Introduction

India’s rural economy has benefited greatly from the dairy sector. It has played a significant role in bringing about socioeconomic change. India’s dairy industry has undergone significant change as a result of the White Revolution. The “White Revolution” can be credited with increasing milk availability and providing rural India with a stable source of employment and income. The business has drastically changed to meet India’s increasing demand for milk and milk products. India is currently the world’s greatest producer of milk. The Operation Flood Program is credited with this title. The dairy market in India is projected to increase at a compound annual growth rate (CAGR) of 6.61% from 2024 to 2029, from an estimated US$26.11 billion in 2024 to US$35.96 billion by 2029 (Indus Food, 2024). With over 8 crore farmers employed and a 5% national GDP contribution, the dairy industry in India is vital to the country’s economy. With around 25% of the world’s milk supply and a massive livestock population of 536.76 million animals, it tops the world in milk production. With major markets in the United Arab Emirates, Saudi Arabia, the United States, Singapore, and Bhutan, India exports approximately 63,738.47 metric tonnes of dairy products in 2023–2024, generating US$ 272.64 million.

Land, a non-renewable resource, is central to all primary production systems. Over the years, the country’s landmass has suffered from different types of degradations. Land degradation can be defined as lowering of land productivity due to the deterioration of land’s physical, chemical and biological condition. Physical land degradation is due to water erosion, wind erosion, compaction, crusting and water logging and chemical degradation is due to the processes of salinization, alkalization, acidification and nutrient depletion. Biological degradation is due to the reduction of soil biota and organic matter, degradation of vegetation and impairment of activities of microflora and fauna. Land degradation is steadily increasing due to the growing pressure on land and unsustainable land use. Land degradation and the associated loss of soil productivity and quality is of great concern both from food production and environmental conservation point of view. An ever-increasing population created enormous pressure on land resources.

ABSTRACT

Dairy farming plays a significant role in rural economy. It provides more avenues for increasing rural incomes and sustaining livelihood. Milk and other dairy products are a major source of protein and calcium for vast vegetarian population of India and demand is likely to double within a decade. Many of the educated youth in rural areas are going back to dairy farming as a natural choice with passion, getting involved deeply, continuously learning and innovating in the process. However these young and intuitive farmers face many challenges especially with regard to technical input and availability of green fodder round the year. In order to address these problems, this study was conducted in Muktsar district of Punjab. The young farmers selected belong to age group ranging from 24-35 years. Seventy percent of the respondents were graduates, among them 25 percent being technocrats. About 65 percent had medium family size (5 members). Eighty five percent of respondents had small land holding ranging from 5-8 acres. For majority of the respondents’ dairy was the primary occupation. Sixty percent of the respondents had obtained 45 day artificial insemination (AI) training from Dairy Development Board, Punjab and themselves did AI on their farm. Many (75 percent) had herd size of 35-40 animals. Majority of the farmers had hired labour for milking and daily care of animals with family members involved in management of the farm. Most of them (65 percent) believed in preparing their own silage and breed improvement. The study revealed that many educated youth in dairy farming were of progressive and scientific temper with entrepreneurship potential but were facing many impediments like low milk yield (4.5 – 6.5 kg/ animal/day), poor breed up gradation, green fodder shortage, a large number of services per conception (3 in majority cases) with artificial insemination (AI), low competence of veterinary service providers in remote rural areas in addition to high veterinary costs, difficulty in marketing milk from crossbred dairy cows due to low preference. It was felt that if sincere and sustained efforts were made by all the stakeholders involved, dairy farming had the potential for all round socio-economic development of rural areas.

The woody perennial shrubs have been the integral part of the traditional agro forestry system in arid region since ancient times. Inhabitants of the region rely on these species for food, fodder, fuel wood and other day-today requirements since long. Among woody perennials arid shrubs also have a major role in stabilization of drifting sands in the arid ecosystem. Out of about 682 species of Indian arid Zone (Bhandari, 1990), shrubs constitute 70% of the total flora in the Indian desert, yet they cover over 70-80% of desert landscape. Thus shrubs are less in variety, they are ecologically more successful biotypes in the desert environment.

Abstract

Pest damage is an age old problem of Indian agriculture. The increased accumulation of green house gases always changes the climatic conditions that have potential effects in increasing pest population.  The insect pests are cold-blooded animals and their body temperature varies with the surrounding temperature. Thus, any change in the climate and weather is bound to influence the activity of pests. The pests are directly influenced by temperature, precipitation, humidity, wind speed and other environmental factors in terms of their occurrence, development, reproduction, distribution, migration and adaptation. In many cases the insect out breaks which classified as gradient out breaks are not self-driven but are entirely dependent on external environmental conditions. For example, the number of aphids has frequently been shown to be correlated with several environmental factors. Such correlations indicate an understanding of aphid out breaks. The increased temperature as a result of climate change has several implications for agricultural pests. These are as follows: (i) changes in population growth rates, (ii) increased number of generations, (iii) extension of development season, (iv) extension of geographical range, (v) increased over wintering, (vi) changes in crop-pest synchrony, (vii) changes in interspecific interactions, (vii) increased risk of invasion by migrant pests, (ix) introduction of alternate hosts, and (x) availability of over wintering hosts.

Introduction

In view of the accepted importance of analysis, the workload on soil, plant and water testing laboratories has increased considerably in recent years. Therefore, analytical methods have needed to be accelerated through the automation of instruments. Almost all instruments either contain inbuilt computers or can interface directly with micro processors, thereby simplifying instrument operation and providing versatility for the analyst. Most operations can be performed through keyboard commands. This type of instrument automation enables:

11.1 Principles and Framework for Risk Assessment
11.1.1 Introduction
Risk assessment is an indispensable scientific tool in evaluating the safety and potential impacts of genetically modified (GM) crops on human health, animal welfare, and the environment. It provides a structured, evidence-based framework for identifying hazards, characterizing risks, and proposing mitigation strategies before the approval and commercialization of GMOs. In the context of biotechnology and regulatory biosafety, risk assessment ensures that GM crops meet both national and international standards for biosafety and sustainability.
11.1.2 Definition of Risk Assessment
Risk assessment is defined as the systematic process of identifying, evaluating, and characterizing the potential adverse effects arising from exposure to a GMO or its products, under specified conditions of use.
Risk = Hazard × Exposure
Where hazard is the potential to cause harm, and exposure is the likelihood of encountering the hazard.
11.1.3 Objectives of Risk Assessment in GM Crops
• To evaluate the safety of GM crops for human and animal consumption.
• To assess the potential environmental impacts, including effects on biodiversity, gene flow, and ecosystem interactions.
• To ensure that regulatory decisions are science-based, transparent, and precautionary.

Introduction

India is believed to be the native of several economic plant species which have spread to various part of the world. While agriculture continuous to stagnate in underdevelopment and insufficiency in food production. India enjoys variable climatic conditions and multiplicity of topographic feature, elevation and rainfall. The climatic conditions and soil type are so diversified that the various combinations of these factors favor unlimited production of a wide variety of crop plants. Now started move and rapid changes are taking place largely as results of bio-technology to advance scientific agriculture. Bio-technological approaches introduction of genetically modified in plant protection. A small percentage of former are well educated on the advantages of scientific forming and are adopting newer technique at limited extent.

Balanced crop nutrition is a most reaJized critical factor in allowing crops to give their full yield potential. The application of macro and micronutrients through manures and fertilizers to achieve this balance is an integral practice in modern crop production system. Macro and microelements have long been recognized as being associated with changes in the level of many diseases and yield and /or quality of crops. Three major elements N, P, and K are the most studied nutrients which chiefly affect relative resistance of crop plants to various diseases. Others macro/micro/beneficial nutrients including Ca, Mg, S, Mn,Te, Zn, Mo, Si, Bo and Cu have shown varying degrees of disease suppression/induction on many crop species under various environmental conditions. Crop nutrition influence plant health through: i. affecting the growth, reproduction, virulence, and survival of pathogens; ii. resistance and tolerance, predisposition and escape in the host crop; and iii. root exudates and microbial interactions facilitatingbiological control. Balanced crop nutrition can protect crops from pathogens by: i. avoiding plant stress, which may allow crops to better withstand the attack of pathogens and ii. manipulating nutrients to the advantage of crops and disadvantage of the pathogen. The modern intensive agriculture which mainly relies on chemical inputs (fertilizers and pesticides) and fertilizer responsive HYVs (high yielding varieties) has led the self sufficiency in food production in India and several other countries of the world. But, the indiscriminate and imbalance use of chemical fertilizers along with exhaustive cropping initiated several second generation problems including widespread micronutrient deficiencies and increased attack of several insect-pests and pathogenic diseases. The excessive use of nitrogen and no or reduced application of phosphorus, potash and other micronutrients is creating conducive conditions for several crop pathogens and their insect vectors. This situation frequently results in serious crop losses during favourable environmental conditions for disease development. The specific role of macro and micronutrients in maintaining crop health, effect of their dose and form of application on suppression /induction of various diseases and interaction with other soil/ environmental factor (s) will be discussed in following sections.

2.1. Open source satellite data

The satellite images have been invaluable information sources for Natural Resource Management. They provide synoptic view of the Earth periodically helping in inventory, surveying, and monitoring in agriculture, hydrology, geology, mineralogy, land cover, land use and environment. Free global satellite image data of spatial resolutions of 1m to 1 km and spectral resolution of single band to hyperspectral are available from an increasing number of sources (Table 2.1).

Abstract

Rural women play a vital role in farming system operations and contribute substantially in the physical aspect of farming, livestock management, postharvest and allied activities. Around 43% of the agricultural labour force of developing countries is composed of women dependency. India has achieved self sufficiency in agricultural production, but a considerable amount of production gets spoiled in every year due to inadequate post-harvest management, processing, infrastructure and skill. To uplift the livelihood and economic conditions of the rural women there is an urgent need to impart trainings for skill development regarding the value addition of horticultural crops. This offers tremendous opportunities for women occupation but also inculcate entrepreneurial characteristics in them. Trainings and skill development are useful for rural women as they can add more value to the seasonal fruits and vegetables and generate varieties of products namely Pickle, Murabbaa, Chutney, Jam, Sharbat etc. These efforts enhance their family income by around 30-40 thousands per annum as they fetch more prices of raw produce after processing. Moreover during peak production times glut only promote produce and profit loss. Instead of direct marketing of their produce they can do value addition of their produce and then sell them in market, it not only increases the value of their products but the prices also enhance by many folds. After giving training to rural women, they are motivated to go for self marketing of their produce at domestic and village level. Similar way these trainings can transform the life style and income level of farming families comprehensively.

Introduction

It comes to the market early in the season, particularly the low chilling peaches and growers get remunerative prices due to the non-availability of other fresh fruits in the market. It has high nutritive value, being rich in protein, essential amino acids, minerals, and vitamins. Peaches originated in China, where its culture dates back to 3000 years. Although it is not exactly known how and when the peach reached India, it is opined that some traders might have carried over the stones of peach from China to Kashmir. Peaches were introduced by Mr. Alexander Coutts in Himachal Pradesh in 1870. Later on, its cultivation was initiated in the mid-hills of Himachal Pradesh on the advice of an American horticulturist, Prof. R. W. Hodgson. Some low-chilling varieties of peach were also introduced at Punjab Agricultural University, Ludhiana in 1968 from California. peach with a strong flavour and aroma.

INTRODUCTION

Biodiversity can be useful as an ecosystem indicator for conservation and monitoring, through continuous assessment of its main properties including stability, primary productivity, exploitation tolerance and even global environmental changes (Douglas et al., 2012). Crustaceans are found one of the most morphologically diverse taxonomic groups on the planet (Martin and Davis, 2001). Among them, decapods are the most studied taxon, mainly on account of the commercial interest of some species and their great diversity (Isarch and Munoz, 2015). Decapods are chiefly composed of marine species that live in waters depths ranging from shallow to deeper than 5000 m. Isarch and Munoz (2015) described the importance of this group lies in several factors such as the great biomass they represent, their significant role in marine food webs and the commercial interest of many decapod species. Order Decapoda comprises the commercially important shrimps, crabs and lobsters. Out of 649 species of marine crabs so far recorded from Indian waters, only 12 species of edible crabs namely Portunus sanguinolentus, P. plagicus, Charybdis feriatus, C. lucifera, C. annulata, C. natator, Scylla serrata, S. tranquebarica, Matuta lunaris, Sesarma tetragonum and Varuna litterata, which inhabit the coastal waters and adjoining brackishwater environments, support commercial fisheries (Menon and Pillai, 1996). However substantial quantities of crabs are landed every year as by-catches of shrimp trawlers and indigenous fishing units throughout the county.

India represents one of the major contributors to the world production of marine crustaceans. Shrimps constitute as the main seafood export industry for the major foreign exchange earner as well as a source of livelihood for millions of fish workers. As shrimps are targeted for fishing, information on the present status of the fishery is critical for implementation of proper management. Some of the important penaeid shrimps that support commercial fisheries along the Indian seas are Fenneropenaeus indicus, P.semisulcatus P.monodon, P.merguiensis, P.japonicus, P.penicillatus, Metapenaeus dobsoni, M.monoceros, M. affinis, M. kutchensis , M. brevicornis, Parapenaeopsis stylifera, P.hardwickii, P.sculptilis, P.maxillipedo, P.uncta, Trachypenaeus curvirostris, Metapenaeopsis stridulans, Parapenaeus longipes, Solenocera crassicornis and S.choprai (Mohan Joseph and Jayaprakash, 2003). Rajkumar et al. (2015) carried out molecular identification of shrimp species, Penaeus semisulcatus, Metapenaeus dobsoni, Metapenaeus brevicornis, Fenneropenaeus indicus, Parapenaeopsis stylifera and Solenocera crassicornis from Tamil Nadu, India.

Introduction

Government initiatives aimed at supporting small-scale enterprises and fostering women’s entrepreneurship are crucial for driving economic development, job creation, and social empowerment. Small-scale enterprises, including micro, small, and medium enterprises (MSMEs), play a vital role in the economy by contributing to employment, innovation, and poverty reduction. Similarly, women entrepreneurship offers significant potential for promoting inclusive growth, tapping into underutilized talent, and advancing gender equality in business leadership.

Small-scale enterprises often face challenges like limited access to funding, poor infrastructure, regulatory barriers, and market limitations. Women entrepreneurs, on the other hand, encounter additional obstacles such as socio cultural norms, limited access to resources, and gender biases in the business world. To address these issues, governments globally have introduced policies and initiatives aimed at supporting small enterprises and encouraging women’s participation in entrepreneurship.

When ANOVA indicates significant differences among treatment means, further analysis is required to determine which particular means differ significantly. This chapter deals with post-ANOVA procedures used for detailed comparison of treatment means. It introduces methods such as critical difference, least significant difference, and multiple comparison procedures. Particular attention is given to Scheffé’s method, Newman–Keuls method, and Duncan’s New Multiple Range Test. The chapter explains the principles, calculations, and interpretation of these techniques using forestry examples, including comparisons among tree species and provenances. It also discusses considerations for selecting an appropriate multiple-range or comparison method according to the objectives and number of comparisons involved.

Abstract

Tripura is expected to be highly prone to the consequences to climate change because of its geo-ecological fragility, strategic location, its trans-boundary river basins and its inherent socio-economic instabilities.  Environmental security and sustainability of the state is and will be greatly challenged by the impacts of climate change in coming years.
Climate and weather can substantially influence the development and distribution of insects.

1. Introduction

Plants are reliable sources for the treatment of diseases in different parts of the world (Eisenberb et al., 1993; Cowan, 1999; Hostettmann et al., 2000) and they have been unique sources of medicines and constituted the most common use of biodiversity (Hamilton, 2004; Hiremath and Taranath, 2010). Their use contributes significantly to primary healthcare delivery (Holetz et al., 2002) as they are regarded as invaluable sources of pharmaceutical products (Olalde, 2005).

Traditional medicine, with medicinal plants as their most important component, are sold in market places or prescribed by traditional healers in their homes (Von Maydell, 1996). As a result of this strong dependence on plants as medicines, many ethnopharmacological studies have been conducted to determine their safety, efficiency and discovery of new active principles from them. Only, 1,100 plants have so far been thoroughly examined for their medicinal practices in the world (Dobson, 1995).

Herbal medicine have been in use since time immemorial and are still the mainstay mainly in the developing countries because of their better cultural acceptability, better compatibility with the human body and lesser side effects (Kamraj, 2000).

Fruit drop is a premature shedding of fruitsbefore harvesting for commercial purpose. There are so many reasons for fruit drop like internal (Hormonal balance, morphological and genetical) and external (biotic and abiotic) factors. Fruit drop is very much serious in some fruits like apple, peach, currant, mango, citrus etc. Fruit drop may occur at various stages of fruit growth,starting right from fruit setting till its harvesting. It may be natural, environmental or pest related.Losses due to fruit drop at various stages have long been a serious threat to the fruit growers. After determining the actual cause of fruit drop, adoption of a suitable control measure can bring relief to the growers. Among different drops, pre-harvest drop is of great economic importance which can cause serious crop loss to farmer.

Abstract

India is an agriculture based country and livestock production is an integral component of farming system and it is generally considered a key asset for rural livelihoods. It offers advantages over other agricultural sectors and it plays a crucial role in the rural economies of developing countries like India. Livestock provide high quality food, cash income and employment. Livestock production is largely in the hands of women. Most of the animal farming activities such as fodder collection, feeding, watering, and health care, management, milking and household-level processing, value addition and marketing are performed by women. Besides, considerable involvement and contribution of women, gender inequalities also exist in Indian villages. Therefore, there is a need to correct gender bias in livestock sector. Efforts are needed to increase the capacity of women to negotiate with confidence and meet their strategic needs.
