- Description: The HIV and AIDS epidemic remains a major health concern among the Namibian population despite interventions to mitigate it. The creation of awareness about the epidemic through school curricula is one of the government’s interventions. However, the provision of Sexuality, HIV and AIDS education in schools today is based on adult ideas of what they feel is right for young people to learn. This leave learners vulnerable and inadequately supported regarding possible questions they may have in this context. With vast amount and variety of conflicting information available to young people regarding their sexuality; and how their sexuality can and should be expressed, some of this information leads them to engage in risky behaviours that exposes them to HIV infection. Hence the need to involve young people in the development of the curriculum, to meet their educational needs in context of sexuality, HIV and AIDS. In this study, evidence for including learners in the construction of educational content regarding sexuality education is sought. This qualitative study used a phenomenological research design, interpretive paradigm and a participatory arts-based research methodology. Drawings, Vignettes (Agony Aunt) and follow-up focus group discussions were used to generate data with junior and senior learners, aged 15-24, from two secondary schools situated in the Oshikoto region of Namibia. Bronfenbrenner’s ecological system theory and Vygotsky’s sociocultural theory underpinned and decipher the findings of this study. The findings revealed that the school curriculum has informed learners on Sexuality, HIV and AIDS matters. The data generated about what they want to learn revealed that there is a need for more information on matters of sexuality, HIV and AIDS, which are not provided by the current education system. The data also revealed that the information that young people are exposed to is mostly associated with myths and misconceptions. This study thus recommends that a more comprehensive sexuality education, which takes into account learners’ needs, be provided in order for them to be guided appropriately on issues concerning their sexuality in the context of HIV and AIDS, so that we can move towards as HIV free world.

- Description: As climatic conditions continue to change globally, there is a need to assess past environmental change in relation to changing water balance, temperature and sea-level. By understanding the extent of past environmental change, and how anthropogenic impacts have affected ecosystems, better and more accurate future predictions of change can be made. Through the use of the sedimentary record within coastal wetlands, geochemical, (organic content and stable isotopes) and biological (diatoms) proxies were utilised to determine; (i) the baseline water quality record for Soetendalsvlei, one of only a few coastal lakes in South Africa, (ii) the effect of agriculture and mouth manipulation of the Heuningnes Estuary on the microalgae ecology and (iii) the link between palaeo-salinity and trophic status on a regional basis between Soetendalsvlei and Groenvlei, situated 320 km apart. Present water quality and phytoplankton biomass and community structure were assessed for Soetendalsvlei and its associated wetlands, Voëlvlei and Waskraalsvlei to determine the current health of these systems and to obtain modern diatom analogues to be used in the palaeolimnological reconstruction of the coastal lake. Diatoms were not dominant during this study period. Chlorophytes and flagellates were the dominant phytoplankton groups throughout the different wetlands. With the exception of Voëlvlei, the wetlands were all in good health, although SRP concentrations were within the eutrophic to hypertrophic range and are cause for concern. In Voëlvlei, phytoplankton biomass was within the eutrophic range with chlorophyll a concentrations ranging between 20 – 400 ug.l-1 Cyanobacteria, a further indicator of eutrophic conditions, were dominant during the warmer summer periods. Rainfall and freshwater inflow had a significant effect on the biomass and composition of the phytoplankton and acted as a resetting mechanism for all the wetlands as water quality conditions improved thereafter. Comparisons of the water quality and phytoplankton community between the upper reaches of the Heuningnes Estuary and Soetendalsvlei, indicated that artificial breaching of the estuary mouth significantly impacted the connectivity between these two systems, with marine intrusion extending into the upper reaches, while freshwater conditions dominate in the coastal lake. Unfortunately for the palaeolimnological study diatom preservation was poor, however, geochemistry and stable isotope analyses did provide adequate evidence of marine transgression (~8000 yr BP and 4000-2000 yr BP) and regression events comparable to other South African sea-level models developed for the east and west coast. High organic matter content (i.e. higher trophic state) and estuarine POC (C4 vegetation) were associated with periods of marine regression, i.e. increased freshwater, whereas marine transgression events were associated with low organic content and marine POC and DOC. This is comparable to studies conducted in Uruguay (South America) where palaeo-salinity was related to trophic status, i.e. increased freshwater input was associated with high nutrients. Comparisons of the palaeo-record with recorded historical occurrences of droughts and floods, also provided a means of assessing the sedimentary record and to infer anthropogenic impacts after 1850 AD. Overall it can be concluded that coastal lakes of both continents in the Southern Hemisphere displayed similar trophic responses to sea-level fluctuations during the Holocene. This adds valuable information to global sea-level change models.
