Throughout the world, traffic levels are increasing and, in urban areas, these increasing levels have led to pressures on the road networks which are causing serious economic, environmental and social problems. This book examines the full range of 'push and pull' Travel Demand Management measures. This covers areas of regulatory, pricing, planning and persuasive policies to encourage individuals to make their trips in off-peak periods, by a different mode or to find another way of carrying out the trip purpose. Applying such measures can result in a more efficient transport system, improved environmental conditions and improvements in safety as well as revenue generation for use on alternative transport systems. The editors conclude with a summary of findings within the book and suggestions for best future practice.

A focus on the minerals and gemstones of the East African region. A comprehensive introduction unpacks the topic and the regional geology; it is followed by an A to Z of minerals and gemstones, incorporating detailed text and multiple images for each specimen. The large format allows for a superb selection of photographs - pre-cut and polished specimens (and images to portray uses and jewelry where relevant) - to bring the subject alive.

The book presents 50 of the most recognizable and geologically interesting sites around South Africa, including some of palaeontological or historical renown and some of mining interest. The diverse selection includes sites such as Chapman’s Peak, Howick Falls, Walter Sisulu National Botanical Gardens, Mapungubwe, Tswaing Meteorite Crater and the Fraserburg Fossil Surface.

Each site is unpacked to reveal:

- key features

- geological heritage

- landscape and rock formations

- topics of local or historical interest

- things to see and do at the site and in the surrounding area.

Maps and GPS pointers make the sites easy to find, and some of the more complicated features are explained by means of simplified diagrams.

Nearly 1,000 colour images illustrate South Africa’s remarkable geology and bring the topic vividly to life, making the book suitable for armchair travel too.

Southern Africa is without equal in terms of geology, a treasure trove of valuable minerals with a geological history dating back some 3 600 million years. In addition, the evolution of plants and animals, especially mammals and dinosaurs, is well preserved in the region, which also has among the best records of the origin of modern man.

The story of earth and life provides an insight into this remarkable history – how southern Africa's mineral deposits were formed, how its life evolved and how its landscape was shaped. Along the way readers will be enthralled by accounts of the Big Bang that marked the beginning of time and matter, by drifting and colliding continents, folding and fracturing rocks, meteors colliding with the Earth, volcanic eruptions, and the start of life. Other topics include why South Africa is so rich in minerals, how glacial deposits came to be found in the Karoo, why dinosaurs became extinct, how mammals developed from reptiles, and how closely humans are related to the apes.

The answers to many such questions can be found in this title. Anyone interested in the landscape and ecosystems in which we live will be intrigued by this title.

A history of humanity on the brink of decline.

We are living through a period that is unique in human history. For the first time in more than ten thousand years, the rate of human population growth is slowing down. In the middle of this century population growth will stop, and the number of people on Earth will start to decline - fast.

In this provocative book, award-winning science writer Henry Gee offers a concise, brilliantly-told history of our species--and argues that we are on a rapid, one-way trip to extinction. The Decline and Fall of the Human Empire narrates the dramatic rise of humanity, how a scattered range of small groups across several continents eventually inbred, interacted, fought, established stable communities and food supplies, and began the process of dominating the planet. The human story is relatively brief―the oldest fossils of H. Sapiens date to approximately 300,000 years ago―yet the spread of our species has been unstoppable…until recently.

As Gee demonstrates, our population has peaked, and is declining; our environment is becoming inimical to human life in many locations; our core resources of water, arable land, and air are diminishing; and new diseases, simmering conflicts, and ambiguous technologies threaten our collective health. Can we still change our course? Or is our own extinction inevitable?

There could be a way out, but the launch window is narrow.

Unless Homo sapiens establishes successful colonies in space within the next two centuries, our species is likely to stay earthbound and will have vanished entirely within another ten thousand years, bringing the seven-million-year story of the human lineage to an end.

With assured narration, dramatic stories, and his signature sprightly humor, Henry Gee envisions new opportunities for the future of humanity―a future that will reward facing challenges with ingenuity, foresight, and cooperation.

Fully updated and expanded, this third edition of the top-selling Field Guide to Common Trees & Shrubs of East Africa now features more than 520 of the trees and shrubs – indigenous and naturalized exotics – commonly found in the region.

Each of the four sections – trees, shrubs, palms and mangroves – is arranged in alphabetical order according to scientifi c name. The book features:

• An informative introduction to families.

• Species accounts describing the plants’ habitat, bark, leaves, fl owers and fruit.

• General and commercial applications and uses in traditional medicine.

• Almost 2,000 photographs depicting the species, its fruit, fl owers and bark.

• Glossaries, both textual and illustrated, of botanical and medical terms.

It has not seemed desirable to include many words that are rarely if at all used at present and which are in the older glossaries many words from fields closely related to ecology such as forestry, range management, agronomy, soils, and genetics are included because of their wide usage in ecological literature.The definitions are usually those that are in accord with present general usage. It has not seemed wise to attempt to pronounce judgment on the desira-bility of, or the need for, certain terms since decisions are made by usage as a language grows. The inclusion of certain words in this dictionary does not necessarily imply that the author approves or recommends their use.
