- Description: One of the main features of South Africa’s law on remedies for breach of contract is the doctrine of election. In cases where a major breach has occurred, or a cancellation clause entitles the aggrieved party to seek cancellation, the aggrieved party has an election either to cancel or to claim performance, and will be held to that binary choice. In Primat Construction CC v Nelson Mandela Bay Metropolitan Municipality the Supreme Court of Appeal recently recognised an exception to the usual election rule, specifically in cases involving repudiation. In terms of the ‘repentance principle’, a party who experiences repudiation may initially seek performance in the hope that the breaching party will repent of their breach; but if it does not, the aggrieved party may then change its mind and seek cancellation. This essay considers the history of the doctrine of election and the path to the recognition of its qualifier, the repentance principle. Thereafter, the essay poses the question whether it remains desirable for the strict doctrine of election to continue to apply in South African law, bearing in mind that a strict election can have an unduly constraining effect on the interests of the non-breaching (or ‘innocent’) party. This analysis is informed by the broader policy considerations behind the recognition of the repentance principle; the fact that other analogous exceptions to the election rule do exist; and the fact that other jurisdictions do not adopt such a strict approach to the aggrieved party’s choice of remedy.

- Description: This paper describes how Changing Practice courses, developed by environmental activists in South Africa and based on social learning practice, have seeded cognitive justice action. For the educator-activists who facilitated these courses, it became apparent that we needed a bold emancipatory pedagogy which included cognitive justice issues. This enabled us and the activist-researcher participants to understand the extent to which local, indigenous, and spiritual knowledge had been excluded from water governance. The paper investigates how participants in the ‘Water and Tradition’ change project, established by the Vaal Environmental Justice Alliance (VEJA, engaged with cognitive justice, to demonstrate how African spiritual practice offers a re-visioning of the natural world. Finally, using the tools of critical realist theory, the paper reviews how VEJA bring about transformative social action through their participation in the Changing Practice course.

- Description: Egeria densa Planchon (Hydrocharitaceae) is a submerged macrophyte native to South America. It forms part of a new suite of invasive aquatic plants that has benefited from open nutrient-rich freshwater systems following the successful biological control of floating aquatic plants in South Africa. The specificity of the leaf-mining fly, Hydrellia egeriae Rodrigues (Diptera: Ephydridae) was tested, using traditional laboratory host-specificity testing (i.e., no-choice and paired choice). Only one non-target species, Lagarosiphon major Deeming (Hydrocharitaceae) supported larval development during pair-choice tests. In order to avoid the rejection of a safe and potentially effective agent, continuation (i.e., multiple generations) tests were conducted to measure the ability of the non-target species to nutritionally support a population indefinitely. None of these species could sustain a viable agent population for more than three generations. Laboratory host-specificity tests are limited as they exempt certain insect-host behaviours. To enhance the interpretation of host-specificity results, a risk assessment was conducted using agent preference (i.e., choice tests) and performance (i.e., choice and continuation tests) results. The feeding and reproductive risk that H. egeriae poses to non-target species is below 2%. Based on these findings, permission for its release in South Africa has been obtained.

- Description: The short term stability of efavirenz-loaded solid lipid nanoparticle and nanostructured lipid carrier dispersions was investigated. Hot High Pressure Homogenization with the capability for scale up production was successfully used to manufacture the nanocarriers without the use of toxic organic solvents for the first time. Glyceryl monostearate and Transcutol® HP were used as the solid and liquid lipids. Tween® 80 was used to stabilize the lipid nanocarriers. A Box-Behnken Design was used to identify the optimum operating and production conditions viz., 1100 bar for 3 cycles for the solid lipid nanoparticles and 1500 bar for 5 cycles for nanostructured lipid carriers. The optimized nanocarriers were predicted to exhibit 10% efavirenz loading with 3% and 4% Tween® 80 for solid lipid nanoparticles and nanostructured lipid carriers, respectively. Characterization of the optimized solid lipid nanoparticle and nanostructured lipid carrier formulations in relation to shape, surface morphology, polymorphism, crystallinity and compatibility revealed stable formulations with particle sizes in the nanometer range had been produced. The nanocarriers had excellent efavirenz loading with the encapsulation efficiency >90%. The optimized nanocarriers exhibited biphasic in vitro release patterns with an initial burst release during the initial 0–3 h followed by sustained release over a 24 h period The colloidal systems showed excellent stability in terms of Zeta potential, particle size, polydispersity index and encapsulation efficiency when stored for 8 weeks at 25 °C/60% RH in comparison to when stored at 40 °C/75% RH. The formulations manufactured using the optimized conditions and composition proved to be physically stable as aqueous dispersions.

- Description: Current global change scenarios predict an increase in atmospheric CO2 from the current 380 ppm to a value ranging from 540 ppm to 960 ppm by the year 2100. The effects of three air CO2 levels (400, 600 and 800 ppm) on five submerged aquatic plants that utilize HCO3− were studied, using the elevated CO2 Open Top Chamber facility at Rhodes University (Grahamstown, South Africa). Plants grew in water with two different initial dissolved inorganic carbon (DIC) concentrations of 1.5 and 3.0 mM. Overall, the growth rates and biomass allocation to roots were not affected by the initial DIC and air CO2, even though differences between the species were found. Furthermore, no overall effects were found on net photosynthesis, chlorophyll and starch content, even though significant effects of CO2 and DIC were observed in some species. In contrast, with increasing DIC and air CO2 a significant global decline in leaf nitrogen content linked with an increased C:N molar ratio was observed. The results indicate that submerged aquatic HCO3− users will be less affected by atmospheric CO2 increases when growing in DIC rich waters, in comparison to obligate CO2 users growing under CO2 limiting conditions as documented in previous studies. However, the changes found in plant nitrogen illustrate that atmospheric CO2 increases will affect nitrogen absorption by submerged plants, with subsequent ecosystem level effects.

- Description: This chapter argues that a transformative approach is necessary, involving radical economic change towards environmental sustainability and social justice – conceived of as two sides of the same coin, rather than opposing forces. It provides conceptual framings for the change processes required that are to be found in a relational philosophy and complex systems thinking applied to a broader vision of the economy, including a framing of environmental sustainability as a social justice issue, and viewing the changes needed through a transitioning systems lens. New industries must be developed in a socially inclusive manner and workers will need re-skilling for different jobs. A new development path requires concerted interventions including aligned skills development. In the face of dire socio-economic issues, environmental concerns have been deemed less important, and juxtaposed as being in competition with poverty eradication and employment creation. Humanity surely does have the creativity to design different social, cultural and economic systems over time, suitable for different contexts.

- Description: Silver triangular nanoprisms were synthesized and conjugated to zinc (ZnPc) and indium (InPc) phthalocyanines prior to embedding in asymmetric membranes. Conjugation of nanoparticles increased triplet state and singlet oxygen quantum yields of the phthalocyanines as well as enhancing photodynamic antimicrobial chemotherapy (PACT) activity against bacteria (S. aureus). The ZnPc derivative showed higher PACT activity when compared to the InPc, possibly due to degradation of the latter in aqueous media.

- Description: An isocratic high-performance liquid chromatographic method using electrochemical detection (HPLC-ECD) for the quantitation of clarithromycin (CLA) was developed using Response Surface Methodology (RSM) based on a Central Composite Design (CCD). The method was validated using International Conference on Harmonization (ICH) guidelines with an analytical run time of 20 min. Method re-validation following a change in analytical column was successful in reducing the analytical run time to 13 min, decreasing solvent consumption thus facilitating environmental and financial sustainability. The applicability of using the United States Pharmacopeia (USP) method scaling approach in place of method re-validation using a column with a different L–designation to the original analytical column, was investigated. The scaled method met all USP system suitability requirements for resolution, tailing factor and % relative standard deviation (RSD). The re-validated and scaled method was successfully used to resolve CLA from manufacturing excipients in commercially available dosage forms. Although USP method scaling is only permitted for columns within the same L-designation, these data suggest that it may also be applicable to columns of different designation.

- Description: In the concluding section of the book, this penultimate chapter elaborates on the central quest for research design that approaches green skills questions as inextricably linked to complex economic, environmental and social justice contexts that are systemic and emergent in nature, therefore necessitating a depth ontology and a dialectic approach, given the transformative intent of researching towards a more just and sustainable society. The chapter highlights methodological insights from the studies reviewed in this book, and provides guidance for green skills research design. It does so in relation to four interacting domains that research and programme planners need to consider in relation to each other. These are: the political-institutional context; theory and conceptual considerations; researchers’ personal-professional commitments; and the aligned methodological considerations. The meta-theory underlabouring the work in this book is Bhaskar’s dialectical critical realism, and its practical implications are illustrated and elaborated here with reference to the most pertinent features including lamination, systems, emergence, absence and associated approaches to analysis. The result is not a blueprint for a single research design, but considerations that could give rise to a variety of different designs for green skills research.

- Description: In this study, novel silicon (IV) phthalocyanine axially di-substituted with benzimidazole moieties (3) and its quaternized derivative (4) have been synthesized and fully characterized. The photophysical and photochemical properties of both phthalocyanines such as absorption, fluorescence and, singlet oxygen quantum yields, triplet state quantum yields and exited state lifetimes were investigated in solutions. These new silicon phthalocyanines exhibited low fluorescence but produced high singlet oxygen yields in both DMSO (compound 3 and 4) and aqueous media (compound 4). The quaternization of Si(IV)Pc (3) improved the triplet state quantum yield (ΦT) 0.61 to 0.83, consequently singlet oxygen generation (ΦΔ) increased to 0.69 from 0.42. Photodynamic antimicrobial chemotherapy activities (PACT) of Si(IV)Pc photosensitizers were determined towards Staphylococcus aureus. The higher efficiency was obtained with cationic derivative (4) giving reduction percentage value of 99.75%.

- Description: Two Sn(IV) triarylcorroles were synthesised and characterized. The absorption spectrum of a meso-thien-2-yl substituted tin(IV)corrole (1-Sn) is red shifted compared to its phenyl analogue (2-Sn) and shows no sign of aggregation in solution. 1-Sn and 2-Sn exhibited singlet oxygen quantum yields of 0.87 and 0.54 in DMF, and have a triplet lifetime of 31 and 50 μs, respectively. Time dependent cellular uptake in MCF-7 cells for 1-Sn reached a peak at 24 h, and 1-Sn was found to be more lipophilic than 2-Sn. 1-Sn showed good photo-cytotoxicity on exposure to a Thorlabs 625 nm LED with an IC50 value of 3.2 μM and remained inactive in the dark.

- Description: Water hyacinth is considered the most damaging aquatic weed in South Africa. The success of biocontrol initiatives against the weed varies nation-wide, but control remains generally unattainable in higher altitude, temperate regions. Eccritotarsus catarinensis (Hemiptera: Miridae) is a biocontrol agent of water hyacinth that was first released in South Africa in 1996. By 2011, it was established at over 30 sites across the country. These include the Kubusi River, a site with a temperate climate where agent establishment and persistence was unexpected. This study compared the critical thermal limits of the Kubusi River insect population with a laboratory-reared culture to determine whether any physiological plasticity was evident that could account for its unexpected establishment. There were no significant differences in critical thermal maxima (CTmax) or minima (CTmin) between sexes, while the effect of rate of temperature change on the thermal parameters in the experiments had a significant impact in some trials. Both CTmax and CTmin differed significantly between the two populations, with the field individuals tolerating significantly lower temperatures (CTmin: −0.3°C ± 0.063 [SE], CTmax: 42.8°C ± 0.155 [SE]) than those maintained in the laboratory (CTmin: 1.1°C ± 0.054 [SE], CTmax: 44.9°C ± 0.196 [SE]). Acclimation of each population to the environmental conditions typical of the other for a five-day period illustrated that short-term acclimation accounted for some, but not all of the variation between their lower thermal limits. This study provides evidence for the first cold-adapted strain of E. catarinensis in the field, with potential value for introduction into other colder regions where water hyacinth control is currently unattainable.

- Description: Since publication of the first record of Eichhornia crassipes in Cameroon in 1997, the weed has become highly invasive in the Wouri River Basin. Between June and September 2014, a socio-economic survey using participatory and qualitative methods was undertaken in the riparian villages of the Wouri River Basin to assess the perception of respondents to the presence of water hyacinth. The survey revealed that water hyacinth was a significant threat to activities along the river, which included fishing, sand extraction and river transportation. The presence of water hyacinth mats reduced catch rates of several common fish species, river transportation by 75%, and significantly reduced the income for sand extraction. Cameroon employs manual clearing of water hyacinth; however, respondents indicated they would consider other control methods, provided they do not have any negative impacts.

- Description: The relationship between diversity and resilience is relatively well‐established for ecological systems, but remains much less explored for socio‐economic systems. Institutional diversity can have particular relevance for protected areas, whose managerial responses to environmental change depend on their legal basis, ability to make and enforce rules and socio‐political acceptance and endorsement. 2. Protected area expansion strategies are increasingly turning to private land con‐ servation to increase the configuration and connectivity of national protected area networks. Yet, we know little about the relative role of privately owned pro‐ tected areas in protecting threatened and poorly protected (under‐represented) habitats, and in the overall connectivity of the national protected area network. 3. We present an empirical assessment of protected area tenure diversity across South Africa.

- Description: In South Africa, there is extensive NTFP trade within communities and via external markets. However, there is a limited indication of the proportion of all households trading one or more NTFPs, and how it varies in relation to local context. Therefore, this study sought to establish the proportion of households trading in NTFPs in sites of different distances to urban markets and agro-ecological zones of South Africa. The results showed that about 6.4% households reported selling NTFPs for various reasons, with many (22%) citing the need to earn cash income and limited employment opportunities (16.9%). Even though the returns from trading NTFPs are relatively low, every earning is very important to many cash-strapped rural households. This was demonstrated by the fact that many sellers of NTFPs used their earnings to augment household income and cover their living expenses.

- Description: Views that protected area (PA) expansion relies predominantly on land purchased by government are increasingly being challenged. The inclusion of privately owned PAs (PPAs) in national conservation strategies is now commonplace, but little is known about their long-term persistence and how it compares to that of state-owned PAs. We undertook the first long-term assessment of the dynamics of a national system of terrestrial PPAs, assessing its growth, as well as its resilience to downgrading, downsizing, and degazettement (PADDD). Between 1926 and 2018, 6.2% of all private nature reserves established in South Africa were degazetted, compared to 2.2% of state-owned nature reserves. Privately owned PA growth exceeded that of state-owned PAs. Trends in PA establishment differed between privately owned and state-owned PAs, reflecting different legislative, political, and economic events. Our findings highlight the value of enabling legislative environments to facilitate PPA establishment, and demonstrate the potential of PPAs as a long-term conservation strategy.

- Description: Handicrafts made in Kenya are popular with tourists and provides income to many artists. One such artist is Joseph Morris Njau Mung’othi, who renamed himself Morris ‘Foit’ out of respect for a Czech professor, Francis Foit who mentored him. The use of natural materials [non-timber forest products (NTFP)] for making handicrafts is common, but what is less common is the use of dead wood for making sculptures. This is a case study of a Kenyan sculptor who uses deadwood for carving, and has risen out of poverty by selling his art. He educated his five children and accumulated assets including a two-storeyed house-cum-studio and a car. Furthermore, his art gave him opportunities to travel to Uganda, Botswana and the United States. He is also the founder of an art center in Nairobi called the Kuona Trust, which supports local artists to exhibit and sell their work. This case study clearly demonstrates how the use of a NTFP product (in this case deadwood) helped Foit’s family rise above poverty.
