A Spatial Suitability Assessment of Maize and Tobacco in Response to Temperature and Rainfall Changes in Zimbabwe
(2022) Nkoma, Tsungai; Crespo, Olivier
Climate is changing, and this change poses threats to the agricultural sector. The impacts of climate are expected to become more extreme as the earth warms, and this change will affect climate suitability for different types of crops. The degree to which an increase in temperature patterns and rainfall variations will affect climate suitability for agricultural practices needs to be further understood. This can be achieved by performing a climate sensitivity analysis and contribute to informing adaptation policies and mitigation measures. This study aims to analyze the sensitivity of important crops in Zimbabwe, maize, and tobacco, in response to changes in temperature and rainfall patterns. This research paper used a sensitivity analysis of climate variables; rainfall, and temperature, using historical climate data derived from WorldClim for the period 1990-2018 to assess climate suitability. The historical climate data was used as the baseline to assess the sensitivity of maize and tobacco under a 2°C, 3°C, and 4°C temperature increase as well as a 5%, 15%, and 30% increase and decrease in annual average rainfall amount. The modified spatial climate data was computed in QGIS, and suitability was simulated using the Ecocrop model embedded in the DIVAGIS user platform. The results from this study indicated that in Zimbabwe, both crops are more sensitive to rainfall changes than to temperature changes (independently). A 5%, 15%, and 30% decline in the average rainfall will result in previously suitable areas becoming marginal, very marginal, and others unsuitable for both crops that are in agro-ecological regions I to III; i.e., provinces that include Mashonaland Central, Mashonaland West, Mashonaland East, Harare, and Manicaland. When crops are subjected to combined changes (temperature and rainfall), both crops become more sensitive. When exposed to high temperatures and low rainfall together, for instance, provinces such as Mashonaland Central, Mashonaland West, Mashonaland East, and Harare which are known as historically suitable areas for maize cultivation, will become marginal or very marginal. This change in suitability could have consequences not only on food security but also on people's livelihood and understanding the crops' sensitivity to climate changes helps support the well-being progress of the country.

Aerotropoli agriculture: a study of the Dube AgriZone at the Dube TradePort, KwaZulu-Natal
(2014) Cassim, Adila; Pirie, Gordon
The Dube AgriZone has been described as an agricultural cluster development zone situated at an air logistics platform called the Dube TradePort in La Mercy, KwaZulu-Natal. The Dube AgriZone was launched in 2012 and aims to stimulate the growth of KwaZulu-Natal's perishable goods sector by producing high-value fresh produce all-year round in high quantities for both domestic and international markets. The main objective of this study was to investigate the current performance status of the Dube AgriZone's operation. This research made use of data collected from key informant interviews, document analysis and observational recordings during site visits. The information was used to compile a case study of the Dube AgriZone as an example of agriculture at an airport precinct (aerotropoli agriculture). Findings of this research have shown that the Dube AgriZone has operated with some success and failure during Phase 1. Infrastructural, logistics, financial, market, climate and administrative issues at the farming facility surfaced during this investigation. This study advocates that more research is needed on how to assist the Dube AgriZone project to operate optimally combating the current issues that it faces. It is hoped that this research can offer an interesting contribution to information on agricultural projects situated at airport precincts.

Assessing the effectiveness of Environmental Impact Assessment as a safeguard to biodiversity in the Cape Floristic Region of South Africa
(2017) Nortje, Griffin; Hill, Richard
Environmental Impact Assessment (EIA) is subject to challenges that undermine this process as an effective safeguard to biodiversity. Internationally, effective EIA is hindered by the following issues: a low priority assigned to the consideration of biodiversity and a limited capacity to carry out assessments; a lack of formalised procedures and inconsistent methodologies to address biodiversity within the EIA framework; and a lack of formal requirements for post-project monitoring of biodiversity aspects. Traditionally effectiveness studies in this regard have focused on evaluating the procedural aspects of EIA, and have focused less on the substantive outcomes of the post-authorisation phase of a proposed project. While South Africa has a considerable body of literature pertaining to the procedural aspects of EIA, there remain two substantial gaps in the literature. Firstly, there is an evident absence of effectiveness studies in South Africa that focus primarily on biodiversity-specific procedure. Secondly, almost no research has been conducted in South Africa which investigates the outcomes of mitigation measures, mandatory monitoring, reporting and compliance with biodiversity aspects of EIA. This research therefore aims to fill these gaps by investigating the quality of information generated in five EIAs in the Western Cape. It also examines the implementation success of mitigation measures aimed at managing unavoidable impacts in the post-authorisation phase of these projects. This research has adopted a case study methodological approach. Five EIAs were selected from a sample of 9. In no order of significance, the variables considered most important in the sampling protocol were: the presence of a biodiversity-related specialist report; availability of environmental assessment documentation; overall cases to represent at least two different local jurisdictions; and the uniqueness of adopted biodiversity-related mitigation measures. The primary method used to evaluate the quality of biodiversity-related information is a Key Performance Indicator analysis, whereby the performance of cases is measured against legal and best-practice reporting principles. The substantive outcomes of EIA have been investigated by means of site inspections and interviews with key stakeholders. This research has found that the five cases performed well with complying with best-practice EIA procedure, indicating a 53% full compliance, 29% partial compliance and 18% of best-practice principles were not complied with at all. This research has shown that direct impacts on biodiversity (such as the physical removal of indigenous vegetation) are adequately identified, and indirect impacts (typically those impacting off-site and on ecological processes) are poorly identified in EIA. Therefore, the information required to avoid impacts on biodiversity is available, but this research has found that it is underutilized in this regard. Notably, avoidance of impacts was undermined inadequate site and layout alternatives and poor decision making in terms of the regular authorisation of irreversible impacts on biodiversity. Conversely, only 18% of mitigation measures were fully complied with, 36% were partially complied with, and 45% of mitigation measures were not complied with. These results indicate a poor performance of EIA in the implementation stage of a project lifecycle. This research has concluded this is most likely due to a poor conversion of recommended mitigation measures into conditions of authorisation and a limited capacity of the competent authority to perform compliance monitoring.

Assessing the scope of effectiveness of stakeholder engagement in the development and implementation of the Environmental Management Plan for the Berg Water Project in the Western Cape Province, South Africa
(2016) Wachi, Bothwell; Hill, Richard
This research assesses the scope of stakeholder engagement and its effectiveness in the development and implementation of an Environmental Management Plan at project level. The theoretical basis of this research is the methodological premise that stakeholder engagement encourages quality environmental decisions and further promotes acceptable interventions for environmental management purposes towards sustainable development. A case study of the Berg Water Project is used to explore this premise through an evaluation of the scope and effectiveness of engagement of stakeholders in the formulation and implementation of the construction environmental management plan, to satisfy conditions of authorization. Focus is placed on the scope of stakeholders and their issues, and evaluation of the effectiveness of the engagement process in considering the issues during decision-making processes. The scope focuses on who was involved, the context in which they were involved, and the extent to which they were involved. An engagement framework is used to assess the effectiveness of the engagement process, including project institutions for stakeholder engagement, levels and methods of engagement applied, and their contribution to an effective Environmental Impact Assessment process with regard to its review areas of procedural, substantive and transactive effectiveness. The assessment seeks insights on how issues and concerns relating to activities of engagement were dealt with, and the extent to which issues raised through engagement contributed into project decisions. Evaluation of activities applies a stakeholder mapping and analysis concept found in stakeholder engagement literature in order to establish the suitability of level of engagement and methods of engagement. Logistical support for the engagement process is also assessed to establish how the support, or lack thereof, affected engagement effectiveness. An assessment is made of project documents within formation on stakeholders engaged during the environmental impact assessment process leading to the production of the construction environmental management plan, and information obtained from 45 interviewees from stakeholders who were engaged. The engagement process is accepted to be significantly inclusive as it covered a wide spectrum of stakeholders and gave them an opportunity to voice their concerns, and the outcomes indicated that the engagement process was adequate. Some notable weaknesses of the engagement process included failure to establish clear roles and responsibilities of the environmental monitoring committee-the entity which represented the interested and affected parties, failure to establish explicit engagement targets, and failure to identify potential trade-offs of environmental, economic and social expectations of stakeholders. By and large the effectiveness of engagement during the project was found to rest on commitment by project authorities to prioritize economic benefits for the local community, and the communication of relevant messages to stakeholders. Important lessons can be derived from this research towards improving the theory and practice of Environmental Impact Assessment. Firstly, explicit legal and funding requirements for stakeholder engagement are important prerequisites which should be imposed on project implementers regarding how they conduct the engagement process. Secondly, the presence, composition and functioning of a formal entity which represents the interests of identified interested and affected parties can broaden the range of issues that can inform project decisions. This entity should have clear roles which satisfy engagement objectives through scheduled activities which receive adequate logistical support. Thirdly, a communication approach should be devised to enable communication of relevant messages and ensure feedback mechanisms which inform and can improve the process. Lastly monitoring and auditing during the engagement process should have been done to assess satisfaction of substantive outcomes of engagement and environmental impact assessment beyond mere process compliance.

The benefits and burdens of living beside the Cederberg Wilderness Area
(2015) Wilson, John Martin Roy; Wynberg, Rachel Paula; February, Edmund Carl
A great deal is riding on conservation efforts of the twenty-first century. In an era of extinction rates one thousand times faster than ever before, protected areas have emerged as the most widely used tool available to conservationists to curb the loss of species (Child, 2004; Jepson & Ladle, 2010) . The number and extent of protected areas has increased dramatically over the past century, and their future growth is guaranteed by international and national policies (Brockington et al., 2008). The growing prevalence of protected areas on a global landscape has increased contact between communities and conservation, frequently with conflict arising as a consequence (Dowie, 2009). Increasing recognition of the impact of protected areas on local people has given rise to international consensus is that there is a dearth of knowledge surrounding these implications which needs to be addressed (Brockington et al., 2006; Igoe, 2006; West et al., 2006) . It is this gap that this study sets out to ameliorate. The overarching aim of this research was to investigate the benefits and burdens that local communities experience from living beside a protected area. Further, this study also investigated the causes of these benefits and burdens, how they were distributed between communities at a local scale, and how local perception of the protected area was influenced as a result of these experiences. The Cederberg Wilderness Area, which has a history of restricting resource use dating back to the 1890s, was selected as the protected area of interest. Of the nine neighbouring communities, consideration of the origin and similarity between communities resulted in Bosdorp and Heuningvlei adopted as representatives for the study area. Household surveys, key informant interviews, observations and documentary evidence were utilised to obtain data, and triangulation was used across methods to validate findings (Jick, 1979). Household surveys and key informant interviews were conducted over two separate field visits between March and April, 2014. In particular, the findings of this study were considered in terms of the ecosystem services framework, as the dominant theory suggested in literature surrounding the benefits and burdens that people obtain from protected areas (CBD, 1992; Government of South Africa, 2010; MA, 2005). This study found that a total of 14 beneficial uses of natural resources provided directly or indirectly by the Cederberg Wilderness Area were enjoyed by the case study communities at a local scale. The distribution of these beneficial resource uses between the two communities varied widely, with just six of the 14 uses enjoyed in both communities. In addition to income generated directly by the Cederberg Wilderness Area through conservation and indirectly through tourism, participants agreed that they received benefits in terms of aesthetics, recreation, education, and spirituality. Seven burdens were raised by participants, with all but one shared between communities. However, the less economically able of the two communities, Heuningvlei, did experience a greater number and distribution of burdens than Bosdorp, the village from which most employees of the CWA originate, and the community who receive considerably more average monthly household income. Although all participants in Bosdorp disagreed with the statement that life would be better without rules associated with the Cederberg Wilderness Area, a third of Heuningvlei participants agreed therewith. The most noteworthy observation in terms of incongruence with the literature was the extent to which both communities benefited from the protected area. The reason suggested for this observation was twofold. First, the long history of living with resource restrictions in Heuningvlei has allowed the community to adjust its norms, values and practices in order to maximise benefit from the Cederberg Wilderness Area. Second, the establishment of the Bosdorp community in close proximity to the operational offices for the Cederberg Wilderness Area has allowed residents to maximise employment and other opportunities from the protected area. In order to ascertain the causes of the observations mentioned above, the findings were framed in terms of the ecosystem services framework. This framework was subsequently found to be ineffective in identifying these causes. However, all observations left unexplained by the ecosystem services framework were explained by adopting Access Theory (Ribot & Peluso, 2003). This highlighted the important role the communities played in realising ecosystem services, and allowed for an evaluation of the appropriateness of the ecosystem services framework for incorporating social dimensions in conservation approaches. In conclusion, it was ascertained that many of the findings observed in this study were highly contextual and more often determined by the social systems in question as opposed to ecological systems. Therefore, conservation approaches that aim to achieve more resilient systems must take these social systems into consideration. It was also concluded that the current dearth of information about the social implications of protected areas limits the utility of debates surrounding the need to take these implications into consideration in conservation practices, and poses a potential fatal flaw to conservation practices based on false assumptions of social systems. This study ends by calling for further research on this matter in order to achieve management approaches that result in resilient biodiversity conservation.

Characteristics of fishers: a case study of Zeekoevlei, Cape Town
(2017) Gilliland, Toshca-Lee; Raemaekers, Serge
Fisheries are complex socio-ecological systems consisting of both human and ecological components. Managing fishery resources has almost always focused on ecological concerns without due consideration being given to the human dimensions. However, increasingly more scholars are recognising the need to integrate the human dimensions of fisheries management with the ecological concerns. Managing a fishery solely on the basis of ecological information will result in the management strategies being unsuccessful. Understanding the human dimensions is important as it provides insights into who participates in the fisheries industry, and what the behavioural patterns and motivations of the fishers are. This study focused on understanding the human dimensions of fishing at Zeekoevlei, focusing on who the fishers are and why they engage in fishing. It also addressed the source of conflicts at Zeekoevlei. The management of Zeekoevlei and fishing activities is also considered. A mixed methods approach, using a case study design, was adopted. The sample included fourteen fishers and six individuals involved on various levels of management of Zeekoevlei. Data-collection methods included the use of a structured questionnaire and semi-structured interviews. On the basis of this study, the demographics show that two types of fishers were found at Zeekoevlei – recreational and small scale. These fisher groups display contrasting socio-demographic profiles; however, a correlation between socio-demographics and motivations was observed. Recreational fishers appear to be white, educated males who are employed and engage in fishing for a sense of achievement, which is underpinned by the size of the fish. Small-scale fishers, on the other hand, are unemployed coloured males, with low levels of education and to this group of fishers the Zeekoevlei fishery system has an important function as it is used to diversify livelihoods. As with many fisheries, conflicts are prevalent at Zeekoevlei. These conflicts arise between fishers because Zeekoevlei has limited demarcated fishing spots and fishers display ownership over these spots; to exacerbate this situation, Zeekoevlei is located in an open reserve, which makes it easier for fishers to enter the reserve illegally. The management of the vlei appears to be based on recreational considerations with unclear measures to accommodate small-scale fisheries.

Contextualising the bycatch 'problem' in the Olifants Estuary Small-Scale Gillnet Fishery using an Ecosystem Approach to Fisheries
(2015) Rice, Wayne Stanley; Raemaekers, S; Sowman, Merle
Conventional fisheries management approaches have been shown, in many instances, to have been ineffective in dealing with complex conservation concerns such as bycatch. Greater considerations for broader-scale and holistic approaches, as proposed by the 'Ecosystem Approach to Fisheries' (EAF) and the 'balanced harvesting approach', are beginning to challenge some of the negative misconceptions around bycatch, especially in small-scale fisheries. The need for a more holistic approach to fisheries management, particularly in small-scale fisheries, in South Africa is highlighted by its commitment to an EAF and the recent Small-Scale Fisheries Policy, for which the Marine living Resource Act of 1998 provides the legal framework to implement. The case study of the Olifants estuary small-scale traditional gillnet fishing community, located on the west coast of South Africa, provides a particularly relevant example of a complex fishery requiring a holistic approach. Current regulations prohibit the harvesting or retention of any bycatch species. Fisheries management worldwide and in South Africa, generally view gillnet fisheries as destructive, due to the occurrence of bycatch and the fact that many of these bycatch species are considered overexploited, which has led to numerous attempts over the years to phase out the Olifants gillnet fishery. The purpose of this study was to, firstly, use an EAF framework to contextualise the issue of bycatch in the Olifants gillnet fishery, and secondly, to identify the relative contributions of all fisheriy sectors to the four key selected linefish species caught as bycatch by the fishery. An extensive review and analysis of available secondary data, as well as primary data collected for this study, have estimated, with acknowledged limitations, the magnitude of the exploitation by all known fisheries of these species. Key information from small-scale fisher interviews and community-monitoring data highlight the capture rate of key linefish species by this fishery. This is echoed by recent landings for 2012 indicating the relative contribution of the national beache seine and gillnet fishery to the overall catch of (Elf [Pomatomus saltatrix] - 26.94%; Silver Kob [Argyrosomus inodorus] - 0.88%; White Stumpnose [Rhabdosargus globiceps] - 1.05% - excluding the recreational sector). A significant finding of this study is the substantial levels of cross-sectorial exploitation of Silver Kob and White Stumpnose, and to a somewhat lesser extent Elf and White Steenbras.

The contribution of tourism to coastal livelihoods in Ponta do Ouro, Southern Mozambique
(2014) Come, Juliana ArsÃ©nio; Sowman, Merle
Tourism is increasingly seen as a panacea for the problems of rural areas, especially in developing countries. It is promoted by governments and international development organizations as a vehicle for achieving development, poverty reduction and economic growth. However, tourism has resulted in many unwanted economic, social, cultural and environmental consequences for local communities. Through a case study conducted in Ponta do Ouro, Southern Mozambique, this research sought to investigate the contribution of tourism to coastal livelihoods. The research assessed the extent to which tourism contributes to livelihoods of coastal communities of Ponta do Ouro, and their perception of benefits and negative impacts associated with tourism. Qualitative methods were used to collect data and included five focus group meetings, 46 key informant interviews, and participant observation. Findings of this study reveal that despite providing employment and other economic benefits to the livelihoods of the community of Ponta do Ouro, tourism also resulted in negative impacts on community livelihoods. These included overcrowding during high tourism seasons, loss of access to public land, rising prices of properties, goods and services, and an increase in crime, alcohol use and pollution. Therefore a pro-poor tourism approach is recommended as an attempt to ensure that benefits of tourism are better distributed and serve the needs of the local and broader community in terms of infrastructure development and improvement of social services and facilities.

The effects of urbanisation on non-timber forest product dependencies : a case study of three settlements in the Chobe district of northern Botswana
(2015) Joos-Vandewalle, Stephanie; Wynberg, Rachel
The aim of this study was to investigate the impacts of urbanisation on the use of, and access to, NTFPs in three settlements in the Chobe District of northern Botswana. Specific objectives were to determine the extent of NTFP use occurring in these areas; the purposes of use; the factors that influence use and access in the rural/urban context, particularly government rules and regulations; and implications for future NTFP use in this region. Research was conducted in three settlements: Kasane, Kazungula and Lesoma. Kasane is an urban town, Kazungula is less urbanised and Lesoma is a rural village. All areas are surrounded by state-owned Forest Reserves and the Chobe National Park. The study employed both qualitative and quantitative data collection methods including household interviews (30 in Kasane, 30 in Kazungula and 25 in Lesoma), four key informant interviews, two focus groups with youth and the collection of other grey literature relating to government harvest permits and market data. Households in all three areas used NTFPs despite the different rural and urban contexts in which they exist. Kasane and Kazungula showed a less diverse range of resource use, with fuelwood and wild foods the most commonly used resources in all three areas. These resources were used mainly for subsistence purposes. Harvest locations varied but were most commonly in and around the settlements themselves. Households in Kasane and Kazungula expressed the desire to use fewer resources in the future, mainly for conservation reasons, while those in Lesoma wished to use more. The government rules and regulations, particularly the DFRR permit system, were found to restrict resource access. Despite this, households in the more urban areas felt that the laws were necessary while those households in Lesoma thought that the laws conflicted with community livelihood needs. The majority of respondents believed conservation management to be a barrier to resource access as the presence of wild animals and anti- poaching units in the harvesting areas compromised safety. The general absence of resource commercialisation and market opportunities in the settlements, especially the urban towns of Kasane and Kazungula, were other commonly cited barriers to resource access. The perceived degradation of traditional practices due to modernity and urbanisation was evident for most households in all three areas but the actual loss of indigenous knowledge was most apparent in the urban areas. Wider implications for this case study are the application of the findings to further research into the impacts of urbanisation. This study can add to the literature around the implementation of improved urban development strategies, including the reliance on NTFPs and declines in cultural and environmental degradation. Recommendations provided in this study include further investigations into resource use; the application of resource co-management; improved market infrastructure and the implementation of ecotourism and local craft-making projects.

Exploring alternative values: the Cape Town talent exchange
(2014) Huddy, Belinda; Daya, Shari
The Cape Town Talent Exchange (CTTE) is a Community Exchange System operating locally in Cape Town, while allowing national and global exchanges to take place. Trading activity occurs between members of the community through an alternative currency, Talents. There are numerous incentives driving the participation of the community members. These include various political, social, economic, environmental and philosophical motivations. It is evident, however, that the members’ desires meet through the search for an alternative space where social interactions are experienced and social values are formed through economic activity. The construction of the CTTE as an alternative economy, that re¬‐introduces this social dimension into the economic sphere contributes to the movement away from the hegemonic, capitalist economy to one of heterogeneity. There are, however, tensions that lie in the overlapping nature of these systems, restricting the alterity and autonomy of the CTTE and emphasising the power and dominance of the mainstream economy.

Exploring the ecological and social benefits of the Khayelitsha Wetlands Park
(2017) Mathenjwa, Fezile; Anderson, Pippin; O'Farrell, Patrick
In a world confronted by rapid urbanization linked with dramatic population growth rates, there is a general consensus that quality urban green spaces are important components of urban landscapes. Urban green spaces are defined as open spaces in urban areas primarily covered with vegetation, which are available to users within the community. They have the ability to shape the image of cities and provide various important socioecological benefits, which can contribute to improving the quality of life within these urban communities. In Cape Town, the provision of readily accessible quality urban green spaces is often overridden by other conflicting demands, such as biodiversity conservation and infrastructure development demands. The literature suggests that Cape Town has ample available green spaces. However, the accessibility of this green space is linked to issues of poor management and maintenance, and as a result poor urban spaces are often associated with criminal activities, and are therefore unavailable to benefit urban communities. This is particularly evident in areas which have a low socioeconomic status. This study explores the ecosystem services offered by the Khayelitsha Wetlands Park in the Khayelitsha Township on the Cape Flats. A variety of methods were used to establish the condition of the Wetlands Park and assess the impacts of various uses (e.g. recreation, agriculture etc.) on the vegetation structure and water quality. Qualitative semi-structured interviews were also conducted to assess the local community's uses and perceptions of this green space. A Complex Adaptive Landscape (CAL) approach was adopted to derive the positive and negative social-ecological impacts of the Khayelitsha Wetlands Park. The vegetation structure assessment results showed a dominance of emergent and invasive vegetation, such as Typha capensis and Acacia cyclops, and indicates a high level of degradation and a lack of indigenous vegetation species. The water quality analysis reveals high concentrations of physiochemical and microbial pollutants, where a majority exceeded the Targeted Water Quality Ranges (TWQR) recommended by the Department of Water Affairs for livestock watering, irrigation and human use. Findings from the semi-structured interviews, revealed that a majority of users v visit the Park for multiple activities offered by the Park. These include relaxation, creating and maintaining social relations, sports and recreation and agricultural use. The CAL framework revealed negative and positive feedback mechanisms at play in this urban green space. The negative feedback effects are illustrated and confirmed by poor water quality and a predominantly alien infested vegetation structure. The poor ecological condition of the Wetland is linked to a number of anthropogenic influences, including the discharge of treated waste and untreated waste from both agricultural and urban waste sources, indicating the complexity of managing the Khayelitsha Wetlands Park. Since a number of users and management institutions are connected to the Khayelitsha Wetlands Park, their involvement in the management thereof is crucial for effectively solving the issues identified.

Food security and poverty reduction programmes: the experience of female headed households in a Cape Town community
(2016) Duncan, Sarah; Battersby, Jane
Living in impoverished urban areas, female headed households are most vulnerable to food insecurity. In order to reduce the risk and abate the experience of household food insecurity, civil society (NGO) and government have established numerous poverty reduction programmes and initiatives. However, in spite of ongoing efforts, the proportion of South African households experiencing food insecurity has not decreased but rather plateaued (SANHANES-1, Shisana et al, 2013). In order to address this plateau, the research has answered the question - how do food insecure female headed households experience the contributions of poverty reduction programmes in meeting their food security needs? The purpose of the study has been to add to relevant literature, with the aim of describing what food insecure households consider the contribution of poverty reduction programmes to be in meeting their food security needs. The research had four objectives - to describe (1) what food insecure households believe food in/security is, (2) how food insecure households experience food insecurity, (3) the characteristics of effective poverty reduction programmes from the perspective of food insecure households, and (4) the characteristics of ineffective poverty reduction programmes from the perspective of food insecure households. A descriptive qualitative methodology was used with data gathered through the methods of Photovoice with photo-elicitation interviews, semi-structured interviews, collage, observation field notes and a self-constructed questionnaire. The research participants, five female heads of households, were purposively sampled from a low-income Cape Town community. The research found that participant's food insecurity could not be separated from their lived experience of poverty. Making use of and influenced by Internal and External Drivers, participants were found to actively engage their living conditions with the use of social networks to be of particular importance. Participants experienced the contributions of programmes as 'half a help'. While programmes did help the participants and their households, that help served to only sustain rather than uplift them out of poverty and towards food security. If the plateau is to be addressed, then this study has argued that local programmes need to better engage their users and join with other multi-scale actors to form integrated poverty reduction programmes which offer more comprehensive, collaborative and dynamic approaches to the realization of household food security in South Africa.

The food-energy-water-land-biodiversity (FEWLB) nexus through the lens of the local level : an agricultural case study
(2015) Hulley, Sarah May; Ziervogel, Gina; New, Mark
There is a recognised need to turn the abstract concept of resilience thinking into practical action for resource management. This is often difficult as resource management is complex and multifaceted. Nexus thinking attempts to address this by promoting a framework that integrates and coordinates resource management across many different but interlinked resource pillars and sectors. This research focuses on the local level implementation of the food, energy, water, land and biodiversity (FEWLB) nexus framework, and assesses farmers' understanding and implementation of nexus thinking in relation to the support of the Bergrivier Municipality. Agriculturalists (farmers) have been described as significant custodians of natural resources, as they sit in a key position when it comes to implementing and practising sustainable development. There has been little research into the relationship between farmers and local municipalities, or into the role that local government can play in supporting holistic resource management through agriculture. While there are many different actors contributing towards resource management, this research focuses on the agricultural sector within the municipality. Qualitative research methods, including semi-structured interviews, participant observation and surveys, were used to undertake a case study of the agricultural sector within the Bergrivier Municipality. In a context where local government struggles to find its role in supporting socio-ecological resilience, the FEWLB nexus framework offers an opportunity to implement effective planning and policies that could enable more efficient resource use.

From drought to desalination: The case of Cape Town
(2021) Beerthuis, Sharda; Scheba, Suraya
The recent Cape Town drought and fear of a severe water crisis between 2015- 2018 was followed by a fast-tracked crisis management response. In line with a wider global trend, the City of Cape Town adopted a technology called ‘reverse osmosis desalination' into the water supply mix. This ‘water production' technology is alluring as it promises to be ‘drought- proof', preserving a constant flow of water in times of increased climatic uncertainty. Yet, the implementation of water technologies in Cape Town continues to be a highly debated topic. Cape Town suffers from a longstanding legacy of uneven racialized infrastructure development practices, resulting in unequal water access and consumption. In this context of unequal water security across social groups and increased climatic vulnerability, it is important to carefully consider the implications of new water technologies if the desired outcome is a more sustainable and equitable water future. Drawing on urban political ecology, this dissertation explores the process in which the instalment of three temporary desalination plants and planning for permanent desalination in Cape Town emerged. This, in order to carefully consider its consequences for equitable water security. By utilizing secondary official city documents, reports and news articles from several credible news platforms, supported by a number of personally conducted semistructured interviews and secondary sourced interviews with City employees, this thesis aims to understand how desalination is constituted as a crisis response. This exploration is organized around analyzing the relationships and dynamics between various actors, the events that signified the processual nature of the adoption and the emergent effects for water access across the City. The findings reveal that the promise that desalination holds as a technical solution to climatic uncertainty undermines the / contradictions that evolve alongside the instalments. While desalination was pushed by the municipality as a drought relief technology for all citizens, the results show that the emergence of this technology came with frictions, as it was contested, ecologically disturbed and critically questioned by multiple actors. As my findings demonstrate, desalination triggers the emergence of exclusive decision-making processes and financial constraints, especially for vulnerable citizens. This thesis thus argues that desalination implies to only secure water for some, while intensifying water insecurity for the already vulnerable. While the City strives towards a “shared water future”, the high focus on extending its water supply to meet growing demands lacks consideration of meeting existing demands, excluding the socio- political processes within current water decision making. This rather reinforces racialized- spatial and distributional inequities across a diverse range of social groups within the City.

From fork to farm: understanding Kitwe's food system through the fish lens
(2017) Siyanga-Tembo, Fridah; Battersby, Jane
Food production has been a constant feature of food security policies. This narrative has continued despite findings showing that food insecurity is structural, and more driven by issues of access than availability, particularly for low-income households in cities who live in a cash economy. While usually considered a rural issue, the urban poor with low and unreliable incomes also face food insecurity which manifests differently to that of their rural counterparts. Thus, this creates the need to understand how the urban poor get their food. Garneton, a low-income area in Kitwe, Zambia, was chosen as the case study area for understanding the food system that feeds the urban poor. Fish and the fish value chain were used as the lens with which to understand the food system. The primary aim of the study was to understand the flow of fish in the food system and how it gets to low-income households in Kitwe. A qualitative methodology using semi-structured in-depth interviews was used. A bottom up and systems approach which started by finding out what the low-income consumers ate, and following the fish value chain systematically up to the producers enabled the study to capture the actual food system that feeds the poor and uncovered the different issues affecting the food system. The study had three main findings. The first finding was that the low-income households bought their food from both formal and informal markets but were more highly dependent on the informal markets. The factors that drove their purchasing decisions included income, proximity and volumes of fish sold. Secondly, the study also found that informal traders bought their fish mainly through the informal markets although the imported fish was bought from the formal market. Thirdly, the study found that there were a number of factors that affected the food system. These included policy, economic and environmental factors. The pathways of fish were also found to change in accordance with the fish ban. The thesis argues that, there is greater need to have policy that addresses the needs of the urban poor. Food should also be looked at as a cross cutting issue with different food systems perceived as complementing each other to addressing the food needs, particularly of the urban poor. Finally, more attention must be paid to the informal market which plays a significant role in meeting the food security needs of the urban poor.

‘Grounding' ecosystem-based adaptation in the Western Cape Province
(2020) Maarstoel, Marte Nogva; Shackleton, Sheona
Ecosystem-based adaptation (EbA) advocates that well-functioning ecosystems are critical for building resilience and supporting society's adaptation to the adverse impacts of climate change. The National Department of Environmental Affairs, Fisheries and Forestry in South Africa has decided to mainstream EbA into its climate response actions, developing a strategy and set of guidelines to steer implementation. However, little work has been done to grasp different actors' perspectives and understandings of EbA, its implementation and how to link EbA to existing related projects and programmes that focus on natural resource management and ecological restoration. This research presents findings from a qualitative study in the Western Cape that sought to investigate what EbA means ‘on the ground' and how it can be actioned. The objectives for this research were to 1) unpack how government actors in the Western Cape relate to, understand and give meaning to EbA in their specific and existing work contexts and how they relate EbA to other concepts such as green infrastructure, restoration and various forms of natural resource management (NRM); 2) explore the concerns and challenges encountered and what support is needed to implement EbA within each actor's sector; and 3) interpret what the findings mean for future conceptualization, and promotion of EbA mainstreaming in the Western Cape. Semi-structured interviews with 19 government officials and participant observation at EbA related events in South Africa were the main methods used in the research. Findings suggest that despite some conceptual confusion related to EbA, EbA can be ‘grounded based on the three spheres EbA explicitly builds on; namely biodiversity and ecosystem conservation, climate change adaptation and socio-economic benefits. That said, the study also found that practitioners might struggle to successfully address climate change as one of the critical areas of EbA, due to the difficulties of integrating climate change science and projections into projects. In addition, three challenges were identified that relate to funding availability, silo mentality and the mismatch between short-term objectives and decision making in government, and the need for long-term thinking and planning. Increased climate change understanding together with effective demonstration and the use of applicable language that relates to what the different actors are already doing can help improve EbA uptake and mainstreaming, as well as address the challenges related to conceptual confusion, funding, silo mentality and short-term thinking.

Guarding dogs as a mitigation tool in human-wildlife conflict - case study: the Anatolian Shepherd Dog breeding project in Namaqua National Park
(2017) Binge, Elizabeth Naudé; Anderson, Pippin; Annecke, Wendy
This study conducted an evaluation of farmer and shepherd perceptions on Anatolian Shepherd dogs, used as livestock guarding dogs to mitigate farmer–wildlife conflict and meet conservation ends. The case study involved Anatolian Shepherd dogs bred at the Anatolian Shepherd Dog Breeding Project in the Namaqua National Park, and placed mostly on farms and at stock posts near the Namaqua National Park in the Northern Cape. The data were collected during structured and semi-structured interviews with livestock farmers and shepherds that received Anatolian Shepherd dogs from the Breeding Project. Anatolian Shepherd dogs were evaluated in terms of their contribution to reduce livestock losses and conservation of wildlife species. In terms of effectiveness in preventing or reducing livestock losses, 84% of the dogs eliminated or reduced livestock losses. Respondent satisfaction with the dogs was high, with 95% of respondents willing to recommend the Breeding Project and the use of Anatolian Shepherd dogs. Of the respondents, 95% perceived their dogs to be economically beneficial. Another 48% of respondents reported some form of behavioural problems at least once during the placement of the dogs. The most common reported problem was resting in the shade rather than accompanying the livestock. However, corrective training was effective in all cases where training was undertaken immediately. In terms of conservation, fewer respondents used lethal predator control methods in the years after placement of the dogs than before their placement. The overall perception regarding the use of lethal control methods (e.g. gin traps, shooting and poison) was that such control is cruel and that it is better to use non-lethal control methods only. However, a few respondents reported that lethal control measures were occasionally necessary to make a living when no other control measures were available, especially when the herd was relatively large. The effects of Anatolian Shepherd dogs on non-predator species in this study were minimal. The presence of the dogs therefore aided predator conservation and improved farmer tolerance of predators, especially by effectively reducing livestock losses.

Improving integrated wildfire management in the Fynbos Biome of South Africa using information on synoptic-scale atmospheric features that promote wildfires
(2015) Harrison, Dean Charles; Abiodun, Babatunde Joseph; Anderson, Pippin
Wildfire, an essential element for the Fynbos Biome of South Africa, can be a threat to property and human life if it is not well managed. Despite many studies on the dynamics and management of wildfire, the role of the atmosphere in inducing regional circulations that promote widespread wildfire is not well known. This dissertation studies the characteristics of wildfire in the Fynbos Biome, identifies synoptic-scale atmospheric features that produce favourable conditions for the wildfire, and examines possibility of using the features as indicators for wildfire occurrence. Ten years (2003 - 2012) of fire data from the MODIS "active-fires" datasets were analysed over the study domain. Daily Fire Danger Index (FDI) was calculated over Southern Africa for this period using maximum temperature (Tmax), minimum relative humidity (RHmin), and maximum wind speed (Wmax) data from the Climate Forecasting System Reanalysis datasets (CFSR) at a 0.5°x0.5° horizontal resolution. The Self Organising Maps (SOMs) technique was used to classify the FDI (anomaly) patterns on the fire days, and the atmospheric dynamics associated with each pattern were studied.

Integrated reporting : inspiring companies to integrate sustainability into their business strategy and practice?
(2015) Goldman, Jonny; Hill, Richard; Hamann, Ralph
This research focuses on the potential convergence between the 'form' of corporate sustainability (CS), represented by selected South African companies' integrated reports (IRs), and the underlying 'substance' of CS, being the integration of sustainability into companies' strategy and operations. The research also explores the extent to which organisational culture and management systems underpin and operationalise integrated reporting (IR) and CS. The research is approached from two perspectives: firstly, the research investigates the strategies and implementation of IR and CS independent of one another, and aims to reveal contemporary IR and CS practice and challenges; secondly, the research focuses on the potential relationship between IR and CS by seeking to identify any synergies between the IR and CS, and aims to provide insight into whether IR can further a company's CS ambitions, and if so, how this occurs. The research follows a case study research methodology, which is considered suitable for research into new fields given its predisposition to theory building. The cases were selected from those included in Ernst & Young's Excellence in Integrated Reporting Awards for 2012 (EY 2012 survey), which reviewed and rated the IRs of the top 100 companies on the Johannesburg Stock Exchange (JSE). The sample includes a total of six companies selected from the above-mentioned top 100 companies, being two companies from each of three JSE super-sectors. Of the two companies in each super-sector, one company was recognised by the EY 2012 survey as having produced a superior integrated report and the other company had not achieved such recognition. A detailed review of each company's two most recent IRs and sustainability report was undertaken to inform and facilitate meaningful and insightful interviews with appropriate personnel from various departments within each company, including corporate affairs and communication; environmental; strategy and business development; finance; sustainability; human resources; governance, risk and compliance; and corporate social investment. Primarily open-ended questions were posed to allow for the collection of qualitative, company- specific information on companies' IR and CS strategies and implementation. The broad-based adoption of IR in South Africa, in response to the JSE regulation requiring listed companies to produce an integrated report or explain why they have not, has provided a sound platform for revealing the early stages of IR practice. Although CS is not a new corporate discipline, it remains a somewhat contested corporate practice, evident from the broad spectrum of companies' approaches to CS: these range from a basic compliance standpoint to more holistic synergistic strategies aimed at integrating CS into all parts of the business. Given the differing approaches to, and appetites for, IR and CS amongst the researched companies, the findings identify certain dominant themes of contemporary practice, and reveal opportunities for expanding and improving IR and CS. Indications are that management systems play an important role in the implementation of IR and CS strategies. IR, a relatively stand-alone corporate function, shows limited dependence on organisational culture, which is a key determinant for CS given its extensive reach within companies and reliance on employee buy-in for engaging with CS. The findings also uncover other key insights into the multi-faceted relationships between IR, CS, organisational culture and management systems. Finally, although there are some synergies between IR and CS, these represent a more subtle, constrained IR and CS relationship. To conclude, although the findings recognise that IR can stimulate a focus on CS in companies that have yet to seriously engage with CS, succeeding in IR does not appear for the most part to provide an indication of proficient CS capability, reflecting a decoupling of IR practice and success from that for CS.

Integrating sustainability thinking and practices into surfing events: case studies in Hawaii and Jeffreys Bay
(2018) Nguyen, Tina; Sowman, Merle
Sustainable surfing events are a recent phenomenon and there is little to no academic literature reflecting this development. Sustainable event management (SEM) is the integration of sustainability principles and practices into event production to produce an event that goes beyond economic longevity and fulfils important social, cultural, and environmental roles that people value. This research explores the current practices and issues surrounding the implementation of SEM into surfing events held in Hawaii, USA and in Jeffreys Bay, South Africa. The thesis follows a qualitative case study approach using semi-structured interviews, participant observation and documentary evidence. Findings demonstrated that the key obstacles to implementing sustainable event management principles and practices include limited access to capital, lack of government support, resistance to change, the absence of a common vision, and a lack of education and awareness. This study revealed the importance of context in a hosting community's journey towards sustainable event production. Overcoming these obstacles requires engagement of the private sector, influence of local champions, involvement of NGOs, trusting relationships between local and external event stakeholders, access to technology and resources, and the strategic use of media to promote sustainability awareness to all event stakeholders. Based on these findings, recommendations for improving the sustainability performance of surfing events include the development of a formal policy, education and training for event staff, a media campaign focused on sustainability issues, and in-depth engagement with the local hosting community. How the enabling or inhibiting factors play out on the ground depends on the variety of factors previously highlighted. In practice, there are linkages across SEM practices and many work in concert to enhance the overall sustainability performance. Theoretically, the implications of this research lie in its contribution to a growing body of knowledge pertaining to the surfing industry's transition towards more sustainable business operations. Practically, this information can be used to inform policy, set goals, carefully examine alternatives, establish effective factors to enable SEM, and encourage sustainable decision-making and actions. Other surfing communities can learn from the experiences of the event stakeholders in Hawaii and Jeffreys Bay to improve their efforts of hosting a sustainable surfing event. Overall, this knowledge can promote a more balanced dissemination of sustainability thinking and practices within the global surfing events sector.
