It has been found that through application of in situ conservation of natural trees with respect to rapid human population growth, the available natural strands of valuable plants such as African sandalwood have not been able to meet the demands of the people in world specifically developing countries. However, advances in plant biotechnology provide new options for collection, multiplication and short- to long-term conservation of Osyris lanceolata species, using in vitro culture techniques. Different aspects of biotechnological applications can be extensively used to reduce the risk of extinction of this valuable plant species and to improve the quality and quantity of essential oils produced by it. Therefore, tissue culture appears to be a promising approach for the propagation and conservation of African sandalwood plant.展开更多

Since his inaugural trip abroad, Xi has repeatedly speeches when addressing international catchphrase received as much appeal as used the term ＂Chinese Dream＂ in his audiences. However, nowhere has the in Africa. Simultaneously, African academics and other interested parties have observed the promotion of the idea of an African Dream by the Chinese Communist Party （CCP） with great suspicion as they view it simply as a projection of China＇s own foreign policy onto Africa. But what do the Chinese Dream and African Dream actually mean？ How can we make sense out of these terms？ In order to decode or demystify the meaning behind the Chinese Dream narrative in the context of China＇s foreign policy, this paper argues that it is essential to examine how it is constructed and projected to the international audience, in particular to Africa. The Chinese Dream is understood as a narrative which is strategically used by the CCP in order to shape perceptions and behavior of other international actors according to their own agenda. Moreover, the dynamic interactions between the media and politics and how they impinge on the formation and projection of the Chinese Dream and African Dream narrative will also be taken into account.展开更多
