Out of 143 million hectares of net cropped area, about 75% is rainfed which contribute about 45% of food grains. These areas produce 55% rice, 25% wheat, 91% coarse cereals, 75% of pulses, 81% oilseeds and 69% cotton. More than 90% of sorghum, millet, groundnut and pulses is contributed from arid and semi-arid. The term rainfed farming (Dry farming) and dry land farming may be defined as conditions where rainwater is the only source of moisture for survival and growth of crops.

1. Introduction

With the advent of globalization and subsequent economic liberalization, the focus of Indian agriculture is shifting from “subsistence” to “commercial” mode, where farming is viewed as a “business” rather than “life-support” system of poor farmers. Enabling farmers “decision-making” capacity is a primary driver of success in the market-oriented agriculture. This “commercial focus” has brought tremendous changes in the “nature” and “mode” of extension work. On the other hand, extension work organizations in developing countries like India, are being impacted by sharp decline in public sector funding, rapid technological innovations especially in the Information and Communication Technologies (ICTs), and the shift to a knowledge-based workforce. These developments created new opportunities for the extension workers to perform the information dissemination, capacity building and technology application more effectively. 

Jasmine

Jasmine oil and its synthetic substitutes are extensively used in high grade perfumes in the western countries, the main buyers being USA, France, UK, Japan, Holland and Russia. Essential oil production is an export oriented agro industry in Egypt, France, Morocco, Belgium, Germany, Tunisia, Italy, Algeria, China and India. It is also used for perfuming expensive soaps and cosmetics, mouthwashes and dentifrices. 

Jasmine oil is unique and the odour of jasmine cannot be imitated by any known synthetic chemicals. There is hardly any perfume of floral origin which does not contain at least a small quantity of jasmine concrete or absolute. The world production of jasmine concrete is approximately 20 tones/year and India’s production is 2 tones.

This chapter introduces the readers about volcanoes and associated features and hazards. Volcanic disasters are like any other geohazards in causing dangerous impacts. However, volcanic explosions are preceded by many surficial expressions that can be detected through satellite imageries, thermal sensors, change in magnetic and gravity anomalies, disappearances of vegetation, sudden appearances of anomalous water vapor, thermal springs and abnormal behavior of animals. Hence, unlike other geohazards, volcanic hazards could be forecast with fairly accurate time limits that may allow evacuation and precautionary safety measures. While avoidance is the best mitigation measure, proper land use planning, provision of scientifically designed damming and diversion methods could save lives and infrastructure from lava flows. Though, atmospheric contamination by volcanic gases, ash cloud and pyroclastic materials could not be thwarted and controlled and thus they could cause havoc.

INTRODUCTION

The term “Volcano” is derived from the name of Roman mythical God of fire “Vulcan”. A volcano is an opening of different shapes, through which, molten rock and gas get ejected either violently or simply flow over earth’s surface. The molten rock and gaseous materials are drawn from deep inside of crust or mantle of the Earth. Repeated ejection of molten materials through vent, fissures or plate margins forms volcanic mountains on earth’s continental or submarine regions.

Volcanism is a threat not only to the lives and infrastructure, but it also drastically alters landscape, impacts atmospheric quality and renders forests, cities and villages and cultivation lands useless. In addition, volcanic eruptions are capable of causing changes in global atmospheric cycles. For example, the eruptions of El Chicho’n in Mexico in 1982, Laki volcano in Iceland and Asama Volcano in Japan in the year 1783 and Krakatau volcano of Japan in the year 1883 have all impacted global climate and atmorpheric dynamics.

Abstract

This review assesses the nutritional attributes of Amaranth grains and its utilization as food and as formulated foods. Amaranth is a pseudo-cereal and one of the most ancient cultural food plants with excellent source of superior quality protein (rich source of lysine) which is deficient in wheat and other cereals. Amino acid composition of amaranth protein is close to ideal and, as a result, has high food value. Amaranth grain is loaded with phytochemicals including phenolic acids, tannins, anthocyanins, and phytosterols. Amaranth is potentially a good dietary source of the pro-vitamin A carotenoid (f-carotene), antioxidants (nutraceuticals) and canthaxanthin (which has also been reported to be an antitumor agent) and lutein, which is reported to slow down the development of age-related eye diseases. There are also some anti-nutritional factors (Phytic acid, Tannin and Trypsin inhibitor etc.) that may be reduced by certain processing treatments. Several epidemiological studies show Amaranth grains are helpful in reducing several kinds of chronic diseases like cancers, cardiovascular diseases, type II diabetes and various gastrointestinal disorders. Grain amaranth has been tested and recognised by many authorities as a gluten-free foodstuff appropriate for incorporation into the diet for celiac disease patients. Amaranth grain or young leaves could completely or partially substitute common ingredients, so the crop could be potentially exploited as an ingredient in foodformulation in form of flour, flakes, sprouts, grain undergoing fermentation, popping, malting, extrusion cooking, nixtimisation, and special compounds isolation. The interest in this crop is developing due to its several advantageous properties. The nutritionists find that the grain has higher nutritional value than conventional cereals.

Basics of effective oral presentation : Planning , preparing (Introduction, Body and conclusion), Delivery, Body language and Handling anxiety-Strategies for giving oral presentation

Oral presentation means delivering an address to a public audience. It also refers to public speaking and/or speech-making. It is a brief discussion of a defined topic delivered to a public audience in order to impart knowledge or to stimulate discussion. The skill in oral presentation is equally as important as effective writing. Almost every oral presentation contains an introduction, main body and conclusion like a short paper. Though it is a formal speech in nature or vocal performance to an audience, it may occasionally require adequate planning and thorough preparation in using one’s voice, body language and visual aids such as slideshows to present and illustrate the points more effectively and to achieve the desired results.

Body languages such as eye contact, facial expression, posture and gesture plays a significant role in oral presentation process. The proper use of the voice and the ability to adjust it to suit the slightest differences of meaning are also very important in oral presentation. In addition to correct pronunciation, variation in pitch and cadence, free from speech mannerism, fluency in delivery are also very important in oral presentation.

Organic farming is increasingly recognized as a sustainable agricultural practice that prioritizes soil health, ecological balance, and long-term productivity. This article explores the intricate relationship between organic farming and soil health, detailing the principles, practices, benefits, challenges, and future prospects. Key organic farming practices such as crop rotation, cover cropping, composting, green manuring, and reduced tillage play crucial roles in enhancing soil structure, fertility, and biodiversity. While organic farming offers numerous benefits, including improved soil fertility, structure, microbial activity, and water management, it also faces challenges like nutrient management, pest control, soil erosion, and weed management. Through case studies and future perspectives, this article underscores the potential of organic farming to contribute to sustainable agriculture and environmental protection, advocating for continued research, policy support, and education to maximize its benefits.

The progress and prosperity of a nation depends to a large extent on well trained and disciplined youth. The youth of today are the adults of tomorrow and farm families of the future. More than half of the India’s population is below 35 years of age. Majority of these young people live in village where they do not have adequate opportunities for vocational training and formal schooling. This vast youth population has limitless energy and enthusiasm. The proper chanalization of this energy for constructive work can make India one of the most developed and prosperous nations of the world. Youth are the future of India, it is therefore, essential to harness them in an organized manner to build up the backbone of the country. If they are given good training they grow up as individuals-physically, mentally and morally capable of playing their full part as adult members of our welfare society.

Youth, defined as those who belong to the age group of 13-35 in the National Youth policy 2003 of India, is considered to be the most vital segment of the population. Across the globe youth is being treated as an asset for a country’s development and enormous investment is being made to develop the human capital. The challenge of nations like India with ‘Youth Bulge’ in their population is to channelize the energy into positive and creative development process. Youth in the 21st Century aspires for a just global order,  They are looking for democratic process in all spheres of life, whether it is education, employment or decision making.  The issues and concerns of youth are fast changing in tune with the technological innovations.

The Northeast Region (NER) of India consists of Assam, Arunachal Pradesh, Manipur, Meghalaya, Mizoram, Nagaland, Sikkim and Tripura, covering an area of 255168 km2. The area is characterized by rich biodiversity, heavy precipitation and high seismicity. Although the contribution from agricultural sector towards gross domestic product has declined, yet it remains the predominant sector for Indian Economy. Over 75% of the people of NE India directly depend on agriculture for their livelihood. Therefore, better performance of agriculture has a direct and multiplier effect across the economy of the region. Because of climate change the rain fed agriculture is facing a greater risk as it is resource poor and having limited flexibility for adaptation. Under changing scenarios there is increase in demand for fresh water and nutrient requirement, increase in soil erosion and nutrient losses affecting soil health, intensification of pest, disease and weed problems, reduction in nutritional quality and low input use efficiency. Continuous mono-cropping and the associated excessive tillage, inadequate erosion control measures and large scale slash and burn cultivation (Jhum) resulted in significant environmental damage and a non-sustainable crop production system in the region.

Introduction

Humans are able to live and work in almost all the environmental extremes of the planet earth and also in space due to their remarkable physiological adaptability and/or by modification of environment itself. Adequate nutrition plays a key role in adaptation and accordingly nutritional needs vary to a great extent. Nutraceutical, a term combining the words “nutrition” and “pharmaceutical”, is a food or food product that provides health and medical benefits, including the prevention and treatment of disease. Such products may range from isolated nutrients, dietary supplements and specific diets to genetically engineered foods, herbal products, and processed foods such as cereals, soups, and beverages. Nutraceutical is a broad umbrella term used to describe any product derived from food sources that provides extra health benefits in addition to the basic nutritional value found in foods. Products typically claim to prevent chronic diseases, improve health, delay the aging process, and increase life expectancy. Phytochemical profile in important crops such as ber, aonla, pomegranate, date palm, karoda, bael, aloe vera, cactus pear of arid region have been indicated that there is wide variation among primary and secondary metabolites. Thus it has become imperative to look into markers linked to high contents of bioactive compounds rather than size and sweetness of the fruits during exploration and evaluation of the plant germplasm.

1. INTRODUCTION

Vegetables differ widely from field crops in their requirements for land preparation and cultural practices because of their differences in their morphologies, growth habit, and socio-economic values. In preparing land for vegetable production, ecological location, mode of cropping, season, crop disposition and the type of vegetables to be grown are taken into consideration.

Clearing: It is often necessary to remove the vegetation cover when a piece of land is to be used for vegetable production. The land clearing methods may involve removing the remains of previous crops and undergrowth, cutting back the woody shrubs and trees and burning them.

Levelling: When the site has been cleared, uneven land may have to be leveled. This facilitates the process of ploughing, harrowing ridging and layout of the site.

Land preparation and layout depend on

Global climate changing has been a focus for a long time in many fields, the increasing CO₂ concentration in atmosphere was considered as one main driving force for global warming. The increases in greenhouse gasses in the atmosphere contributed to raise concerns over climate change enhanced the role of forests and plantations in the global carbon cycle are growing as a great issue. Carbon dioxide (CO₂) is one of the main greenhouse gases because a huge volume of CO₂ is added to the atmosphere, when compare to all other greenhouse gases and made itself as a primary agent of global warming. It contributed 72 per cent of the total anthropogenic greenhouse gases, causing between 9-26 per cent of the greenhouse effect (Kiehl and Trenberth, 1997). According to the Intergovernmental Panel on Climate Change (IPCC), there has been an unprecedented warming trend during the 20th century. Scientists now have estimated that the average global surface temperature is likely to rise by 1.4 to 5.8°C by the end of the 21^st century (IPCC 2007).

The IPCC estimates that the level of carbon dioxide in today’s atmosphere is 31 per cent higher than it was at the start of the Industrial Revolution about 250 years ago. An atmospheric level of CO₂ has risen from 280 ppm at the pre-industrial to the present level of 375 ppm. Most of the increase has occurred in the second half of the 20^th century. The mitigation of climate change demands, determined commitment of scientists to develop strategies to effectively manage the issues of the changing climate through carbon sequestration. Carbon sequestration is ought to be a promising solution for reducing atmospheric carbon dioxide, an important greenhouse gas.

Women account for 43% of the agricultural labor force in developing countries (FAO, 2011) and produce 50% of the global food production (FAO, 2011). Regional statistics reveal that in Latin America about, 20 percent, in Asia, about 30 to 60 percent, and in Sub-Saharan Africa, 50 to 75 percent of the agricultural labour force is supplied by women (FAO, 2013). Moreover, they invest 10 times more than their male counterpart in the family well being especially education and nutrition of children (Maertens and Verhofstadt, 2013). Despite being the primary contributors for the world food production, their roles are highly underestimated. Considerable gender bias exists in the agricultural sector, both in terms of quantities of assets, agricultural inputs and resources that women
control (Deere et al., 2013). Failure to recognize the roles, differences and inequities [between men and women] poses a serious threat to the effectiveness of the agricultural development agenda

Introduction

Mangroves are commonly characterized as halophytic arboreal plant groups that are found in tropical and subtropical coastal regions (Biswas et al., 2012). As stated by Tomlinson (1986), a genuine mangrove species is characterized by its unwavering commitment to the mangrove ecosystem, its capacity to establish exclusive populations, its possession of distinct morphological and physiological traits that facilitate adaptation to the mangrove habitat, and its typical taxonomic separating from terrestrial counterparts.

17.1 Introduction

In an era where digital technologies permeate every facet of our lives, the discourse surrounding data privacy and security has never been more pertinent. However, within this discourse lies a critical blind spot the intersectionality of gender and technology. As we navigate the complexities of safeguarding personal data and ensuring online security, it is important to recognise and address the differential impacts experienced by individuals based on their gender identities. The combination of gender dynamics with data privacy and security unveils a multifaceted landscape characterised by unique challenges and opportunities. This intersectionality necessitates an examination that goes beyond conventional approaches, requiring a critical lens that acknowledges the diverse experiences and power dynamics at play.

The soil-plant-water relationship is a critical aspect of agricultural science, encompassing the interactions between soil properties, plant health, and water dynamics. This article examines the intricate connections that influence plant growth and crop productivity, highlighting the roles of soil texture, structure, and organic matter in water retention and availability. It explores how plants uptake water through root systems and how transpiration affects water distribution within the soil. The study also addresses the impact of irrigation practices and soil management techniques on optimizing water use efficiency in agricultural systems. Understanding these relationships is essential for developing sustainable farming practices that enhance crop yield while conserving water resources.

Introduction
Dystopian literature has emerged as a powerful genre for exploring societal anxieties, particularly in the context of environmental degradation, social inequity, and unsustainable practices. In recent years, these narratives have become increasingly relevant as global discussions around sustainable development intensify. Dystopian works like The Hunger Games by Collins (2008) and The Road by McCarthy (2006) are not only popular cultural phenomena but also significant texts that offer critical reflections on the consequences of unsustainable practices. As Suzanne Collins writes in The Hunger Games, “Destroying things is much easier than making them,” a sentiment that captures the destructive trajectory of unsustainable practices that both novels explore. This paper aims to examine how dystopian narratives, with a particular focus on The Hunger Games and The Road, contribute to sustainable development discourse. By analyzing the themes of resource depletion, environmental control, and social inequality, this study situates these narratives within eco-critical and dystopian studies frameworks, offering a deeper understanding of how literature shapes perceptions of sustainability. Thus, in this paper, an attempt has been made to explore how dystopian literature reflects concerns about sustainability, encourages critical thinking about the future of the environment and society, and emphasizes the importance of equitable, sustainable practices for survival.
Objectives of the Study
1. To analyze how The Hunger Games and The Road depict environmental degradation, resource scarcity, and social inequality, and their relevance to sustainable development discourse.
2. To explore the role of dystopian literature in raising awareness about the consequences of unsustainable practices, particularly ecological collapse and social stratification.
3. To examine the effectiveness of using eco-criticism and dystopian studies as theoretical frameworks to understand the intersection of literature and sustainability concerns.
4. To investigate how dystopian narratives can influence public perception and policy discussions related to sustainability and ethical environmental stewardship.
5. To assess the potential of dystopian literature as a tool for advocacy in promoting sustainable development and responsible environmental practices.

Citrus fruits are originated in the tropical and sub tropical regions of South East Asia, particularly in India and China. North East India is the native place of many citrus species. Citrus fruit has been cultivated in an ever-widening area since ancient times. Although oranges are the major fruit in the citrus fruits accounting for about 70 per cent of citrus output, the group also includes small citrus fruits (such as tangerines, mandarins, clementines and satsumas), lemons, limes and grapefruits. Citrus fruits are consumed as fresh fruit or utilized for preparing processed citrus products. Approximately one third of total citrus production is utilized for processing. India ranks sixth in the production of citrus fruits in the world. In India, it is primarily grown in Maharashtra, Andhra Pradesh, Punjab, Karnataka, Uttaranchal, Bihar, Orissa, Assam and Gujarat. Citrus fruits have several beneficial health and nutritive properties. They are rich in Vitamin C and folic acid, as well as a good source of fiber. In addition they contain potassium, calcium, folate, thiamine, niacin, vitamin B6, phosphorus, magnesium and copper.

Soil and nutrients are important factors for sustainable crop production in agriculture. Water erosion contributes more than 60% to the area under soil degradation in India. Soil erosion has been a serious threat to sustainable agriculture. However, soil and water conservation measures plays important role in improving the productivity of natural resources. India presently supports 17% of the global population with a geographical area of 329 Mha on merely 2.5% world’s land area and 4% fresh water resources. The net cultivable area in the country is about 140Mha is remaining constant or even squeezing from the pressures of urbanization, industrialization, infrastructure development and to house the ever increasing population. The loss of productive soil is another concern. The loss of fertile top soil by water erosion is estimated to be about 5334 Mt per year with it nearly 8.4 million tonnes (mt) of nutrients was estimated in eroded soil still holds true about in i.e. 2.5 mt nitrogen, 3.3 mt phosphorus and 2.6 mt potassium per hectare is lost due to ill soil and water management practices (Dhruvanarayana and Ram Babu, 1983).
