Restructuring Global and Regional Agricultures - Transformations in Australasian Agri-Food Economies and Spaces (Paperback):... Restructuring Global and Regional Agricultures - Transformations in Australasian Agri-Food Economies and Spaces (Paperback)
David Burch, Jasper Goss, Geoffrey Lawrence
R1,143 Discovery Miles 11 430 Ships in 10 - 15 working days

First published in 1999, this collection of papers represents the latest thinking on the effects of globalisation and agri-food restructuring from a regional and peripheral perspective. The book breaks new ground in our understanding of the relationship between the global, regional and local levels in the sphere of agri-food production. While Australia and New Zealand are important components of the agri-food system, the economic and political decisions which impact at the regional and local level are usually made elsewhere - often in the boardrooms of global companies and the political institutions of Europe and North America. At the same time, however, Australia and New Zealand have sought to establish some independent room for manoeuvre. In Australia this can be seen in the targeting of consumers in South East Asia, and New Zealand has experienced both sweeping deregulation and niche marketing of goods such as organic produce. The success or failure of these strategies cannot currently be determined, but this invaluable collection presents and discusses some possible future scenarios. Featuring 31 specialists in sociology, geography, social anthropology, veterinary science, environmental studies and sustainable development, it is a product of the Agri-Food Research Network. The volume includes 19 essays which attempt to conceptualise a series of global trends and their local ramifications, explore Australian and New Zealand experiences of agri-food restructuring in historic, ideological and discursive terms, and analyse local policy and politics and the influence on rural producers, along with studying four key concepts underpinning agri-food research and the possibilities for their application in new areas. .

This Book compliles Current Charts and Tide Prints for Puget Sound. Current Charts show the values of the currents at each reference station. There is one chart for every hour throughout the cycle. They are indexed to the tidal current at Admiralty Inlet. Tide Prints show the flow patterns and how they evolve throughout the current cycle. There is one print for every 3 hours throughout the cycle. They are indexed to the tide height in Seattle. Comparing Tide Prints and Current Charts shows the locations of eddies and bands of current, and how these bands and eddies move and interact as the current cycle evolves. These are both perpetual publications, good for any year.

Find Your Way at Sea, No Matter What.

Inherently interesting and fun to read . . . provides the clearest understanding of general navigation principles we've seen yet.--BoatU.S. .

Thorough and authoritative.--"Sea Kayaker,"

A definitive work of instant appeal to seamen of all levels of experience.--The Navigation Foundation.

Every sailor knows that instruments can fail. Things get wet, break, fall overboard. Whether youre safe on your boat or drifting in a life raft, let David Burch show you how to find your way no matter what navigational equipment you have. Often relying on common materials like a small stick, a plastic bottle, even a pair of sunglasses, Burch explains how to make use of all available means--from the ancient skills of Polynesian navigators to the contrails of airliners overhead--to calculate speed, direction, latitude, and longitude and to perform all aspects of piloting and dead reckoning. . Learn how to. . Steer by sun, stars, wind, and swells . Estimate current and leeway. Improvise your own knotmeter or plumb-bob sextant . Find the sun in a fogbank . Estimate latitude with a plate and a knotted string . And more vital information. .

David Burch is the founder and president of the Starpath School of Navigation (www.starpath.com) and the author of nine books on navigation, including "Radar for Mariners" and "Fundamentals of Kayak Navigation," His articles appear in "Cruising World," "Ocean Navigator," "Sailing," "Sea Kayaker," and elsewhere. A past Fulbright Scholar with a Ph.D. in physics, Burch has more than 70,000 miles of ocean sailing experience, ranging from the Arctic to Tahiti. He has sailed across the Pacific twelve times, three timesnavigating winning yachts in the Victoria - Maui Yacht Race. He has received the Institute of Navigations Superior Achievement Award for outstanding performance as a practicing navigator..

This book is an updated and expanded edition of a text that has been used in navigation courses for 30 years. It covers practical small-craft navigation (sail, power, or paddle), starting from the basics and ending with all that is needed to navigate safely and efficiently on inland and coastal waters in all weather conditions. It is for beginners, starting from scratch, or for more seasoned mariners who wish to expand their skills. Topics include: Charts, Chart Reading, and Chart Plotting Instruments and Logbook Procedures Compass Use Piloting and Dead Reckoning Lights and Buoyage Tides and Currents Rules of the Road GPS and other Electronic Aids The GPS tells us where we are and how fast we are moving in what direction, but it can never tell us the safest, most efficient route to our destination. That fundamental task requires the basic navigation skills taught in this book, which we can use as well to check the GPS underway, and then be prepared to navigate without the GPS if we need to. The hallmark of good seamanship is to look ahead and be prepared. The text covers not only the long tested traditional methods of navigation but also the efficient use of the latest technology in electronic navigation and charting.

The Barometer Handbook (Paperback): David Burch The Barometer Handbook (Paperback)
David Burch; Designed by Tobias Burch
R685 R614 Discovery Miles 6 140 Save R71 (10%) Ships in 18 - 22 working days

The barometer remains the most important tool for evaluating and predicting the weather. This book explains why knowing accurate values of the atmospheric pressure can improve this process and benefit all applications. Ways to evaluate and calibrate aneroid and electronic barometers using readily available data by Internet or telephone are clearly described. Tactical applications to marine navigation are covered. The book also includes worldwide average monthly pressures and their standard deviations. With the exception of trained meteorological crews, barometers in the past were used at sea primarily to learn if the pressure was going up or down, and whether it was doing this rapidly or slowly. And from this we made an educated guess of a likely consequence, usually in conjunction with other observations. Outside of professional marine use, little effort was made to know the true pressure for several reasons. We did not know what to do with it if we had it, and more often we could not get it if we wanted it, because most barometers were not calibrated. This has changed. We now have many valuable applications of accurate pressure, and we also have affordable ways to get it, and we have convenient ways to prove our instruments work properly. The main goal of this book is to show how all this comes about, and to give more insight into this fascinating, venerable instrument that has been with us for 150 years. Another goal is to introduce users to the new breed of electronic devices that are in the process of revolutionizing how we do weather at sea. We also re-introduce mariners to several classic aneroid instruments that are highly accurate and tested at sea for over 70 years, and why we benifit from having both a calibrated aneroid and an electronic barometer on board.
