Satellite image data were used to detect, monitor and map different pollutants at five study sites along the El-Gamil beach, including El-Debba, El-Manasra, El-Fardous and El-Gamil inlets and the El-Gamil airport. The images were rectified and analysed by ERDAS IMAGINE 8.7. Image processing techniques were applied using ENVI 4.2 to analyse the SPOT image data (10 m resolution) for 2006. Image enhancement, principal component analysis (PCA), band ratios and supervised/unsupervised...

Africa Rice Center (WARDA) facilitated the development and translation of 11 rice videos. From 2005 to 2009, WARDA partners translated them into more than 30 African languages. Open-air video presentations enhanced learning, experimentation, confidence, trust, and group cohesion among rural people. The videos strengthened capacities of more than 500 organisations and hundreds of thousands of farmers. WARDA's integrated rural learning approach also helped women to access new markets and...

Through an examination of global climate change models combined with hydrological data on deteriorating water quality in the Middle East and North Africa (MENA), we elucidate the ways in which the MENA countries are vulnerable to climate-induced impacts on water resources. Adaptive governance strategies, however, remain a low priority for political leaderships in the MENA region. To date, most MENA governments have concentrated the bulk of their resources on large-scale supply side projects...

Malaria is rampant in Africa and causes untold mortality and morbidity. Vector-borne diseases are climate sensitive and this has raised considerable concern over the implications of climate change on future disease risk. The problem of malaria vectors (Anopheles mosquitoes) shifting from their traditional locations to invade new zones is an important concern. The vision of this study was to exploit the sets of information previously generated by entomologists, e.g. on geographical range of...

Prevalence of Schistosoma haematobium infections was assessed among 160 students of Twohofo Holy International School, Cape Coast, Ghana.Overall prevalence was 34.4%, with males and females having prevalence of 32.3% and 35.8% respectively.Age group 6-8 years had 30% while 24.2% were infected in age group 9-11 years.Prevalence was 48% in age group 12-14 years and 50% in age group 15-17 years.Parental occupation had effect on prevalence with children of self employed parents showing...

A cross-sectional survey of visual impairment (VI) was undertaken in the Enemor district in Southern Ethiopian where five years of trachoma control programme has been implemented using the SAFE (Surgery, Antibiotics, Face washing, Environmental hygiene) strategy. The prevalence of VI (presenting visual acuity in the better eye < 6/18) in 451 people above 40 years of age was 22% (CI: 17.6 to 27.6) and most of it was accounted for by cataract (67%) and trachoma (13%). Whereas cataract remains...

Climate change and human pressure on water resources make water management policies primordial in the agenda of policy makers. I first propose a literature review of the works on Water Computable General Equilibrium (CGE) Models suggesting the following classification: (i) competition between sectors; (ii) water pricing policies and tariffs; (iii) water and trade issues; (iv) CGE and other models. Secondly, the effects of droughts on the Kenyan economy are studied by means of a static CGE...

This study on the prevalence of urinary schistosomiasis and concomitant urinary tract pathogens was carried out between August and December, 1998, among school children in Ibadan North Local Government Area.Terminal urine sample collected from only pupils in classes 3 to 6 for the study were analyzed accordingly using the methods as described.Of the 1600 pupils examined, 920 (57.5%) who had the ova of Schistosoma haematobium also had pyuria; 75.4% of which had concomitant bacteriuria.There...

There are gaps in teacher preparation in Nigeria, such as limited contents of teaching subjects as well as deficiencies in pedagogy and length of practice, which affect the quality of instruction in Nigerian schools. There is, therefore, need for the supervisor, who should be knowledgeable, committed and tactful enough to sense teachers’ failings, suggest appropriate solutions and evaluate the progress of corrective programmes, in order to achieve improved school instruction. This paper...

This report demonstrated that the key for success in a globalized world lies increasingly in how effectively a country can assimilate the available knowledge and build comparative advantages in areas with good growth prospects and how it can use technology to address the most pressing environmental challenges. Higher-level institutions in Sub-Saharan Africa that is equipped to impart quality education and conduct relevant applied research can play a critical role in producing workers with...

Abstract Background Applying the switch from presumptive treatment of malaria to new policies of anti-malarial prescriptions restricted to parasitologically-confirmed cases is a still unsolved challenge. Pragmatic studies can provide data on consequences of such a switch. In order to assess whether restricting anti-malarials to rapid diagnostic test (RDT)-confirmed cases in children of between five and 15 years of age is consistent with an adequate management of fevers, a school-based study...

The study was carried out to find out the disposition of 2006 level 100 distance education students of the Winneba Study Centre towards success in their first university examination.In all 100 students responded to items in a questionnaire.The results indicated that few days before the examination respondents had occasional memory loss and the phenomenon of forgetting easily (mean of 1.55).Also, the night before their first paper respondents had about six hours' sleep (mean of 2.11).In the...
