Download or read book Geospatial Technologies for Crops and Soils written by Tarik Mitran and published by Springer Nature. This book was released on 2020-10-24 with total page 528 pages. Available in PDF, EPUB and Kindle. Book excerpt: The sustainable development of the agriculture sector is the only option to meet the demands of increased and economically viable production in a changing climate. This means there is a need to introduce the latest technologies to enhance production, and also help policymakers make decisions for the future. Geospatial technologies & tools, such as remote sensing, geographical information systems (GIS), global positioning systems (GPS), and mobile & web applications, provide unique capabilities to analyze multi-scale, multi-temporal datasets, and support decision-making in sustainable agriculture development and natural resources management. Further, the availability of reliable and timely geospatial information on natural resources and environmental conditions is essential for sustainable agricultural development and food security. Since remote sensing solutions are fast, non-destructive and have large spatial coverage, they can play a significant role in the identification, inventory, and mapping of land resources. Over the past four decades, remote sensing has proved to be a cost-effective and powerful tool to assess crop and soil properties in varying spatial and temporal scales using both visual and digital techniques. Satellite remote sensing coupled with GIS & mobile-app based positional information has emerged as an efficient tool for optimizing input resources, and minimizing cost of production and risk of biotic/ abiotic factors nature to promote sustainable agriculture. This book comprehensively documents the applications of space-based technologies for crop and soil assessments for the sustainable development of agriculture.
Download or read book The State of the World s Aquatic Genetic Resources for Food and Agriculture written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2019-07-24 with total page 291 pages. Available in PDF, EPUB and Kindle. Book excerpt: The conservation, sustainable use and development of aquatic genetic resources (AqGR) is critical to the future supply of fish. The State of the World’s Aquatic Genetic Resources for Food and Agriculture is the first ever global assessment of these resources, with the scope of this first Report being limited to cultured AqGR and their wild relatives, within national jurisdiction. The Report draws on 92 reports from FAO member countries and five specially commissioned thematic background studies. The reporting countries are responsible for 96 percent of global aquaculture production. The Report sets the context with a review of the state of world’s aquaculture and fisheries and includes overviews of the uses and exchanges of AqGR, the drivers and trends impacting AqGR and the extent of ex situ and in situ conservation efforts. The Report also investigates the roles of stakeholders in AqGR and the levels of activity in research, education, training and extension, and reviews national policies and the levels of regional and international cooperation on AqGR. Finally, needs and challenges are assessed in the context of the findings from the data collected from the countries. The Report represents a snapshot of the present status of AqGR and forms a valuable technical reference document, particularly where it presents standardized key terminology and concepts.

Download or read book Freshwater Mollusks of the World written by Charles Lydeard and published by JHU Press. This book was released on 2019-04-02 with total page 255 pages. Available in PDF, EPUB and Kindle. Book excerpt: The definitive resource on the biology and evolution of freshwater mollusks. There are more species of freshwater mollusks—well over 5,000—than all the mammal species of the world. Freshwater mollusks are also arguably the most endangered fauna on the planet. Yet few references exist for researchers, shell enthusiasts, and general readers who are interested in learning more about these fascinating creatures. In Freshwater Mollusks of the World, Charles Lydeard and Kevin S. Cummings fill that void with contributions from dozens of renowned mollusk experts. Touching on 34 families of freshwater gastropods (snails) and 9 families of freshwater bivalves (mussels and clams), each chapter provides a synthesis of the latest research on the diversity and evolutionary relationships of the family. The book also includes • a look at how evolving DNA sequencing data techniques help shed light on mollusk taxonomy • distribution maps of each family's biogeographic locales • a representative photo and distribution map for each of the freshwater mollusk families • the latest information on each family's conservation status—and how to reverse the habitat destruction, modification, and pollution that threatens it • a discussion of the ecological and economic damages caused by invasive mollusk species, as well as their role as disease vectors Mollusks provide us with amazing biogeographical insights: their ancient fossil record goes back over 500 million years, and their distribution patterns are a reflection of past continental and climate changes. The only comprehensive summary of systematic and biodiversity information on freshwater mollusk families throughout the world, this reference is a must for malacologists, limnologists, ichthyologists, stream ecologists, biogeographers, and conservation biologists.

Book excerpt: The first comprehensive guide to the aquatic plants of the region Beneath the surface of bodies of freshwater—springs, streams, rivers, ponds and lakes—there is a world of plants of great variety and beauty, a realm that is often poorly known and understood. Correctly identified, these plants can tell us much about the character and condition of the habitats in which they live. A collaboration of Danish, German, and British field botanists specializing in freshwater plants, this guide presents all of the known aquatic plants of Northern and Central Europe, including Britain and Ireland, as well as many marginal and wetland species. This is the first comprehensive guide to the identification of the region’s 410 species and hybrids of both native and non-native ferns and flowering plants that are dependent upon freshwater wetlands. Following the latest taxonomy, the book features 358 plates in pen and ink, more than 1,400 colour photographs, illustrated keys, distribution maps and detailed descriptions. The introduction gives an overview of evolution, anatomy and morphology, ecology, eco-physiology, research traditions and more, and the book also includes guidelines for working with aquatic plants.

Book excerpt: This book presents light microscopic anatomical images of aquatic and wetland plant stem. It features double-stained cross- and longitudinal sections of almost 400 species of vascular plants from the lowland to the alpine zone in Central Europe, including plants from lakes, ponds, rivers, bogs, fens, wet meadows, saline meadows, tall herb associations and alpine snow beds. The microscopic photographs at various magnifications are supplemented with detailed anatomical descriptions.
