Abstract

The anomalies observed in the reverine systems have been demonstrated to be the potential tool in deciphering the tectonically active zones. Such various drainage anomalies viz: radial drainages, anomalous compressed meanders, eyed drainage and the youthful floodplains observed in Annamali – Palani - Varushanad hill ranges of the Western Ghats of Tamil Nadu show that the N-S and NE-SW trending faults are tectonically active in the recent years.

Much has been talked about the mighty river systems and their migratory histories, since Purana and Vedic times. In Mahabharata the places where the Lord Krishna is said to have played with Gopis in the banks of River Yamuna are now forming flat lands many kilometers away from the present day Yamuna. In the same way, there is a mention in ancient literature about the ‘Indo-Brahm’ river which was originated from the Himalayas and flown through Brahmaputra valley, Indo-Gangetic plains, Rajasthan desert and met the Arabian Sea in Rann of Kutch. Such a mighty river is said to have fragmented into Brahmaputra, Ganges and the Indus rivers due to Tectonic activity in Himalayan regions. Similarly there are many evidences in the Tamil literature. For example in ‘Kalingathuparani’ it is mentioned that the river ‘Palar’ was flowing north of Kanchipuram but the same river is now flowing south of it.

All these facts show that the rivers have the tendency to frequently change their courses. The advent of modern Remote Sensing Technology has opened up new vistas in studying such migratory rhythms of the rivers, as such old and buried rivers exhibit spectacular ribbon like, linear, curvilinear and contorted features with typical darker tone in black and white images and reddish tone in false color composites (FCC) and other color coded images.

Abstract

The Remote Sensing and the followed up field based investigations show that the Tamil Nadu coast, India, is facing series of geoenvironmental problems due to tectonic movements and morphodynamic processes. Such problems pose a challenge to the engineering geologists. The paper discusses such challenging engineering geological problems and plausible remedial measures.

Introduction

Food and nutritional security continues to be the main plank of India’s food policy despite its tremendous achievements on food production front during the last three decades. The Green Revolution helped India to overcome chronic food scarcity and made it self sufficient in food production. The per capita availability of cereals increased from 360 gms/day in 1966 to 422.4 gms/day in 2004. On the other hand, availability of pulses, the main source of protein for over- whelming vegetarian population of India, declined from 48 gms/day to 38 gms/day, which is attributed largely to diversion of land from pulses to cereals crops (Gopalan et al, 2004). The extra income generated due to Green Revolution has increased the access of rural population to a wide variety of foods, like milk, meat, eggs, fish, fruits and vegetables, which perhaps could offset the protein deficiency due to decline in per capita availability of pulses, therefore, resulting in the increase in per capita consumption of protein in rural areas. The trends in cereal consumption indicate that per capita cereal consumption has been declining in most of the states. This trend is more prominent in agriculturally developed states, like Punjab and Haryana. In these states, production and per capita consumption of milk have increased substantially.

The dietary pattern in India remains cereal based and the expenditure shares of foods of animal origin (meat, eggs and fish) and fruits, which are rich in nutrients, are trivial. More than 22 per cent of the population stays below poverty line and generally suffers from various nutritional disorders due to lower purchasing power. The nutrient rich foods like milk, meat eggs, fruits, etc. are highly responsive to income changes. Besides, choice of food and consequently the level of nutrient intake is also influenced by the other economic, social, cultural and climatic factors. Spurt in income growth and increasing consumerism in rural areas in recent years has heightened the need for understanding the food consumption pattern. Using the farm level data from three regions of Maharashtra this paper attempts to examine the pattern of consumption of nutrients by cultivators and sources of supply of different nutrients.

Introduction

India is well-known around the world for its rapid economic growth rates over the last fifteen years or so, fuelled in part by the spectacular growth in its export- oriented software and ICT-based services sector. Many other countries look to India as a model for global outsourcing and try to imitate elements of this in their own strategies (Carmel 2003; Heeks and Nicholson 2004). Success at a particular period of time does not, of course, guarantee its continuation and commentators have expressed concerns such as rising wage rates and skills shortages of ICT professionals (CACM 2007), and increasing competition from countries such as China (Negroponte 2003). It is likely, however, that India will remain a major player in the ICT industry for years to come and thus its global image as an ICT success story will continue. Viewed from a broader development perspective, things are not so simple. The new wealth that has arisen in India from the ICT boom benefits the relatively wealthy and educated in the first instance (Kambhampati 2002). Will this trickle down to the poor and uneducated? Statistics paint a mixed picture of the current situation. On the one hand, India is now the world’s fourth largest economy in purchasing power parity terms, and has enjoyed high growth rates for over a decade rising to an average of over 8% per annum in the period 2004-7 (World Bank 2007).

On the other hand, India was ranked as 128th out of 177 countries on the human development index 2005 (UNDP 2005) which is a composite index based on life expectancy, literacy and education levels, and economic standard of living. Shocking statistics include the percentage of malnourished children under 5 being 46%, the adult female literacy rate as only 48%, and the percentage of the rural population using adequate sanitary services as 18% (World Bank 2007, UNICEF 2004). A major development issue, therefore, is whether India can seriously address the needs of all of its people, including the vast numbers of poor and uneducated in the rural areas and the urban slums. A related sub-question is whether, and to what extent, can ICTs be used to provide development benefits to all Indian citizens. There are increasing attempts to use technology in this way through projects such as e-government services and telecentres in poor areas.

Introduction

Knowledge and Knowledge management are concepts, which are debated extensively by managers, analyst and academicians. When we refer to knowledge, most of us mainly tend to think of codified and documented knowledge like patents, databases, manuals, white papers etc. knowledge is intuitive, contextual, linked to experience, past memories and difficult to codify, document and communicate. Unfortunately, there is no universal definition of Knowledge Management (KM), just as there’s no agreement as to what constitutes knowledge in the first place. In broadest context KM is the process through which organizations generate value from their intellectual and knowledge-based assets. It is the practice of harnessing and exploiting intellectual capital to gain competitive advantage and customer commitment through efficiency, innovation and faster and more effective decision-making. Most often, generating value from such assets involves sharing them among employees, departments and even with other companies in an effort to devise best practices.

Today, knowledge is still considered power - an enormous power in fact - but the understanding has changed considerably, particularly from the perspective of organizations. The new paradigm is that within the organization knowledge must be shared in order for it to grow. It has been shown that the organization that shares knowledge among its management and staff grows stronger and becomes more competitive. This is the core of knowledge management - the sharing of knowledge. Knowledge management (KM) is all about managing organization’s knowledge effectively by sharing and having a systematic activity for creation of knowledge and exploiting it for the market and benefit of the organization. KM techniques and processes provide such a structured approach to explicate a significant part of this tactic knowledge document in knowledge repositories and also share in teams, through intensive dialogue and discussions. KM refers to the critical issues of organizational adaptation, survival and competence against discontinuous environmental change.

Introduction

E-Portal otherwise called as an electronic portal is a webpage that allows business application procedure developed by framework to be easily deployed via internet. Portals are usually created in standard Java format. It utilizes an Extensible Mark- up Language (XML) interface protocol in addition to Java Server Pages (JSP). Portals are given different names based on the field they are created. For example, if the portal is developed to improvise agriculture, then they are termed as agri-por- tals. Similarly, if a portal is developed for academic reasons they are called web portal. Examples of web portals are iGoogle, MSNBC, Netvibes, and Yahoo.

Portal concept has opened new possibilities to address some of the issues concern- ing the personal management of academic information and knowledge through internet. Some of the main issues are the lack of integration, personalisation and customisation of existing academic information sources and systems. A Web por- tal can be defined as a Web site that aggregates an array of content and provides a variety of services including search engines, directories, news, e-mail and chat rooms. Portals have evolved to provide a customised gateway to Web information. A high level of personalisation and customisation is possible (Melzer 1999; Boye 1999). It was felt that the portal concept could be further developed to function as a sophisticated Web interface that can support the task performance (teaching and research) of academics.

Introduction

Audiotex is a voice response application that allows users to enter and retrieve information over telephone. Example Interactive Voice Response System (IVRS). Audiotex is a generic name for interactive voice response equipment and service. Audiotex connected with a telephone is like a data processor connected to a data terminal. They are passive service which provides through appropriate access by standardised procedure for the user of Audiotex service to communicate with database via telecom network (i.e.) a subscriber can retrieve the information at any time by interacting with the audio service equipment by using the existing telephone line.

Audiotex is essentially a content provider. It enables the subscribers to record their message in a computer memory area called a “Mail Box”. The recorded message can be retrieved by the recipient by dialling a telephone number. Audiotex service is a telecommunication system which enables a caller, by dialling a designated telephone numbering beginning with ‘1800’ to receive a recorded announcement or to interact with a programme whereby he/she may communicate by means of a dual tone multi frequency telephone key pad, a touch tone telephone or other similar device with a value added network connected to the public switched telephone system for purposes of sending or receiving information. However, there are differing views across the world on what constitutes “Audiotex service”. European Telecommunications Standards Institute in its ETSI technical report 131 (June 1994) on “Terminal Equipment(TE); An investigation into the need for standardization in the area of stored voice services” has commented that “ It can be seen that there are many differing views as to what constitutes an Audiotex service and, in formal usage (e.g. in lectures or articles on the subject), a distinction is always drawn between voice messaging and the other services (information, consultation, transaction, etc.). It is thus misleading to use the word Audiotex without a previous definition. Therefore, in many countries the term “stored voice service” is used to describe Audiotex and each separate application and service is distinguished by a more precise definition.

Introduction

The Kisan Call Centre is an ICT initiative launched by the Department of Agri- culture and Cooperation, Ministry of Agriculture on January 21, 2004 to instantly respond to farmer’s queries in their local language. Farmers from any part of the country can contact KCC simply like common public do to contact the customer care of their preferred network for queries. If it is a BSNL connection KCC can be contacted by just dialling 1551 toll free number. If it is other network, then farmers can dial “1800-180-1551” and get their query solved. In Tamil Nadu, until 2014, it was Cartel India Limited which acted as Level-III centre for Kisan Call Centre in Tamil Nadu. From May 2014 onwards, the administration of Kisan Call Centre was taken over by Indian Farmer Fertilizer Company (IFFCO) and working since then in the name of IFFCO Kisan.

In today’s condition, the policy makers feel it as a real challenge to bridge the com- munication gap that prevails between two farmers, between two villages, between two regions and perhaps between two countries. The only way to bridge this gap is through some ICT initiatives. Recent studies have shown impressive growth of telecommunication network for effective information utilization and delivery of knowledge and information in the country. In Kenya, the helpline service was start- ed on a pilot basis by GSMA Foundation, Inc., which was funded by Rockefeller Foundation. The technology was named Kenya Farmer’s Helpline. It was mainly started to bring a change in the economic, social and environmental development in the country. The helpline received very good support from the local farmers and till 2010, the helpline solved queries of over 30,000 farmers. During the same period, India solved queried of over one lakh farmers. Now, the number would be much more than what we expect.

Introduction

Satellites are specifically made for telecommunication purpose. They are used for mobile applications such as communication to ships, vehicles, planes, hand-held terminals and for TV and radio broadcasting. They are responsible for providing these services to an assigned region (area) on the earth. The power and bandwidth of these satellites depend upon the preferred size of the footprint, complexity of the traffic control protocol schemes and the cost of ground stations. A satellite works most efficiently when the transmissions are focused with a desired area. When the area is focused, then the emissions don’t go outside that designated area and thus minimizing the interference to the other systems. This leads more efficient spectrum usage. Satellite’s antenna patterns play an important role and must be designed to best cover the designated geographical area (which is generally irregular in shape). Satellites should be designed by keeping in mind its usability for short and long term effects throughout its life time. The earth station should be in a position to control the satellite if it drifts from its orbit it is subjected to any kind of drag from the external forces.

The psychological sets that can be barriers to communication can be characterized into several basic categories. These sets can occur in the sender or in the receiver in the communication process. The sender has the ability to recognize these barrier categories when they occur and to transform communication to overcome them. However, the receiver is a different story. If the receiver is interested in communication, he or she can recognize when these barriers arise and can consciously overcome them. On the other hand, when a receiver is passive in the communication process, he or she does not recognize the barriers and the sender can do little to overcome the blockage.

2.1 INTRODUCTION

GIS is a tool that can be used in varied disciplines ranging from civil engineering to business. Remote sensing data is often brought into GIS to have a complete data set in many natural resource application areas. Full capability of GIS is not used widely. Many a times people use GIS only for digitising maps and to do simple query on maps. But it can also be used in modeling, simulation and forecasting, only then one may regard GIS technology is utilised to its full potential. Some GIS softwares handle simple problems for location based services while other complex softwares posses advanced modules to do all types of spatial, network and 3D analysis. Integration of softwares used in natural resources study are being interfaced with GIS to create scenarios.

Remote sensing and GIS technology is useful in the following fields:

1.0 Overview

Natural resources sustain life and are critical for economic development of nations. In developing countries like India where more than half the population is rural, economic development is inextricably linked with agricultural development. In these countries, the food and livelihoods security of the poor are critically associated with access to the services provided by the natural resources - land, soil, water, biodiversity and climate resources. The natural resources are finite, and with increasing population, economic growth, urbanization, and demands for food and other agricultural commodities, these are being increasingly strained. As a result, the productive capacity of the natural resource base is shrinking and deteriorating. Sustaining the productive capacity of natural resources for future generations, while meeting the food and other demands of the growing populations, is the major development challenge of the twenty first century.

In India, during the last forty years the net sown area under agriculture has remained nearly constant at 141 million ha. In the same period, the population has more than doubled (from 541 million in 1970 to 1186 million in 2010) and per capita income grew by more than 3.5 times (from Rs 14824 in 1970 to Rs 53331 in 2010). As available land resources for agriculture are finite, increases in agricultural production to meet the growing demands of the population have to come from intensification of agriculture on the same lands. As a result, the quality of soils on these lands is gradually deteriorating both at the farm and ecosystem levels. The major threats to soil quality come from loss of organic carbon, erosion, nutrient imbalance, compaction, salinization, water-logging, decline in soil bio-diversity, urbanization, and contamination with heavy metals. More than 100 million ha of the total cultivated land of 141 million ha is stated to be under some form of soil degradation.

Similarly, utilizable fresh water resources of India are finite at about 1123 billion cubic meters (BSM), of which about 690 BCM are from surface water resources and 433 BCM are from groundwater. This supply is shared among multiple uses: human and animal consumption, agriculture, urban uses, industry and for provision of environmental services. The total water demand in 2010 is estimated at 710 BCM and is projected to increase to 1180 BCM by 2050. Several parts of India are already facing severe water shortages as a result of the growing demand for water. The quality of water resources is also impacted by agricultural intensification and development, and is increasingly a matter of concern. By the year 2050, when population is expected to stabilize, the shortages will only intensify. The country as whole can be on the verge of becoming a water scarce country, with nearly all the presently estimated utilizable water resources being put to use.

Biodiversity natural resources refer to the abundance of different species and ecosystems in nature. These resources are the primary sources of present and future productive agriculture and human well being, as they provide the basic resources for use in breeding crops and livestock, soil formation and structure, soil fertility, nutrient cycling and the provision of water services. India is among the 12 mega diversity regions of the world. It is known to have more than 18,000 species of higher plants including, 160 major and minor crop species and 325 of their wild relatives. Increasing pressure from human population growth, agricultural intensification, urbanization, pollution and degradation of land, soil and water resources are having a negative impact on the plant, animal and microbial biodiversity resources of the country and their productivity.

Abstract

Soil Resource Appraisal helps in characterizing the existing land resources, assessing their suitability for various land uses and then helping the user to prepare a rational land use plan suitable for the integrated development of the area. Application of Remote Sensing (RS) and Geographical Information System (GIS) helps not only in the characterization of the resource base, but also in the generation of various thematic maps and preparation of land use and action plans for effective implementation of various developmental plans at farm level.

Keywords : Soil Resource Appraisal, Land Use Plan, Farm level Developmental Plans

1.0 Introduction

A thorough knowledge and understanding of soils is basic to the development and management of agricultural resources. About 100 years ago, man began systematic study of soils in the field and tried to separate, classify and map their geographic distri­bution. Today we have sufficient knowledge about soils; however the characterisation, classification and mapping of soils is still tedious, time consuming and costly affair. Therefore the need for adopting new and more rapid and accurate methods of mapping soils has resulted in the use of satellite images with image interpretation techniques for soil survey and map­ping.

In India for the country as a whole, soil and other land resources information is available at 1:1 M scale, which was generated from the state level mapping done at 1:250,000 scale under the Soil Resources Mapping Project of India during the period from 1986 to 1995. This information is of general nature and useful for planning on a wide canvas and not particularly useful for farm or watershed level planning in the country. For site-specific needs and for developmental works at watershed level, we need detailed farm level database at 1:10,000 scale. Once this type of information is generated at village/watershed level, this will be useful for identifying site specific constraints, generation of area and site specific agro technologies, land-use options based on soil site suitability assessment, wasteland identification, identification of prime farm lands and farm clusters for zoning and Strategic planning, preparation of farm level development plans by line departments and proactive advice and technology transfer to farmers.

Abstract

Remote sensing is the art and science of obtaining information about an object or phenomenon without having any contact with the object concerned. Geographical information system is a tool to create, manage, retrieve and query spatial databases. Remote sensing in conjunction with Geographical Information System (GIS) has wide applications in all spheres of life and especially in agriculture. Specifically, this paper reveals some of the applications of remote sensing and GIS in the field of crop condition assessment viz., crop type classification, crop stress detection, crop yield estimation and pest and disease monitoring.

Keywords : Remote Sensing, GIS, Yield Forecasting, Crop Stress, Pest and Disease Monitoring

1.0 Introduction

Remote sensing is the art and science of obtaining information about an object or phenomenon without there being any physical contact. The information is so collected using a device called a sensor. The sensors are mounted on a platform at an advantageous position. Accordingly the remote sensing is called ground based (sensor is hand held or mounted on mast), air borne (sensor is on a balloon or aero plane) or space borne (sensor is mounted on a satellite). The basic principle in remote sensing is that each and every object has unique reflecting property like human thumb impression and when the solar energy is falling on an object a part of it gets reflected, which carries the information about the object. The reflected light is converted in to reflection percentage of incoming solar radiation. This percentage of reflection can be used to work out the vegetation indices which are surrogate measure of crop condition.

Geographical Information System (GIS) is software system which enable Collection of large volume of data with spatial relation Integration of data from different source is possible Analyze such data for our requirement Present the data in different formats (maps, table and reports)

THEORETICAL ORIENTATION

The word “democracy” is derived from the Greek roots - ‘cracy’ meaning ‘rule of and ‘demos’ meaning ‘the people’. It is governance of the people, by the people, for the people. Rule by majority is, no doubt, an important feature of this system of governance; but the more important ingredient is rule by consultation - consultation between the people’s representatives on one hand and consultation with the officers on the other. ‘Decentralization’ means devolution of central authority among local units close to the areas served. Where authority is devolved by this process on people’s institution, it is ‘democratic decentralization’.

At the instance of the Prime Minister it was decided to give the process of the three-tier administration the strictly Indian name, “Panchayati Raj” which means a system of government. Panchayati Raj was conceived system of democratic local self-Government. Earlier, Mahatma Gandhi also advocated panchayati raj as the foundation of India’s political system, as a decentralized form of government in which each village would be responsible for its own affairs. The term for such a vision was Gram Swaraj (“village self-governance”). The institution of Panchayat represented not only the collective will, but also the collective wisdom of the entire rural community.

The Balwant Rai Mehta Committee, headed by M P Balwant Rai Mehta, was a committee appointed by the Government of India in January 1957 to examine the work of the Community Development Programme (1952) and the National Extension Service (1953) and to suggest measures for their better work. The committee recommended the establishment of the scheme of ‘democratic decentralisation’ which finally came to be known as 'Panchayati Raj' which would be a 3-tier system - 'Gram Panchayat' at the village level, Panchayat Samiti at the block level, and Zilla Parishad at the district level.

1.1 R and R studio

R has become the world-wide language for statistics, predictive analytics, and data visualization. R is not limited to statistics; it has a wide range of tools for spatial analysis and digital image analysis and can handle any process needed for image analysis flexibly. It offers a wide range of methodologies for digital image processing, from the most basic to the most complex. As an open source project, it’s freely available for a range of platforms, including Windows, Mac OS X, and Linux. An integrated development environment (IDE) for R, R Studio, allows interactive execution of R functions with user interface. RStudio is available in two formats - RStudio Desktop and RStudio Server - both available in free and fee-based (commercial) editions.

1.1.1. Download and install R

The R software setup files can be downloaded from any of the widely distributed Comprehensive R Archive Network (CRAN). To download R, please choose your preferred CRAN mirror, a location close to you. Follow the following steps:

Sensors onboard the satellite records the intensity of emitted or reflected electromagnetic radiations in the form of digital number (DN) for each pixel. These digital numbers can be transformed to more meaningful intensity units like radiance or reflectance. This process of conversion of digital numbers to radiance or reflectance is known as radiometric calibration. Sensor specific information is required to conduct radiometric calibration.

Mosaic is the combination of two or more raster images into single image. Sometimes, single image captured by remote sensing satellite doesn’t completely covers the desired study area mostly. Therefore, users resort for mosaicking two or more images captured by satellite sensors from different paths so that the whole study area is merged into a single raster image to facilitate the image processing and analysis. The pixel size of the raster images should be same for mosaicking.

In most of the cases, there is spatial overlapping among the raster images from which we want to create mosaic. These overlapping areas are handled in multiple ways which is being discussed further using R – code example. For mosaicking raster images in R, mosaic function of the raster package is used.

Abstract

Women in India constitute a larger proportion of total unemployed population and hence it is imperative to find out the entrepreneurial problems faced by them. A study was conducted with the objectives to ascertain the financial, marketing and production problems faced by women in their enterprises and assessment of their health status and work place facilities. Boutiques, beauty parlors, embroidery units, fruit and vegetable preservation units and artificial jewelry making were the enterprises selected for study. The results of the study revealed that women faced problems in areas like finance, marketing, health, work place and production. Some recommendations of the study are a) Women entrepreneurs should keep abreast of knowledge about new techniques, financial institutions, training institutions and marketing linkages. b) Information about site or location, physical facilities, transportation etc. must be collected prior to selection of area for development of an enterprise. c) Self help mutually aided groups must be formulated for overcoming common entrepreneurial problems. d) Women should shift to the non-traditional sectors of entrepreneurship in order to earn more.

Abstract

Participation of rural women and youth in beekeeping activities provides a unique opportunity to improve rural livelihood and poverty reduction. Women have explored their own niche in beekeeping industry by actively engaging in post harvesting of bee products. Income generation is one of the major reasons for participating in beekeeping activities and beekeeping was ranked number one at the same level as agriculture as major source of income. Post harvesting beekeeping, however, needs liquid capital investment which, limit women and youth to fully participate in the business. Cultural practices are also one of the main hindrances for adult women and youth to participate in beekeeping activities. Nonetheless, presence of beekeeping groups and associations, community banks, forest reserves and beekeeping awareness campaigns in the areas provided opportunities for women and youth to participate in beekeeping. Beekeeping represents one opportunity for income generation which need not be time consuming and can fit in well with women’s priority activities. women be given the opportunity to start beekeeping, it is important that all beekeeping development programs ensure from the outset that extension messages reach rural women, and that they are able to take full advantage of training and credit facilities.

In soil culture, also known as in-ground culture, crops are raised on level ground as well as in raised beds. Soil culture is more often used in growing vegetables (e.g., tomatoes, lettuce, cucumbers, and peppers) rather than ornamental crops such as herbs, roses, freesia, and foliage plants as well as popular with smaller commercial and organic growers. The soil should be well drained, fertile, have a medium to light texture and be high in organic matter. The soil in a greenhouse should be worked as deeply as possible to break any existing hardpans or those that may have developed because of repeated traffic over the area. Fumigation or pasteurization of the soil is a must before each crop or at least once a year. This will help to destroy disease, nematodes and weeds. If soil is steamed, hold it at 180 degrees F (82°C) for 4 hours. Production techniques used in soil culture are similar to intensive crop production methods used in the field. Although soil is readily available at most places where a greenhouse is located most commercial growers, no longer rely on soil culture in the greenhouse as they did ealier. Some of the reasons include insect and disease pressures and costly fumigation.

There are different types of greenhouses, the low cost and high cost or low technology or high technology greenhouses. The cost of greenhouse and expenditure on crop production under these greenhouses would vary according to technology to be used and the crop is to be produced. The cost would vary from place to place with location of greenhouse. For each type of greenhouse its cost would vary according to geo-climate, the production practices and input expenditure/availability. The cost of construction of greenhouse in 2019 hence varies from Rupees 500 to 6000 per square meter.

Introduction

The search for order in the location and size of settlements continues. Certain geographers examined the size of distribution of settlements and described in graphical form the relationship between the number and size of settlements. Their methods were radically different in that they were not deterministic, rather than making a set of assumptions, deriving a theory and testing it against reality, they observed the size and number of settlements in various countries and noted a common characteristic, which was called the rank size rule. Having once observed this order in the real world, they then sought to explain it. A relationship which is observed on several occasions is called an empirical regularity. The rank size rule is one such empirical regularity.

The rank size rule was first observed by Auerbach in 1913 but was proposed and popularized by G.K. Zipf in his book “Human Behaviour and the Principle of Least Effort”. Since then, many writers have attempted to explain it but the basic aim has always remained the same: to find a graphical description to the size distribution of cities which would apply to the situation prevailing in many countries.

Rank Size Rule: Theoretical Base and Concept

Rank size rule is a theory describing numerical distribution of settlement, which recognises an empirical regularity whereby the product obtained by multiplying a city’s rank by its size is equal to a constant, the population of the country’s largest city such that for a given settlement system

Thomas Robert Malthus enunciated his views about population in his famous book, Essay on the Principle of Population as it affects the Future Improvement of Society, published in 1798. Malthus revolted against the prevailing optimism shared by his father and Godwin that a perfect state could be attained if human restraints could be removed.

Malthus’ objection was that the pressure of increasing population on the food supply would destroy perfection and there would be misery in the world. Malthus was severely criticised for his pessimistic views which led him to travel on the continent of Europe to gather data in support of his thesis. He incorporated his researches in the second edition of his Essay published in 1803.

The Malthusian theory of population is the most well-known theory on population in economics. Malthus pointed out that an accelerated increase in population would outweigh the increase in food production. This would have an adverse impact on the development of an economy. The Malthusian theory explains the relationship between the growth in food supply and in population. It states that population increase faster than food supply and if unchecked leads to vice or misery. This theory is explained in the following propositions

1. Introduction

Agricultural mechanization refers to usage of any improved tool, implement and machine by the farm workers to improve the efficiency of any operation to increase productivity. It also helps to reduce drudgery or stress which adversely affects human mental faculties leading to errors, imprecision and hazards and eventually loss of efficiency if done manually. In developed countries, however, mechanization is synonymous to automation. There is scope to mechanize every operation of crop production, post harvest and agro-processing.

18.1. What?

The basic objective of sowing is to place the seed in rows at the desired depth, to maintain proper spacing between seed to seed, cover the seeds with soil and provide proper compaction over the seed if required. Precise sowing/planting helps in better crop stand. This helps to achieve optimum yields. Traditional sowing methods include broadcasting manually, opening furrows by a country plough and dropping seeds by hand (i.e.) dibbling. In the present day, improved seed-cum-fertilizer drills are used for sowing and fertilizer application. These are provided with seed and fertilizer boxes, metering mechanism, furrow openers, covering devices, frame, ground drive system and controls for variation of seed and fertilizer rates.

18.2. Types of sowing/planting equipment

Sowing equipment include seeders and transplanters. Various types of sowing equipment, viz., manually operated, animal drawn, power operated and tractor drawn are used throughout India.

18.2.1. Seed drills

Seeders are available for sowing seeds of various crops. Some seeders have been designed with adjustable metering mechanism which makes them versatile for sowing two or three kinds of seeds. For example, a multicrop planter developed by CIAE is used for sowing garlic, maize, moong, peas and groundnut. Similarly, the institute has developed a small seed sowing drill which is used for sowing small seeds such as bajra, rapeseed and mustard.

21.1. What?

Harvest is the process of gathering the end produce from mature crops in the fields. Harvest marks the end of the growing season, or the growing cycle for a particular crop. Harvesting is the most labour-intensive activity. Moreover, timely harvest before shattering of the produce or before rain assumes significance. As adjacent fields sown at the same time come to harvest simultaneously, farmers face great problem in getting manual labour for harvesting and cleaning their produce. To overcome these difficulties, different types of harvesters have been developed from time and again to suit different crops, situation and conditions.

21.2. Harvester and reaper

Harvesters are used to cut the crop after they mature. In such cases, threshing is to be done separately. Harvesters are available for a wide range of crops belonging to cereals, pulses, millets, oilseeds, fruits and plantation crops. Reapers are used to harvest crops such as rice, wheat, soybean, mustard, rapeseed, safflower and other thin stemmed crops. Reapers are operated using power tiller.

The study entitled “SHG in Techno Economic Empowerment of Tribal Women” was conducted on the following specific objectives.

Empowerment of women in relation to SHG (ii) Profile of SHG

Structure and functions of SHG

SWOT analysis of SHG

Constraints of SHG and suggestion

Case studies

SWOT analysis is the systematic identification of the internal strength and weakness of an organization or enterprise and environmental opportunities and threats. The analysis is based on the assumption that effective strategy maximizes strength and opportunities and simultaneously minimizes its weakness and threats. Entrepreneurial activities require a SWOT before initiation to provide first hand information about feasibility of the enterprise. All SHGs in rural sector are formed for income generation. A variety of enterprises coming up through SHG in rural sector may or may not be successful. SWOT provides basic direction for entrepreneurship at any level for benefit of the practitioners. The SWOT of SHG in tribal area where study was conducted has been analyzed.

The problems of SHG are many and diversified. The problems vary from place to place and SHG to SHG. Then problems cluster is in relation to economic productivity, overall welfare and livelihood. As we observe since five decades after independence, resistance of people in the state of social, economic, political disempowerment is considered to measure hindrance to overall development. The SHG being a part of society is not an exception to be cited with problem. During investigation the constraints experienced by SHGs members are categorized under five areas namely personal, social, economical, technological and marketing problem. These problem directly and indirectly affects the performance of SHGs. The evidences of past studies and experience in the present context reveal a wide variation in the dimension of the problem.

Verbal communication-definition and meaning-Verbal vs Oral communication - Types-Styles-Barriers to effective verbal communication

Meaning

Verbal communication takes place directly between the superiors and juniors in organizations and between farmers and extension functionaries in the field and is often known as face to face communication. It takes the form of talks, a public address, verbal discussions, telephonic talks, telecommunications and other forms such as audio-visual aids speeches and orders, holdings of meetings and conferences, lectures, social get-togethers, training sessions, public address systems, museums, counseling etc.

Though technically, written communication is nonverbal, it falls under this category as it includes the use of words and language. Few examples of verbal (written) communication are books, letters, text, newspapers, etc.

It is a primary record of research. Researchers use a lab note book to document their hypotheses, experiments and initial analysis or interpretation of these experiments.

Laboratory Record

The following is a general description of how to keep a proper laboratory notebook. Requirements for different teaching, research, clinical, or industrial labs will most likely vary. Some institutions/labs will require less stringent record keeping, others will hold you to a very strict protocol. A well kept notebook provides a reliable reference for writing up materials and methods and results for a study. It is a legally valid record that preserves your rights or those of an employer or academic investigator to your discoveries. A comprehensive notebook permits one to reproduce any part of a methodology completely and accurately.

Definitions

The word abstract comes from the Latin word abstractum, which means a condensed form of a longer piece of writing. Abstracts are important parts of reports and research papers and sometimes academic assignments. The abstract is often the last item that you write, but the first thing people read when they want to have a quick overview of the whole paper. We suggest you leave writing the abstract to the end, because you will have a clearer picture of all your findings and conclusions.

An abstract is a paragraph that provides an overview of a paper. Abstracts should be between 100 and 200 words long and usually contain a list of keywords at the end to help readers identify the main points of the paper. While abstract requirements differ across academic disciplines, there are two main types of abstracts: humanities abstracts and scientific abstracts.

Purpose of abstracts?

Abstracts typically serve five main goals:

ABSTRACT

With the advancement of mobile technology, the usage of mobile application has increased significantly which leads to change the life style of common people. Library is also not an exception in this context. Library and Information Science Professionals have started to incorporate the changes from the beginning of ICT advancement with an idea “library should be within thumb of people”. Mobile application plays vital role to fulfil the objective of library. Most of the library has started or planning to start the service to its user with various services effectively. But, the process to provide library service through mobile application is not satisfactory till date. No too much usage of libraries mobile apps can be seen; even which mobile applications are in use, most of them are almost inactive form.

But the various recent surveys show us the tremendous growth of the usage of mobile application among people. According to Google, (2017) the user survey shows that mobile can fast-track time to purchase by 20% through facilitating efficiencies in decision-making and enhanced team collaboration, particularly with more complex purchases.

ABSTRACT

Academic libraries are unique, essential and strategic hubs inside our social cloth which are advanced primarily based totally at the requirements of the times, to help people in the purchase of good enough facts that could allow them to decorate their information, for the development in their wellness and that of the society at large. To attain their goal, they ought to generate, filter, control and diffuse correct and well timed human information which have been harvested and documented; for the purpose of enriching the highbrow needs in their clients. Like every other kind of library, academic libraries are growing organisms. Justification to the above statement has been captured aptly in the classic book of Ranganathan (1931) entitled ‘Five Laws of Library Science’; detailing the principles of the library profession. The philosophical postulation of Ranganathan’s fifth law is a classical position that offers much strength and support for the need to adequately plan for the best strategies to exhibit in academic library environments in order to provide effective services. In other words, the fore-stated law by Ranganathan has already signaled that academic librarians must be ready at all times to effectively satisfy the diverse, complex and ever-increasing information needs of their users from the explosive available information resources that spring on a daily basis. As such, addressing this issue would require a holistic management approach by academic libraries that must be internally efficient and externally effective.

ABSTRACT

It is very important for every library to have all the resources/materials necessary to fulfil its target. The working of a library can be classified into two forms: dealing with the users and behind the scene. There are numerous different sections in a library divided on the basis of their functions. Most important of these is the Acquisition section. A library’s success lies in a well organized acquisition section. Main aim of the library is the contentment of the users. However, collection development is the primary task of the acquisition section which further contributes to user satisfaction itself. It performs the process of selection, procurement and accessioning of reading materials as well as maintains records. It organizes the monetary as well as human resources in such a manner that collection is facilitated more and that too in an economic and less time consuming way. All this is the responsibility of the librarian. Before acquiring the reading materials, the librarian is supposed to decide that which items are actually required in the library and which are to be rejected. A librarian must study the requirements of the library and acquire materials as per the priorities of the institution to achieve its goal.
