Abstract: Aim: To quantify current and predict future distribution of the citrus greening pathogens “Candidatus Liberibacter asiaticus” (Las) in Africa and “Candidatus Liberibacter africanus” (Laf) globally. Location: Africa. Methods: Three species distribution models (MaxEnt, BIOCLIM and Boosted Regression Trees) were used to predict the current and future potential distribution of Las in Africa, and the potential global distribution of Laf, using long-term bioclimatic variables. Tw...
The Environmental Kuznets Curve (EKC) hypothesis is a presumption that environmental degradation follows an inverted U-shaped trajectory in relation to economic growth. The thorny question of whether economic growth could provide a cure to environmental degradation has sparked off a large body of empirical studies in the last decade. The conclusions have been mixed. This study contributes to the debate on the existence and empirical test of the EKC for Nigeria by applying Ordinary least Squar...
Developing countries, of which Ghana is no exception have actively engaged in trade openness after independence, yet, their economic growth remains low and this calls for urgent attention to address the situation. This study therefore examines the impact of trade openness on economic growth of Ghana for the period 1984–2018 taken into consideration the role quality of institutions play. The results from the autoregressive distributed lag model (ARDL) reveal that, both trade openness and qua...
Abstract: The conservation of biotic diversity is a growing challenge within southern Africa at the beginning of the 21st century. Growing populations and trends toward a questionable Western development model place demands on the use of land for food, fiber, and fuel production. The traditional establishment and use of formal conservation areas is being challenged against the needs of humans and the past unbalances created by colonial rule. Conservation areas, as isolated islands in a sea o...

Significant effort has been put into the development of cost-effective abalone cultivation systems in South Africa, but the limited availability of suitable seaweed for abalone food is an obstacle to future development. The aim of this study was to investigate whether land-based integrated aquaculture (tank cultivation) and seaweed culture using Ulva lactuca in aquaculture effluent was feasible. This study was carried out at two abalone farms: Danger Point (I & J) (140 km east of Cape Town) a...
Abstract: The unbalance application of the hydropower and others renewable energy generation in west Africa, constant rise in the demand of energy, which leads to damping in the electricity supply and the importance of reducing greenhouse emissions, has brought the adoption of clean renewable energy sources for generation of electrical power. One of these sources that have the potential to supply the world’s energy needs is the ocean (Home of waters). The current utilization of ocean area...

Gombe 2018 Abstract Most countries strive to attract foreign direct investment (FDI) because of its acknowledged advantages as a tool of economic development. Africa – and Nigeria in particular – joined the rest of the world in seeking FDI as evidenced by the formation of the New Partnership for Africa’s Development (NEPAD), which has the attraction of foreign investment to Africa as a major component.The main objective of this study is to establish quantitative relationships among the ...
ABSTRACT Regional integration scholars have written extensively on the role culture plays in the overall success or otherwise of regional integration the world over. The role of culture in the integration of Africa has also received some attention. The Economic Community of West African States (ECOWAS) in 1987, realizing the importance of culture to regional integration, and accepting that the ECOWAS region had such cultural diversity that could be harnessed for the good of the subregion, p...
INTRODUCTION The return of the National Theatre-Sponsored television epic, (1) 'Roots' on the, Nigerian Television screen, in 1992 was anything but a coincidence. The timing oft the return clearly shows how far television can be used to whip up national sentiments in support of the crusade for reparations for the 'injustices' done Africa and Africans during the over four hundred years of slavery and slave trade. , , No doubt, 'Roots' is a moving recapture of those terrible days. No one in his...

Ethiopia has historically played a significant role in the region's conflict resolution and peacekeeping efforts. Previous research has shown Ethiopi...
ABSTRACT In the last decade, the prevalence of malaria has been escalating at an alarming rate, especially in Africa. A recent estimate of malaria incidence derived from routine surveillance data suggest 174 million episode occurred in African region in 2011 with estimated deaths of 596,000 (WHO, 2011). Malaria has been estimated to cause 2.3% of global disease and 9% of disease in Africa (WHO, 1997); it ranks third among major infectious disease threats in Africa after pneumococcal acute res...
ABSTRACT Soybean (Glycine max. (L)Merril) is one of the most popular pulses in the world. It has been known to man for a long time since its first record goes as far as 2500 BC in China and Manchuria. Glycine max belongs to the subgenus soja, which also contains G. soja and G. gracilis. Soybean is grown primarily for the production of seed, has a multitude of uses in the food and industrial sectors, and represents one of the major sources of edible vegetable oil and of proteins for livestock ...
ABSTRACT Most economic rationale for granting special incentive for attracting foreign direct investment [FDI], is based on the belief that FDI bridges the “Ideal gaps” between the rich and the poor nations, in addition to the generation of technological transfer and spillovers. Empirical literature however finds controversial, the effect of FDI on productivity growth. This work contributes to the existing studies by applying correlation and causality test in exploring the possible links...
