Foreign Direct Investment: A Journey To Economic Growth In Ghana - Empirical Evidence

Foreign Direct Investment (FDI) has been viewed as a major stimulus to economic growth in developing countries. Its ability to deal with two major obstacles; namely, shortages of financial resources and technology and skills, has made it the center of attention for policymakers in low-income countries in particular. In spite of the significance generated by FDI flows, the flow to developing countries and the world, in general, has witnessed persistent decline over the years. The implication for the drop means that competition to attract FDI has increased as developing countries continue to create the enabling environment to attract foreign investors. Ghana, in particular, has, over the last decade, pursued various forms of economic reforms and liberalization of trade regimes in order to become more competitive in the international financial market. A handful of papers has recently dealt with FDI flows in Ghana. However, most of these studies are concerned with strategic FDI policy to attract FDI flows. The purpose of this study is to empirically determine the factors that influence FDI flows in Ghana, using time series data from 1988 to 2011. Regression analysis was carried out using relevant econometric techniques. The results of the study capture trade openness, exchange rate, natural resources, and infrastructure as the drivers of FDI in Ghana. Macroeconomic variables, such as inflation and per capita gross domestic products, were also registered to impact the determinants of FDI flows in Ghana. The contribution of this paper is that economic liberalization was found to be significant, indicating that policymakers' efforts in liberalizing the economic activities may necessarily translate into significant FDI inflows into the country

The Role of Maize Tassels in Amelioration of Heavy Metals from Contaminated Soils and its Effects on Vegetables.

Vegetables depend on water as solvent for their growth and have greater potential of accumulating in their edible parts heavy metals which are dangerous to human health.  Maize tassel was applied to soil to determine its role in removal of heavy metals such as Manganese (Mn), Iron (Fe), Cadmium (Cd) and Zinc (Zn) from the contaminated soil with cabbage as the test crop. The average mean concentration of the heavy metals after twenty one and fifty one days were; Mn (0.402 mg/kg and 7.427 mg/kg), Fe (0.894 mg/kg and 4.838 mg/kg) and Zn (0.155 mg/kg and 1.073 mg/kg) respectively. The concentration of cadmium in the wastewater sample used was 0.680mg/l, and its concentrations in tap water (<0.002mg/l), in soil (<0.002mg/kg) were below the detection limit. The enrichment factor for Mn, Fe and Zn in soil treated with maize tassel (T1) are 9.73, 10.70 and 5.23 respectively, whereas treatment without (T2) are 1.05, 1.86 and 4.52 respectively. The high enrichment of T1 is attributed to the availability of the active site within the tassel absorbent. Keywords: Heavy metals, maize tassel, contaminated soil, wastewater

Simulating the Impact of the Global Economic Crisis and Policy Responses on Children in Ghana

Like many countries in sub-Saharan Africa, Ghana is experiencing the impact of the global crisis and the uncertain economic outlook. Indeed, as Ghana’s economy is among the most open in Africa, it is expected that the country has been and will continue to be severely affected by the crisis, although strong export prices of its main exports (gold and cocoa) may at least partially counteract the effects associated with the crisis. The main goal of this paper is to understand the potential impacts of the 2008/9 global crisis on different dimensions of child poverty (monetary, hunger, school participation, child labour and access to health services) in Ghana and to support the policy-maker in designing the most appropriate policy response to counteract the negative effects of the crisis. As timely data are not available, a combined macro-micro economic model to predict the impact of the global crisis on children was developed. Simulations suggest that the financial crisis would increase monetary poverty and hunger across all regions of Ghana, eroding many of the gains made over the past few years. Indeed, in comparison with the year preceding the crisis, instead of a reduction of four percentage points in child monetary poverty in 2011 predicted in the absence of crisis, the simulations indicate a 6.6 percentage point increase, with a continuous increasing pattern over the period of study. The global crisis is also predicted to severely deepen hunger among children, which is simulated to increase up to 6.6 percentage points in 2011 beginning with a sharp increase already in 2009. For both monetary poverty and hunger, the impact of the crisis differs across all regions, with the Eastern, Volta and Greater Accra regions predicted to be the most affected. Children’s participation in schooling and labour, as well as their access to health services, are forecast to be much less affected by the crisis, although it is found to reverse predicted increases in enrolment and health access (with substitution toward more modern types of health services) and forecasted reductions in child labour. Finally, alternative policy options have been simulated: a cash transfer programme targeted to poor children is found to be generally more effective in protecting children than food subsidies. Indeed, with a total budget equivalent to 1% of 2008 GDP, a cash transfer – equivalent to an individual annual amount of 19.8 Cedis – would cut the predicted increase in monetary poverty by over two percentage points in 2011. Although Ghana might be in a position to rapidly implement a cash transfer programme building on the existing Livelihood Empowerment against Poverty (LEAP) programme, other interventions (or mix of policies) might be more cost-effective in the short run. A combination of a universal or regionally targeted cash transfer programmes for children aged 0 to 5 years old, together with a school-feeding programme in poorer regions, might represent an effective way to intervene quickly to improve child well-being.Global economic crisis, child poverty, hunger, education, child labour, health, West and Central Africa, Ghana, social protection

Assessment of contamination of singed hides from cattle and goats by heavy metals in Ghana

Many local butchers in Ghana have been using scrap tyres as substitute for firewood to singe slaughtered ruminants. This study analysed such singed hides from seven goats and three cattle in unregulated local slaughtering operations near the Kumasi abattoir, for risk of heavy metal contamination (Mg, Mn, Cu, Ni, Cd, Pb and Zn) using atomic absorption spectrometry. Relative to unsinged control hides, singed treatments generally elevated heavy metal levels in both goats and cattle hides. Magnesium, Mn, Cu, Ni and Cd concentrations in un-singed goats hide increased by 23, 29, 54, 24 and 20% respectively to 108.63 ± 3.85, 0.83 ± 0.13, 1.63 ± 0.13, 2.15 ± 0.29 and 2.26 ± 0.20 mg/kg in the singed material. Similarly, singeing increased Mg, Mn, Cu, Ni, Cd and Zn concentrations in cattle hide by 94, 49, 130, 33, 174 and 1055% to 80.0 ± 5.25, 2.13 ± 0.26, 5.67 ± 1.24, 3.50 ± 0.17, 4.20 ± 0.17, and 204.49 ± 36.69 mg/kg respectively. Lead concentration in cattle hide on the other hand decreased by 34% upon singeing, from 4.61 ± 0.30 mg/kg in un-singed controls to 3.06 ± 0.26 mg/kg in singed material. High concentrations of the metals in singed hides could not be entirely attributed to the singed treatment alone, in view of considerable background levels of heavy metals recorded in the un-singed samples; a situation that probably reflected a larger problem of heavy metal pollution in the local environment. Concentrations of Cd and Pb in hides were above maximum permissible levels (MPLs) of 0.05 and 0.01 mg/kg respectively set by the European Commission Regulation, whilst Zn was also above MPL of 50.0 mg/kg, according to the Meat Food Products Order of India. It was concluded that the hides were potentially unsafe for human consumption.Key words: Heavy metal contamination, meat products, singed treatments, consumed animal hide

Aqueous extract of Lannea microcarpa attenuates dextran sulphate-induced paw oedema and xylene-induced ear oedema in rodents

Background: Lannea microcarpa Engl. and K. Krause (Family Anacardiaceae), a tropical tree is used traditionally used in Africa for both medicinal and non-medicinal purposes. Folkoric uses of the plant include wound healing, conjunctivitis, stomatitis and gingivitis among others. Inflammatory reactions are involved in several diseases which this plant is traditionally used to manage. This study was therefore aimed at investigating the antiinflammatory effects of the aqueous extract of Lannea microcapa.Methods: Oedema was induced in the right hind paws of Sprague Dawley rats (200-250g, 12 weeks old, n=5) using dextran sulphate solution whiles ear oedema was induced in ICR mice (25-30g, 6 weeks old, n=5) using xylene solutions. Aqueous extracts of ALM (30, 100 and 300mg kg-1) were administered in a set of rats and mice for both prophylactic and therapeutic studies. In the dextran sulphate-induced paw oedema, rats (200-250g) were treated orally with ALM (30, 100 and 300 mg kg-1) for both prophylactic and therapeutic studies. The paw thickness of the rats was measured before and after dextran sulphate injection at an hourly interval for 5 h. For xylene-induced ear oedema, ICR mice (25-30g) were given the same doses of the ALM and the ear weight of mice were measured after 2 h.Results: In the dextran sulphate-induced paw oedema, the ALM reduced the mean maximal paw oedema significantly (P ≤0.05) to 36.392±9.207% and 26.050±3.396% at 100 and 300 mg kg-1 (prophylaxis) and 32.192±5.670%, 31.398±6.921% and 31.593±5.841% at 30, 100 and 300 mg kg-1 (therapeutic) in dose dependent manner when compared to the control respectively. Similarly, the ALM dose dependently showed a significant (P ≤0.05) reduction of percentage mean oedema in xylene-induced ear oedema by 43.56%, 59.63% and 68.07% at 30, 100 and 300 mg kg-1 when compared to the control respectively.Conclusions: Aqueous extract of Lannea microcapa (30 -300 mg kg-1) caused significant reduction of oedema in both dextran sulphate-induced paw oedema and xylene-induced ear oedema

Child protection in Ghana : Exploring the perception and behaviour of radiographers.

This study, which was in two Phases, sought to explore the cultural understanding amongst Ghanaian radiographers of the concepts of child abuse and child protection (Phase 1) and how they perceived and participated in child protection within the health system in Ghana (Phase 2). Data was collected using phenomenological methodology. Open ended questionnaires were used in Phase 1 and semi-structured interviews in Phase 2. Participants were radiographers who were selected using purposive sampling. Data was thematically analysed and managed with NVivo Version 10. Themes developed formed the basis of the discussion. Results showed that participants understood the concepts of child abuse and child protection differently. The majority of participants sought further information through history taking to gain insight into child's diagnosis. Participants were found to trade their professional values against their behavioural beliefs in culture and superstition by indicating the fear of spiritual attacks when they intervened to help a child. Participants reported barriers such as training deficits, lack of knowledge in reporting regulations, and the absence of a framework or structures in place to guide child physical abuse management. The results showed that the majority of participants were ignorant of the role of the social worker in identified child physical abuse. Additionally, there was no teamwork in the majority of the hospitals in the management of child physical abuse. From the various findings, this study argues that the apparent unanimity of child abuse definition was inconclusive in this setting. The meanings assigned to child protection by participants contradicted their behaviour towards child protection.Participants' behaviour towards child protection was congruent with the theory of panned behaviour and social exchange theory. Fear, lack of direction and collaboration characterised the management of child physical abuse

Genotype by environment interaction and stability of extra-early maize hybrids (Zea Mays L.) for yield evaluated under irrigation.

Maize (Zea mays L.) is the most important cereal crop produced in Ghana. However the change in environmental conditions, the expansion of maize to new agro-ecologies coupled with inadequate maize varieties available for the different environments affects yield improvement programmes in Ghana. Hence, the study is to investigate the influence of genotype by environment interaction on the maize hybrids and to identify stable and high yielding hybrids with superior agronomic for famers use in the country. The objectives of the study was to investigate the influence of genotype by environment interaction on the maize hybrids and to identify stable and high yielding hybrids with superior agronomic performance for famers use in Ghana. Thus, fifteen extra-early maize hybrids and three locally released checks were evaluated in a randomized complete block design with three replications in two locations in Ghana. The experiment was carried out at KNUST and Akomadan which represent the forest and forest transition zones of Ghana. Nine of the hybrids out of the fifteen hybrids evaluated produce above the average yield and the effect of genotype, location and genotype by location interaction was significant for grain yield. The GGE biplot used in this study revealed that TZEEI-1 x TZEEI-21, TZEEI-6 x TZEEI-21, TZEEI-15 x TZEEI-1 and TZEEI-29 x TZEEI-21 were high yielding and stable hybrids because they were closer to the ideal. The GGE biplot also identified Akomadan as the most ideal testing environment for these hybrids under irrigation

Incipient bifenthrin-resistance in field populations of cocoa mirids, Distantiella theobroma (Dist.) and Sahlbergella singularis Hagl. (Hemiptera: Miridae)

Bifenthrin is one of the insecticides approved by the Ghana Cocoa Board (COCOBOD) for the control of cocoa mirids. Bifenthrin-resistance levels of D. theobroma and S. singularis collected from different locations in the Eastern Region (ER), Volta Region (VR) and Central Region (CR) were determined by calculating their resistance ratios (RRs). The highest RRs for S. singularis were recorded from New Tafo in the ER and Logba Alikpati in the VR, which displayed 6-fold and 6.2- fold bifenthrin-resistance, respectively. Populations of S. singularis from Pankese in the ER and Likpe in the VR also displayed 3.6-fold and 3.9-fold bifenthrin-resistance, respectively. The D. theobroma population that displayed the highest bifenthrin-resistance of 3.7-fold was from New Tafo. The results show incipient bifenthrin-resistance in field populations of D. theobroma and S. singularis, which requires the implementation of effective resistance management strategies to prevent full-blown resistance in the cocoa mirids

INSECTICIDE HANDLING IN COCOA PRODUCTION IN FOUR REGIONS IN GHANA

Management of insect pests of cocoa (Theobroma cacao L.) using insecticides began in 1950 and has since gone through various programmes with concomitant challenges and successes. Presently Imidacloprid (Confidor®), Bifenthrin (Akatemaster®) and Thiamethoxam (Actara®)are recommended by Ghana Cocoa Board (COCOBOD) for the management of insect pests. A survey was conducted in the Ashanti, Eastern, Volta and Western Regions of Ghana using questionnaires and farm visits of 147 cocoa farmers’ fields to gather information on the characteristics of the farmers and insecticide handling and use by respondents. The survey showed that males dominated cocoa farming (72.7%) and most of them aged between 50 and 60 years. About 44% have had basic education whilst 37.5% of them belonged to farmer based organizations. About 52.8% of the farmers own motorized mistblower but 47.2% of the farmers use knapsack in the absence of a mistblower. About 44.8% do their own spray application whereas 55.2% hire labour. About 60.9% of the population across the regions read the label on the insecticides before application. A few (31.6 %) of the respondents put on the full personal protective costume during insecticide application and 21.9% do not use any protection. There was a positive correlation between farmers’ membership of farmer-based organisation and the costume-wearing farmers in the Ashanti, Eastern and Volta Regions and it was significant in the Ashanti region. It isrecommended that training and monitoring programmes be organized for farmers on the need to handle pesticides properly for personal and environmental safety and consumer benefit.Keywords: Insecticides; pest management; cocoa farmers; safet
