Globally saffron (Crocus sativus L.) is cultivated in regions spanning from the Mediterranean in the west to Kashmir in the east. Countries like Iran, Spain, Italy, India, Greece, Turkey, Afghanistan, Morocco and Azerbaijan harbour suitable climatic and soil conditions required for its growth and harvesting (Mehdi and Reza, 2012). However, the crop is also cultivated on small scales inFrance, Switzerland, Israel, Pakistan, China, Egypt, United Arab Emirates and Japan. Recently its cultivation has been introduced in non-traditional countries like Australia, New Zealand, USA, Argentina and Chile (Fernandez, 2004). Globally, about 85 thousand hectares of land is under saffron cultivation, giving a produce of 288 MT. Iran leads with 90 per cent of total global share for saffron production (Baghalian et al., 2010) and 70% of global export earning a revenue of US$ 51million. India’s global share is about 4.5 per cent in production followed by Greece (2.5%), Morocco (0.9%), Spain (0.8%), Italy and China (0.3% each), Afghanistan (0.2%) and Azerbaijan (0.06%).

Cheese, butter, whole milk powder, and skimmed milk powder are a major part of the world’s dairy trade. The demand for worldwide dairy exports is highly concentrated. With a share of 12 per cent, New Zealand is the largest exporter of dairy products, followed by Germany, Netherlands, France and the US. Germany has been the world’s major dairy importer as well with a share of 10 per cent. Other large dairy product importers are China, Netherlands, France, Italy and Belgium.

Before 1999, India was a net importer of dairy products. The successful implementation of the ‘Operation Flood’ program and trade reforms caused the direction of India’s dairy trade to change marginally. India has been a net exporter of dairy products since 2000. Statistics show that India’s export share of dairy products over world dairy exports increased marginally from 0.1 per cent in 2001 to 0.5 per cent in 2019, while its import share of dairy products over world dairy imports increased marginally from 0.018 per cent in 2001 to 0.04 per cent in 2019. The Middle East, South Asia, South East Asia, and the USA are the major markets for India’s dairy products. Conversely, India is a favorable market for the European Union, New Zealand, Australia, UAE, and US dairy products.

Introduction

Fish and the aquaculture products contribute a significant amount of animal protein to the diet of the people worldwide. Being highly nutritive they serve as valuable food supplement in diets lacking essential vitamins and minerals. Besides its role of food security, fish is a source of income for millions of people around the World. Though the trade is not prominent at Global level, in some countries its contribution to foreign currency earning is vital to the National Economy. India has a coastline measuring 7500 km and important aquaculture country in the World. Being the home for more than 10% of the global fish biodiversity, the country ranks third in the World in the total fish production with an annual fish production of about 6.4 million tones. Constituting over the 1% of the GDP, fisheries contributes to 5.3% of the agricultural GDP. The estimated foreign earning for the year 2006 was US$ 1365 million.

India is an agricultural country. The geographical area of India is about 328 mha out of which 147 mha of land under cultivation and 84-mha land is under irrigation. The population is increasing at an alarming rate that requires producing more food for the growing population. This problem can be solved either by increasing the land under irrigation or using different soil water conservation techniques. It is well known fact that during rainfall a considerable amount of water goes to sea due to high rate of runoff. It is highly needed to trap as much as water falling in the form of rainfall and recharge the groundwater so that it is made available for irrigation purposes.

Weeds have been existing on the earth ever since the man started domesticating /cultivating plants and animals around 10,000 B.C. and recognized as a problem since then. The battle against weeds is a never ending one and often the costliest agronomic input for successful crop production. Weeds are most under estimated crop pests in tropical agriculture although they cause higher reductions in crop yields than other pests and diseases. Of the total annual loss of agricultural produce from various pests in India, weeds roughly account for 37%, insects for 29%, diseases for 22% and other pests for 12%. Weeds decrease quantity and quality of the produces [food, fibre, oil, forage/ fodder, animal products (meat and milk)] and cause health hazards for humans and animals. Therefore, weed control is very important for a successful crop production.

Introduction

Papaya is a tropical tree fruit crop that cannot tolerate freezing temperatures. It has commercial importance because of its high nutritive and medicinal value. Papaya cultivation had its origin in South Mexico and Costa Rica. Total annual world production is estimated at 6 million tonnes of fruits. India leads the world in papaya production with an annual output of about 3 million tonnes. Other leading producers are Brazil, Mexico, Nigeria, Indonesia, China, Peru, Thailand and Philippines. Papaya fruit are borne on peduncles attached to the main trunk of the papaya tree and are clustered, starting a few feet above the ground and extending up to a foot below the top of the plant adequate water is essential to the uninterrupted growth and production of papaya fruit. There is number of factors which affect quality and quantity of papaya production. Out of insect pest is one of the important factors to reduction of papaya fruit production. List of insect pests of papaya given as below:

Cabbage (Brassica oleracea, ssp. capitata, 2n = 2x = 18, family Brassicaceae = Cruciferae, cross-pollinated due to sporophytic incompatibility) comes under generic name cole crops. It is a rich source of calcium, and vitamins A and C. It is generally consumed as cooked vegetable, boiled or stewed, raw salad, soup and sauerkraut which is cabbage cut into fine slices that undergo lactic acid fermentation in a brine made of its own juice with salt. Sauerkraut was traditionally made at home in Germany and other European countries, but nowadays it is mainly an industrial product.

According to Indian Horticulture Database-2014 (NHB, 2015), global production of cabbage spread over more than 125 countries has been 70.64 million tons from 2.42 million ha area with a productivity of 29.2 tons/ha. Of this total global cabbage production, top ranking China (32.80 million tons from 0.98 million ha) and second ranking India (9.04 million tons from 0.40 million ha) jointly contributed about 59% of the production. Other countries in the descending order of the production were Russian Federation, Japan, South Korea, Ukraine, Indonesia, Poland, Romania and USA. In terms of productivity (tons/ha), South Korea (71.2 t/ha) and Japan (67.6 t/ha) were far ahead than the rest of the countries which were in the range of 20.1 to 42.9 tons/ha.

During 2017-18, also Indian cabbage production was 9.04 million tons from 0.40 million ha (4 lakh ha) area giving a productivity of 22.6 t/ha. Thus in India, cabbage area seems to be stabilized at 4 lakh ha. The top ten cabbage producing states in India are West Bengal, Bihar, Odisha, Assam, MP, Gujarat, Chhattisgarh, Jharkhand, Karnataka and UP (Horticulture Statistics at a Glance-2018, MAFW, 2018).

Theworld fashioned and occupied by three fourth of the water. Fisheries activities are an indispensable part in the life and livelihood of the peoples. Aquaculture is the most important role for the upward economic strengthening and social mobility. Most of the inland fish farmers are poor due to lack of financial resource. Because of the poor production through the inland fish culture, the most of the farmers in Tamilnadu are undertaking composite fish culture technology. Demand for fish is rapidly increasing due to the growing population and awareness about the superiority of fish to other meats. The marine and freshwater sectors growth were 2.5 and 8 per cent respectively (Ayyapan and Diwan, 2004).

Allocation of the water receipt including anticipated within the crop period and its detailed account of expenditure for efficient and profitable farm management is called as water budgeting.

Water budgeting may be for an irrigation system planned by irrigation engineers; may be for a canal or for an area (block) or may be for a farm according to the need and plan by responsible persons who plan the irrigation efficiency.

1. INTRODUCTION

The demand for high quality planting material is steadily increasing due to interest in vegetable gardening. The need of setting up plant nurseries to meet the demands of the people has been felt by small and marginal farmers as well as by gardeners and farm house owners. In order to meet this demand, there is ample scope for introduction of small nurseries which will serve to augment the incomes of needy sections of rural society. Almost all vegetables crops are propagated by seeds, except sweet potatoes, asparagus, garlic, potato etc., which does better if propagated vegetatively. Among the vegetable crops which are propagated by seeds, cucurbits, beans, peas, radish, turnip, carrots and leafy vegetables seeds are sown directly in the fields. Other vegetables like cabbage, cauliflower, tomato, onion, chilli etc. are first sown in nursery beds where seedlings are raised and then transplanted.

P rotected cultivation technology envisages immense promise, especially for high-value crops against various biotic and abiotic stresses. The climatic parameters stress conditions like unusually low and high temperature, humidity, solar radiation, wind velocity comes under abiotic stresses. The present climate change scenario dealing with various biotic and abiotic stress conditions poses serious threat to agricultural production throughout the world. It is estimated that due to one-degree rise in temperature during rabi season, wheat production declines by 4-5 million tonnes in India. Similarly due to prevailing low temperature and frost like conditions, especially in Northern India, several million tonnes of horticultural crops like tomato, brinjal etc. got wasted every year. Protected cultivation technology deals with following types of protected structures :

7.1 Introduction

Garden designing is an important and crucial step as whole aesthetic view of the garden depends upon it. A beautifully designed garden can attract plenty of viewers as well as fauna while a poorly designed garden can destroy the view of the garden as a whole. So, while designing a garden all the basic principles and elements of gardening should be kept in mind.

7.2 Steps in Preparation of Garden Design

Site identification

Generally, the site for garden development is provided by the client itself. So, in this case we should go for site analysis step directly. Site identification is always a choice of client/human. If landscape architect has liberty to identify a land for garden establishment, he should identify the site as per choice of the client, usage and special considerations of the client.

INTRODUCTION

Rubber cultivation in regions extending from 10°N to 10°S latitude is known as the traditional region and the areas other than its natural climatic origin is termed as the non-traditional region. Northeast India comprises majority of the non-traditional areas in India with major climatic constraints like high seasonal rainfall, excessive precipitation and to some extent dry conditions. These areas extending from 22 to 29^°N latitude, holds promise in extending rubber cultivation because of its exceptional climatic make-up and abundant amount of annual precipitation (2000 mm) distributed over a fair period of time.

This perennial crop generally yields latex rubber at the 7th year after planting (with an economic life span of 20 years), although the period (immaturity period) it requires, is higher in the non-traditional region (Rubber Growers Companion, 2006). This immaturity period has also been shown to reduce with water availability in sub-humid climates (Vijayakumar et al. , 1998). Harvest of this crop is by tapping. Tapping is a process of controlled wounding during which thin shavings of bark are removed, thus opening the latex vessels which exude latex. Dry rubber yield is obtained after the latex is coagulated and rolled into sheets (about 500gm) which is then smoked and dried.

Need for systematic mapping and hazard zonation is emphasized in this chapter. Though prevention of natural disaster is not possible, its destruction could be minimized through implementation of effective hazard management system. With this motive, the coastal region between Tangapatnam and Ovari, Tamilnadu State has been classified into various categories of vulnerability based on its response to the 26th December 2004 tsunami. Based on the extent of seawater inundation and coastal geomorphic features, we have assessed the tsunami impact and estimated the behavior of the beaches in case of similar havoc in future. This study had shown that the maximum seawater inundation recorded in the study area is 750m in Colachel and the minimum is 100m in Kadiapatanam, Mandakadu and Vaniakudy areas. Chinnamuttom, Kanyakumari, Manakudy, Pallam and Colachel areas are under high risk.

INTRODUCTION

On 26^th December 2004, tectonic disturbances happened near Sumatra Island with an intensity of 9.3 in the Richter scale wrecked havoc on southwest part of India. In addition to inflicting life and infrastructure loss, the resultant tsunami event had also eroded severely the coastal region and modified topography of beach and shallow coastal regions. It did raise the concern of scientists and emergency planners about the impact of larger earthquake and consequent tsunami should there be any recurrence of such event. Despite becoming aware of tsunami hazard, there has been confusion about areas at risk and areas of safety. This chapter is an attempt to assess the vulnerability of part of Tamilnadu coast based on its geomorphological conditions and the impact of recent tsunami. The hazard maps have been generated and are intended for educational purposes, to improve awareness of tsunami hazards and to encourage responsible emergency planning efforts by illustrating the range of possible tsunami events.

Weed monitoring is conducted to detect significant weed problems, rank them for relative severity and sort them by management type annuals, biennials, perennials, grasses and broadleaves. Weed monitoring provides information to tailor weed management efforts that reduce the impact of the weeds. The primary objective of weed survey and mapping is to accurately identify and delineate land with populations of unwanted plants. These surveys are conducted so that scientists and managers can predict those areas potentially subject to weed invasion; understand the biology of the invasion process and determine means by which weeds spread; develop, implement and evaluate weed management plans; assess the economic impact of weed invasion and increase public awareness, education and weed management efforts. Weed survey information is collected and compiled into maps showing the distribution and severity of infestation. Weed monitoring involves repetitive surveys to track weed populations over time. A standardized system of weed surveying and mapping is necessary to provide consistently reliable information that can be compared from year to year. Further, a standardized system allows weed survey data to be incorporated into a state wide weed survey database for the production of state wide noxious weed maps.

DEFINITION OF ENTREPRENEUR & ENTREPRENEURSHIP

Entrepreneurs: The word ‘Entrepreneur’ is derived from the French verb ‘ENTREPREDRE’, which means ‘to undertake’. The term is used to refer to anyone who undertakes the organizarion and management of an enterprise with independence and risk as well as the opportunity for profit. An Entrepreneur is a person who has a possession of any enterprise or venture and accepts significant accountability for the inherent risk and outcome.

Definitions of Entrepreneurs by Several Social Scientists are as follow

According to J.B. Say: An Entrepreneur is an economic agent, who unites all means of production, such as- Land, labour and capital to produce products.

1. Sample: One or more units selected from a population of units, or a portion of material selected from a larger quantity of material
2. The Standard Operating Procedures (SOPs) should contain full working instructions as well as information on applicability, expected performance, internal quality control (performance verification) requirements and calculation of results. It should also contain information on any hazards arising from the method, from standards or from reagents.
3. Analytical Samples: The quantity of the analytical sample to be used is usually indicated in tests and assays. Unless otherwise specified, the quantity used may deviate by 10% from that stated. All quantitative determinations should be conducted on triplicate test portions and in these cases, the amount actually taken should be accurately weighed or measured and the result of the analysis calculated on this exact quantity. When substances are to be “accurately weighed” in a test or assay, the weighing is to be performed in such manner as to limit the error to ± 0.1% or less. Quantities smaller than 100 mg should be weighed to the nearest 0.1 mg.

There are many types of intellectual property and its type varies from country to country. The most common types are patents, copyrights, trademarks, design and trade secrets. Intellectual property is an intangible creation of the human intellect and this intangible nature of intellectual property faces problems in comparison of traditional property like land or goods. Unlike traditional property, intellectual property is not dividable therefore a number of people can consume an intellectual good without its consumption. In addition, investments in intellectual goods suffer from appropriation problems, for instance Landowners can surround their land with a robust fence and hire armed guards to protect it, but creators of intellectual property cannot do that to stop their first buyer from replicating it and selling it at a lower price.

Introduction

Modern agriculture has been of great help in alleviating hunger from the world, because the world population more than doubled itself during the last half of the 20th century; it increased from 2.5 billion in AD 1950 to 7.1 billion in 2012 (USCB, 2013). It is predicted that the world population will again double itself by the end of the 21st century and will touch the 12 billion mark. Most of this increase in population has been, and will be, in the developing countries in Asia, Africa and South America. India occupies 2.4 percent of the total land area of the world, but supports 16.7 per cent of the world population. Like many other developing countries in the world, population in India is increased from 345 million in 1947 to 1210 million as per the 2011 census with a growth rate of 1.76 during last decade. Therefore, pressure on land has been mounting up at an alarming rate. Population growth coupled with live stock population expansion, urbanization and industrialization are major contributory factors to it. The unscientific and unplanned exploitation of this limited resource takes its toll in terms of degrading the land. A large proportion of the land area shows clear evidence of advanced and continuing degradation seriously affecting the country’s productive resource base (Abrol and Sehgal, 1994). Jammu & Kashmir and  Nagaland  have maximum share of their land (94%) under degradation. This is primarily due to large areas under mountains, cold deserts and other such degraded lands. In the agriculturally prominent states like Uttar Pradesh (63%), Madhya Pradesh (50%) and Karnataka (46%) (Shalander Kumar, 2011) the extent of land degradation is of great concern and posing a big threat to the natural resources, resulting in almost 5 billion tonnes soil and 6 million tones of nutrient loss every year (Singh, 2009).
