The marula tree (Sclerocarya birrea subsp. caffra), a common species in sub-Saharan Africa, grows naturally in both protected and communal land. Although considerable research has been undertaken on these trees in southern Africa, to the authors’ knowledge, the attitudes of local communities towards the protection of marula trees, particularly in communal land, has not been researched. This study intends to fill this gap in knowledge by examining the attitudes of local people towards conservation of marula trees. Studying the attitudes of people can provide insights on how they behave and how they are willing to coexist with S. birrea. The case study is set in Limpopo Province of South Africa in the villages of Ha-Mashau (Thondoni) and Ha-Mashamba where marula trees grow naturally. To fulfil the aim of this study, door-to-door surveys were carried out in 2018 and questionnaire interviews were used as the main data collection tool in 150 randomly selected households. The study revealed that local communities in the study area had positive attitudes towards conservation of marula trees. Strategies that are used by local communities to protect marula trees in communal land are discussed.

Food waste is becoming an important issue in light of population growth and global food security concerns. However, data on food wastage are limited, especially for developing countries. Global estimates suggest that households in developed countries waste more food than those in developing countries, but these estimates are based on assumptions that have not been tested. We therefore set out to present primary data relating to household food waste disposal for South Africa within the sub-Saharan African context. As the Gauteng Province contributes about 45% of the total municipal waste generated in South Africa, the case study area covers two of the large urban metropolitan municipalities in Gauteng, namely Ekurhuleni and Johannesburg, with a combined population of 8.33 million, representing nearly 15% of the South African population. Municipal solid waste characterisation studies using bulk sampling with randomised grab sub-sampling were undertaken over a 6-week period during summer in 2014 (Johannesburg) and 2016 (Ekurhuleni), covering a representative sample of the municipal waste collection routes from households in each of the two surveyed municipalities. The food waste component of the household waste (excluding garden waste) was 3% in Ekurhuleni and 7% in Johannesburg. The results indicate that an average of 0.48 kg (Ekurhuleni) and 0.69 kg (Johannesburg) of food waste (including inedible parts) is disposed of into the municipal bin per household per week in the two municipalities, respectively. This translates into per capita food waste disposal of 8 kg and 12 kg per annum, respectively, in South Africa as compared to the estimated 6–11 kg per annum in sub-Saharan Africa and South and Southeast Asia.

Internal Knowledge

This article reports on a study that investigated the impact of organisational culture on internal knowledge production and assessed the challenges of producing knowledge at the Africa Institute of South Africa (AISA), which is seen as a model knowledge producing think tank in sub-Saharan Africa. The broad objectives of the study were: identifying AISA’s achievements in knowledge production; finding out the challenges AISA confronts in producing knowledge; examining how AISA’s organisational culture impacts on internal knowledge production; and suggesting ways in which knowledge production at AISA and other think tanks may be improved. A case study was conducted and self-administered questionnaires, face-to-face interviews, document analysis, and observation were used to collect data. The findings showed that AISA’s knowledge production efforts are confronted by several challenges, including: organisational culture and employees’ negative attitudes towards sharing knowledge freely, and employees encountering difficulties in finding the information and knowledge they need. If these challenges could be identified and clearly confined, it is argued that AISA would be in a better position to effectively produce and utilise knowledge, enabling it to achieve its objectives more efficiently. It is recommended that AISA acquire knowledge from external sources; produce knowledge internally which it uses and is used by its clientele; and establish itself as a knowledge-based organisation by creating a knowledge friendly culture as a framework for addressing the issue of organisational culture. The study results will hopefully lay a foundation for understanding ways of improving knowledge production at AISA and thus influence positive public policy in sub-Saharan Africa.

This chapter presents a case study of the Nelspruit water concession completed in South Africa’s Mpumalanga Province in 1999. This is generally considered to be the third “classic” brownfield water concession in Sub-Saharan Africa (SSA), involving capital investment in system assets as well as commercial operation of the system by the private partner. The Nelspruit project exhibits most of the risks and shortcomings that helped account for the precipitous decline in private sector interest in such projects after the Asian financial crisis, as documented in Chapter 4. How did these risks and shortcomings materialize in Nelspruit? How were they dealt with and in what manner does the project continue to function after two decades? Why have there been no other prominent examples of similar “classic” water concessions in South Africa or in other SSA countries since 1999?

The purpose of this chapter is to compare industrial and urban growth policies in Sub-Saharan Africa (SSA) and North Africa (NA) with the aim to draw lessons and inform policy and research in the subject. The chapter advances the argument that industrial and urban growth ought to be directly related. This follows the development trajectory and urbanization trend in the Global South which was birthed and sustained by the Industrial Revolution. The case study approach has been used to develop this chapter where Africa is first divided into two broad territories, SSA and NA. Subsequently, cases are selected from Lusophone, Anglophone, and Francophone countries. The analysis considers in detail Zimbabwe, South Africa, Guinea-Bissau, Algeria, and Egypt.

Province Level

Sub-Saharan Africa (SSA) is a region of striking socio-economic and demographic diversities, characterized by an ongoing epidemiologic transition. Recent work shows that hypertension is of public health importance in SSA, particularly in urban areas, with evidence of considerable under-diagnosis, poor management and lack of communitywide preventive strategies. Our objective was to examine the spatial variation of predictors of hypertension at the province-level in South Africa, after accounting for individual risk factors such socio-demographics, lifestyle, and chronic co-morbidities. Our analysis was based on the 1998 South African Health and Demographic Survey (HDS), including 13,827 men and women aged 15 and over. Individual data were collected on self-reported lifestyle habits and chronic co-morbidities, but were aggregated to the current 52 health districts and 9 provinces in the country. We used a Bayesian geo-additive mixed model based on Markov Chain Monte Carlo techniques to map the spatial distribution of hypertension at the province-level, accounting for individual risk factors. The overall prevalence of hypertension (blood pressure ≥140/90 mm Hg) was 25.1%. In multivariable Bayesian geo-additive regression analyses, men [odds ratio (OR) & 95% Credible Region (CR): 1.29 (1.14, 1.44)], coloured [1.20 (1.01, 1.42)], current smokers [1.14 (1.03, 1.27)] and current drinkers [1.14 (1.01, 1.27)] were consistently associated with higher prevalence of hypertension. In spatial analyses, a significantly higher prevalence of hypertension was found in provinces with higher poverty and income inequalities [Free State: 1.34 (1.14, 1.62); North West: 1.33 (1.12, 1.58)]. To our knowledge this was the first study, which attempted to estimate the spatial variation of predictors of hypertension at the province-level in South Africa, after accounting for individual risk factors. Findings suggest distinct spatial patterns in hypertension prevalence in South Africa, pointing to the independent role of socio-economic disparities at the province-level, beyond individual-level risk factors for hypertension in this setting.
