Re-Linking Governance of Energy with Livelihoods and Irrigation in Uttarakhand, India

Buechler, Stephanie, Sen, Debashish, Khandekar, Neha, Scott, Christopher 08 October 2016 (has links)
Hydropower is often termed "green energy" and proffered as an alternative to polluting coal-generated electricity for burgeoning cities and energy-insecure rural areas. India is the third largest coal producer in the world; it is projected to be the largest coal consumer by 2050. In the Himalayan state of Uttarakhand, India, over 450 hydroelectric power schemes are proposed or are under development. Hydropower projects ranging from micro hydro (run-of-the-river systems with generating capacity up to 100 kW) to large reservoirs (storage systems up to 2000 MW) such as the Tehri Dam are in various stages of planning, construction or implementation. Run-of-the-river hydropower projects are being developed in Uttarakhand in order to avoid some of the costs to local communities created by large dams. Stakeholders in this rapid hydropower expansion include multiple actors with often diverging sets of interests. The resulting governance challenges are centered on tradeoffs between local electricity and revenue from the sale of hydropower, on the one hand, and the impacts on small-scale irrigation systems, riparian-corridor ecosystem services, and other natural resource-based livelihoods, on the other. We focus on the Bhilangana river basin, where water dependent livelihoods differentiated by gender include farming, fishing, livestock rearing and fodder collection. We examine the contradictions inherent in hydropower governance based on the interests of local residents and other stakeholders including hydropower developers, urban and other regional electricity users, and state-level policymakers. We use a social justice approach applied to hydropower projects to examine some of the negative impacts, especially by location and gender, of these projects on local communities and then identify strategies that can safeguard or enhance livelihoods of women, youth, and men in areas with hydropower projects, while also maintaining critical ecosystem services. By assessing the Bhilangana basin case, we also offer hydropower-livelihoods-irrigation nexus lessons for headwater regions across the Himalayas and globally.

Urban Ecosystem Services : The Value of Green Spaces in Cities

Langemeyer, Johannes January 2015 (has links)
In an ever more urban world, the role of green spaces in cities is increasingly highlighted for their capacity to provide ecosystem services for human well-being. Yet, the value of urban green spaces is still widely overlooked in urban policy and planning. This dissertation examines the evidence base for the multi-functionality and values of urban green spaces, in the context of decision support and for priority setting in urban policy and governance. First, the multi-functional character of urban green spaces and the many benefits they provide to humans through the delivery of ecosystem services is studied through a literature review. Secondly, the pluralism of values is examined through case studies from urban green spaces in Barcelona, Spain. Within these case studies, value perceptions, value emergence and value dimensions are scrutinized by combining different methods, including remote sensing, participatory observations, interviews, surveys, statistical analysis and geographical information systems. Finally, pathways for an integrated valuation of ecosystem services in urban planning are explored through a review of state-of-the-art knowledge on multi-criteria decision analysis applied in relation to ecosystem services. The dissertation shows the multi-functional character of urban green spaces and outlines their specific importance for the provision of cultural ecosystem services. It contributes to operationalize the perspective of value pluralism in the assessment of ecosystem services from urban green spaces. It is noted that the perception of diverging values is mainly determined by the characteristics of the ‘valuator’, the socio-institutional context, as well as different valuation languages through which values are assessed. The perspective of value pluralism endorsed in this thesis, underlines the need for an integrated valuation of ecosystem services to inform decision-making and governance. The thesis examines the potential of multi-criteria decision analysis as a tool to facilitate such integrated valuation of ecosystem services, in the context of urban planning. By putting forward the value of ecosystem services for humans, the thesis intents to provide a cornerstone for policies towards more sustainable and resilient cities that recognize the interconnection and dependency of cities on healthy ecosystems worldwide.

Sustainable forests: A strategy for climate change adaptation and mitigation? : A case study from Babati District, Tanzania

Hall, Elin January 2009 (has links)
<p>This Bachelor‟s thesis aims at explaining the relationship between forests and climate change, a subject that has been given a lot of attention in environmental discussions in recent years, particularly because forests are a source of carbon dioxide emissions and in the same time have the potential to mitigate climate change through carbon sequestration. However, with the importance of mitigation as a background, the focus of this study is on adaptation. The purpose is to identify mutual benefits from the diverse forest ecosystems, and examine the possible benefits from forests to the rural poor population in Tanzania, in a future scenario of increased vulnerability to climate change. The methodology for the study can be divided into two parts, one qualitative literature study and one field study in Babati District northern Tanzania, limited to interviews and excursions. This thesis gives details about the scientific projections and local perceptions of climate change and the effects of climate change. The results of the thesis highlights the importance of sustainably managed forests and agroforestry systems, which have been successful in Babati through local participation; economic incentives such as carbon credit and other payments for ecosystem services, which is a possible future extension of forestry activities; and increased integration between sectors, which make sure that adaptation within different sectors can be done simultaneously.</p>

Vilka våtmarker saknas i Naturvårdsverkets inventering? : En inventering av våtmarker under 10 ha i Laholms kommun, Halland, och deras potentiella ekosystemtjänster

Kindström, Marie January 2014 (has links)
Small wetlands are often ignored in inventory studies; consequently they are less protected and therefore more vulnerable. Moreover, previous research indicates the importance of small wetlands as they can provide important ecosystem services to human kind. The Environmental Protection Agency of Sweden has carried out a national wetland inventory, however they have applied a limited area, which consequently excludes smaller wetlands. This study aims to make an inventory of the excluded wetlands smaller than 10 hectares in Laholms municipality, Halland. In this inventory study I have applied GIS as a method by comparing different map layers, such as aerial photos, land cover data and Google Earth. Furthermore, the study aims to investigate the ecosystem services provided by the located wetlands in the study area and discuss how this exclusion could affect the services. The results of the inventory indicate that 745 wetlands are missing in the Environmental Protection Agency inventory, which correspond to 12 percent of the total wetlands in Laholms municipality. The results also indicate that 99,1 percent of the missing wetlands are mire and 0,9 percent are riparian wetlands. In the literature study I found that mire provides ecosystem services such as carbon storage, material such as peat, and unique habitats for biodiversity. Riparian wetlands provide ecosystem services such as unique habitats for biodiversity, improving the quality of the water, reduce fertilization and provide recreational values. Moreover, both type of wetlands are also important to the wetland mosaic in order to maintain proliferation and the local hydrological systems.  Additionally, small wetlands are especially important to invertebrates and amphibians. Though, if the small wetlands in Laholms municipality continue to be ignored then the benefits of the ecosystem services mentioned above are likely to be reduced and limited.

Aquaculture in Lake Storsjön: an ecosystem services based investigation

Marcianò, Pietro January 2015 (has links)
The purpose of this thesis is to investigate if the application of the ecosystem services concept can provide decision makers and stakeholders with additional relevant information for decisions regarding establishing of aquaculture on a local level, using the Lake Storsjön as a case study. In order to provide this knowledge, three different tasks are carried out within this thesis: the identification of the main ecosystem services provided by Lake Storsjön, the understanding of ecosystem services that will be affected by the expansion of aquaculture and the identification of the services that will be used for a possible expansion of the aquaculture sector. The CICES methodology (Common International Classification of Ecosystem Services) is used to identify the ecosystem services provided by Lake Storsjön. The understanding of the affected ecosystem services is carried out with the use of a Delphi-inspired approach. The identification of the services required for the establishment of aquaculture is driven by a cross-reference matrix. Lake Storsjön provides thirty-nine out of the fifty-nine ecosystem services included in the CICES. About half of these will be effected by environmental impacts connected to operations of ecosystem management required by aquaculture expansion, mostly with a low or medium degree of impact. An increase in the implementation of aquaculture might cause detrimental trade-offs with these ecosystem services: “Wild animals”, “Genetic materials from all biota“, “Disease control”, “Maintaining nursery populations and habitats” and “Filtration/dilution/sequestration/storage/accumulation by ecosystem”. An expansion of the aquaculture sector requires seven of the ecosystem services provided by Lake Storsjön. The vital services for this process are: “Surface water for non-drinking purposes”, “Filtration/dilution/sequestration/storage/accumulation by ecosystem” and “Chemical condition of freshwater”. These services have to be safeguarded and maintained in order to guarantee adequate conditions for an expansion of this sector. At the same time the expansion of aquaculture supports the service “Animals from in situ aquaculture”. The benefits connected to the implementation of aquaculture shall be economically assessed and compared to the actual economic value delivered by the other ecosystem services in order to further understand the positives and negatives outcomes of aquaculture expansion in an ecosystem services perspective. This is considered to be a relevant step for strategic and decision making processes concerning aquaculture expansion in Lake Storsjön. In addition to the economic perspective, it seems that the most relevant factor when discussing planning and development processes towards ecosystem services is the importance of not overshooting the resilience ability of the ecosystem in order to ensure the accessibility of the services to future generations. This belief is recommended to be applied to Lake Storsjön in order to guarantee a conscious expansion of the aquaculture sector on a social, economic and environmental level.

Stakeholder process within limestonequarrying and potential impacts onbiodiversity and ecosystem services. Case study of Bunge Ducker,Northern Gotland, Sweden

Shirnina, Elena January 2014 (has links)
Mining has always played an important role in human development. The growing demand for miningnowadays puts under threat biodiversity and ecosystem services, which leads to many conflicts based on choicebetween environment protection and social and economical development. Studying a case of a limestone quarryon Northern Gotland as one of the most representative cases of such conflict, gave an opportunity to investigateand analyze the cost of the decision-making in mining as well as interaction between stakeholders affecting andbeing affected by the decision from the perspective of the group opposing to mining. The research showedweakness of communication between the stakeholders; the weakness of the argument supporting social andeconomical development and giving it higher priority than the environment; and the best possible solution whichwould be turning the whole area of interest into a national park, even though such solution would not fulfilltheinterests of the mining company.

Ekosystemstödjande och multifunktionella växtval i urban miljö : En fallstudie med utgångspunkt i Nacka stadsbildning

Åshage, Anna January 2014 (has links)
This study has investigated how urban vegetation can be used in a multifunctional way to support ecosystem services in urban environments. Nacka municipality is in the start-up phase of building what is to become Nacka city. This provides a unique possibility to study and analyse what role the vegetation play in making the city a healthy living environment and how it needs to be adapted in order to be resilient against changing climate conditions and how the effects of those changes can be regulated. The study further investigates how airborne pollution, caused by urbanization processes, can be regulated or reduced by vegetation or species selection. Methods used in this study were a combination of qualitative interviews and literature studies, seeking to answer the questions: Which specific ecosystem functions are needed in the urban environment and which aspects will influence the ecosystems ability to deliver the functions in demand? And which plant species have the right mechanisms needed to deliver those functions? These questions have been studied and analysed in a local based context where the local conditions ands site specific needs of Nacka define criteria for plant selection. Based on those criteria, a plant list is presented that seeks to find synergies and effectiveness in plant selection with the aim to find plants that support and/or produce multiple ecosystem functions.
