The viability of legalising international trade in Rhino horn and the possible effect on Rhino poaching in South Africa

De Beer, Willem 02 1900 (has links)
The existence of the rhino is under serious threat. South Africa has experienced a dramatic increase in rhino poaching since 2008. With the current trend of poaching, rhino in South Africa will soon become extinct. The current strategies to protect rhino have proved to be ineffective. The common view is that rhino poaching is morally wrong, and associated with greed and evil intentions and that rhino poaching must be stopped; however, there are two schools of thought regarding two main approaches (in association with current strategies) to be used in order to stop or limit poaching. The first school of thought supports the CITES ban on international trade in rhino horn, and believes that rhino poaching can only be stopped by eliminating demand (the “conventional approach”). The second school of thought is in favour of the legalisation of international trade, and argues that any solutions to the rhino poaching problem must address the underlying economic forces. This is called the sustainable approach. The research aimed to investigate the effectiveness of the ban on international trade in rhino horn, as well as the viability of legalising international trade. The effectiveness of the current strategies was also investigated. A qualitative research design was used, and eighteen participants were selected in order to obtain information by means of semi-structured interviews and questionnaires.The first school of thought supports the CITES ban on international trade in rhino horn, and believes that rhino poaching can only be stopped by eliminating demand (the “conventional approach”).

A literature review was also conducted, for the purpose of evaluating the responses of participants, and also for the purpose of validity and reliability. The findings indicated that the scales tip in favor of a well-managed, legalized trade, inter alia, to make funds available to rhino owners, rhino custodians and the government, on the one hand, and, on the other hand, to reduce the reward and increase the risk to the poacher. Findings also indicated that a legalized trade cannot be implemented in isolation; it goes hand in hand with increased security and improved law enforcement, while strategies such as dehorning and translocation still have a role to play. Finally, findings also indicated that communities need to be involved in the sustainable use approach. These communities are currently excluded from the benefits derived from the neighboring protected areas, thereby making them susceptible to being recruited as poachers. / Environmental Sciences / Ph.

The illegal trade in endangered animals in KwaZulu-Natal, with an emphasis on rhino poaching

Griffiths, Megan Laura 02 1900 (has links)
The illegal trade in endangered animals in KwaZulu-Natal, with an emphasis on rhino poaching, is tactically addressed in this dissertation. The aim is to expose the nature and extent of these crimes; the victims, offenders and modus operandi involved; the adjudication of wildlife offences; the causes and consequences concerned; the relevant criminological theories to explain these crimes; and recommendations for prevention. This research intends to examine the contemporary pandemic of rhino poaching in KwaZulu-Natal, South Africa, and offer potential techniques for intervention. Furthermore, one of the main goals of the study is to reveal and enhance the extremely neglected field of conservation criminology. A general disregard by society for the environment, as well as the overall ineffectiveness and corruption of criminal justice and conservation authorities, comes to the fore. The purpose of the research is therefore to suggest possible prevention strategies in order to protect the rights of endangered species. / Criminology and Security Science / M.A. (Criminology)

Le braconnage dans le Parc national de l'île de La Réunion

Cloutier-Cyr, Simon 11 1900 (has links)
La faune et la flore de l’île de La Réunion atteignent un niveau d’endémisme très élevé avec le tiers de sa surface encore recouverte par des forêts naturelles. Ces conditions exceptionnelles ont favorisé, en 2007, la création du Parc National de La Réunion qui couvre 40 % du territoire. Parmi les différentes atteintes à l’environnement dans les aires du Parc national, le braconnage est devenu, au cours des deux dernières décennies, un phénomène très préoccupant pour les différents acteurs locaux et régionaux qui s’occupent de la gestion de ce problème. Plusieurs espèces braconnées sont actuellement menacées et les dégâts occasionnés par les braconniers sont visibles dans le paysage réunionnais. Ce projet de recherche vise à répondre à la question de recherche suivante : De quelle façon se manifeste le braconnage (les motivations, la fréquence, les techniques, les lieux) dans le Parc national de La Réunion et comment les différents acteurs réagissent-ils face à la pratique du braconnage? La méthodologie de cette recherche repose sur une démarche combinant l’approche exploratoire et l’étude de cas. Les données qualitatives et quantitatives que nous avons utilisées pour cette étude ont été collectées par une recherche bibliographique, une collection de données statistiques, et par des entrevues (exploratoires, semi-dirigées, individuelles non-structurées) réalisées sur le terrain. Les résultats obtenus nous ont permis de constater que le braconnage à La Réunion est un phénomène ancré dans la culture locale et une conséquence directe du contexte économique actuel. Notre recherche a relevé deux catégories de braconniers : les braconniers occasionnels (touristes et braconniers du dimanche) et les braconniers professionnels. Le braconnage de type occasionnel est très largement répandu dans la population, car il s’inscrit dans une continuité des traditions. Le braconnage de type professionnel où le braconnier prélève de façon systématique dans la nature à des fins monétaires, est pratiqué par peu de gens, mais il occasionne de lourdes pertes contrairement au braconnage de type occasionnel. Les différentes méthodes mises en place par les divers acteurs impliqués dans la gestion du braconnage ont été répertoriées et examinées. Tandis que le poinçonnage des plants de vanille et le marquage des tangues sont efficaces, la délation des braconniers et les visites éducatives restent des pistes à explorer, et les conférences rééducatives des braconniers ainsi que la vente de permis de chasse au tangue ont démontré une faible efficacité. Des recommandations pour améliorer la dynamique entre les acteurs impliqués dans la gestion du braconnage ont été données par plusieurs de ces acteurs interrogés au cours de cette recherche. / Wildlife and flora of Reunion Island is characterized by a high level of endemism. The surface covered by forests accounts for almost one-third of the island. Theses exceptional conditions explain the creation of the “Parc national de La Réunion”. In protected areas of the national park, poaching is becoming a major concern for local and regional actors. As a matter of fact, many poached species are threatened and the damages caused by the poachers are visible throughout the Reunion landscape. The purpose of this research is to answer a major question: How does poaching take place (motivations, frequency, techniques, and places) in the “Parc national” and what are the reactions of the various actors? The methodology chosen in this study combines an exploratory approach and a case study analysis. A field research was carried out and data were collected by a literature search, interviews (exploratory, semi-structured, individual not structured) as well as by a literary analysis. The results of this study show that poaching is a firmly rooted tradition in the Reunion culture and a consequence of the economic context. Our analysis has identified two major categories of poachers: occasional poachers and professional poachers. Occasional poaching is widespread in the population because this activity is bound to traditions. Professional poaching, which refers to a systematic withdrawal of natural resources for money considerations, is the business of a small number of poachers. The damages caused by professional poachers are however more important than those linked to occasional poaching. In this analysis, we have enumerated and examined the methods used by the different actors associated with poaching. Punching vanilla plants and marking tangues are methods which have proven their efficiency. Other methods such as denouncement and educational visits will have to be further explored. However, re-educational meetings for the poachers as well as the sale of hunting licenses are currently not considered effective. During this research, we also have collected recommendations in order to improve the dynamics between the different actors involved in the poaching issue.

An evaluation of the impact of Kruger National Park's development programme on the Hlanganani community in Limpopo

Shikolokolo, Hasani Patrick January 2010 (has links)
M Sc (Botany) --University of Limpopo, 2010 / The Kruger National Park is a world renowned organization and is rated as one of the best nature reserves in nature conservation in the world. Despite all the efforts made to control and protect nature in the Park, there is a need for the involvement of the community around the Park. Community-based conservation in particular has been subjected to a series of scathing criticisms, and it has become increasingly acceptable to advocate a return to more coercive forms of conservation. The establishment of the Park forum consisting of the neighbouring communities and the Park requires new strategies for better integration of conservation and rural development. The interest of conservation can be threatened by various factors, mainly poverty, poaching and wildlife conflicts. The interests of the population residing in the immediate neighbourhood of Kruger National Park can be threatened by proposed wildlife management options, other neighbouring conservation areas, and new tourist development activities. Effective conflict prevention mechanisms need to be developed together with the communities and especially in the implementation process. The study presents a critical analysis of the impact of the development made by the Park to the local communities. The available policies need to be implemented in order to assess their developmental impact they are making on the communities. The community has developed a negative attitude towards the park because they think the park is not doing enough in terms of development and training and skills development. The issue of a budget is a concern because it is not clear whether the park has a budget or not for the community. In as far as the community is concerned, there is no budget available and in as far as the park is concerned, the budget is available for community development. There is no cooperation between the park and the community. It seems the park is operating parallel to the community. There are a lot of uncertainties on the side of the community which has developed into mistrust. Communities like Makuleke are involved in farming such that some of the community members have got some subsistence farming skills. If training may be given to these people, most of them may begin to engage in commercial farming. There is also a strong feeling that the Hlanganani forum which represents the community is not recognized by the KNP management. It is there to fulfill the requirement of the policy. It became clearly that Kruger National Park does not involve the forum which has been formed to function as a link between the Park and the community. The negotiated partnership between the park and the community in terms of nature conservation is now at stake. The community is now more concerned about their safety and that of their livestock because of the wild animals roaming around day and night. This is a very serious problem which exists between the park and the community which in a way may hamper the progress in terms of sustaining the relationship 5 currently being nurtured. It is recommended that the park management as the main active role player should put in place a good, viable and effective communication strategy which will form the basis of communication between the park and the community. This will assist both the park and the community to communicate the available developmental policies to the community. And if that is well communicated it is going to eliminate unnecessary conflict in terms of not knowing what the park has for the community and the policies available to address such developmental issues. / N/A

Enhancing Anti-Poaching Efforts Through Predictive Analysis Of Animal Movements And Dynamic Environmental Factors

Castelli, Elena January 2023 (has links)
This degree project addresses poaching challenges by employing predictive analysis of animal movements and their correlation with the dynamic environment using a machine learning approach. The goal is to provide accurate predictions of animal movements, enabling rangers to intercept potential threats and safeguard wildlife from snares. A wide analysis considers previous studies on animal movements and both animal and environment data availability. To efficiently represent the dynamic environment and correlate it with animal movement data, accurate matching of environment variables to each animal measurement is crucial. We selected multiple environment datasets to capture a sufficient amount ofenvironmental properties. Due to practical constraints, daily representation of the environment is not achievable, and weekly mean or monthly mode values are used instead. Data insights are obtained through the training of a regression neural network using the filtered environmental and animal movement data. The results highlight the significant role ofenvironmental features in predicting animal movements, emphasizing their importance for accurate predictions. Despite some offset and few erroneous predictions, a strong similarity between animal predicted trajectory and animal true trajectory was achieved, indicating that the model is capable to capture general patterns and to correctly tune in predictions of detailed movements as well. The overall offset of the trajectories is still a weak point of this model, but it may just indicate the presence of some underlying systematic error that can be corrected through further work. The integration of such a developed prediction model into existing frameworks could assist law enforcingauthorities in preventing poaching activities.

Do Adult Romantic Attachment Empathy and Social Skills Influence Mate Poaching Infidelity?.

Gorniewicz, James Stephen 07 May 2011 (has links) (PDF)
The present study examined the possibility that adult romantic attachment orientation, empathy, and social skills could either individually or jointly influence the expression of mate poaching behaviors. Participants (N = 404) were recruited from a Southern Appalachian university and ranged in age from 18-60 years, with a mean of 21. Data were collected using a web-based survey system. Results of this study lend support to the growing literature demonstrating a link between adult romantic attachment and mate poaching. Additionally, the present study also added to the literature by showing for the first time 1) a relationship between empathy and mate poaching and 2) a relationship between social skills and mate poaching. Contrary to one of the hypothesized structural models, adult attachment was not found to mediate the relationships between 1) empathy and mate poaching and 2) social skills and mate poaching.

Natural history of the pichi (Zaedyus pichiy) in Mendoza Province, Argentina

Superina, Mariella 15 December 2007 (has links)
The pichi Zaedyus pichiy (Xenarthra, Dasypodidae) is a poorly known, diurnal armadillo inhabiting arid and semi-arid regions of Argentina and Chile that has endured substantial population declines. My objective was to elucidate different aspects of the natural history of Z. pichiy as a first step towards establishing a conservation plan. Wild and captive pichis were studied. Body temperature of wild pichis averaged 35.2±1.2 °C and was highly variable (range 32.2 – 38.3 °C). Temperature measurements of semi-captive males showed that pichis can survive energetically challenging periods by entering hibernation or daily torpor. Stomach contents of poached animals revealed that pichis feed predominantly on insects but also ingest plant material, vertebrates and arachnids. This opportunistic, omnivorous feeding strategy allows them to thrive where food type and availability vary seasonally. The reproductive cycle of pichis was studied by means of histological and fecal hormone analyses. Pichis are seasonal breeders that produce one yearly litter of 1 to 2 offspring, and the initiator of breeding season seems to be an increase in daylength. The absence of regular estrous cycles and corpora lutea in non-pregnant females, and immediate mating attempts after pairing, all suggest that pichis are induced ovulators. Clinical examinations and hematological, serological and coproparasitological analyses of free-ranging pichis, and necropsies and histological examinations of confiscated pichis and roadkills, indicate that the populations are currently in good health. While parasites were often found, no severe pathologies were observed. Infections with potentially zoonotic diseases were rare: only a few pichis were seropositive for Trypanosoma cruzi, none had antibodies against Toxoplasma gondii, and none of the histologically examined individuals presented lesions attributable to these pathogens. Elevated ambient humidity levels often caused moist dermatitis with epidermal detachment in captive pichis. Poaching is currently considered to have a much higher negative impact on the wild populations than disease epidemics. Mortality due to heavy poaching activity may be difficult, if not impossible, to compensate by the current birth rates. This preliminary database on the natural history and reproduction of pichis will assist efforts to conserve this little-known species of armadillo.
