Book The State of Food and Agriculture 2021

Download or read book The State of Food and Agriculture 2021 written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2021-11-23 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: The COVID-19 pandemic exposed the vulnerability of agrifood systems to shocks and stresses and led to increased global food insecurity and malnutrition. Action is needed to make agrifood systems more resilient, efficient, sustainable and inclusive. The State of Food and Agriculture 2021 presents country-level indicators of the resilience of agrifood systems. The indicators measure the robustness of primary production and food availability, as well as physical and economic access to food. They can thus help assess the capacity of national agrifood systems to absorb shocks and stresses, a key aspect of resilience. The report analyses the vulnerabilities of food supply chains and how rural households cope with risks and shocks. It discusses options to minimize trade-offs that building resilience may have with efficiency and inclusivity. The aim is to offer guidance on policies to enhance food supply chain resilience, support livelihoods in the agrifood system and, in the face of disruption, ensure sustainable access to sufficient, safe and nutritious food to all.

Available in PDF, EPUB and Kindle. Book excerpt: In this edited collection, 17 internationally known authorities bring together the results of recent research on the natural history, ecology, behavior, morphology, and genetics of wasps as they pertain to the evolution of social behavior. The first part of the book opens with a review of the classification of the family Vespidae along with a revision of the subfamily Polistinae. Seven subsequent chapters deal with the natural history and social biology of each of the major taxa of social and presocial vespids. The second part of the book offers chapters on reproductive competition; worker polyethism; evolution of nest architecture, of queen number and queen control, and of exocrine glands; population genetics; the nutritional bsis of social evolution; and the nest as the locus of social life. The final chapter is a comparative discussion of social behavior in the Sphecidae, the only family of wasps besides the Vespidae in which well-developed social behavior is known. Providing a wealth of information about the biology of wasps, this comprehensive, up-to-date volume will be an essential reference for entomologists, evolutionary biologists, behavioral ecologists, ethologists, and zoologists.

Book Sustainable Horticultural Systems

Download or read book Sustainable Horticultural Systems written by Dilip Nandwani and published by Springer. This book was released on 2014-10-14 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sustainable horticulture is gaining increasing attention in the field of agriculture as demand for the food production rises to the world community. Sustainable horticultural systems are based on ecological principles to farm, optimizes pest and disease management approaches through environmentally friendly and renewable strategies in production agriculture. It is a discipline that addresses current issues such as food security, water pollution, soil health, pest control, and biodiversity depletion. Novel, environmentally-friendly solutions are proposed based on integrated knowledge from sciences as diverse as agronomy, soil science, entomology, ecology, chemistry and food sciences. Sustainable horticulture interprets methods and processes in the farming system to the global level. For that, horticulturists use the system approach that involves studying components and interactions of a whole system to address scientific, economic and social issues. In that respect, sustainable horticulture is not a classical, narrow science. Instead of solving problems using the classical painkiller approach that treats only negative impacts, sustainable horticulture treats problem sources.

Book Sperm Competition and the Evolution of Animal Mating systems

Download or read book Sperm Competition and the Evolution of Animal Mating systems written by Robert L. Smith and published by Elsevier. This book was released on 2012-12-02 with total page 710 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sperm Competition and the Evolution of Animal Mating Systems describes the role of sperm competition in selection on a range of attributes from gamete morphology to species mating systems. This book is organized into 19 chapters and begins with the conceptualization of sperm competition as a subset of sexual selection and its implications for the insects. The following chapter describes the relationship between multiple mating and female fitness, with an emphasis on determining the conditions under which selection on females is likely to counteract selection on males for avoiding sperm competition. Other chapters consider the female perspective on sperm competition; the evolutionary causation at the level of the individual male gamete; and the correlation of high paternal investment and sperm precedence in the insects. The remaining chapters are arranged phylogenetically and explore the sperm competition in diverse animal taxa, such as the Drosophila, Lepidoptera, spiders, amphibians, and reptiles. These chapters also cover the evolution of direct versus indirect sperm transfer among the arachnids or the problem for kinship theory presented by multiple mating and sperm competition in the Hymenoptera. This book further discusses the remarkable potential for sperm competition among certain temperate bat species whose females store sperm through winter hibernation and the mixed strategies and male-caused female genital trauma as possible sperm competition adaptations in poeciliid fishes. The concluding chapter examines the predictions concerning testes size and mating systems in the primates and the possible role of sperm competition in human selection. This book is of great value to reproductive biologists and researchers.

Book Grenada  Carriacou and Petite Martinique

Download or read book Grenada Carriacou and Petite Martinique written by Paul Crask and published by Bradt Travel Guides. This book was released on 2009 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: TRAVEL & HOLIDAY GUIDES. The volcanic island of Grenada and the smaller Grenadines, Carriacou and Petite Martinique, sit at the southern tip of the Windward Islands chain in the eastern Caribbean. In 2004, they were decimated by Hurricane Ivan. The nutmeg trees on which the economy was once reliant were destroyed, and buildings and infrastructure collapsed. But now the islands have been rebuilt, renovated and improved. They are once more open for business, and enjoying a newfound prosperity as visitor numbers increase year on year. This guide takes hikers on treks through the rainforest, and divers to The Bianca C, the largest shipwreck in the Caribbean. It shows cultural visitors the nation's diverse heritage and rich musical traditions and leads those in need of a little lie-down to unspoilt beaches and secluded coves.

Book Tourism in the Green Economy

Download or read book Tourism in the Green Economy written by World Tourism Organization and published by . This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Tourism Background Report is an extended version of the Tourism Chapter of the Green Economy Report (GER), which makes the case for investments in greener and sustainable tourism as a means to create jobs and reduce poverty while also improving environmental outcomes. The Report analyses the main variables that influence tourism development and aims to demonstrate that concerted "greener" policies can steer the growth of the sector toward a more sustainable path. Compared with a "business-as-usual" scenario, it shows how a green investment scenario would allow the sector to continue to expand steadily over the coming decades while ensuring significant environmental benefits such as reductions in water consumption, energy use and CO2 emissions. The Report aims at encouraging policy makers to support increased investment in greening the tourism sector.
