1. Introduction

By 2030, sustainable development must be achieved through cross-sector cooperation, creativity and comprehensive initiatives. Aquaculture has contributed to SDGs; however, its contribution depends on the effectiveness of local and international governance (Farmery et al., 2020). Because it includes all aquatic ecosystems, it is one of the global food-producing industries that does so at one of the fastest rates (Mugimba et al., 2021), accounting for approximately half (46%) of the total global fish production (FAO, 2020). Understanding the various environmental, social, and economic aspects of aquaculture offers a more specialized method for handling opportunities and challenges for future development (Troell et al., 2023). Global seafood consumption has risen from 9.0 kg in 1961 to 20.2 kg in 2020, accounting for over 17% of the world's intake of animal proteins (FAO 2022). Indeed, there are considerable regional differences in the production potential and value of the aquaculture sector (Naylor et al., 2021). Over the past 20 years, China, India, Indonesia, Vietnam, Bangladesh, and Egypt have been the major producing countries that have consolidated their share of regional or global production (FAO 2020). Moreover, developing nations account for more than 95% of global aquaculture production, growing at an average annual rate of 6.13 percent (FAO, 2020). As the name aquaculture indicates, it involves farming various aquatic organisms, ranging from the production of unicellular Chlorella algae within indoor bioreactors (Gors et al., 2010) for Atlantic salmon (Salmo salar) production in outdoor floating net cages (FAO, 2019). The aquaculture production of fish is the largest, accounting for over half (53.4 million tonnes) of all farmed aquatic species. Aquatic plants (31.8 million tonnes), mollusks (17.4 million tonnes), crustaceans (8.4 million tonnes), amphibians and reptiles (471,784 tons), and miscellaneous invertebrate animals (422,124 tons) are among the other important aquatic species farmed (Tacon 2019). Although aquaculture is a fast-expanding industry that provides billions of people with food and is a means of subsistence worldwide, several obstacles could prevent this sector's expansion and sustainability on a global scale.

Sustainability is one of the main guiding principles for our modern societies. Water and sustainable development are closely linked since the provision of water is sufficient quantities and of high quality have important impacts on our environment, society and industry as well as the well-being of next generation.

Nowadays, there are several emerging problems and risk that affects the sustainable management of water resources. Pollution diffusion pose major threat. Water resources and demand for water remain unbalanced at various levels. Groundwater abstraction and over exploitation have serious environmental impacts. Reservoirs for water storage, flood control, recreation and energy production remain controversial. Climate change on the other hand is creating lot of impact on both water availability and water demand. These problems have not only physical, chemical, biological and ecological dimensions but encompass also important socio-economic issues such as, regulatory framework for water resources management, methods to balance conflicting human and ecosystem demand, financial sustainability of water management system. This shows the complexity water managers face for sustainable management of water resources and the need to shift from strong traditional, local and regional water resources management approaches to more integrated river basin approaches dealing with uncertainties in environmental conditions, societal development and global change.

Abstract
Sustainable agriculture aims to meet current food needs while ensuring the health of the environment, economy, and society for future generations. The integration of innovations in technology, practices, and management is crucial for achieving this goal. This chapter explores various innovations that are transforming sustainable agriculture, including advancements in precision farming, biotechnology, renewable energy, and integrated pest management. By analyzing case studies and current research, the chapter demonstrates how these innovations contribute to increased productivity, resource efficiency,
and environmental protection. Challenges and opportunities associated with these innovations are also discussed, providing a comprehensive overview of the pathways towards a more sustainable agricultural future.

Dabbling ducks: Duck species that principally feed in shallow water by “tipping up” or dabbling on the surface.
 
Damping off: i) The wilting of young seedlings by certain fungi that cause decay of stem, or roots. The major diseases of germinating seeds are grouped under the single name ‘damping off’. It is caused by a number of separate fungi, mainly species of Pythium, Rhizoctonia and Phytophthora. The disease is expressed either by the failure of seedling to emerge or by the death of the seedling shortly after emergence. Protection from this is to allow the surface of the soil to dry before doing additional watering. Sphagnum moss spread thinly over the soil surface is also effective in reducing damping off. ii) A term used to describe the action of parasitic soil fungi, which cause rotting of seedlings before or soon after germination. This can sometimes be avoided by adding sand to the soil mixture to improve drainage, thus preventing the fungi from multiplying rapidly, or by using fungicides. Eucalypts and pine species are particularly susceptible to damping off.

Introduction

The availability of food depends on the production and distribution while the access to food is determined by an individual’s purchasing power. Thus, the food security in the framework of economic welfare is the situation in which the lowest income strata has a near zero probability of being vulnerable to famine and in terms of calorie it requires a near zero probability of falling below the poverty line (Rentlinger and Selousky, 1978). Therefore, food security concerns every sovereign country, especially the developing and poor nations, owing to its profound implications for their socio-politico-economic stability and which co-exists with international diplomacy. According to 1998 annual report of International Food Policy Research Institute (IFPRI), about 73 million people would be added to the world’s population every year between 19952020 increasing it by 32 percent to reach at 7.5 billion. Much of the population growth is expected to occur in the developing countries mainly in India where the population is expected to increase by 36 percent to touch at 1.27 billion by 2020 and is likely to overtake China by 2035. Therefore, meeting the food and nutrition needs of growing and urbanized population with rising incomes will have profound implications for agricultural production and food security of the country and Himachal Pradesh is no exception.

Introduction

The management of cereal waste has emerged as a critical issue in the quest for sustainable development, particularly given the central role that cereals play in the global food supply. Major cereal crops such as wheat, rice, maize, barley, and oats are foundational to diets around the world, providing essential nutrients and serving as key economic commodities. However, the inefficiencies and losses that occur at various stages of cereal production, from pre-harvest to consumption, represent a significant challenge. These losses not only contribute to food insecurity but also pose severe environmental concerns, including unnecessary greenhouse gas emissions and the squandering of valuable agricultural resources like water and energy. Addressing cereal waste is thus paramount for ensuring both food security and environmental sustainability.

The scope of cereal waste is broad and multifaceted, occurring at several critical junctures within the food supply chain. Pre-harvest losses are often due to pests, diseases, and unpredictable weather conditions that can devastate crops before they are even harvested. Post-harvest losses arise from inadequate storage facilities, improper handling, and inefficient transportation systems, which can lead to significant quantities of cereals being spoiled or lost. During processing, the use of outdated technologies and practices can result in considerable wastage. At the distribution level, logistical inefficiencies further compound the problem, while at the consumption stage, improper storage, over-purchasing, and food spoilage contribute significantly to waste. Each of these stages presents unique challenges and opportunities for reducing waste.

Introduction

The goals and ideas of organic farming and regenerative agriculture are quite similar. Organic farming is a method of cultivating crops that prioritizes ecological sustainability by eschewing the use of artificial chemicals and genetically modified organisms in favor of more traditional practices. Producing residue- free food while also improving soil health, biodiversity, and ecological balance is the primary goal of this method. To restore and improve the health of the soil, ecosystems, and communities involved in agricultural systems, regenerative agriculture goes above and beyond organic farming. The ultimate goal is the development of resilient and sustainable agricultural systems that can deal with the effects of climate change.

Regenerative agriculture and organic farming share a common set of values, including an emphasis on the importance of good soils to successful and sustainable farming. Crop rotation, cover crops, and composting are some of the methods advocated by these people to improve soil fertility, structure, and biological activity. Preservation and promotion of a wide variety of plant and animal life on and around farms is an aim of both organic and regenerative farming practices. Pest and disease management, pollination, and ecosystem stability are all bolstered by biodiversity. Both methods encourage using less or no man- made chemicals, such as those found in pesticides, herbicides, and fertilizers. Organic matter, compost, and biological pest management are just some of the natural inputs that these farmers rely on. Water, energy, and material resource conservation are fundamental to both organic farming and regenerative agriculture. To lessen agriculture’s impact on the environment, they advocate for methods including water management, efficient irrigation systems, and the use of renewable energy. Strong relationships and collaborations between farmers, customers, and local communities are prioritized by these methods. All along the agricultural supply chain, they are committed to fair trade, social equity, and transparency. Farmers may grow healthy, resilient, and sustainable farming systems by applying the holistic concepts of regenerative agriculture to conventional organic farming practices. In addition to strengthening the bond between agriculture and its natural surroundings, these methods also improve soil quality, lessen negative effects on the environment, increase biodiversity, and result in more nutritionally dense food.

1. Introduction

The aquaculture industry is a rapidly expanding domain of food production worldwide. With the exponential growth of the human population, there has been a corresponding rise in the demand for natural resources. Therefore, all technologies aim to maximize food production. The widespread expansion of aquaculture, especially in coastal areas, increases the load of biomass in the culture water and presents enduring ecological hazards. (Piedrahita 2003; Sharifinia et al., 2018, 2019).

The primary challenge confronted by aquaculturists as a result of rapid intensification of the system is the quality of water. Consequently, there has been a surge in eco-friendly management and cultivation practices. Additionally, the development of aquaculture is limited by high land costs and its heavy reliance on fish oil and fish meal (Browdy et al., 2001; De Schryver 2008). Nevertheless, the sector continues to exhibit limited productivity, which is primarily attributed to inadequate quality inputs and substandard culture technologies. With substantial operating and maintenance expenses, the acceptance of recirculating systems among farmers, specifically in developing nations, is limited. Hence, there is a growing requirement for an affordable, environmentally friendly technology that is embraced by farmers and can be widely implemented (Ahmad et al., 2017; Karimanzira et al., 2017). There is growing interest in enclosed aquaculture systems, primarily driven by the biosecurity, environmental, and marketing benefits they offer compared to traditional, semi-intensive, and extensive systems (Ray, 2012).

Human life on the earth has been intertwined with the fabric of crops and livestock for its sustenance, since time immemorial, for food and protection against the vagaries of nature. When agricultural and livestock production systems began to change in the 1950s, from traditional extensive systems to semi-intensive and intensive production systems, diseases of rural farm enterprises became challenging. Especially, the emerging diseases in livestock continued to demand more and more investments for ensuring food safety and security. Despite significant progress made in the recent past in reducing the prevalence of animal diseases, there is still an increasing concern over the losses associated with diseases of economic importance that result in production inefficiency. The scientific foundation for the discipline of animal health economics was laid by Morris (1969) and further steps were taken by Ellis (1972) to economically evaluate the Swine Fever eradication programme in Great Britain using cost-benefit analysis, Martin Hugh-Jones (1975) to specialize in GIS to model diseases and assessed the economic impact on production by infectious diseases, James and Ellis (1978) to use the same tool for FMD control programme, Renkema and Stelwagen (1979) to evaluate the replacement rates in dairy herds, Renkema (1980) to analyze the economic aspects of diseases in animals, Ellis and Putt (1981) to suggest the epidemiological and economic implications of FMD vaccination programme in Kenya, and McInerney (1983) to analyze the economics of animal diseases in dairy cattle, the multidisciplinary field of animal health economics was not amply exploited especially in developing countries to assess the extent of livestock disease losses (Ngategize and Kaneene, 1985).

Introduction
Horticulture crops hold significant importance for their economic, nutritional, environmental, and aesthetic contributions. They contribute to agricultural GDP, create employment opportunities, and provide income for farmers and other stakeholders along the value chain. Horticultural crops often have highvalue market demand, leading to increased profitability for farmers and rural communities. The horticultural crops, including fruits, vegetables, nuts, and medicinal, spices are rich sources of essential nutrients, vitamins, minerals and dietary fiber. They contribute to a balanced and nutritious diet, promoting good
health and preventing various diseases. Consumption of horticultural crops is linked to reduced risks of chronic diseases, including heart disease and certain types of cancer. These crops have environmental benefits. They contribute to biodiversity conservation by providing habitats for various species and supporting beneficial insects and pollinators. Additionally, horticultural practices such as agroforestry, crop diversification, and organic farming methods can enhance soil health, reduce erosion, promote water conservation, and mitigate climate change impacts. Adak and Pandey (2018) emphasised soil management of horticultural crops for attaining food and nutritional security of farm women. Babu et al. (2022) explained scientific interventions for enhancing productivity and profitability of farmers’ engaged in horticultural sector while Gundappa et al. (2016c) recommended management protocols for effective controls of mango hoppers to growers. Even, digital solutions are now-a-days is being tried to improve economic prosperity of fruit growers (Verma and Adak, 2021). Horticulture crops contribute to food security by diversifying thefood supply. They provide an array of options beyond staple crops, ensuring a varied and nutritious diet for individuals and communities.

Description and Distribution
Star Anise is the dried, star-shaped fruit derived from Illicium verum which is an evergreen tree attaining a height of 8-15 meter and a diameter of 25 cm. Leaves are entire, 10 -15 cm long, and 2.5-5.0 cm broad, elliptic to oblanceolate; flowers are solitary, white to red colored, fruits are star-shaped, reddish brown in color, consisting of 6-8 capsules (follicles), arranged in a whorl, radiating from the top of a slender short central stem; each follicle is 12-17 mm long, boat-shaped, hard and wrinkled, containing a seed; seeds are brown, compressed-ovoid, smooth, shiny and brittle. The carpels have a pleasant anise-like odor and an aromatic, refreshing, sweet, anise-like taste; the seeds have the same taste, but, to much lesser extent. It is available, whole, and is not usually ground. The plant is indigenous to tropical and sub tropical East Asia. It is extensively cultivated in a limited area with particular ecological factor, in Kwangsi in south-east China, mainland Tonkin in Indo-China, and is mostly imported from China and Indo-China. No import statistics are, however, available for Star Anise. It is now produced to some extent in Arunachal Pradesh in North- East India.
Area and Production
Star Anise is a recent introduction to India, from China, which is the major producer, supplier and exporter of the crop. No organized commercial-scale cultivation has yet been started in the country, but, it is reported to be gradually picking up. According to the latest report by the Deputy Director of The Spices Board, located in Guwahati, in North-East India, about 12.5 tonnes of Star

Introduction

Ruminants are provided with a microbial ecosystem in the gastro-intestinal tract which helps in the bioconversion of lignocellulosic feeds into volatile fatty acids which are utilized by the animal as a source of energy. This microbial biomass is also helpful in synthesis of microbial protein and B-complex vitamins for the host animals. Any disturbance in the microbial balance may affect the performance of the animal adversely and any improvement in the microbial environment may lead to the improvement in productivity of the animal. A number of chemical feed additive like hormone, antibiotics have been used to improve the performance of the animals. But due to residual left over in the animal products and risk of creating disease, resistance against antibiotics, the use of these chemical feed additives have been discouraged and even banned in some countries. As an alternative microbial feed additive seems to be more natural; as it is not creating any new thing in GIT but it is merely restoring the normal and ideal flora in the digestive tract to its full capacity.

INTRODUCTION

Over the past decades, as concerns about declines in local habitats, species, and livelihoods related to agriculture and allied sectors have increased, the potential contributions of local and traditional knowledge (LTK) to ecosystem research and management have been increasingly recognized (Thornton and Scheer, 2012). North Eastern region is well known as one of the 18 hotspot areas of the world and hence is blessed with rich biodiversity and fish fisheries resources. With more than 90% of population being fish eaters, there is heavy demand of fish but a wide gap exists between supply and demand. The region produces over 0.214 million tonnes of fish annually, with almost 50% coming from aquaculture.

Selye, H (1936), the pioneer in stress physiology, defined stressors as noxious stimuli that increase adrenocorticotropic hormone and clubbed these stimuli under the term stress. Rivier and Rivest (1991) and Chrousos and Gold (1992) defined stress as “a state of disharmony, or threatened homeostasis.” Stress challenges homeostasis, but does not disrupt it, in an adapting organism. McEwen (2000) defined stress as a “real or interpreted threat to physiological or psychological integrity that results in physiological and/or behavioral responses.” The following are the various stressors:

Weeds are the plants, which grow where they are not wanted. Jethro Tull (1731) coined the word weed. Weeds can also be referred to as plants out of place.

Definition

Weeds are unwanted and undesirable plant that interfere with utilization of land and water resources and thus, adversely affect crop production and human welfare.

In organic agriculture weeds are treated as childrens of the soil.

In the world 30,000 species of weeds have been listed, of which nearly 18,000 cause serious damage to agricultural production. Eighteen weeds are considered as the most serious in the world and about twenty six species have been listed as principal weeds in crop fields of India, and are listed in annexure V

9.1 Introduction

The sources and types of chemical pollution to which freshwater systems can be exposed are many and varied. The origins of pollutants entering these systems range from those that are predominantly point sources (i.e., industrial effluents) to those that are mainly diffuse, such as agricultural run-off and acid deposition. Some of these are effectively continuous, whereas others are intermittent or episodic.

Pollutants can also be characterized by their quality: general organic loading, specific organic toxicants, inorganic toxicants, and acids. While most of the sources listed above produce mixtures of these characteristics, particular components are enhanced. Industrial effluents generally are the source of specific toxicants, but might also lead to general organic loading.

Some consideration should also be given to the types of system exposed to these pollutants. Most freshwater systems flow, but some more rapidly than others; that is, lakes and ponds have a slow throughput, the so called lentic systems whereas that for rivers and streams is rapid. Because they flow rapidly, the so-called lotic systems have been used for the transport of materials, such as removing industrial pollutants from factories and organic effluents from sewage works.

A view exists that lotic systems that depend substantially on organic inputs from terrestrial ecosystems as a basis for their economy should have the capacity for self-cleansing of at least organic pollutants. However, this perception has been challenged recently (Royal Commission on Environmental Pollution, 1992). Of course, “still” or so-called lentic waters may also be important repositories of pollutants, and are certainly exposed to diffuse inputs from agricultural land leading to eutrophication.

Thus, the challenge for aquatic ecotoxicology is to develop methods that can not only assess but also estimate the ecological impact of chemicals on a variety of complex ecosystems under diverse and complicated circumstances (e.g., periodic perturbations or steady trickles, and mixtures of varying complexity). The predictive approach is important in risk assessment used in the regulation of chemical pollutants. Assessment, at times referred to as a “retrospective approach,” is used to determine whether particular contaminants have an impact on specified natural ecosystems. This chapter reviews current methods, first predictive and then retrospective approaches, to address such problems. Initially, one must define what is to be measured, for it has relevance to both approaches.

Ecology of a place is influenced by a number of biotic and abiotic factors. An agroecological zone is broadly homogeneous in climatic and edaphic factors, but not necessarily contiguous, where a specific crop exhibits roughly the same biological expression. On the other hand, the characteristics of an agroecological zone influence the crops and cropping patterns of the zone. Thus, there are considerable variations in the types and management practices of agroforestry systems being followed in different agroecological zones.

AGROFORESTRY FOR HUMID AND SUBHUMID TROPICS

Humid and subhumid tropical regions have much variation in biological, social and economic parameters. The characteristics of humid tropics include high mean annual rainfall of more than 1500 mm, dry season of less than four months in a year and mean annual temperature of more than 22° C. Rainfall usually exceeds the evapotranspiration. However, demographic pressure has caused excessive deforestation and overgrazing which developed soil related problems like low soil fertility, low organic matter, high acidity and high rainfall erosivity. The agroforestry practices designed for this region should aim for improved fallows, soil fertility improvement and conservation, food production, etc. Thus, the common agroforestry systems in this zone are taungya, homegardens, alley cropping, plantation-crop combination, windbreaks, silvipastoral systems and various intercropping systems. Shifting cultivation is a common practice in tropics which should be discouraged as it causes environmental degradation and ecological imbalance, soil erosion and soil nutrient loss.

What are Pesticides?

Pesticides are essential tools for controlling harmful and invasive pests in agriculture, forestry, and the landscape. Pesticides are any substances used to prevent, eliminate, repel, attract, or diminish pest organisms. Pesticides that are well-known include insecticides, herbicides, fungicides, and rodenticides. Growth regulators, plant defoliants, surface disinfectants, and several swimming pool chemicals are among the others. Insecticides include pesticides (effective against insects), herbicides (effective against certain plants), rodenticides (effective against rats), bactericides (effective against bacteria), fungicides (effective against fungi) and larvicides (effective against larvae).

Introduction

Agriculture is one of the prime economic sectors which generate enormous amount of waste from numerous agricultural operations and has a major share in the overall economy of India.The world’s human population has increased four times in the last century unaccompanied. This population boom,in part a result of improved agricultural and industrial techniques, places continuous pressure on food production in order to feed the growing numbers. Explosion of human population has directed the need in the rise of agricultural production which eventually hassled to the generation of huge amount of agricultural waste. India is an annual gross crop residue producer of which wheat and paddy residues. Agricultural wastes are as the residues from the growing and processing of raw agricultural products such as fruits, vegetables (vegetables and fruit peels) meat, poultry, dairy products and crops (Cereals crops- rice, wheat, maize, pulses, millets, oilseedsand sugarcane contributed the highest crop residue), cereals husks, legume haulms, sugarcane bagasse. Highest in the state of Uttar Pradesh is a leading state of India for residue generation followed by Punjab Maharashtra and West Bengal. Cereal crops (paddy, wheat, maize, millets) contributes 70% residue. Disposal of paddy residue has turn out to be a huge problem in Indian states, resulting farmers prefer to burn the residues in-situ. Improper management practices like dumping of agricultural waste. Based on the global perspective of resource management, education and awareness in the field of waste management is in huge demand. Awareness programmes on these emerging issues could also improvise the regulation of agricultural waste management and lessen its possible health and environmental risks. Systematic utilization of agricultural waste also helps to improve environmental conditions by reducing pollution caused by disposal of huge agricultural waste. Agricultural waste is composed of organic wastes as animal excreta in the form of slurries and farmyard manures, spent mushroom compost.

Abstract
Understanding genetic diversity is essential for achieving genetic improvement and conservation of grain legumes. These crops serve as important pulses grown and consumed all over the world, especially in Africa, South East Asia and America. Legumes serve as a good source of carbohydrates, oil, fibre and proteins. Grain legumes are a major source of food and nutrition globally. However, it has not been possible to enhance gain legume production to the required level, primarily due to the narrow genetic base of most of the legume crops, coupled with changing climatic conditions. Most grain legumes are lacking in desired plant ideotypes and resistance sources for various biotic and abiotic stresses. The genetic diversity conserved in gene banks globally is a major resource for crop breeding programs, but it
is utilized only marginally. Therefore, in order to broaden the genetic base of grain legume crops and enhance the genetic gains made in improvement programs, conventional approaches and modern scientific tools should be integrated in a phased and carefully judged manner. The first phase should focus on the search for desired traits and the infusion of diversity into the cultivated gene pool through use of landraces and CWRs. The second phase should focus on the utilization of advanced selection tools, such as genomics, high-throughput precision phenotyping, and artificial intelligence, to exploit the hidden potential of the available genetic diversity; and the third phase should involve technologies such as mutational breeding, genome editing, and transgenic technologies to improve, modify any novel or alien traits that are not available in the entire crop gene pool. We presume that enrichment of the genetic diversity of cultivated grain legume gene pools, along with simultaneous improvements in their yield and plant type with the aid of advanced scientific tools, will enhance grain legume crop yields to the required level.
