A critical analysis of the socioeconomic impact assessments of the Addo Elephant National Park

Rose, Matthew Calvin January 2011 (has links)
Impact assessment is a requirement for development in many countries across the globe, seeking to inform the decision-maker as to the environmental, social and economic impact of an ongoing or proposed project. Socioeconomic impact assessment (SEIA) is a means of informing decision-makers as to the socioeconomic effects a project could have, or is having, thus contributing to informing adaptive management practices. However, the tendency of socioeconomic impact assessment to highly quantitative economic methods of analysis raises the question of whether the desired results are achieved by the process. The purpose of the research was to determine whether highly quantitative forms of economic analysis are suitable for measurement of impacts in a social context where distributive as well as net impact is important; to critically analyze the method utilized in achieving highly quantitative economic impact assessment results; and lastly to draw conclusions and make recommendations regarding the efficacy of monitoring processes used to inform adaptive management practices. The research was conducted by means of a case study focusing on three SEIAs carried out on the same entity, namely the Addo Elephant National Park. Managed by South African National Parks (SANP), it began expanding its borders in the early 2000s. Funded by the World Bank, SANP was required to carry out a comprehensive Strategic Environmental Assessment (SEA) in 2003 to ensure the expansion did not have negative environmental, social and economic repercussions, and where such consequences were unavoidable, to ensure that mitigation and management thereof was informed by useful monitoring exercises. Given the need for resettlement and issues of economic distributive concern raised in the 2003 SEA, the three socioeconomic impact assessments conducted from 2005 – 2010 as part of the ongoing monitoring exercises formed an ideal framework for answering the primary research questions. The findings indicate that despite consistent terms of reference, different assessors interpret mandates from the commissioning body in different ways, leading to varied applications of the same theory, some methodologically better than others. Economic multiplier analysis was found to be inadequate as a measure of the distributive effects of economic impact. Moreover, a lack of consistency, accountability and transparency in the monitoring process led to three sets of results that were incomparable over time and thus inadequate as a means to inform adaptive management practices. Asymmetries of and between power and expertise in the commissioning body and the assessors led to breakdowns of the assessment process in terms of accountability and integrity and resulted in a failure to properly define the scope of the study and measure the relevant indicators. The following recommendations were made: that the economic multiplier method be complemented by additional methods of analysis when utilized in disparate social contexts where distribution of economic benefit is important; that monitoring practices be systematized at an early stage of the process to ensure comparable results useful in informing ongoing management practices; and that what an assessment measures and how it measures it be clarified with reference to an objective source. Finally, the number of factors for consideration in any impact assessment means that measurement of the full picture suffers resource constraints, emphasizing the need for impact assessment oversight to recognize the deficiencies of the process whilst still acknowledging that ‘some number is better than no number’.

Elephant impact on the large tree component and its potential effect on selected fauna

Rode, Sieglinde Corny 10 1900 (has links)
The aim of the study was to determine the consequences of elephant (Loxodonta africana) impact on selected nesting sites of avian fauna and other species in the Associated Private Nature Reserves. The study also aimed at answering key questions on how the architecture of trees influence nest site suitability and what landscape features affect nest site location. Furthermore the type of impact that elephants have on specific nesting sites was determined and how this would affect the short term persistence of these trees. The facillitatory role of elephants was examined by looking at the type of impact that produces gum exudants as well as what gum is selected for by primates and whether primary branch breaking may lead to the creation of nesting sites for species such as the southern ground hornbill (Bucorvus leadbeateri). / Environmental Sciences / M.

Adjusting lion diet estimates to assess lion impacts on small prey in Addo Elephant National Park

Gerber, Amarein Judith January 2017 (has links)
Populations of small prey species (< 92 kg) can be regulated by competition, habitat-mediated responses, climate change, disease and predation. Populations of small prey species have declined in the Addo Elephant National Park Main Camp Section since the reintroduction of apex predators (lion and spotted hyaena). One possible explanation is predation by lion and spotted hyaena. However, small prey species are not generally considered preferred prey items of these predators, hence their contribution to predator diets needs to be explored. Global Positioning System (GPS) cluster analysis has emerged as a viable approach to locate lion kills for lion diet estimation in AENP, however this technique is known to bias diet estimates to large prey species. Understanding the impact of lion predation on populations of small prey in Main Camp therefore requires better estimates of lion diets. This study investigated the potential underestimation of small prey species in lion diet estimates by combining the data from scat analysis and carcasses located at GPS clusters. The adjusted lion diets were then used to investigate if the impact of lion predation could explain declines in small prey, by relating lion prey preferences to prey population trends in Nyathi. Using the results from Nyathi, it could then be inferred whether lions could have been responsible for the declines observed in Main Camp. Six GPS-collared lions provided location data used to construct individual movement paths, along which spatio-temporal clusters of GPS locations (n = 4896) were identified for ground investigation. Carcasses (n = 643) were recorded at the GPS clusters and scats (n = 256) were collected at GPS clusters with or without carcasses. Data from the located carcasses and scat collections were then used to create a history of feeding events for each collared lion in Main Camp-Colchester and Nyathi from a) carcasses alone or b) a combination of scats and carcasses, based on an estimated short and long lion throughout period. Relative prey availability was estimated based on camera trapping in Nyathi in high lion, low lion and no lion use areas, as lions may encounter some prey species more than other prey species. Jacobs’ index prey preference was used to investigate the importance of prey species to lion diets at three landscape scales: 1) Nyathi, 2) lion UD and 3) core lion UD. Lastly, prey population trends were investigated in Nyathi to provide an indication of possible changes in prey populations. Large prey species dominated the adjusted diets of lions in Main Camp-Colchester and Nyathi. However, when comparing the GPS carcass-derived lion diet estimate to the combined lion diet estimate, small prey were underestimated more often than large prey in the GPS carcass-derived lion diet estimate. Missed feeding events were therefore a function of prey body size. In addition, missed feeding events were also representative of the lion diets based on carcasses, with the tendency for species more often consumed to be missed more often in the diet record. However, even though small prey species were underestimated, they represented the minority of species consumed by lions and were predominantly avoided by lions in Nyathi. Lion prey preferences thus did not correlate to the declines in small prey species in Naythi, suggesting other potential drivers are important for small population trends in Nyathi. Lion predation cannot be ruled out as a driver of the decline in small prey species in Main Camp, due to different ecological conditions (e.g. vegetation density) in Main Camp compared to Nyathi, during the observed small prey population declines. Lion prey preferences in Nyathi revealed fine-scale variations in species specific preferences by lions, as well as site-specific differences in prey preferences when compared to published lion prey preference meta-analyses. These findings suggest that metaanalysis studies should be used as a guideline from which hypotheses about local predatorprey interactions can be developed rather than as an absolute measure of prey preference.

A homoeopathic drug proving of the ivory of the male African elephant (Loxodonta africana) with a subsequent comparison to the doctrine of signatures

Speckmeier, Claire Tamryn January 2008 (has links)
Thesis (M.Tech.: Homoeopathy)-Durban University of Technology, 2008. xiv, 222 leaves / A proving of ivory from the male African elephant (Loxodonta africana) 30CH was conducted. The proving symptoms were then analysed according to the doctrine of signatures, and compared to the proving symptoms of Lac Loxodonta africana. Aims and Objectives of the study The aim of this study was to identify the effects of ivory from male African elephant (Loxodonta africana) in a 30CH dilution, on healthy provers, and to record the clearly observable signs and symptoms produced by the provers, so as to determine the material medica of the proven substance. The objective of the study was to analyze the symptoms obtained from the proving according to the doctrine of signatures, and to establish any correlation that may exist between the homoeopathic drug picture produced and this doctrine. Methodology The remedy was derived from the tusk of a male african elephant (Loxodonta africana) and was prepared in accordance to the German Homeopathic Pharmacopoeia (Drishien, 2003:36-38). The remedy was dispensed in the form of six lactose powders. The research was conducted as a randomised, double blind placebo controlled study. A group of provers (26) that were carefully selected from the general public (Appendix A) were divided into two groups. Recruitment commenced by obtaining suitable provers through speaking to fellow homoeopathic students, as ii well as members of the general public. The researchers conducted interviews with potential provers, excluding those that did not meet the inclusion criteria (Appendix A). The provers were randomly divided into two groups, and instructed to begin recording in their journals a week before starting the remedy, and a week after taking the remedy. The provers continued to record all symptoms until the symptoms abated and continued recording after this time for another two weeks. Once the proving had been completed another full case history and physical exam was performed. Results After the results were collaborated the proving symptoms were then analysed according to the doctrine of signatures. The results of this proving indicated that Loxodonta africana has the potential to be a valuable remedy in homoeopathic practice. Proving signs and symptoms revealed that the remedy could be indicated for mental and emotional conditions as well as a variety of physical diseases. The results of this research confirmed the hypothesis that the proving of Loxodonta africana 30CH would produce clear observable signs and symptoms when administered to healthy individuals. The results of this research also confirmed the second hypothesis that a comparison would exist between the proving symptoms and a doctrine of signatures analysis. Conclusion Thus the proving of Loxodonta africana and the subsequent comparison to the doctrine of signatures has the potential to become a well utilised homoeopathic remedy.

BE United

Barber, LaMar 01 May 2016 (has links)
Let's Rap: An Artist Statement It is not enough for me to cite music solely as a source of inspiration. Hip-Hop, R&B, and, particularly, rap music has as much to do with my upbringing as does the public school system. According to Wikipedia, the components of rap include “content”, “flow” and “delivery”, which are vaguely reminiscent of the visual art terms “concept,” “sequence” and “presentation.” Growing up, music provided a forum to explore and analyze, as award-winning journalist Ta-Nehisi Coates might put it, the necessities for surviving problems of everyday life within and outside the Black American experience. Today, my interest lies in the formality of these art forms and how best to translate them visually. An aesthetic, being ostensibly subjective, offers sight as a material to be used as one uses color, texture or form. As sight is to the visual arts, sound is to music – materials to manipulate and respond to. Furthermore, I am intrigued by the practical similarities of both music and visual art, in their ability to speak to and for their audiences. Sounds formulated into songs often become portals into yesteryear or soundscapes for an extensive but evanescent summer. What can sight formulate into? How can sight be used as a medium to spark thoughtful conversation? Can Picasso's Guernica be repeated at will, or must the visual artist wait for social uproar to amass a lasting impact? Deeply rooted in creative expression, poetry is a means to get beyond conventional reasoning just as concept provides the sublimity necessary to suspend belief. Visual artists have been doing this for years: Marcel Duchamp's urinal or Vik Muniz's depiction of (waste worker) Jardim Gramacho as radical journalist Jean-Paul Marat in Jasques-Louis David's The Death of Marat. As with David Hammons' Higher Goals my approach to object making is comparable to that of a digital recording device, perceptibly replaying discourses between Black America and its audience. Visually weaving the aura of an object with its basic function is synonymous to lyrical play and, too, possesses similar impact. Conceptual and poetic play of the two genres offers the work of the artist to transcend beyond object or record. Therefore, my efforts at object making are to reveal and discover various testimonies within and surrounding Black America.

The effect of extra feed supply on stereotypic behaviour in Asian elephants (Elphas maximus)

Björk, Kim January 2011 (has links)
Stereotypes in captive elephants is a widespread issue. Ways to tackle this is with social and feedenrichment among others. The aim of this study was to investigate if extra feed supply wouldaffect stereotypic behaviour in Asian elephants held in captivity. Three elephant cows wereprovided with extra feed and recorded during the night and morning. The results showed asignificant decrease in stereotypic behavior for one of the elephants, from 31% to 9,5% (P =0,003). While the second elephant did not engage in stereotypic behaviour, the third elephantshowed the same frequency of stereotypic behavior, 9%, during both baseline and treatment. Thethird elephant did increase her foraging significantly, from 31% to 54% (P = 0,02). Waken timespent foraging increased for all three elephants to 64-80% which is in the same range as in wildAsian elephants. Additional enrichment in the form of extra feed supply can be used both todecrease stereotypic behaviours and to increase foraging.

Synen på den avvikande individen i film : En analys av The Elephant man och Kaspar Hauser

Felczak, Isabelle January 2012 (has links)
Ämnet som jag har undersökt är synen på den avvikande individen i film. I min analys har jag använt mig av David Lynchs The Elephant man (1980) samt Werner Herzogs Kaspar Hauser (1974). Min analys är gjord utefter den hermeneutiska metoden och är således utarbetad efter mina egna tolkningar och reflektioner kring filmerna. Teorierna jag har använt mig av är postkolonialism och makt. I min slutsats har det framgått att det kan vara en mångfald anledningar till hur och varför människor väljer att behandla de avvikande individerna på sättet de gör. Dock så framgår det att de som behandlar de avvikande väl oftast motiverar sina handlingar genom att de finner sympatier för de utsatta. När det gäller de människor som ger en sämre behandling av de avvikande kan detta ofta motiveras på flera sätt. Dels så kan dessa människor ha en tro om att de gör de utsatta en ”tjänst” när de försäker omforma dem. Då man inte lyckas med omformningen legitimerar man istället att exkludera dem. Andra kan utsätta de avvikande för onda och giriga handlingar och motivera det som om de inte ser att det är människor med ett likvärdigt människovärde som de själva.

Olfactory discrimination performance and longterm odor memory in Asian elephants (Elephas maximus)

Rizvanovic, Alisa January 2012 (has links)
Behavioral evidence suggests that Asian elephants strongly rely on their sense of smell in a variety of contexts including foraging and social communication. Using a food-rewarded two-alternative operant conditioning procedure, three female Asian elephants were tested on their olfactory discrimination ability with 1-aliphatic alcohols, n-aldehydes, 2-ketones, n-carboxylic acids and with a set of twelve enantiomeric odor pairs. When presented with pairs of structurally related aliphatic odorants, the discrimination performance of the elephants increased with decreasing structural similarity of the odorants. Nevertheless, the animals successfully discriminated between all aliphatic odorants even when these only differed by one carbon atom. The elephants were also able to discriminate between all twelve enantiomeric odor pairs tested. Additionally, the elephants showed an excellent long-term odor memory and remembered the reward value of previously learned odor pairs after three weeks and one year of recess. Compared to other species tested previously on the same sets of odorants, the Asian elephants performed at least as good as mice and clearly better than human subjects, South African fur seals, squirrel monkeys, pigtail macaques, and honeybees. Taken together, these results support the notion that the sense of smell may play an important role in regulating the behavior of Asian elephants.

Investigating the effect of monetary compensation on Human-Elephant Conflict : A qualitative study in Idodi and Pawaga Divisions, Tanzania

Bergman Trygg, Elias January 2015 (has links)
ABSTRACT Bergman Trygg, E. 2014. Investigating the effect of monetary compensation on Human-Elephant Conflict, A qualitative study in Idodi and Pawaga Divisions, Tanzania. Department of Social and Economic Geography, Uppsatser: Kulturgeografiska institutionen, Uppsala University. The purpose of this study is to investigate how a compensation scheme affects farmers’ attitudes toward elephants, the Tanzanian government and the concept of conservation. Another purpose is to see what respondents know about the scheme in relation to what is written in the scheme documents. This was done by conducting 20 qualitative interviews with farmers in five different villages in Idodi and Pawaga Divisions, Tanzania. Respondents were divided into two groups: One who had received compensation and one who had not. This aimed to distinguish differences between respondent groups, hence evaluating the efficacy of the compensation scheme and how it affects their attitudes. More interviews were conducted with victims or their relatives who had been attacked by wild animals in order to see what these victims knew of the scheme and how authorities handled attacks.      Results showed small differences between the groups. Both had positive attitudes toward elephants and conservation, contradicting to what is presented in earlier studies. Attitudes toward the government were mainly negative due to suspicions of corruption. There were more positive attitudes toward the government among respondents who had received compensation. Knowledge of the scheme was low compared to what is written in the scheme documents.   Keywords: Human-elephant conflict, compensation scheme, attitudes, farmers, Tanzania   Supervisor: Bert Eriksson.
