Spreading The Char: The Importance of Local Compatibility in the Diffusion of Biochar Systems to the Smallholder Agriculture Community Context

Munoz, Laura C. V. 01 May 2014 (has links)
This thesis enters the context of smallholder agriculture communities in the developing world. It explores the potentials of biochar and what biochar systems could bring to the smallholder communities while simultaneously bringing environmental benefits. It then acknowledges the challenges of diffusion –the spreading of an unfamiliar innovation. It seeks to answer the question of what will make diffusion of biochar systems more successful in the smallholder context, fixating on the characteristic of compatibility as well as the role local community members can play in making a new biochar system more visible to the rest of the communities.

Producing Collaborations Through Community-Level Processes of Climate Change and Water Management Planning

Mic, Dumitrita Suzana 02 July 2015 (has links)
While much attention has been given to the ways local communities may be impacted by climate change, this dissertation focuses ethnographically on the local agencies decision-making processes, a less-studied aspect of this topic. The primary purpose of this dissertation research is to understand how government agencies in southern Florida integrate climate change into their decision-making processes while dealing with political resistance. This research expands our understanding on the cultural politics of a new kind of environmental change, where national and international climate-change politics is brought into local water politics to illuminate how new and not so new visions about life in the contemporary metropolis collide and collude. Using multiple research methods including ethnographic fieldwork, participant observation, semi-structured interviews, and document research, I analyze the activities of the Miami-Dade County Climate Change Advisory Task Force Committee (MDC-CCATF) as well as the water management practices of the regional water management agency, the South Florida Water Management District (SFWMD). My findings include the following: (1) the Task Force activities have spearheaded Miami’s institutional adaptation to climate change; (2) historic legacies have expanded and complicated decision-making processes at the District; (3) a focus on the certainties of climate-change science allows climate change to persist in politically contentious planning contexts. My dissertation concluded that while planning for potential climate-change impacts can be difficult due to multiple institutional constraints that resource agencies like the District have, scientists and policy-makers have crafted an innovative culture that is particularly visible at sites where science and decision making intersect.

Can NGOs cultivate supportive conditions for social democratic development? : the case of a research and development NGO in Western Uganda

King, Sophie January 2013 (has links)
There is an emergent consensus that the ‘poverty reduction through good governance’ agenda has failed to meet expectations. The capacity of non-governmental organisations (NGOs) to cultivate the political economies and state-society synergies that might be supportive of more pro-poor development trajectories is contested. Advocates of inclusive liberalism identify increased political space for NGOs focused on popular empowerment and policy influence within the participatory spaces created by the good governance agenda. More radical critiques cast NGOs as apolitical brokers of neo-liberal development resources which distract from or are disinterested in more fundamental questions of redistribution. This thesis explores the potential for Ugandan NGOs to cultivate supportive conditions for a more redistributive development process amidst a semi-authoritarian, patronage-based, political regime and within a predominantly agrarian economy, using the lens of a single case study organisation situated in the Western region of the country. The findings suggest Ugandan NGOs should move beyond strategies associated with inclusive liberal governance towards a closer engagement with the politics and political economy of progressive change. Micro-enterprise and economic associational development emerge as more effective enhancers of political capabilities among the poor than strategies aimed solely at promoting inclusive liberal participation because they can tackle the socio-economic power relations that curb political agency in such contexts, and begin to undermine patronage-politics. In contrast, strategies for enhanced inclusive liberal participation engage with the formal de jure rules of the game in ways that either sidestep or re-enforce the de-facto patronage-based political system and fail to tackle the power relations that perpetuate ineffective forms of governance. Creating new cross-class deliberative spaces which engage with grass roots perspectives, can facilitate the emergence of new ways of thinking that promote a more pro-poor orientation among development stakeholders. Triangulation of qualitative primary data and relevant literature leads to the overarching conclusion that NGOs operating in such contexts are more likely to enhance the political capabilities of disadvantaged groups by adhering to a principle of self-determination. This focuses energy and resources on non-directive facilitative support to disadvantaged groups. This enables them to a) make socio-economic progress; b) become (better) organised; c) develop the necessary skills and knowledge to advance their interests; and d) cultivate opportunities for direct engagement with power holders and decision-makers. This approach requires a high level of what the thesis terms ‘NGO political capacity’ and a far more open-ended and programmatic approach to the provision of development aid than currently prevails.

Modeling Spatial Distributions of Tidal Marsh Blue Carbon using Morphometric Parameters from Lidar

Turek, Bonnie 05 April 2023 (has links) (PDF)
Tidal marshes serve as important “blue carbon” ecosystems that accrete large amounts of carbon with limited area. While much attention has been paid to the spatial variability of sedimentation within salt marshes, less work has been done to characterize spatial variability in marsh carbon density. Driven by tidal inundation, surface topography, and sediment supply, soil properties in marshes vary spatially with several parameters, including marsh platform elevation and proximity to the marsh edge and tidal creek network. We used lidar to extract these morphometric parameters from tidal marshes to map soil organic carbon (SOC) at the meter scale. Fixed volume soil samples were collected at four northeast U.S. tidal marshes with distinctive morphologies to aid in building our predictive models. Tidal creek networks were delineated from 1-m resolution topo-bathy lidar data using a semi-automated workflow in GIS. Sample distance to tidal creeks and flow distance to the marsh edge were then determined. Log-linear multivariate regression models were developed to predict soil organic content, bulk density, and carbon density as a function of these predictive metrics at each site and across sites. Results show that modeling salt marsh soil characteristics with morphometric inputs works best in marshes with simple, single creek morphologies. Distance from tidal creeks was the most significant model predictor. Addition of distance to the inlet and tidal range as regional metrics significantly improves cross-site modeling. Our process-based approach results in predicted total marsh carbon stocks comparable to previous studies but provides trade-offs to existing simplistic carbon mapping methods. Further, we provide motivation to continue rigorous mapping of soil carbon at fine spatial resolutions and to use these results to guide salt marsh restoration projects and aid in the development of carbon markets.
