Social and ecological insights across landscape, community, and household scales: Forest health, governance, and livelihoods in central India

Khanwilkar, Sarika Ann January 2023 (has links)
Forests are embedded in diverse forest governance, resource use, and resource user settings which are linked as components of social-ecological systems. This dissertation examines forest health at a landscape scale, governance at a community scale, and livelihoods at a household scale within a social ecological system; I develop a measure of forest health, the Bare Ground Index, derived from satellite imagery and combine this with socioeconomic data to examine relationships between forest health and forest governance and livelihoods across central India. This body of work has identified livelihood and governance approaches that provide social benefits and maintain healthy forests in central India, a landscape with globally important biodiversity and socially and historically marginalized people. This context is reflected in additional human-dominated landscapes where identifying sustainable development solutions that provide social and environmental benefits is a priority. As forests are lost, gained, and degraded around the world, satellite data has been a powerful tool in collecting estimates of forest cover change but less widely adopted to measure forest degradation, largely due to challenges in common interpretations of operational measures. In chapter 1, coauthors and I develop landscape-scale land cover and forest health datasets for central India. First, we identified land cover, including tree cover and bare ground, from Planet Labs Very High-Resolution satellite data using a Random Forest classifier, resulting in a 3-meter (m) thematic map with 83.00% overall accuracy. Second, we operationalize a measure of forest health and derived the Bare Ground Index (BGI), a normalized index that is a ratio of bare ground to tree cover at 90 m resolution. The BGI was mapped across forest (>10% tree cover). Although open areas occur naturally throughout the tropical dry forest of central India, results from field data indicated that the BGI served as a proxy for measuring the intensity of cattle presence in a landscape where grazing has changed forest composition. The BGI was developed as an indicator of forest health and now serves as a baseline to monitor future changes to a tropical dry forest landscape at an unprecedented spatial scale. In chapter 2, coauthors and I integrated the BGI with socioeconomic data from surveys to households and locally elected leaders to assess forest health and governance patterns across 238 villages at the community-scale. We experimentally selected 80 total villages as treatment and control groups and used this dataset in various statistical analyses to assess the extent of exposed bare ground within forests around villages with and without local institutions involved in making decisions about the forest. Forest had less bare ground within forest where there was a local institution compared to villages without an institution at 3 and 5 kilometers (kms), distances that households traveled from the village to graze cattle or collect Non-Timber Forest Products, firewood, and fodder. Having a local forest institution was more strongly associated with bare ground within forest at 3 and 5 kms than measures of local forest use. In villages with institutions, the authority to modify rules about forest use was relatively more important than the length of time the institution had been established for bare ground within forest. Establishing formal institutions with authority over forest management is important to promote forest cover around forest-dependent communities but it is necessary to ensure that forest governance does not worsen existing socioeconomic disparities. Bare ground within forests near and far (1 and 10 kms) villages was not different in places with and without formal local institutions and was most strongly associated with local forest uses. Both formal forest institutions and forest uses like collecting firewood for cooking or wood for construction material impact forests in central India. In my third and final chapter, coauthors and I examined firewood collection patterns and the adoption of Liquified Petroleum Gas (LPG) using surveys from 4,994 households in central India. Firewood collection is pervasive across central India’s rural communities and mainly used for cooking or heating. We adopted an energy justice approach, which emphasizes questions about who does and does not have access to alternative cooking fuels, because historically marginalized groups comprise a significant portion of central India’s total population. It was important to integrate social justice issues in a system where resource users experience multiple disparities, such as high levels of poverty. We found that despite overall growth in LPG use, disparities in access to clean cooking fuels remained and the probability of cooking with LPG was lowest for socially and historically marginalized households (i.e., Scheduled Tribe, Scheduled Caste, and Other Backward Caste). While 90% of LPG-using households continued to use firewood, households that have owned LPG for more years spent less time collecting firewood, indicating a waning reliance on firewood over time. This study found evidence that policies targeting communities with marginalized social groups living near forests can further accelerate LPG adoption and displace firewood use. My thesis examined components of a social ecological system at landscape, community, and household scales. I integrated insights from across social and ecological disciplines to identify strategies for sustainable development in central India. First, I developed an operational measure of forest health. Following chapters identified characteristics of governance and livelihood interventions that present potential pathways towards achieving benefits for conservation and people. Environmental and development goals should be harmonized so that the central Indian landscape can continue to support biodiversity and people. My approach can be replicated across additional social ecological systems by linking a landscape-scale resource condition to community governance and household socioeconomic patterns.

Reaching for sustainability: ecological modernisation and environmetal justice in South African energy policy and practice

Long, Dianne Patience January 2017 (has links)
A Dissertation submitted to the Faculty of Humanities University of the Witwatersrand, Johannesburg in fulfilment of the requirements for the degree of Doctor of Philosophy. April 2017 / Sustainable development is one of the major discourses of the twenty first century. In many instances sustainable development has been synonymous with the discourse of ecological modernisation. Ecological modernisation, as a discourse, has been proposed as an entreating means to reach the ideal of development that is sustainable, but has by and large only been tested within developed nations. There is, however, a prominent academic debate centred on the potential social and environmental justice concerns that may emanate from the promotion of ecological modernisation in environmental policy. This research project aimed to understand the degree to which ecological modernisation has been embraced in South Africa, and the environmental justice implications of this adoption. This was in an attempt to build an environmental justice policy framework for ecological modernisation in a bid to address environmental justice concerns. South African energy policy and practice was investigated in order to do this. Civil society hold an esteemed position in ecological modernisation, and as such in-depth, semi-structured interviews were conducted with a number of civil society activists who are involved in a range of campaigns for environmental justice. Their insights and solutions to potential environmental justice concerns that would result from using ecological modernisation were investigated. This was done in an attempt to build a list of environmental justice principles that can possibly be used to inform policies based on ecological modernisation in order to ensure just development. These criteria address the role of government, the role of society at large, as well as industry, and for the most part seek to understand if the disparate power dynamics that exist amongst these three actors can potentially be addressed. South African energy policies were analysed for evidence of these justice principles. It was found that South African energy policies do not address environmental justice in any measure that would truly allow for justice to be put into the practice of governing the environment. Therefore, by incorporating these environmental justice principles into ecological modernisation, ecological modernisation can potentially be stronger in approach to sustainable development than it presently is. / MT 2018

Disjointed Cosmopolitanism: Climate Change and Lived Experience in Portland, Oregon

Flinn, Stephen Wayne 04 October 2013 (has links)
Climate change has emerged as one of the most significant issues facing the world. This research endeavored to uncover and describe the lived experience of Portland, Oregon residents in relation to the substantive issue of climate change. The specific purpose of this research was to gain a better understanding of the ways that Portland residents conceive of and communicate about climate change. Utilizing semi-structured phenomenological interviews, particular attention was paid to the culture of Portland residents, their lived experience and how the issue of climate change manifests itself in their everyday experiences. In addition, this particular phenomenological inquiry incorporated elements of auto ethnography by positioning the researcher`s experiences, imagination and intellect at the center of the research endeavor. Multiple themes emerged from the in-depth, descriptive interviews that helped to reveal the structure or essence of the participant`s experience(s). A single meta-theme was identified and informed by contemporary theories such as Cosmopolitanism and the Environmental Justice Paradigm.
