Albert Einstein believed “we can't solve problems by using the same kind of thinking we used when we created them.” This quote, in my opinion, is particularly relevant for the academic literature that examines individual energy use. I believe that we have historically taken a categorized approach towards looking at individual energy use. Instead of thinking about multiple behaviours widely, we tend to look at individual behaviours deeply - focusing on electricity use, gas use, or travel behaviour in isolation instead of examining them simultaneously. For this reason, this thesis explores if and how an intervention aimed at one energy behaviour may influence or have untargeted effects on other energy behaviours across household energy use and personal travel behaviour from an interdisciplinary research perspective. The relevant literature is reviewed and an innovative methodology is devised to answer the research questions. By examining quantitative and qualitative data, the thesis evaluates the targeted and untargeted effects of an electricity display study across household energy and travel behaviours, assesses the influence that social and technical experiences with the display may have on behaviour, and explores how individuals conceptualize their energy usage to better understand untargeted effects. The findings indicate that 1) in a sample of 19 participants, 15 had untargeted effects in gas and 4 had untargeted effects in gas and travel, 2) the combined effect of social and technical experiences with the display can explain why an untargeted effect did or did not take place, and 3) participants perceived household energy as a resource but perceived travel as a means to move from one place to another. These findings lead to the development of a novel contribution of this research, known as the tangential effect. Contributions to theory and policy, an assessment of the methodological approach, and future research areas are given.

Glaciated catchments increasingly accommodate rising populations. As glaciers are capable of modifying peak flows and releasing floodwaters, understanding and developing models of subglacial water storage and release has significance to the safety of resident populations and land use decision-making. Glaciological and hydrometeorological processes play a critical role in determining water storage within the subglacial drainage system of Alpine glaciers. However, our understanding of spatial variations of these processes throughout the ablation season remains incomplete. Field results and modelling studies of the glacial hydrological system at Findelengletscher, Canton Valais, Switzerland are presented with a view to improving understanding of physical mechanisms controlling water flow within glacierised catchments. A physically-based model of surface runoff incorporating meltwater and precipitation has been developed. This model has limited data requirements using only air temperature, solar radiation, precipitation and elevation of the transient snow line in a simple, spatially distributed energy balance model. It has been used to predict surface runoff at an hourly resolution for the 1999 ablation season. Methodological advances have been made by creating conceptual models of water flow through the subglacial drainage system. Models are used for semi-quantitative interpretation of water level variations in boreholes, as surrogate measures of subglacial water pressures. The boreholes either directly intersect subglacial channels or hydraulically connect to subglacial channels through a subglacial sediment layer. Variations in borehole water levels are considered at both diurnal and seasonal timescales. Water storage has been calculated within the subglacial drainage network and interpretations are made of temporal variations in subglacial water storage. Borehole water levels indicate that the glacier subsole can be spatially separated into those areas that are hydraulically connected or unconnected to the subglacial drainage system. Hydraulically connected areas may further be subdivided into areas of efficient and inefficient subglacial drainage. These may intermittently connect and influence water balance within a glacier. Increasing and decreasing trends in water balance cycles are initiated by glaciohydrological mechanisms. These control the activity of intermittent hydraulic connections between efficient and inefficient areas of subglacial drainage. Connections form in response to two hydrometeorological factors: high elevation rainfall and short duration decreases in elevation of either the snowline or the 0°C isotherm. Increasing trends in water balance over successive days are associated with preferential routing of inputs into, and retention within, hydraulically inefficient areas of the subglacial drainage system. Occasionally the release of water from temporary subglacial storage is not synchronous with either hydrometeorological causal factor. Measurements of fall-line velocity and vertical displacement suggest that basal sliding may alter preferential subglacial flow pathways. However, uncertainty exists as to whether such changes may be the result of lagged effects of either high water pressures from rainfall or low water pressures from low daily surface runoff. These uncertainties are due to system response times affecting the time taken to transfer longitudinal strain within glacier ice. In the late ablation season the potential for rapid surface runoff over the annual maximum snowfree area within the catchment is high. In the event of a large rainfall event the capacity of a tunnel-conduit system to discharge may have decreased sufficiently to cause temporary retention of a large proportion of surface runoff, predominantly within distributed drainage. Temporary storage followed by re-integration of hydraulic connections formed earlier in the ablation season, increases the potential for proportionally large discharge events (relative to the volumes of inputs) in the late ablation season. Flooding in glacierised basins becomes more likely as a result.

Kingston is a city facing serious environmental challenges. In common with other Third World cities, these have usually been documented from the perspective of affluent and powerful urban residents. Very little research has explored the spatial and social distribution of environmental problems in the city, or has examined the ways that individual citizens from a variety of backgrounds understand the urban environment. These problems have often been packaged as discrete issues, when in fact they cannot be understood or alleviated without knowledge of their economic, political, and cultural aspects. Urban environmental problems require political solutions that address uneven power relations and ineffective structures of urban governance. In this thesis, I address these issues in Kingston through an application of the themes of nature, power and participation. A mixture of qualitative and quantitative methods were used to explore the ways in which urban residents from different age, gender and class backgrounds construct the city and its environmental problems. The knowledge of marginalised individuals and groups is placed in the foreground and is used to provide an alternative analysis of Kingston’s ecology. These understandings are then used to assess critically the structures of urban governance, and to suggest possible changes that could be made to these. The research confirms that there are significant environmental problems in Kingston, and that these have serious negative impacts on many urban residents. It shows that these problems are understood differently by the various social groups within the city, and that the burdens of environmental problems vary socio-spatially across the Kingston Metropolitan Area. Despite this, there is a general consensus that environmental improvement is desirable. However, for this to be achieved there need to be fundamental alterations in the social structures and political organisation of the city.

The oases of the northern Sahara illustrate the possibility that people and nature can work together to enhance life in a harsh and variable environment. This research investigates fifty years of experiences of living with environmental change in oasis systems, bringing together new data, archived environmental records and cultivators` observations. These are combined to gain insight into the environmental change processes, and the experiences gained by people through living with them in this regional context. Two detailed case studies deepen understanding of the socioeconomic dimensions and significance of these changes over the past two decades. The findings show how environmental changes constrained smallholders` traditional ecosystem management practices. Collective associations were weakened or disintegrated. National systems for environmental management and monitoring were overwhelmed. International recommendations for economic approaches to resource management and innovation to address water scarcity did not prove effective. On the other hand, instances where the international market transition appeared to be creating new opportunities for the restoration of common pool resource management were also identified. This investigation enabled a new perspective on the global dryland management debate to be generated in a context where research has most commonly been concentrated on national sectoral objectives for productivity and desert reclamation. Theoretical insights regarding the application of interdisciplinary research to understand environmental change, further research needs, and potential solutions are directly transferable to other regions where desiccation, salinization and groundwater degradation are accelerating due to climatic and global market-driven changes in land and water use.

The destruction of tropical forests is the most concerning current threat to biodiversity. Although protected areas have long been used as the primary tool for biodiversity conservation, there is an increasing need to find suitable conservation strategies for the growing area of human-modified land. This thesis addresses three themes that have been identified as the most pressing areas for research in human-modified landscapes: biodiversity conservation beyond protected areas, forest restoration, and the human–environment relationship. By studying the interactions between birds, plants, and people with isolated Ficus (Moraceae) trees in Assam, India, this thesis reports several important findings: 1) isolated Ficus trees are extraordinarily important to frugivorous bird communities that inhabit human-modified landscapes; 2) the frugivores visiting these isolated trees still sustained the majority of ecological function found in trees close to the forest edge; 3) isolated Ficus trees are also exceptionally important feeding sites for insectivorous birds in human-modified landscapes, compared to other trees; 4) Ficus trees are better restoration nuclei than other isolated trees; 5) although the sacred status of Ficus trees in Assam has a major influence on their abundance and distribution, faith-based values are insufficient in ensuring their conservation. In conclusion, this thesis finds that isolated Ficus trees are critically important micro-sites for conservation in human-modified landscapes, the loss of which may lead to avifaunal collapse and a reduction in restoration potential. However, by stressing their ecological and cultural properties, it may be possible to build a strong case for the conservation of isolated Ficus trees in Assam and elsewhere.

This doctoral dissertation examines the mode and efficacy of environmental and climate policy in China’s automotive sector. The ascent of China’s automobile market to the largest worldwide has detrimental effects on the country’s energy security situation, worsens environmental pollution, and increases greenhouse gas emissions. Environmental and climate policy measures to ameliorate these repercussions are the most apt tools available to the Chinese government. The objective of this dissertation is to identify the dominant mode of environmental and climate policies in China’s automotive industry and to assess the efficacy of select policy instruments. It does so by asking whether a uniform national approach to policy instrument adoption can be discerned that reflects China’s institutional and administrative history or whether modal exceptions exist. Secondly, if modal differences exist, to what extent do different instruments confirm the current understanding of the advantages and pitfalls of individual policy instrument types? And finally, how do Chinese instruments compare to those in other ambits in terms of policy mode and instrument efficacy? The literature on policy instruments holds that, due to their alleged efficiency advantages, incentive-based instruments dominate the political agenda of industrialised countries and international organisations (environmental consensus). This favouring of flexible instruments in academic and political circles contrasts with an evident lack of incentive-based instruments in practice and an observed lack of efficiency of some of those instruments actually implemented. Moreover, the policy mode adopted in developing countries and emerging markets has not yet received sufficient academic attention despite significant differences in institutional design, enforcement capacities, resources, and development paths that may imply reason for modal deviation. Applying a blend of qualitative and quantitative social sciences research methods, I add the case of China to the comparative literature and show that command-and-control regulation indeed forms the backbone of environmental and climate policy in China’s automotive industry. At the same time, modal differences exist between national regulation and local/ municipal incentive-based policy as well as in the electric vehicle sector, which shows a trend towards more incentive-based instruments and flexibility mechanisms in conventional regulation. Compared to other ambits, China has established a relatively flexible policy regime, at least for the case of vehicle efficiency standards. For the time being, incentive-based instruments remain comparatively ineffective and flexibility mechanisms in conventional regulation have an erosive effect on instrument stringency.

This thesis sets out to explore the implications that transport infrastructures have on the production and perception of the urban built environment. Particularly, it focuses on the Victorian brick viaducts constructed to support the elevated railway in Manchester, England. It concentrates on Manchester’s post-industrial restructuring and re-imaging since the late 1960s, exploring how the presence of brick railway viaducts, as well as the uses beneath their arches, have impacted strategies for revalorisation in the wake of gradual deindustrialisation. In exploring the changing symbolic economy of landscapes dominated by railway infrastructure, as well as the shifting uses and images of railway arches, this thesis explores the interplay between political economy and the aesthetic and symbolic dimensions of urban regeneration. Upon establishing the mutually constituted history of Manchester’s elevated railways and its city centre and demonstrating how this 19th century process has shaped the form and character of the city, it excavates a cultural history of the infrastructural landscapes of the city. Special emphasis is placed on the uses and perceptions of railway arches, which have long served as symbols of dereliction and social disorder. These spatial and cultural histories act as a foundation for analysing how the city’s railway viaducts have been implicated in the re-imagining of Manchester as a post-industrial city. These histories and representations are explored in relation to property-led strategies of environmental improvement, industrial displacement, and heritage tourism along the southern fringe of Manchester city centre, focusing on three thematic and spatially bound case studies. These case studies rely on documentary data of planning and design strategies, interviews with elite actors involved in the re-imaging of Manchester city centre, and ethnographic observation. Using critical discourse analysis, the thesis unpacks the narrative relationship between dominant representations of these spaces and professional justifications for their material and symbolic reconfiguration.

This thesis examines the relationship between environmental stress and human mobility with a view to understanding the impacts of climate change on human migration. Using a conjuncture of political ecology and migration theory, it firstly explores the literature on 'environmental refugees' identifying a distinction between general agreement on the existence of a relationship between environmental stress and migration, and debate over the appropriateness of the 'environmental refugee' as a suitable means for representing that relationship. Secondly this conjuncture is used to examine accounts from farmers and migrants in northern Ethiopia, with a focus on understanding how environmental and non-environmental factors interact to shape mobility decisions in a context of environmental stresses, thought analogous to those predicted to accompany future climate change. The principal finding of the study is that although environmental stress matters in mobility decisions, it does so due to the context of non-environmental factors in which it occurs, not in spite of them. With this in mind the work provides a framework of additive, vulnerability, enabling and barrier effects as a means for elaborating our understanding of how environmental and non-environmental factors interact to determine mobility strategies in a context of environmental stress. Focussing on the role of non-environmental factors, the work reveals that while biophysical features operate at a macro-scale to shape mobility decisions, these decisions are determined by non-environmental features operating at a micro-scale. The research then traces differences in the existence of these micro-scale, non-environmental, factors across two field sites, finding that their origins lie in both historical and contemporary forces of regional and global political economy. As such, the work concludes that understanding the relationship between climate change and human migration will require a contextualisation of that relationship within this broader framework.

The recent revival of debates concerning livestock development in Africa follows the more widespread acceptance of paradigm shifts within rangeland science, and maintaining pastoral mobility is now recognised as fundamental for the future survival of pastoralism and sustainability of dryland environments. However, in southern Africa communal pastoral drylands continue to be enclosed and dissected by large-scale barrier fences designed to control livestock diseases, thus protecting lucrative livestock export agreements. This interdisciplinary research examines the extent to which these veterinary cordon fences have changed people’s access to, and effective management of, natural resources in northern Botswana and how fence-restricted resource use by livestock, wildlife and people has changed the natural environment. Critical political ecology informed the approach, given its emphasis on socio-political and historical influences on resource access, mobility and user relationships. This enabled the biophysical effects of social changes to be investigated fully, thereby moving beyond a tradition of discipline-based studies often resulting in severely repressive rangeland policies. The research demonstrates how enclosure by veterinary cordon fences restricts patterns of resource access and mobility within pastoral drylands, with serious implications for both social and environmental sustainability. Enclosure increases the vulnerability of people to risks and natural hazards, while resource access constraints and pastoral adaptations to enclosure have favoured the increasing commercialisation of livestock production, thus obstructing pathways into pastoralism. While widespread environmental change in livestock areas cannot be attributed thus far to enclosure, the curtailment of wild migratory herbivores at the wildlife–livestock interface has caused some large-scale structural vegetation changes and there are indications that fence induced sedentarisation could be accentuating existing degradation trends. Given these changes, future rangeland policies in Africa should be aware of the social and environmental impacts associated with export-led disease management infrastructure and consider alternative, less intrusive, approaches to livestock development and disease control in extensive pastoral drylands.

A policy mechanism known as REDD+ (‘Reducing Emissions from Deforestation and forest Degradation, and enhancing forest carbon stocks and conservation’) is designed to contribute to climate change mitigation efforts and simultaneously support developing countries’ national development agendas. This is effected by providing REDD+ host countries with financial incentives to produce measurable reductions in carbon emissions beyond what would have occurred without REDD+. Indonesia is a key target of the REDD+ mechanism for several reasons, eg: (i) its forests support 10% of the world's remaining tropical rain forests and represent the fourth largest forest carbon stock globally, (ii) 80% of its GHG emissions result from deforestation and forest degradation, and (iii) it has the potential to reduce up to 120 million tons of CO2 per year. Consequently, to date Indonesia has received donor’s commitments of nearly US$2 billion for REDD+ development. Given this profile, Indonesia’s success in implementing REDD+ can contribute significantly to the efficacy of REDD+ globally. However, achieving this potential is undermined by a set of long-standing problems inherent within Indonesia’s forest institutions, including issues of corruption, coordination, uncertainty in the forests’ legal system, capacity to manage forests at multiple levels of government, and the use of forest concessions to consolidate political power. This thesis asks the primary research question: <b>“How do REDD+ institutions effect governance reform within Indonesia’s existing national and sub-national forest institutions?”</b> 'Institutionalism', in particular the concept of 'institutional interplay' is the main conceptual framework deployed and grounded in the context of the vertical interplay between the internationally-formulated REDD+ mechanism and Indonesia's forest institutions. Guided by the themes that emerged from the data collected, this research explored and expanded certain analytical approaches within the perspectives of institutionalism and governance, namely ‘historical institutionalism’, ‘clientelism’, 'critical juncture', ‘policy networks’ and ‘social learning’. This thesis adopted the ‘four paper route’ and employed mixed methods of data collection (ie interview, shadowing, and policy document review). It found that during the process of institutional interplay as REDD+ institutions deployed the principles of good governance, advanced a robust system of measurement, reporting and verification of reductions in carbon emission, attracted large funding, and involved a broad range and multi-scale of actors, the REDD+ mechanism produced 'collateral benefits'. The tangible form of these benefits was the production of new policy instruments, eg the 'national REDD+ strategy' (paper 2), 'one map initiative' (paper 3), and ‘village agreement’ (paper 4) through which a significant body of evidence showed the capability of REDD+ to effect governance reform within and beyond Indonesia's forestry sector. Paper 1, revealed how policy actors perceived REDD+ and as such provides the basis of these three papers. The positive results of institutional interplay that occurred were determined not only by the characteristic of REDD+ institutions themselves but also by the existence of domestic reformists and the national reform agenda.
