Mechanisms of bush encroachment and its inter-connection with rangeland degradation in semi-arid African ecosystems:a review 被引量:1

Many studies show that semi-arid rangelands throughout the world have been rapidly converted from a grassland state to a bush encroachment state during the past 50 years. Bush encroachment includes the spread of local woody species and/or incursion of woody species introduced from other ecosystems into semi-arid savannas and grassland ecosystems. Rangeland degradation due to bush encroachment causes several challenges, affecting the production of livestock and pastoral people livelihoods in most parts of Africa. Scientists have long been attempting to develop schematic and mathematical theories to explain the observed phenomenon of bush encroachment, and several theories were proposed and developed. The well-regarded theories include: (1) Waiter's two-layer model, (2) Moir's one-layer model, (3) state-and-transition theory, (4) equilibrium theory, (5) disequilibrium theory, and (6) non-equilibrium theory. Within those theories, the most frequently-indicated driving factors that explain bush encroachment include over-grazing, availability of soil nutrient and moisture, elevated CO2 levels, frequency and intensity of fire, spread of seeds of woody species by livestock and wild animals. It should be stressed that couplings and interactions among diverse driving factors are more often at work in determining the condition of bush encroachment. To summarize, the effort in managing semi-arid ecosystems needs critical knowledge to understand the cause-effect relationships of underlying factors through integrated approach. Therefore, future research on encroachment of woody plants should be multi-discipline oriented and multi-partnership involved. 展开更多

What does“Beyond the Western Horizon”mean?What is the implications of“a deeper dialogue about our independent futures”?What is the connection between these two expressions?It seems that the latter is meant as response to the former.But how?The seven authors in this special issue attempt to answer these questions by drawing mainly on Walter Mignolo’s rethinking of the trends of“Rewesternization”and“Dewesternization”over the past decade and his champion of decolonial and spiritual turn based on the theoretical resources from non-Western world to make suggestions for educational research in the Anthropocene. 展开更多

Ever since Derrida's appropriation of Walter Benjamin's "The Task of the Translator," and the deconstruction of the traditional notion of translation as an unequivocal communication of meaning, "translation" has become a powerful conceptual means in many fields of the humanities to underscore the agency of the subalterns in the context of colonialism, imperialism, or globalization, and to emphasize historical contingency over against necessity. As a matter of consequence, however, the question of the historically specific condition of the possibility of such "translation" has been largely neglected. In this essay I will argue, that a profound understanding of the processes of social and cultural transformation, which have been conceptualized in terms of "translation," can not be achieved unless global capitalism and its specific temporal dynamics are taken into consideration more seriously. Finally, this approach will also enable us to re-read Benjamin, and to reassess the significance of his "Task" for a more powerful critique of a social formation, "which produces commodities." 展开更多

The problem is modeled in a cylindrical coordinate system. The main theme of the present analysis is to study the endoscopic effects on the peristaltic flow of the Waiter's B fluid. To the best of the authors' knowledge, no investigation has been made so far in the literatures to study the Walter's B fluid in an endoscope. Analytical solutions axe obtained using the regular perturbation method by taking 5 as a perturbation parameter. The approximate analytical solutions for the pressure rise and friction forces are evaluated using numerical integration. The effects of emerging parameters of the Waiter's B fluid are presented graphically. 展开更多
