In this book we present recent studies that have been carried out on some widely used medicinal plants. The need for new and alternative treatments stem from the lack of efficiency of existing remedies for certain illnesses. We have compiled information that may be useful to researchers in their quest to develop new drugs.

Plants provide the food, shelter, medicines, and biomass that underlie sustainable life. One of the earliest and often overlooked uses of plants is the production of smoke, dating to the time of early hominid species. Plant-derived smoke has had an enormous socio-economic impact throughout human history, being burned for medicinal and recreational purposes, magico-religious ceremonies, pest control, food preservation, and flavoring, perfumes, and incense. This illustrated global compendium documents and describes approximately 2,000 global uses for over 1,400 plant species. The Uses and Abuses of Plant-Derived Smoke is accessibly written and provides a wealth of information on human uses for smoke. Divided into nine main categories of use, the compendium lists plant-derived smoke's medicinal, historical, ceremonial, ritual and recreational uses. Plant use in the production of incense and to preserve and flavor foods and beverages is also included. Each entry includes full binomial names and family, an identification of the person who named the plant, as well as numerous references to other scholarly texts. Of particular interest will be plants such as Tobacco (Nicotiana tabaccum), Boswellia spp (frankincense), and Datura stramonium (smoked as a treatment for asthma all over the world), all of which are described in great detail.

Two remarkable tales woven together - the story of the Kaokoveld, an arid eden in the remote north-west of Namibia, so nearly lost, but regained to become one of Africa's iconic wildlife tourism destinations, and also the story of a young man's search for an African way to do conservation in Africa. Garth Owen-Smith first visited the Kaokoveld in 1967. It was a life-changing experience. His unconventional ideas challenged both the conservation establishment and the former South African regime. Despite this, community-based conservation was pioneered in the Kaokoveld and today Namibia is a world leader in this field. But the early years - when the foundation for this ground-breaking approach to conservation was laid - are largely forgotten and untold. An Arid Eden: A Personal Account of Conservation in the Kaokoveld brings those years alive through the eyes of Owen-Smith, spanning four-and-a-half decades of extraordinary dedication, passion and achievement. The author and his partner Dr Margaret Jacobsohn have won some of the world's most prestigious conservation awards for their work in Namibia, which has always challenged convential wisdom. The NGO they founded continues to break conservation, agricultural and rural development paradigms.
