EVALUATING REFORESTATION OPTIONS FOR SURFACE MINES IN APPALACHIA

Frederick, Joseph 01 January 2019 (has links)
During the last century coal extraction has degraded ecosystems in Appalachia, converting forested land into other cover types that have a diminished capacity to naturally progress to later stages of succession. This projects objective was to examine two options for land-use that can assist in returning the reclaimed surface mines to forested cover types, with increased ecosystem services, and a potential for economic gain. This project examined a biomass plantation and an American chestnut trial. In the biomass trial, greatest heights for American sycamore (12.3 m) and black locust (8.0 m) were found in the fertilizer plots. Mean individual tree biomass for American sycamore and black locust was 6.4 Kg and 5.3 Kg, respectively; no significant differences were found among treatments. In the American chestnut trial, experimental wide survival was 47.2% in 2009, dropping to 24.74% in 2017. No significant differences were found by genotype, stock type, or the interaction in 2017. Use of mined land for woody biomass plantations and locales for chestnut restoration shows potential if proper management techniques are followed. Given the vast amounts of land disrupted by mining activities in Appalachia, approaches such as these deserve further attention and additional research.

How do we get everybody at the table? Enhancing diversity in multi-stakeholder processes for landscape restoration.

Hoekstra, Ilse, Abalzati, Valentina, Lanham, Amanda, Carramashi-Gabriel, Paula January 2022 (has links)
Global ecosystem degradation challenging ecological and social thresholds demands urgent responses that address systemically the complex interrelationships between humans and nature. To improve the adaptive capacity of the social systems and strengthen its resilience to respond to external challenges affecting landscapes, multi-stakeholder approaches for landscape restoration involving diverse actors expressing different perspectives are important. While historically absent groups are recognised as the actors that, when meaningfully engaged, achieve transformational change, the literature is unclear on how this is achieved.This research aims to better understand the particular elements that enhance and limit the ability to establish a diverse range of participants within multi-stakeholder processes for landscape restoration. Using semi-structured interviews with practitioners with relevant experience in engaging historically absent groups, we found that including diversity is an iterative process of forming a microcosm as a complex, adaptive system representing the wider landscape through building on synergies and filling the gaps. A wide range of specific strategies exist to address concrete and structural obstacles hindering participation. Moreover, the specific role of the facilitator, their intangible skills that allow them to be capable of self- awareness, deep reflection and listening, are a key leverage point to navigate the complexity around many systemic obstacles preventing actors on the edge of systems from participating.

Flowing Together: Addressing Social-Ecological Scale Mismatches for Estuary Watershed Restoration in the Whidbey Basin, Puget Sound, WA

January 2015 (has links)
abstract: Landscape restoration is a global priority as evidenced by the United Nations’ 2020 goal to restore 150 million hectares of land worldwide. Restoration is particularly needed in estuaries and their watersheds as society depends on these environments for numerous benefits. Estuary restoration is often undermined by social-ecological scale mismatch, the incongruence between governing units and the bio-physical resources they seek to govern. Despite growing recognition of this fact, few empirical studies focus on scale mismatches in environmental restoration work. Using a sub-basin of Puget Sound, Washington, U.S.A., I analyze scale mismatches in estuary restoration. I take a network science approach because governance networks can bridge scale mismatches. I combine quantitative social network analysis (SNA), geographic information systems (GIS), and qualitative interview analysis. Spatial network analysis reveals several areas with weak scale mismatch bridging networks. These weak social networks are then compared to ecological restoration needs to identify coupled social-ecological restoration concerns. Subsequent study investigates jurisdictional and sectoral network integration because governance siloes contribute to scale mismatch. While the network is fairly well integrated, several sectors do not interact or interact very little. An analysis of collaboration reasons disentangles the idea of generic collaboration. Among three relationship types considered, mandated relationships contribute almost 5.5 times less to perceived collaboration productivity than shared interest relationships, highlighting the benefits of true collaborations in watershed governance. Lastly, the effects of scale mismatch on individual restoration projects and landscape level restoration planning are assessed through qualitative interview analysis. Results illustrate why human-environment processes should be included in landscape restoration planning. Social factors are not considered as constraints to restoration but rather part of the very landscape fabric to be restored. Scale mismatch is conceptualized as a complex social-ecological landscape pattern that affects the flow of financial, human, and natural capital across the landscape. This represents a new way of thinking about scale mismatch and landscape restoration in complex multi-level governance systems. In addition, the maps, network diagnostics, and narratives in this dissertation can help practitioners in Puget Sound and provide proofs of concepts that can be replicated elsewhere for restoration and broader conservation sciences. / Dissertation/Thesis / Doctoral Dissertation Geography 2015

Business models for sustainable investments in the context of tropical forest restoration

Borgersen, Anna January 2017 (has links)
The Tropics continue to provide the most biologically diverse and carbon rich forest in the world, but they are being lost at alarming rates. To meet the global climate change targets and the UN sustainable development goals, financing is urgently needed to speed up and increase tropical forest restoration. The aim of this thesis is to show that sustainable timber and non-timber forest products offer are a viable vehicle for investment in tropical forest restoration and to identify the needed incentives and tools to enable sustainable investment.   There is a lack of research on the integration between business model design and sustainability generally and an absence of business models for tropical forest restoration. Very little research if any, has been undertaken to link the two and evaluate the feasibility of applying business models on tropical forest restoration, especially with regard to its potential as an interesting investment option. This thesis gives a background about tropical forest restorations, sustainable investment, presents three tropical reforestation projects and a conceptual framework. The conceptual framework will be used to evaluate the potential for business model application to finance restoration and enable sustainable investments.   Using a business model for tropical forest restoration projects, which in most cases are not defined as businesses, is an innovative approach and an agent of needed radical change. A business model is a crucial strategic management tool to enable success of tropical forest restorations. The core logic of the business model can offer equitable customer value and the fulfillment of new types of needs. Merging economic development and forest restoration is a powerful tool for innovation. The critical variables for financing are management, monitoring, operational efficiency, political incentives and regulations, stakeholder involvement, community benefits, transparency and information communication technology.

Illuminating Capacity-Building Strategies for Landscape-Scale Collaborative Forest Management Through Constructivist Grounded Theory

DuPraw, Marcelle Elise 01 January 2014 (has links)
This dissertation uses the constructivist grounded theory methods of Charmaz (2011) to explore: 1) the unique characteristics of landscape-scale collaboration; 2) implications for collaborative capacity-building strategies; and 3) the relationship between conflict, landscape-scale collaboration, and conflict resolution. The study was conducted through the US Forest Service's Collaborative Forest Landscape Restoration Program (CFLRP). In the 1980s and 1990s, national forest management conflicts brought the forest industry to a standstill, with many jobs lost. In addition, historic fire suppression practices have made our national forests highly vulnerable to catastrophic wildfire. Many have strong opinions about what should be done and how. The proposed substantive theory suggests landscape-scale collaboration can serve as a conflict prevention, problem solving, or conflict resolution venue and offer opportunities for remarkable efficiencies in forest restoration as well as profoundly restorative transformation in ecological, social, economic, personal, and spiritual dimensions. It identifies unique characteristics of collaboration at this scale; suggests that realizing benefits depends on collaborative capacities at the collaborator, constituent organization, collaborative stakeholder group, and sponsoring organization levels, and on mastering nine challenges; and suggests eight implications for collaborative capacity building strategies. The study contributes to forest restoration, reduced loss of life and livelihood, and economic recovery by contributing to CFLRP effectiveness. It contributes to the field of conflict resolution by: illuminating the collaboration / conflict resolution relationship; a particular application of collaboration; related sources of conflict; and conflict resolution strategies. It advances new directions of study for conflict resolution scholars--i.e., how to help agencies and groups strengthen their collaborative capacities.

Renewing Athens : the ideology of the past in Roman Greece

McHugh, Sarah January 2017 (has links)
In this thesis we explore the period of renewal that Athens experienced during the second century AD. This century saw Athens at the peak of her cultural prominence in the Roman Empire: the city was the centre of the League of the Panhellenion and hosted a vibrant sophistic scene that attracted orators from across the Greek world, developments which were ideologically fuelled by contemporary conceptions of Classical Athens. While this Athenian 'golden age' is a standard feature of scholarship on Greek culture under Rome, my thesis delves further to explore the renewal of the urban and rural landscapes at this time and the relationship between that process and constructions of Athenian identity. We approach the renewal of second-century Athens through four lenses: past and present in the Ilissos area; the rhetoric of the Panhellenion; elite conflict and competition; and the character of the Attic countryside. My central conclusions are as follows: 1. The renewal of Athens was effected chiefly by Hadrian and the Athenian elite and was modelled on an ideal Athenian past, strategically manipulated to suit present purpose; the attractions of the fifth-century golden age for this programme of renewal meant that politically contentious history of radical democracy and aggressive imperialism had to be safely rewritten. 2. Athens and Attica retained their uniquely integrated character in the second century. Rural Attica was the subject of a powerful sacro-idyllic ideology and played a vital role in concepts of Athenian identity, while simultaneously serving as a functional landscape of production and inhabitation. 3. The true socio-economic importance of the Attic countryside as a settled and productive landscape should be investigated without unduly privileging the limited evidence from survey, and by combining all available sources, both literary and documentary, with attention to their content, cultural context and ideological relevance.

Impacts of landscape restoration on the environment and farmers' livelihood in Hita-Borkena watershed, northeastern Ethiopia

Alemayehu Assefa Ayele 10 1900 (has links)
Land degradation has been a global agenda. It has been affecting both developed and developing nations (including Ethiopia). The overall objective of the study was to assess the impact of landscape restoration (including area closure) on the environment and farmers‘ livelihood in Hita-Borkena watershed, northeastern Ethiopia. Three Landsat images (1986, 2001 and 2015) were used to detect land cover dynamics. Laboratory analysis of selected soil physico-chemical properties were made to compare the soil properties of closed/restored and open grazing areas. Household questionnaire was administered to investigate environmental problems before and after landscape restoration, the role of area closure and different conservation measures, and the impact of the restoration on farmers‘ livelihood. A total of 255 household heads were selected randomly for the questionnaire survey. This survey was also substantiated by interviewing agricultural experts, observation and reviewing reports prepared by Kalu District Agriculture Office. Both descriptive and inferential statistics were employed to analyze quantitative data. Besides, qualitative approach was implemented in order to analyze qualitative data. The study found out that forestlands and shrublands shrunk through 1986 – 2015, grasslands expanded mainly due to the implementation of area closure under MERET project since 2001. The study revealed that better organic matter, total nitrogen, clay and silt contents, CEC and total porosity were recorded under area closure than under open grazing land. However, both available P and K were found minimum under the former land use type. This may be due to the reason that such nutrients exist more in unavailable form or it may be because of the fact that large amount of those nutrients are extracted by the restored vegetation. The study showed that rates of soil erosion, overgrazing and illegal cutting of trees were relatively higher before landscape restoration. The respondents also appreciated the positive role of land restoration in improving the fertility of the soils of the study watershed and then the positive impact to their livelihood. Based on the results of the study, it is recommended that similar restoration activities shall be implemented in similar environments in Ethiopia to improve both the environment and farmers‘ livelihood / Geography / Ph.
