Introduction 
The transformative potential of digital technologies in reshaping governance and development paradigms is increasingly evident, particularly in rural contexts. In India, where nearly 65% of the population resides in rural areas, the imperative to leverage digital tools for inclusive growth has never been more critical. Rural digital governance refers to the strategic use of information and communication technologies (ICTs) to enhance service delivery, improve livelihoods, and foster participatory development in rural areas. It encompasses various applications from digital health, education, and financial inclusion to precision agriculture, market linkages, and entrepreneurial enablement, each designed to address long-standing structural inequities. Historically, rural regions have been perceived as passive recipients of policy support and welfare interventions. However, with the advent of digital technologies, these areas are increasingly positioned to become both demand drivers through rising incomes and service consumption and supply hubs, contributing to national productivity through digitally enabled livelihoods and enterprises. By enhancing access to essential services, improving the efficiency of traditional sectors such as agriculture and handicrafts, and facilitating diversification into non-farm activities like rural tourism and agri-processing, digital governance catalyzes rural transformation. However, the success of rural digital governance is contingent upon adopting a holistic and contextualized approach. One-size-fits-all digital interventions often fail to address the nuanced realities of rural economies. Effective rural technology deployment requires carefully diagnosing local needs, infrastructural capabilities, and livelihood profiles. In this regard, a participatory approach to technology selection and design grounded in the realities of rural life ensures greater relevance, uptake, and impact. Publicprivate partnerships (PPPs) play a pivotal role in scaling such initiatives, with governments providing scale and legitimacy while private actors contribute innovation, technical know-how, and financial investment.

Setting price is a critical component of successful marketing. Vegetable growers have a greater level of control than most other growers over marketable yields, input costs and price. The closer a grower is to the consumer, the more control over price the grower has. Buyers perceive price to represent value of the product. Underpricing, or pricing too low, gives the perception that the product is inferior, while setting the price too high often drives customers away. Many growers make the mistake of setting the price too low at the beginning of the marketing season when competition is less and demand is strong and then find it difficult to increase price later in the season. Before setting price, gauge the level of competition and the consumer demand for your product. For example, organic produce may have a stronger demand in urban areas, so prices can be set at a higher level. Also, early-season produce, such as tomatoes, has high demand with little competition in most markets, resulting in a higher price range.

The Cartagena Protocol on Biosafety entered into force on 11 September 2003. It is a legally binding international agreement under the United Nations’ Convention on Biological Diversity (CBD).

What is a protocol ?: A protocol is a binding international instrument, separate from, but related to, another treaty. It is a separate instrument, that must be individually negotiated, signed and eventually ratified. It is only binding on States that become parties to it. It thus has its own parties, and creates separate rights and obligations for them, as any other treaty.

The unique characteristic of a protocol is that it is related to a ‘parent’ treaty, through substantive, procedural, and institutional links. Most importantly, a protocol under a specific treaty must comply with the parent treaty’s provisions authorizing and regulating the adoption of protocols under its auspices. 

Type and Potential of Organic Residues

A number of diverse sources of organic materials are available for recycling in agriculture. These are mostly of plant origin and recycled either directly or after having being used as feed or food by animals and humans. In view of high organic content and mineral nutrients in the biomass, these are considered as valuable inputs to improve the soil fertility and crops production. Organic resources are low cost inputs but are valuable based on its potential for nutrients and organic matter content.

Attractive Features of Organic Resources

• Organic matter is the basic resource of several essential plant nutrients.

• It buffers the effects of pH dependent changes on nutrient availability.

• They are generated close to their use.

• They are renewable as they are generated regularly.

• With increasing demand for increasing food production, the potential of organic resources is expected to rise.

• Farmers are familiar with organic resources from time immemorial.

Significant transformation took place in the traditional variety improvement and seed production programmes in the sixties and modernized with initiation of hybrid development programme in maize, sorghum and pearl millet, as well as with the introduction, breeding and release of semi dwarf high yielding varieties of wheat and rice. To support the release of varieties and their quality seed production Indian Parliament enacted Indian Seeds Act in 1966. Subsequently, National Seeds Corporation was launched by Government of India for scientific growth of seed industry in the country. All these developments led to the green revolution and country attained self-sufficiency in food crops.

ABSTRACT

The practice of agroforestry in the hills and mountains of Himachal Pradesh is as old as the hill agriculture itself. Farmers are retaining trees on the farmlands for the multiple benefits they provide. The selection of the trees, their planting pattern and density is chosen in such a way that it had minimum effect on the associated crop. The present paper gives the prevalent agroforestry systems with their components in different agroclimatic zones of Himachal Pradesh along with their management practices. Adoption of landuse practices depends to a large extent on status of the farmer concerned. Paper presents the association between type of farmer and the corresponding agroforestry systems they adopt. Sustainability of agroforestry systems, their role in climate change and social and economic gain of agroforestry systems in hills had also been detailed. A comprehensive list of agroforestry components had also been appended as annexures.

INTRODUCTION

Farmers throughout the Indian Himalayas covering about 16 states partially or fully have nurtured trees on their farms and in the agricultural landscape both for production and protection benefits for millennia. Mountainous region like Himachal Pradesh located in western Himalayan range present wide range of tree growing practices and systems owing to the diverse physiographic and demographic mosaic.

The state is located between 30° 22’ 40” to 33° 12’ 40” N latitude and 75°47’ 55” to 79°4’ 20” E longitude and extends over a geographical area of 55673 km² which is 1.69 per cent of the country’s area and 10.5 per cent of the Himalayan landmass. This land locked state is bordered by Jammu and Kashmir in the north, Punjab and Haryana in the south–west and Uttaranchal in the south–east. In the north–east the state forms the international boundary with the Tibet. Agricultural landscapes are characterized by undulating topography wherein terraced fields are made on medium to steep slopes. Crop fields on sloppy lands are in general 5-10 m wide and 20-30 m long almost conical on both ends and wide in the middle. In valley areas and on lands with gentle to mild slopes (up to 40%) large sloping fields have been developed manually by the farmers where Government has undertaken land consolidation.

Wetland birds serve an important ecosystem function of accelerating the nutrient cycling in the feeding grounds (Morales and Pacheco, 1986) and regulating fish populations (Miranda, 1995). According to Drent and Dann (1980), the availability of food is of primary importance to the birds during migration when, they store energy for winter survival and successful completion of migration. Many migrant shorebirds relay on a few key stopover sites to complete their annual migratory cycle (Myers et al., 1987), which provide a unique combination of food resources and habitat necessary to support these large numbers of birds (Myers, 1984).

When animal species assemble at a particular area, they utilise individual but overlapping segments of the habitat (MacArthur, 1958). Karr (1980) stated that resource utilization pattern and the community organization are determined by a combination of variables. The availability and preference of the food organisms, feeding behaviour and utilization of the habitat for feeding and reproduction differ in co-existing animal species. Periods of rapid change in prey populations offer important opportunities to study the relationship between predators and their prey. In particular, such studies can yield information on the functional response of predators to a changing prey environment and the role of prey dynamics in the regulation of predator population size.

3.1 Introduction

Cauliflower is a cruciferous vegetable that is naturally high in fibre and B-vitamins. It is said that the cauliflower has originated around the Mediterranean Sea. Ancestor of cauliflower is Brassica cretica which has been descended from the wild cliff cabbage, Brassica oleracea var. sylvestris, a native of coastal region of Europe and Africa. Cauliflower is cultivated worldwide in different climatic conditions ranging from temperate to tropics during most of the cropping seasons and is available round the year. Curd is the economic part of cauliflower and is an intermediate stage between vegetative and reproductive stage. It was introduced in India during the Mughal period. In 1822 a botanist Dr Jemson, In-charge of Company Bagh, Saharanpur, U.P introduced it in India from Kew Garden London. 

Abstract

Fermentation in food processing is the process of converting carbohydrates to alcohol or organic acids using microorganisms; yeasts or bacteria under anaerobic conditions. Fermentation usually defines the desirable action of microorganism to enhance food safety by inhibition of pathogens, modify their sensory properties, improve their nutritional value by removing anti-nutritive compounds and by enhancing bioavailability of components. Pulses and Legumes are the major source of dietary nutrients all over the world. Fermentation can be the most simple and economical way of improving their nutritional value, sensory properties and functional qualities. Pulses and legume based fermented food products offer opportunities to include probiotics, prebiotics and fibers in the human diet. In the Indian subcontinent, making use of fermented food and beverages using local food crops and other biological resources is very common, although the nature of the products and the base material varies in different regions. This chapter focuses on some of the indigenous fermented foods produced in the country that have not received the scientific attention they deserve in the last decades. Products produced from different pulses and legumes substrates fermented by lactic acid bacteria, yeast and/or fungi are included.

1. Oil Cakes

Several varieties of oil seeds are produced in India. Oil seeds contain 40 to 50 percent oil and residues left after extraction are known as oil cakes. Oil seed cakes are generally referred as concentrated organic manure because of their high content of plant nutrient, nitrogen in particular as compared to conventional farmyard manure or compost. Oil cakes also invariably contain 2 to 15 percent oil depending on the method of extraction. Oil seeds are further demarcated into edible and non-edible oil seed cakes depending on their palatability to animals. Both type of oil seed cakes can be used as organic manures, but edible oil seed cakes are generally used as animal feed as warranted by socio-economic reasons (Bhardwaj, 1995). Non-edible cakes are generally used as organic manure to supply major plant nutrients like nitrogen, phosphorus and potassium.

Potential of Non-edible Cakes

The authentic estimates of quantity of non-edible cakes produced in the country are not available because the oil yielding trees are grown and scattered our vast tract of the country. Only a part of oil bearing seeds of these trees are being collected and processed. According to an estimate, annual production of non-edible oil seed cakes was of the order of 3.8 million tonnes annually which on average can provide 87, 25 and 57 thousand tonnes of N, P2 O5 and K2 O respectively (Singh and Gurumurti 1984).

Introduction

“Sustainable development as a concept represents the latest step in a long evolution of public concerns with respect to both natural resources and environment”. It is defined as “development that meets the needs for the present without compromising the ability of future generations to meet their own needs”. This definition indicates that to meet their needs, the present generations have no right to overuse natural resources and the environment, which will ultimately threat the living standards of the future generations. Therefore, stewardship of both natural and human resources is of prime importance (Freenstra 1997). Advocates of sustainable development perceive that the biosphere imposes limits on economic growth, express a lack of faith in either science or technology as leading to human betterment, are extremely averse to environmental risks, support redistributive justice and egalitarian ethics, profess concern over population growth and have faith in the wisdom of human capital development, and have survival of species and protection of the environment and of minority cultures, rather economic growth per se, as goals.

Electronic health records contain extensive clinical, demographic, diagnostic and treatment information that can support medical research and decision-making. This chapter examines the characteristics of healthcare big data and the challenges associated with EHR storage, integration, quality and analysis. It presents an analytics pipeline covering data ingestion, secure storage, preprocessing, integration, pattern discovery, visualization and clinical decision support. Machine learning and deep learning methods are discussed in relation to clinical phenotyping, risk stratification, predictive epidemiology and adverse-outcome prediction. The chapter also addresses data privacy, governance, regulatory compliance, explainability, scalability and bias, highlighting the need for secure and interoperable EHR-mining systems that generate clinically useful knowledge.

Mushrooms have been part of fungal diversity for around 300 million years. A mushroom is a macro fungus with a distinctive fruiting body, which can either be epigeous (above ground) or hypogeous (underground) and large enough to be seen by naked eye and to be picked up by hands. They lack the green matter (chlorophyll) present in plants and grow on dead and decaying organic materials, as phytoparasite or in mycorrhizal association with plants. From these decaying substrate, they absorb their nutrition with the help of fine thread like structures (mycelium), which penetrate into the substratum and are generally not visible on the surface. After the mycelium has grown profusely and absorbed sufficient food materials, it forms the reproductive structure which generally comes out of the substrate and forms fruiting body, commonly known as mushroom. Mushrooms can be divided into four categories (i) Those that are fleshy and edible fall into the edible mushroom category i.e., Agaricus bisporus; (ii) Mushroom that are considered to have medicinal applications are referred to as medicinal mushrooms i.e., Ganoderma lucidum; (iii) Those that are proved to be or poisonous or suspected of being poisonous are named poisonous mushrooms i.e., Amanita phalloides; (iv) those in a miscellaneous category, which include a large number of mushrooms whose properties remains less defined. The toxic/poisonous species commonly referred to as ‘toadstools’ are objects of fear and distrust and have led to certain amount of inhibition and taboo towards mushroom consumption.

Use of mushrooms as food by man has been practiced since time immemorial and probably predates any historical records. The early civilizations of Greeks, Egyptians, Romans, Chinese and Mexican appreciated mushroom as delicacy, knew something about their therapeutic value, often used them in religious ceremonies. Greeks regarded them as strength food for warriors while Romans considered them as ‘Food of Gods’ and Chinese regarded mushrooms as ‘Elixir of life’. Much referred ‘Somrus’ in ancient Indian literature is actually a decoction of mushroom. Archeological and other accounts reveal that ancient man used mushroom in religious ceremonies. The Aztecs of South America referred mushroom as ‘teononacte’ (God’s flesh) and worshipped a group of mushrooms as being divine. The high esteem in which mushrooms were held in different civilizations is also indicated by the restriction of the use of many species to the rulers.

Currently 14000 mushroom species are known to exist. Of these about 50 % or 7000 species are considered to posses varying degrees of edibility and almost 3000 species from 31 genera are regarded as prime edible mushrooms. To date only 200 of them are experimentally grown, 100 of them economically cultivated, approximately 60 commercially cultivated and about 10 have reached to industrial scale production in many countries. Furthermore, about 2000 are medicinal mushrooms with varieties of health attributes. The number of poisonous mushroom is usually reported to be relatively small (approximately 1 %), but there is an estimate that about 10 % may have poisonous attributes while 30 species are considered to be lethal.

A marketing strategy of a business is the game plan of an organization for approaching its target market effectively. Marketing strategy is also used to target the prospective customer and converting them into loyal consumers for the brand and services being offered by the companies.

A marketing strategy is the building block of a marketing plan and consists of the value which the company wants to offer, its key message which the company wants to convey to the target market and other elements which are key in the area of marketing.

Vegetables play an important role in human nutrition and health making them important in Indian agricultural economy. The productivity of vegetable crop is seriously affected by several biotic and abiotic stresses and makes the economic conditions of the Indian marginal farmers worst. Under Indian conditions, 25-40% of the total vegetable produce is going waste due to lack of post-harvest storage and processing facilities in the country. Conventional plant breeding methods have improved vegetable crop plants bringing together a wide array of genes responsible for novel productivity and quality traits. However, sometimes, genes needed for crop improvement are not available in the existing germplasm. In genetic engineering, individual genes affecting the traits of economic importance are introduced in commercial cultivars. It is a targeted approach to improve the crop plants, which attempts to avoid the transfer of large blocks of genetic material. It requires identification and cloning of desirable gene and its subsequent transfer in plant species for improvement. Transgenic technologies offer many scientific advantages in breeding for improved vegetable crop quality and performance. However, very few genetically engineered horticultural crops have been released to farmers. As of 2005, one thousand million acres of transgenic crops have been planted globally covering 40% of the United States land area out of which 75% of the area is devoted to cotton, 50% to corn and 85% to soybeans in the United States of America (ISAAA, 2006).
