An economic analysis of the 2007 SCB conferenceWait, Requier January 2010 (has links)
The Society for Conservation Biology held their 21st annual conference in Port Elizabeth during July 2007. This was the first SCB conference hosted on the African continent. Over 1500 conservation professionals and students from throughout the world were brought together by the SCB annual meeting. The local organizing committee was interested in the economic impacts associated with the conference and approached the NMMU Economics Department to conduct an economic impact assessment of the conference. The Economics Department invited the researcher to undertake this study towards obtaining an MCom degree in Economics. The economic impact of conferences stems from two sources, namely: expenditure by delegates (the demand-side) and the expenditure by conference organizers (the supply-side). The study focused on the economic impacts of the conference for the Eastern Cape. The conference expenditure produced an increase in demand in the Eastern Cape. Only new expenditure originating from outside the Eastern Cape were considered. An increase in the demand for one industry’s output will create additional demand for the outputs of its supplying industries, because industries are connected through forward and backward linkages. These inter-industry linkages produce a multiplier effect. The initial direct conference expenditure created secondary impacts. The latter were indirect and induced expenditures. In addition to secondary impacts, the SCB conference produced spill-over impacts. The spill-over impacts of the conference were noted (but not quantified). The expenditure by delegates was determined by means of a delegate expenditure questionnaire conducted during the conference. The expenditure by the conference organizers was determined in consultation with the organizers, using their financial statements. The multiplier impacts were estimated by means of an input-output (IO) analysis, using a Social Accounting Matrix (SAM) of the Eastern Cape as the underlying database. These multipliers (Type 1 and 2 multipliers) were estimated using open and closed multiplier models. It was deduced that the 2007 SCB conference created a significant and positive net economic impact in the Eastern Cape. The total direct cash injection of the conference was R12.141 million. Using a Type 1 multiplier this direct stimulus is estimated to have caused an extra R16.502 million increase in gross output. Using a Type 2 multiplier this direct stimulus was estimated to have caused a R19.884 million increase in gross output. The total cash injection of the conference contributed R6.093 million to GVA in terms of a Type 1 multiplier and a R7.344 million increase in GVA in terms of a Type 2 multiplier. Household incomes in the Eastern Cape were increased by R3.384 million. These results confirm that the hosting of major events and conferences is indeed a tool for promoting regional economic development.

Vegetation and soil characteristics around water points under three land management systems in semi-arid rangelands of the Eastern Cape, South AfricaSimanga, Siyabulela January 2013 (has links)
This study investigated the vegetation and soil characteristics in relation to distance from water points under different land management systems in semi-arid rangelands of South Africa. Six study sites, two each from communal grazing, commercial farming and game reserves were selected. Two watering points were selected in each study site. Two 500 m transects were laid from the selected watering points. Each transect was divided into sub-transects at 25 m, 50m, 100m, 200m, 300m and 500m from water points. A 100 m2 plot was marked in each sub-transect to record grass biomas, species composition, structure and distribution of woody vegetation and physical and chemical soil properties. Data were collected for two seasons 2012/13 (winter and summer). Thirty and 41 grass and woody species respectively were identified in all study areas. The most common and dominating grass species include Cynodon dactylon, Digitaria eriantha, Eragrostis obtusa, Setaria sphacelata and Sporobolus fimbriatus. Cynodon dactylon and S. sphacelata occurred more abundantly (p < 0.05) in the game reserves than in the other land management catergories. All the grass species had similar (p > 0.05) abundance along distance gradient from water points. Grass dry matter (GDM) showed significant differences (p < 0.05) between and within land management systems. However, GDM was not significantly affected by season, location of water point within each farm or reserve and distance along water points. Acacia karoo, Coddia rudis and Ehretia rigida were the most dominant woody species. Tree equivalent (TE) density of all encroaching woody plants combined was significantly (p < 0.05) higher on the communal area (1732 TE ha-1) than the commercial ranches (1136 TE ha-1) and game reserves (857 TE ha-1), but with no marked variations along distance from water points under all the land management systems. The electric conductivity (EC) was significantly (P < 0.01) higher in game reserves than in communal grazing areas and ranches. Soil organic matter percentage showed greatest and lowest values in the game reserves and commercial respectively. Soil pH and bulk density did not vary but soil organic matter (SOM), EC, bulk density and soil compaction were significant different with no increasing or decreasing trends. Soil properties were affected by herbivore pressure and trampling around water points with inconsistence magnitude and direction. In conclusion, grass species composition and GDM did not respond to distance from water points because either grazing gradient was absent or the length of transects was not enough to explain the absence or presence of gradients. High proportion of A. karoo and high densities of seedlings and saplings would seem as very good indicators of the woody vegetation changes in the different land management systems and distance from water points. The soil quality indicators around the water-points showed that livestock and game affected soil parameters.

Money for something? : investigating the effectiveness of biodiversity conservation interventions in the Northern Plains of CambodiaClements, Thomas January 2013 (has links)
Despite substantial investments in biodiversity conservation interventions over the past two decades there is relatively little evidence about whether interventions work, and how they work. Whether an intervention is deemed to “work” depends upon how goals are defined and then measured, which is complex given that different stakeholders have very different expectations for any intervention (including species conservation, habitat protection, human wellbeing or participation goals), and because the process of measuring impacts can involve a simplification of more sophisticated ideals. These questions were investigated for a suite of biodiversity conservation interventions, implemented during 2005-2012 in the Northern Plains landscape of Cambodia. The interventions included the establishment of Protected Areas (PAs), village-level land-use planning, and three different types of Payments for Environmental Services (PES) instituted within the PAs. The PES programmes were (1) direct payments for species protection; (2) community-managed ecotourism linked to wildlife and habitat protection; and (3) payments to keep within land-use plans. The impact evaluation compared the results of each of the interventions with appropriate matched controls, considering both environmental and social impacts between 2005-2011. Both PAs and PES delivered additional environmental outcomes: reducing deforestation rates significantly in comparison with controls and protecting species for those cases where appropriate data was available. PAs increased security of access to land and forest resources for local households, benefiting forest resource users, but restricting households’ ability to expand and diversify their agriculture. PES impacts on household wellbeing were related to the magnitude of the payments provided: the two higher-paying PES programmes had significant positive impacts for participants, whereas a lower-paying programme that targeted biodiversity protection had no detectable effect on livelihoods, despite its positive environmental outcomes. Households that signed up to the higher-paying PES programmes, however, typically needed more capital assets and hence they were less poor and more food secure than other villagers. Therefore, whereas the impacts of PAs on household wellbeing were limited overall and varied between livelihood strategies, the PES programmes had significant positive impacts on livelihoods for those that could afford to participate. This is one of the first evaluations of the social impacts of PES that has been completed globally. The PA authorities were primarily effective at deterring external drivers of biodiversity loss, especially large-scale developments, land grabbing and in-migration, and had much more limited impact on local residents as the impact evaluation results demonstrated. The PES programmes had little or no effect on the external drivers, and instead explicitly targeted the behaviour of local residents. The three PES programmes differed in the extent to which they rewarded changes in individual or collective behaviour, and whether or not they were managed locally or externally. Household-level, conditional, payments were more effective at changing individual behaviour than collective payments; although there was evidence that both types of payments did lead to protection of forests at the village scale. Village-managed PES programmes empowered a subset of households that were then effective at enforcing regulations within the village. Externally managed PES programmes were more popular and viewed as fairer, but did not change collective behaviour. The general conclusion is that the design and institutional arrangements of PES programmes determines how participants perceive the programmes, and then the extent to which they bring about changes in behaviour.

Impact of naturalness-promoting beech forest management on the forest structure and the diversity of breeding birdsBegehold, Heike 13 January 2017 (has links)
Currently, existing European beech forests (Fagus sylvatica L.) are scarce and fragmented across vast parts of their potentially natural distribution. About 25 % of the global range of beech forests is located in Germany. Thus, Germany has a particular responsibility to integrate biodiversity conservation aspects into beech forest use. In this thesis, the influence of naturalness-promoting management on forest structure and breeding birds was investigated – in comparison to management without a biodiversity focus (different management) and forests sites that have been unmanaged for different periods of time (recently: unmanaged for 14-32 years as of 2012, and long-term: unmanaged for 65 years or since at least 1900). With a total area of 714 ha, 22 study sites located in the northeastern part of Germany were studied. Forest structure was studied using forest development phases (FDPs), which divide the forest life cycle into different periods. FDPs are characterized by a defined combination of five structural parameters such as canopy cover, diameter at breast height, tree height, regeneration cover and deadwood amount. FDPs were mapped during the winters of 2012 and 2013 according to a dichotomic decision tree. Breeding bird abundances were determined in 19 study sites and each study site was mapped 10 times between March and July of the same years using a territory mapping method. FDP patterns such as proportions, patch sizes, distances between patches of the same FDP, evenness, FDP transition within a decade and transition diversity, as well as bird abundances and development of bird densities within a decade were analyzed.
Study sites under naturalness-promoting management differ clearly from differently managed sites and they are comparable or develop similarly to (long-term) unmanaged stands regarding FDP patterns. This also applies for the composition of the breeding bird community and the development of breeding bird species within a decade. The effect of naturalness-promoting management within the last decade is strong as evidenced by: significant decreases in FDP patches in size, the development of FDP richness towards a complete set; the comparability of transition proportion and transition diversity with long-term unmanaged sites (for former gaps, regeneration phase, early-, mid- and late optimum phase as well as disintegration phase); the higher total abundances of all breeding birds as compared with differently managed and recently unmanaged sites; and the highest number of increasing bird species amongst all management types. Further, the occurrence of breeding birds is linked to FDPs. On the one hand, the breeding bird community has a strong preference for FDPs of later-stages such as the terminal and disintegration phases. On the other hand, every bird species has its own set of preferred and avoided FDPs and every FDP has several bird species preferring it. Thus, a complete set of all FDPs at small scale is necessary for the habitat requirements of birds inhabiting beech forests.
In conclusion, 1) the positive impact of naturalness-promoting management on forest biodiversity is already detectable after a decade and 2) FDPs are a suitable indicator can be used as an innovative indicator for monitoring the impact of forest management on biodiversity.

Réconciliation des enjeux de la conservation de la biodiversité et de développement : Analyse des perceptions de la mise en place d’une aire protégée dans la forêt du Karthala aux Comores / Reconciliation biodiversity conservation and development goals : Analysis of the perceptions of the creation of a protected area in the Karthala forest in ComorosSoilihi, Abdou 08 November 2018 (has links)
Résumé : À l’heure où on vit la 6ème crise de la biodiversité, tous les pays signataires de la Convention sur la diversité biologique s’engagent à mettre en place des outils pour préserver leur patrimoine naturel. Les aires protégées représentent un des outils privilégiés pour la conservation de la biodiversité. Elles peuvent avoir des effets positifs et négatifs sur les populations riveraines ; parfois elles sont une source de conflits entre ces populations et les gestionnaires. Cette thèse de doctorat propose une approche interdisciplinaire pour analyser comment la réconciliation des enjeux de conservation de la biodiversité et de développement, dans et autour de la forêt du Karthala aux Comores, peut être appréhendée à partir des perceptions et des expériences des acteurs. Elle vise plus précisément à répondre à la question suivante : comment la notion d’aire protégée, qui est un concept occidental porté par des acteurs institutionnels internationaux aux Comores, entre ou non en conflit avec les perceptions des acteurs des territoires concernés ? Plusieurs méthodes complémentaires ont été utilisées. Nous mettons d’abord en lumière les représentations des composantes de la forêt et les perceptions des différents acteurs sur le projet de mise en protection. Ces perceptions sont comparées et discutées pour évaluer leur pertinence dans la prise de décisions conciliant objectifs de conservation et de développement du territoire. Nous avons ensuite mis en évidence la caractérisation des expériences de nature des riverains en explorant la relation humain-nature. Enfin, nous proposons une analyse intégrée des relation humains-forêt et du système socio-écologique qu’il représente à travers les représentations des riverains, les expériences de nature, l’importance déclarée de l’utilisation des ressources et l’identité environnementale. Toutes ces approches relativement nouvelles dans les pays du Sud permettent une discussion approfondie et importante pour discuter le processus de mise en place du Parc national du Karthala. / At the time of the 6th biodiversity crisis, all signatory countries of the Convention on Biological Diversity are committed to adopt tools allowing the preservation of their natural heritage. Protected areas are one of these tools for biodiversity conservation. These tools can have positive and negative effects on local populations; sometimes they are a source of conflict between these populations and managers. In this PhD thesis, we proposed an interdisciplinary approach to analyze how is it possible to reconcile biodiversity conservation goals and development issues in and around the Karthala forest in the Comoros. More precisely, we addressed the following question: How does the notion of protected area, which is a Western concept developed by international institutional actors, is in conflict or not with the perceptions of the actors of the territories concerned (here the Karthala forest)? We used several complementary methods for developing our analysis. We first analyzed the representations of the stakeholders regarding the Karthala forest as well as the perceptions of the project of creation of the park. These perceptions are therefore compared and discussed to to understand better if they can be a support for reconciling conservation and development objectives. We then point out the characterization of nature experiences by exploring the human-nature relationship. Finally, we propose an integrative analysis of the human-forest relationship and describe the corresponding socio-ecological system from local residents representations, experiences of nature, weights of the resources for local uses and environmental identity. These works allow for an in-depth discussion in the decision making process and the governance of the Karthala National Park.

Sustainable protected areas: Synergies between biodiversity conservation and socioeconomic developmentGatiso, Tsegaye T., Kulik, Lars, Bachmann, Mona, Bonn, Aletta, Bösch, Lukas, Freytag, Andreas, Heurich, Marco, Wesche, Karsten, Winter, Marten, Ordaz-Németh, Isabel, Sop, Tenekwetche, Kühl, Hjalmar S. 09 November 2023 (has links)
1. Reconciling conservation and socioeconomic development goals is key to sus-
tainability but remains a source of fierce debate. Protected areas (PAs) are be-
lieved to play an essential role in achieving these seemingly conflicting goals.
Yet, there is limited evidence as to whether PAs are actually achieving the two
goals simultaneously.
2. Here, we investigate when and to what extent synergies or trade- offs between
biodiversity conservation and local socioeconomic development occur. To ex-
plore these relationships, we collected data across a wide range of socioeco-
nomic settings through face-to-face survey with PA managers from 114 African
and European PAs using structured questionnaire.
3. We found synergies between biodiversity conservation and socioeconomic
development for 62% of the PAs, albeit with significant differences between
African (55%) and European PAs (75%). Moreover, the sustainability of PAs in
conserving biodiversity was strongly correlated with the empowerment of the
PA management and the involvement of local communities in PA planning and
decision-making processes.
4. Our results demonstrate that for PAs to promote synergies between biodiver-
sity conservation and local socioeconomic development, and to enhance their
long-term sustainability, they should invest in the empowerment of their respec-
tive management and involvement of local communities in their planning and
management activities

Image Based Oak Species Classification Using Deep Learning ApproachShiferaw, Adisalem Hadush, Keklik, Alican January 2024 (has links)
Real-time, minimal human intervention, and scalable classification of oak species, specifically Quercus petraea and Quercus robur, are crucial for forest management, biodiversity conservation, and ecological monitoring. Traditional methods are labor-intensive and costly, motivating the exploration of automated solutions. This study addresses the research problem of developing an efficient and scalable classification system using deep learning techniques. We developed a Convolutional Neural Network (CNN) from scratch and enhanced its performance with segmentation, fusion, and data augmentation techniques. Using a dataset of 649 oak leaf images, our model achieved a classification accuracy of 69.30% with a standard deviation of 2.48% and demonstrated efficient real-time application with an average processing time of 25.53 milliseconds per image. These results demonstrate the potential of deep learning to automate and improve the two oak species identification. This research provides a valuable tool for ecological studies and conservation efforts.

aestheticism of objects.
The different manifestations of ceo-feministic thought within
environmental activism are explored to make the reader aware of the
diversity of ceo-feministic thought. Eco-feminism in general, tries to
promote the importance of the earth as a life supporting system by
respecting her needs, cycles, energies and eco-systems. As a result of
this process, the public are invited to take part in recycle-art through

Enhancing the ecotourist experience at Shongweni Reserve through the use of appropriate interpretive strategiesFoley, Jonathan January 2011 (has links)
Submitted in fulfilment of the requirements of the Degree of Masters of Technology: Tourism and Hospitality, Durban University of Technology, 2011. / The current biodiversity and extinction crisis has ignited global concern for human and planetary well-being, culminating in the declaration by the United Nations of 2010 as the International Year of Biodiversity. Concomitant with these developments has been the steady ascent of the ecotourism industry, a subset of the travel and tourism industry that holds some promise for the conservation and enhancement of natural areas. A third strand that may be added that weaves them all together for mutual benefit, is the use of interpretation as a communication strategy that enhances the travel experience for the visitor, stimulating interest and enriching their knowledge of local natural resources. This study examines the role of interpretation within one of the largest protected areas in the Durban area, Shongweni Reserve. Rich in faunal and floral diversity, the reserve hosts a range of active and passive recreational pursuits for local and international visitors. This study examines the range of natural, historic and cultural resources within the Shongweni Reserve and then develops appropriate themes for interpretive print material to effectively provoke and stimulate visitor interest in local biodiversity. Print samples were attractively designed to showcase interesting facets of plant and animal wildlife in the reserve. The samples integrated aspects of floral and faunal conservation status together with Zulu cultural use in the narrative and text. Findings from the survey revealed that most visitors were interested in learning more about local biodiversity and found the interpretation material to have a high degree of personal relevance. This has significance in terms of encouraging reserve management to communicate effectively with their visitors using interpretive media as a vehicle and stimulus for biodiversity conservation.
