Download or read book Sustainable Management of Phytoplasma Diseases in Crops Grown in the Tropical Belt written by Chrystel Y. Olivier and published by Springer Nature. This book was released on 2020-02-05 with total page 271 pages. Available in PDF, EPUB and Kindle. Book excerpt: With 160+ countries and islands, the tropical belt is the geographical region centered on the equator and limited by the tropics of Cancer and Capricorn. Tropical agricultural production is mostly for local consumption but cash crops are also present. Tropical agriculture is characterized by a significant lack of capital in research and agricultural systems and by a high prevalence of insect pests and diseases. Phytoplasma diseases are associated by bacteria-like pathogens living in plant sap and spread by sap-feeding insects. They are emerging diseases and are difficult to control, mostly because their epidemiology is not known. This book will focus on detection and prevention of phytoplasma diseases in field and horticultural crops grown in the tropical belt. The book will review current prevention methods used in small and large-scale farms, and present research results aiming at developing sustainable management of phytoplasma diseases in the tropics.

Download or read book Vetiver Grass written by National Research Council and published by National Academies Press. This book was released on 1993-02-01 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: For developing nations, soil erosion is among the most chronic environmental and economic burdens. Vast amounts of topsoil are washed or blown away from arable land only to accumulate in rivers, reservoirs, harbors, and estuaries, thereby creating a double disaster: a vital resource disappears from where it is desperately needed and is deposited where it is equally unwanted. Despite much rhetoric and effort, little has been done to overcome this problem. Vetiver, a little-known tropical grass, offers one practical and inexpensive way to control erosion on a huge scale in both humid and semi-arid regions. Hedges of this deeply rooted species catch and hold back sediments while the stiff foliage acts as a filter that also slows runoff and keeps moisture on site. This book assesses vetiver's promise and limitations and identifies places where this grass can be deployed without undue environmental risk.

Download or read book Handbook of Climate Change Management written by Walter Leal Filho and published by . This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate change is one of the major challenges of modern times. Its impacts are manifold and vary from sea level rise (especially relevant to those living in coastal areas), to the increased frequency of extreme events such as cyclones and storm surges, which not only poses problems to property and infrastructure, but also to human health. Climate change is also associated with damages to the physical and natural environment, as well as to biodiversity. According to the 5th Assessment Report produced by the Inter-Governmental Panel on Climate Change (IPCC), many geographical regions across the world are moderately or highly vulnerable to climate change, whose impacts may be further exacerbated by other human-induced pressures. The above state of affairs illustrates the need for a better and more holistic understanding of how climate change affects countries and regions on the one hand, but also on how the many problems it causes may be managed on the other, vis-a-vis a better ability to adapt. There is also a perceived need to showcase successful examples of how to duly address and manage the many social, economic and political problems posed by climate change around the world, in order to replicate and even upscale the successful ones. It is against this background that the Handbook of Climate Change Management has been produced. It contains papers prepared by scholars, social movements, practitioners and members of governmental agencies, undertaking research and/or executing climate change projects, and working with communities across all geographical regions. The Handbook focuses on "Research, Leadership, Transformation," meaning that it serves the purpose of showcasing the role these key areas play in respect of applied research, field projects and best practices to foster climate change adaptation worldwide.

This book was released on 1995-07-21 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A practical guide to selection, screening, and multiplecomparisons This book addresses experimenters who have knowledge of classicalexperimental design methodology and expands their repertoire beyondhypothesis testing by providing statistical methods appropriate forselection, screening, and multiple comparisons. It concentrates onthree types of procedures: selection procedures that use the"indifference-zone" approach, screening procedures using the"subset" approach, and multiple comparison procedures involvingnormal means. This is the first book, specifically designed forpractitioners, to bring into focus many developments in the fieldpreviously covered only in university courses. It also presents newresults on the comparison of procedures that have been obtainedspecifically for this volume. This self-contained volume describes methods for designingexperiments when the scientific objective is selection of besttreatments, screening a set of treatments, and multiple comparisonsamong treatment means. The book emphasizes procedures appropriatein a variety of practical settings including those that requireblocking and randomization restriction. It compares the relativemerits of procedures when several different methods can be used inthe same circumstances. Providing practical guidance for experimenters in agriculture,engineering, medicine, and other empirical sciences, this book mayalso be used for a one-semester graduate course in selectionmethodology or to augment traditional courses in experimentaldesign. Design and Analysis of Experiments for Statistical Selection,Screening, and Multiple Comparisons: * Shows how selection and screening can be applied to data thatfollow one of three important probability models--normaldistribution, binomial distribution, and the multinomialdistribution models * Provides an extensive comparison of procedures, allowingexperimenters to choose among competitors when several differentprocedures are feasible for a given application * Gives an extensive set of tables of constants necessary toimplement the procedures * Supplements the tables of constants with listings of FORTRANprograms so that experimenters are not limited to those valuescovered by the tables * Focuses on frequent formulations, while also providing referencesto Bayesian and other alternative developments in the Chapter Notes
Download or read book Plants for Your Food Forest written by Plants for a Future and published by Independently Published. This book was released on 2021-06-15 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: A food forest is a form of regenerative farming, a designed ecosystem modelled on nature, with the aim of growing food and sequestering carbon at the same time. As a forest it will consist of plants which occupy different layers, typically a canopy layer, shrub layer, herb layer and climbers. All plants will be perennials in order for the soil to be wild, undisturbed and regenerating. All plants will be food producing, will sequester carbon in their woody parts or in the soil, and will have useful functions in the forest ecosystem. The choice of what to grow in a food forest is challenging. It is not simply a matter of deciding what would be good to eat, and planting the corresponding food plants in beds alongside rows or patches of woodland. Most books about food forests, woodland gardening or carbon farming concentrate on the design principles involved. The focus of this book is the plants, their characteristics and personalities, what they have to offer a food forest ecosystem, as well as what kinds of foods they yield. We have selected over 500 plants that provide a mix of different growing conditions, plant size and structure, type of food, and contribution to a food forest ecosystem. There is also a quick-reference table of the key characteristics. The featured plants are arranged in sections corresponding to Forest Layer: Shrubs, Groundcover Shrubs, Trees, Herbaceous Plants, Herbaceous Groundcover Plants, Running Bamboos, Bulbs, Climbers. Further details of all the plants described here are available from the PFAF Plants Database, which can be accessed free of charge at pfaf.org

This book was released on 1993-02-28 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is based on more than 1000 references to English and French articles produced in the region over many decades. A comprehensive review of the achievements in farming and research in both wet and dryland is given, related to the grasslands of: Eastern Africa, extending from Malawi to Eritrea, including Ethiopia, Kenya, Uganda, Tanzania, Somalia, Zambia, Rwanda, Burundi, Sudan and eastern Zaire. Sown grasses, within the time-proven system of mixed-farming based on crop-grass rotations. Fodders, e.g. Elephant grass, dryland-Sorghum, lucerne, Leucaena, tropical legumes and hay.£/LIST£ The main objectives of the book are to illustrate the value of East African grasses and fodders for: Livestock: East Africa is the gene-centre of the world's most famous cultivated tropical grasses capable of achieving high animal performance, also without fertilizer. Soil fertility maintenance: local farmers pioneered the practice of grass fallows with Elephant grass to restore soil fertility. This was later extended to sown grasses to accelerate the restoration process. Crop yields are doubled following pasture. Environmental protection: priority in natural grassland is to prevent deterioration. In crop-pasture rotations grasses are effective in trapping rainfall and in reducing erosion by improved soil structure. Topics discussed include animal manure versus fertilizer; zero versus direct grazing; fodder crops (annual and perennial) versus grass conservation; seed production and plant breeding. The main species in cultivation are described in detail.
