Conservation is increasingly understood to require collective action, particularly in the context of community based conservation. This thesis is premised on the proposition that understanding the dynamic nature of the relationship between collective identity and collective action is fundamental to management of common pool resources such as are created through establishment of community conservancies in Namibia. I used collective identity and resilience theories to develop a framework for exploring change in collective action in the Doro !Nawas conservancy in Namibia. The framework is based on the assumption that change in collective action is dependent upon the temporal changes in two attributes of collective identity; identification and affective commitment. It is suggested that the framework also yields insight into how these may be applied in adaptive management. The research is informed by an interpretive paradigm accepting that collective identity and collective action are social constructs and that personal meanings could be revealed through in-depth interviews and documentary analysis. Computer aided software (Nvivo), manual analysis and a mix of inductive and deductive analysis yielded excerpts, codes and themes that were used to interpret change in the two attributes. The framework I proposed to understand how identification and affective commitment influence collective action was helpful as a general model but it tends to convey a degree of cohesion and homogeneity that does not reflect the real situation, particularly during the ‘collapse’ phase when members of the collective respond to disturbances. My results show that collectives, including organisations, should be understood as collectives of individuals and groups of individuals who express differing levels of identification and affective commitment. Narratives can be used to track change in identification and affective commitment in collectives. Thus, the identification and affective commitment of members is reflected in the language they use to express feelings, thoughts and experiences toward the collective and behaviours that are supportive or destructive to collective identity. A need for incorporating collective identity into adaptive management is identified. I suggest that incorporating collective identity in strategic adaptive management would make those who engage with the process mindful of the collective identity, and therefore more inclined to manage collective identity in order to achieve the collective action required for successful common pool resources management. I use the findings of my research to identify four issues for further research in community based collectives: firstly, research that focuses on the how to design institutional arrangements for conservancies and similar organisations that are more accessible and responsive to the collective; secondly, research on understanding the role and influence benefit sharing can have in sustaining a collective identity that is supportive of conservancies and how it would contribute to making these systems more resilient; thirdly, research to determine how strategic adaptive management can be restructured and implemented in conservancies and protected areas so that it helps to sustain a collective identity and the collective actions that are required to secure them for future generations; finally, whether the long term intentions of community based conservation might be better served if the instruments of governance and the procedures for their application were engineered to make these social ecological systems more robust and if so, how this might be achieved. / Thesis (Ph.D.)-University of KwaZulu-Natal, Pietermaritzburg, 2012.

Thaumastocoris peregrinus (T. peregrinus) is a sap-sucking insect that feeds on Eucalyptus leaves. It poses a major threat to the forest sector by reducing the photosynthetic ability of the tree, resulting in stunted growth and even death of severely infested trees. The foliage of the tree infested with T. peregrinus turns into a deep red-brown colour starting at the northern side of the canopy but progressively spreads to the entire canopy. The monitoring of T. peregrinus and the effect it has on plantation health is essential to ensure productivity and future sustainability of forest yields. Insitu hyperspectral remote sensing combined with greater availability and lower cost of new generation multispectral satellite data, provides opportunities to detect and map T. peregrinus damage in plantation forests. This research advocates the development of remote sensing techniques to accurately detect and map T. peregrinus damage, an assessment that is critically needed to monitor plantation health in South Africa. The study first provides an overview of how improvements in multispectral and hyperspectral technology can be used to detect and map T. peregrinus damage, based on the previous work done on the remote sensing of forest pests. Secondly, the utility of field hyperspectral remote sensing in predicting T. peregrinus damage was tested. High resolution field spectral data that was resampled to the Hyperion sensor successfully predicted T. peregrinus damage with high accuracies using narrowband normalized indices and vegetation indices. Field spectroscopy was further tested in predicting water stress induced by T. peregrinus infestation, in order to identify early physiological stages of damage. A neural network algorithm successfully predicted plant water content and equivalent water thickness in T. peregrinus infested plantations. The result is promising for forest health monitoring programmes in detecting previsual physiological stages of damage. The analysis was then upscaled from field hyperspectral sensing to spaceborne sensing using the new generation WorldView-2 multispectral sensor, which contains key vegetation wavelengths. Partial least squares regression models were developed from the WorldView-2 bands and indices and significant predictors were identified by variable importance scores. The red edge and near-infrared bands of the WorldView-2 sensor, together with pigment specific indices predicted and mapped T. peregrinus damage with high accuracies. The study further combined environmental variables and vegetation indices calculated from the WorldView-2 imagery to improve the prediction and mapping of T. peregrinus damage using a multiple stepwise regression approach. The regression model selected the near infrared band 8 of the WorldView-2 sensor and the temperature dataset to predict and map T. peregrinus damage with high accuracies on an independent test dataset. This research contributes to the field of knowledge by developing innovative remote sensing techniques that can accurately detect and map T. peregrinus damage using the new generation WorldView-2 sensor. The result is significant for forest health monitoring and highlights the importance of improved sensors which contain key vegetation wavelengths for plantation health assessments. / Thesis (Ph.D.)-University of KwaZulu-Natal, Pietermaritzburg, 2012.

For decades, South Africa has been heavily infested by invasive alien plants. As a result there is concern over the increasing rate at which the alien plants are replacing indigenous vegetation. Another concern regarding the invasive alien plants is the indirect stress they pose on the environment due to their excessive water consumption. As a result of this, government of South Africa, through the Conservation of Agricultural Resources Acts (43 of 1983) and other environmental legislation, mandates and encourages the removal of invasive alien plants from the landscapes of South Africa. The need for removal of these invasive alien plants led to the formation of the Working for Water Programme (WfW), which is based on a novel approach to environmental management. It contends that the invasion of ecosystems by invasive alien plants could have detrimental effects on water yields from catchment areas, and that employing people to deal with the problem could both protect this vital resource and provide employment and upliftment in poor rural communities. It has been suggested that the supply of information to the public about invasive alien plants is generally poor, to the extent that many people are the causal agents of these plants entering their communities (McNeely 1999). If this lack of awareness is the case, then understanding the drivers of local knowledge which will feed into public awareness is essential to change public perceptions and values surrounding invasive alien plants. It is important to understand local knowledge in order to determine gaps in information transfer and enable them to make decisions that are grounded in local cultural interpretations of place and their environment (Ebohon et al 2000). It is also important to ii understand what the local communities know and what they need to know about these invasive alien plants. This study is premised on developing an understanding of local knowledge and perceptions about invasive alien plants. The assumption is that those involved in the programme would display positive values towards the environment. It is also assumed that those involved in the programme have developed their local/traditional knowledge of invasive alien plants through the educational component of WfW programme. A case study approach of Upper Illovu Working for Water project was adopted. The research was carried out by means of questionnaire interviews. The respondents were drawn from Indaleni community in Richmond, KwaZulu-Natal. Thirty respondents were interviewed and this was inclusive of the field workers, contractors, project manager and people who were not involved in the project but from the same community. Those not involved in the project were used as a control group. Five objectives were utilized to investigate the aim of this study. They were to: a) Determine the respondents’ relationship to, and perceptions of the Upper Illovu WfW project b) Establish the respondents’ understanding and perceptions about the levels of invasive alien plants in the area c) Determine the respondents’ knowledge and perceptions pertaining to prevention of the spread of invasive alien plants iii d) Establish the respondents’ competencies in controlling and managing invasive alien plants and e) Establish the respondents’ perceptions about the project’s ability to deliver on its objectives. The results of this study indicate that most of the respondents were aware of the Upper IIlovu WfW project and its ecological and social upliftment objectives. The pattern of the responses was such that those that did not participate in the project (control group) were for the most part not sure about their responses. Although those who participated in the project displayed better knowledge of issues concerning invasive alien plants, there were many occasions when they failed to provide some responses without being prompted – given clues or examples. To conclude, there was, therefore, a significant knowledge gap about invasive alien plants and information pertaining to them between the two groups. The implications are that those involved with the project must have received some form of information through public awareness about invasive alien plants. That is their traditional knowledge about these invasive plants has been developed by the education from the programme, WfW. But most importantly, the programme remains a key for economic reasons from the perspective of the participants. The need for constant improvement and development of local knowledge regarding these invasive alien plants is important in dealing with their spread and management of their effects on the environment. / Thesis (M.Env.Dev.)-University of KwaZulu-Natal, Pietermaritzburg, 2010.

Since the 1970's, the increasing scale and complexity of development schemes has led to mounting public concerns about their environmental impacts. Environmental assessment and management developed out of a recognised need to protect the biophysical environment from overuse and degradation . Evidence suggests that the issues continue to become more complex and we need to equip ourselves to deal with them. The complexity of issues we face today demands a holistic and integrated management approach. This thesis highlights the weakness in the application of environmental impact assessment (EIA) to deal with current issues . The conceptualization of EIA within the ecological modernisation discourse has limited the use of the tool to adequately consider issues outside the biophysical environment. On the African continent, social issues such as HIV/AIDS are becoming more dominant than biophysical impacts. EIA must thus be re-framed to address concerns regarding the HIV/AIDS impact of development schemes. An alternative discourse of social justice is put forward as an approach that will take EIA closer to achieving sustainable development. The hypotheses put forward in the thesis were investigated through the use of both primary and secondary data sources. Extensive interviews and case studies formed the bulk of the data generated through the study. The results of the investigation showed that there are varying views on the purpose of EIA, that social issues continue to be underplayed in the process and that HIV/AIDS is considered a valid impact to be assessed in EIA. It must be noted that although HIV/AIDS is recognized as a common impact of development projects, particularly in Africa , the approach to dealing with the issue has been very different across EIAs and the issue is dealt with in an ad hoc manner. In order to expand the applicability of environmental assessment in Africa , a framework has been developed to integrate HIV/AIDS into the EIA process. The premise behind the framework is that HIV/AIDS can impact on the viability of a development scheme and conversely, development schemes can increase the transmission of HIV. The framework considers the social, economic and cultural drivers that create living and working environments, which promote the transmission of HIV. By applying the appropriate tools throughout the EIA process, one can identify potential impacts. Mitigation and management interventions can then be built into an HIV/AIDS component of the environmental management plan. This approach will allow environmental assessment practitioners; decision-makers and developers to better understand the critical issue of HIV/AIDS and ultimately contribute to managing the pandemic and further sustainable development in Africa. / Thesis (M.Sc.)-University of KwaZulu-Natal, 2005.

A social survey of the communities living adjacent to the Pongolo river floodplain was carried out, in order to understand the perceptions of the impact of artificial flood releases on the general use of natural resources of Pongolo floodplain in terms of: general resource use, stream flow, water quality and subsistence agriculture. The results show that floodplain communities perceive that the present artificial flood releases which are intended to maintain the environmental requirements of the floodplain are not meeting their needs nor the needs of the environment. Key perceptions on environmental impacts identified are: (i) reduction in water required to maintain floodplain resources, (ii) deterioration in water quality and (iii) decrease in available floodplain land and natural resources. / Thesis (M.Env.Dev.) - University of KwaZulu-Natal, Pietermaritzburg, 2007.

Many believe that small and medium natural resource-based enterprises (NRBEs) provide a vision to reduce poverty in the Third World’s rural communities and households. As a result, new rural enterprises should be created and existing ones reinforced within a framework of sustainable livelihoods that target all appropriate members in the communities. This study investigates the impact of the natural resource based enterprises income on the rural livelihoods in the households using a rural natural-based craft enterprise (using reeds, Cyperus spp, as raw material), as a case study, Ikhowe Craft Enterprise, situated in small town called Eshowe in northern KwaZulu-Natal, South Africa.. In designing this study, a combination of both qualitative and quantitative research methods was employed. This was influenced by the aim and the type of data required for the study. The said methods were (a) semi-structured interviews for producers (a questionnaire had a pre-determined mix set of both open-ended and closed-ended questions); (b) interviews for management were conducted with a purely qualitative questionnaire which consisted of only structured and open-ended questions; (c) field observations, and (d) a review of secondary materials (administrative records). Apart from how derived income impacts on the participants, data required also included performance of the enterprise, access to markets, support available, and livelihood analysis of the participants households which included issues such as households’ economies and exploring extent of, and reasons for diversification, and challenges both the enterprise and participants’ households face daily in relation to making a living. The results show that there was a significant increase in business annual turnover and producers’ earnings between 2003 and 2005. In 2003, about 50% of the producers earned less than R1000 per year, while in 2005 only 3% earned less than R1000 per year. Despite the total annual increase of earnings and the significant contribution of craft income to producers’ households’ incomes, individual earnings varied considerably amongst the producers and as a result the economic impact was also variable. Other than craft, strategies such as government grants enhanced livelihood diversification in the case study. However, lack of understanding of basic business principles and skills amongst both the crafters and management posed threats to the sustainability of the enterprise. The income derived from the NRBE activity, especially since it is based on natural resources with low economic value (reeds) was found to have both diversifying and supplementing effects on different producers’ other strategies. Although, the enterprise is achieving growth, there is a concern and a need to measure the future sustainability of the enterprise. In addition there is a need to improve the producers’ basic business skills and business management competency / Thesis (M.Env.Dev.)-University of KwaZulu-Natal, Pietermaritzburg, 2008.

Numerous land reform policy instruments and initiatives that have been implemented since the beginning of the 1990's are mediating the on-going battle between formal land tenure systems and informal customary land tenure arrangements. The policy instruments and initiatives seek to establish a delicate balance that will suit the diverse needs of the population of South Africa with respect to land. The enormity of this task is evident when one is faced with the reality that South Africa has the third highest Gini index (a measure of inequality in the distribution of land) in the world. The Eastern Cape Province is one of the poorest provinces in South Africa, and has been affected most by the land segregationist and homeland policies of previous colonial and apartheid regimes. It is not only the unequal distribution of land, but also the vast array of insecure tenure arrangements that have had a detrimental effect on the development and empowerment of communities resident on communal land. This research analyses one initiative that intends to strengthen the security of tenure of existing occupants of communal land in the remote rural areas of the Eastern Cape Province. The research critically appraises the Administrative Area Boundary Project of the Department of Land Affairs (that aims to identify and complete the formal surveys of all administrative area boundaries in the Eastern Cape) in the light of the intentions of the Communal Land Rights Act (No. 11 of 2004) (CLaRA), and highlights the challenges in formalising the informal tenure arrangements of occupants of communal land. The different aspects of the Administrative Area Boundary Project (both office work and field work) were evaluated in order to determine not only its feasibility, but also its impact as an effective instrument of land reform in its endeavour to provide secure land rights to millions of South Africans residing in former homeland areas. To this end, both desktop and case study methodologies were used in order to collect and analyse the research data. / Thesis (M.Sc.)-University of KwaZulu-Natal, Pietermaritzburg, 2006.

Sound management of information and data is an essential cornerstone for efficient and effective decision making. Structured, up to date and easily retrievable data from several heterogeneous sources is often required to effectively manage, monitor and predict resource quantities particularly for depleting resources such as fish. The documentation and management of fisheries data in most developing countries however poses great challenges. The main aim of this study therefore is to design an information system (IS) for Artisanal Fisheries management. The developed IS is supported by a database. Secondary data, from the provincial offices of Moma and Angoche in Mozambique, is used to test and populate the prototype database. The manner in which the database is developed demonstrates how in practice a database can be created as part of an information system. However, due to time restrictions, a complete database for the AF system could not be developed. To accomplish the objectives of the study, a model of the Artisanal Fisheries (AF) system was developed first. Based on standard system development approaches, the key components of the AF system that include; processes, data flows and data stores, were identified. The developed conceptual system was then used to identify critical data stores for the AF system and data models were subsequently developed. A prototype database to support the AF system was then implemented in MS Access. The motivation for this study is as a result of two observations made on information management which are a challenge in artisanal fisheries management in Moma-Angoche. These observations are; (i) the current information system lacks a structured approach and a database to document and archive data/information on the artisanal fisheries subsector; and, (ii) the high proportion of the data/information collected from different sources is not well processed, analyzed and is not user-friendly as yet. The Moma-Angoche Provincial Fisheries office was chosen because it is strategically suitable for research. This has been demonstrated by the amount of socio-economic artisanal fishing census data already collected and by the research on stock marine resources already carried out. As a result, the study area has become a pilot zone of integrated fisheries development projects. During the life cycle of the various projects, and even after their termination, the area remained an important zone where subsequent studies (for example baseline studies) were carried out. Furthermore, the existence of subsequent data available from those studies allows a good opportunity for data comparisons to be made. / Thesis (M.Env.Dev.) - University of KwaZulu-Natal, Pietermaritzburg, 2007.

The aim of this study was to engage small-scale timber growers in the development of national principles, criteria, indicators and standards (PCI&S) for sustainable forest management (SFM) in South Africa (SA). To ensure effective participation of small-scale timber growers in the development PCI&S, an overview of sustainable and small-scale forestry was explored. Furthermore, because of the importance of globalisation on the SFM concept, its conceptual framework and small-scale forestry development in relation to SFM were investigated. Participatory rural appraisal (PRA) methods, and PCI&S evaluation and development processes were used to engage small-scale timber growers by identifying and integrating their perceptions into the process of SFM standards development. These small-scale timber growers' perceptions focused on social, economic, environment and policy issues. The stUdy indicates that the views of small-scale timber growers regarding SFM do not vary significantly from those held globally. However, they demonstrate that local conditions determined issues of relevance and importance to this specific group. The results further support the view that there is value in combining both top-down and bottom-up approaches in developing an appropriate set of PCI&S. This is critical because the perceptions of small-scale timber growers for SFM are scale sensitive. Finally, the results supported the view that there is a need to give attention to and strengthen socio-economic issues versus those of the physical environment to improve inequalities of the past, and influence future decisions. / Thesis (M.Sc.)-University of KwaZulu-Natal, Pietermaritzburg, 2005.

Alleycropping is an agroforestry technology of planting crops between rows of trees, preferable legumes to promote an interaction among them with positive benefits in terms of improving soil fertility and hence good crop yields. The technology has been tested with a variety of trees/shrubs species in association with crops (alleycropping) or with grasses (alleygrazing), sometimes with encouraging results and sometimes not, in a wide range of environmental conditions around the world. Research in alleycropping started in late 1970s and sinc~ then many publications have been released. However, little or nothing has been reported about this technology using black wattle and the fever tree, two nitrogen-fixing trees common in South Africa and reported as fast-growing species which produce a considerable amount of biomass within a short period of time. Due to that fact, a two-year trial was established in 2003 at the Ukulinga research farm, Pietermaritzburg, South Africa to evaluate the potential of the two tree species under alleycropping with maize and cowpeas as joint intercrops, under alleycropping with pumpkin, and under alleygrazing with Eragrostis curvula and with Panicum maximum. The trial assessed the crop yields and the biomass production from all the components, and their fodder digestibility using Neutral Detergent Fibre (NDF) and Acid Detergent Fibre (ADF) determinations. Additionally the changes in tree grovlth vaa."'i.ables (difu~eter, total height, total \lollhl1e and biomass) were mortitored to produce regression equations to predict those variables, one from another, using regression analysis. The diameter was taken at ground level (dgl) and at the height of 1.3 m, normally called diameter at breast height (dbh). The results showed that tree growth and biomass production were better in black wattle alleycropping than in association with the fever tree. The average dgl of black wattle after 12 months was 48mm and the average dbh was 36mlll. Over the same period the total tree height was about 406cm. A tree pruning was done to one-year old black wattle in the whole trial and the prunings produced about 5.6t/ha of fresh foliage biomass in the association with maize and cowpea and 4.5t/ha in the association with pumpkin. In alleygrazing the growth variables were similar to those obtained in alleycropping but the biomass production was considerably different. The prunings produced about 7.66t/ha of fresh foliage biomass. The dry matter biomass from the prunings was 1.96t/ha, 1.58t/ha and 2.68t/ha in the association with maize and cowpeas, pumpkin and E. curvula respectively. The dry matter was obtained from 4days- oven-dried samples and it was 35% of the fresh foliage biomass and 60% of the fresh woody biomass. The fever tree did not grow significantly during the study period and due to that fact, the species was discarded from the study. Similarly, because after several endeavours using different seed lots, P. maximum had germinated very unevenly, and this grass was excluded from the experimentation. Values ofNDF and ADF less than 35% are considered good, between 35% and 60% fair and poor if greater than 50%. Using is classification the NDF and ADF values from this study were good in pumpkin (30.5% and 29.9%) and cowpeas (36.5% and 46.9%) biomass, fair in E. curvula (41.9% and 39.9%) and maize stover (53.6% and 42.1%) and poor in black wattle (76.58% and 68.1%) foliage. If black wattle is to be used as fodder, it must be mixed with highly digestible fodder like P. maximum, Digitaria sp., and other legume plants, to increase animal intake and to avoid any risk of it becoming an animal hazard due to tannin effects. The regression equations produced linear relationships between dgl and age, and biomass and dbh. The other interactions were not linear. The best equations were obtained in the interaction between dgl and age (dgl= 4.8*Age -7.03; R2 =0.86; SE= 6.6), dgl and height (h= -0.03dg12 + 10.5dgl - 21.25; R2= 0.96, SE= 42.9, h= height), biomass and dbh (lny = 2.409*lndbh; R2=0.99, SE=O.O, Y= tree foliage biomass). During the study, monkeys, cattle, birds and bushbucks posed a threat to the success of the study due to damage they caused to the crops. It was possible to keep the damage below the critical levels, although at high cost. / Thesis (M.Env.Dev.)-University of KwaZulu-Natal, Pietermaritzburg, 2006.
