    Community perceptions of climate change and vanability impacts in Oshana and Ohangwena Regions
    (University of Namibia, 2012) Kaundjua, Maria B.; Angula, Margaret; Angombe, Simon T.
    The links between climate change, social and economic development, health, and environmental sustainability have become a dominant and urgent global concern. Understanding community perceptions leads to successful adaptation to climate change. This paper analyses community perceptions of climate change in selected Namibian regions. The study applied the qualitative research approach using the focus group discussion method. The data collection was conducted within a Socio-economic and Gender Analysis framework. The study has revealed that the communities are aware that the climate is changing due to changes observed in the past three to four decades. However, the study concluded that the communities do not have an adaptive capacity to respond to catastrophic natural disaster events such as the recurrent floods of 2009, ww & 2011. The study recommends a programme on community awareness regarding climate variability and change and its implications. The government in collaboration with communities and other relevant stakeholders should set up a long-term adaptation strategy for Namibia.

    Evaluation of drought indices using the 40-percentile threshold for the north-central regions of Namibia.
    (University of Namibia, 2012) Angombe, Simon T.
    Drought is not uncommon to the Southern African climate and it has become a matter of serious concern in Namibia. For that reason, almost all parts of Namibia have become vulnerable to drought occurrence. Whilst recognising agriculture as a pertinent component of the Namibian economy, it is imperative to underscore the importance of drought early warning products for short- and long-term decision making in various sectors of the country’s economy. Following the 1991/92 drought, which ravaged more than 80% of Southern Africa, Namibia now realise the value of meteorological information in weathersensitive decisions. This severe drought has been described as the worst in living memory. Five stations (Ombalantu, Oshakati, Rundu, Katima Mulilo and Tsumkwe) in the northern part of Namibia were assessed. The researcher used the rainfall decile method to assess drought conditions by evaluating whether the widely used 40-percentile threshold is appropriate for triggering a drought warning in Namibia. Results showed that the threshold might have been set too high to be of use in warning farmers of coming droughts. In order to determine the percentile that would be best serve as trigger for drought warnings, there is need for further examination at 30, 25 and 20 percentile mark thresholds. Based on the 40-percentile threshold, much of the drought and a decrease in rainfall accumulation in Ombalantu and Oshakati in the Omusati and Oshana regions respectively, occurred towards the end of the 20th century.
