INTRODUCTION

Genetic engineering (GE) and genetically modified organisms (GMOs) provide powerful tools for sustainable development in agriculture, healthcare and many other industries. GMOs are those which were genetically engineered in a laboratory by incorporating a small foreign DNA fragment carrying a gene of interest into the native DNA of the organism. The foreign gene is attached with the necessary regulatory elements to help its expression in the new genetic environment. Genetically modified (GM) crops currently account for some 16 percent of the world’s land planted with soybean, maize, cotton and canola. The global demand for food is increasing because of the growing world population and decreasing arable land. At the same time food and agricultural systems have to respond to several changes such as increasing international competition, globalization and rising consumer demands for improved food quality, safety, health enhancement and convenience. Modern biotechnology involving the use of rDNA technology/genetic engineering has emerged as a powerful tool with many potential application for improving the quantity and quality of food supply. Foods derived from genetically modified crops, commonly referred to as genetically modified food and food ingredients have already become available worldwide with aim of enhancing productivity, decreasing the use of certain agricultural chemicals, modifying the inherent properties of crops, improving the nutritional value or even increasing shelf life. Results of DNA modification may not be limited only to the particular characteristics of the replaced gene. It is therefore important to ensure that when these organisms are released into nature they do not harm the environment or human health [EFSA, 2006]. Such concerns have led to broader interests in the theme of risk assessment in the release of GMOs. A cautious approach is necessary to assess environmental risks which may occur due to introduction of recombinant organisms in the natural environment [Johnson et al., 2007].

Introduction

The state of Maharashtra now again reels under the scarcity of water. Geologically, major part of the state is covered by Deccan basaltic flows. This basaltic terrain, as such, has been labelled notorious as far as the availability of groundwater is concerned. Uncertain availability of groundwater in the terrain is due to heterogeneity in the nature of piles of basaltic flows which adversely affects the geohydrological characters of the rocks.

The area understudy is unfortunately, a part of basaltic terrain in which no storage structures like major dams or medium projects have been constructed across the existing rivers. Consequently, the irrigation in the area and domestic needs of the people solely depend on whatever water is available in the existing dug wells. The wells do not suffice the need of the people because the percolation of water in the wells is not adequate in major part.

INTRODUCTION

One of the most dangerous ecological crises being faced by all living organism now-a-days is the pollution of the environment. It is easier to describe pollution rather than to define it. It is presumed that the environment in past was more or less pure. But due to various activities of man such as industrialization, urbanization, agricultural practices etc, composition of the environment gets changed which is called environmental pollution. Any substance that creates pollution is called ‘pollutant’. There are different types of pollution among which pollution caused by toxic level of heavy metal pollutants is called heavy metal pollution.

Heavy metal pollution is a problematic field of research and is gaining immense importance now-a-days. We have 104 elements in the periodic classification of which 80 are metals. According to Passow et al. (1961), heavy metals are those having densities more than five (5 g cc^-1) and atomic weight twenty three. The term ‘heavy metal’ is imprecise but is widely used although others such as ‘toxic metal’, ‘trace element’ are possible alternatives. Sources of these heavy metals are varying; some of these are encountered in water, air effluent, solid waste and sewage. They are emitted out from various sources e.g. waste water from electroplating industry (Cr, Ni), air emission from fluorescent lamps (Cd, Be), paint pigment waste (Pb, Cr), auto-exhaust emissions (Pb, Te) etc.

4.1 Introduction

There is no widely accepted methodology for evaluation of IPM programmes. It would be fair to say that commonly accepted methodology for evaluation of the IPM programmes is still under development. Three international workshops supported by the Global IPM Facility were held to discuss and review progress in the development of methodologies and guidelines for the evaluation of IPM, particularly of those programmes/projects using the FFS approach (van den Berg and Jiggins, 2007). The need to combine economic and social science approaches was identified by the participants as a major challenge (Waibel et al., 1999). The recommendations of these workshops are:

“Firstly, the methods of impact assessment and evaluation presented by experts from different fields revealed that despite for the many definitions’ about IPM, there was broad consensus that IPM is about avoiding pesticides dependence and about achieving a socially defined level of pesticide use even though there are many types of IPM intervention. They range from ordinary farmer training to sophisticated ‘Farmer Field School’ approaches. Effective communicated research results that challenge existing paradigms and case studies that draw the attention of politicians and civil society can be subsumed under IPM intervention.

Secondly, need for a document that outlines good practices for IPM evaluation is urgent, because of the diversity of IPM intervention that already exist and that can be further expected. Virtually all groups involved in crop protection, including the chemical companies, label their own concept of IPM as it is a free good that can be taken, reproduced and modified by anyone. Hence, IPM can only be measured by its results and no longer by its inputs.

Thirdly, the different groups who participated in the workshop advocated different approaches to evaluation. There were those who see cost-benefit analysis (CAB) as the major tool of evaluation and wanted to refine this tool by adding economic evaluation of environmental impacts and by applying contingent valuation methods and willingness to pay concepts. Others believe that evaluation should not be a checking procedure but should be designed in the spirit of a joint learning experience. Thus, there was a difference of opinion among the economists on the one hand and anthropologists’ and extension specialists on the other hand. But, lastly, it was concluded that there is a need to set standards which must be met if CBA is going to provide the information that facilitates decision-making.

Introduction

Technological advances of the past two decades have profoundly reshaped and enhanced all aspects of medical research and practice. Concepts, methodologies, tools, and applications of medical informatics with the latest technique and approaches are essential for every one pursuing in the medical IT field. Improvements in healthcare delivery in recent years are rooted in the continued industry-wide investment in information technology and the expanding role of medical informatics. The main goal of this chapter is to collate and provide innovative and creative ideas so far published on healthcare in one article for use by the researchers, practitioners and other related with health care system for improving communication environments in health and to explore all new technologies in medical informatics and health care delivery systems.

Medical Informatics can be defined as a discipline concerned with all aspects of understanding and promoting the effective organization, analysis, management, and use of information in health care (American Medical Informatics Association, 2007). In recent years, medical informatics has become a well-recognized branch of medicine.

Introduction
Forecasting of future weather conditions are based upon the collection and analysis of meteorological observations. With the help of advanced computing system and satellite data, the accuracy of weather forecasting is improving day by day. Weather forecasts may be classified according to the space and time scale of the predicted phenomena. With advanced technology, the spatial resolution of accurate forecast is enhanced and India Meteorological Department (IMD) has started to issue the Block-level forecast. The meteorological phenomenon can be distinguished among three classes of phenomena with a scale that is larger than the turbulent microscale: the mesoscale, synoptic scale, and planetary scale (Geer et al., 2018). Considering the variability of agro-climatic condition of India, the micro-level weather based agro-advisory has great importance to enhance the farm income. IMD has initiated the Block-level Agromet Advisory Services (AAS) in collaboration with Indian Council of Agricultural Research through establishment of District Agromet Units (DAMUs) at various Krishi Vigyan Kendra’s (KVK). Improvisation of the existing District-level Agromet Advisory Services (AAS) and starting of Block-level services are the basic objectives of DAMU. The District Agromet Units will act as nodal centre to prepare and disseminate the crop and locationspecific AAS to farmers at block level. Apart from this, the micro-level Agromet Advisory Service was implemented at NICRA (National Innovation on Climate Resilient Agriculture) villages through a network project of Indian  Council of Agricultural Research (Banerjee et al, 2018; Chakraborty et al., 2018). As a part of the nation-wide program, the feasibility of village level agromet advisory has been assessed. Thus, the importance of micro-level  agromet advisory and advisory on extreme weather events are discussed in this chapter.

Over the past few decades, the fields of science and engineering have been seeking to develop new and improved types of energy technologies that havethe capability of improvinglifeall over the world. In order to make the next leap forward from the current generation of technology, scientists and engineers have been developing Energy Applications of Nanotechnology. Nanotechnology, a new field in science, is any technology that contains components smaller than 100 nanometers. For scale, a single virus particle is about 100 nanometers in width.

An important subfield of nanotechnology related to energy is nanofabrication. Nanofabrication is the process of designing and creating devices on the nanoscale. Creating devices smaller than 100 nanometers opens many doors for the development of new ways to capture, store, and transfer energy. The inherent level of control that nanofabrication could give scientists and engineers would be critical in providing the capability of solving many of the problems that the world is facing today related to the current generation of energy technologies.

People in the fields of science and engineering have already begun developing ways of utilizing nanotechnology for the development of consumer products. Benefits already observed from the design of these products are an increased efficiency of lighting and heating, increased electrical storage capacity, and a decrease in the amount of pollution from the use of energy. Benefits such as these make the investment of capital in the research and development of nanotechnology a top priority.

SYNOPSIS

After the break-up of the Soviet Union in 1992, the countries of Central Asia and the Caucasus (CAC) began making the transition from controlled to market economies. All of the countries have programs for economic and social development as well as food security. Over the last decade, the regional population increased 11%, from 72 million in 2002 to 79 million in 2012. Agricultural production has increased throughout the region. For example, vegetable production per decade has nearly doubled due to an increase in the area of the crops grown and to increased yields, and was more than 19 million t in 2011.

INTRODUCTION

Inspite of recent technological developments which have helped to increase agricultural production in many countries, growth of plants and animals continue to depend to a large extent on the weather conditions. Each plant has its own climatic requirements for growth and development and any large scale deviation from it exert negative influence.

Growth of plants is most sensitive to temperature just above a threshold value and near the maximum value, where growth normally stops. Therefore, periods of extreme temperature i. e. low temperatures below the threshold value and high temperatures above the maxima are hazardous to plant development and growth. Extreme temperature conditions during cold spells cause stress and frost; high temperatures lead to heat stress, and both affect agricultural production. Snow and ice storms in late spring or early autumn are very hazardous to many temperate crops.

Similarly extremes of moisture conditions namely dry desiccating winds, drought episodes and low moisture conditions as well as very humid atmospheric conditions including wet spells tend to affect agriculture. High soil moisture situations of water logging and flooding associated with heavy rainfall and tropical storms have adverse effect on plant growth and development since they influence the rate of transpiration, leaf area expansion and ultimately plant productivity. Drastic changes in rainfall variability can have very significant impact, particularly in climatically marginal zones such as arid, semi-arid and sub-humid areas where incidence of widespread drought is frequent. Dry desiccating and strong winds reduce agricultural production as a result of very high evapotranspiration rates. It also causes mechanical damage to plant with weak stems by lodging such as the sugarcane and the banana.

1. Introduction

The Indian government’s New Education policy (NEP 2020) is apositive improvement in this covid-19 scourge. The main NEP for India happened in 1968, trailed by NEPs in 1986 and 2020 under Narendra Modi. India passed the NEP 2020 on July 29, 2020. It tries to reform education and make the countrymoretaught. K Kasturirangan, the previousheadofISRO, led- the NEP 2020 arrangement council. The decision Government of India vowed to modernise Indian schooling in it selection pronouncement (Saha Mushkan, 2020). Educationassumes a fundamental part in building a country; it chooses the nation’s future and its kin’s fate. The effect will be sturdy concerning the development and advancement of the stateandsubject. In this day and age, schooling is urgent. Pre-freedom and post-autonomy periods show the extension and progress Indian Government. It will alter the way India studies; this is the third correction to the instruction strategy. National education policy 2020 plans changes for all gatherings (Kalyani Pawan, 2020).

Abstract

During the past five decades, the role of nitrogen (N) fertilizer in augmenting foodgrain production has widely been recognized the world over. In Indian soils, N deficiency is recognized as a universal problem and its consumption has increased by more than 300 times during the last 60 years.

Introduction

Sheep and goats have a vital economic importance in India, inhabitant in semi-arid region and mostly rose under harsh environmental conditions (high ambient temperature, scarcity of feed and water). The arid and semi-arid regions of India are drought prone due to low and uneven rainfall.  The vegetation of arid and semi-arid tract is more acute during summer when the quality of the pastures becomes vulnerable which in turn decreases the body condition score of animals and reproductive efficiency is being compromised (Maurya et al. 2009a & 2010).  The small ruminants are widely distributed in comparison of other domesticated species. These species of livestock is also a source of employment for marginal and land-less farmers particularly in the arid and semi-arid region of India. Most of the Indian farmers have limited resources and small ruminants production offers an opportunity to alleviate financial conditions and improve living standards.

Rice is a staple food for millions of people in the world, particularly in developing countries like India. The demand for rice is growing with ever increasing population. In India more than 70 per cent of the ground and surface water is being used for Agriculture and out of this 70 per cent is allocated to rice cultivation. Each kg of rice produced with irrigation requires 3000- 5000 litres of water (Anonymous, 2011). The demand of rice in India is increasing with increase in population and is expected to be 140 m.t. by 2025 (Pandey et al., 2008).

Background and Technology Intervention

To increase the water use efficiency coupling piped network and micro irrigation, Department of Agricultural Engineering along with the Tamil Nadu Government introduced a project on “Water conveyance works of modernization of on-farm irrigation network in 5(R) and 7(R) sluices Parambikulam Aliyar Project (PAP)” covering a total area of 109.86 acres in both the sluices.

Significance of this project is to improve the water use efficiency in canal command areas where the farmers were unable to cultivate annual / long term crop due to alternate supply of water in each zone. PAP command area has 4 zones and each zone receives water once in 135 days in a 2 year span through open channel leading farmers to adopt flood irrigation.

Introduction

One of the triumphs of modern agriculture is the increase achieved in the productiveness of land, measured by yield of crops per hectare or per acre. This has enabled the earth to support a much greater population than would have been possible in past centuries. The increased productivity of the land is a result of scientific and technological progress in plant breeding, in control of pests and weeds, in irrigation and in fertilizers to supplement natural reserves of plant foods. But this progress makes it more difficult to fulfill one specific requirement of many crops: pollination. Pollination of flowers is an essential step in the sexual reproduction of angiosperms. Most angiosperm species rely on insects or other animals, rather than wind, for transfer of pollen among individual plants. The pollinators in turn benefit by obtaining floral resources such as nectar or pollen. Pollination is not only mutually beneficial to the interacting plants and animals, but also serves humanity directly through the yield of many crops, and indirectly by contributing to the healthy functioning of unmanaged terrestrial ecosystems (Costanza et al.,1997; Nabhan and Buchmann, 1997; Klein et al., 2007; Abrol, 2007 and 2008).

Introduction

The integrated nature and high diversity of the soil health system may contribute a significant degree of resilience under conditions of disturbance, particularly at lower (largely microbial) trophic levels. Nonetheless, the conversion of natural vegetation to agricultural land results in major changes in both physical organization and community structure in the soil, including species loss and changes in dominance among the surviving biota. This then becomes the resource with which agriculture must work and any targets should realistically be set in relation to the potential equilibria in agricultural systems rather than the natural systems from which they are derived, as has sometimes been advocated. More importantly, it is clear that subsequent agricultural practices may also impair soil health through significant impacts on the composition and structure of the soil biological community and consequently on soil-based ecosystem functions and services. Damage to ecosystem functions can arise both owing to an inadequate supply of resources (carbon, energy, nutrients or water) and through the impact of intensive substitutive practices such as continuous mechanical tillage, the use of pesticides and excessive amounts of fertilizers. These interventions may also impact on soil functions by destroying or changing the habitat of the soil organisms and their capacity to repair it.

Introduction

With the introduction of chemical pesticides in India during 1947 when 250 tonnes of DDT was imported for Malaria eradication programme, there is a steady increase in consumption and at present about 25 per cent of the cropped area is covered by pesticides. Their use has helped in increasing the productivity over the years. The consumption pattern of different groups of insecticides has indicated the same trend. The Indian pesticide industry with 85,000 MT of production in is ranked second in Asia (behind China) and twelfth globally. The Indian pesticides industry is dominated by insecticides where herbicides and fungicides are the key segments globally. Among the pesticides, insecticides account for 57 per cent, fungicide 28.7 per cent and herbicides 14.0 per cent during the year ending 1997-98. Owing to the ban of highly persistent organochlorine pesticides, there is decrease in the trend. Among the different crops, cotton consumes 44.5 per cent of the pesticide worth of Rs.2462.13 millions, even though it occupies only 5 per cent of the cropped area. Cotton is followed by rice (22.00% of pesticides) and other crops.

Apart from insects, pests and diseases, physiological disorders are one of the major threats to fruit industry which cause financial losses global. Over-all, the problems rise due to unfavorable environmental conditions and improper cultural practices which affect the normal plant growth and development is called as physiological disorders of plant. Ladaniya (2008) stated that the physiological disorder is that it is a function of physiological processes fruit tissue abnormality or failure due to abiotic stress, such as temperature, relative humidity, water stress, chemicals/ nutritional excess and deficiency.

Introduction
Globally, the agricultural sector plays an important role in poverty reduction, food security and promotion of nutritious food (Jones & Ejeta, 2016). Although agricultural crop production is essential, there are challenges associated with plants due to pests and diseases infestation in the value chain of crop production. Plant health problems can be resolved through appropriate diagnosis and identification of plant pests affecting agricultural (Ausher et al., 1996). However, Oerke (2006) reported that 40 per cent of crop yield losses are caused by plant pests and diseases of economic importance. The majority of smallholder farmers are faced with risks associated with pests and diseases in plant production. To address challenges faced by smallholder farmers, plant health clinics are important for plant pests and disease diagnosis. The plant health clinics can be defined as a system in which farmers obtain advisory services on the plant pest problem affecting agricultural crops and provide management control strategy for pest management (Alokit et al., 2014). There are many plant health clinics initiatives within the Indian region that provides plant pests and diseases advisory services to all categories of the farmers (Boa et al., 2016). Many plant clinics in developing countries which are run by international research institutions are more efficient and effective as compared to those not run by the research institutions. This review seeks to investigate and assess the state of global plant clinics with the aim of obtaining the efficient and effective plant health clinic model for South Africa. The knowledge, awareness, availability and accessibility of basic plant healthcare to smallholder farmers for plant pests and diseases diagnosis to ensure early detection, pest management and pest reporting remain a challenge. Furthermore, there is limited literature and research on plant health clinics’ establishment and its importance to smallholder farmers in the Indian developing country.
Background of the Plant Health Clinics
To date, there are about 34 countries operating plant health clinics globally and it is estimated that there are 4,500 plant clinics across the globe Centre for Agriculture and Biosciences International (CABI), 2020; Tambo et al., 2020). These include plant clinics in Africa, South America and Asia respectively (Boa, 2009; CABI 2020). The first plant health clinics were established in 2003 in Bolivia (Bentley et al., 2009; Boa, 2009). In Africa alone, plant clinics were established with the help of CABI to assist smallholders and household to respond effectively and efficiently towards plant pests and diseases. According to Boa et al. (2016), there are two types of plant health clinics in terms of service provisions, namely (1) Fixed structure with appropriate laboratory equipment

Farmer Field School (FFS) is a capacity building method based on adult education principles for group of farmers. FFS is best described as a ‘school without walls’, where farmers learn through observation and experimentation in their own fields. FFS methodology is potential extension approach to enhance farmer’s knowledge which is a basis for adoption of improved practices (Manoj and Vijayaragavan, 2014). In Andhra Pradesh Department of Agriculture initiated FFS programme in the name of Polambadi during 2006.
