Technologiocal intervention is essential for improving pulse productivity through introduction of suitable high yielding varieties (Masood Ali and Shiv Kumar 2009). This is only possible through: (i) development of high yielding varieties with multiple resistance/tolerance to major diseases like mung bean yellow mosaic virus (MYMV), powdery mildew (PM) and Cercospora in mung bean and urdbean; (ii) development of varieties having resistance and tolerance to pre-harvest sprouting in mung bean, (iii) development of efficient plant type with high biomass and harvest index, (iv) development of varieties suited for intercropping system, (v) broadening genetic base of developed varieties, (vi) development of 50-55 days varieties of mung bean having 1 tonne/ha productivity and resistance to YMV for summer cultivation, (vii) development of high yielding and early maturity varieties of peas having resistance to powdery mildew, (viii) developing rajmash genotypes resistant to bean common mosaic virus and sclerotia rot, tolerant to high/low temperature and shattering resistance are important ones for increasing production through varieties intervention (AICRP MuLLaRP, http://iipr.res.in/mullarp).

11.1 Agroterrorism

‘Agroterrorism’, also known as ‘agriterrorism and agricultural terrorism’, is a malicious attempt to disrupt or destroy the agricultural industry and/or food supply system of a population through “the malicious use of plant or animal pathogens to cause devastating disease in the agricultural sectors”. It is closely related to the concepts of biological warfare, chemical warfare and entomological warfare, except carried out by non-state parties. It refers to a hostile attack towards an agricultural environment including infrastructures and processes in order to significantly damage national or international political interests.

The terms ‘agroterrorism, agroterror and agrosecurity’, were coined by veterinarian pathologist Corrie Brown and writer Esmond Choueke in September 1999 as a means to spread the importance of this topic.

1.1 Introduction

Since the beginning of humankind, we have thrived as a species due to our unique capabilities. These skills have developed and progressed over the centuries to the point that, in recent decades, we have been able to build machines that can imitate our intelligence, as far as we comprehend it. A novel type of world may lie ahead of us.

Artificial intelligence is the future, and the future is here." - Dave Waters

Artificial intelligence (AI) refers to the replication of human intelligence in computers, which are programmed to think and behave in a manner similar to humans. Literacy, logic, problem-solving, perception, and linguistic appreciation are all manifestations of cognitive abilities. Artificial Intelligence refers to the development of computer systems, computer-controlled robots, or software that are designed to exhibit intelligent behavior similar to that of the human mind. The term artificial intelligence is composed of the word "Artificial," which denotes something created by humans rather than existing naturally, and "Intelligence," which refers to the capacity to gain and utilize knowledge and skills.AI is achieved by the analysis of patterns in the human brain and the evaluation of cognitive processes. The culmination of these studies leads to the creation of sophisticated software and systems with advanced intelligence. The term AI was coined by McCarthy et al. 2006 while working on Dartmouth summer research project in which they proposed that machines have the capability to emulate "every facet of learning or any other characteristic of intelligence."

Protozoa are considered as unicellular eukaryotic organisms and evolved after bacteria and thousands years early to multi-cellular organisms as well as animals. This unicellular eukaryotic organism contains all the organelles or structures like multi-cellular organisms but in single cells. Similar to multicellular, the genetic information of protozoa is also stored in chromosomes. The protozoa differ from bacteria in different manners. The differentiating features of bacteria and protozoa are given in Table 1.
1. General Structures of Protozoa
Protozoa, like other eukaryotic cells, contain a nucleus, endoplasmic reticulum, mitochondria, Golgi apparatus, and lysosomes. Beyond these common organelles, protozoa feature a range of unique structures with specific functions that enable them to operate independently. Protozoan cells can be categorized into two primary components: the cytoplasm and the nucleus.

ABSTRACT

Agroforestry research and development in scientific mode in India started about thirty years ago with few individual scientists working on the aspect. However, concentrated efforts started with the establishment of a network under co-ordinated mode throughout the country in the year 1983. Since then lot of research has been done and recommendations made. The present paper compiles the chronological sequences of the starting of AICRP on AF along with its co-ordinating partners. Suitable perennial species and agroforestry systems recommended for respective agroclimatic zones of the country are also compiled. National seminars and group meeting conducted for popularizing and extending agroforestry to every corner of the country had also been provided.

INTRODUCTION

Agroforestry is an age old practice and was a way of life since the settled agriculture evolved from forest. However, with passage of time the cropping system was converted to monocropping and in the way the benefits of integrating the perennials with annuals were forgotten. In the late 70’s of 20^th century, benefits of integrating perennials in cropping system was again realized and efforts were diverted towards scientifically associating the perennials and annuals. Dr. M.S. Swaminathan an eminent scientist while addressing first agroforestry seminar at Imphal in 1979 stated that agroforestry lies the key solution of some of the problems of forestry “what is now important is to give a scientific context and better planning like a good architect who can plan the use of space more efficiently”. This seminar was a spark in the history of scientific agroforestry in India. Taking into account the vide variation in edaphic and climatic factors in India along with the perennial nature of the systems, it was felt that working in isolation would not yield fruitful results and therefore, an association of scientist and institutes of different agroclimatic regions in form of a network was felt imperative and a viable wayout and hence the birth of AICRP on Agroforestry. All India Co-ordinated Research Project on Agroforestry (AICRPAF) was initiated vide ICAR letter number 21(1)/80-SW & DF dated 7^th February, 1983 at 20 centers of which 12 centers were located in State Agricultural Universities and eight at the ICAR institutes. Later on more co-ordinating centers were added and at present there are 37 AICRPAF co-ordinating centers with 10 centers in ICAR institutes and 27 centers located in State Agriculture Universities covering all the major agroecological zones of the country. The coordinating unit of the project was initially located at ICAR, Krishi Bhawan, New Delhi, which was shifted to National Research Center for Agroforestry, Jhansi w.e.f. 1^st April, 1997 under the administrative control of Director, NRCAF.

Introduction

Aquaculture and Fisheries remain important sources of food, nutrition, income, and livelihoods for hundreds of millions of people around the world including in India. Total fisheries and aquaculture production reached a record of 214 million tonnes in 2020, comprising 178 million tonnes of aquatic animals and 36 million tonnes of algae (FAO 2022). Global aquaculture production continued to grow amid the worldwide spread of the COVID-19 pandemic. Global aquaculture production consisted of; 87.5 million tonnes of aquatic animals predominantly used as food for human consumption; 35.1 million tonnes of seaweeds and other micro-algae for both food and non-food uses. Global consumption of aquatic foods has increased significantly. In 2019, global aquatic food consumption was estimated at 158 million tonnes and consumption increased at an average annual rate of 3.0 percent from 1961, compared with a population growth rate of 1.6 percent. In India, the total fish production during the year 20-21 is estimated at 14.73 Million Metric Tonnes (MMT) with a contribution of 11.25 MMT from the inland sector and 3.48 MMT from the marine sector. The fisheries sector contributes about 1.24% to the gross value added (GVA) and 7.28% to the agricultural GVA. In India, the changing consumer preferences, advancements in technology and income growth are the real drivers that augur well for further expansion and demand of food from aquatic origin. Against this backdrop, this sector is poised for unprecedented growth and opening various avenues of entrepreneurship.

Abstract

Leafy vegetables have largely been portrayed as fulfilling an important nutritional supplement in local people’s diets, as a safety net function to rural households during periods when agricultural production is low and as a food supplement for the poverty stricken. In this paper we present evidence to show that the consumption of wild leafy vegetables (pot-herbs) represents more then just an important source of nutrition and/or a safety net function for poor households, but that they also fulfil an important cultural function for both poor and wealthy Xhosa speaking people in the Eastern Cape, South Africa. We show that the consumption of food needs to be studied as a bio-cultural phenomenon which includes both nutritional and anthropological understanding.

Introduction

Large scale exploitation of groundwater using modern deep well boring technology and powerful pumps is the order of the day in India and elsewhere. Increase in agriculture area and year around cultivation of water intensive crops, frequently failing monsoons (Fig.5.1) all have led to drying up of surface water and increased dependence on groundwater.

Thus, given the scenario of over exploitation of the available groundwater, it is essential that proper storage and management of available groundwater resources be identified.

Introduction

Increasing knowledge regarding the impact of diet on human health along with state-of-the-art technologies has led to significant nutritional discoveries, product innovations, and mass production on an unprecedented scale. In particular, naturally occurring bioactive extracts or single compounds thereof, that are believed to benefit human health, have spawned an important and dynamic new area of research resulting in substantial advances in nutritional knowledge. There is also growing awareness that dietary source and form of food may affect overall health. Suitably, the role of food as an agent for improving health has been recognized, initiating the development of new classes of food, known as functional foods (Honkanen 2009).

The concept of functional foods is to improve the general conditions of the body and decrease the risk of illness and disease. That is to say, bioactive compounds present as natural constituents or as fortificants in food having the potential to provide health benefits beyond the basic nutritional value of the product. Marine-derived nutrients and other marine bioactive components have excellent potential as functional food ingredients as they possess advantageous physiological effects, with medicinal characteristics and added health benefits such as anticancer or anti-inflammatory activity.

The marine world, due to its phenomenal biodiversity, is a rich natural resource of many biologically active compounds such as polyunsaturated fatty acids (PUFAs), sterols, proteins, polysaccharides, antioxidants and pigments. Many marine organisms live in complex habitats exposed to extreme conditions and, in adapting to new environmental surroundings, they produce a wide variety of secondary (biologically active) metabolites which cannot be found in other organisms. Moreover, considering its great taxonomic diversity, investigations related to the search of new bioactive compounds from the marine environment can be seen as an almost unlimited field.

Infectious diseases are the result of a complex interaction between the host and the microbes. Evasions of protective immunity by the parasites critically determine the survival and pathogenicity of the microbes. The invasion of the body by harmful microorganisms is called infection.

Nanotechnology has been successfully applied in various fields such as agriculture, biochemistry and medicine. However, its application in food systems has been new and is yet to be scrutinised. It offers a range of physical and chemical benefits that can be employed in production, development, fabrication, packaging, storage and food distribution systems. These novel nanomaterials such as nanocapsules, nanocomposites, nanoemulsions, nanoencapsulation, nano packaging, nanotubes and nanosensors have been used to improve food quality with better shelf life. However, there is concern about the safety of these nanomaterials, especially because of partial knowledge about the effects of these materials on human health.

Gardens have been considered important, sacred from ancient time and the styles developed being inspired form its surroundings. Thus the influences of climate, general landform, religion, spiritual vision, culture, nation, prevailing political conditions, social factors, architectural styles, etc have influenced in developing specific garden style in a particular region. These styles developed slowly over hundreds of years and remained insulated and remained intact till the travelling approach between different countries got well established. Later as the mobility between different countries became widespread, these style forms became intermingled and refined even to new forms. This resulted into the development of Japanese garden style or the arts of ‘bonsai’ making which had its origin in China, or the creation of west coast American garden that originated from the Bauhaus and modern movement that stated life in Germany, the mughal garden style in India based on Persian style from Iran etc.

Basically, the different garden styles can be classified into formal, informal, intermediate and wild garden styles. Aristotle, the father of mathematics and Pythagorus, the father of geometry and disciple of Aristotle, strongly influenced the geometry, mathematics and calculative features of formal garden style. While informal garden style have evolved from the eastern vision of thoughts, originated with Laotsu and Confucious contemplation (preaching) that manifested gardens to express peaceful and compassionate atmosphere influencing meditation, silence and internal harmony.

Introduction

Climate change and climate variability have become a reality. Recent climate changes have widespread impacts on human and natural systems including agriculture. According to Inter-Governmental Panel on Climate Change (IPCC, 2007), climate change refers to a statistically significant variation in either the mean state of the climate or in its variability, persisting for an extended period (typically decades or longer). For example, it could show up as a change in climate normal (expected average values for temperature and precipitation) for a given place and time of year, from one decade to the next. Climate change may be due to natural internal processes or external forcing, or to persistent anthropogenic changes in the composition of the atmosphere or in land use. In last 130 years (1880-2012), the global averaged combined land and ocean surface temperature has increased by 0.85 [0.65 to 1.06] °C (IPCC, 2014). This increase in temperature is disturbing global climate system as a result we are observing climate change on entire continent. IPCC has projected the temperature increase between 1.1 °C and 6.4 °C by the end of the 21st Century (IPCC, 2007).

Introduction

Wells are vertical shafts excavated or holes drilled in earth to the level of water table for extraction. Digging of wells is an age old practice. Shallow dug wells supported communities in the past. Well water is drawn to the ground manually or mechanically using variety of containers made of metal, leather, canvass and wood or a combination of them. Draught animals or electrical power are used to draw water for irrigation.

Water table (Fig.6.1) wells extend below the groundwater table and extract free water. Pumping water from these wells lowers the water level. The well first gains water from the water bearing material in its immediate proximity. Subsequently a cone of depression is formed in the immediate vicinity of the well. Water outside the cone of depression but with in the area of influence is diverted to replace the body of groundwater finding its way in to pumping well.

Agroforestry is a collective name for land-use systems and technologies in which woody perennials including trees, shrubs, bamboos etc. are deliberately combined on the same land-management unit with herbaceous crops or animals either in some form of spatial arrangement or temporal sequence. In agroforestry system there are both ecological and economic interactions amongst the different components (Lundgren and Raintree, 1982). The origin of agroforestry practices, i.e. growing trees with food crops and grasses, is believed to have been during Vedic era (Ancient period, 1000 B.C.), the agro-forestry as a science is introduced only recently. Agro-forestry is the science of designing and developing integrated, self-sustainable, land-management systems that involves the introduction and retention of woody components such as trees, shrubs, bamboos, canes and palms along with agricultural crops including pastures or animals, simultaneously or sequentially on the same unit of land and time, to satisfy the ecological as well as socio-economic needs of people. This practice of growing trees and arable crops together on the same piece of land is an age-old practice with the dry land farmers. Agroforestry results in multiple products, increases income, reduces runoff and soil loss, utilizes off-season rainfall and radiation and gives stability to dry land agriculture. Further it makes the future generation farmers to inherit not only the land of their predecessors, but also the wealth of standing biomass of trees.

National Forest Policy (1988) has set a goal that 33% of the country’s geographical area should be under forest and tree cover. Under Tenth Five Year Plan, the Government of India has set a target to increase the country’s forest cover up to 25%. According to the latest report of Forest Survey of India (2013), the forest cover in the country is 697,898 km², constituting 21.23% of its total geographical area. Out of this, dense forest constitutes 12.24 % and open forest 8.99 %. The only solution to achieve these targets is through the practice of agroforestry. Therefore, in the quest of optimising productivity, the multi-tier system came into existence.

Introduction

In recent years, food scientists, nutritionists and health experts have become more inclined towards functional food components present in various food sources due to their positive influence on health, which is beyond providing the basic nutrition.Nowa days, generalconsumers are also seeking healthier food options because of nutritive food habits and awareness. Therefore, it has triggered the studyof food and deep mining of food components from nutritional and health benefit’s perspective also. Functional food ingredient can be defined as any componentwhich is more than a source of nutrient i.e. provides additional specific health benefits. Milk is well known to exert positive effect on human health, provides nutrition and widely consumed all across the globe in form of either milk or milk products. As per the definition, milk is heterogeneous blend of lacteal secretion which contains various elements that displays wide range of chemical and functional activities. It has been more than a source nutrition and supplement to different age groups either neonates, youngsters or grown up peoples (Park, 2009). It is one of the basicelements of many diets either in its native form or fermented form which every class of people can afford and had evolved as one of the important nourishment sources. Milk in its native form contains fewer bioactive components while fermentation process produces numerous secondary metabolites which possess various health-beneficial properties (Stanton et al., 2005).

Abstract

Water is very essential nutrient and total of only 3% pure water is present on earth. Some natural, anthropogenic and human activities discharge wastes, containing heavy metals into the different water resources and ultimately destroying the ecosystem. Numbers of methods are used for water purification like conventional (includes physical and chemical) and biological. Conventional methods are expensive, generate large quantities of sludge and inefficient at low concentrations of metal. Biological method includes biosorption and bioaccumulation, are ecofriendly and economic and have advantages over conventional methods. Biosorbent material includes microbial biomass, agro-wastes, and industrial by-products are used to treat heavy metal from liquid samples. Actually these biosorbent have number of functional groups on their surfaces which help in binding of metal from aqueous solution. In this article, biosorption of zinc, arsenic and copper are described through lactic acid bacteria that are not harmful, nonsporulating, fastidious, fermentative and generally regarded as safe. Many of these species are probiotic and producing exopolysaccharides and biofilms. It has great resistance to survive in gut environment and efficiency to biosorb metal from gut. It has some significant characteristics that represent a useful tool for decontamination of food and beverages from heavy metals. Biosorption mechanism and factors behind the process make these strains competent of removing these heavy metals.

Cloud-based software is used for the management of financial and field activities of farms. Prior to computers, farmers maintained data manually by keeping lengthy records on papers. This method was prone to human calculation errors. After the computer boom in the 1980s, it was not long before finance software such as Money Counts came to market. 

Seed bearing plants

Seed-bearing plants are broadly categorized in two major types: the gymnosperms and the angiosperms which are together grouped in Division Spermatophyta in the older system of classification for the plant kingdom. Consequently, seed plants are presently classified into multiple phyla. Still, for the purpose of learning basic concepts, it is convenient to group plants informally as spermatophytes (sperm "seed" + phyte "plant"). The spermatophytes are the most complex and evolutionarily advanced plants. Unlike ferns and bryophytes which reproduce and disperse by unicellular spores, spermatophytes reproduce and disperse by means of multi-cellular seeds which consist a protective seed coat surrounding an embryonic sporophyte and its food supply. This group of seed plants exhibits an alternation of generations in which the sporophyte is dominant. Furthermore, the gametophyte is microscopic and heterosporous with the latter term meaning that these seed plants produce two types of spores: microspores and megaspores that give rise to separate male gametophytes (micro-gametophytes) and female gametophytes (mega-gametophytes) respectively. The megaspore is never released from the sporangium; thus, the female gametophyte develops within the sporangium while being still attached to the sporophyte.
