In recent years, one of the most significant pieces of environmental legislation in New Zealand has been the Resource Management Act (New Zealand Government 1991) that has empowered local government agencies to manage the use of natural resources in their regions. Three Government Departments have been responsible for developing policies directly relating to the use of natural resources in New Zealand. The Department of Conservation has been mainly concerned with the management of natural resources on public land. The Ministry for the Environment has particularly addressed environmental policy issues of national significance. The Ministry of Agriculture and Forestry has worked with New Zealand's agricultural, horticultural and forestry industries to encourage sustainable resource use and development for the benefit of all New Zealanders. In general, local and central government agencies carrying out policy analyses have drawn upon highly goal driven theories such as Rational Choice or Incremental Policy Theories or alternatively they have applied more loosely framed theories such as Systems Policy Thinking or Garbage Can Theory. Policy formulation and instrument selection may have been based upon instrumentalist, proceduralist, contingentist or constitutivist selection criteria, depending upon the assumed influence of peoples' behavioural and social contexts in addition to the technical characteristics of the tools themselves. However, there has been a limited range of policy theories to guide the integration of policy analysis, and formulation and operational planning into a management strategy for effective policy delivery. Such theories would have assisted policy agencies to identify the human and social behaviours most closely related to policy issues and to better match policies to differences in the political and social context of each of the issues that they were dealing with. In academic articles a number of behaviour models from social psychology have been used to explain and predict human behaviour. One of those, the Theory of Reasoned Action (TRA) has a long history of use in research and application. It has been adapted to suit the needs of policy makers in human health, marketing, and education. Applications of the TRA have been reported to have achieved coefficients of determination for behaviour of on average, 53% in one study and 71% in another. Some of the modified models based upon the Theory such as the Theory of Planned Behaviour, have in themselves been able to make additional contributions to peoples' understanding of how to explain and predict human behaviour in more complex situations. In this report, unless otherwise stated, references to the TRA are inclusive of all associated models, such as the Theory of Planned Behaviour. This thesis has examined the application of the Theory of Reasoned Action in the formulation of environmental policy. Five research questions were considered. 1. Could a human behaviour model based upon the Theory of Reasoned Action be developed sufficiently for environmental policy makers to explain landowner behaviour associated with managing indigenous vegetation? 2. How well could the social psychology model of human behaviour based upon the TRA have predicted public responses to a policy programme? 3. How well could the social psychology model of human behaviour based upon the TRA have distinguished between the policy-intervention needs of different stakeholder groups? 4. How much have peoples' values, attitudes and beliefs affected their behaviour? 5. What would be the immediate antecedents to peoples' behaviour and how have they led to behaviour change? This has been a quantitative study to develop and test models of human behaviour specific to the preservation of indigenous vegetation. Three data sets were compared from surveys of peoples' bush protection behaviour, the establishment of indigenous woodlots and the protection and planting of riparian areas with indigenous vegetation. The results from the analyses have shown that accounting for peoples' intentions could have been used to improve the estimates of peoples' use of policy-desired practices. The coefficients of determination in multivariate equations to predict peoples' natural resource behaviour based upon non-specific (external) variables, varied between 3 - 10%. By including intentions in the models, the level of explanation increased to 10 - 17%. The results may have been lower than expected from other examples in the literature due to poorly specified measures of behaviour relative to the measures used for intentions. When it came to estimating intentions (rather than the actual behaviours), the TRA variables in regression equations achieved coefficients of determination of 55 - 75% and these provided a measure of how well the underlying values, attitudes and beliefs could have given policy makers an understanding of peoples' behaviour. Comparing the beliefs of people with high and low intentions to perform the behaviours, clear differences have been identified that could have been the basis of policy strategies for behaviour change. After analysing and considering these examples, this thesis has argued that the TRA could be used in the future to provide policy agencies with an increased level of understanding of human behaviour and so enable them to formulate policy interventions for achieving predictable levels of behaviour change.

Fuelwood is a basic need for rural households in Malawi. However, deforestation has reduced the quantity of forest products such as fuelwood available to households. This has negatively affected rural Malawian quality of life, especially for women who are forced to walk long distances to collect fuelwood, prepare foods with short cooking times, or reduce the number of meals. The Malawi government has encouraged the establishment of household owned woodlots, as a part of reforestation programs, to address the supply side of the forest product scarcity. However, fuelwood supply and use is also a gender-based issue; men plant trees and make decisions over harvesting, while women gather and use fuelwood. Within the household, woodlot products also have multiple and competing uses between men and women. It is critical to examine how gender dynamics affect women's fuelwood procurement and use from the woodlot. This study investigated how gender of the household head and women's access to woodlots affects fuelwood shortage, controlling for number of trees, household size, and use of other fuels. Fifty-one female and sixty-three male-headed households with household owned woodlots were interviewed, using questionnaire and focus group interviews. Results show that one-third of both household types reported experiencing fuelwood shortages in the past year. Logistic regression indicates that gender of household head is an important factor, along with number of trees in the woodlot, in determining fuelwood sufficiency. Female-headed households were less likely to experience fuelwood shortage than male-headed households when the interaction with number of trees was included. Whether a woman in male-headed households must seek permission to harvest fuelwood, number of trees, and cooking with maize stalk were factors that predicted fuelwood shortage. Suggestions for several interventions to address fuelwood supply and access were included. Planting more trees in woodlots and use of fuelwood efficient stoves are two important strategies. It is important to address gender-specific priorities as they relate to woodlot use. This can be done through gender sensitizations that target program planners and male household heads. For successful programs, men and women should participate in both program planning and implementation. / Graduation date: 2003

Thesis (MScFor (Forest and Wood Science))--University of Stellenbosch, 2010. / ENGLISH ABSTRACT: The purpose of the study was to investigate the potential tree taxa that could be grown as a source of biomass in the Cape Winelands region. The trials comprises of two different aspects. The first being the estimation of potential volume, density and biomass of a pair of six year-old stands of E. gomphocephala and E. cladocalyx families at two climatically different sites within the study region. The second part of the study was the early growth assessment of alternative taxa that could be planted in the region compared to the regional mainstay E. cladocalyx. The volume of families was estimated using appropriate volume equations and using the form height were none were available. The best volume yield varied from 4.6 to 11.2 m3 ha-1a-1, at the dry and sub-humid sites, respectively. Wood density, estimated from non-destructive samples at both sites, varied from 620 (sub-humid) to 588 kg m-3 (dry site). The estimated biomass production rate of the top producing families yielded 2.7 and 6.9 t ha -1a -1 at the dry and sub-humid sites, respectively. In terms of estimated biomass and survival, E. gomphocephala was more suited to the dry site, while E. cladocalyx displayed superior yield than E. gomphocephala on the sub-humid site, but not significantly so. Early growth assessment of the trial of alternative taxa found that the hybrid E. grandis × camldulensis and E. grandis × urophylla had superior biomass indices, but were more susceptible to infestation by Thaumastocoris peregrinus and Gonipterus scuttelatus. / AFRIKAANSE OPSOMMING: Die doel van hierdie studie was om potensiële boom taksa vir gebruik as ’n bron van biomassa in die Kaapse Wynlandstreek te ondersoek. Die proewe behels twee aspekte: eerstens die beraming van die potensiële volume, digtheid en biomassa van sesjaaroue opstande met families van E. gomphocephala en E. cladocalyx by twee klimatologies verskillende groeiplekke in die studiegebied; tweedens die beoordeling van die vroeë groei van alternatiewe taksa wat in die streek geplant kan word in vergelyking met die streek se historiese staatmaker-spesie E. cladocalyx. Die volume van die families is beraam deur gebruik te maak van toepaslike volumevergelykings, en met behulp van ’n vormfaktor waar vergelykings nie beskikbaar was nie. Die volume aanwas by die droë en sub-humiede groeiplekke was onderskeidelik 4.6 en 11.2 m3 ha-1j-1. Houtdigtheid is beraam deur nie-destruktiewe monsters uit die opstand te neem. Gemiddelde digthede het variëer van 588 (sub-humied) tot 620 kg m-3 (droë groeiplek). Die beraamde biomassaproduksie van die top-families beloop onderskeidelik 2.7 en 6.9 t ha -1j -1 vir die droë en sub-humiede groeiplekke. In terme van beraamde biomassa en oorlewing, is E. gomphocephala meer geskik vir droër groeiplekke , terwyl E. cladocalyx by die sub-humiede groeiplek ’n hoër opbrengs as E. gomphocephala getoon het, hoewel nie betekenisvol nie. Beramings van die vroeë groei by die proef met alternatiewe taksa het getoon dat die basters E. grandis × camldulensis en E. grandis × urophylla hoër biomassa-indekse het, maar meer vatbaar is vir besmetting deur Thaumastocoris peregrinus en Gonipterus scuttelatus. / Centre for Renewable and Sustainable Energy Studies

This study addresses the question of people-centred development as a transformative aspect of the new South African development arena. The concept is defined as the involvement and active participation of people in the decision-making, evaluation and implementation of the development processes, It is one of the forms of democratisation which involves the decentralisaton of authority to the lower tiers of government. This study provides an analysis of the efficacy, relevance, advantages and disadvantages of people-centred development in the South African context. The Zikhoya-Ngqinisa Woodlot Trust Project was chosen as a case study, The reason was that through the process of devolution of the Department of Forestry and Water Affairs (DWAF), which involved the handing over of the management and financial resources of the small woodlots to the communities for their own benefit, the two villages, Zikhova and Ngqinisa, were given the Zikhova woodlot. The devolution of DWAF is one of the various forms of decentralisation that has given more autonomy to the lower tiers of government in the sense that the communities now have to satisfy their own needs. The main focus of the study was to identify and analyse constraints on the implementation of people-centred development specific to the Zikhova-Ngqinisa Woodlot Trust Project. Other interrelated aspects of people-centred development such as sustainability, community involvement and benefits of the project were also investigated and analysed. / KMBT_363

L’objectif est de distinguer les îlots boisés relictuels des néoformés dans une matrice agricole, de les recenser avant de les caractériser et d’évaluer leur biodiversité et pour finir d’en tirer un modèle. La méthode associe le recours aux archives et aux photographies aériennes à l’enquête de terrain (1996-2007). L’approche cartographique s’est faite par analyse régressive (2004-1620). Le seuil temporel permet de reconnaître 152 îlots (<50ha) dont l’existence est attestée avant 1620. L’analyse régressive s’appuie sur le réseau viaire, élément fixe et structurant du paysage, pour cartographier les petits bois.On constate une forte relation entre la localisation des îlots relictuels, les tracés antiques et les chemins médiévaux. La caractérisation et l’évaluation de la biodiversité des relictuels s’effectuent selon une démarche spatio-temporelle pluriscalaire, et à partir d’une comparaison avec les îlots néoformés. L’analyse à partir de la canopée informe sur la texture de la couverture boisée et la dynamique du manteau forestier, sur les coupes, les lisières et le réseau viaire intraforestier. L’analyse de la structure interne porte sur la diversité taxinomique et la diversité écologique des espèces végétales et des espèces aviaires indicatrices. Ces analyses font apparaître la spécificité des relictuels, dont est proposé un modèle. Il s’agit soit de fragments de forêts anciennes, soit en plus grand nombre de formations boisées secondaires mais anciennes, gallo-romaines, mérovingiennes ou médiévales. / The purpose is to distinguish the relictual forest islands from the recent ones in an agricultural matrix; to inventory and characterize them and to assess their biodiversity, and eventually to develop a model. The method combines the resort to archives and aerial photographs with field studies (1996-2007). The mapping approach has been based on regression analysis (2004-1620). The time threshold has made it possible to identify 152 woodlots (<50ha) which presence was attested before 1620. The regression analysis to map the wood patches has been based on the path network, which is a fixed and structuring element of the landscape. There is a strong relation between the location of the relictual forest islands, the antique tracks and the medieval paths. The characterization and assessment of the relictual forest islands biodiversity have been carried out following a time and space pluri-scalar approach and from a comparison with recent forest islands. The analysis was based on the shapeless canopy, the texture and dynamics of the forest cover, the cuttings, the edges and the internal forest path network. The analysis of the internal structure focuses on the taxonomic diversity and the ecological diversity of the plant species and the indicator bird species. These analyses have stressed the specificity of the relictual forest islands, a model of which has been developed. They are either fragment of ancient forests, or, in most cases, secondary but old forest forms from the Gallo-Roman, Merovingian or medieval time.
