Restoring the Mississippi River Delta in Louisiana Ecological Tradeoffs and Barriers to ActionMaulhardt, Alison 18 December 2015 (has links)
This study investigates the Louisiana 2012 Coastal Master Plan’s ability to reconcile conflicting economic and ecological demands on coastal resources. The Louisiana Coastal Master Plan was unique in combining flood control and coastal restoration under one authority. However, the objectives of flood control and coastal restoration can be in conflict. The plan was also unique in its approach of restoration from a working coast perspective. However, the objectives of ecological restoration and economic productivity do not always agree. By conducting semi-structured interviews with major coastal stakeholders, this research will explore how the planning process has accommodated the views and values of key stakeholder parties. This research aims to make more transparent the inherent environmental tradeoffs of restoration from a working coast perspective. A working coast is a compromise between economic and environmental stakeholder needs. The approach requires a balance of power to ensure that the projects selected best serve the needs of all parties. The study found that while there is industry buy in, mechanisms for mitigating economic externalities is lacking in the plan, corporate infrastructure benefits while wildlife resources are in decline.

Inserção de jogadores virtuais em jogos de papéis para uso em sistemas de apoio à decisão em grupo: um experimento no domínio da gestão de recursos naturais. / Insertion of virtual players in role playing games to use in group decision support systems: an experiment in natural resources management.Adamatti, Diana Francisca 05 June 2007 (has links)
Este trabalho propoe a definicao de uma arquitetura para incorporar jogadores virtuais em uma classe de Sistemas de Apoio a Decisao em Grupos (SADs-G), baseados na utilizacao conjunta de Simulacao Baseada em Multiagentes (MABS) e Jogos de Papeis (RPGs). Estas duas tecnicas, MABS e RPGs, vem sendo utilizadas de forma integrada ha alguns anos devido a capacidade de discussao e aprendizado dos RPG e da capacidade dinamica de MABS. Os jogadores virtuais definidos devem ter a capacidade de tomada de decisao e de comunicacao entre si e com os jogadores reais durante as negociacoes. Os principais aspectos discutidos neste trabalho sao: i) se os jogadores virtuais definidos possuem comportamentos nao-triviais perante aos jogadores reais; ii) se continua ocorrendo o processo de negociacao entre os jogadores, sejam eles reais ou virtuais; iii) se a realizacao de um jogo de forma eletronica (via computador) dificulta a interacao entre os jogadores. De forma a discutir estes aspectos, duas instancias de SADs-G foram implementadas no contexto da Gestao de Recursos Naturais, pois neste dominio o processo de negociacao e extremamente importante e complexo. / This thesis proposes the definition of an architecture to insert virtual players in a particular subclass of Group Decision Support Systems (GDSS), that uses Multi-Agent-Based Simulation (MABS) and Role-Playing Games (RPGs) techniques in an integrated way. These techniques can bring interesting results, since it is possible to join the dynamic capacity of MABS with the discussion and learning capacity of RPGs. The defined virtual players must make decisions and communicate with each other and with the real players during the negotiation process. In this work, the main aspects discussed are the following: i) can virtual players have no-trivial behavior in the face of real players? ii) is the negotiation process between all players (virtual or real) still happening when virtual players are inserted? iii) do electronic games make more difficult the interaction between players? In order to discuss these aspects, two instances of GDSSs were developed in the natural resources management domain. This domain was chosen because its negotiation process is both very important and complex.

Elucidating the Effects of Thiamethoxam Neonicotinoid on Honey Bee Learning Using the Proboscis Extension ResponseShepherd, David J 01 May 2017 (has links)
In this study, the effects of the neonicotinoid pesticide, thiamethoxam, are examined through the Proboscis Extension Response (PER) in honey bees (Apis mellifera). PER is a form of classical conditioning applied to honey bees through scent and reward association which quantifies learning rates. Results between groups treated with thiamethoxam did not differ significantly from untreated control groups. Potential reasons for these results are discussed. The method and experimental apparatus for testing the PER assay are also discussed.

Including Human Population Characteristics in Ecological Niche Models for Aedes aegypti when Modeling Projected Disease Risk due to Climate ChangeObenauer, Julie, Quinn, Megan, Li, Ying, Joyner, Andrew 07 April 2017 (has links)
The Aedes aegypti mosquito is responsible for transmission of four vector-borne diseases that cause considerable global morbidity and mortality. Projections of the future effects of global climate change indicate that expansion of this species due to changing habitats is possible. Furthermore, since A. aegypti is highly dependent on human populations for feeding and egg-laying sites, changing human population characteristics are likely to alter the risk of exposure for humans based on geographic location. This study aims to create future potential risk maps for human exposure to A. aegypti using human population density as a predictor. Using current population density data and future growth trajectories, high-resolution human population density forecasts were created for 2050, then included as variables in ecological niche models developed using Maxent. Species occurrence data and high resolution climate data for current and future conditions (best and worst case scenarios) were included in the model, as well. Model fit indices and variable contributions indicated that the inclusion of human population density improves model accuracy for A. aegypti. Risk maps created by these models showed that areas currently adjacent to large cities within endemic regions, such as central Africa and western Brazil, are likely to see the greatest increase in risk to human populations. This corroborates current projections on increasing urbanization in the future and suggests that these models can be used to target interventions in high risk areas.

Business Drivers for Environmental Regulations Compliance in Ghana's Mining SectorAhorbo, Georgina Angorkor 01 January 2014 (has links)
Ghana's mining sector is a significant contributor to the national economy; however, environmental degradation continues to stigmatize the sector. The purpose of this phenomenological study was to explore experiences and perspectives of middle managers on how to drive compliance with EPA regulations and standards in Ghana's mining sector. Ajzen's theory of planned behavior was the conceptual framework for this phenomenological study. A purposive sample of 20 middle managers from Ghana's mining sector participated in interviews, which were transcribed and then coded to generate common themes. The primary research question involved exploring factors that promote employee compliance in Ghana's mining sector. Three critical themes that emerged from the study were (a) business benefits of compliance, (b) factors that promote employee compliance, and (c) obstacles to compliance. The implications for positive social change include the potential for community members to experience reduced environmentally related health challenges with concomitant increases in their quality of life

Riparian management guides : are they meeting the needs of the interested public?Robertson, M. S. T. January 2008 (has links)
In New Zealand, there are many published guidelines about the management of riparian areas. The question needs to be asked, are these guides useful? This research thesis investigates the extent to which riparian management guides meet the needs of the users. This research also considers the importance of riparian management (with regards to the appropriateness of educational guides) in assisting practitioners and the interested public in the management of riparian areas. The main way of investigating this topic was with the help of discussion groups. Discussion groups were held with interested organisations. These groups fell into three categories; Urban groups, Rural groups and Interest groups. The groups were asked to define what would make a guide most useful and desirable to them under three major categories: 1) what the guide looked like, 2) what information was contained, and 3) how was the information accessed. An opportunity was also provided for any further comments. This information was used to create a list of the most popular criteria that existing guides and further publications could be examined against. Eleven criteria were identified as follows: Information should be available online; Have pictures; Include diagrams; Is simple and easy to understand; Contains how to and appropriate methods; Has a plant list; Considers maintenance issues; Identifies where to locate further information; How to contact experts; Is available in libraries; Is in booklet form. The availability of existing information was investigated and its suitability assessed against the criteria. A list of all regional, territorial and unitary councils as well as 'other organisations' that were regarded as sources of environmental knowledge were investigated to see how many had produced information on riparian and wetland management issues. In terms of sources of information, 'other organisations' produce the greatest rate of riparian management information, followed by regional/unitary authorities. Two guides from Canterbury best meet the criteria identified by the interested parties, for the Canterbury region. Each scored 10/11 and failed on different criteria. This led to the conclusion that riparian management guides in Canterbury, while obviously still having room for improvement, are very close to meeting what interested parties feel is most important. Finally, a prototype (model) based on the research is provided for anyone who might be considering preparing a riparian management guide.

Technology and meaning in natural resource management : the story-making role of GIS in the CLAMS projectDuncan, Sally 17 November 2004 (has links)
The working hypothesis for this study is that the introduction of GIS technology
into the ancient procedures of map-making has changed the map-making context
sufficiently to require a revision of the way we think about, learn from, and use maps,
specifically in the public involvement process in natural resource management. The
assumption that we jointly know what maps mean, and how to use them, has been
carried unchallenged into the vastly changed arena of digital, information-dense, and
highly technical map-making, courtesy of Geographic Information Systems (GIS). It
has remained unchallenged even as the social context for environmental policy-making
is undergoing historic upheaval.
GIS fundamentally changes how information is viewed, literally, by many
different groups, for its maps and databases contain varying levels of uncertainty,
multiple embedded assumptions, potentially privileged knowledge, and considerable
power as story-makers, along with unintended and unexplored social consequences. GIS
maps/databases are used here as the central refractor of ideas about relationships
between scientists and lay audiences; between the post-modern understanding of
privilege and social change; and ultimately between technology and meaning, where
changing expectations about the role of science in natural resource management
resonate most profoundly.
Key research questions are: (1) How can GIS maps contribute to mutual learning
in the natural resource management arena?, and (2) Which consequences of GIS
development could change approaches to natural resource management? The
exploratory case study used to address these questions examines GIS maps from the
Coastal Landscape Analysis and Modeling Study (CLAMS), a landscape-scale
bioregional assessment in western Oregon that draws heavily on GIS technology to
illustrate ecological and socioeconomic dynamics and interactions.
Findings suggest that use of GIS through time may change the realm of
designing and structuring decision problems, adjusting it from a largely science-driven
exercise in natural resource management to a more collaborative story-making one.
While epistemological differences between scientists and lay audiences remain, they
can be offset through such collaboration, with concomitant shifts in power structures
that could affect a range of conditions including rates of technology diffusion, and
management of a broad transition in how natural resources are perceived and utilized. / Graduation date: 2005

Sediment Removal from the San Gabriel MountainsFerguson, Mary C 01 May 2012 (has links)
The issue of sediment removal from the San Gabriel Mountains has been a complex issue that has created problems with beach replenishment, habitat destruction and the need to spend millions of dollars at regular intervals to avoid safety hazards. Most recently 11 acres of riparian habitat, including 179 oaks and 70 sycamores, were removed for sediment placement. Other sites including Hahamongna Watershed Park and La Tuna Canyon also face a similar fate. This thesis questions: How did we get to this point of destroying habitat to dump sediment which is viewed as waste product? What are the barriers for creating long term solutions and progressive change? What are some other options? And how should we move forward? The issues with sediment management have stemmed from regulatory compliance issues, adversarial relationships within agencies and among NGO's and the public, and the lack of a comprehensive long-term plan to prevent further habitat loss and other sediment removal issues. A recommendation includes looking at a community forestry model to include a wide cross-section of the community, NGO's and government agencies to come up with a long term comprehensive and progressive solution.

User attitudes to conservation and management options for the Ongoye Forest Reserve, KwaZulu-Natal, South Africa.Phadima, Lehlohonolo J. January 2005 (has links)
Indigenous forest resources are valuable to communities situated around them as they
provide many different resources for their livelihoods. South Africa has only 0.5% of
indigenous forest cover and most forests are surrounded by local communities who
depend on them for resources. At Ongoye the forest was widely (91% of households)
used for fuelwood. Community members denied harvesting the forest for either building
or fencing poles, claiming they bought Eucalyptus poles from suppliers in the
community. However, the harvesting intensities of pole size stems confirm that the user
community does harvest timber from the forest. There is a high demand for fuelwood and
pole-size stems are harvested not only for building but are cut and left to dry for later use
as fuelwood. Although the harvesting intensity was greater than users were prepared to
admit to, harvesting levels are thought to be sustainable. Local communities did not trade
in products extracted from the forest. The use of resources was only for subsistence
purposes, and therefore, forest resources were only valuable to users with respect to
providing support to local livelihoods.
Ensuring the protection and conservation of forest resources is critical for the survival of
the user communities that are dependent upon them. Most local communities are not
knowledgeable about managing forest resources adjacent to them, and the management of
forest resources at Ongoye is currently in the hands of the state and also the influence of
the Inkosi (local tribal chief). As part of the process of democratization post 1994, the
government is devolving the management of natural resources to local communities.
Several models of management institutions have been proposed and tested including
community forest management (CFM), state forest management (SFM), and participatory
forest management (PFM). Current trends are towards participatory management
institutions. Using questionnaires, I determined that users preferred PFM over both SFM
and CFM. However, the local community was in favour of more state involvement in the
PFM than expected. Given a choice between CFM and SFM, the user community was
more favourably disposed toward SFM. This was because they viewed CFM as
vulnerable to resulting in open access to resources without any control.
The devolution of powers to local communities can create problems in local governance.
For most areas surrounding forest resources, traditional authorities are the important
'governing' leaders. In South Africa, events post 1994 have created tensions between
democratically elected and hereditary governance institutions. On the one hand
democratic institutions are supposed to be created at the local level, and on the other the
constitution recognizes the existence of hereditary institutions. There is a power struggle
over who the legitimate authority at the local level is between democratically elected
councilors and chiefs. At Ongoye, the local chief was very powerful and had strong views
on the ownership and control of Ongoye. He had a positive influence on maintaining
current low to moderate levels of use of forest resources. However, because there are
several dangers associated with concentrating power over management of natural
resources in one individual, I recommend that a participatory natural resources
management institution be developed that acknowledges the important role of the Inkosi,
but also tempers his influence, so that continuity of management principles is maintained
should traditional leadership changes hands. / Thesis (M.Sc.)-University of KwaZulu-Natal, Pietermaritzburg, 2005.
