6.1 Introduction 
Lignocellulosic Biomass (LCB) generated from the global consumption of fruit and vegetables rapidly generates approximately 140 billion metric tons of agricultural waste. Environmental pollution associated with these wastes, like land pollution, and increased greenhouse gas emissions, can be reduced through the bioconversion of wastes (renewable biomass resources) into value-added products in biorefineries (Babu et al., 2022). These value-added products synthesized for utilization in industries such as biofuels, biomaterials, or biochemicals are effective, reuseable, and enhance sustainability. These bioproducts are recuperated into useful biomolecules and oils for the food industries and dyes for the textile industries. The sustainability of these products can be acquired efficiently through costeffective pretreatments and bioprocess optimization methods (Haldar et al., 2020). The initial stage of value product chain development is the process modelling and optimizing, which, due to its complex nature and large scale, faces challenges in raw material availability, cost competitiveness, upscaling, and lack of technological maturity (Gerassimidou et al., 2021). Optimization of production processes like fermentation and chemical synthesis for manufacturing value-added products has become a focal point in research enhancement of biorefineries. There has been a revolution in the technology used in process designing and manufacturing practices in biorefineries. Advanced Artificial Intelligence (AI)-based approaches like Genetic Algorithm (GA), Fuzzy Inference System (FIS), and Artificial Neural Network (ANN) are being utilized along with conventional tools to optimize variables interacting in production processes. These techniques increase overall efficiency and enhance prediction accuracy and output of value-added products (Banerjee et al., 2025). Optimization of the bio processes enables higher productivity in parallel with lower environmental burdens. AI-based approaches integrated with conventional approaches need a large amount of experimental historical data to be successfully carried out (Arias et al., 2023). Advancement of biorefineries due to the rapid demand of value-added products as well as a solution to the greenhouse emissions, the integrated application of AI for process analysis needs to be understood. This chapter is a contribution towards upscaling the current knowledge base related to different approaches for the enhancement of production for value-added products. The chapter discusses the conventional techniques for value-added production and various optimization models. There is further discussion of advancements in the traditional approach using AI-based approaches and their features and benefits in biorefinery. Apart from different AI-based models, AI integrated with life cycle analysis for sustainability is also briefed. Finally, the chapter addresses current limitations in the field and outlines potential future directions for research and development.

5.1 Introduction
Bioprocess engineering is becoming more advanced form of technology due to the many changes taking place in the field. The world is in dire need for creative, well thought out, and innovative approaches to problems associated with sustainable biomanufacturing, treatment customization, and the production of bio-based goods. One of the most notable advancements is the rise of synthetic biology, which allows for bioproduction at unprecedented levels where microbes could be modified for better bioproduction. More traditional approaches is strain improvement and metabolic engineering, which revolve around mutation-based processes and other forms of gene transfer technologies. The applications of new, non-traditional methods such as machine learning and artificial intelligence have completely revolutionized the way bioprocessing and its monitoring, as well as optimization, is done. On top of that, the drive towards sustainability has further motivated the use of green bioprocessing techniques which aim to minimize environmental harm. In parallel with these advances, regenerative medicine and gene treatment is opening doors to a new era of personalized medicine. In a world where change is constant, these accomplishments and innovations help us to take full advantage of what bioprocess engineering has to offer, as well as face the intricate challenges that the modern world encounters (Awasthi, 2022). In recent years, the field of biotechnology has undergone transformative and profound change that is marked by new breakthroughs and improvement which can affect several fields such as medicine, agriculture, and ecology. The emergence of tools like CRISPR-Cas9, synthetic biology, bioprinting, precision medicine and regenerative medicine are some of the new trends in biotechnology. These changes are recognizing the limits on the biological sciences and expanding them at the same time. Synthetic biology is another technology that includes the strategy and production of new genomic parts, related tools, and re-designs of traditional ones for valuable purposes. The scientists are modifying living organisms to perform useful functions like manufacturing biofuels or pharmaceuticals. Synthetic biology raises concerns about biosecurity and the unintentional release of artificial organisms into the environment, despite its enormous potential to address global challenges like renewable energy and sustainable resource usage (Jain, 2022). This article introduces advancements in bioprocess engineering with specific focus on advancements brought about by emergence of CRISPR. Bioprocess engineering is the application of process engineering principles to biological systems and has been a multidisciplinary field unto itself. Since its isolation as a groundbreaking genome-editing system, CRISPR has vastly improved the precision, efficiency, and scalability of both microbial and mammalian cell manipulation. This has resulted in numerous breakthroughs in pharmaceuticals, biofuels, and industrial enzymes, a major milestone for synthetic biology, and metabolic engineering (Jinek et al., 2012). The CRISPR revolution has changed

4.1 Introduction
4.1.1 Overview of Genomics in Biotechnology
The genome of an organism serves as the ‘blueprint of life’ (Baeza, 2024) and functions as an information repository (Goldman & Landweber, 2016), containing the necessary information for the synthesis of molecules, cells, and tissues (Abera et al., 2017). A study of the entire collection of genes within an organism’s genome is known as genomics (NIH, 2022; WHO, 2025). Genomics encompasses aspects of genetics, focusing on the comprehensive characterization of an organism’s entire set of genes rather than on individual genes (Baeza, 2024). The investigation of living organisms has undergone a transformation through the application of genomics and related fields, providing unique insights that enhance various applications aimed at improving human life, economic conditions (Kalaitzandonakes et al., 2023), and environmental sustainability (Mudaliar et al., 2023).
According to a genomic analysis, 80% of the 6,000 rare disorders have genetic causes (Brittain et al., 2017). Cancer, a genetic disease, has revealed through DNA sequencing the mutational events and oncogenic drivers (D. Wang et al., 2023). Genomic tests contribute significantly to the prediction and prevention of diseases, including familial hypercholesterolaemia (FH) (Brittain et al., 2017). Agricultural industries are currently confronting multiple challenges, including global changes in climate (Bai et al., 2024), growing populations (Putri et al., 2019), resource depletion (Feng et al., 2023), reduction of cultivable land (Mirzabaev et al., 2023), and the prevalence of pathogens (Hossain & Roslan, 2023). Advances in genomic technologies, such as DNA sequencing and gene editing, have transformed the field. DNA sequencing includes; Nextgeneration sequencing (NGS) (Marudamuthu et al., 2023), Ribonucleic acid sequencing (RNA-seq) (Upton et al., 2023), whereas, gene editing methods includes; Clustered Regularly Interspaced Short Palindromic Repeat- CRISPR associated protein 9 (CRISPR/ Cas9) (Q. Liu et al., 2021), Transcription activator-like effector nucleases (TALENS) Zinc-finger nucleases (ZNF) (Malzahn et al., 2017) and Oligonucleotide directed mutagenesis (ODM) (Ravikiran et al., 2025) as well as doubled haploids (Chen et al., 2024), molecular markers (Kumar et al., 2024) and mapping populations (Temesgen, 2021), offers potential solutions against such agricultural challenges (Hossain & Roslan, 2023). Genome sequencing techniques are applied to various fields of industrial biotechnology such as; strain development or improvement (Salazar-Cerezo et al., 2023), enzyme discovery (Zaparucha et al., 2018) and analysis of microbial community (Hosokawa et al., 2022). The potential to enhance microbial strains through the incorporation, deletion, or alteration of

Introduction
The eco-friendly and commercially sustainable production has been a crucial aspect of modern commercial development. The ecologically sustainable microbial production of value-added products has seen rapid growth across multiple sectors, such as food, pharmaceuticals, and energy, resulting in notable economic benefits and social advancements on a global scale (Shi et al., 2022). The development of “omics” technologies has aided the improvement of microbial production processes through diverse omics procedures, such as genomics, transcriptomics, metabolomics, and systems biology (Amer and Baidoo, 2021). These omics approaches give important understandings into the widespread metabolic variations, thereby identifying the factors that affect microbial production efficiency and improving the understanding of targeted optimization strategies. The integration of omics approaches is considered essential for any strategies that aim to be industrially sustainable. Industrial activities depend on the cultivation and accessibility of significantly competent microbial species to optimize bioproduct yields (Keasling, 2012). Recent progress in the industrial generation of value-added products heavily depends on strategies rooted in omics. Typically, the industry can achieve cost-effective production of limited quantities of biopharmaceuticals (Harris et al., 2015). Nevertheless, to sustainably scale up production capacities, economically feasible alternatives must be planned, standardised, and developed. Over the past few decades, microbes with enhanced abilities for superior product generation have been identified (Babar et al., 2018; Kim et al., 2015). Latest improvements in metabolic engineering have aided the manipulation of various genetic components, including coding and regulatory regions, to maximize commercial benefits (Babar et al., 2018). Genomic methodologies aim to investigate the variations among individuals at both the germline and somatic levels by sequencing specific genomes. The transition from DNA microarray technology to DNA sequencing has enabled the thorough sequencing of entire genomes, providing a detailed characterization of an organism’s genomic landscape (Dai and Shen, 2022) whereas, transcriptomics involves the analysis of mRNA, microRNAs, long non-coding RNAs, and circular RNAs. The methods used in transcriptomics are designed to identify and enumerate RNA molecules transcribed from a specific genome at a particular time. Proteomics on the other hand focuses on understanding the functional significance of all proteins expressed within a cell, tissue, or organism by examining the flow of information via protein signalling and metabolomics contributed a vital part in the development of bioprocesses by providing a comprehensive overview of metabolic activities (Horgan and Kenny, 2011; Petricoin et al., 2002). Synthetic biology contributes a vital part in the production of high-performance strains for microbial manufacturing. A variety of microorganisms including bacteria, fungi, and microalgae can be employed in microbial production. However, synthetic biology methods primarily emphasis on the balanced blueprint of biosynthetic metabolisms for target outcome, as well as the creation and standardisation of these pathways and the heterologous production of the biosynthetic components (Wan et al., 2023). These approaches include the optimisation of fermentation process, optimisation of medium composition, scale up of fermentation, optimization of cell growth for manufacture of desired product, and strategies to decrease feedback inhibition and product toxicity (Figure 3.1) (Wan et al., 2023; Zhang et al., 2022).

Introduction
Wide range of industrially important products such as antibiotics, vitamins, enzymes, polymers, amino acids, biofuels are produced by microbes in extremely small quantities. Using microbial strains that generate an elevated amount of the intended product is a prerequisite for effective biotechnological procedures at the industrial scale. But since this isn’t an intrinsic feature of the chosen microorganism, changes to their genetic makeup may help to navigate this. Therefore, in order to overproduce the target metabolite and increase process efficiency, industrially relevant microorganisms are exposed to a range of treatments employing physical, chemical, or genetic methods. Thus, microbial strain improvement is the process of improving the biosynthetic capacities of microorganisms to generate the desired product in greater quantities.
Recycling resources and promoting sustainable development have grown in importance in recent years. Cosmetics, food, fuels, lubricants, plastics, drinks, fibres, and medications are just a few of the goods that are being biosynthesised due to the growing popularity of biological production of commercially significant metabolites (Kaur et al., 2012). The rising bioeconomy’s success hinges on our capacity to produce high-performing strains efficiently and economically. One successful strain engineering strategy is the Design–Build– Test–Learn (DBTL) framework. The strain engineering process must be viewed from the perspective of optimising the entire cycle rather than just increasing productivity at each stage, if strain development time and cost is to drastically cut down. We suggest a strategy that incorporates all four phases of the DBTL cycle and leverages the latest developments in phenotyping techniques, high-throughput genome engineering, computational design, and machine learning tools to forecast strain scale-up efficiency. By substituting sustainable alternatives made from renewable feedstock for petroleum-based products and ingredients derived from animals or wild-harvested plants, microbial biomanufacturing of chemicals, materials and biomolecules promises to lower greenhouse gas emissions, enhance land use and promote sustainability. But doing so necessitates creating reliable and effective industrial strains that can generate a variety of goods at reasonable costs. Enhancing the effectiveness of the strain engineering process is necessary to lower development cost, time in order to take advantage of market potential in all bioeconomy industries.
Over the past few decades, technical advancements in genome engineering have significantly boosted our capacity to engineer biological systems. The strain engineering process has been significantly sped and enhanced by synthetic biology methods like as genome editing using CRISPR (clustered

Introduction 
A broad definition of bioprocessing is the process of creating a valuable product from a live source. The system’s most important element is that the source organism is living and sensitive to its surroundings. Accordingly, the framework states that it will respond to relatively small changes in its physico-chemical environment by modifying its physiology to maximise efficiency. The use of entire cells and enzymes to catalyse bioprocesses in industrial settings is becoming more popular these days than conventional chemical synthetic methods. Among the many benefits of biotransformations in this context are their extensive substrate portfolio (including liquid, solid, and gas waste), one-pot reactions in mild circumstances and environmental friendliness. However, a number of drawbacks, including the unstable nature of biocatalysts and subpar performance in specific reaction conditions, the low solubility of some substrates in the reaction medium, substantial production expenses brought on by intricate downstream processing and product isolation and the lack of expertise in microbiology or bioprocess design, frequently make it difficult to scale up bioprocesses from the lab to the manufacturing facility. There is a growing need for innovative bioprocesses that can get over the aforementioned obstacle in industrial and environmental biotechnology in order to create effective, sustainable, and affordable processes. As a result, the industrial sector requires new methods that use biocatalysts that are highly active and stable under a variety of reaction conditions (typically accomplished through metabolic engineering), boost feedstock utilisation by using inexpensive waste resources, use green chemistry solutions that enable the use of fewer toxic solvents and reagents, or develop cost-effective biorefinery concepts that can transform industrial waste and byproducts into products with added value, thereby establishing new value chains. Figure 1.1 shows the three stages of a typical bioprocess: upstream processing, bioreaction and downstream processing which includes separation and purification steps. Every stage of these phases offers multiple chances to enhance a certain bioprocess.

After the Green Revolution, it is now time for an Ever-Green Revolution based on Eco Agriculture or Agroecology. In 2018, the FAO described Agroecology/Eco Agriculture as a means to transform food and agriculture systems by addressing root causes and emphasizing the improvement of efficiency in resource use, conserving, protecting and improving livelihoods, promoting equality and well-being and enhancing the resilience of people, communities and ecosystems. A timely transition to a sustainable eco-agriculture approach is essential to protect food security, the well-being of people and farmers prosperity. Eco Agriculture is a broad term that can inclusively refer to agroecology, regenerative, organic, natural, jaivik, etc, and is increasingly being recognized as the way to help save the planet. While discussing this with Prof Swaminathan and the ICFA team, the idea of a Working Group emerged. When I was requested to form the Eco Agri Working Group through ICFA, I consulted with different sectors and tried to determine the “why” and “how” of the impending Eco Agri Revolution.
WHY
The past sixty years led to Green Revolution and alongwith that ‘success’ several adverse impacts and the changing global situation as noted in Table – 1 are the reasons for the need for an Evergreen Revolution based on Eco Agriculture

It is well recognized that sustainable management and sustainable livelihoods are inseparable. If neglected and if the present trends are not corrected in time, everyone’s future is threated. On the other hand, there is increasing recognition of living examples and demonstrated evidences of how the eco agricultural practices can help provide a solution to some of the major problems of today and tomorrow. Also, the main stream international agencies are emphasizing that agro-ecological approaches are the way forward. What the policy makers, farmers and people would like to know is How !it has been our experience that is most countries of the developing world the answer to ‘How’ of eco-agricultural is being demanded! In January 2016, a global team was invited by the office of Prime Minister of India to discuss and prepare an approach paper on Agro-ecology ( or Eco Agriculture including Organic farming). The team consisted of J. Fagan, Hans Harren, M.H. Mehta and A. Thimmaiah who after intensive discussions had prepared several presentations – first given to the group of top officials of Government of India departments and institutions as organized through the office of the prime minister. This was later followed by a meeting with Prime Minister Modi. During this meeting, the clear question asked was, “You need not convince us that agro ecology and organic farming are the way forward, but the question is how? How do we expand this system to national scale ?”

Agriculture is increasingly being looked through the angle of environment and sustainability now. On global scale, the move is towards a balanced need for food production and ecological factors. Green revolution made a huge contribution for food security but now we face the following challenges.
1. Since the green revolution, land has witnessed an indiscriminate and prolonged use of chemicals and the strong need for moving away to more eco-friendly farming is felt.
2. We need to promote eco technologies which integrate the principles of ecology in technology development and dissemination. We also need to promote production and use of biological software for sustainable agriculture and food security.
Therefore, the terms like Regenerative Agriculture, Nature base solutions, Agro Ecology, Eco Agriculture, Conservation Agriculture, Organic Farming, Holistic Resource Management, Climate Smart Agriculture, Prakrutik Kheti etc etc have been gaining prominence in policy and funding spaces related to food systems. Global policy floors like the UN Food Systems Summit and the UN Climate and biodiversity conferences have used these terms as bywords for Sustainable Development. Different Names – Eco Agriculture Revolution Encompasses all ! Regenerative Agriculture is defined by many in ways that closely resemble Agro Ecology / Eco Agriculture. Broadly it describes farming, ranching and pastoral practices that stabilize our planet’s climate and carbon cycles by rehabilitating organic matter and microbial activity in the soil, thereby increasing carbon storage, retaining moisture and safeguarding bio diversity and living systems.

It is well understood that the impact of climate change on agriculture and food security will be critical. The variation in climate influences the productivity of crops, livestocks and fisheries.
The major points to remember are
Climate changes are increasingly impacting agriculture and food security adversely.
Cereal productivity may decrease by 10 – 40% by 2100.
Negative effect on livestock productivity and increased disease.
Achieving Millennium Development Goals (MDG) will become more difficult.
Further, it is also estimated that : Cost of Climate Change will be equivalent of loosing 5 to 20% of GDP (N. Stern : World Bank).Sustainable Agriculture practice could absorb a third of the CO2. Globally, about 800 m $ / day is spent on direct / indirect subsidies. Among other things, it is suggested that encouraging Eco Agriculture is the way out. We must transform 1.5 b ha into Eco / Agri Farming. Small farmers to play BIG role. At the COP28 summit in Dubai, food and agriculture declaration was signed by over 130 world leaders on Sustainable Agriculture and a commitment to mobilize over $2.5 billion to tackle climate issues related to agriculture
COP and 4 per 1000 initiative
Conference of the Parties (COP) to the UNFCC (United Nations Frame Work on Climate Change) has been making significant efforts to mitigate the adverse climate change efforts. At COP 21 in Paris, a landmark agreement was reached to combat climate change and accelerate actions for sustainable low carbon future. COP 22 at Morocco will focus on short, medium and long

In the last several decades many international forums and institutions have discussed and agreed that food and water security are the most important issues for the future. The damage to the ecology directly affects the food, land, water, health and the livelihood. Agricultural progress serves as the best way to fight poverty, hunger and livelihood problems. Though in the last few decades, billions of pages about hunger, food and water security have been written, thousands of conferences have been organized, the urgency of action plans and creating holistic models is the most important need. For this, we must require bold reforms and action oriented programs which can reach the smallest farmers and give an optimistic signal rather than a despondent picture. Developmental models that are holistic and close to nature, sustainable and based on inclusiveness considering ‘unto the last’ women and man are the need of the day. Land and water together with biodiversity and atmosphere conditions are the foundations for sustainable food security. The ecological damage to these foundations are leading to lowering of productivity and livelihood. This will further aggregate with the threat of climate changes such as temperature, rain falls and sea level rise. As per the exercise by World Food Program, it is indicated that the green revolution states like Punjab and Haryana may become food insecure in another 20 years. Food insecurity is measure in terms of land degradation and salinization, ground water tables and green cover loss. *Based on Key Note address at Global Water Meet for Climate Change Adaptation – Agrarian Perspectives : 24 – 26 OCT. 2016 – UAS – DHARWAD – INDIA
Our Soils
The year 2015 was declared ‘ The International Year of Soil’. This is understandable. A healthy soil is key to farm productivity and healthy life (Annexure – 1). In India, out of 306 m. ha reported under various land uses,

In contrast to the traditional universities, agricultural universities have been entrusted with the Herculean task of technology dissemination at the grass root level such that the package of practices evolved by the agricultural scientists should reach out the end-users, viz. farmers , for adopting in the field, with consequent increment in the farm productivity and farmer’s income. This unique mandate has been assigned to agricultural universities on the pattern of land grant colleges of the United States. Such vision and trust, envisaged by Pandit Jawaharlal Nehru and his devout lieutenants, herald creation of state agricultural universities (SAUs) in the early 1960s. The key role played by SAUs in the first green revolution and agricultural human resources development have been regarded as the milestones in the history of India post-independence, that made the country self-sufficient in food production and, in turn, to self reliance in milk, vegetables, fruits and inland fish production. Today, India has set fourth into commanding position as a global economic power, with primary and secondary sectors, viz. agriculture and industry, contributing modestly. At the current pace of the growth rate, I would not hesitate to predict that by the year 2020, we will accomplish the top lines both in terms of productivity and sustainability, by transforming hitherto deemed liability of population into a formidable asset of human resource capital.
Hunger-free World
Agriculture is a vital development tool for achieving the Millennium Development Goals that call for halving by 2015 the number of people, suffering from extreme poverty and hunger. We also note that more than 50% of the people in the world are small and resource-poor farmers and another 20% rural land less. The challenge is to transform this

To most of us Prof. Swaminathan was a great Scientist, humanist and true global leader. I am blessed to have been associated with Prof. Swaminathan. From a brilliant scholar to a visionary global leader, he had continuously moved to higher and higher level of achievements. The nine decades of his life can be divided in 4 phases – Brilliant & dreamy student, devoted scientist and Science Manager, a visionary and missionary solving the hunger problem and a global citizen and humanist. The vision and drive had taken him to extraordinary heights – Like Maharshi Patanjali has said in Yoga Sutra– “When you are inspired by some great purpose, some extraordinary vision, all your thoughts break their bond. Your mind transcends limitations, your consciousness expands in every direction and you find yourself in a new, great wonderful world.” Among many things, I also recollect his inspiration when I was planning GSFC Science Foundation and later the activities of Gujarat Agricultural University.

“Where is your Dhoti, Dr. Mehta ?” Dr. Varghese Kurien surprised me as I entered his office at IRMA (Institute of Rural Management Anand). That was April 2000, soon after I had taken over as the Vice Chancellor of the erstwhile Gujarat Agricultural University (GAU) and had decided to call on him during my visit to the Anand Campus. (At that time GAU was the largest University in Asia with four main campuses – Dantiwada, Anand, Junagadh and Navsari and about 65 experimental farms / stations spreaded all over). Earlier, I did have some interactions with Dr. Kurien. When at GSFC Ltd., we had introduced Nylon – 6 Engineering plastic. I had discussed with my team of Research and Application Development Engineers about multi layer packaging of dairy products where Nylon – 6 can have a good market potential which we used to discuss with Amul. Also, our work on Bio Fertilizers and Bio Pesticides had indirect interest to them. So, when suddenly I was offered the position of Vice Chancellor of GAU and was in a dilemma, I went for his advice. After all, he had held the same position earlier (in addition to AMUL). I explained about the offer and said that I was not too sure about accepting it. He, on the contrary, encouraged me to accept it saying “you can do a lot !” I just murmured,” But I am not an agriculture graduate. I am a Chemical Engineer!” To which he jokingly said – “So ?. I am a Metallurgical Engineer. And now I am a Dudhwala!”

for limitation of world fresh water supply, farmland availability, salinity ingression and the pressing future need of food supply. The cultivation of salttolerant crops on saline soil and with saline waters has significant social and economic potential. It is often argued that fresh water agriculture near rivers and ponds was invented because of the need to sustain people and communities. Saline water agriculture is going to be needed for sustaining our future generations and civilization.
FROM DESALINATION OF SEA WATER TO SEA WATER AGRICULTURE
Sea water contains nearly 35000 ppm of dissolved salts. There has been great deal of interest world wide on desalination of sea and brackish water to safe drinking water. In early 1960s the young President of USA John Kennedy put forward two famous challenges for the scientists (1) Landing the man on moon and (2) Producing desalinated water at low and competitive cost. It is often said that the first challenge was met but the second one has been more difficult! With tremendous support and interest, work on desalination was taken up worldwide. Newer processes were being tried. At the Environmental Research Lab of University of Arizona and at Central Salt and Marine Chemicals Research Institute, Bhavnagar simultaneously solar powered HD (humidification – dehumidification) process of Desalination was developed and pilot plants were commissioned. It was however realized that desalinated water was costly and not easily applicable to most coastal communities, though for many countries in middle east with no alternative water source and cheap petroleum energy – it is applicable on a very large scale.

The Late Dr. APJ Abdul Kalam is described as a great patriot, visionary leader and the 11th President of India ( 2002 – 2007 ). The country would have celebrated his 84th birth day on 15th October 2015. To many like me, he was the most ideal role model that the youth of India needed, in recent time. He emerged as a complete human-being who touched the lives of people. My first meeting with himwas when he visited IPCL in eighties - as the DRDO Chief to discuss about Carbon Fiber and Composites. I was heading GSFC’s R & D Centre and other facilities like engineering plastic Nylon – 6 and their Composites and hence was invited to join the discussions. That interaction left a strong impression in my mind. Later when I became Vice Chancellor of Gujarat Agricultural University, I had many more opportunities to meet him and was often surprised at his deep rooted interest and knowledge in every sphere of Science & Technology. Subsequently, to my delight, I received an invitationfrom his office on the eve of 26th January evening - at home with the President and later was given more time for a one-to-one meeting the next day. Walking across the corridors of the Rashtrapathi Bhavan, the atmosphere looked rather formal and uneasy for me, but, as I was ushered into his room, I saw Dr. Kalam wearing his favourite blue shirt and smiling. He moved forward and greeted me with the same friendliness and warmth. As we started talking about Agriculture scenario, the work I was planning and the future prospects, I marveled at his understanding and insight and left the room truly inspired. Later, I was fortunate to have many more meetings and interactions with him. In fact, during myfrequent visits to Delhi as the Chairman of National Agri Technology – nrdc, I would call at his residence in the evenings at Rajaji Marg to discuss different developments and get his guidance. It soon became clear to his efficient Secretaries to inform me in advance and arrange a meeting with him whenever he would visit Anand or Vadodara. In one such meeting at theCircuit House in Vadodara, I took my 8 year old Grand Daughteralongwith me. He enquired briefly about the progress in my work in Bio Technology and Agriculture in the first 2 minutes but later turned his entire attention to the little girl. It was amazing the way he interacted and talked with much love and

All agriculture universities have three main Directorates – Education, Research and Extension of the three, I have often observed that Extension Department comes in for maximum criticism. ‘Loose links’ and need to do much more in transfer of knowledge and technology are frequently emphasized at various levels – especially in meetings with farmers groups. This is understandable – as it is said that less than 10% - often less than 6% of lab scale knowledge and development reach the farmers fields in developing countries and even in many ‘developed’ counties. The situation is much more challenging when we consider a large population of small and marginal farmers – who as we saw can play extremely important role in eco-agriculture. A large percent of such farmers – women and men are practicing eco friendly agriculture without realizing it. Their ‘ignorance’ can be converted in to advantage and new opportunity. The age old extension practice of reaching farmers through meetings, visit , seminars, camps, demonstrations all have limitations and need to be ‘scaled up’. New developments in information and communication Technology offer a great opportunity for a big jump in reaching the unreached. Again to alarge population of ‘Green Revolution’ – there is a new hope and opportunity.
ICT in Agriculture
The potential for using ICT in agriculture can be divided broadly under two heads (1) as a tool for direct contribution to agricultural productivity and (2) as an empowering tool for the farmer to take and quality decisions. There have been several excellent examples of practical use of ICT in Agriculture and expectations are rising such that a major transformation

Rivers are the most important system for water, for irrigation and human settlement. Historically, civilizations always nucleated near rivers, and latter also had social and religious significance. Rivers in India are considered holy and play the most important part in the lives of people, fauna & flora and the future environmental system. The Ganga Basin is the largest river basin in India which includes the Ganga, the Yamuna, the Ghagra, the Gandak, the Kaveribasin etc. Compared to these, the Vishwamitri River, situated between Mahi River in North and Narmada River in South in Central Gujarat is a small seasonal river but it is very important for the city of Vadodara and Central Gujarat region. This seasonal river originates from Pavagadh hills and flows east to west. It is a typical small river with the kind of problems in most rivers in India and other countries – liquid and solid wastes, enouncements, blocking of water ways, floods in monsoon months and dry dumping basin during most other months etc.
RIVERS & THEIR REVIVAL
River basin planning and watershed management were the centerpieces of water resource planning at the dawn of the era. For most of the century, however, natural resource policies and pressures led to watershed degradation. Today, the resources value of watershed ecosystems are being rediscovered. Watershed management reflects the recognition that we can only sustain biodiversity by managing the future ecosystem.
VISHWAMITRI RIVER
In a well researched book ‘Vishwamitri Mahatmyam’ edited by Thaker of oriental Institute – Vadodara the history, glory and mythological details of the ancient river Vishwamitri has been brought out. It is said that the river

Bioshields offer barriers of vegetation, shrubs, small and big trees and if integrated as a well designed system they can greatly help our coastal as well as inland areas. Though primarily looked at for coastal regions, under a broader definition Bioshields can play important role in semi-desert areas, hills, etc. also.
Why Bioshield ?
Bioshields or Biobarriers can make a major contribution in minimizing the effects of storms, cyclones and Tsunamis and at the same time offer short and long term ecological and livelihood benefits.
• Bio-Shields in coastal areas include raising mangroves, casurina, palms, bamboo & other tree species and halophytes like Salicornia, etc. followed by other regular plants for the land.
• They serve as speed-breakers under conditions of coastal storms, cyclones and tsunami.
• In addition, they serve as carbon sinks, since they help to enhance carbon sequestration and sustainable fisheries and agriculture.
• Integration of Bio-shield with livelihood options and eco-restoration by developing different site specific models is therefore very important.
For example- the case of two villages near Kalpakkam in Tamil Nadu is often taken. During the devastating Tsunami sometime back, the village with plantation- a natural bioshield was saved with hardly any loss of life as against a nearby village with no natural bioshield. Several such examples are available world over. This indicates that if we can have a good, scientifically designed bioshield, it can be of a great help. This concept is bound to get much greater emphasis when we consider the increasing effect and danger due to climate change in the coming years.

The recent earthquake in Nepal brings back memories of 26th January 2001. While the nation was busy in celebrating Republic Day, an earthquake shattered Gujarat especially Kutch and Saurashtra regions. A large number of buildings and houses collapsed within moments. Thousands were injured and many lost their lives and many more became homeless.
