Consumptive wildlife utilization as a land-use form in Namibia

Erb, Karl Peter 03 1900 (has links)
Thesis (MBA)--Stellenbosch University, 2004. / ENGLISH ABSTRACT: This study summarizes data for the consumptive wildlife industry in Namibia, both in terms of resource availability and current utilization and monetary value. Based on these data a spreadsheet-based cash-flow model is developed to simulate scenarios and to explore what constitutes the critical parameter. Based on this data synthesis and modelling, recommendations are made and conclusions drawn. Chapter one gives an overview of Namibia's economy, with special reference to the livestock and wildlife industry. The fact that the commercial livestock herd has been shrinking over the years is pointed out, as well as the stable output achieved through better management practices. The literature research has shown that wildlife ranching could be a viable alternative to livestock farming as practised in southern Africa, especially in the more arid areas with higher rainfall variability. Chapter two outlines the resource availability, based on the distribution and densities of the more common species. The occurrence of the rarer species is touched on. The point is made that it is very difficult to accurately count wildlife over large areas and that, as elsewhere, Namibia's wildlife at a regional scale is underestimated. Chapter three documents the consumptive use of wildlife. Trophy hunting, the most important segment in terms of national income, is discussed together with the live sale of game, live export of game, venison production and night culling. A comparison is made between the economic outputs of the wildlife industry versus that of the commercial cattle industry. Chapter four covers financial modelling and the economics of the wildlife industry in Namibia. A spread-sheet based deterministic model is developed to explore the cash-flow implications of various game ranching options, such as using different species mixes, owning land of different carrying capacities and offering different services. Chapter five addresses policy and legislative issues in relation to the wildlife industry. Topics such as property rights and exclusive utilization rights, industry representation and the forming of smart partnerships with primary resource users are covered. Broad recommendations are made to the Ministry of Environment and Tourism. Chapter six is used for a concluding synthesis of the previous four chapters. / AFRIKAANSE OPSOMMING: Hierdie studie som die konsumptiewe wildlewe industrie in Namibie op in terme van van beide beskikbaarheid, huidige verbruik en monetere waarde van hierdie hulpbron. Gebaseer op hierdie data is 'n kontantvloei model opgestel om vooruitskouings te simuleer, met betrekking op aanbevelings en gevolgtrekkings. Hoofstuk een gee 'n oorsig van die Namibiese ekonomie met spesiale verwysing na die vee- en wildboerdery. Daar word uitgewys dat die gesamentlike kommersiele veekudde oor die afgelope aantal jare kleiner geword het, terwyl die opbrengs stabiel gebly het deurdat better bestuurspraktyke toegepas is. Die literatuurstudie het gewys dat in suider-Afrika, wildlewe-boerdery 'n lewensvatbare alternatief kan wees vir veeboerdery, veral in die droër streke wat 'n hoër reenval speling toon. Gebaseer op die verspreiding en digtheid van die meer algemene wild, gee hoofstuk drie 'n oorsig van die beskikbaarheid van hierdie hulpbronne. Trofeejag, wat die belangrikste inkomstesektor is, word bespreek, sowel as die lewende verkoop, uitvoer en nagoes (skiet van diere gedurende die nag vir vleisproduksie) van wild, asook die wildvleis produksie. Met betrekking tot die ekonomiese uitsette, word 'n vergelyking gemaak tussen die wildlewe en kommersiele veeboerdery industrie. Hoofstuk vier dek die finansiele modelering en ekonomiese aspekte van die wildlewe industrie in Namibie. 'n Rekenaar "spreadsheet" -gebaseerde, deterministiese model is ontwikkel om die kontantvloei van verskeie opsies van wildlewe boerdery te verken. Voorbeelde sluit in die gebruik van verskillende spesie samestellings, die besit van grond met verskillende drakrag vermoëns, asook die aanbiedinge van verskeie dienste. Hoofstuk vyf bespreek die beleid en wetgewing met betrekking tot die wildlewe industrie. Onderwerpe soos eiendomsreg en eksklusiewe benuttingsregte, industrie verteenwoordiging en die stigting van "smart" vennootskappe met primere hulpbron verbruikers, word aangespreek. Aanbevelings word aan die Ministerie van Omgewing en Toerisme gemaak. Hoofstuk ses behels 'n sintese van die voorafgaande vier hoofstukke.

Evaluation of spoor tracking to monitor cheetah abundance in central northern Namibia.

January 2007 (has links)
The design, implementation, management and the evaluation of sound conservation practices, is often dependent on the availability of reliable estimates of animal abundance. Large carnivores often pose particular problems in this regard, due to their low densities and wide-ranging behaviour, so the true abundance of such species are seldom able to be reported in literature . As a result, the use of indices of abundance, mostly for relative abundance, has been investigated. However, before these indices can be reliably utilized for conservation purposes , there is a pressing need to calibrate them. As of yet, calibration studies have primarily been performed on demarcated conservation areas, where individuals could be individually identified. Not all these calibrations studies reported indices to be a function of true density. Nevertheless , spoor frequency has been reported to be a function of true density for carnivores in certain Parks in Namibia . Precisely , cheetah spoor density was reported to correlate with visuals in the Kgalagadi Transfrontier Park. The majority of these studies elucidate a species spatial organization, animal behaviour, as the paramount factor determining the relationship between densities estimated via different censusing methods. Thus, the efficiency of spoor frequency to estimate and monitor relative abundance for wild cheetahs is yet to be empirically tested . Despite the lack of a true density estimate for the free-ranging cheetahs in the study area, evaluated spoor tracking as a possible index to monitor relative cheetah abundance using radiotelemetry densities estimates as representative of true abundance for the area, for the 1995 to 2000 period. The study is considered to be opportunistic , and a pillar for future research, as transects where spoor tracking was conducted were layout primarily for ungulates strip counts. Least-linear regression and Spearman's correlation were used to evaluate the relationship between density estimates derived by the two methods. Percentages of change on annual densities were also regressed as a mean to test spoor frequency sensitivity to density changes. The calibration of spoor frequency with estimates of density produced using radio-telemetry, without the ascription of imprints to individual animals, was poor (rs=17.4, y=0.36+0.20). The sensitivity analysis also showed spoor tracking poor reliability to monitor cheetah population. This can be attributed, in order of importance, to the discrepancies on the spatial extent sampled by the two methods, the species large home ranges, substrate quality , habitat preferences, the availability of farm road networks and the transect design, i.e., cyclic. However, the paramount factor limiting the study conclusions was the lack of a more local density estimate at a farm level. Therefore, the use of spoor frequency to estimate wild cheetah relative abundance requires further research, particularly using a different sampling design, longer straight transects and the acquisition of local densities estimates. / Thesis (M.Sc.)-University of KwaZulu-Natal, Pietermaritzburg, 2007.

Farmer-related threats to cheetah (Acinonyx jubatus) survival in Namibia.

Orford, Penelope Jane. January 2002 (has links)
This mini-dissertation is a comparison, by repeat survey, of farmer-related threats to cheetah (Acinonyx jubatus) survival on specific commercial farms in central Namibia. The research was conducted, to investigate if there had been changes in these threats to cheetah survival over a ten-year period (June 1991 to October 2001). A sub-sample of 31 farmers who were originally interviewed by the Cheetah Conservation Fund in June 1991, were re-interviewed between July and October 2001. These farmers were exposed to the Cheetah Conservation Fund awareness-raising programme. The results of this survey were compared to the results of the original survey of these farmers. This study showed that changes in farmer-related threats to cheetah survival have taken place. These include changes in land use, the attitude and behaviour of farmers towards cheetah, and cattle management practices. The land use changes include an increase in game farming, as a major source of income, by 19% of the farmers, since 1991. This increase in game farming was associated with an increase in game proof fencing and the introduction of alien antelope species into game fenced areas. The attitude of farmers towards the presence of cheetah on their farms was found to have changed significantly (p = 0.024), with 13% more farmers than before 1991 favouring cheetah presence on their farms. The behaviour of farmers towards cheetah has also changed in favour of cheetah survival. During the ten-year period from 1991 to 2001, 23% of the farmers removed no cheetah, compared to 10% for the ten-year period before 1991. Thirteen percent of the farmers were found to remove cheetah by trophy hunting only, as opposed to none prior to 1991. During the ten-year period from 1991 to 2001, the number of cheetah removed by the same farmers had declined by 243 (55%) cheetah when compared to the previous ten-year period. Game farmers were found to remove on average 3.75 times more cheetah than livestock farmers. Five game farmers were responsible for removing 92 cheetah, representing 47% of the total number of cheetahs removed. The majority (88%) of cattle farmers experienced calf losses to cheetah predation. In contrast to this, only 44% of smallstock farmers experienced losses to cheetah predation. The mean loss of livestock to predation by cheetah was found to be low, less than one animal per year for both calves and smallstock. The majority (73%) of cattle farmers implement only one livestock management strategy to prevent predation on calves by cheetah. The majority (88%) of smallstock farmers implemented more than one strategy to prevent predation. Changes in management practices to protect calves from cheetah predation since 1991 included a 14% decline in farmers using a technique known as 'calving camps' and an increase of 42% in the number of farmers monitoring their cows during the calving season. In conclusion, during the ten-year period from 1991 to 2001, both positive and negative changes in farmer-related threats to cheetah survival were recorded amongst the farmers interviewed. The positive changes include changes in the attitude and behaviour of farmers in favour of cheetah survival. However, this progress was tempered by change in land use from livestock to game farming, since game farmers pose a greater threat to cheetah survival than livestock farmers. / Thesis (M.Sc.)-University of Natal, Pietermaritzburg, 2002.

Reciprocal impacts of black rhino and community-based ecotourism in North-West Namibia

Beytell, Petrus Cecil 12 1900 (has links)
Thesis (MA (Geography and Environmental Studies)--University of Stellenbosch, 2010. / ENGLISH ABSTRACT: This research focuses on the black rhinoceros and ecotourism in three conservation areas in the Kunene region of Namibia. The reciprocal impact between black rhino and community-based ecotourism is analysed. The research is located in two communal conservancies, #Khoadi-//Hôas and Torra, and in a photographic tourism concession, the Palmwag Concession Area. The research aims to explore and describe the reciprocal impact of community-based ecotourism efforts and black rhino spatial movement patterns in three conservation areas in north-west Namibia. An in-depth literature review was undertaken on the reciprocal impact between rhino-tracking tourism and conservation. A comparison was also made between the effects of human-induced disturbance on spatial movement patterns of black rhinos and the perception of tourists about tracking black rhinos. The value of black rhinos to community-based ecotourism was also determined. Quantitative research methodology was used for this study. Explorations of objectives were conducted through direct field observation with the aid of radio-telemetry tracking and aerial surveying for data gathering. The researcher employed SRT (Save the Rhino Trust) trackers in the study areas to assist with the tracking. The sample consisted of 24 transmitter-fitted black rhino in the three conservation areas. Rhino not fitted with transmitters have been included in the sample for more accurate results. Four hundred questionnaires were distributed at four tourist lodges in the study area. The hypothesis that sustainable ecotourism does not influence black rhino spatial behaviour was rejected. Rhinos in the study were easily disturbed and did not readily return to undisturbed behaviour. Their major response to disturbance was to run away. The disturbance was influenced by their initial activity when found. The highest disturbance occurred early in observations. Rhinos illustrated similar causes of disturbance throughout the study sites. The Springbok River emerged as the area with the most severe reactions to disturbance. This was supported by home range data and ecological constraints. Analysis of tourist responses regarding rhino tracking indicated a high demand for and level of satisfaction. This was the single determining factor for tourists to return to the Kunene region to do rhino tracking again. Tourists were willing to pay close to market price to track black rhino. It is recommended that tracking of black rhino should be avoided in the Springbok River and Aub/Barab areas. Tracking protocols should stipulate that tracking should only be conducted early in the morning; that rhinos may only be approached from downwind; that observation time may not exceed 15 minutes; that groups must be kept small; and that the approach distance may not be less than 100 metres. / AFRIKAANSE OPSOMMING: Die fokus van die navorsing is op swart renosters en ekotoerisme in drie bewaringsgebiede in die Kunene streek van Namibia. Die wedersydse wisselwerking tussen swart renosters en gemeenskaps-gebaseerde ekotoerisme is nagevors. Die navorsing het plaasgevind in twee kommunale bewaringsgebiede, #Khoadi-//Hôas en Torra asook ‘n konsessie vir fotografie in die Palmwag Konsessie Gebied. Die doel van die navorsing was om die wedersydse wisselwerking van gemeenskapsgebaseerde ekotoerisme en swart renosters se geografiese bewegingspatrone in drie bewaringsareas in noordwes Namibië te ondersoek en te omskryf. ‘n Deeglike literatuurstudie is gedoen ten opsigte van die wedersydse wisselwerking tussen toerisme met die doel om renosters waar te neem deur spoorsny en bewaring van die spesies. Die uitwerking van versteuring deur mense op die geografiese bewegingspatrone van swart renosters is vergelyk met die persepsie van toeriste ten opsigte van spoorsny van swart renosters. Die waarde van swart renosters ten opsigte van ekotoerisme is ook bepaal. Kwantitatiewe navorsingsmetodologie is gebruik in die studie. Die doelstelling van die navorsing is uitgevoer deur direkte veld waarnemings met behulp van radio-telemetriese opsporing en data insameling met behulp van lugsensusse. Die navorser het spoorsnyers van SRT (Save the Rhino Trust), wat in die studiegebied werk, in diens geneem om van hulp te wees met die spoorsny van renosters. Die steekproef het bestaan uit 24 swart renosters toegerus met seintoestelle in drie bewaringsgebiede. Renosters wat nie seintoestelle gehad het nie, is ook in die steekproef ingesluit ten einde beter dekking te verkry. Vierhonderd vraelyste is by vier toeristeoorde in die studiegebied versprei. Die hipotese dat volhoubare ekotoerisme nie ‘n invloed uitoefen op die geografiese gedrag van swart renosters nie, is verwerp. Renosters in die studie-gebied is maklik versteur en het nie geredelik teruggekeer tot onversteurde gedrag nie. Hulle reaksie op versteuring was gekenmerk deur weg te hardloop. Die mate van versteuring is bepaal deur die renosters se aanvanklike aktiwiteit by opsporing. Die meeste versteuring het gedurende vroeë waarneming plaasgevind. Dieselfde oorsake van versteuring is in al drie gebiede gevind. Die Springbokrivier was die gebied waar die sterkste reaksies ten opsigte van versteuring bespeur is. Dit word ondersteun deur die grootte van die loopgebiede van die renosters en ekologiese beperkings van die gebied. Data-analise van toeriste-vraelyste het aangetoon dat daar ‘n groot aanvraag en belangstelling is in die spoorsny van renosters. Die grootste bepalende faktor vir toeriste om na die Kunene streek terug te keer, is om renosters te sien deur middel van spoorsny. Toeriste is gewillig om die heersende markprys vir spoorsny van renosters te betaal. Navorsingsaanbevelings sluit in dat spoorsny van swart renosters in die Springbokrivier en Aub/Barab gebiede vermy word. Spoorsny-protokol moet stipuleer dat dit net in die vroeë oggend gedoen word, dat renosters slegs van onderkant die wind genader word, waarnemingstyd mag nie 15 minute oorskry nie, groepe moet klein wees en die afstand vanaf die diere mag nie nader as 100 meter wees nie.

An assessment of community understanding of the Human Animal Conservancy Self-Insurance Scheme and the impact of human-wildlife conflicts : a case study from the Kwandu conservancy, north-east Namibia.

Kasaona, Marthin Kaukaha. January 2006 (has links)
The research problem of this mini-dissertation involves the conflicts between human and wildlife populations and the trialing of ‘compensation’ payouts that are emerging as a critical test within the conservancy. Crop raiders such as elephants, buffaloes, hippopotamus, bush pigs and small rodents, diminish farmers’ resource bases and cash crops, while carnivores are responsible for livestock losses. The aim of the research is to assess the level of community understanding of the compensation scheme and the impact of human wildlife interaction within the conservancy. This mini-dissertation investigated the level of community understanding about the Human Animal Conservancy Self-Insurance Scheme (HACSIS), and the impact of human-wildlife conflicts within the Kwandu Conservancy. Some of the research data were obtained from the conservancy game guards’ event book system, and the actual field research data were collected from the 1st August to 20th August 2006. The researcher conducted a total of 35 interviews, whereby 32 involved face-to-face interviews with single individuals, and 3 separate focus group discussions that consisted of four, five and two conservancy members. The interviews averaged 30 minutes in length. Each interview was preceded by a careful explanation of the purposes of the work, stressing that the intent was to evaluate their understanding and perceptions on HACSIS, the impact of human-wildlife conflicts and to explore better management strategies. The researcher has taken into account that the communities might exaggerate the wildlife problem based on his previous experience with the adjacent conservancy, in the hopes of gaining more compensation – they also use the researcher as a way to vent their frustration at the problem. On the assumption that there may be an element of exaggeration verification of these was obtained from the Event Book System (a manual book used by the Community Game Guards for recording both crops and livestock incidents on daily basis). This mini-dissertation reveals that 74.3 % (n = 26) of respondents are aware of the existence of the HACSIS program and its role, while 17.1 % of respondents had no idea about the scheme’s presence and its involvement to minimize the impact felt by communities when they lose livestock to predators. The percentage of respondents who claimed that they had heard of the scheme’s existence but had no knowledge of its role was 8.6 %. In addition, most respondents (n = 15) claimed that the conservancy committee did not explain to them why their claim forms were rejected. In contrast, some respondents (n = 6) did received feedback on rejected claim forms. HACSIS was not formed to compensate livestock losses based on market value, nor was it intended as a ‘compensation’ scheme. Its aim was to test a conservancy-run process – local verification of claims and monitoring by conservancy committee and traditional authority. In addition, the authorization of payments for a type of ‘self-insurance’ is drawn from conservancy income to partially offset the losses of conservancy members versus the overall gains that wildlife brings to the conservancy (direct conservancy income and local jobs through tourism, trophy hunting, own use game harvesting). Conservancy committees and the support NGO, IRDNC, agreed on the amount to be refunded for animal losses before the scheme was started, initially using donor funding in the trial phases. The amount was deliberately kept low as it was acknowledged from the start that conservancies themselves would take over the repayments from their own income. Once the conservancy was used to its own income to finance the scheme, conservancy members could vote to increase amounts paid for predator losses. The crucial aspect, according to IRDNC, was that the process itself be tested and that the scheme be run by the conservancy, with Ministry of Environment and Tourism and IRDNC merely monitoring and providing assistance as needed. Compensation is based on this pre-determined amount that is less than the livestock value. However, the research reveals that respondents (n = 19) were dissatisfied with the amount paid (N$ 800-00 per ox killed), because they claim that the amount paid to relieve the immediate impact from wildlife is too little to sustain the affected member. In contrast, some respondents (n = 8) were satisfied with the amount paid as compensation. Despite criticisms about the amount paid for livestock losses, none of the respondents (n = 22) who were familiar with the scheme wanted it to be abolished. The respondents emphasized the need for the conservancy committee to review the amount paid as compensation, especially for cattle. They suggested an increase from the current N$ 800-00 to N$ 1000-00 per ox loss. The research reveals that community livestock management practices have not changed to deliberately benefit from the compensation. In fact community management strategies have improved because of the condition set by the review committee dealing with the compensation scheme. Wildlife incidents have increased because animals are habituated to techniques used by communities to deter them and this has contributed to high livestock incidents. For human-wildlife conflicts, the research acknowledges that the conflict exists. Between 2003-2005, the Kwandu Conservancy reported 1508 incidents of damage to crops by wildlife. Species that were responsible included elephants with 30.2 % damage, bush pigs (29.8 %), hippopotamus (12.7%), antelopes (12.7 %), porcupine (7.5 %), and baboons/monkeys (7.2 %). Most of the crops destroyed by crop raiders, as suggested by the respondents, were maize (30 %), sorghum (26 %), millet (17 %), groundnuts (14 %), pumpkins (8 %) and beans (5%). During the same period of crop losses, the conservancy reported 98 livestock incidents. Animals responsible for livestock incidents were crocodile with 32 incidents (32.7 %), then hyena (23 incidents, 23.5 %), leopard (22 incidents, 22.4 %) and lion (21 incidents, 21.4%). The role of community game guards was found to be extensive. From a total 35 responses, 74.3 % (n = 26) of members stated that community game guards effectively record incidents, chased problem-causing animals from the community crop fields by shouting or shooting in the air, and assessed or verified killed livestock for compensation purposes. In addition, community game guards conduct crop assessment for record-keeping purposes. The scheme for crop compensation is to be introduced in 2007. Currently there is no proper formula to use in assessing the value of crops and the method to use to compensate the affected members. Other methods used by communities to deter wildlife include sleeping in the field to guard crops, cracking a whip, construction of human statues, hanging tins on the fence, chilli coils, watchtowers and digging trenches. Respondents had different views on the best management practices for problem-causing animals. The response was generally based on the degree of threat that the animal posed. Most (43.8 %, n = 14) preferred the monitoring of problem-causing animals that are sighted in an area as a best practice, while 40.6 % (n = 13) of respondents preferred the animal to be captured and relocated to parks. Only 25.6 % (n = 5) of respondents preferred that the animal be destroyed. The management practices preferred by respondents when an animal kills a person are different from when an animal is simply sighted in the area. If an animal kills a person, only 12.5 % (n = 4) of respondents preferred that the animal be captured and relocated to parks, while 87.5 % (n = 28) of respondents preferred the problem-causing animal to be destroyed. None of the respondents suggested monitoring as the best management option for this degree of threat. In conclusion, the research revealed that Human Animal Conservancy Self Insurance Scheme does not treat the cause of the problem but the symptom. This approach does not decrease the level of the problem given that the cause of the problem is not addressed. Therefore, the researcher stressed the need to fully explore and implement the recent piloted lion, crocodile fencing, and elephant proof fencing and elephants chilli coil to address and reduce the problem within Kwandu Conservancy. In addition, the research revealed that the scheme has very lengthy delays before compensation is paid and the review panel does not arrange meetings on the stipulated dates. This causes a back-log in the number of claims that need to be reviewed and approved. On Human Wildlife Conflict the research findings recommend the need to strengthen and improve existing problem-causing animal management strategies that are in place. Innovative strategies include reducing the number of stray livestock at night and developing static fences. Communities should be advised, as is being done by IRDNC, to herd their livestock during the day and to build strong kraals. This is the most effective and cheapest way to prevent livestock from being taken by predators at night. Further more the research revealed that the combination and rotation of the methods yield high success rather than deploying a single method over a long period, for the prevention of crop losses methods include guarding the crop field, cracking a whip, shooting in the air, watchtowers, human statues and beating drums. / Thesis (M.Env.Dev.)-University of KwaZulu-Natal, Pietermaritzburg, 2006.
