Our food and the way we eat are products of our past. A celebration of produce, people and place, Eat Your History dishes up stories and recipes from Australian kitchens and dining tables from 1788 to the 1950s. Jacqui Newling, Sydney Living Museums' resident gastronomer, invites you to share forgotten tastes and lost techniques and rediscover some of the culinary treasures that sustained many generations of Australians.
Biological control of weeds has been practised for over 100 years and Australia has been a leader in this weed management technique. The classical example of control of prickly pears in Australia by the cactus moth Cactoblastis cactorum, which was imported from the Americas, helped to set the future for biocontrol of weeds in many countries. Since then there have been many projects using Classical Biological Control to manage numerous weed species, many of which have been successful. Importantly, there have been no serious negative non-target impacts – the technique, when practised as it is in Australia, is safe and environmentally friendly. Economic assessments have shown that biocontrol of weeds in Australia has provided exceedingly high benefit-to-cost ratios. This book reviews biological control of weeds in Australia to 2011, covering over 90 weed species and a multitude of biological control agents and potential agents. Each chapter has been written by practising biological control of weeds researchers and provides details of the weed, the history of its biological control, exploration for agents, potential agents studied and agents released and the outcomes of those releases. Many weeds were successfully controlled, some were not, many projects are still underway, some have just begun, however all are reported in detail in this book. Biological Control of Weeds in Australia will provide invaluable information for biological control researchers in Australia and elsewhere. Agents used in Australia could be of immense value to other countries that suffer from the same weeds as Australia. The studies reported here provide direction to future research and provide examples and knowledge for researchers and students.
Cactus plants are precious natural resources that provide nutritious food for people and livestock, especially in dryland areas. Originally published in 1995, this extensively revised edition provides fresh insights into the cactus plant’s genetic resources, physiological traits, soil preferences and vulnerability to pests. It provides invaluable guidance on managing the resource to support food security and offers tips on how to exploit the plant’s culinary qualities.
This is the remarkable story about a plague of prickly-pear cactus plague that nearly crippled Australia during the first quarter of the 20th century. At its peak, the cactus invasion held within its spiny grip more than 60 million acres of choice farm and dairy land and was still spreading at a rate of over a million acres a year. Like some monster from outer space, roads, farms, and entire towns disappeared beneath its "octopus-like" growth. The author takes the reader back into time to hear first-hand accounts of what life was like in this "green Hell" and to explore the reasons why such a plague occurred. Readers will also learn how a group of mostly self-taught biologists were able to save that country by introducing a small brown moth, with the big name of Cactoblastis cactorum, from Argentina whose larvae are voracious cactus-eaters. Finally, there is a special section about gripping new developments concerning this small insect hero that now puts the ecology of the American deserts at serious risk and how a team of American scientists dedicated to reducing that risk are facing that challenge. Complete with 30 color photos, extensive notes and bibliography section, and index.
