1. GEOLOGY

Geology : Earth Science

 Geo = Earth + Logos = Science

 Def : The science which investigates the history of the earth is known as geology.

 Following are the important branches of geology.

1.Coal Geology : it is related with natural gas, coal deposits and their formation.

2.Crystallography : includes the crystal and atomic structure of the mineral. 3. Drilling Technology : it is related with the cores, core logging and coorelation of the lithology.

4.Engineering Geology and Surveying : it is related with engineering aspects of the earth.

9. WEATHERING

The general process of production of rock waste partly by mechanical breaking and partly by chemical decomposition is known as weathering. The resulting products of weathering accumulate in the same place from which they are derived and there is no transport involved in the process.

Agents and types of weathering : The agencies which are involved in the process of weathering are atmosphere, water and organisms. The whole process of weathering may be conveniently divided into two types : mechanical or physical weathering and chemical weathering. Mechanical weathering involves those processes which bring about disintegration of rocks and minerals without any chemical activity. Chemical weathering involves various chemical processes which slowly decompose the rocks and minerals. In nature two processes are intimately associated and only under extreme conditions, they do occur as a separate entities. Mechanical weathering breaks down the rock creating more surface area and facilitates chemical weathering. Chemical weathering weakens the rock and makes it more susceptible to mechanical break down. Thus the two processes are always complementary to each other.

19. PHYSICAL PROPERTIES OF MINERALS

Def : The minerals are naturally occurring solid bodies having definite chemical composition and certain atomic arrangement, and are formed by inorganic processes in the nature.

All the minerals possess certain physical properties which are considered as follows.

1.Characters depending upon light such as colour streak, luster, transparency, translucency, phosphorescence and fluorescence.

2.Characters depending upon certain senses such as taste, odour and feel.

3.Characters depending upon the atomic structure and state of aggregation such as form, hardness, tenacity, fracture, cleavage and surface tension effects.

On the basis of these three characteristics, the minerals are identified and distinguished.

24. IGNEOUS ROCKS

Introduction : Petros = rocks and logos = science

Petrology means the science of rocks. It deals with the mode of occurrence composition, classification and origin of rocks and their relation to geological processes and history of the earth.

Rocks can be studies in two ways : The study of rocks as specimens in the laboratory is called Petrography which places emphasis on the purely descriptive part from textural mineralogical and chemical point of view. Petrogenesis deals with the origin and processes of formation of rocks. Petrology is a broader term which includes both petrography and petrogenesis.

Igneous rocks are formed by cooling and solidification of magma, either underneath the earth’s surface or above the earth’s surface.

27. STRIKE AND DIP

Outcrop : A part of the rock formation which crops out or exposed on the surface of the earth is called an outcrop.

The total area over which a particular rock unit occurs at the surface whether visibly exposed or not. The term outcrop is especially used for delination of such an area on a geological map.

Attitude : To study these outcrops their attitude help in better understanding the position of the bed on the ground surface or in field is attitude of a bed can be described with the help of two basic structural elements i.e. strike and dip.

33. GEOTECTONICS

Introduction

Geotectonics is the branch of geology which deals with the structure and movements of the earth’s crust. It includes the study of large-scale features like mountain chains, mid-oceanic ridge and oceanic trenches. Investigation regarding the form, pattern and genesis of these, and other tectonic units have enabled geo-scientists to ascertain the important characteristics of earth’s crust and reconstructs its evolution and geological history.

New Recently developed amplifiers and filters are also included. Development in oscillographic elements and cameras are discussed. Other information includes, the recently reported Array Technology and Space Technology for measurement of seismic signals.

Abstract

This chapter will look at the major reasons why farmers in India are unable to take advantage of Agricultural profession as a mode of generating income and suggest ways to change this by employing new technologies. Agriculture has basic processes which require identifying the season for planting the seeds at the right time, watering the plants to the required level, undertaking maintenance for the different plants and then finally harvesting at the right time to ensure that the effort that has been put into the agricultural process results in useful output. In business terms the output when it is valued in terms of money, should enable the farming business to sell their output at a certain price that will enable them to pay off the money that has been used for setting up the crop for that cycle. This chapter will underscore the valuable contribution of remote sensing data in farming to enhance operational decisions. We will look at how low-cost technologies can be implemented into the existing agricultural extension activities and help farmers make better decisions that will enable them to be more business oriented. It is envisaged that incorporating high technology-based data into simple to understand terminology willhelp reduce the burden on farmers. This is due to the lack of knowledge but also due to the low volume of information that is possible to be fed to the farmers through the agriculture extension network in the country. However, due to the varied nature of farming in India it is difficult for extension officers to specialise but concentrate their efforts on widely utilised crops in an area. The following figure below explains in simple terms how the cycle of activities occur in a farmer’s world and where business decisions are taken that will have an impact on the profitability.

Abstract

The upsurge in global population rates has triggered a significant escalation in food demand across the world. This is accompanied by urbanisation and a pressing need for sustainable agriculture. In this context vertical cultivation of plants as well as breeding of livestock on vertically inclined surfaces, such as in skyscrapers and other high-rise buildings in urban regions has gained prominence. The dynamics of urban agriculture is captured through the case study of Urbagrow Aquaponics, an urban, aquaponic, soil-free, food garden based in Kolkata. The garden exhibits an assortment of aquaponic systems for growing a variety of vegetables as well as the tilapia and catfish. The systems make use of less water, require less work in man-hours and can grow vegetables in greater density than a traditional soil based food growing endeavour. A feasibility study has been conducted to explore the potential of scaling such a venture across myriad other high-rise buildings across Indian cities.

Abstract

Sustainable development and success in any field, agriculture being one of them, goes hand in hand with Innovation. To tackle the current growing problems in the agricultural sector, and long-term sustainability of the agri-ecosystem, agricultural innovations are needed that might bring new products or processes or open up new markets, thereby optimising the use of the limited resources to attain maximum benefits. The authors discuss innovation from the perspective of two dimensions: Technology and Market to illustrate four different kinds of innovation - incremental, architectural, radial and descriptive. This paper deals with the concept of innovation in agricultural field [referred to as agri-innovation] using illustrations of two innovative products namely Dragon Fruit and Water Hyacinth, both of which have significant role in the agri-ecosystem of India. The introduction of Dragon Fruit in a new market is illustrated as an agri-innovation. Efforts by state and private sector of introducing Dragon Fruit, a popular production in South & South East Asia to Indian markets are an example of Architectural Innovation. Also the most common weed Water Hyacinth is considered to be used in news forms so that it can be modified as a new product for a new market. The paper thus documents the suitability of these innovative agri-products in the current Indian market scenario.

Abstract

Access to reliable and affordable irrigation is one of the most important enablers to increase agricultural productivity and income for farmers. An innovative Manual Axis Tracking Solar Pump model and its utility in providing affordable irrigation has been discussed in this paper. The proposed Manual Axis Tracking Solar Pump can increase output on an average 8%-12% more than fixed panel and is much cheaper than automated tracking. This paper deliberates upon the technical features that make the Manual Axis Tracking Solar Pump an advantage over its nearest competitor, the diesel pump. Government of India has already introduced various subsidy-based solar pump schemes and most of them are not popular because of low discharge issue. The low discharge issue can be solved by this proposed optimum tilt-based Manual Tracking Solar Pump, whose sustainable market penetration is suggested through various strategies in the paper, supported by case studies. The proposed entrepreneurship model not only opens a new era of agricultural business but also helps to reduce the GHG emissions.

Abstract

More than one-third of food is lost or wasted in post-harvest operations in India. Decreasing the post-harvest losses (PHL) may be a sustainable solution to increasing food availability and improving farmers’livelihoods. As per Associated Chambers of Commerce of India, India loses approximately US$ 14.33 billion annually on account of PHL (ASSOCHAM, 2017). The objective of this study is to analyse the agricultural wastes that are produced in the value chain for a modern trade retailer, identify their causes, and discuss methods for minimising field wastages. A case study approach has been used to depict the agricultural value chain (vegetable segment). A field visit was conducted to a farmland and a privately operated Collection Center in Barasat area of West Bengal. The author discusses solutions towards minimising harvest wastages in the farm by focusing on waste reduction. Post-harvest wastages beyond the farm can be reduced by undertaking measures that focus on waste management. Going forward, adoption of technologies by farmers may lessen inefficiencies such as wastages and improve their income. Further scope for research lies in exploring joint interventions by private players, government agencies, non-profit organisations and entrepreneurs through public-private partnership models or through development of clusters for creating sustainable value chains and achieving greater profitability.

Abstract

Packaging industry is considered to be one of the world’s largest industrial sectors. In the past few years, food processing has undergone several paradigm changes with respect to production, distribution, storage, processing and retailing. This increasing dynamism in the food industry, while on one hand placing a lot of challenges on the packaging industries, is on the other hand opening up opportunities for entrepreneurs to foray into food processing and also packaging industries and develop appropriate solutions in response to the needs of the market and environment. This study aims at exploring the state of packaging industry and packaging technologies in developing countries, with special emphasis on India, against the backdrop of increasing concern for prevention of food losses and therefore highlighting the need for new innovative ideas for food packaging. The authors posit that customer awareness about safety of processed food has given rise to tremendous possibilities of entrepreneurship opportunities in the area of safe and hygiene packaging. However market preferences, state reputations and cost benefit analysis play major roles in packaging of processed food products.

Abstract

Entrepreneurship essentially involves economic and dynamic activities, risk- assuming and idea generation that help in developing, organising and managing a business opportunity for profits. Entrepreneurship in agriculture is not merely confined to farm activities but also involves activities interlinked and interdependent with core and peripheral agricultural activities. Impediments in the pathway of agricultural entrepreneurship in West Bengal are characterised by fragmented landholding, low financial resources and thereby debt stickiness & dependence on short-term agricultural loan. Though disbursements of short-term credit have increased substantially, the rate of increase is low. For most farmers, insurance for financial or crop crisis is unheard or have hardly any implication. The paper tries to explain the performance of various agricultural insurance schemes in terms of coverage and the benefits being delivered in India and in West Bengal. The paper analyses whether the recipients consider the schemes as an effective risk mitigation tool or merely a habit of credit-dependence in West Bengal through a diffusion model. The paper concludes with the focus on possible entrepreneurial opportunities that may offer more customised agri-insurance policies, where regional disparities could be considered and individual interests be given little more importance.

Abstract

Among the 29 Indian states, 14 are linked with 585 regulated mandis with electronic national agricultural market. Across the states, 7.35 million farmers with 53,163 commission agents are registered in these regulated mandis. Every year Government of India announces modified agricultural policies to safeguard the interest of the farming community. Amongst the policies, one of the mechanisms to protect the producers from price fluctuations is Minimum Support Price (MSP). While determining MSP, government takes into account cost of production, cost of living, as well as economic and socio-political factors. For the past two decades, it has been observed that one MSP graph is moving upward but still the farming community seems dissatisfied. The reasons behind MSP variation among states include offering bonus prices additionally with MSP by some states, due to variation in government procurement procedures and policies. As a result, MSP is playing an important role in manoeuvring of prices amongst the various state markets. MSP deviation provides chances for the private sector to take undue advantage and the farmers are adversely affected. The study analyses existence of deviation in mandi prices of staple food between two states from year 2007 to 2018. It will disclose whether centralized price system reduce the cost of government and aid the farmer to get fair valuation.

Abstract

Trade Related Agreements on Intellectual Property Rights (TRIPS) widely affects the agricultural sector which is largely unorganised in India. At the same time this sector remains the bread winner for majority of the population of the country. The Intellectual Property Rights (IPRs) affect the extensive and intensive margins in agricultural trade. This paper draws attention of enterprises in the field of agricultural biotechnology which has genetic modification (GM) as one of its core activity. GM is of benefit in terms of value additive features but also of great concern for the community in conservation of biodiversity. Food & Agricultural Organisation (FAO), being aware of the pitfalls of implementing IPRs in agriculture, constituted an expert panel to study the issues pertaining to the sector. They came up with very clear directives to the FAO on the course of action. This paper aims to focus on this area to identify the micro-level dynamics of IPRs in agriculture and its effects on the rural enterprises in India. The impact of IPRs and its ramifications, the issues of agricultural productivity and its future trajectory, are to be understood from the perspective of an entrepreneur’s policy decisions. This will lead to identification of policies that would help in harnessing IPRs for the growth of Indian agriculture.

Abstract

The agriculture and allied sector provide livelihood for 58% of India’s population. A large population and rising disposable incomes are key growth drivers. Growing external demand has increased its contribution to exports. The demand for processed food has also led to increasing requirements for agricultural inputs, hybrid seeds, machinery and fertilizers. Investment opportunities in storage infrastructure and agrochemicals also present immense opportunities. Organised retail has made India attractive for multinationals. The industry has a combination of multiple organisational forms, like associations, co-operatives, government (departmental) undertakings, foreign entities, trusts and companies, private and public. Unlisted companies encompass a vast range (private limited companies, family business, group-owned firms, and joint ventures are major actors.) The form and complexity of business ownership highlights Corporate Governance (CG) debate. Given this background, our objective is to understand the CG characteristics of unlisted agricultural and allied companies operating in India, the driving forces for improving CG practices, and the need for a policy framework in supporting good CG. We propose to examine the extent of control in the various types of entities and explore the mechanisms that contribute to the development of an efficient CG framework. Using data from the Prowess database, on 2,879 firms, from 2012-2013 to 2016-17, we analysed how CG problems are caused and how it can be alleviated. The results provide stakeholders and agri entrepreneurs with an overview of the policy and managerial issues that arise in the debate on CG of companies in this key sector. Finally, we conclude how the unlisted companies are likely to stimulate growth and development if CG mechanisms are enhanced.

Abstract

This paper is rooted in the issue of the failure of Green Revolution which was intended to achieve self-sufficiency in the agriculturally dominant country of India, following its independence. However five decades later, the current focus of the country is on engaging in a sustainable and economically feasible agricultural practice using principles of agro ecology. This paper tries to explore the potential of application of organic farming in a vast country like India. The author posits that organic farming can help India reverse the damage caused by Green Revolution by allowing for natural methods of agriculture rather than a severely mechanical form. This paper focuses on the modern concept of organic farming combining tradition, science and innovation, and the debatable issues surrounding organic farming particularly dealing with its economic feasibility and sustainability prospects. It is acknowledged that for the successful implementation of organic farming there has to be appropriate matching of the supply and demands the organic products. However, there is a need to address the challenge of adoption of organic farming in a diverse country like India because of its huge variance in education, income, living standards and health of the existing and potential consumers. The prospect of organic farming is discussed from the perspective of consumer awareness and state initiatives, in this paper.

Abstract

Agriculture is the backbone of India’s economic development and has experienced immense growth in the past few decades. Agriculture not only involves the participation of male workers but also experiences active participation of all family members, as well. Women, as part of the family, take up agricultural activities as an extension to their household chores. The Government and voluntary agencies have also recognised the need for women in the farming community to become self-reliant and active participants in the agricultural sector. Increasing awareness and educating themselves with the passage of time, farmers have made themselves aware of new techniques of farming and growing and established themselves as agricultural entrepreneurs in the long run. Many initiatives supporting women entrepreneurs and creating a supportive ecosystem for women to become agricultural entrepreneurs have been initiated by the state. The case of Anita Devi popularly known as the Mushroom Lady of Bihar has been taken up in this paper to substantiate with evidence how government initiatives have helped her gain success and grow as an agricultural entrepreneur. This study aims at disseminating how such initiatives help in creating an ecosystem that motivates agricultural entrepreneurs in general and women in particular.

Abstract

Out of 1.37 billion populationof India 67 % lives in rural areas whose major source of income is agriculture and allied activities (World Population Review, 2019). In simple words, the livelihood of this vast majority is closely related to rural enterprises. Fostering rural entrepreneurship may be affected by several issues, infrastructure being one of them. This paper attempts to examine the relationship between infrastructure investment by the state and rural entrepreneurship in India, with ‘Gross Fixed Capital Formation’ and ‘Agriculture, Forestry, and Fishing, Value Added’ considered as proxy variables. Time series econometrics is compiled with the data collected from World Bank Database for the period of 1961-2017. The study has established evidence in support of greater investment in infrastructure enhancing rural entrepreneurial opportunities in India.

Abstract

India is the second largest food producing country in the world. Food processing is one of the key industries in the country and a sector that has direct linkage between agriculture and industry. Being the second largest producer of fruits and vegetables along with its strategic geographic location and proximity to food importing nations, India is in an advantageous position in terms of exporting processed food. As per estimates, Indian food processing sector stood at USD258 billion in the financial year 2015. The growth and development of this industry have direct impact on the Indian economy. The aim of the present study is to discuss about the growth of the food processing industry, analyse its strengths and weaknesses and generate possibilities of entrepreneurial development towards the expansion of the sector. This study has been a secondary data analysis based on data collected from journals, magazines, web searches and reports from various government and private agencies.

The study has identified the main drivers aiding to the growth of the sector. It includes strong domestic demand, rising export opportunities; supply side advantages for exporters due to rising global demand and strong policy support from the Government. On the other hand, fragmented market, infrastructure support, namely cold chain, innovation and skill development are the major hurdles that have to be overcome. This article makes an attempt to explore entrepreneurial opportunities and few areas where new business could be initiated. The entrepreneurial opportunities highlighted in this paper are based on Drucker’s opportunity construct that entrepreneurs have an eye more for possibilities created by change than the problems.
