Food security, defined as the availability, access, and utilization of sufficient, safe, and nutritious food for all people at all times, is a critical global challenge. This article examines the multifaceted issues contributing to food insecurity, including population growth, climate change, economic instability, and geopolitical conflicts. It explores the impact of these factors on food production, distribution, and access, highlighting the interconnectedness of global systems. Furthermore, the article discusses various solutions and strategies to enhance food security, such as sustainable agricultural practices, technological innovations, policy reforms, and international cooperation. Emphasizing a holistic and integrated approach, the article argues that addressing food security requires coordinated efforts across sectors and scales, from local communities to global networks. By fostering resilience, equity, and sustainability in food systems, we can move towards a future where everyone has access to the nourishment they need to lead healthy and productive lives.

SYNOPSIS

There have been conflicting practices, recommendations regarding a healthy diet in human beings. Unscientific food habits are limitation to good health and active life. Because of various social, cultural, religious and economic factors human beings in the same climatic conditions and living situations, have been practicing different food habits leading to many health problems. What to eat, how much to eat and when to eat are not clear with the masses. This paper attempts to throw light on these aspects.

Introduction

Foraminifera or forams for short are the most abundant, diverse and widely distributed Protists in marine realm. They are found in all marine environments, from the inter-tidal to the deepest ocean trenches, and from the tropics to the poles (Todo et al., 2005). In some places, foraminifera are so abundant that the sediment on the bottom is mostly made up of their shells. For example, tourists from all over the world get attracted to the pink sands of Bermuda. These sands get their colour from the shells of Homotrema rubrum which has pink to red-colored shells. Living representatives of foraminifera provide ecological data and their mineralized tests are a geochemical record of palaeoclimatic conditions.

Hydrometeorology forecasting is limited to forecasting of occurrence of rainfall to a greater extent. Although several countries all over the world have developed and established hydrometorological forecasting with focus on occurrence of floods and droughts, still there is very limited success. Floods are associated with occurrence of continuous heavy rainfall due to movement of low-pressure systems like cyclones and depression overflow into rivers, reservoirs and breaching of bunds. In countries like India, the floods occur on the average in 70 lakh hectors of area and the economic loss due to floods and expenditure on relief operations mounting year after year besides loss of life. Foods occur at all of a sudden leaving little time for planning mitigation or rescue operation. Flood forecasting in based on impact assessment of heavy rainfall assessments to identify the exact area that is likely to be affected. It requires more intensive research. Forecasting of droughts is still an area of serious concern. There is need to strengthen regional capabilities to develop forecasting techniques for occurrence of flood and droughts through proper analysis of historical data in conjunction with meteorological forecasts and remote sensing data. Though flood alerts are issued, the identification of exact area and the extent to which flood impacts are not very clear most of the times heavy rainfall warnings are not just sufficient until and unless the vulnerable areas can be clearly specified. The medium range forecasting will be extremely useful for issuing flood alerts.
14.1. Forecasting Droughts
Long range forecasting of seasonal rainfall can indicate the possibility of receiving excess or deficit rainfall over larger regions. In India, there is considerable progress in development of long range forecast of Southwest monsoon rainfall. This forecast also indicating the regions which may get surplus or deficit rainfall and for indifferent parts of a given region as well. However, there is serious dearth of local expertise to further analyse and interpret the long-range forecast for a given area on the basis of local climate data. The advantages of reliable long-range forecast are still unexpected. Almost one fifth of the area in India gets affected by draught most of the years. The drought affects are more severe in arid and semi arid regions. Prediction of occurrence of drought and its intensity, period of occurrence and the areas to be affected by drought is very important. During recent years, there is considerable increase in the occurrence of droughts due to climate change which is attributed mainly to atmospheric pollution. The physics of the pollution is consistent and not the policies support in handling hydrometerological disasters. There are instances where in flood and droughts occurred in the same

This chapter introduces the biological and physiological foundations of forest ecosystems, focusing on the structure, growth, development, adaptation, and survival of trees. It examines tree growth and development, photosynthesis, respiration, water transport, nutrient uptake, and plant responses to environmental stresses. The chapter also explores forest biodiversity, forest–atmosphere interactions, forest ecology, microbiology, entomology, and pathology. Particular attention is given to physiological, morphological, and anatomical responses of woody plants to drought, flooding, temperature extremes, salinity, and other abiotic stresses. These concepts provide a scientific basis for understanding tree health, forest productivity, adaptation, conservation, and sustainable forest management.

Forest microclimate is the climate within a forest in contrast to a nearby open area created by a clearing or pasture. A robust observation is that less sunlight reaches the ground in a forest than in open areas, but this depends on the size of the clearing, the height of trees surrounding the clearing, and the location in the clearing (relative to the edge) where measurements are obtained. Daytime temperature is generally lower in forest than in open areas, with greatest differences during the growing season; but this, too, is subject to edge effects and whether the canopy is sparse or dense. Wind near the ground is less than in exposed areas or above the canopy. Another point is that there are various microclimates within a forest canopy. The environment of the forest overstory differs from that of the understory, and this has important consequences for species conservation and protection from climate change. The forest microclimate has important implications for habitat and biodiversity conservation and may act to buffer forest understory organisms from the severity of climate change. Forest microclimates differ not only in contrast with open land, but also vertically with position in the canopy (Fig. 8.1).

This chapter introduces the principles and practices involved in the collection, processing, evaluation, storage, and management of forest seeds. It examines forest seed biology and variability, seed quality and viability assessment, seed dormancy, and methods used to overcome dormancy. The chapter also addresses seed handling, storage, pest management, certification, and the integration of seed technology with genetic improvement programmes. By connecting seed quality with successful regeneration and tree improvement, the chapter provides a foundation for producing healthy and genetically suitable planting material for forestry and conservation programmes.

13.1. Forms of business organisations

Factors to be given weightage for choice of a suitable form of organization

Type of business - service, trade, manufacturing.

Selection of industry and area of operation.

Scope of operations, volume of business and market size, including its expected growth potential.

Amount of capital funds required – initial capital, working capital.

A single active ingredient often is sold in several different kinds of formulations as follows:

(a) Dry Formulations
1. Granule (G)

Granule is, a ready-to-use, dry mixture of a small amount of active ingredient with inert carriers. Most are made by applying a liquid formulation of the active ingredient to coarse particles (granules) of some porous material such as clay, sand or plant material. Granule particles are much larger than dust particles; will pass through a 4-mesh sieve but not through an 80-mesh sieve (the number of wires per inch). The herbicide is absorbed into the granule, or coats the outside of it, or both. Inert ingredients may be added to make the formulation handle well. The amount of active ingredient usually ranges from 1 to 15 percent.

Major advantage of chemical herbicides over other methods of weed control is its ease of application, which saves the cost of labour for the farmer. Effectiveness of herbicide depends on how long it remains in active form in the plant /soil. The form in which any herbicide is available in the market is known as herbicide formulation. The technical active ingredient (ai.) of the herbicide is converted to a formulations so as to improve easiness of handling, retention on leaf surface, absorption and movement in the plant. Herbicides are available in different formulations.

Introduction
Technology transfer and capacity building are critical to the advancement of agriculture, particularly in ensuring that research findings and innovations reach stakeholders efficiently. The Directorate of Extension (DoE) at Kerala Agricultural University (KAU) is a key player in this process, liaising with state development departments to drive technology dissemination in the agriculture and allied sectors. The DoE collaborates closely with development departments of agri and allied areas in the State, acting as a vital link to ensure that agricultural advancements reach the grassroots level. The Directorate also integrates institutional mechanisms to support this technology transfer. Through a network of Krishi Vigyan Kendras (KVKs) and several institutional mechanisms, the Directorate integrates new agricultural technologies into mainstream practices, focusing on both skill development and sustainable development strategies. It conducts workshops, seminars, and training programs focused on enhancing the skills of extension workers, farmers, and other stakeholders. The focus is not just on disseminating new technologies but also on building long-term capacity through skill development. This ensures that the stakeholders are well-equipped to implement the innovations in a way that promotes efficiency, productivity, and sustainability. In essence, the DoE at KAU is a driving force in modernizing agriculture in Kerala. Through its structured efforts in technology transfer, skill enhancement, and the promotion of sustainable practices, it enables the agricultural sector to keep pace with scientific advancements while ensuring that the benefits are accessible and applicable at the field level.
Initiatives / Interventions of DoE, KAU
The Directorate of Extension is crucial in bridging the gap between agricultural research and field-level application through various innovative initiatives. Key interventions include the popularization of agricultural technologies, primarily through farm-based production programs, Block Level Agricultural Knowledge Centres (BLAKC), and the Mukhamukham (face-to-face) Agro Clinic. The Directorate also focuses on capacity-building programs, entrepreneurship development, and ICT-enabled technology dissemination. Additionally, the Directorate supports vulnerable sections of society, develops Farmer Producer Organizations (FPOs), and implements state-funded development projects, contributing to the holistic growth of Kerala’s agricultural sector.

Introduction 
In order to ensure that future generations can prosper, sustainable development is an all-encompassing strategy that aims to strike a balance between social equity, environmental protection, and economic growth. The inclusion of genderresponsive policies is one of this agenda’s most important but often ignored components. Encouraging inclusive and sustainable development outcomes requires acknowledging and addressing the unique needs and contributions of different genders. Empowering women and other marginalized genders have positive effects on resilience, economic productivity, and environmental stewardship that go beyond local communities. Policies that are gender responsive aim to address systemic disparities by advancing equal opportunities and involvement in decision-making. These policies seek to empower marginalized groups while also utilizing their distinct viewpoints and skills to tackle urgent global issues. Women are important in agriculture and natural resource management, for example, so their input is essential in developing environmental policies that work. Gender considerations can be effectively integrated into development frameworks to produce more comprehensive solutions that lead to sustainable outcomes. In addition, promoting gender parity is not just a question of justice but also a critical component of sustainable development. Greater gender parity is associated with faster economic growth and better social outcomes in nations, according to a wealth of research. Entire communities gain when women have access to economic opportunities, healthcare, and education. In order to achieve sustainable development goals and make sure that no one is left behind, creating gender-responsive policies is therefore not just an ethical duty but also a practical necessity. In conclusion, examining the relationship between gender and sustainable development can help us better understand the many issues our world is currently facing. Gender-responsive policies should be given top priority so that we can help everyone reach their full potential and encourage creativity and resilience. This strategy opens the door for a more sustainable and inclusive future by promoting equitable development and bolstering our group’s capacity to handle social, economic, and environmental issues.

Introduction

The procedure of making or building casting in the sand mould cavity or any other material is known as a foundry. This is the cheapest method of shaping the metal. Foundry exercise offers the technique of creating casting in moulds shaped in both sand or different material. A foundry is a manufacturing plant where castings are created by softening metal, emptying fluid metal into a shape, then, at that point, permitting it to harden. Regardless of whether we have not at any time been to a foundry or even know what one resembles, we are encircled by the metal castings. There is a decent possibility that we are perusing this under 10 feet from one.

Moulding

Foundation architectures provide the technological basis for modern artificial intelligence systems and enable models to generalize across diverse tasks and modalities. This chapter examines the evolution of neural architectures that ultimately led to the dominance of the Transformer in contemporary language and multimodal AI. It begins with early neural networks, convolutional neural networks and recurrent neural networks before introducing attention mechanisms and the Transformer architecture. Particular attention is given to the major components of Transformers, including self-attention, multi-head attention, positional encoding and feedforward layers. Encoder, decoder and encoder–decoder configurations are examined through influential models such as BERT and GPT. The chapter further considers Vision Transformers and CLIP, demonstrating the extension of Transformer principles beyond natural language processing. At the same time, limitations such as computational complexity, memory requirements and long-context processing are discussed. Alternative approaches, including state-space models such as Mamba, efficient attention mechanisms, hierarchical architectures and Mixture-of-Experts models, are also explored as promising directions for scalable, efficient and adaptive AI.

Community mobilization stands as one of the most powerful tools for social transformation and sustainable development. It represents the collective action of communities working together to address their challenges, harness their strengths, and create positive change from within. At its essence, community mobilization embodies the principle that lasting development must emerge from communities themselves rather than being imposed by external forces. This chapter explores the fundamental concepts, historical evolution, and practical aspects of community mobilization, providing a comprehensive foundation for understanding this critical approach to community development that has shaped societies across cultures and continents for millennia.

A. Beejamruit
Beejamrit is an organic solution primarily used in seed treatment to promote better germination, protect against soil-borne diseases, and enhance plant growth. It is part of traditional agricultural practices in India and is commonly used in organic farming. he preparation of Beejamrit involves simple, locally available ingredients like cow dung, cow urine, lime, water, and a handful of
soil (often sourced from under a banyan tree). The process is straightforward: cow dung is soaked in water overnight, and the mixture is later combined with lime, cow urine, and soil to create the final solution. This solution is then used to coat seeds before planting, providing them with a protective layer that boosts germination and shields them from pathogens. Beejamrit is valued for its low cost and quick preparation compared to chemical treatments. It is rich in beneficial microorganisms that help improve soil health and support plant growth.
The preparation of Beejamrit, a traditional organic solution used for seed treatment, is simple and involves locally available ingredients. Here’s the  process:

Bhutan has developed the concept of Gross National Happiness (GNH) as a substitute for Gross Domestic Product (GDP). In this theory, GNH comprises spiritual and cultural values, including love of sport, music, dance and spiritual activities. This is a good departure from measuring happiness purely from the view point of money. I would like to elaborate on four pillars that are necessary to uphold sustainable human happiness.

Ecology

There is an increasing awareness of the need for adopting sustainable lifestyles which will not make a heavy demand on our life-support systems of land, water, biodiversity, forests, oceans and climate. In his book titled World on the Edge.1 Lester Brown has described how we still have time to prevent environmental and economic collapse. Recent calculations on the ecological footprint each one of us is leaving behind shows that our per capita consumption of natural resources is exceeding the biocapacity of our earth. Soon we will need two planets to meet the growing demand for land, water, forests and biodiversity. In this context, we should keep in view what Mahatma Gandhi said long ago: 

Fourth-generation biofuels, also known as advanced liquid biofuels, represent a progression of biofuel production leveraging advanced technologies (Chiaramonti & Maniatis, 2020). They incorporate the concept of “carbon capture and storage (CCS)” at both the feedstock and processing levels. Utilizing non-competitive feedstocks like algal biomass, cellulosic materials, and genetically engineered microorganisms, 4G biofuels ensure renewable and sustainable production without relying on arable land or food crops. The feedstock is designed not only to enhance processing efficiency but also to capture more carbon dioxide as the crop grows. Thermochemical processing methods are coupled with CCS technologies, which direct the generated carbon dioxide into geological formations or storage areas such as depleted oil fields or mineral storage as carbonates (International Renewable Energy Agency [IRENA], 2021). Fourth-generation biofuels have the potential to significantly reduce greenhouse gas (GHG) emissions and can even achieve carbon neutrality or negativity compared to previous generations of biofuels. This concept aligns with the idea of “Bioenergy with Carbon Storage (BECS)” (Demirbas, 2010). These advanced biofuels are currently in the development and experimental stages, encompassing various applications related to technology, processing, and feedstock. The primary feedstock for fourth-generation biofuels production consists of genetically engineered high-yielding biomass with low lignin and cellulose contents, addressing the challenges encountered in second-generation biofuels production. Alternatively, metabolically engineered crop plants with lower lignin, high oil contents facilitate enhanced carbon capture capabilities, and improved cultivation, harvesting, and fermentation processes and can significantly enhance biofuels production (Dutta et al., 2014).

1. Introduction Millets, including foxtail millet (Setaria italica), are gaining popularity as “smart foods” due to their numerous benefits for the planet, consumers, and farmers (Anitha et al., 2021). Foxtail millet, classified as a major millet, belongs to the genus Setaria in the Poaceae family. It has a rich history, with archaeological remains dating back 7400-7935 years in northern China and cultivation in Europe around 4000 years ago (Lu et al., 2009). Foxtail millet is currently cultivated in 26 countries and stands as the secondhighest cultivated millet globally. It is a relatively short plant, growing up to 2-5 feet tall, and demonstrates high resistance to various stresses, both biotic and abiotic(Sharma and Niranjan, 2018). The crop’s short generation cycle of 5-8 weeks from planting to flowering, followed by 8-15 weeks to attain seed maturity, allows for harvesting within 75-90 days after plantation. Foxtail millet produces hundreds of seeds per inflorescence (Li et al., 2020).
