Operated by two bullocks and one man, it is attached to the yoke with ropes for puddling rice fields, covering half an acre per day. It has a draught of 200-220 kg and ploughs to a depth of 4-5 inches and width of 5-6 inches in black and red soils. Repairable locally, its annual maintenance costs range from Rs 0.5 to 1.0, with an operational cost of Rs 25 per hectare. It is widely used in the coastal belt of Andhra Pradesh (Guntur and West Godavari). (ICAR, 1960).

IKS stands for Indigenous Knowledge Systems. When applied to pest and disease management in agriculture, IKS refers to the traditional and local knowledge systems developed by communities over generations to deal with agricultural challenges, including pests and diseases.

5.1 Key Aspects of IKS for Pest and Disease Management

1. Traditional Practices: Indigenous communities often have developed practices based on observation and experience to control pests and diseases. These may include specific plant combinations, crop rotations, or timing of planting to minimize pest damage.

2. Natural Remedies: IKS often includes knowledge of natural substances and plants that have pesticidal or medicinal properties. Examples include the use of neem, garlic, chilli, or certain plant extracts to deter pests or control diseases.

3. Cultural Practices: Traditional farming practices may include rituals or timing of activities that are believed to influence pest and disease outbreaks. For instance, planting during specific lunar phases or following certain cultural calendars.

4. Biological Control: Indigenous knowledge may also involve the use of natural enemies of pests, such as predators or parasites, to manage pest populations. This aligns with modern biological control principles.

5. Crop Diversity: Traditional farming systems often promote crop diversity, which can help naturally manage pest and disease pressures by reducing monoculture effects and providing habitats for beneficial organisms.

Seed treatment refers to the application of chemical or biological substances to seeds before planting. This process is designed to protect seeds from diseases, pests, and other adverse conditions that may affect germination and early growth and can improve overall crop yield and quality. Seed treatment can involve the use of fungicides, insecticides, bactericides, and other agents that help improve seed health and vigor. Seed treatment is a crucial step in ensuring healthy crop production. By investing in seed treatment, farmers can achieve better crop establishment and reduce the need for subsequent interventions, leading to more sustainable and cost-effective agricultural practices.

4.1 Importance of Seed Treatment

1. Disease Control: Seed treatment helps to protect seeds and seedlings from soil-borne and seed-borne pathogens, reducing the risk of diseases that can impair seed germination and seedling growth.

2. Pest Protection: Treated seeds are less likely to be damaged by insects and other pests that may be present in the soil. This protection can lead to higher seed survival rates and better crop establishment.

3. Improved Germination: By reducing the incidence of diseases and pests, seed treatment can enhance the germination rate and uniformity of seedlings, leading to more robust and consistent crop stands.

4. Nutrient Provision: Some seed treatments include nutrients or growth promoters that help improve seedling vigor and early development, ensuring that young plants have a better start.

5. Resistance to Environmental Stress: Seed treatments can help seeds withstand adverse environmental conditions such as drought, salinity, and temperature fluctuations, improving the overall resilience of the crop.

Soil fertility management refers to the practices and techniques used to maintain and improve the fertility of soil. Soil fertility is crucial for agriculture because it determines the soil's ability to provide essential nutrients to plants, support their growth, and sustain productivity over time. Effective soil fertility management aims to optimize soil health and productivity while minimizing environmental impacts.

3.1 Key Aspects of Soil Fertility Management Include

1. Nutrient Management: This involves supplying essential nutrients (nitrogen, phosphorus, potassium, etc.) to the soil through organic or synthetic fertilizers to meet the needs of crops.

2. Soil Amendments: Adding organic matter (such as compost or manure) or other amendments (like lime or gypsum) to improve soil structure, water retention, and nutrient availability.

3. Crop Rotation and Diversification: Rotating crops and diversifying plant species can help manage nutrient depletion and improve soil health by reducing pest and disease pressures.

4. Conservation Tillage: Minimizing soil disturbance through reduced tillage or no-till practices helps preserve soil structure, reduce erosion, and maintain organic matter content.

5. Cover Cropping: Planting cover crops during fallow periods or between main crops helps prevent soil erosion, improve nutrient cycling, and enhance soil fertility.

Soil is a loose surface material that provides water, nutrients, and structural support to agricultural plants. It is made up of 45% minerals, 5% organic components, 25% air, and 25% water. Our soils are said to be the source of 95% of the food we eat, either directly or indirectly.

The basis of the food chain is healthy soil. Our soils are the foundation of agriculture and the growing media for almost all plants that provide food. Good crops come from good soils, and healthy crops feed people and other animals. Food quantity and quality are, in fact, closely related to soil quality.

A healthy soil is a dynamic, living ecosystem. It is packed with both microscopic and larger organisms that carry out a multitude of essential tasks, such as nutrient cycling—the process of turning dead and decaying matter and minerals into plant nutrients controlling plant diseases and insect and weed pests, enhancing soil structure, which has a positive impact on the soil's ability to hold water and nutrients, and ultimately increasing crop productivity. Because healthy soil retains or increases its carbon content, it also helps to mitigate climate change.

Traditional agricultural practices have been an integral part of food production in India since ages. These practices have the potential to mitigate the adverse effects of climate change with spatial and sequential diversity (Patel et al., 2020). Traditional Agriculture can be defined as a primitive style of farming that involves the intensive use of indigenous knowledge, traditional tools, natural resources, organic fertilizer and cultural beliefs of the farmers (Abeysekara et al., 2021). It is noteworthy that it is still used by about 50% of the world population. Traditional agriculture can be defined as a set of knowledge- practice-trust nexus which has developed by its adaptive nature and passes on to the next generation through a cultural transmission that explains the relationship between living beings with their environment (Berkes et al., 2000).

In India, several institutions are working towards women’s empowerment and gender equality. The Ministry of Women and Child Development is the nodal agency responsible for promoting women’s rights and empowerment. The National Commission for Women (NCW) is another statutory body that works to protect and promote women’s rights. Additionally, there are various autonomous organizations such as the National Institute for Entrepreneurship and Small Business Development (NIESBUD), the Indian Institute of Entrepreneurship (IIE), and the Women’s Technology Park (WTP) that provide training and support to women entrepreneurs. Furthermore, there are numerous non-governmental organizations (NGOs) such as the Self Employed Women’s Association (SEWA), the All India Women’s Conference (AIWC), and the YWCA of India that work towards women’s empowerment and gender equality. These institutions provide a range of services including education, healthcare, legal aid, and economic empowerment programs to support women’s development and well-being.

The development discourse on women nationally and internationally as discussed above, moved from Women in Development (WID) to Gender and Development (GAD) and Women’s Empowerment. This was reflected in the Government Plans and Policy Documents in their journey through more than six decades. Since independence many schemes were launched for the emancipation of women in the country.

In the Fifth Five Year Plan (1974-79), the development approach replaced the social welfare approach. This recognized women’s productive role and her contribution. The Sixth Five Year Plan (1980-85), is a landmark in the history of women’s development by emphasising on health, education and employment. In the Seventh Five Year Plan (1985-90) priority was given for programmes to improve the status of women. A major development for the empowerment of women was the 73rd constitutional amendment to the Panchayat Raj Act in 1993. This amendment specified that one-third of the posts of Sarpanch and Chairman of the block level assemblies (Samiti) and the district assembly (Zila Parishad) will be women. Today, mobilization of women’s groups particularly in rural areas has become a major strategy in bringing them into the public domain, developing leadership and increasing their access to resources. Indian women have higher visibility in the national and state policies.

The Digital India campaign of the Government with special emphasis being laid on digital financial transactions and cloud technologies will go a long way in the evolution of better services and amenities for women, especially in agricultural domains.

Empowering women in agriculture through digital technologies can significantly enhance their productivity, economic opportunities, and overall well-being. Here are key strategies and areas to focus on:

1. Access to Information and Resources

Digital Platforms: Utilize mobile apps and websites to provide women farmers with information on weather forecasts, crop management, pest control, and market prices.

E-learning: Offer online training and tutorials on sustainable farming practices, financial management, and new agricultural technologies.

2. Financial Inclusion

Mobile Banking: Promote mobile banking services to help women access credit, savings, and insurance products. Digital financial services can make it easier for women to manage their finances and invest in their farms.

Women empowerment refers to the process of enabling women to increase their control over their lives, resources, and decision-making power. It involves promoting gender equality, challenging gender stereotypes, and addressing the social, economic, and political barriers that prevent women from reaching their full potential.

The Government of India declared 2001 as the ‘Year of Women’s Empowerment and the National Policy for the Empowerment of Women came into force from 2001. The policy approaches that were underlined in this policy concerned gender equality. The policy proposed that the legal system be made responsive and gender sensitive to women’s needs. It stated that women should be economically and socially empowered through focused efforts.

Women Empowerment has Several Dimensions

1. Economic Empowerment: Access to education, employment, credit, and other economic resources.

2. Political Empowerment: Participation in decision-making processes, leadership positions, and political representation.

3. Social Empowerment: Challenging gender stereotypes, promoting gender equality, and addressing social norms that limit women’s potential.

4. Legal Empowerment: Access to justice, legal rights, and protection from discrimination and violence.

5. Psychological Empowerment: Building self-esteem, confidence, and self-reliance.

Today, health promotion of the poor has emerged, worldwide, as a vital area for policy research and action. Healthcare is the responsibility of the constituent states and territories of India.

Food security: Gender dimensions

Standards have improved gradually over a period of years. But the burden of ill health is borne disproportionately by different population subgroups and people of lower socio-economic status, especially women, as they consistently experience poor health outcomes. Gender inequality leads to food insecurity and is also its leading cause. National food security is largely dependent on agricultural sector. The FAO articulates that food security is achieved when people at the individual, household, national, regional and global levels, at all times, have physical, social and economic access to sufficient, safe and nutritious food to meet their dietary needs and food preferences for a healthy and active life.

Rural women rarely own a control land and lack access to agricultural inputs, technology, training, extension services and marketing services. Despite being major contributors to agricultural production, they have little or no access to the means of production. They face restrictions in mobility due to social conditions, hence face a narrower range of labour markets than men including harsh working conditions and lower wage rates.

Climate change significantly impacts agriculture, altering growing conditions, crop yields, and the livelihoods of farmers. Rising temperatures and shifting precipitation patterns can lead to more frequent and intense droughts, floods, and storms, which disrupt planting and harvesting schedules and reduce crop productivity. Changes in temperature and precipitation can also exacerbate pest and disease pressures, making it harder for farmers to protect their crops. Additionally, the increased frequency of extreme weather events can damage infrastructure and soil health, further challenging agricultural systems. These effects pose serious threats to food security, necessitating the development of climate-resilient farming practices and crop varieties, as well as policies that support sustainable agricultural development and climate adaptation.

The climate change is not “gender neutral”. Women and girls experience the greatest impacts of climate change, which amplifies existing gender inequalities and poses unique threats to their livelihoods, health, and safety.

Climate change effect on women

1. Reduced Agricultural Productivity: Climate change leads to crop failures, reduced yields, and changed growing seasons, affecting women’s income and food security.

2. Increased Water Scarcity: Changes in precipitation patterns and increased evaporation lead to water scarcity, forcing women to travel farther for water, reducing their time for other activities.

3. Soil Erosion and Degradation: Flooding and erosion caused by climate change degrade soil quality, reducing fertility and affecting crop growth, further threatening women’s livelihoods.

Introduction

‘Health is wealth’ is a common saying. Every individual should take care of his physical and mental health. During work performance, if an activity leads to any health problem it is referred to as an occupational health hazard, which needs urgent attention. In agriculture, occupational health problems sometimes amount to incurable diseases/disorders.

Meaning of Occupational Health Hazards

Occupational hazard is something that causes harm to a working person, in terms of injury or ill health, damage to property, workplace environment, or a combination of both. In India, farm women contribute as farmers, agricultural workers, and entrepreneurs. As per the 2012 census data, women’s share was 55%, which is projected to be 65% by 2025. They are the backbone of the agricultural rural economy but still are one of the most vulnerable groups. Though nowadays, mechanization is gaining importance due to various reasons, it has yet not reached farm women, who are still not recognized as ‘farmers’, and the machinery is designed to suit the men’s folk. The role of women in farming operations like transplanting, harvesting, post-harvest management, and packaging, which are drudgery-prone, are on the increase. Considering these facts, the tools’ designers should give due thought when designing agricultural tools and equipment, to address farm women’s drudgery.

Gender analysis is the first and the foremost critical step towards gender responsive planning and programming. It involves collection and analysis of sex disaggregated information. It examines the differences, commonalties and interactions between women and men. Gender analysis examines women’s and men’s specific activities, conditions, needs, access to and control over resources, access to development benefits and decision-making.

Gender analysis helps to clarify the specific and often different capacities, vulnerabilities, needs and coping strategies of men and women, and indicates where opportunities for targeting effective strategies lie. Established patterns of gender inequality and inequity can be explored, exposed and addressed. This may provide opportunities and entry points to develop programs that support efforts to build more equitable gender relations. It aims to achieve positive change for women.

Elements of Gender Analysis

a) Natural: Land, water, forests, rivers etc.

b) Economic: Work opportunities, wages and remuneration, remittance, credit and production inputs.

c) Social: Formal and informal education and social services- religion and cultural norms like dress, defining private and public spaces.

Introduction

Women perform two-thirds of the world’s work hours, yet are poor in resources and are poorly represented in positions of power. Most of the low-income women in developing countries are primarily employed in agriculture, but many literatures show that men have been the primary adopters and shapers of agricultural technologies. These inequalities are seen in all parts of the world. Without acknowledging gender inequalities, economic development and globalization cannot be achieved. Gender bias is a universal phenomenon and there are a number of issues that farm women face.

Importance of Gender Mainstreaming in Agriculture

Indian Women spend 354 minutes a day, compared to 36 minutes a day by men, on household activities including cooking and child care. In developing countries, nearly 75 - 80 percent of women are involved in agriculture. They face gender issues in land ownership, access to credit, market, technology, seed, water, information, education and other services. NSSO survey (2010) revealed that 40% of male farmers want to quit farming due to less profitability. Gradually, male farmers are migrating to earn from non-farming activities. In this situation, women have to look after household as well as farming activities.

The Indian farm women have extensive workloads with triple responsibility for farm, household and community. Gradually their work is becoming harder due to climate change, degradation of natural resources, natural calamities, male migration and changing agricultural technologies. Women are extensively involved in crop production, horticulture, livestock management, post harvest operation, fisheries, agroforestry and household activities. Majority of their time is devoted towards collection of fuel, fodder and water, growing vegetables in homestead and rearing backyard poultry. They also considerably contribute for household income as agriculture wage earners and through cottage industry.

Women play a significant and crucial role in agricultural development and allied fields. The nature and extent of women’s involvement in agriculture varies greatly from region to region. But regardless of these variations, women are actively involved in various agricultural activities.

As per Census 2011, out of total female main workers, 55 per cent were agricultural labourers and 24 per cent were cultivators. However, only 12.8 per cent of the operational holdings were owned by women, which reflect the gender disparity in ownership of landholdings in agriculture. Moreover, there is concentration of operational holdings (25.7 per cent) by women in the marginal and small holdings categories. Worker Population Ratio (WPR) of women (24 %) is lower as against men (54.4 %) in the country. The workforce participation rate for rural females is higher at 30.5 percent against urban women participation rate of 20.20 percent (Mo SPI, 2022-23). As per the Annual Periodic Labour Force Survey (PLFS) Report 2022-23, agriculture had the highest estimated percentage distribution of female workers, ie. 64.3 %, with 76.2 % in rural areas and 11.7 % in urban areas.

Sex

Sex is the biological make-up of male and female human beings. It is biological difference between men and women. Sex is universal, permeant, Biological. John money draw the distinction between the biological differences and behavioural characteristics that differentiates male and Female. First person used Gender opposite to sex. Founder of Gender Identity clinic at John Hopkins University in the Baltimore in US in 1966.

Gender

First used by anna Oakley. It is neutral term, dynamic, change over time and place. It is a socially constructed roles and responsibilities assigned to men and women in a given society. It refers to socio-cultural differences between males and females. Gender determines what is expected, allowed and valued in a woman / man in different contexts. In simple words, gender refers to the set of relationships between men and women at a particular point of time in a given society

Gender Blindness

It is the failure to recognize that gender as an essential determinant of social outcomes impacting projects and policies. Gender-blind policy ignores the different situation, roles, needs and interests of women, men, girls and boys.

A student investigator confronted time constraints, such as course credit pressure, and resource constraints, such as physical, budgetary, and managerial constraints, in the current investigation. However, every effort and consideration made the study as objective and scientific as feasible. Despite the researcher’s best efforts, the study depends on the respondents’ opinions, which may or may not be devoid of their perceptions and biases.

As a result, it is a modest piece of labour that may be completed over a more extended period.

Suggestions for Future Research

• The findings of the present study warrant the need for further investigations in several directions. The following suggestions are made for further research in the following areas.

• The study was confined to one state; therefore, the results cannot be generalised to the whole country. Similar analyses can be taken up in other states to generalise the results.

The quality and effectiveness of extension services are critical to the agricultural sector’s long-term viability and output. Farmers have been getting agricultural information from extension workers via interpersonal communication for many years. Still, the number of extension employees has been declining while the number of farming families has increased. As a result, the country’s current extension service needs to improve in reaching out to farmers with timely and relevant agricultural information. ICTs are considered a partial answer to quickly getting information to the growing number of farming households because relevant and timely information is vital in agriculture. Farmers may receive up-to-date knowledge and information on agricultural technologies, best practices, markets, price patterns, and customer preferences through its use.

Since farmers in many parts of India, including West Bengal , are becoming more mobile and internet savvy, disseminating useful real-time information about crops, soils, climate, cultivation practices, financing, produce storage, and marketing to farming communities is more important and challenging. Many concerted efforts from the government, non-government organizations, and industry are now required to make our farmers ICT -friendly so that the benefits of rapidly evolving technological advancements in farm production, storage, and marketing can be shared equally among all communities and sectors of farming.

5.3 Content analysis of websites

5.4 Statistical tools used for the analysis of data.

5.5 Preparation of report

India is considered a pioneer in software development and a favourite destination for IT-enabled services. West Bengal is predominantly an agrarian State. Comprising only 2.7% of India’s geographical area, it supports nearly 8% of its population. There are 71.23 lakh farm families, of whom 96% are small and marginal farmers. The average size of land holding is only 0.77 ha. However, the State is bestowed with diverse natural resources and varied agro climatic conditions that support the cultivation of a wide range of crops.

The net cropped area is 52.05 lakh ha, comprising 68% of the geographical area and 92% of arable land. The cropping intensity is 184%. However, as the State is in the humid tropic and the Bay of Bengal is close by, it often must face natural vagaries like floods, cyclones, hailstorms, etc. Though the State has a surplus production of rice, vegetables and potatoes, a huge gap exists between the requirement and production of pulses, oilseeds, and maize. The deterioration of soil health due to imbalances in chemical fertilizers, the paucity of suitable improved seed varieties, inadequate farm mechanization, unorganized marketing structure, etc., is a major challenge to agricultural growth.

Websites

Information science is an interdisciplinary field that skirts the study of the organization, production, retrieval, storage, retrieval, use of information, and dissemination. Information and Metric studies of storage and recovery are the primary areas of Information Science. Today’s challenges for information personnel are to pave the way through enormous volumes of information brought about by different means.

The World Wide Web (WWW ), an information space, is a complex structure that incorporates all types of information that need different users and a layperson to the researcher. It is a system of interlinked hypertext documents approached via the Internet . The web pages can be viewed in a way that contains images, text, videos, and several multimedia through the forms of a web browser and negotiated between them with the help of hyperlinks.

It is also a system of multimedia that supports uniquely formatted, using markup languages like HTML or digital documents. These scripting languages support links to other documents, video files, graphics, and audio.

The term ‘Webometrics ’ (Bajorneborne & Ingwersen, 2001) was coined for content analysis , search engine performances, quantitative analysis of web related phenomena, links, and web technology analysis from an information science perspective.

A literature review attempts to discover, locate, and synthesize relevant research reports, articles, books, and other resources relating to a study subject. The review can be based on published sources like journal articles, conference papers, research abstracts, chapter books, research institution websites , and so on, as well as unpublished materials like theses and dissertations. By examining the literature, a researcher can take advantage of past research and results made by professionals to get the most out of their research.

Examining literature is an important part of every research project since it gives the investigator the information, they need to frame the study on the chosen topic. It directs an investigation on the appropriate path, keeping up with the most recent data.

Studies on Broad Areas of Webometrics

Webometric studies, ranging from earlier to more contemporary studies, have been recognized and organized under the following headings:

• Studies on the Growth and Development of Webometrics

• Studies on theoretical studies of content analysis

• Studies on Web Content Analysis

• Studies on web usage analysis

The agriculture sector in India accounts for about 20.2 per cent of its gross value added (GVA) and 17.34 per cent of the total export earnings. It employs approximately 60 per cent of the country’s workforce. It is an unavoidable source for generating demand for industrial goods and services, and domestic savings in rural India are a huge source of resource mobilization in the Indian economy. This sector plays a key role in ensuring national food security and, in the meantime, national security as well. For these reasons, the development of agriculture has a strong multiplier effect on the economy. There is also an increasing consensus that a globalizing economy and a long-term economic development plan for India are practicable only if it has agriculture and raises rural incomes as its central concern.

ICT and Information Needs of the Stakeholders

Information and communications technology (ICT) is an extension-related term used in information technology (IT) that emphasizes the role of unified communications and the integration of telecommunications like wireless signals and telephone systems and computers; it is also useful in the software system, middleware, storage, and audio-visual, that enable users to store, transmit, access, manipulate information by understanding the whole process.

17.1. Introduction

Grounded Theory (GT) is a systematic methodology in the social sciences that involves the construction of theories through methodical gathering and analysis of data. Developed by Barney Glaser and Anselm Strauss in 1967, GT is widely used in qualitative research to generate theories that are grounded in empirical data. Unlike traditional research methods that test hypotheses, GT allows theories are to emerge from the data itself, making it a valuable tool for exploring complex social phenomena.

This chapter provides an in-depth exploration of Grounded Theory, including its origins, key principles, methodologies, applications, and criticisms. By the end of this article, readers will have a thorough understanding of GT and its significance in qualitative research.

16.1. Introduction

Game theory is a mathematical framework designed for understanding and analyzing strategic interactions among rational decision-makers. It has applications in various fields such as economics, political science, psychology, biology, and computer science. The foundational premise of game theory is that the outcome of a decision made by one agent depends on the decisions made by others. This chapter provides a comprehensive overview of game theory, covering its fundamental concepts, types of games, solution concepts, and applications.

16.2. Fundamental Concepts

16.2.1. Players

In game theory, a player is any individual or entity that makes decisions within the context of the game. Players are assumed to be rational, meaning they aim to maximize their own utility or payoff based on their preferences and the information available to them.

15.1. Introduction

Meta-analysis is a statistical technique used to combine the results of multiple studies to produce a single, more precise estimate of the effect size of a particular intervention or association. It is a powerful tool in research, particularly in f ields such as medicine, psychology, education, and social sciences, where it is often necessary to synthesize evidence from numerous studies to draw meaningful conclusions. This chapter provides a comprehensive overview of meta-analysis, including its history, methodology, advantages, limitations, and applications.

15.2. Historical Background

The concept of meta-analysis dates back to the early 20th century, but it was not until the 1970s that the term was coined by Gene V. Glass. Glass defined meta-analysis as “the statistical analysis of a large collection of analysis results from individual studies for the purpose of integrating the findings” (Glass, 1976). Since then, meta-analysis has evolved significantly, with advancements in statistical methods and software making it more accessible and robust.

15.3. The Need for Meta-Analysis

15.3.1. Accumulation of Evidence

In many fields, particularly in medicine and psychology, a large number of studies are conducted on the same or similar research questions. However, individual studies may have small sample sizes, leading to low statistical power and inconclusive results. Meta-analysis allows researchers to pool data from multiple studies, increasing the overall sample size and statistical power, thereby providing a more reliable estimate of the effect size.

Project managers need to make sense on the many data that they have. Analytical tools are used in project management to achieve such need. Such tools are used to create a forecast of potential outcomes based on the variations present in the environmental and project variables. There are different types of analytical tools used and one of the most common tools is regression analysis.

14.1. Multiple Regression

Concept: Multiple regression is the most commonly utilized multivariate technique. It examines the relationship between a single metric dependent variable and two or more metric independent variables. Multiple regressions are often used as a forecasting tool. Goal is to use the linear composite of two or more continuous and/or categorical variables (predictors) to: 1) predict scores on a single continuous variable (criterion), or to 2) explain the nature of the single continuous criterion variable from what is known about the predictor variables. In prediction, the criterion is the main emphasis because decisions are made on its value, but often times, it is difficult to directly measure or obtain a subject’s actual score on the criterion; therefore, it is important to estimate or predict one’s criterion score based on the value of the predictor scores.

13.1. Introduction

The Delphi technique is a systematic, interactive forecasting method that involves gathering expert opinions to make informed decisions, predict future trends, or address complex problems. The core idea behind this technique is to use the knowledge and insights of experts in a structured manner to produce well-informed and reliable outcomes. By combining expert judgment with iterative feedback, the Delphi method allows for deeper analysis, greater accuracy, and a better understanding of complex issues that cannot be easily solved through traditional data analysis or quantitative methods (Ismail and Taliep, 2023).

Originally designed for defence-related forecasting, the Delphi technique has since evolved into a versatile tool used across a wide range of fields, such as business, healthcare, education, public policy, environmental science, and social research. Its versatility stems from its ability to gather expert opinions in a manner that allows for rigorous analysis of complex issues, without the constraints of traditional group meetings or face-to-face discussions.

12.1. Introduction

Artificial Neural Networks (ANNs) are computational models inspired by the way biological neural networks in the human brain process information. They consist of interconnected nodes or “neurons” arranged in layers: an input layer, one or more hidden layers, and an output layer. Each neuron in the network processes data and passes the results to the next layer. ANNs are designed to recognize patterns, learn from data, and make predictions or classifications based on that learning.

In an ANN, the connections between neurons are weighted, meaning each connection has a strength or value that determines the influence of one neuron on another. Through a process called training, the network adjusts these weights to minimize errors in its predictions. This is typically done using techniques like backpropagation, where the error is propagated backward through the network to update the weights (Abiodunet al., 2018).

ANNs are highly versatile and have been applied across various domains, including image and speech recognition, natural language processing, and decision-making systems. Their ability to model complex relationships in large datasets makes them a crucial component in the field of machine learning and artificial intelligence (Ahmed et al., 2023).

11.1. Introduction

Fuzzy Cognitive Mapping (FCM) is a powerful soft computing technique that integrates elements of fuzzy logic and cognitive mapping to model complex systems. It allows for the representation of causal relationships between variables in an interpretable and flexible manner, making it particularly valuable for analyzing and simulating real-world dynamic systems. FCM has its roots in cognitive science, systems thinking, and artificial intelligence, enabling researchers and practitioners to model uncertainties and interdependencies effectively (Tyrovolas et al., 2023). The approach is particularly advantageous when dealing with complex, ill-structured problems where traditional mathematical modeling techniques fall short. By capturing expert knowledge and combining it with computational techniques, FCM helps in making informed predictions and policy decisions.

It is widely applied across multiple domains, including environmental management for sustainability assessments (Özesmi and Özesmi, 2004), decision support systems in business and governance, healthcare for medical diagnostics and treatment planning (Apostolopoulos et al., 2024), and socio economic planning for policy analysis and forecasting (Gray et al., 2015). Furthermore, its adaptability has led to its increasing integration with artificial intelligence, machine learning, and big data analytics, making it a promising approach for tackling contemporary challenges.

10.1. Introduction

Decision-making is a fundamental aspect of human life, influencing choices in both personal and professional settings. Every individual, whether consciously or unconsciously, engages in decision-making daily, ranging from simple tasks like selecting a meal to complex strategic planning in organizations. However, decision-making becomes increasingly challenging when multiple conflicting criteria are involved. The presence of numerous factors, each with varying degrees of importance, often creates ambiguity and uncertainty, making it difficult to arrive at the most suitable option. To address these challenges, structured decision-making methodologies have been developed to provide a systematic and logical framework for evaluating alternatives.

One such widely recognized method is the Analytical Hierarchy Process (AHP), introduced by Thomas L. Saaty in the 1970s. AHP was designed to assist decision-makers in breaking down complex problems into a structured and systematic hierarchy. This approach allows for a step-by-step evaluation of different factors, making it easier to analyze their relative importance. By structuring a problem into different levels - such as goal, criteria, sub-criteria, and alternatives - AHP provides clarity in decision-making and enhances consistency in judgments. The method is particularly beneficial when dealing with decisions that involve both tangible and intangible factors, as it allows subjective preferences to be quantified systematically (Saaty, 2008).
