7.1 Introduction

Sustainable agricultural systems must be adopted to increase the food production keeping in view of increase in human population. In tropical countries, insect pests are major challenges to increase food production by causing significant damage in the crop fields and stored grains and their products. Interventions by implementing timely integrated pest management strategies are necessary to reduce the yield losses. Efforts to control insect pests have predominantly relied on the use of broad-spectrum insecticides.  However, indiscriminate and irrational applications of insecticides have created the problems such as insecticide resistance, resurgence, secondary pest outbreak and the presence of residues in food and environment (Ansari et al., 2013). Globally, to reduce the pesticide dependence, various technologies have been developed using different approaches to monitor and maage insect pests which are discussed in this chapter.

A current focus of the research community is to advance our understanding of phytonematode biology in sufficient detail to develop novel management methods. Progress in this aim is held back by a lack of functional genetic tools: forward genetics in the sedentary endoparasites is restricted to the root-knot nematode Meloidogyne hapla, and relies on natural variants as the source of mappable polymorphisms (Olaf Kranse et al, 2021) and reverse genetics is entirely reliant on RNA interference and is limited by the variable penetrance and stability of the effect. Despite these restrictions, meaningful progress recently has been made. There is nevertheless an expectation that the development of functional genetic tools would accelerate progress in understanding the biology of plant-parasitic nematodes, and thereby also indirectly the development of novel control solutions.

The packaging requirements for food products are as varied as the foods themselves, with each category necessitating unique materials and design considerations to ensure product quality, safety, and consumer satisfaction. Packaging serves as the first line of defense against environmental factors like moisture, light, oxygen, and microbial contamination, which can significantly impact food stability and shelf life. The role of packaging extends beyond mere protection; it also contributes to preserving texture, flavor, and nutritional value, making it a crucial factor in the overall success of a food product. Chapter 10 delves into the specialized needs of different food types—such as bread and bakery items, snacks, dairy products, coffee, and carbonated beverages—analyzing the packaging materials, structural designs, and technologies required to maintain product integrity. The food industry faces the complex challenge of balancing protective packaging with considerations for sustainability, consumer convenience, and regulatory compliance. This has led to the evolution of advanced

Introduction

Challenges in agriculture and natural resource management in the past have prompted changes in agricultural education, research, and extension globally. The sustainable development of agriculture in a country largely depends on the effectiveness of its agricultural extension strategies, encompassing approaches, service delivery, methodology, and processes. The desired outcome of agricultural development is farmers’ outcomes, achievable through engagement, learning, and participation in research and extension processes. Agricultural extension played a significant role in the green revolution by providing farming communities with appropriate technologies and optimal cropping practices. This helped countries transition from being food deficit to food exporting (Ratnakar, 2016). Additionally, extension services play a crucial role in expanding knowledge, skills, and attitudes about the management of socio-economic-agricultural practices by understanding the existing techno political ecosystem and exploring a basket of technology alternatives for making informed decisions.

Abstract: This chapter reports variations in organic C, total N and P, mineral N and P, and exchangeable K, Ca and Mg, and microbial biomass C in soils in relation to leaf litter and root biomass (0 to 10, 10 to 20 and 20 to 30cm) at two canopy positions viz. under canopy and between canopy of homegarden trees i.e. coconut palm (Cocos nucifera L.), and clove (Eugenia cariophyllata Thunb) and nutmeg (Myristica fragrans Houtt. Nees) spice trees. It also deals with seasonal variations in pool sizes of mineral N (NH4+-N and NO₃--N), and net N mineralization rate (0-15 cm) in relation to rainfall and temperature under the homegarden trees, and examines how high rainfall (incessant rainfall) influences water filled pore space (WFPS), net nitrification and net ammonification rates, pool sizes of NH4+-N and NO₃--N and microbial biomass C in the soils and conserves nutrients in humid tropical climate. The chapter also describes how high rainfall makes phosphorus available in high regime of iron in the soils; and perennial cover crop like Pueraria separately and together with phosphorus increases soil N mineralization. Organic C, total N, total P, exchangeable NH₄+, NO_3- , exchangeable K, Ca and Mg are higher in the under canopy and between canopy positions of all the homegarden trees than that in open. Rate of mineralization is the highest during the post-wet season and the lowest during the dry season (February to April) under all homegarden trees. High rainfall during the wet season, however, reduces the rate of nitrification under all the trees.

Rainfed agriculture occupies about 1.22 billion hectare (Bha) area worldwide, which is about 82% of total area (1.5 Bha) under agriculture (Yadav et al., 2006) and contributes nearly 58% to the global food basket. It is practiced under a wide variety of agro-climatic, edaphic and socio-economic conditions and globally, rainfed agriculture accounts for more than 95% of farmed land in sub-Saharan Africa, 90% in Latin America, 75% in the Near East and North Africa; 65% in East Asia and 60% in South Asia (Singh et al., 2018). 

6.1. Introduction

The growing human population presents a number of issues, including food scarcity, malnutrition, inadequate natural resources (land and water) for agricultural production, and environmental deterioration (MacDonald, 2010). Today, viable intensification of agri-production systems can fulfill rising food, nutrition and environmental demands (Pretty and Bharucha, 2014). Production of rice (Oryza sativa L.), a vital element of food security, which feeds nearly half of the world's population, occupies 143 million hectares of land (FAOSTAT, 2023), and uses up to 90% of all irrigation water in Asia (Liu et al., 2018). For instance, it has been determined that systems for producing rice are one of the main industries that wastes water resources and greatly increases greenhouse gas emissions (FAO, 2013). Therefore, it is necessary to look for ways to manage the rice production system more effectively. In paddy rice systems, co cultivating aquatic animals (fish, shrimp, crab, shellfish, and ducks) and rice has been suggested as a way to reduce the risks of environmental pollution/ contamination linked with rice production while simultaneously optimizing the use of land and water resources to provide humans with both grains and meat (Hu et al., 2016; Ahmed and Garnett, 2011). Co-culture systems have drawn more interest recently due to their potential to reduce the stresses associated with environmental and food insecurity.

Productivity automation refers to the use of technology, software, and artificial intelligence to perform tasks automatically with minimal human effort. The main goal of productivity automation is to save time, reduce manual work, increase efficiency, and improve the quality of output. In simple words, productivity automation means using machines and digital tools to do work faster and more accurately. Productivity automation is used in many areas such as business operations, communication, data management, marketing, education, and personal productivity. For example, sending automatic emails, scheduling meetings, generating reports, managing tasks, and analyzing data are all examples of productivity automation. The concept of productivity automation is based on the idea that repetitive and routine tasks should be handled by machines so that humans can focus on creative,

(I)  Management of Swine

Since early days, cattle, sheep and goats accompanied human beings where ever they migrated but it is not the same with swine because of its rearing in unhygenic conditions. Some communities started avoiding swine because of the foul smell from pigs and slowly it entered into the religious life of Muslims and Yashdies.

            In China since 4900 BC and in England before 800 BC swine production scripts are found in majority in these two countries and at present these countries are leading in swine production. Swine growth is very much influenced by the method of keeping and rearing them and that is why its managemental practices should always be given high priority.

Reproduction

The female piglet attain maturity in 6-7 months of age and has a weight of 60-80 kgs. Males take more time to attain adolesence. The breedable age of a female is 8-12 months when it has a weight above 100 kgs. Its heat period is for 2-3 days. It may conceive by artificial insemination after 2-3 days of heat. The gestation length is 114 days. Weighing may be done after one month of age. Females generally give birth to 6-10 young ones at a time. If more young ones are born, than there are increased chances of death of the young ones.

1. INTRODUCTION

Organic farming systems can deliver agronomic and environmental benefits both through the structural changes and the tactical daily management of the farming system. The benefits of organic farming systems are relevant both to developing and developed nations which helps for environmental protection, biodiversity enhancement, reduced energy use and CO₂ emissions (Thiyagarajan, et al., 2003). The post Green Revolution era has led to environmental pollution due to excessive use of agrochemicals and fertilizers and thus threatened the fragile ecosystem (Selvaraj et al., 2001). Organic farming conserves soil fertility and curtails soil erosion through implementation of appropriate conservation principles (Thampan, 1995). Organic farming leads to live in harmony with nature.

United Nation experts indicate that organic foods have the good opportunities for developing countries to open a space in the global market. This entails the creation of greater awareness of trade opportunities for organic products as well as of the environmental, economic and social benefits to the public.

Livestock farming is an integral part of Indian agriculture system and vital source of livelihood particularly in the rural areas of the country. This sector has been the primary source of energy for agricultural operations (for land preparation, sowing, pulling bullock carts etc.) and major source of animal protein (mutton, chevon, chicken, pork, beef, eggs etc.) for majority of population. India has been habitate of major draught, milch and dual-purpose breeds of cattle as well as buffaloes. Besides their potential our indigenous as well as crossbred animals are unable to produce maximum output due to unavailability of adequate and nutritious feed and fodder throughout the year. The quantity and quality of forage production is directly proportional to the livestock health, production and productivity. There is colossal gap between demand and supply of good quality nutritious fodder. Besides, the availability of lesser area under cultivated fodder crops, the grazing lands also becoming smaller due to the degradation of the land, urbanization, industrial development and increased area under food production to fulfil the demand of increasing human population. To meet the nutritional requirement of such a huge population of indigenous, crossbreds as well as genetically upgraded animals, proper management and conservation of fodder and grasslands is necessary.

Maize occupies an important position in the world economy, and serves as an important source of food and feed (Gupta et al., 2015a). Together with rice and wheat, it provides at least 30% of the food calories to more than 4.5 billion people in 94 developing countries (Shiferaw et al., 2011). In India, maize is an important cereal too, and is grown on an area of 9.2 million hectares with production of 24.2 million tonnes (www.indiastat.com). The demand for cereals will continue to increase as a consequence of the expanding human population. The world will have around 7.7 billion people by 2020, and it will reach up to 9.3 billion by 2050, and the demand for maize between now and 2050 will double in the developing world (Rosegrant et al., 2009). By 2025, India too would require to double the production (50 million tonnes) of maize grain to meet the domestic demand (Yadav et al., 2016).

Malnutrition caused by inadequate consumption of balanced diet has emerged as one of the alarming problems especially in the under-developed and developing world. Mostly the resource-poor suffer from ‘hidden hunger’, a term often used to describe malnutrition caused due to micronutrient deficiencies in staple food diet (Bouis and Welch, 2010).

An estimated two billion people suffer from micronutrient deficiency, while 795 million people are undernourished (IFPRI, 2016a). Of the 667 million children under the age of five worldwide, 159 million are stunted, while 50 million do not weigh enough for their height (IFPRI, 2016b). An estimated 45% of deaths of children under age five are linked to malnutrition (Black et al., 2013). Malnutrition contributes to global burden of disease, and loss in annual gross domestic product (GDP) in Asia and Africa to extent of 11%. South Asia is home to more than 35% of the world’s poor, and 21.9% of the population of India lives in poverty, and thus vulnerable to various health problems (IFPRI, 2016a). 15.2% of the people in India are undernourished, and more than one third of the world’s underweight malnourished children live in India, posing severe socio-economic loss to the country.

With increasing food production, availability and accessibility the global agro-industrial food system has improved.However, malnutrition, biodiversity loss and climate change are newer challenges. The best solution to this is the utilization of indigenous and traditional crops which will bring a transformative change in the food system. There is a need to look into the development of smallholder producers. The agro-industrial food system has improved the food supply and has made way for significant trade-offs with agro-biodiversity, dietary diversity, environmental sustainability and socio-economic stability mainly amongst the rural poor. Now is the time to mainstream the underutilized indigenous and traditional crops into the food system. This will provide opportunities to develop a sustainable and healthy food system.It will also help towards the societal goals which include employment creation, wellbeing and environmental sustainability.

According to the karyotyping the domestic sheep (Ovis aries) has 54 chromosomes. The following is a brief summary of their chromosome composition:

Autosomes: There are one pair of sex chromosomes, 52 autosomes and three pairs of these autosomes are submetacentric (having a centromere slightly off centre), while the rest are acrocentric (with the centromere near one end).

Sex Chromosomes: The X chromosome is acrocentric and the Y chromosome varies from submetacentric to metacentric.

Important features

• According to the Food and Agriculture Organization Corporate Statistical (FAOSTAT) Database (2019) and database of the United Nations Food and Agriculture Organization, the top three countries by the number of heads of sheep were: China (163.48 million heads), India (74.26 million) and Australia (65.75 million). • India has second largest sheep population in the World.

• Sheep milk is an important product in the Near East and North Africa (9% of total milk production) and sub-Saharan Africa (4%).

• The countries with the most dairy sheep are China, Sudan, Turkey and Algeria (FAO).

• Major sheep milk producers are China, Turkey and Greece.

• More than half of the world’s sheep population is found in developing countries. Sheep are more prevalent than goats in cold climatic conditions. The major produce from Sheep production are milk, meat, skin, fibre and manure. However, most of the small-scale producers in developing countries raise sheep for meat or sale.

Today the world is facing a variety of interrelated problems such as food production, energy use, pollution, unemployment and urbanization, mainly because the developmental strategies contravene the basic philosophy of ecology. The world ecosystem is becoming increasingly more unstable through an ever growing dependence on finite resources of fossil fuels. Food production system in developed countries, both terrestrial agriculture and fisheries are energy intensive and are thus, not entirely suitable for developing countries. An alternative strategy to an increasing reliance on fossil for agriculture development should depend on locally available sources of renewable energy and resources. A significant effect could be made through recycling organic wastes into fish. Organic wastes can be recycled in ecologically sound pond based systems fueled by solar energy. The reuse of wastes would safeguard the environment from pollution and lead to a reduction in diseases of insanitation. Recycling of animal wastes is the cheapest way of protein production by reducing cost of production. Fish farming in Europe, Israel and USA is energy intensive, since more farmers use commercially prepared feed formulations which resulted in cost to feed often exceeding 50% of the total operating costs.

In recycling of waste through fish culture, fish is considered to have a great potential to change raw protein into high energetic edible protein. The rationale behind raising fish on organic manure is that about 72.98% of the nitrogen, 62.87% of phosphorus and 82.92% of potassium in the feed rations fed to animals are recovered in their excreta. In most of the world, cereals and legumes account for most of the proteins and calories consumed, but fish produced cheaply by recycling wastes would provide a low energy way to produce an animal product and diversify the diet. Fish, being the cheap source of animal protein is now widely accepted to meet the persistent and widespread malnutrition in developing countries.

Aquaculture is the fastest growing food production sector in the world with annual growth in excess of 10% over the last two decades. Much of this development has occurred in Asia, which also has the greatest variety of cultured species and systems. Asia is also perceived as the ‘home’ of aquaculture, as aquaculture has a long history in several regions and knowledge of traditional systems and is most widespread.

In India there are many scattered case reports on the use of homeopathic drugs in the treatment of certain ailments in animals with individual claims but these reports suffer from lack of evidence, repeatability, documentation and scientific fervor. During last 2-3 decades some reports on the evaluation of homeopathic medicines in the management of animal diseases have appeared in the literature as well as in professional seminars and conferences in India. The abstract summary of these works are given in this chapter.

Clinical Studies

Clinical Management of Udder Diseases of Riverine Buffaloes With A Homeopathic Complex

J.P. Varshney and Ram Naresh (2004)

An uncontrolled observational study was undertaken to evaluate the effectiveness of a homeopathic complex in the management of clinical udder health problems of riverine buffaloes. Cases of subclinical mastitis were excluded from the study. A total of 102 mastitic quarters (fibrosed – 40, nonfibrosed – 62) and five cases each of blood in milk and udder oedema in lactating buffaloes were treated with a homeopathic complex consisting of Phytolacca 200C, Calcarea fluorica 200C, Silicia 30C, Belladonna 30C, Bryonia 30C, Arnica 30C, Conium 30C and Ipecacuanha 30C. The diagnosis of udder diseases and recovery criterion was based on physical examination of udder and milk and CMT/WST score. Bacteriological analysis and somatic cell count were not performed.Treatment was 80 and 96.72% effective in cases of fibrotic mastitis and non-fibrosed mastitis respectively. Recovery period was 21-42 days (fibrosed) and 4-15 days (non-fibrosed). Udder oedema and blood in milk responded favourably in 2-5 days. Cost of treatment was US$ 0.07 per day. The homeopathic complex medicine may be effective and economical in the management of udder health problems of buffaloes. Definitive conclusions are premature due to the limited number of observations and lack of control group.

Packaging, hardening, storage, and shipping are essential final stages that protect ice cream quality after manufacturing. This chapter explains the role of packaging in protecting products from moisture loss, contamination, physical damage, and environmental exposure. It examines hardening technologies, including rapid-hardening systems, tunnels, spiral systems, and other industrial arrangements. The chapter also discusses bundling, shrink wrapping, palletizing, frozen storage, distribution models, and cold-chain requirements under Indian conditions. Temperature control throughout the distribution system is emphasized because fluctuations can cause recrystallization, texture deterioration, shrinkage, and other defects. The chapter provides practical guidance for maintaining product integrity from filling through storage and final delivery.
