Download or read book Essential Plant Nutrients written by M. Naeem and published by Springer. This book was released on 2017-08-07 with total page 571 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explores the agricultural, commercial, and ecological future of plants in relation to mineral nutrition. It covers various topics regarding the role and importance of mineral nutrition in plants including essentiality, availability, applications, as well as their management and control strategies. Plants and plant products are increasingly important sources for the production of energy, biofuels, and biopolymers in order to replace the use of fossil fuels. The maximum genetic potential of plants can be realized successfully with a balanced mineral nutrients supply. This book explores efficient nutrient management strategies that tackle the over and under use of nutrients, check different kinds of losses from the system, and improve use efficiency of the plants. Applied and basic aspects of ecophysiology, biochemistry, and biotechnology have been adequately incorporated including pharmaceuticals and nutraceuticals, agronomical, breeding and plant protection parameters, propagation and nutrients managements. This book will serve not only as an excellent reference material but also as a practical guide for readers, cultivators, students, botanists, entrepreneurs, and farmers.

Download or read book Lagoons of Sri Lanka written by Silva, E. I. L. and published by IWMI. This book was released on 2013-03-01 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sri Lanka, an island in the Indian Ocean, has lagoons along 1,338 km of its coastline. They experience low-energy oceanic waves and semidiurnal microtidal currents. The Sri Lankan coastal lagoons are not numerous but they are diverse in size, shape, configuration, ecohydrology, and ecosystem values and services. The heterogeneous nature, in general, and specific complexities, to a certain extent, exhibited by coastal lagoons in Sri Lanka are fundamentally determined by coastal and adjoining hinterland geomorphology, tidal fluxes and fluvial inputs, monsoonal-driven climate and weather, morphoedaphic attributes, and cohesive interactions with human interventions.Most coastal lagoons in Sri Lanka are an outcome of mid-Holocene marine transgression and subsequent barrier formation and spit development enclosing the water body between the land and the sea. This process has varied from one coastal stretch to another due to wave-derived littoral drift, sediment transport by tidal fluxes, fluvial inputs and wave action or, in other words, sea-level history, shore-face dynamics and tidal range as the three major factors that control the origin and maintenance of the sandy barrier, the most important features for the formation and evolution of coastal lagoons with their landward water mass. In certain stretches of Sri Lanka’s coastline, formation of the barrier spit was very active due to shore-face dynamics that resulted in chains of shore parallel, elongated lagoons. They are among the most productive in terms of ecosystem yield and show some similarities to large tropical lagoons with respect to sea entrance, zonation, biodiversity and ecosystem services. However, some of them become seasonally hypersaline due to lack of freshwater input and high evaporation. Functions and processes of some of these water bodies are fairly known. There are a fair number of small back-barrier lagoons of different shapes and sizes whose origin goes back to sea-level history. They are located on low-energy coasts with prominent beach ridges and restricted hinterland geomorphology. Mixing processes of these landward indentations are hindered by elevated sand dunes, and their salinity increases due to poor freshwater input and high evaporation leading to seasonally hypersaline conditions. These sedimented lagoons, primarily confined to the southeastern coast of the island, are biologically the least productive, with limited ecosystem values and services. Another group of moderately elongated semicircular, slightly large lagoons in the same coast, formed exclusively by submergence due to mid-Holocene sea-level rises, do not receive sufficient freshwater input leading to seasonally hypersaline conditions. They are also biologically unproductive but some are ecologically important since they provide habitats conducive to migratory birds. In contrast, some lagoons on the southern coast receive sufficient freshwater via streams draining the wet zone, maintain more estuarine salinities, exhibit rich biodiversity and serve as functional resource units. Lagoons formed by mid-Holocene submergence and recession of water level with simultaneous chain barrier formation on the high energy southwest coast, which includes cliffs, small bays and headlands, show peculiar configurations and link channel characteristics. Some of these irregular water bodies have clusters of small isles and luxuriant mangrove swamps with high biodiversity but not very rich in catadromous finfish and shellfish species due to the restricted nature of the entrance channel and nondistinct salinity gradients. The barrier-built, seasonally hypersaline lagoon complex in the Jaffna Peninsula, the largest lagoon system in the country with multiple perennial entrances show extremely narrow salinity ranges towards the upper limit of salinity. The main lagoon is elongated and the shore parallel to eastward and southward extensions is connected by narrow channels. The other lagoon in the Jaffna Peninsula is elongated, shore parallel and ribbon-shaped and receives tidal water throughout the year but freshwater is received only from precipitation and surface runoff. Even though the lagoons in the peninsula are extremely rich in ecosystem heterogeneity their hydrology and hydrodynamics have been severely disturbed by infrastructural development for transportation and by attempts to create a freshwater river for Jaffna. There are a few virgin lagoons of moderate size also on the northern coast, south of the Jaffna Peninsula on both the east and west sides. They look very typical tropical lagoons rich in biodiversity and biological production but their structure, functions and values are virtually unknown in scientific or socioeconomic terms. The lagoons located on the east coast are not numerous but relatively large in extent. They are also an outcome not only of mid-Holocene sea-level rises but of submerged multi-delta valleys or abandoned paleo estuaries. When inundated, the multi-delta valley configuration became elongated and is shore parallel with a smooth seaward shoreline; both shorelines become irregular when coastal waves are weak, and internal waves are created by the action of local winds. Configuration of a lagoon formed by inundation of an abandoned river valley is irregular with a long entrance channel extended landward. These lagoons are highly productive with a variety of associated ecosystems, large open water areas and wide perennial sea entrances. When the lagoon is too much elongated, zonation is prominent due to fewer entrance effects. Lagoons form a particular type of natural capital which generates use values (fish, shrimp, fuelwood, salt, fodder, ecotourism, anchorage, recreation, etc.) and nonuse values (habitat preservation, biodiversity, ecosystem linkages, etc.) contributing positively towards improving the human well-being. Of many values of lagoons in Sri Lanka, only the extractive values are generally utilized at present, by way of fish and shrimp catches, salt production and use of mangrove for various purposes. Besides, coastal lagoons generate a range of nonextractive use values and nonuse values, which could add towards the total economic value. Misuse has taken place at several instances when “use” adversely affects the status of the resources or the health of the ecosystem due to vulnerability and poverty, population pressure, urbanization, development activities and multi-stakeholder issues. The status of lagoon resources shows that the resources in the majority of Sri Lankan lagoons still remain satisfactory, somewhat good or very good. Nevertheless, concerns for management of lagoons in Sri Lanka exist only where “use values” (extractive values, such as fish and shrimp) exist. There is no evidence of resources management in lagoons for inspirational, scholarly values or tacit knowledge of the same. Management for use values exhibits several stages from zero management to comanagement via community management and state intervention. Most of Sri Lanka’s lagoons have the potential for generating high extractive and nonextractive use values which could improve the human well-being, while maintaining resources sustainability. Unfortunately, these potentials have not been understood or “seen” yet by the relevant authorities, although a few instances of exploring this potential were noticed.

Download or read book Nutraceuticals written by Hammad Ullah and published by Walter de Gruyter GmbH & Co KG. This book was released on 2024-04-22 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: The term nutraceuticals is applied to the products isolated from the herbal sources, nutrients or dietary supplements, processed foods, (cereals, soup and beverages) and specific diets, that may also used as medicine other than nutrition. It usually refers to the foods derived products which may sell in medicinal form, possessing physiological benefits to the host while promoting health and wellness and provide protection against chronic disorders. They may also increase the life expectancy, delay the aging and/or support the structure and function of the body organs. Demand for nutraceuticals with potential to prevent and treat chronic disorders has been interestingly increasing over the past few years. Based on food sources, nutraceuticals are classified into dietary fibers, probiotics, prebiotics, polyunsaturated fatty acids (PUFAs), vitamins, polyphenols and spices. A dietary supplement is generally considered as product containing vitamins, minerals, amino acids, and medicinal plants that are indented to be used to supplement the diet or a concentrate, metabolite, constituent, extract, or combinations of these ingredients. Broadly, nutraceuticals are any of these ingredients or supplements using for health purposes other than nutrition. This book on the fundamentals of Nutraceuticals is organized in two parts i.e., the introductory aspects of macro- and micro-nutrients, gut microbiota regulation, nutraceuticals and drug interactions, while the second part is focusing on the biological benefits of nutraceuticals in different disease states. Besides, this book is also addressing the safety aspects of nutraceuticals and phytotherapeutic support in pregnancy. Including contributions from the experts in the field, target audience (pharmacists, nutritionists, other healthcare providers, and researchers in food and nutrition sector) will be benefited with the updated literature on nutraceuticals and dietary supplements.

Download or read book Southeast Asian Water Environment 1 written by S. Ohgaki and published by IWA Publishing. This book was released on 2005-12-01 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: Southeast Asia has undergone rapid commercial and industrial development over the past half century, which continues to bring economic stability and prosperity to its inhabitants. The combined impacts of population growth, urbanization, and industrialization continue to put pressure on the natural resources and the environment. At the same time, globalization is another momentous challenge for the region. Southeast Asian megacities are some of the most dynamic and diverse regions, which are playing a key role in achieving global sustainability. Twelve out of nineteen megacities of the world are located in the region, where highly developed areas coexist with poorly developing areas where large economic growth is expected. The poor quality of the living standards of the latter creates many environmental problems that are major threats to the inhabitants of the region. The Southeast Asian environment has been degraded by the release of industrial and domestic wastes, agricultural and aquacultural chemicals, and pollutants from automobiles. It suffers from water-related disasters, Tsunami, floods, typhoons, etc. In order to deal with these issues an integrated approach from the inhibitants, governments and researchers is essential. The environmental threats arising from the increasing population, overuse of natural resources, industrialization, urbanization, and natural disasters present ever increasing challenges to pursuing sustainable development of the region. Many developed countries such as Japan have experiences of dealing with severe environmental pollution and this publication is the result of building an academic network among researchers of related fields from different regions to exchange information. This book will be an invaluable source of information for all those concerned with achieving global sustainability within the water environment in developing regions, including researchers, policy makers, NGOs and NPOs.

Available in PDF, EPUB and Kindle. Book excerpt: This edited book is a comprehensive collection of chapters on various clean energy technology such as solar energy, waste biomass as energy, hydro-electricity generation, biodiesel production from biomass and strategies to cater the demand of clean renewable energy. Clean energy technologies also enhance economic growth by increasing the supply of energy demand and tackling environmental challenges and their impacts due to the use of other conventional sources of energy. The conventional/non-conventional energy production methods are efficient but it has adverse effects on environment and human health. As environmental concerns are not avoidable therefore the necessity of clean energy production comes in to the picture. The clean energy can be produced by different wastes which are caused for the environmental pollution. This book covers various aspects of new and renewable clean energy production technology and its utilization in different fields. This is a useful reading material for students and researchers involved in clean energy study.

Download or read book Rethinking Development in South Asia written by Farid Uddin Ahamed and published by Cambridge Scholars Publishing. This book was released on 2022-03-17 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book challenges the way development has been conceptualized and practiced in South Asian context, and argues for its deconstruction in a way that would allow freedom, choice and greater well-being for the local people. Far from taking development for granted as growth and advancement, this book unveils how development could also be a destructive force to local socio-cultural and environmental contexts. With a critical examination of such conventional development practices as hegemonic, patriarchal, devastating and failure, it highlights how the rethinking of development could be seen as a matter of practice by incorporating people’s interest, priorities and participation. The book theoretically challenges the conventional notion of hegemonic development and proposes alternative means, and, practically, provides nuances of ethnographic knowledge which will be of great interest to policy planners, development practitioners, educationists and anyone interested in knowing more about how people think about their own development.

Download or read book Nutritional Marine Life written by Ramasamy Santhanam and published by CRC Press. This book was released on 2014-12-15 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: The nutritional benefits of marine flora and fauna are well known. Fish and crustaceans provide high-quality sources of amino acids—nutritionally important proteins found in only small amounts in cereals and grains. Nutrients and minerals in seafood can improve brain development and reproduction and there are strong links between fish and heart health. Similarly, other organisms such as phytoplankton and invertebrates possess several nutrients of health importance. All of these benefits are critical to global nutrition and particularly important to food-deficient, low-income countries. The first book of its kind, Nutritional Marine Life explores the nutritional characteristics of the different species of the following groups of edible marine life: Phytoplankton Seaweeds and marsh plants Jellyfish Crustaceans Mollusks Echinoderms Prochordate Fish Turtles Mammals For each species, the book discusses its classification, common name, habitat, global distribution, biological features, and nutritional facts. The highly accessible style and high-quality photographs make it easy to identify nutritionally and commercially important marine species. The book is ideal for students and researchers in fisheries and aquaculture and in related marine biology and biotechnology disciplines. It is also suitable as a reference for practitioners in those fields as well as dieticians, food scientists, and physicians interested in knowing about the health benefits of seafood.
