Agrarian Structure of Indian society

Agrarian Structure of Indian society through the lenses of land reforms till date

History of agricultural set up in India

Indian agriculture began in India in 9000 BCE.It is one of the main occupation in India at that time and even today it one of the main source of earning livelihood.

Vedic Period 
The period also for the first time saw the domestication of animal elephant.Economy in the Rig vedic period was sustained by agriculture and pastoralism.Agriculture dominated the economic activity,its operations became complex with use of iron implements like black metal. Crops like wheat,rice,barley were cultivated,

Later Vedic period
During this period wide range of cereals, fruits, vegetables were cultivated. Animal husbandry was also prevalent. Agriculture became much developed than the rigvedic period. Rice, wheat and barley was mainly cultivated. Cotton cultivation was in vogue. Various domesticated animals was used in ploughing.

Indus Valley Civilisation
During this time though agriculture was important for their livelihood but to some extent people were engaged in various other types of trade in order to earn their livelihood. Indus people used to keep cattles, goats, pigs, sheeps for food. Farmers grew fruits such as dates, grapes, melons and also wheat and peas.

Middle Ages-Early Modern Era (1200-1757AD)
The Tamil people cultivated a wide range of crops such as rice, sugarcane, millets, black pepper, various grains, coconuts, beans, cotton, plantain, tamarind and sandalwood.Jack fruit, coconut, palm, areca and plantain trees were also known.  Systematic ploughing, manuring, weeding, irrigation and crop protection was practiced for sustained agriculture.
Portugese introduced the cultivation of tobacco. The Malabār Coast was the home of spices, especially black pepper, that had stimulated the first European adventures in the East. Coffee had been imported from Abyssinia and became a popular beverage in aristocratic circles by the end of the century. Tea, which was to become the common man's drink and a major export, was yet undiscovered, though it was growing wild in the hills of Assam.
Land management was particularly strong during the regime of Akbar the Great (reign: 1556-1605), under whom scholar-bureaucrat Todarmal formulated and implemented elaborated methods for agricultural management on a rational basis. Indian crops—such as cotton, sugar, and citric fruits—spread visibly throughout North AfricaIslamic Spain, and the Middle East.

Colonial British Era – Republic of India (1757-1947)
Few Indian commercial crops like opium, cotton, indigo and rice made it to the global market under British raj in India. Due to increase in the production of agricultural crops were seen in the 19th century, canals were built.
After independence India focused on agriculture in order to become self sufficient in providing food to its people.  Special programs were undertaken to increase the supply of food supply. A milestone in Indian history in order to improve the food production was the introduction of the Green Revolution in the year 1960. This helped to make India a self sufficient country with increasing GDP growth. Even India’s export and import increased through the agriculture.

Later many developments took place in order to strengthen the sector of agriculture like constituting NABARD,Council of agricultural research, National Dairy Development Board, etc.

Land Reforms in India

Introduction
Land Reforms in India is done mainly help the poor farmers and land holders to get rid of various difficulties like abolishing land tenure system,ceiling on land holding, distribution of surplus land, consolidation of holdings, compilation of land records.The main aim for introducing land reforms in India in order to save the poor and landless poors from being exploited in land relations, empowerment of women to ensure greater access to land and abolishing gender bias in land legislation.

What’s the need of land reforms:
The need of land reforms in India can be felt if we quickly take a look at the history of land reforms which took place after independence in India-
1.Government came up with the land reforms in the first five year plan started  in 1951.
2. In the second five year plan the abolition of intermediaries took place in order to give protection to the tenants.
3. The second five year plan categorically ruled out the procedure of land ceiling. The plan proposed that the ceiling of the holding should be fixed at about three family holdings.
4. Abolition of Zamindars and other intermediaries (jagirdars, inamdars, malgujars, etc) between the state and the cultivator.
5. A high powered committee in 1948 with J.L.Nehru as its Chairman recommended that all intermediaries should be replaced by non-profit making agencies like cooperatives..

National Land Reforms Policy

This policy focuses on those aspects of land reforms which if implemented in true letter and spirit will have the potential to tilt the balance in favour of the landless and poor.
Recognising the need for land among the poorer sections of the society, many S tate Governments had come up with land distribution programmes to facilitate land ownership for the poor.
In addition to the govt. lands, other categories of land like the ceiling surplus lands, bhoodan lands etc.were also distributed to the landless poor for cultivation purposes.
In order to provide homestead land, minimum agricultural land, and shelter to every family, it is essential that a land pool is created.
Evict ineligible encroachers of government lands, ceiling surplus and bhoodan lands and distributeto the landless poor.
Every state should revise its ceiling limits, if the existing limit is more than 5-10 acres in the case of irrigated land and 10-15 acres for non- irrigated land.
States shall adopt single window system for re- distribution of ceiling surplus land within a specified time frame.
There is an urgent need to re- visit the land ceiling limits in different categories. Excluding the achievements of some States like West Bengal, Kerala, and J& k.

Impact Of Land Reforms

End of feudalism, feudal land owning classes.
Updation of land records.
The land reforms in India have led to emergence of a class of modern entrepreneurs of farmers.
It has reduced the exploitation of tenants and income of the small farmers.

Indian Space Programme



Indian Space Programme

The Indian Space Programme has a number of activities but the ones that are of some interest to geographers are those of the ones discussed below. India Space Research Organisation (ISRO) has an ambitious programme of remote sensing applications, some of which are reflected here in the chapter.

Regional Remote Sensing Services Centre’s (RRSSCs)

Recognizing the need and importance of natural resources management in the country, Government of India has set-up the National Natural Resources Management System (NNRMS).

NNRMS is an integrated approach for management of natural resources, optimally utilizing the advantages of conventional systems and the information derived through remote sensing. Department of Space (DOS) is the nodal department in Government of India for evolution, establishment of NNRMS and all remote sensing related activities. With a view to have optimum use of space technology for national development it was felt necessary to create facilities for analysing remote sensing data to derive planning related inputs on natural resources of our country. Towards this, DOS has established five Regional Remote Sensing Service Centres (RRSSCs) in the country for speedy operationalization of remote sensing as an integral component of natural resources inventory, monitoring and management. RRSSCs enable the use of remote sensing technology at a reasonable cost to derive necessary information on various aspects related to natural resources. These centres are located at Jodhpur (Western Region), Dehradun (Northern Region), Kharagpur (Eastern Region), Nagpur (Central Region) and Bangalore (Southern Region) function under RRSSC, Central Management Office, ISRO Headquarters, Antariksh Bhawan, Bangalore.

Objectives and Functions

Integrated Mission for Sustainable Development (IMSD)

Under IMSD, locale-specific action plans for sustainable development of land and water resources are generated on watershed basis, integrating thematic information generated using satellite data with collateral/conventional information and socioeconomic inputs. The action plans are basically recommendations towards improved soil and water conservation for ensuring enhanced productivity, while maintaining ecological/ environmental integrity of the area/region. The action plans, to illustrate, address identification of sites/areas for surface water harvesting, groundwater recharge, soil conservation measures – through check dams, vegetation bunding; sites/recommendations for improved/ diversified farming systems with fodder, fuel wood plantations, agroforestry, and agro-horticulture. These action plans are generated by the joint involvement with the respective Governments departments, State Remote Sensing Centres, universities, private entrepreneurs and NGOs.

National (Natural) Resources Information System (NRIS)

NRIS forms the core information system for the NNRMS and is oriented to aid decision-makers at national, regional, state and district levels to plan various developmental activities in a scientific, systematic, timely and optimum manner. The NRIS provides spatial data-bases of spatial (thematic) and non-spatial data with GIS solutions for decision making. It is organised in interlinked/networked hierarchy so as to cater to free flow of resources information. This venture has set a new trend amongst State-level missionary to have organised natural resources,databases at district level.

Bio-Diversity Characterisation

A major project has been taken up for Biodiversity Characterisation at Landscape Level to prepare Biological zone maps and establishment of disturbance gradient for important bio-diversity rich areas of the country using remote sensing and GIS. RRSSCs are actively involved in the project both in database creation and providing software solutions under image processing and GIS domain. The project is aimed at prioritising areas for bio-prospecting and conservation.

Agro-Climatic Planning and Information Bank (APIB)

A pilot project on APIB in Karnataka State has been on-going for consolidating the large amount of statistical and spatial information generated by various organisations and to create a single-window knowledge base for agricultural development. The purpose is to provide area specific information on all aspects of farm management that can be implemented by the farmer himself. This bank is not only an information or data bank but also a facilitator by providing the users with tools required for preparing developmental plans.

Rajiv Gandhi National Drinking Water Mission

This is a national mission with an objective of creating scientific database for ground water using remote sensing technology. RRSSCs are involved in the generation of precision products and ground water prospect maps at 1:50,000 scale for the states of Kerala, Karnataka, Andhra Pradesh, Madhya Pradesh and Rajasthan.

Crop Acreage and Production Estimation

This is a important national mission wherein remote sensing techniques are used in providing pre-harvest estimates on crop acreage for major crops in various states in the country. RRSSCs have been actively involved with Space Application Centre, Ahmedabad in providing software solutions through a package “CAPEWORKS”. The package is operationally being used in all ISRO work centres and various State remote sensing centres regularly during the cropping seasons to derive the necessary information related to crops acreage.

Watershed Related Studies

RRSSCs are actively involved in watershed development related studies in the country. IMSD project has paved the way for scientific approach for planning and implementation of certain action plans to improve the land productivity and water resources in a given watershed.
RRSSCs are actively involved at national level in monitoring/evaluation of watersheds treated under NWDPRA scheme using multi-temporal remote sensing data. Methodology for operationally executing such a project was developed within RRSSCs on a pilot mode and the same has been operationally utilised for the project.

Disaster Management System – Flood Damage Assessment

RRSSC Kharagpur, one of the regional centres, is well located to provide quick information related to flood and cyclone related disasters. The centre is actively involved in generating such information using remote sensing and GIS techniques. RRSSCs are actively involved in creating digital databases for the flood-prone region of Assam and developing information system for decision making for effective management of disaster. The methodology can be replicated for other flood affected areas in due course of time.

Study of potential and actual area under sericulture through Remote Sensing

Remote sensing techniques have been proved to be useful in studies related to sericulture which basically refers to identification of mulberry growing areas. The technique has proved to be very successful and cost effective in the country. RRSSCs are currently involved in a national mission on the project.

Image Processing Solutions

RRSSCs have expertise to deal with variety of image processing solutions. State of the art packages are available for processing remotely sensed data. Many applications have been provided with turn-key solutions by customising the application for smooth implementation.

Floods in India

India is prone to floods, just as any other country in the world. What is worse however is that when rivers in one part are in spate, the land in other parts could be parched. Floods and droughts always occur at one and the same time, making life difficult for the people on both the counts. Floods are a common, everyday occurrence and in floodplains more so than anywhere. The India Meteorology Department uses a simple classification of floods, and defines that rainfall in excess of 75 per cent causes very severe floods, 50 per cent severe floods and 25 per cent moderate floods. The State of Assam, for example, located in the north-east region of India, has become a multi-disaster prone area. Due to deforestation in the upper catchment areas of the rivers and the lack of proper maintenance of dams and protective embankments, the region is becoming more and more vulnerable to flooding. In the last two years, the monsoon floods have become a nightmare to thousands of resource-poor people living at the side of the mighty Brahmaputra river. Every year, the river is becoming wider and wider, consuming vast areas of fertile land and human habitations. With the advent of the monsoon in June 2004, for example, there was heavy rain in the entire region, including Bhutan. When the Kuriso Dam in Bhutan was in danger of overflowing in early July the authorities released unexpectedly large amounts of water, which caused an increase in the level of the Brahmaputra River. In early July, it again started to rain heavily in this area and water levels in the rivers started rising again. From July 10, 2004 onwards, the rivers started overflowing their banks and more and more areas became inundated resulting in a major flood. At several places, breaches developed in the embankments and torrents of water swept through villages and washed away a large number of houses. Twenty three districts have been severely affected by the floods. Goalpara and Dhubri districts are among the worst affected. Bongaigaon, is also badly affected.

Choosing Flood Hazard Categories:

It is necessary to divide the floodplain into flood hazard categories that reflect the flood behavior across the floodplain. CSIRO (2000) refers to the degree of flood hazard as being a function of:


  • ·         the size (magnitude) of flooding;
  • ·         depth and velocity (speed of flowing water);
  • ·         rate of floodwater rise;
  • ·         duration of flooding;
  • ·         evacuation problems;
  • ·         effective flood access;
  • ·         size of population at risk;
  • ·         land use;
  • ·         flood awareness/readiness;
  • ·         Effective flood warning time.

There are four degrees of flood hazard: low, medium, high and extreme. The categorisation of the floodplain is largely qualitative using the above factors. For example, medium hazard is where adults could wade safely, but children and elderly may have difficulty, evacuation is possible by a sedan, there is ample time for flood warning and evacuation and evacuation routes remain trafficable for at least twice as long for the required evacuation time. A key factor in the case of evacuation from an area is the water depth and the velocity along the evacuation route; that is, the stability of pedestrians wading through flood waters or vehicles driving along flooded roads. There are some estimation procedures available for stability estimation, but further research is required across a broader range of conditions.

Recommended Approach

In considering the application of flood related issues to the specific flood characteristics of the lower Johnstone River floodplain, it is noted that:


  • ·         duration of flooding is universally long (in the order of days) across the floodplain;
  • ·         warning times can be short (~ 6 hrs);
  • ·         rates of floodwater rise are reasonably fast; and
  • ·         Flood-awareness is generally high and does not vary significantly across the floodplain.

The four parameters are not significantly variable across the floodplain to warrant specific treatment and are therefore not used to define variations in the flood hazard, but should be included in development control measures. The flood hazard is therefore defined on the remaining, varying characteristics of:


  • ·         the size of the flood;
  • ·         depth and velocity of floodwaters; and
  • ·         evacuation and access.
