[EBOOK] Opportunities and challenges for research on food and nutrition security and agriculture in Europe, By EASAC

National academies of science have a long tradition of engaging widely to strengthen the evidence base to underpin the delivery of enhanced food and nutrition security at regional and national levels. EASAC, the European Academies' Science Advisory Council, has produced this report for European audiences as a contribution to a project worldwide initiated by IAP, the InterAcademy Partnership, the global network of science academies. The IAP work brings together regional perspectives in parallel from Africa. Asia, the Americas and Europe on the opportunities for the science-policy interface, identifying how research can contribute to resolving challenges for agriculture, food systems and nutrition.

Our EASAC report combines analysis of the current status in Europe with exploration of ways forward. Overconsumption of calorie-dense foods leading to overweight and obesity creates a major public health problem in Europe; but Europeans are not immune from other concerns about food and nutrition security and must also recognise the impact of their activities on the rest of the world. We define the goal of food and nutrition security as providing access for all to a healthy and affordable diet that is environmentally sustainable. We recognise the necessity to take account of diversity: in food systems and dietary intakes within and between countries, and in the variability of nuưient requirements in vulnerable groups within populations and across the individual's life cycle.

In our report we take an integrative food systems approach to cover inter-related issues for resource efficiency, environmental stability, resilience and the public health agenda, also addressing issues for local-global interconnectedness of systems. Setting priorities for increasing agricultural production through sustainable intensification must take account of pressures on other critical natural resources, particularly water, soil and energy, and the continuing need to avoid further loss in ecosystem biodiversity. Dealing with food and nutrition security must include both supply-side and demand-side issues: reducing food waste and changing to healthier consumption patterns will reduce pressure on land and other resources.

The United Nations Sustainable Development Goals and Convention on Climate Change objectives provide critically important general frameworks for meeting the challenges to food and nutrition security but mandate renewed engagement by science to clarify trade-offs among goals and address the complexities of evidence-based policies and programmes. For example, it is becoming dearer that climate change will have negative impacts on food systems in various ways, necessitating the introduction of climate-smart agriculture (such as
the adoption of plant breeding innovations to cope with drought) but also that agriculture itself contributes substantially to climate change Mitigating this contribution depends on climate-smart food systems (such as land-sparing and agronomic management practices) together with efforts to influence consumer behaviours associated with excessive agricultural greenhouse gas emissions (overconsumption of calories and high meat intake). Therefore, taking account of the accruing scientific evidence, changing dietary consumption could bring co-benefits to health and to climate change.

In our report we have focused on scientific opportunities: how the current scientific evidence base can shape understanding of challenges by the public, serve as a resource for innovation, and inform policy options, and what the research agenda should be to fill current knowledge gaps. It is urgent to continue to build critical mass in research and innovation and to mobilise that resource in advising policymakers and other stakeholders. We emphasise the vitally important role of basic research in characterising new frontiers in science and of long-term commitment to investing in research to enable, establish and evaluate innovation. This innovation must encompass social and institutional, as well as technological, innovation.

We frame our specific recommendations within die context of strategic dimensions that determine a wide range of actions in science and policy:

•    The interfaces between research on the nutrition-sensitivity of food and agriculture systems and on environmental sustainability must be addressed to connect scientific knowledge on natural resources to the food value chain. The sustainable bioeconomy and circular economy provide for new overarching frameworks, going beyond traditional concepts of economic sectors.

•    The focus cannot be only on populations in general but should also cover particular issues for vulnerable groups such as mothers and children, the elderly, patients and migrants. This requires systematic, longitudinal data collection to generate robust resources, together with cross-disciplinary research, encompassing economics and social sciences as well as the natural sciences, to understand vulnerable groups and the more general aspects of consumer behaviour.

•    Large data sets, based on comparable and verifiable methodology, are a vital tool to support innovation throughout the food system and to prepare for risk and uncertainty. There is much to be done to fill data gaps, to agree improved procedures for data collection, curation, analysis and sharing, while also addressing data ownership and privacy concerns.

•    To contribute with evidence to options for reform of the present Common Agricultural Policy (CAP) towards devising a European Union (EU) food and nutrition policy that rewards innovation, reduces risks, focusses on public goods, takes account of the varying national interests and cultures, and contributes to benefitting the rest of the world.

•    EU development assistance should be viewed broadly, to include international collaborative research; research in the EU on prionties for global food systems, their resilience and perturbations; sharing of science and technology especially related to food and nutrition security; and resolution

of international governance issues of food and agriculture.

•    Ensuring that regulatory and management frameworks are evidence-based, proportionate and sufficiently flexible to prepare for and enable advances in science.

Within this overall framework for European strategy

development, our report identifies many opportunities

to generate, connect and use research. Among specific

scientific opportunities are the following.

Nutrition, food choices and food safety

•    Understanding the drivers of dietary choices, consumer demand and how to inform and change behaviour, including acceptance of innovative foods and innovative diets.

•    Tackling the perverse price incentives to consume high-calorie diets and introducing new incentives for healthy nutrition.

•    Clarifying what is a sustainable, healthy diet and how to measure sustainability related to consumption.

•    Exploring individual responsiveness to nutrition and the links to health.

•    Promoting research interfaces between nutrition, food science and technology, the public sector and industry.

•    Evaluating how to make food systems more nutrition-sensitive.

•    Characterising sources of food contamination and the opportunities for reducing food safety concerns
that may arise from implementation of other policy objectives (for example, the circular economy goal of recycling of waste materials).

•    Compiling analytical tests to authenticate food origin and quality.

•    Assessing any disconnects between the implications of the 2015 United Nations Climate Change Conference (COP21) objectives for livestock and meat consumption, and standard recommendations for consuming healthy diets.

Plants and animals in agriculture

•    For livestock, determining how to capitalise on genomics research for food production and for animal health and welfare. This includes the rapidly advancing science of genome editing and the increasing significance of charaơerising genetic material conserved in gene banks.

•    For the oceans, improving the knowledge base for sustainable harvest and culturing of lower trophic level marine resources and exploring the potential for biomass provision to diminish pressures on agricultural land, freshwater and fertilisers.

•    For crops, progressing understanding of the genetics and metabolomics of plant product quality. This also includes capitalising on the new opportunities coming within range for the targeted modification of crops using genome editing.

•    For plants as for animal science, it is important to protect wild gene pools and to continue sequencing of genetic resources to unveil the potential of genetic resources.

Environmental sustainability

•    Evaluating climate resilience throughout food systems and transforming food systems to mitigate their global warming impact.

•    Capitalising on opportunities to co-design research across disciplines to understand better the nexus food-water-other ecosystem services and to inform the better coordination of relevant policy instruments, including the CAP, Water Framework Directive and the Habitats Directive. Efforts to increase the efficiency of food systems should not focus on increasing agricultural productivity by ignoring environmental costs.

•    Developing an evidence base to underpin land and water use in providing the range of private and public goods required in a sustainable way, appropriate to place.

Regarding biofuel choices, the immediate research objectives for the next generation of biofuels include examining the potential of cellulosic raw materials.

•    Research should continue to explore the value of synthetic biology and other approaches to engineer systems with improved photosynthesis. There is also continuing need for research to clarify impacts of biomass production on land use and food prices.

•    For soil, expanding research to understand and quantify the potential value of soil in carbon sequesưation and, hence, climate change mitigation. There is a broad research agenda to characterise other functions of soil and the soil microbiome and contribute to the bioeconomy, for example as a source of novel antibiotics. Research is also important to support cost-effective soil monitoring and management, particularly to underpin the reduced use of fertilisers and improve biodiversity.

Waste

•    Committing to the collection of more robust data on the extent of waste in food systems and the effectiveness of interventions to reduce waste at local and regional levels.

•    Ensuring the application of food science and technology and agronomy in novel approaches to processing food and reducing waste, and

in informing the intersection between circular economy and bioeconomy policy objectives.

Trade and markets

•    Increasing commitment to data colleơion on trade flows and prices with modelling and analysis of databases.
•    Examining linkages between extreme events and price volatility, evaluating the effects of regulatory policy instruments in agricultural commodity markets and the price transmission between global commodity markets and local food systems.

•    Ascertaining the science agenda for understanding the characteristics of fair trade systems, for example the non-tariff conditions associated with variation in regulatory policy, labelling or other food safety requirements.

Innovation trends

In each of the above-mentioned specific areas of science opportunities, the linkages between basic science and problem-solving applied science seem likely to become more closely related in the future. This is so in the fields of biosciences, digitisation, mathematics and farm precision technologies, health and behaviour, as well as in complex environmental and food system modelling. This has consequences for the redesign of the science landscape and for science teaching and the training of next-generation scientists to address food, nutrition and agriculture issues.

We emphasise the key role of agricultural sciences for European competitiveness and urge a rebalancing of commitments: to shift budget items from agricultural subsidies towards innovation in the pending reform of the CAP.

It is now important to be more ambitious in identifying and using the scientific opportunities. Our messages are aimed at European and national policymakers, member academies, the scientific community and other stakeholders. We will also use this analysis of European evidence as the regional contribution to the IAP integrated phase of the project, to develop interregional and global recommendations.

[EBOOK] Biochar Systems for Smallholders in Developing Countries (Leveraging Current Knowledge and Exploring Future Potential for Climate-Smart Agriculture), Sebastian M. Scholz et al., Published by THE WORLD BANK

Three of the biggest challenges of the twenty-first century are the need to nearly double food production by 2050, to adapt and build resilience to a more and more challenging climatic environment, and to simultaneously achieve a substantial reduction in atmospheric greenhouse gas concentrations. The surge of interest in climate-smart agriculture, which focuses on solutions to the three challenges, has sparked curiosity in using biochar as a tool to fight climate change while also improving soil fertility. Biochar systems are particularly relevant in developing country' contexts and could be leveraged to address global challenges associated with food production and climate change. However the potential effects of biochar application to soils are diverse and its climate impact is contingent on the design of the system into which it is integrated. 'Hius biochar systems are inherently complex and further research is needed to understand their associated opportunities and risks in developing countries.

There are a number of reasons why biochar systems might be particularly relevant in developing-country contexts. The potential for biochar to improve soil fertility' could result in increased crop yields from previously degraded soils for smallholder farmers. Improved cookstoves that produce biochar as well as heat for cooking could reduce indoor aữ pollution and time spent on fuel gathering. Both of these results could be beneficial to forests. Enhanced food production capacity could potentially decrease the need to clear more forested land for agriculture, and more efficient cookstoves could decrease wood gathering from forests already in decline. It is vital that further research is undertaken to fill the gaps in our knowledge of biochar systems.

This report offers a review of what is known about opportunities and risks of biochar systems including soil and agricultural impacts, climate change impacts, social impacts, and competing uses of biomass. The report benefited from its wide-ranging methodology including a desk review of existing literature; a two-step survey of biochar systems that elicited 154 responses to the initial survey, and 48 responses on the follow-up survey to learn more about the social and cultural barriers to biochar adoption; an expert workshop in Washington, DC to assist in analysis of the collected data; development of a typology of biochar systems; and a life-cycle assessment of selected systems in Kenya, Vietnam, and Senegal.

[EBOOK] FRIENDS OF THE RICE FARMER: Helpful Insects, Spiders, and Pathogens, B.M. Shepard, A.T. Barrion and J.A. Litsinger, IRRI

This booklet illustrates representative examples of some of the more common species of predators, parasites, and diseases of insect pests of rice. It can be used with the IRRI booklet Field problems of tropical rice, which provides information only on pest species.

Before intelligent decisions about pesticide applications can be made, it is necessary to be able to identify which insect species are pests and which are beneficial. The occurrence of beneficial organisms varies depending upon location, time of year, and crop cultural practices. Thus we made no attempt to rank the groups by their relative importance.

Scientific language has been minimized so that the descriptions can be more easily understood. The pictures will provide an easy way of identifying beneficial species and thereby help prevent unnecessary chemical treatments.

Like Field Problems, this booklet was designed to facilitate its easy and inexpensive translation and copublication in languages other than English. IRRl does not ask for payment of royalties or payments for translation of IRRl materials published in developing nations. For details, contact the Communication and Publications Department, International Rice Research Institute, PO Box 933, Manila Philippines.

[EBOOK] SOIL BIOLOGY - Advanced Techniques in Soil Microbiology, Ajit Varma and Ralf Oelmuller, Published by Springer

There is general belief and admission that important, innovative and novel ideas emerge over a cup of ‘Indian Darjeeling tea’ or a glass of ‘German beer’. The editors of this book were sipping a cup of tea on the lush green garden lawns of North Maharastra University, Jalgaon, India. The weather was congenial and most suitable for materializations of original ideas. The genesis of this book underlines the concept developed in 2006.

The field of microbiology began concurrently with the discovery of microorganisms by two Fellows of The Royal Society, Robert Hooke and Antony van Leeuwenhoek, during the period 1665-1683. Later, during the golden era of microbiology, noted scientists Louis Pasteur and Robert Koch laid a sound foundation for the modern microbiology. The study of microorganisms has became a valuable science in the last 100 years as it has provided both the means to control a number of infectious diseases and the experimental systems for the development of molecular biology. New developments in biotechnology and environmental microbiology signify that microbiology will continue to be an exciting field of study in the future. Various modern tools and techniques are required for a proper understanding of the roles of microbes in the causation of infectious diseases and the recycling of chemical elements in the biosphere. Assorted laboratory experiments not only motivate researchers and students by stimulating interest and enjoyment but also enhance the acquisition of scientific knowledge along with the development of ‘scientific attitudes’, such as open-mindedness and objectivity.

There are numerous textbooks and review papers dealing with state-of-the-art of various aspects of molecular biology of microorganisms. However, the readers get lost in initiating the experiments due to lack of suitable and easy protocols. They have to search for diverse methods and techniques in a variety of literature and journals and still do not obtain the complete information dealing with the protocols in a concise manner. This book is an attempt to overcome the inherent cumbersome search process. Every effort was made to present the protocols in a very simple manner for easy understanding of undergraduate, graduates, postgraduates, post doctorates, active scientists and researchers.

Soil, the main contributor to plant nourishment, is the top layer of the Earth’s surface and consists of rock and mineral particles mixed with organic matter. Soil microbiology is the study of the microorganisms in soil, their functions, and the consequences of their activities on the nature of the soil and the effect on the growth and health of plant life. Just a few grams of soil, less than a teaspoonful, may contain hundreds of millions to billions of microbes. Not only is the total number of microorganisms in fertile soil quite high, but also, together, they weigh a lot. Soil microbial biomass can range from several hundred to thousands of pounds per acre.

The most plentiful microbes in soil are one-celled bacteria and fungi, which produce long, slender strings of cells called filaments or hyphae. The actinomy-cetes come between these two organisms. It is the actinomycetes that give soil its characteristic earthy smell. In this volume, the editors have accumulated various advanced molecular approaches for studying the different soil microorganisms for the benefit of humankind. Different techniques for measuring microbial biomass and activity in soil have been developed. Primers in Random Amplified Polymorphic DNA (RAPD) techniques for species identification and other forgotten tools like quantitative histochemistry are discussed in details in this book with the hope that this would promote the understanding of microbes by students and advanced researchers alike.

The editors have brought together the diverse topics related to various aspects of molecular approaches to the detection of soil microbes, namely assessing and detecting soil micro-fungal diversity and providing insight into their feasibility. Various problems associated with the dilution plating technique, importance of the rDNA gene in fungal systematics, the reliability of other molecular approaches (especially Denaturing Gradient Gel Electrophoresis) and their drawbacks are discussed. Various modern tools and techniques like automated fluorescent DNA sequencing strategy, mRNA quantitation using real time PGR, RNAi technology, transcriptome analysis and immuno-techniques are handled by subject experts of these specific fields for clear and easy understanding for all. Different widely used methods like fatty acid methylester (FAME), phospholipid fatty acid (PLFA) analyses and denaturing gradient gel electrophoresis (DGGE) are elucidated with their advantages and limitations outlined. DGGE and RISA protocols for microbial community analysis in soil are also one of the highlights of this book.

The soil zone located in and around the active roots is called the rhizosphere. This zone has high microbial activity. Materials released from roots, called exudates, create a food-rich environment for the growth of microorganisms. Rhi-zosphere microorganisms in turn help plants by fixing nitrogen from the soil air, dissolving soil minerals and decomposing organic matter, all of which allow roots to obtain essential nutrients. Plant-Growth-Promoting Rhizobacteria (PGPRs) generate a variety of chemicals that stimulate plant growth. The bacteria grow and persist in the rhizosphere of non-woody roots. Various screening methods for PGPRs are described in this book.

A special kind of fungus called mycorrhizae also associates with higher plants. By colonizing large areas of roots and reaching out into the soil, mycorrhizae assist in transport of soil nutrients and water into the plant. The latest methods for conducting experiments and research in mycorrhiza have been described. Cultivation of a group of mycorrhiza-like fungi belonging to family Sebacinales is enumerated. One of the members of Sebacinales which provides stress tolerance activity against heavy metals and induced pathogen resistance in cereals is discussed.

Authors have brought forth diverse approaches and methods to study the mechanisms behind the observed pathogen resistance induced by Piriformos-pora indica.

Model organism A. thallium was used as the plant partner to understand the molecular basis for beneficial plant/microbe interactions and this is also discussed in this edition. Several other techniques like ion cyclotron resonance Fourier transform mass spectrometry (ICR-FT/MS) for non-targeted metabo-lomics of molecular interactions in the rhizosphere are presented. Immuno-technology for the localization of acid phosphatase using native gel bands in p. itidica and other soil microorganism are elaborated in this volume of the Soil Biology series.

We are grateful to the many people who helped to bring this volume to light. We wish to thank Dr. Dieter Czeschlik and Dr. Jutta Lindenborn, Springer Heidelberg, for generous assistance and patience in finalizing the volume. Finally, specific thanks go to our families, immediate, and extended, not forgetting those who have passed away, for their support or their incentives in putting everything together. Ajit Varma in particular is very thankful to Dr. Ashok K. Chauhan, Founder President of the Ritnand Balved Fducation Foundation (an umbrella organization of Amity Institutions), New Delhi, for the kind support and constant encouragement received. Special thanks are due to my esteemed friend and well-wisher Professor Dr. Sunil Saran, Director General, Amity Institute of Biotechnology and Adviser to Founder President, Amity Universe, all faculty colleagues Drs.

[EBOOK] ILLUSTRATED GUIDE TO INTEGRATED PESTMANAGEMENT IN RICE IN TROPICAL ASIA, W. H. Reissig, E. A. Heinrichs, J. A. Litsinger, K. Moody, L. Fiedler, T. W. Mew, and A.T. Barrion, IRRI

In the past, farmers in tropical Asia grew traditional rice cultivars and either relied primarily on cultural, mechanical, and physical methods of pest control or practiced no pest control. Pesticide application was limited because the yield potential of traditional varieties was too low to justify additional investments. Although pests destroyed part of each crop, severe outbreaks or epidemics were rare.

The widespread introduction of high-yielding rice cultivars in Asia in the last two decades and the associated changes in production practices have improved conditions for insects, diseases, weeds, and rodents. The higher yield potential of the new rices also made increased pesticide application economically attractive to farmers.

The replacement of traditional control methods by pesticides could increase hazards to nontarget organisms, however, and lead to the development of pesticide resistance and environmental contamination. To minimize such problems, Asian farmers must again diversify their pest control practices — a strategy that scientists now term integrated pest management (IPM).

Recently, scientists working in national rice production programs and at international agricultural research centers have written extensively about IPM for tropical rice. Many of the publications are research-oriented, fragmented, and too technical for nonscientists. Furthermore, much of the highly specialized information often focuses on a single species or a small group of pests.

This publication provides practical and comprehensive information to IPM workers in rice fields throughout tropical Asia. It briefly discusses rice plant structure and growth stages and stresses their relation to pest management. There are separate sections on cultural control of rice pests, resistant rice varieties, natural enemies of rice insect pests, and pesticides. The biology and management of the major groups of rice pests — insects, diseases, weeds, and rodents — are discussed in separate sections. Finally, integrated control measures for the entire rice pest complex and the implementation of IPM strategies at the farmer level are described.

This volume represents the combined efforts of many persons. The style and first draft of the text were developed by W. H. Reissig of the New York Agricultural Experiment Station, Geneva, New York, USA, during a 1979-80 sabbatic leave at IRRI. Reissig's firsthand experience in developing IPM strategies for farmers gave him the necessary background to organize the information in a useful form. E. A. Heinrichs, IRRl entomologist, reviewed the technical material and worked with IRRl editors and artists after Reissig's departure.

J. A. Litsinger, IRRl cropping systems entomologist, provided technical information on the biology and management of many insect pests and composed the section on cultural control. K. Moody, IRRl agronomist, supplied technical information and reviewed the section on biology and control of weeds. L. A. Fiedler, a research biologist from the Denver Wildlife Research Center, stationed at the National Crop Protection Center, University of the Philippines at Los Banos, acted as technical consultant in the preparation of the section on Biology and Management of Riceland Rats in Southeast Asia. T. W. Mew, IRRI plant pathologist, provided technical information and reviewed the section on disease management. A. T. Barrion, IRRl entomology department senior research assistant, served as technical consultant and worked with artists in the preparation of the section on Natural Enemies of Rice Insect Pests.

This volume can be easily translated into the various languages of Southeast Asia and serve as a key source of information for IPM training programs. We hope that it will stimulate the implementation of IPM technology by rice farmers in tropical Asia as well as the development of similar publications for other rice-growing regions.

[EBOOK] Info ROOT VEGETABLES (Field and postharvest machinery and materials)

Measured in planted area, onions are the second crop in Germany, after asparagus and close over carrots (11293 ha in 2017). Yearly production is about 500.0001.

Planting starts in March/April and the produce is cropped between August and October. Being a product of easy storage - over seven months -, consumption can be regulated along the year.

In spite of that, domestic production does not cover consumption. Between 2012 and 2016, average yearly imports amounted to 238.0001.

Another fact conditions the onion market in Germany. As a matter of fact, there are two markets in the country. Sweet onions, which have a good caliber and a soft taste, do not grow in Central Europe and must be imported all year round. From Mediterranean countries - mostly Spain - or from the Southern hemisphere in the offseason. Domestic produce ("Haushaltware") with much intense taste can be stored. In spite of that, in a long storage organoleptic properties spoil. New Zealand becomes then an important supplier. Its produce is on the market between March and July. Spanish produce is all year round available, even when it also suffers when submitted to long storage periods.

In spite of those complexities, the good storage characteristics of the onions help to keep the German market somehow stable all year round.

[EBOOK] Plant Pathogens and Principles of Plant Pathology-ICAR e-Course For B.Sc (Agriculture) and B.Tech (Agriculture)

Lecture 01 - Introduction

Definition and History of Plant Pathology

Plant Pathology

Plant pathology or phytopathology is the science, which deals with the plant diseases. It is concerned with health and productivity of growing plants. Phytopathology ( Greek Phyton = plant + pathos - disease, ailments + logos = discourse, knowledge) is the branch of agricultural, botanical or biological science which deals with the cause, etiology (aetiology), resulting in losses and management methods of plant diseases.

Plant pathology can also be defined as the study of the nature, cause and prevention of plant diseases. Plant pathology is related to most of the old and new sciences like biology, physics, chemistry, physiology, mathematics, genetics, soil science, biochemistry, biotechnology etc. Plant pathology has the following major objectives.

1. To study biotic (living), mesobiotic and abiotic (non-living and environmental) causes of diseases or disorders

2. To study the mechanisms of disease development by pathogens

3. To study the plant (host)-pathogen interaction in relation to environment

4. To develop methods of management of plant diseases

Plant diseases

Plant diseases are recognized by the symptoms (external or internal) produced by them or by sick appearance of the plant. The term plant disease signifies the condition of the plant due to disease or cause of the disease. Plant disease is mainly defined in terms of the damage caused to the plant or to its organ. The other definitions for the term disease are:

1. Disease is a malfunctioning process that is caused by continuous irritation, which results in some suffering producing symptoms. This definition is accepted by both American Phytopathological Society and British Mycological Society.

2. Disease is an alteration in one or more of the ordered sequential series of physiological processes culminating in a loss of coordination of energy utilization in a plant as a result of the continuous irritation from the presence or absence of some factor or agent.

3. A plant is said to be ‘diseased’ when there is a harmful deviation from normal functioning of physiological process (Federation of British Plant Pathologists, 1973).

4. The disease can also be defined as 'any disturbance brought about by a living entity or non-living agents or environmental factors which interfere with manufacture, translocation or utilization of food, mineral nutrients and water in such a way that the affected plant changes in appearance with or without much loss in yield than that of a normal healthy plant of the same variety. In general disease is an interaction among the host, parasite and the environment.

Man became painfully aware of plant diseases in the early times of antiquity. This is evidenced by the inclusion of blasting and mildew in the Old Testament. Our ancient religious literature gives informations on plant diseases much before their mention by the Greek philosopher, Theophrastus. Rigveda, Atharvanaveda (1500-500 B.C.), the Artha Shashtra of Kautilya (321-186 B.C.), Sushrute Samhita (200-500 A.D.), Vishnu Puran (500 A.D.),

Agnipuran (500-700 A.D.) and Vishnudharmottar (500-700 A.D.) are some of the ancient books from India where diseases and other enemies of plants are mentioned. In Rigveda, classification of plant diseases and germ theory of disease were discussed.

The learned men during Vedic period were aware that the diseases are caused by microbes. The book "Vraksha Ayurveda" written by Surapal in ancient India contained information on plant diseases. This is the Indian book, which gave first information on plant diseases. He divided plant diseases into two groups viz., internal and external. Plant diseases like rust, smut, downy mildew, powdery mildew and blight were mentioned in the Bible.

The Greek Philosopher, Theophrastus (370-286 B.C.) was the first to study and write about the diseases of trees, cereals and legumes. In his book 'Enquiry into plants' Theophrastus has recorded his observations, imaginations and experiences but they were not based on any experiments. He had mentioned that plants of different groups have different diseases, which are autonomous or spontaneous i.e., no external causes were associated with the plant diseases. The history in several aspects of plant pathology is given as below.

[EBOOK] IAS RESEARCH HIGHLIGHTS, DR. BUI CHI BUU ET AL., IAS (Institute of Agricultural Science for Southern Vietnam)

The Institute of Agricultural Sciences for Southern Vietnam (IAS) is an institution that performs experimental research projects for development of agricultural scientific technology, propagation of newly developed scientific technology, varieties, farming technology education for Southern Vietnam. In 2007, there were a lot of chance and threat, a turning point for much of the country, when Vietnam became a 150th WTO member. Although several casual disasters as flooding and typhoons, brown plant hopper outbreak with virus disease transmission, bird flu, serious porcine reproductive and respiratory syndrome virus disease (PRRSV), volatile world prices on fuel and fertilizer; agricultural production In the country was remarkably higher than the previous year. It not only ensured food security but was also among the 10 key exports to earn revenue of more than $1 billion.

Total export value In agriculture eorned SI 2.5 billion (increasing 18%) including agricultural products of $8.7 billion, and aqua-products of $3.8 billion. Rice export has earned $1.46 billion, with 4.5 million tons - increasing 1 3 9% of value, reducing 3.1 % of quantity as compared to 2006. Fruit-vegetable export gained $299 million.

Farmer Income in 2006 offered VND 26.1 million / household; today gained VND 29-30 million / household in 2007.

Ministry of Agriculture and Rural Development (MARD) has overhauled its policies to boost agricultural productivity, quality and production, and then transform rural Vietnam through a new economic system. This means quicken the transformation of agricultural production by increasing the ratio of industry and services.

For Southern parts of Vietnam (Mekong Delta and South-East regions), agricultural value increased 3.04% including 2.25% for crop production, 6.23% for husbandry, 2.67% for service, 0.8% for forestry. Rice production in Dong Xuan, He Thu, Thu Dong and Monsoon seasons has obtained 9.62million tons, 7.76 million tons, 1.07 million tons, and 2.13 million tons, respectively. The total rice production in 2007 gained 20.6 million tons (augmenting 701,088 t), with growing areas of 4.13 million ha (reducing 77,754 ha), and average yield 4.98 t / ha (increasing 0.26 t /ha).

Rubber areas covered 516,000 ho ( + 5%). Its latex production obtained 550,000T ( + 8%). Its export value was $547.3 million ( + 5.8%) with 291,000 T. Tea areas covered 120,000 ha. Its production gained 540,000 T (+ 6,000T). Its export value was $ 44 million (+ 0.9%) with 47,000 T (+ 7.4%). Cashew nut areas covered 340,000 ha. Its production gained 260,000 T. Its export value was $ 258 million (+ 1 7.8%). Fruit tree areas covered 780,000 ha. Estimated total production would be 7 million tons In this year. Pig population reduced 384,000 heads due to animal foot and mouth disease and porcine reproductive and respiratory syndrome. Cattle increased 4-5% except buffalo reduced 1 -2%. Poultry increased 3-4%.

We have learned In 2007 that looking into the future is risky. Furthermore, In the era of limitless competition with the collapse of trading barrier between countries, IAS must be endeavoring to fully perform its role of progressing among agricultural industrialization, farmer intellectualization and rural civilization as "Three Nongs" vision by MARD (three Nongs including: agriculture, farmer, and rural development).

Seventeen new technologies by IAS have been approved and released in 2007.

We are concentrating on improvement of productivity of agricultural industry and development of environmental-friendly agricultural technology to enable harmonious co-existence of human being and natural ecosystem.

We are endeavoring to establish livestock farming that is well harmonized with environment under tropical conditions, to raise the safety level through stabilized stock and elevation of product quality, to prevent livestock disease in advance through system of continuous quarantine.

We are propagating highly pure and superior seeds such as disease-free tomato seedlings, rice, black pepper, maize, soybean, mungbean, peanut, cassava.

Coping with climate change, IAS deals with studying the effect of climate on crops and animals in Southern parts, especially rice production, with the emphasis on examining increased C02 and temperature impacts. The direct and Indirect consequences for agricultural production have to be assessed to develop strategies and technologies to adapt major crops and animals to changing climate. We need to explore cropmanagement practices that reduce greenhouse gas emission under intensive production, and to prevent from soil degradation and desertification in South-East regions and Central Coastal areas. Others deal with modeling climate change impacts on agricultural production through international cooperation projects, which will be well considered. Because climate change has recently received enormous attention in the media and in policy statements.

MARD actually sees plant breeding and animal breeding at the heart of improvement in agricultural production in Vietnam, the efficiency of adaptive measures can be greatly increased by other efforts, Including molecular marker techniques to speed up the breeding process, geographic analysis of vulnerable regions, site-specific adjustment in crop management as planting dates, water saving. Research Into disease and pest management is crucial for reducing poverty and providing food security in developing countries such as Vietnam. An Important subset of the research is concerned with containment of pests and diseases - otherwise known as bio-securlty.

IAS determines Its function under new situations as a multidisciplinary and specific research institution so that how to integrate between crop science and animal one Into special working groups. Teamwork models are recommended to crucially enhance the IAS's research activities, which meet the demand of agricultural production in South.

The IAS operates as part of MARD's national and International development cooperation programs, with a mission to achieve more productive and sustainable agricultural systems, for benefit of Vietnam. Any your kind cooperation would be appreciated.

[EBOOK] GREENHOUSE TECHNOLOGY AND MANAGEMENT, K. Radha Manohar and C. Igathinathane, Published by BSP (BS Publications)

After the advent of green revolution, more emphasis is laid on the quality of the product along with the quantity of production to meet the ever-growing food requirements. Both these demands can be met when the environment for the plant growlh is suitably controlled. The need to protect the crops against unfavourable environmental conditions led to the development of protected agriculture. Greenhouse is the most practical method of achieving the objectives of protected agriculture, where the natural environment is modified by using sound engineering principles to achieve optimum plant growth and yields. In this chapter, the history, the phenomenon of greenhouse effect and advantages of greenhouses are discussed.

A greenhouse is a framed or an inflated structure covered with a transparent or translucent material in W'hich crops could be grown under the conditions of at least partially controlled environment and which is large enough to permit persons to work within it to carry out cultural operations.

The growing of off-season cucumbers under transparent stone for Emperor Tiberius, in the first century, is the earliest reported protected agriculture. The technology was rarefy employed during the next 1500 years. In the 16th century, glass lanterns* bell jars and hot beds covered with glass were used to protect horticultural crops against cold. In the 17th century, low portable wooden frames covered with an oiled translucent paper were used to warm the plant environment.

In Japan, straw mats were used in combination with oil paper to protect crops from the severe environmental conditions. Greenhouses in France and England during the same century wefe heated by manure and covered with glass panes. The first greenhouse in the 1700s used glass on one side only as a sloping roof. Later in the century, glass was used on both sides. Glasshouses were used for fruit crops such as melons, grapes, peaches and strawberries, and rarely for vegetable production. Protected agriculture was fully established with the introduction of polyethylene after the World War II. The first use of polyethylene as a greenhouse cover was in 1948, when Professor Emery Myers Emmert, at the University of Kentucky, USA, used the less expensive material in place of more expensive glass.

The total area of glasshouses in the world as per 1987 reports was estimated to be 30,000 ha and most of these were found in North-Western Europe. In contrast to glasshouses, plastic.... [download this ebook to read more]

[EBOOK] Essential Plant Pathology, Gail L. Schumann and Cleora J. D'Arcy, The American Phytopathological Society

Why Study Plant Pathology?

Plant pathology is the study of plant diseases. We could not survive on earth without plants, so their health is important to us. Photosynthesis is the source of the free oxygen necessary for aerobic respiration. Long ago, free oxygen became a component of the early atmosphere, leading to the creation of the ozone layer, which helps to protect us from ultraviolet radiation and makes life on land possible. Photosynthesis also is the source of fixed carbon, from which all organic molecules (including the components of our bodies!) are then produced. Directly or indirectly, plants provide all of the food on which the human population relies. In addition, plants provide feed for animals, shelter, fiber for clothing and paper, fuel, and ornamental flowers and landscape plants for our enjoyment.

Plant diseases reduce yields of food and cash crops, mar the beauty of ornamental plants, and reduce our ability to shelter and feed ourselves. In some cases, pathogens even produce toxic compounds that poison our food. It is impossible to separate plant diseases from the history and culture of humans. Plant diseases limit where crops can be grown and determine what foods are available to us. A single disease, late blight of potato, triggered the Irish potato famine of the 1840s and forever changed the history of Ireland and of North America, where many starving Irish peasants took refuge. Dutch elm disease has killed more than 5 million elm trees on the formerly tree-lined streets of cities in the United States and Europe. Citrus canker and soybean rust currently threaten multibillion dollar crops in the United States and around the world. Each year, local, state, and federal governments spend funds on quarantines and plant inspection services to control the movement of dangerous pathogens that threaten our food supply and the livelihoods of growers. The concern that bioterrorism may threaten genetically uniform crops, as well as farm animals and human populations, has made us more aware of the potential for damage by introduced pathogens. Billions of dollars are spent each year on the management of plant diseases, and yet it is estimated that plant diseases cause a 20% yield loss in food and cash crops. Of course, that does not mean that all yields are reduced by that amount. Some crops remain healthy, but others may be nearly destroyed, potentially causing starvation for large populations of people or loss of livelihood for farmers.

Aside from the practical aspects of keeping plants healthy, plant pathology is an amazing biological science that focuses on the interactions among host plants, pathogens, and the vectors that transmit the pathogens in various environments. Studies of the physiology and genetics of these interactions lead us to new discoveries in molecular biology and their applications in biotechnology. Knowledge of the ecological interactions of hosts and pathogens will help us understand our natural ecosystems, global climate change, and maintenance of biological diversity on our planet. All aspects of biology are encompassed in the study of plant pathology. This textbook and its accompanying online resources are designed to introduce students to the fascinating study of plant diseases.

[EBOOK] ENZYME INACTIVATION IN FOOD PROCESSING (Technologies, Materials, and Applications), Edited by Megh R. Goyal, PhD., Junaid Ahmad Malik, PhD., and Ravi Pandiselvam, PhD., CRC

Everything we do in the field of food science and technology revolves around food preservation. There are several advanced technologies for food characteristics, and redesigning is yet another possible method for preserving and processing food. Food enzymes, which are proteinaceous compounds, are extremely essential. The preservation of food is done by activating or deactivating the enzymes. This action can be done by thermal treatment, cooking, drying, cooling, and freezing. Several better inactivation technologies have shown potential applications have also been investigated by scientists and researchers

This book is a collection of novel emerging technologies dealing with inactivation of enzymes for the design of food and preservation through advanced technologies. This book serves as an excellent resource on the inactivation of food enzymes through basic concepts and chemical methods. It presents novel processing technologies for inactivation of food enzymes. It looks at the inactivation of food enzymes through ozone technology, pulsed electric fields, microwave processing and ohmic heating technology, dense-phase carbon dioxide and high-pressure processing, radiofrequency technology, ultraviolet and light emitted diode technologies, cold plasma technology, and ultrasonication of foods and food products. It discusses the extraction of phytonutrients and biocompounds from cereals and considers the inactivation of enzymes in the design of nutraceutical-based functional foods, in the design of specific foods for gut-microbiodata, in conjunction with omega-3 fatty acids, and for the fortification in food products. The volume also investigates the characteristics of dairy-based dry powders and millet starches. The book also explores the role of the bioactive compounds and metal ions, catalases secreted by medicinal plants and mushrooms for enzyme inactivation and biosensing. The role of bionanomaterials in nanoencapsulation and catalysis is also discussed.

This book, Enzyme Inactivation in Food Processing: Technologies, Materials, and Applications, will serve many professionals working in the area of food science, technology and engineering around the world. The book will also serve as a reference book for researchers, students, scholars, industries, universities, and research centers.
