- Description: We analyse the impact of failing to control invasive alien plants (IAPs) on the water supply to the Berg River and De Hoop Dams, in other words, the opportunity cost of not clearing IAPs in these two catch-ments. To do this we used models to assess and compare the impact of current and future invasions on inflows into the dams. Although the clearing of current invasions would only provide a modest increase in the amount of water compared to, for example, the construction of an-other dam, failure to clear the invasion will have a negative impact on water security in the long term. We estimated that the Berg River Dam could lose up to 51% of its mean annual inflows to IAPs over a 45-year period, and the De Hoop Dam catchment could lose up to 44%. These impacts would continue to increase over time, and the costs of control could become very high as the plants invade rugged terrain. Major in-frastructural development requires Ministerial approval, supported by advice from senior officials. We suggest that such advice should sub-stantively take sufficient account of the benefits of clearing existing in-vasions, or at least of preventing further invasions. Our results suggest that serious consequences arise from insufficient investment in catch-ment management. An integrated approach to the management of the supply of and demand for water, that ensures long-term sustainability, is essential in informed decision-making and the early control of IAPs is a key component of that approach.

- Description: China’s impact and role in the development of countries in Africa, primarily through foreign direct investments and grants to governments, has increased in the past decade. For instance, the total value of trade between China and Africa was USD198.5 billion in 2012, increasing to USD385bn in 2015 (African Economic Outlook, 2014, p. 76). A growing number of Chinese private and governmental organisations are investing in southern Africa. In Tanzanian contexts, this leads to a close collaboration of Chinese and Tanzanian employees (African Economic Outlook, 2014). These collaborations in Chinese organisations in Tanzania lead to intercultural communication situations and to new intercultural experiences and perceptions.

- Description: The cooperation between Chinese and Tanzanian employees and organisations has a very long tradition in Tanzanian history. The purpose of this paper is to explore and understand how Chinese and Tanzanian employees see themselves and “the other” while cooperating. This research presents a study of a single case, conducted in a selected Chinese organisation in Tanzania. It uses a hermeneutical research paradigm. Data was collected using semi-structured interviews and observation and analysed through content analysis, following Terre Blanche’s model. Findings demonstrate and explain the perspectives which Chinese and Tanzanian employees hold mutually with regard to the group image of self and other within the organisation, as well as perceptions of self and other in terms of organisational, environmental and cultural contexts. Since this is a qualitative single organisational case study, the findings are limited to this single organisation and are not generalisable. Conclusions drawn from the new research insights are provided and recommendations are given in terms of how Chinese and Tanzanian perceptions present themselves and how organisations could work with self-image and counter images to improve intercultural cooperation.

- Description: During the past decade, publications and conferences on management in African organisations (Kamoche 2011a; 2011b) and in global contexts (Mangaliso 2001; Jackson 2004)1 have increased steadily. In various African contexts and organisations, job satisfaction (JS) (Walumbwa et al. 2005) and organisational commitment (OC) (Gbadamosi 2003; Wasti 2003; Nyengane 2007; Pillay 2008) have been researched. Most of the previous research is quantitative in nature. Although quantititative research provides insights into the relationships between variables, it does not necessarily provide in-depth meaningful conclusions on micro-psychological levels (e.g. Sempane, Rieger & Roodt 2002; Buitendach & De Witte 2005).
