Abstract This study focuses on the compound pahoehoe lava flow fields of the 2000 eruption on Mount Cameroon volcano, West Africa and it comprehensively documents their morphology. The 2000 eruption of Mount Cameroon took place at three different sites (sites 1, 2 and 3), on the southwest flank and near the summit that built three different lava flow fields. These lava flow fields were formed during a long‐duration (28th May–mid September) summit and flank eruption involving predominantly...

To investigate whether children in households involved in a participatory agriculture and nutrition intervention had improved growth compared to children in matched comparable households and whether the level of involvement and length of time in the project had an effect on child growth.A prospective quasi-experimental study comparing baseline and follow-up data in 'intervention' villages with matched subjects in 'comparison' villages. Mixed model analyses were conducted on standardized...

Eclampsia is the commonest direct cause of maternal death in South Africa. The latest Saving Mothers Report (2005-2007) indicates that there were 622 maternal deaths due to hypertensive disorders of pregnancy. Of these, 334 (55.3%) were due to eclampsia; of the eclamptic deaths, 50 were over the age of 35 years and 83 were under 20 years old. Avoidable factors involved patient related factors (mainly delay in seeking help), administrative factors (mainly delay in transport) and health...

The importance of the role of language in teacher education programmes and in children’s learning is crucial. This study focuses on the use of English as the language of learning and teaching and its impact on the language development of English second language (ESL) student teachers and ESL learners. Against the background of major theories in second language (L2) acquisition and learning, this topic is contextualized within the South African education system. An empirical inquiry was...

A group of children aged 6–17 years was recruited and followed up for 12 months to study the impact of schistosome infection on malaria parasite prevalence, density, distribution and anemia. Levels of cytokines, malaria specific antibodies in plasma and parasite growth inhibition capacities were assessed. Baseline results suggested an increased prevalence of malaria parasites in children co-infected with schistosomiasis (31%) compared to children infected with malaria only (25%) (p = 0.064)....

There is widespread agreement that professional development (PD) is the best possible answer to meeting the complex challenges in education systems. Studies on educational effectiveness identify the link between quality teachers and their PD. The purpose of this exploratory study was to determine the perceptions of Nigerian delegates from independent schools of the effectiveness of a training programme conducted by academic staff at the University of South Africa (Unisa). A mixed-method...

Recent satellite-based studies have revealed that the northern sub-Saharan African (NSSA) region has one of the highest biomass-burning rates per unit land area among all regions of the world. Because of the high concentration and frequency of fires in this region, with the associated abundance of heat release and gaseous and particulate smoke emissions, biomass-burning activity is believed to be a major driver of the regional carbon, energy, and water cycles. We acknowledge that the rainy...

Background: Health impacts related to climate change are potentially an increasing problem in Cameroon, especially during hot seasons when there are no means for protective and adaptive actions. Objective: To describe environmental conditions in schools and to evaluate the impact of heat on schoolchildren’s health during school days in the Cameroon cities of Yaounde´ and Douala. Methods: Schoolchildren (N285) aged 1216 years from public secondary schools completed a questionnaire about their...

Adoption rates of improved or modern varieties (MV) of sorghum in eastern Ethiopia are generally low. Although these MV may represent an effective means of coping with droughts, given their early maturing traits, landraces could prove to be more drought-tolerant and better adapted to marginal production conditions. Whether MV adoption is a risk reducing technology is very much an empirical question which this article investigates using a unique dataset from eastern Ethiopia in a year of...
