“…In this connection, there are many visible symptoms of the adverse effects on the livelihood of the local population today. Restoration of the degraded landscapes will play a vital role in facilitating sustainable development (Lemeneh et al 2004) and is therefore highly desirable. Management of woodlands on a sustainable basis is a challenge for people living in many arid and semi-arid areas of the world.…”

Long-term climate-growth relationships, were examined in tree rings of four co-occurring tree species from semi-arid Acacia savanna woodlands in Ethiopia. The main purpose of the study was to prove the presence of annual tree rings, evaluate the relationship between radial growth and climate parameters, and evaluate the association of El Niño and drought years in Ethiopia. The results showed that all species studied form distinct growth boundaries, though differences in distinctiveness were revealed among the species. Tree rings of the evergreen Balanites aegyptiaca were separated by vessels surrounding a thin parenchyma band and the growth boundary of the deciduous acacias was characterized by thin parenchyma bands. The mean annual diameter increment ranged from 3.6 to 5.0 mm. Acacia senegal and Acacia seyal showed more enhanced growth than Acacia tortilis and B. aegyptiaca. High positive correlations were found between the tree-ring width chronologies and precipitation data, and all species showed similar response to external climate forcing, which supports the formation of one tree-ring per year. Strong declines in tree-ring width correlated remarkably well with past El Niño Southern Oscillation (ENSO) events and drought/famine periods in Ethiopia. Spectral analysis of the master tree-ring chronology indicated occurrences of periodic drought events, which fall within the spectral peak equivalent to 2-8 years. Our results proved the strong linkage between tree-ring chronologies and climate, which sheds light on the potential of dendrochronological studies developing in Ethiopia. The outcome of this study has important implications for paleoclimatic reconstructions and in restoration of degraded lands.

“…Non-timber forest products (NTFPS) are particularly important for women. In Cameroon, for example, close to 90% of NTFP traders in up to 25 markets were women, while in other cases women have been found to earn up to 30% of their incomes from NTFPs (Ruiz Perez et al 2002, Lemenih 2003. In Asia, the sale of NTFPs such as wild fruits and vegetables often provides the only source of cash available to landless women (Carr and Hartl 2008).…”

“…In Somalia and Ethiopia they are also used for the treatments of allergies, snake and insect bites, colds, coughs, diarrhea, headaches, syphilis, stomach complaints, back complaints, disinfections, purifications and hygiene, to correct female disorders during menopause and topically for the treatments of wounds in humans and livestock (Martinetz et al, 1989;Thulin and Claeson, 1991;Farah, 1994;Claeson and Samuelsson, 1998; Mulugeta Lemenih et al, 2003).…”

“…They have been used for several diseases (internal) and wound treatments by topical application both for human and domestic animals (Farah, 1994;Kuchar, 1995;Mulugeta Lemenih et al, 2003). Internally, they have been used to treat stomachache, snakebites, venereal complaints, chronic cough, polio, tumor, disorders in women, tumor, diarrhea, chest congestion, and back complaints Farah, 1994; Mulugeta Lemenih et al, 2003). Some frankincense types are chewed to refresh breath, and protect teeth and strengthen gums (Farah, 1994).…”

“…Furthermore, frankincense and myrrh have been and still be used as raw materials in many industries such as perfumery, food, beverage as well as for religious rituals and several other local uses (Hall and Oser, 1965; Council of Europe, 1981; Tucker, 1986;Hillson, 1988;Ford et al, 1992;Farah, 1994; FAO, 1995;Anonymous, 2001; Mulugeta Lemenih et al, 2003). Stiles (1988) emphasized that an even greater potential lies in developments to be made through research in the pharmaceutical, fragrance and flavour, food technology, epoxy resin/ plastics and coating industries to develop more products that would make use of these renewable resources.…”

Oleo-gum resins such as frankincense and myrrh are some of the economically and culturally valuable products obtained from trees and shrubs of the genera Boswellia and Commiphora, respectively. They are important natural plant products used in several industries that include pharmacology, food, flavour, liqueur and beverage, cosmetics, perfumery and others. Moreover, frankincense and myrrh have several local applications in medicinal, hygienic, and insecticide areas that could be developed through research. They are widely used in traditional medicines of several countries for treatments of a wide variety of ailments from embalming to cancer, leprosy, bronchitis, diarrhea, dysentery, typhoid, mouth ulcers, inflammatory complaints, viral hepatitis, female disorders, infections/wounds, coughs, tumour, and others. Although Ethiopia is one of the few countries that are endowed with large frankincense and myrrh resources, little proper exploitation of these resources has been made so far. In this paper a review is presented on pharmacological and industrial applications of these valuable resources. The information is expected to prompt the enormous economic opportunity that these resources could provide both at national and local levels. Concurrently, this opportunity, if properly exploited, will contribute significantly towards the conservation and management of the vegetation resources that yield frankincense and myrrh as well as their ecosystems.
