Much public attention has been given lately to the concept of sustainability, a notion which is increasingly viewed as a desirable goal of viticulture development and environmental management. The emergence of the sustainability concept has seen a concomitant rise in the interest of its measurement. It has been suggested that through the analysis of regulatory and non-regulatory methods, the attainment of how sustainable freshwater use in vineyards can be assessed. Regulation has to date been the policy tool of choice in regards to environmental protection. While regulation is often necessary, non-regulatory approaches may, in some circumstances, serve as useful supplements to an effective regulatory regime. There are a number of stages to achieving the aim of this research. The first is designed at galvanising New Zealand‟s will to stride out down the sustainability road through the development of the sustainable vineyard concept. Investigations into regulatory freshwater policies were undertaken to assess the relative efficacy of such methods in guiding vineyards in sustainable freshwater use. The research then explored the elements of freshwater use as they relate to non-regulatory methods for achieving sustainable environmental outcomes. Qualitative research was undertaken through the instigation of an email questionnaire and semi-structured interviews to provide an understanding of freshwater use in vineyards within Marlborough. The research focuses on the discussion of the methodological considerations which are important in developing a working framework for assessing how vineyards achieve sustainable freshwater use. The ideal properties and characteristics of sustainability are identified and critically examined. An evaluation of the different types of regulatory and non-regulatory policies on freshwater management are considered. Both regulatory and non-regulatory methods were seen to be significant in developing an operational framework, as they are capable of representing the management of freshwater use and sustainability practices in vineyards. It is observed that the policy goal of both regulatory and non-regulatory organisations in achieving sustainable freshwater outcomes generally cannot be attained to the full satisfaction of all the dimensions of sustainability. Rather, sustainable freshwater use could be considered as a „road‟ and not a fixed destination. Along the way, trade-offs and balances have to be made. It is up to individual vineyard managers to weight the various alternatives, with the policy and decision makers providing information upon which rational choices can be based. This research demonstrates the efficacy of regulatory and non-regulatory methods in guiding sustainable environmental outcomes. It appears that the „ideals‟ of policies, as outlined in the literature and data collected, recommend an overall adaptive management approach if achieving sustainable freshwater use is the ultimate goal.

The Rural Energy Enterprise Development (REED) initiative provides assistance to energy-related enterprises to prepare them for growth and to make eventual investments by mainstream financial partners less risky. This study assesses the non-financial returns of a number of REED-type enterprises and provides guidance for the selection and ongoing evaluation of these enterprises within the context of development interventions. This study concludes that desired development outcomes should provide the basis for programme objectives against which non-financial returns can be measured. However, qualitative information is also necessary, as the context within which an enterprise operates largely defines the importance of these returns. Further work to improve the understanding of this context is necessary prior to the development of a formalised monitoring programme. Limitations of the assessment process should be recorded and addressed through the ongoing review of the programme, other monitoring efforts and further research.

Sustainable development is the modern rhetoric to guide environmental or natural resources management. There are many ways to do this and one concern the wider utilization of economic instruments, such as taxes or levies. Although such levies are becoming common in Australia and worldwide, the role of the taxes or levies is still limited. In many cases, these taxes/levies -although environmentally related- have a fiscal rather than a purely environmental motive, for example, the Natural Resources Management (NRM) Levy in South Australia. In South Australia, under the NRM Act 2004, all property owners are required to pay the NRM levy. Local governments collect the levy and distribute it to the relevant NRM board. The NRM boards have selected to calculate the levy on the basis of property value or simply applied a flat rate. The percentage of property value or the amount of the flat rate can vary amongst local government areas. How a tax or levy is designed should be determined by its ultimate purpose. Taxes or levies for fiscal and/or redistributive reasons should be designed in a way securing stable inflow of revenues, such as, levying on the values of property. However, this approach is often in sharp contrast with the goal of environmental taxes or levies which aim to change resource consumption behaviour. This study evaluates the NRM levy policy in South Australia using one NRM region and focussing on the urban community. The justification of this research is that few analyses of the effectiveness of environmental taxes or levies have ever been carried out, although the implementation of these measures has increased significantly during the last decades. There are fewer studies analysing the impacts of the tax or levy base method. This is the first study on this NRM levy policy from the perspective of the urban community who actually pay it. This study employed the Theory of Reasoned Action (Ajzen & Fishbein 1980) to examine the relationships between community attitudes to the levy policy and water consumption behaviour. Data was collected through a web-based survey with 770 respondents who answered 59 questions. The key findings show that governments are perceived to have the main responsibility for water resources management by respondents. However, there is huge information void towards the NRM levy policy. Community has few complaints about the levy level but strongly prefers to have a levy calculated on the volume of water consumed. Respondents also indicated that they would use less water if the levy were calculated on the volume of water consumed. The study makes contributions to relevant theory and policy analysis. Theoretically, the results show that the theory of reasoned action has limited strength in explaining the present research context. Practically, the study provides recommendations for policymakers and practitioners in South Australia, other Australian States, and internationally. The clear implications of the results suggest that if a tax or levy aims to change water consumption behaviour then it should be based on the volume of water consumed not on property value.

The complex co-evolutionary systems approach -CCeSA - provides a well-suited framework for analysing agricultural systems, serving as a bridge between physical and socioeconomic sciences, alowing for the explaination of phenomena, and for the use of metaphors for thinking and action. By studying agricultural systems as self-generated, hierarchical, complex co-evolutionary farming systems - CCeFSs -, one can investigate the interconnections between the elements that constitute CCeFSs, along with the relationships between CCeFSs and other sytems, as a fundamental step to understanding sustainability as an emergent property of the system. CCeFSs are defined as human activity systems emerging from the purposes, gestalt, mental models, history and weltanschauung of the farm manager, and from his dynamic co-evolution with the environment while managing the resources at his hand to achieve his own multiple, conflicting, dynamic, semi-structured, and often incommensurable and conflicting purposes while performing above thresholds for failure, and enough flexibility to dynamically co-evolve with its changing biophysical and socioeconomic environment for a given future period. Fitness and flexibility are essential features of sustainable CCeFSs because they describe the systems' dynamic capacity to explore and exploit their dynamic phase space while co-evolving with it. This implies that a sustainable CCeFS is conceived as a set of dynamic, co-evolutionary processes, contrasting with the standard view of sustainability as an equilibrium or steady-state. Achieving sustainable CCeFSs is a semi-structured, constrained, multi-objective and dynamic optimisation management problem, with an intractable search space, that can be solved within CCeSA with the help of a multi-objective co-evolutionary optimisation tool. Carnico-ICSPEA2, a co-evolutionary navigator - CoEvoNav -used as a CCeSA's tool for harnessing the complexity of the CCeFS of interest and its environment towards sustainability, is introduced. The software was designed by its end-user - the farm manager and author of this thesis - as an aid for the analysis and optimisation of the San Francisco ranch, a beef cattle enterprise running on temperate pastures and fodder crops in the Central Plateau of Mexico. By combining a non-linear simulator and a multi-objective evolutionary algorithm with a deterministic and stochastic framework, the CoEvoNav imitates the co-evolutionary pattern of the CCeFS of interest. As such, the software was used by the farm manager to navigate through his CCeFS's co-evolutionary phase space towards achieving sustainability at farm level. The ultimate goal was to enhance the farm manager's decision-making process and co-evolutionary skills, through an increased understanding of his system, the co-evolutionary process between his mental models, the CCeFS, and the CoEvoNav, and the continuous discovery of new, improved sets of heuristics. An overview of the methodological, theoretical and philosophical framework of the thesis is introduced. Also, a survey of the Mexican economy, its agricultural sector, and a statistical review of the Mexican beef industry is presented. Concepts such as modern agriculture, the reductionist approach to agricultural research, models, the system's environment, sustainability, conventional and sustainable agriculture, complexity, evolution, simulators, and multi-objective optimisation tools are extensively reviewed. Issues concerning the impossibility of predicting the long-term future behaviour of CCeFSs, along with the use of simulators as decision support tools in the quest for sustainable CCeFSs are discussed. The rationale behind the simulator used for this study, along with that of the multi-objective evolutionary tools used as a makeup of Carnico-ICSPEA2 are explained. A description of the San Francisco ranch, its key on-farm sustainability indicators in the form of objective functions, constraints, and decision variables, and the semi-structured, multi-objective, dynamic, constrained management problem posed by the farm manager's planned introduction of a herd of bulls for fattening as a way to increase the fitness of his CCeFS via a better management of the system's feed surpluses and the acquisition of a new pick-up truck are described as a case study. The tested scenario and the experimental design for the simulations are presented as well. Results from using the CoEvoNav as the farm manager's extended phenotype to solve his multi-objective optimisation problem are described, along with the implications for the management and sustainability of the CCeFS. Finally, the approach and tools developed are evaluated, and the progress made in relation to methodological, theoretical, philosophical and conceptual notions is reviewed along with some future topics for research.

The Resource Management Act 1991 (RMA) gave councils a mandate and an obligation to promote sustainability. Along with this it also introduced an expectation that the environment will be better managed than previously. Evidence shows that the environment is continuing to be degraded. This is especially evident in the coastal environment where in the early 2000s there has been unprecedented development pressure. The addition of the Local Government Act in 2002 (LGA) has strengthened councils’ sustainability mandate by stipulating a sustainable development approach and supporting processes and principles. Because the RMA and LGA have a similar sustainability directive there has been a push to utilise the compatible strengths that the LGA offers to enhance the outcomes achieved through RMA decisions, therefore, integrating and aligning the LGA and RMA. This research used case studies, including interviews, to examine how councils use their RMA and LGA mandates in coastal development decisions. The research found that currently there is little integration of the LGA’s requirements and sustainability direction in RMA coastal subdivision decisions. The case study analysis showed that using the principles and processes in the LGA and also a council’s policies, strategies, and plans other than RMA documents would provide up to date policy direction and contextual information that would be useful for RMA decisions and could provide a more sustainable outcome if used. The case studies identified a significant number of barriers to achieving sustainability through the RMA, including that much of the policy direction in RMA planning documents is not considered in deliberations. A number of these barriers are also likely to reduce attempts to integrate and align the LGA and RMA, unless they are addressed.
