Need for Impact Assessment

Fisheries Research is an economic activity. Like any other investment propositions, resource allocation to Fisheries Research needs to be justified. The society or the donors are always interested to know what happened to the money invested in Fisheries Research. It is important to document the returns and/or benefits accrued from the research investment. Objective assessment of research investment helps in making decision and allocating resources in high returns research portfolio. It also helps to know which research areas and programs benefit the poor and regions. In the paradigm shift, the donors are seeking evidences on impact of past funding as a basis for future financial support. Systematic impact assessment forms the basis for efficient resource allocation in alternative research programs competing for financial support. Research programs demonstrate better historical performance, in terms of benefits generated for the society, and are rated higher for attracting required research resources. Impact assessment studies are also getting more prominence as the international environment is rapidly changing due to many emerging complex problems. Socioeconomic and environmental problems, like poverty, international trade, degradation of natural resources, are growing fast and the donors are looking for the research programs, which can overcome these challenges. Therefore, systematic impact assessment studies would form a strong base for higher research funding to overcome many regional, national and global problems.

Introduction

Developments in both hardware and software sectors of computer science raised high expectations and strong vision to solve number of problems in all sectors of economy. Introduction of personal computers (PC) in 1970’s created vision of paperless offices, simplified computing, automated process control, management information system, expert system etc. Initially, it had greater impact on agricultural research and development in developed countries in the form of Information and Communication Technology (ICT). Growth of companies with promises to provide specialist software to farmers and growers during 1980’s is a clear indicator of the high expectation and visualization of ICT in the field agricultural research and development. A review of agricultural software availability and use has been made by an international team in 1997 called FARMSOFT. This review covered on eight countries viz. Belgium, France, Germany, Israel, Italy, Portugal, Spain and The Netherlands. It was found that in 1996 out of 1315 software related to agriculture, 39% were in category of management, 26% were in category of animal husbandry, 8.9% in category of crop production, 7.0% in category of machinery and process control, 0.1% in category of irrigation and 19% in others category. Comparison of change in software inventory in 1996 with respect to 1994 revealed that there is around 15% growth in the agricultural software development. The higher positive growth was in the category of management software (38.40%) followed by animal husbandry (10.45%) and others (10.44%). However, highest negative growth was observed in the category of irrigation (-163.15%) followed by crop production (-53.85%) and machinery and process control (-30.95%). This indicates that overall agricultural software inventory was growing but while growth in the software related to agricultural management was sufficiently high, there was sharp decline in categories of irrigation and crop production. This change in pattern may be attributed to saturation of software and bottlenecks due to limitation of related technological innovations, socio-economic adoption and infrastructural facilities.

The thrust of Indian Agriculture in the post green revolution period was an enhancing agricultural productivity through sustainable practices. In order to achieve its, the government of India implemented a national level programme for the development of rainfed areas through the watershed approach. A watershed is a community-based programmes that is organized in a specifically earmarked area with a defined time frame and focuses on a wide range of issues and activities for integrated development of the village. The main focus is laid on water, food and fodder security and employment generation

The watershed approach aimed at augmentation and stabilization of production and productivity, minimizing ecological degradation, reduction in regional disparity, opening up of greater opportunities for employment of rural poor in the rainfed areas. A similar approach has been adopted for developing the more resource poor areas — drought prone, desert and wastelands — and to provide sustainable means of livelihoods to the rural poor in these areas. Promotion on the economic development of the village community, optimum utilization of the watershed’s natural resources like land, water, vegetation, employment generation and development of the human and other economic resources of the village and encourage restoration of ecological balance in the village are the main objectives of watershed development programmes.

Introduction

Many a times research programs appear potentially promising before implementation yet fail to generate expected impacts or benefits. Impact Assessment (IA) has become an integral part of any research study. It, not only justifies the investment made, but also helps in prioritizing projects. The ultimate objective is to make an impact from the output of the projects carried out. Researchers and extension functionaries involved in the upliftment of farmers/fishers through various research projects, training activities and interventions are bound to justify their resource utilization through unbiased and objective based impact assessments.

What is Impact Assessment?

Impact assessment (IA) is a structured process for considering the implications, for people and their environment, of proposed actions while there is still an opportunity to modify or abandon the proposals. It is applied at all levels of decision-making, from policies to specific projects. Impact Assessment is simply defined as the process of identifying the future consequences of a current or proposed action. The difference between input, output, outcomes and how they encompass the monitoring and evaluation programmes of any organisation later transforming into the study of impacts has been shown in Figure 3.1.

Impact assessment extends programme evaluation by examining the broader and longer-term changes associated with an intervention, programme, policy or technology. In agricultural extension and rural development, impact assessment is important for determining whether interventions have produced meaningful, sustainable and attributable changes in farming communities, livelihoods, technology adoption, institutional systems and environmental conditions. This chapter introduces the concept, purpose and contexts of impact assessment and explains the Impact Assessment Framework through the relationship between inputs, activities, outputs, outcomes and impacts. It discusses the meaning and selection of impact indicators and examines social and behavioural, socio-cultural, technology-level, environmental and institutional indicators relevant to agricultural extension. The chapter further presents quantitative, qualitative, participatory and mixed-method approaches to impact assessment, including statistical and econometric methods where appropriate. Environmental Impact Assessment and Social Impact Assessment are also considered as important dimensions of comprehensive assessment. Particular attention is given to issues of causality, attribution, data quality, time lags and external influences that can affect the interpretation of impact findings

Introduction

Land and water are important natural resources available for agriculture crop production. The resource is available either for agriculture or for human / animal consumption, from precipitation in the form of rain. According to National Commission of Agriculture, half of the available land in India will continue to depend on dry land even after our total surface and ground water potentials are fully exploited by 2025 A.D. So far efforts were made in improving the irrigation potential to step up crop production and very little attention has been paid to dry lands. Considerably improved but the farmers in dry land areas are still suffering.

5.1 Introduction

A theoretical system is what we construct in one mind’s eye to model the empirical system. Theories and models provide the researcher concepts, definitions’, variables and hypothesis that may be tested by analyzing relevant data (Bhatia, 1990). A theory emerges from the research and so does a particular research pursuit from the theory. The theory is a set of interrelated constructs, definitions and propositions that present a systematic view of phenomena by specifying relations among variables, with the purpose of explanation and predicting the phenomena (Kerlinger,1973). A researcher seldom conducts research without any concern for theory. A theory provides major orientation to research by helping to define the type of data to be collected and theory emerges from facts (data) collected during research. Theory and facts are not opposed but intervened, the theory is not speculation and scientists are concerned with theory as well as facts (Anonymous, 2011). It is possible to conduct evaluation without paying any attention to theory and forms of evaluation, but such evaluation studies lack internal validity because these are not based on the rigorous evaluation research methodologies (Campbell and Stanlay,1966). According to Alkin and Christie (2004), evaluation has grown on three pillars of orientation i.e. research orientation, decision making orientation and assessing worth. The field of evaluation research can be defined as “the use of scientific methods to measure the implementation and outcome of programmes for decision-making purposes” (Rutman, 1984). The concept of evaluation research has been an issue of debate among academicians. The academicians consider that evaluation research differs from both basic research as well as applied research (Douglah, 1998).

Introduction

The process of agricultural modernization has produced three distinct types of agriculture. These are industrialized, green revolution and low-external input and unimproved (Chambers et al. 1989) . The industrialized and the green revolution agriculture have been able to respond to the technological package, producing high input, high output systems of agriculture. Most agricultural systems in the industrialized countries count as high external input systems save for the relatively small number of organic farmers (Pretty 1995) . In the countries of the Third World, high-external input systems are found in the large irrigated plains and deltas of South, Southeast and East Asia, and parts of Latin America and North America, but also in patches in other regions. In the industrialized countries farmers modernized by introducing machinery, replacing labour, specializing operations and changing practices to ensure greater production. In the green revolution areas the success lay in agricultural scientists breeding new varieties of stable cereals that matured quickly, and use of inorganic fertilizers, pesticides, machinery, credit and water regulation.

1. Introduction
Global food security threatened by climate change is one of the most important challenges in the 21st century to supply sufficient food for the increasing population on diminishing agricultural land while sustaining the already stressed environment. Global agricultural production is highly vulnerable as key crops such as maize, wheat, rice, and legumes will be negatively affected by climate change. The study showed that each degree Celsius increase in global mean temperature is estimated to reduce the average global yield of cereal crops by 6-15%. Further, predicted changes in climate may affect water availability and key soil processes such as respiration and nitrogen (N) mineralization, thus key ecosystem functions such as carbon (C) storage, nutrients, and water availability. Although crop growth simulation models are being utilized to understand the impact of climate change scenarios on aboveground biomass, the roots and their architecture, which are essential for plant adaptation and productivity, need to be studied more due to the difficulty of observing them during the plant life cycle. The root system and its architecture are highly responsive to external environmental conditions such as soil moisture, nutrients, temperature, pH and microbial communities; therefore, it is high time to study below-ground responses to future climate scenarios. The study of plant roots represents a highly promising yet underexplored area of research related to plant growth. While the aerial parts of plants have received significant attention due to their visibility and accessibility, the underground portions have been largely overlooked due to the challenges in observing and sampling them and the disruption caused when roots are removed from the soil. Plants’ efficiency of water and mineral nutrient uptake largely depends on how effectively new root tips penetrate soil horizons and how these roots eventually die and decompose. The plant’s ability to access soil resources depends on the size of its root system and the activity of its growing root tips. Root growth is influenced by both genetic factors and environmental conditions. For example, fine root dynamics vary with the seasons, with increased vegetative growth and nutrient release occurring during the monsoon months. (Kumar et al., 2020). Further research is needed to assess how different tillage and water management practices affect rooting behaviours, soil water extraction, and nutrient uptake.

Introduction
Antimicrobial resistance (AMR) represents one of the most significant public health challenges of modern times. The discovery of antibiotics in the early 20th century revolutionized medicine, transforming once-fatal infections into manageable conditions and enabling life-saving procedures such as organ transplantation, chemotherapy, and joint replacement surgery. However, the overuse and misuse of antibiotics in human medicine, veterinary practice, and agriculture have accelerated the development of resistant microorganisms. Today, infections caused by resistant pathogens claim millions of lives worldwide each year, with the World Health Organization warning of a postantibiotic era in which minor injuries or routine surgeries could again become life-threatening. Although AMR is often framed within the context of hospital-acquired infections and clinical treatment failure, its implications extend much further. In particular, AMR has significant consequences for physical and health fitness. For athletes, soldiers, patients in rehabilitation, and physically active individuals, resistant infections can disrupt performance, delay recovery, and compromise long-term health. The increasing prevalence of resistant organisms in community environments—including gyms, swimming pools, and sports facilities—further raises concern. This chapter situates AMR at the intersection of clinical medicine, sports science, and community health. It explores how resistant pathogens affect physically active populations, complicate rehabilitation processes, and influence outcomes in both competitive and recreational Fitnes. It also highlights the global and national responses to AMR, preventive strategies relevant to Fitnes and rehabilitation, and the role of healthcare professionals

Types of Biomedical Waste

1. Infectious waste: waste contaminated with blood and other bodily fluids (e.g. from discarded diagnostic samples), cultures and stocks of infectious agents from laboratory work (e.g. waste from autopsies and infected animals from laboratories), or waste from patients with infections (e.g. swabs, bandages and disposable medical devices)

2. Pathological waste: human tissues, organs or fluids, body parts and contaminated animal dead bodies

13.1 Introduction
Since the United Nations Framework Convention on Climate Change was founded in 1992, efforts have been undertaken to address climate change, which is today a serious problem for the entire globe. These programmes made an effort to lessen GHG emissions and lessen the effects of climate change. There have been a number of significant accords made, including the Kyoto Protocol in 1997, the Copenhagen Accord in 2009, and the Paris Agreement in 2015. Despite these accords, the Intergovernmental Panel on Climate Change (IPCC)’s most recent assessment contends that current decarbonization efforts fall short of the goal of keeping global temperature increases to 1.5°C over pre-industrial levels by 2050. Instead, it is anticipated that the temperature will have increased to 2.7°C by 2050 (Anonymous 2021). Analysing how climate change is affecting this sector of the economy is crucial. Fruit production is significantly hampered by changing precipitation patterns, rising temperatures, and extreme weather events. The growth, development, and production of fruit crops may be impacted by these changes, which could lead to financial losses and problems with food security. Improved methods and technologies for fruit production must be used to address these problems and comply with the objective of limiting the increase in global temperature. Adopting sustainable farming methods, bolstering water management systems, investing in crop varieties resistant to climate change, and improving postharvest storage and transportation technology may all be necessary to achieve this. Additionally, strengthening agroforestry systems and safeguarding biodiversity can support the fruit industry’s attempts to adapt to and mitigate climate change. Additionally, in order to lessen the effects of climate change on fruit agriculture, international collaboration and cooperation are essential for the adoption of suitable policies as well as the exchange of knowledge and resources. One example is encouraging collaborations between governments, agricultural organisations, researchers, and farmers to create and implement climate-smart practises and technologies. It is important to support various carbon capture and storage (CCS) technology that can remove CO2 from the atmosphere or prevent its release in order to fulfil the Sustainable Development

Insecticide based plant protection in India as well as in the world resulted in wide variety of environmental and health issues. Insecticides although gave satisfactory control of target pests initially, have posed serious issues such as resistance, resurgence and residue and also contamination of water bodies, food chain leading serious ill effects in humans, mammals, soil beneficial microbiota etc. After thorough examination of scientific evidences and facts on ill effects of synthetic organic insecticides, much emphasis was given for biological control including parasitoids, predators, entomopathogens, biopesticides, microbial control etc. in order to overcome above ill effects.

Horticulture, the branch of agriculture that deals with the art, science, technology, and business of cultivating plants, plays a vital role in food security, nutrition, and economic development globally. This diverse sector encompasses a wide array of activities, broadly categorized into:
• Pomology: The cultivation of fruits and nuts.
• Olericulture: The cultivation of vegetables.
• Floriculture: The cultivation of ornamental flowering plants.
• Landscape Horticulture: The design, construction, and maintenance of landscapes.
• Post-harvest Handling: The management of horticultural produce after harvest to maintain quality and reduce losses.
Each of these components is intricately linked with weather conditions, making the horticulture sector highly vulnerable to climate change.

Climate change is a complex problem involving varied interactions between the environment, natural resources (land, crops, animals and water) and people. These interactions are likely to change the ecological and agricultural landscape, and therefore influence agricultural and animal production. The Intergovernmental Panel on Climate Change (IPCC) has dictated that global warming/climate change could lead to many environmental problems i.e., Drought, floods, crop and animal farming, food production, and health hazards etc. Agriculture is closely dependent on the endowment of natural resources and environmental conditions of soil and climate. India is divided into many agro—climatic zones depending upon rainfall, agriculture and soil fertility. The agro climatic conditions of India and the various other factors that largely determine the cropping patterns vary throughout the country. Warangal district falls into two agro climatic regions namely Southern Telangana Zone and North Telangana Zone.

Introduction

Climate change and agriculture are interrelated issues, both of which take place on a global scale. Global warming is projected to have significant impacts on conditions affecting agriculture, including fluctuation of temperature, carbon dioxide, glacial run-off, precipitation and the interaction of these factors (Sehgal et al., 2006; Kalra et al., 2008). These conditions determine the carrying capacity of the biosphere to produce enough food for the human population and for domesticated animals. The overall effect of climate change on agriculture will depend on the balance of these effects. Assessment of the effects of global climate changes on agriculture might help to properly anticipate and adapt farming to maximize agricultural production. Droughts, which have frequented different parts of India through the history, have been responsible for many famines, rural poverty and migration despite development of impressive irrigation potentials. Similarly, abnormal temperatures, high velocity winds and humidity during critical stages are known to significantly affect crop growth and development, pest incidences and epidemics, demand on irrigation resources and finally food production. Over the past few decades, the main-induced changes in the climate of the earth due to multifarious human activities linked to develop have become the focus of scientific and social attention. The predicted changes to agriculture vary greatly by region and crop. Findings for wheat and rice are reported here: The study found that increase in temperature (by about 2 ºC) reduces potential grain yield in most places. Regions with higher potential productivity (such as northern India) were relatively less impacted by climate change than areas with lower potential productivity (the reduction in yields was much smaller). Climate change is also predicted to lead to boundary changes in areas suitable for growing certain crops. (Kalra et al., 2002-2003). Reduction in yields as a result of climate change is predicted to be more pronounced for rainfed crops (as opposed to irrigated crops) and under limited water supply situations because there are no coping mechanisms for rainfall variability. The difference in yield is influenced by baseline climate. In sub-tropical environments, the decrease in potential wheat yield ranged from 1.5 to 5.8%, while in tropical areas the decrease was relatively higher, suggesting that warmer regions can expect greater crop losses.

Global warming has become a worldwide concern after feeling the rise of temperature much more clearly after 1990. Global warming has negatively affected agricultural production throughout the world attributed by the climate change parameters. Effects of climate change on horticultural crops reported nowadays include problems of biotic and abiotic stress, yield loss, quality loss, etc. To understand the impact of climate change problems in horticulture, it is prerequisite to comprehend the issues related to global carbon cycle, climate change phenomenon, relationship between climate change variables and direct as well as indirect climate change effects.

Agriculture is dependent directly on weather and indirectly on the consequences of climate change. Changes in temperature, precipitation, incoming solar radiation and CO2 concentration are expected to impact crop growth to a greater extent. The overall impact of climate change on worldwide food production is considered to be low to moderate only when there is successful adaptation strategies towards climate change (IPCC, 1998). Global agricultural production could be benefited by the doubling CO2 concentration. All sectors including agriculture will be impacted by the adverse effect of climate change imposed on water resources (Gautam and Kumar, 2007; Gautam, 2009). India is expected to face more seasonal variation in temperature with more warming in the winters than summers (Christensen et al., 2007; Cruz et al., 2007). The frequency of drought occurrence is increasing due to variations in the monsoonal rainfall. Climate change is posing a great threat to agriculture and food security. Water is the most critical agricultural input in India, as 55% of the total cultivated areas do not have irrigation facilities.

Even with the variations in climate conditions, food accessibility for the present generation is assured, but as far as the future is concerned there is still the uncertainity of agricultural production. All climate models predict that there will be more extreme weather conditions, with more droughts, heavy rainfall and storms in agricultural production regions. Such extreme weather events will inf luence pest and disease occurance, imposing severe risks of crop failure. In India, climate change could be a potential threat towards food security due to population growth, industrialization and economic development. India’s climate could become warmer under conditions of increased atmospheric carbon dioxide.

1. Introduction

Uttarakhand is extremely vulnerableto climate-related changes due to its varied geography and rich glacier mass. The relationship between climate change and agriculture is not a new phenomenon. In the last 50 years, there has been a lot of academic focus on dealing with climate change issues in agriculture. Climate change is believed to affect agriculture by inducing changes in farmer’s behaviour, quantity, quality, cost of production, changes in production, consumption, prices & trade patterns; changes in market responses at global & local levels and these changes not only depend on the domestic and international adaptive capacity their economic impacts also vary by region, by sector, and by stakeholders’ groups. Climate change is a major global environmental problem and also an issue of great concern to all countries, irrespective of their size or level of development. It is established that adverse impacts are likely from increased frequency of extreme weather, floods & droughts, and submergence of coastal areas due to sea level rise and extreme climate variability. It is considered that mountain regions are vulnerable to climate change & it will have direct impacts on livelihoods as most of the economic & livelihood sectors are vulnerable to the effects of climate change.
