irrigation farming: Cultivation of crops with the help of Irrigation is called ‘Irrigation farming’. This type of farming is very essential to India, because monsoon rainfall is seasonal, uncertain and insufficient. The largest area of cultivated land is under irrigation in India. This type of farming is highly concentrated in Uttar Pradesh, Punjab, Haryana, Bihar, Odisha, West Bengal, Andhra Pradesh, Tamil Nadu and Karnataka, and also practiced in many other states of the country.

  • By Personal observations: It refers to the collection of data or information by individual or group of individuals, through direct observations in the field.
  • By Questionnaire : The most common method used in surverys is the Questionnaire. In this method, simple questions and their possible answers are written on a plain paper, and the respondents have to tick mark the possible answers from given choices.
  • Others methods :
    • Telephone interview : In this method, the researcher/interviewer can collect the information over the telephone.
    • Measuring properties: In this method, the data about properties of soil nd water collected directly from the field by measuring their characteristics using soil and water quality kit.

Question 38.
Explain the segment of GPS
There are three segments of GPS:

1. The space segments : The satellites of GPS are launched and positioned at an altitude of approximately 20200 km which is almost more than three times of the earth’s radius. The space segment consists of a constellation of 24 functioning GPs satellites located in 6 orbital plane with 4 satellites in each orbital plane. The time for the satellite to complete one revolution around the earth is 11 hrs and 58 minutes.

2. The control segment : The control segment consists of facilities necessary for satellites especially healthy monitoring, telemetry, tracking command and control clock error computation of satellites. There are 5 GPS stations spread over the earths surface they are-

  • Hawaii
  • Colorado spring
  • Ascension island
  • Diego Garcia
  • Kwajalein.

3. The user segment : it is a total user and supplier community, both civilian and military. The user segment consists of all earth – based GPS receivers. Receivers very greatly in size and complexity, through the basic design in rather simple. The space and control segments are largely transparent to the operations of navigation functions.

  • Navigation : In navigation, by using GPS can save countless hours in the field. Any feature, even if it is under water, can be located upto one hundred meters simply by scaling coordinates from a map, entermg way points & going directly to site.
  • Remote sensing and GIS : GPS positioning can be intergrated into remote – sensing methods such, as Photogrammetry and aerial scanning, magnetometry, and video technology using DGPs techniques.
  • Surveying/Mapping : The high precision ofGPS carries phase measurements, together with appropriate adjustment algorithum, provides an adequate tool for a variety of tasks for surveying and mapping.
  • Geodescy : Geodetic mapping and other control surveys can be carried out effectively using high grade GPs equipment.
  • Military : The GPs was Primarily develped for real time military positioning. Military applications include airbone, marine and land navigation.

Question 39.
Write the importance of remote sensing.
Remote sensing is the science and art of obtaining information about an object, area or phenomenon through the analysis of data aquired by a device that is not in contact with it.

This is done by sensing and recording reflected or emitted energy and processing, analyzing and applying that information.

In much remote sensing. the process involves an- interaction between incident radiation and the targets of interest. This device can be a camera or a bank of sensors operated from an airplane or a satellite. Though satellite we can collect date related agriculture, forest, urban land use, watcr, natural calamities etc the satellite data is based for mapping, monitoring, studyIng the various phenomena related to earth’s surface.
