Title

Interactions between Neighbouring Communities and Management of Okomu National Park in Wildlife Conservation

Abstract

Involvement of neighboring communities of protected areas is essential for effective conservation of natural resources in National Parks. This study aimed at determining the interactions of neighboring communities of Okomu national park in park management and to assess their willingness to support conservation initiative. A hundred and twenty (120) questionnaires were randomly administered in twelve (12) communities around the park; 10 respondents were purposively selected in each community. Descriptive and inferential (chi-square) statistics were used for data analysis. Findings from the study revealed that community involvement in park management is high in information sharing (65%), tour guide (30.8%) and decision making (25.8%), while community involvement as informant (spy) is low (10%), there was significant association between the respondent’s sources of income and level of involvement (P<0.05). However, 85% of respondents were willing to support conservation initiative in the park. Barriers affecting community participation in park conservation include lack of framework to involve communities in park management (66.6%), lack of facilities and incentives to communities (50%)and poor sensitization and mobilization (40%). The study therefore recommends that coherent interaction of neighboring communities of Okomu National park should be the major focus of the protected area manager for effective conservation and management of wildlife resources in the park.

Title

Visitors’ satisfaction and intention to revisit Agodi Parks and Garden Ibadan, Oyo State

Abstract

Visitors’ satisfaction with a recreation center is important for management activities in retaining their visitors’ influx and increasing their economic sustainability especially if their satisfaction will lead to more revisits to the center. This study identifies the recreational facilities and activities, level of visitor’s satisfaction, as well as the factors determining visitor’s satisfaction with Agodi Parks and Gardens, Ibadan, Oyo State. The study employed, direct Understanding observation and the Survey technique using structured and self-administered questionnaire to obtain information on the major objectives of the study. A total of 120 randomly selected visitors to the site were involved in the survey. Data obtained was analyzed using descriptive and inferential statistics. The results show that majority (60%) of the respondents were males, with the highest age range between 18 and 25 years. Marital status showed that 60% were single with 81.7% being resident in Ibadan. Having fun (33.3%) and relaxation (30.8%) were the major purpose of visit to the Park. Half of the respondents (50%) were satisfied with their recreation experience with 46.7% willing to re-visit. There was no significant relationship between visitor’s satisfaction and intention to re- visit. The study identified the significance of the destination attributes such as the availability of helpful staff and presence of varieties of recreational facilities as determinants of overall satisfaction of visitors to the study area. The determinants of satisfaction identified in this study should be explored to create an environment that will encourage the visitors to revisit the park, thereby increasing its economic sustainability.

Title

Determinants of Visitors’ Choice Preference for University of Ibadan Zoological Garden and Agodi Parks and Garden.

Abstract

Factors influencingvisitors’ choice preference for University of Ibadan Zoological Garden and Agodi Parks and Garden were explored in this study. Data were obtained through the use of well-structured questionnaires administered to the visitors. A total of three hundred and eight four visitors (384) were sampled. Descriptive Statistic and T- test were used for data analysis. Results revealed that majority of the visitors were females, youth, singles and most visitors were educated. Repeat visitors were more and visitation during the festive period was highest. Learning and sightseeing had the highest weighted mean of 82.07, and hence the highest influence on visitors destination choice preference at the University of Ibadan. Tourist destination respect for the natural environment(weighted mean =31.40) and opportunity for rest and relaxation (weighted mean = 31.20)were the major motives for visiting Agodi Parks and Garden. Motivating factors that influence visitors’ destination choice preference to UI Zoo and Agodi Parks and Garden were significantly different. The empirical examination of factors influencingvisitors’ choice preference will assist tourist site manager to identify the attributes that are to be promoted so as to match tourist motivations.

Influence of Interpretative Facilities on Visitors’ Experience in the University of Ibadan Zoological Garden.

Abstract

This research assessed the influence of interpretative facilities on visitors experience in the University of Ibadan Zoological Garden. Respondents in the study were visitors to the zoo and their selection was based on their willingness to participate in the study. A total of 384 visitors were selected for questionnaire administration. Data obtained were subjected to descriptive statistics. The results indicated that Museum/Education Centre, Script (Pamphlets and Fliers.), Interpretative Trails, Information Boards, Tour Guide, and Conservation Shows (Film shows) were the interpretative facilities available in the Zoo. Most of the respondents (54.4%) were female, within the age bracket of 16 and 35 years, 81.3% were single, 57.6% attained tertiary education while higher percentage (96.6%) were Nigerian. Most of the respondents (71.4%) make use of the information signs and boards while the conservation show had the least usage (24.2%). Higher percentage(52.92%) of the respondents also used an average of 1-2minutes with the interpretative signage and 25.18% use more than five minutes while the picture on the signage attracted a lot of the visitors. Knowledge about the conservation of species, species extinction and biodiversity was heightened after their use of the interpretative facilities in UI Zoo.This has influenced the visitors to care more about the individual animals they saw (Mean = 4.18) and also care for their natural habitat (mean = 4.10).Visitors’ satisfaction with interpretative facilities in UI Zoo was very high. Management of the Zoo was implored to promptly replace faulty and faded interpretative facilities for effective enhancement of their conservation education goals

Title

Assessment of employees’ perception on ICT application and contribution to hotel management in Akure, Ondo State, Nigeria.

Abstract

Hotel’s information and communication technology (ICT) has affected society and its surroundings in many ways. Most of hotels in this world use ICT as to ease their tasks such as taking reservation, room management, telecommunication, and guest accounting Azdel Abdul Aziz et al., (2012). In Akure, hotels have started to use ICT application as an important strategic asset. ICT has been rapidly changed or enhanced from time to time and many hotels invest a lot of money to ensure that they have the latest technology. This study provide information on the various ICT equipment and the perception of the employees about the use of ICT , know the contributions and challenges of ICT as these will help the management to improve more on the contributions and work on the challenges to increase the efficiency of the employees and increase revenue for the hotel. The general objective of this study is to assess the employees’ perception on information communication technology application in hotel management Akure, Ondo state. Three method of data collection were used and these include; use of structured questionnaires (administration of 133 well-structured questionnaires to employees of the hotels), oral interviews and secondary data were also conducted. The data collected was analyzed using descriptive statistics (percentage and frequency tables). Employee’s acceptance of ICT was to a larger extent with 60.2% and lesser extent with 39.8%. Two factors were identified as challenges facing hotel in the use and adoption of ICT innovations, these are lack of professionals in ICT and lack of understanding of the ICT benefits. It is therefore recommended that there should be regular training of staff both new and old whenever there is installation of ICT equipment. There should be available professional on ground to help solve the problem with ICT equipment whenever it occurs.

Effects of service quality on customers’ satisfaction in two selected hotels in Akure.

Abstract

This study assessed the effects of service quality on customers’ satisfaction in two randomly selected 3-star hotels, Sunview Hotel and Royal bird Hotels and Towers in Akure, Ondo State. The objectives of the study are to, evaluate the service quality in Sunview Hotels and Royal Birds Hotels and Tower using SERVQUAL dimensions (tangibility, reliability, responsiveness, assurance and empathy), to examine customers’ perception of service in the selected hotels, to determine if customers are satisfied or not with the service at the hotel and to examine the relationship between service quality and customers’ satisfaction. Data was obtained by the administration of 150 well structured questionnaires to customers who were present in the two hotels at the time of this study. The data obtained were analysed using descriptive and inferential statistics and the results obtained presented using frequency tables and charts. Results revealed that 60.6% of the customers were male, while 36.8% were within the age range of 31-40 years. Majority, (72.5%) visited the hotel based on recommendations from friends. Assurance and Empathy which had to do with employees paying individual attention and interacting with customers had the highest score of perceived service quality, while reliability had the least score of 34.7%. Findings also showed that majority (56.3%) of the customer were highly satisfied with the services provided at the hotels while only 1.4% were not satisfied. The correlation coefficient test revealed that there is no significant relationship between customers’ satisfaction and empathy. It is recommended that the factors which positively affect customers’ satisfaction in the hotels should be maintained and also improved upon.

Detecting the land use/land cover dynamics around ecotourism attractions and support facilities in Ikogosi Warm Spring Resorts, Nigeria

Abstract

This study focused on creating aspatial and spatial attributes of the ecotourism attractions and support facilities, as well as detecting the land use/land cover change around each ecotourism attractions and support facilities of Ikogosi Warm Spring Resorts, Nigeria. Secondary data collection method, remote sensing and geographic information technology were employed. LANDSAT imageries of two-time series (2002 and 2017) were acquired and subjected to supervised image classification in ArcGIS 10.4 software environment. A total of twenty-two ecotourism attractions/support facilities and four categories of land cover/land use were identified. Closed secondary/riparian forest covered the highest land mass of 28.11 hectares (46.84%) around the ecotourism attractions and support facilities in 2002, while the open secondary forest covered the least land mass of 0.34 hectares (0.57%). Muchmore, closed secondary/riparian forest covered the highest land mass of 24.37 hectares (40.62%) in 2017, while the open secondary forest covered the least land mass of 7.92 hectares (13.20%). Thus, degraded vegetation/farmland/lawn was the only land cover/land use classes that experienced negative absolute change (-151,009.55 hectares), percentage change (-4.69%), the rate of change (8.76%) and annual degradation change (-0.081). The study concluded that there was a slight increment in the indicator of ecotourism’s ecological impact (built-up areas/bare ground) within the time span of fifteen years most especially around some chalets and lodges. However, caution should be taken by the resort’s authority to curb the increment in this indicator through the adoption of sustainable approaches in the design and development of ecotourism attractions and support facilities.

Tourist trip profiling and determinants of their movement patterns in Ikogosi Warm Spring Resort, Nigeria

Abstract

The research studied the tourist trip profile, the factors influencing the tourists’ movement patterns and the socio-economic determinants of tourists’ preference to the Ikogosi Warm Spring Resort, Nigeria. A multistage sampling technique was used to purposively identify the tourists and to randomly select one hundred and forty six respondents. The study revealed that the majority of the tourists into the Ikogosi Warm Spring Resort were females, not married, aged 20 – 39 years, educated and earned between N12, 200 and N49, 000 monthly. The key factors that significantly influenced the movement pattern of tourists in Ikogosi Warm Spring Resort based on tourist characteristics included the trip length and/or length of stay of the respondents, profile, personal motivation for the trip, as well as security perception about the study area, while those that significantly influenced the movement pattern of tourists in Ikogosi Warm Spring Resort based on destination characteristics included the type of accommodation, number, diversity/types and hierarchy, transport network characteristics and quality, congestion, cost and affordability information. Also, marital status and occupation of the tourists significantly affected their preference for Ikogosi Warm Spring Resort, Nigeria. Hence, cordial relationship should be initiated and developed among the accommodation providers, tour operators, motor parks authorities and officials of the resort site in order improve tourist’s influx. Also, high intrinsic facilities should be installed and unevenly distributed to the more degraded environment so as to encourage more diversified tourists’ movement pattern with less environmental impact.

Publicity Challenges of Ecotourism at Ado Awaye Suspended Lake Tourist Centre, Iseyin, Oyo State, Nigeria

Abstract

Packaging and showcasing of Nigeria tourism product is at its lowest and this lack of adequate information is a minus on tourism industry performance in the country and Ado Awaye Suspended Lake especially. Some people tend to go far away from their neighbourhood not knowing that there are actually some very nice tourist attractions to hang out in their vicinity. Ado Awaye Suspended Lake is one of the only two Suspended Lakes in the whole world and the other is Hanging Lake, Colorado in USA which has been greatly utilized to the extent that the management of the site put a limit to the number of tourist that could visit the site per day.This research looked basically at the publicity challenges of Ado Awaye Suspended Lake, Nigeria. Both primary and secondary data were collected using questionnaire, interview and administrative record of the site. Data were analyzed using descriptive (charts, tables, means) and inferential (Chi-square) statistics). Findings show that there were interesting attractions at the sites, which include the Isage Hill, Iyalake Lake and Iyalaro Lake amongst others. A total of 211 visitors patronized the suspended lake between 2015 -2018 and the highest was recorded in March, 2018. Majority of the visitors were male (69.11%), 73.36% of the visitors are within the age group of 18-30 years in which 54.4% were single and 97.6% were educated. Most of the visitors were Muslim (56.9%), 43.1% were self-employed with 40.7% earning below N20, 000. They visited the suspended Lake for relaxation purpose and were motivated to visit the site based on the historical background and features of the suspended Lake.The Oba and his council of chiefs were in charge of managing the site with a total of 14 staff. Word of mouth was the leading and most effective promotional strategies as opined by the visitors, tour operators and management (mean=3.80±1.11), (mean=4.00±0.00) and (mean=4.71±0.47) respectively. Major publicity hindrances of the site include inadequate fund for advertisement, inadequate online promotion, government neglect of the site and unavailability of private investor at the site. Furthermore, visitors motivation were significantly influenced by their socio demographic characteristics such as religion and income (p<0.05) while education and age have significant relationship with their perception on the promotional strategies in use. With the intervention of the government, provision of amenities and effective promotional strategies, the destination could become a world class destination centre with greater influx of visitors which will in turn improve the standard of living of the host communities and increase the GDP of the country in the long run.

Evaluation of Conservation Education Programs in the adjoining Communities of Old Oyo National Park

Abstract

This study was conducted to evaluate the conservation education programs in the adjoining communities of Marguba, Tede, Sepeteri, Oyo-ile, and Yemoso range in Old Oyo National Park. Questionnaires, oral interview and focus group discussion were employed to collect the primary data. Forty-six communities were sampled using two hundred and seventy five questionnaires to obtain information while fifty questionnaires were administered to park staff. Data were analyzed by descriptive and inferential statistics using SPSS version 22 software. The result shows that majority of adjoining community respondents were male 72% while 28% were female. In terms of occupation, majority were farmers 87.3%. Highest percentage (71.6%) of the respondents was somewhat aware of conservation education program in the park and 40.4% occasionally participate in community meeting with park management. Majority (98%) of Old Oyo National Park staff emphasized that the park have active conservation education program. One on one mode of communication was the most effective education program in the park adjoining communities as opined by the park staff. Conservation education program has been able to encourage community members to enlighten other people on conservation issues (mean =4.96 ±0.67) and also understood that poaching activities are prohibited in the park (mean = 4.52±0.67). Management constraints identified as the threat to the effective conservation education programs by park officials and adjoining communities were inadequate funding and logistics, inconsistency in the conservation education programs, farming season, non-provision of alternative livelihood to communities among others.

Evaluating the Effectiveness of Education Programs in Environmentally Responsible Behaviour amongst Visitors in the University of Ibadan Zoo

Abstract

Zoos are invested in conservation and education and they play an important role in species preservation and in increasing their visitor level of awareness of conservation issues. The study aimed at evaluating the effectiveness of Education Programs in zoos as they enhance environmentally responsible behaviour amongst visitors to the University of Ibadan Zoological Gardens Three hundred visitors were randomly sampled with the use of structured questionnaires. Data was analysed using descriptive and inferential statistics on SPSS and Excel spreadsheet. Findings showed that 51% were male, and 36.3% were between the age range of 20-29 years, 51.3% were single, 76% has attained tertiary education, 35.3% were students. 31% of the respondents are somewhat aware of environmental conservation education. A large percentage (69%) of the respondents are aware of environmental conservation. Self-guided tour has the highest (90.7%) usage level amongst all available education programs followed by guided tour (33.3%) and interpretative signage (12.7%). The overall opinion of the respondents’ satisfaction on the education programs they have used was effective. However, the effectiveness of the education program in influencing their Environmentally Responsible Behaviour was rated generally on the minimum level with a mean of 3.84. Most of the respondents indicated a greater preference for environmental conservation television programs and shows. This study therefore recommends that there should be more input into the education program that will greatly enhance visitors environmentally responsible behaviour, through this, the zoo fulfills its major objective of providing environmental education for the visitor’s while also fulfilling their satisfaction and pleasure.

Factors affecting the participation of youth in tourism activities in Idanre Hills

Abstract

Tourism activities are as old as human race. It evolved from experience reserved for very few people to what is being enjoyed by many today. In spite of the abundance of natural and cultural tourism endowments Nigeria enjoy, the acceptance and participation of the youth in the tourism industry is still at infancy. This research is concerned about the factors influencing the participation of youth in tourism activities at Idanre Ondo State Nigeria. The research objective of this research is to determine the factors influencing youth participation in tourism activities at Idanre. A total of one hundred and fifty (150) well-structured questionnaires were administered at the three villages. Atosin, Alade and Odode (Ode- Idanre), fifty for each village. Findings from the study reveals that there were more males (55.3%) than females (43.3%) that participate in tourism activities. Also, it was observed that single youths participate actively in tourism activities than married youth. Findings also revealed that finance (42.0%)is the greatest constrain faced by higher percentages of the youths. The research recommends that the government should encourage training programs for youth who are not employed such as entrepreneurial workshops that will assist the youth to be innovative towards engaging in tourism activitiesSupport for the creation of enterprises for tourism will assist in job creation and can be used as a tool to alleviate poverty.

Comparative analysis of Landsat 8 and Sentinel 2A data on the vegetative indices of Ise Forest Reserve, Ekiti State, Nigeria

Abstract

The study determined the appropriate vegetation indices from Landsat 8 and Sentinel 2A of degraded tropical forest in Ise Forest Reserve, southwestern Nigeria. Recent Landsat 8 and Sentinel 2A satellite imageries were acquired and pre-processed. The earlier was pan-sharpened and downscaled to ensure uniformity in spatial resolution with Sentinel 2A. Seven vegetation indices [Normalized Difference Vegetation Index (NDVI), Enhanced Vegetative Index (EVI), Green Normalized Difference Vegetation Index (GNDVI), Pigment Specific Simple Ratio, Soil Adjusted Vegetative Index (SAVI), Modified Soil Adjusted Vegetative Index and Transformed Soil Adjusted Vegetative Index] were extracted from the datasets. Both Landsat 8 and Sentinel 2A have the same overall accuracy (98.00%) and kappa coefficients (0.96) in NDVI, SAVI and transformed SAVI. However, EVI, followed by GNDVI extracted from Sentinel 2A outperformed NDVI (a common and widely used vegetation index) based on their overall accuracy and kappa coefficients. The high performance of EVI (0.06 – 0.32) derived from Sentinel 2A despite the downscaling of Landsat 8 makes the consideration of spectral surface reflectance consequential. The enhanced capability and performance of Sentinel 2 in vegetation cover mapping should be more explored in developing economies with low affordability of commercial geospatial data.

Comparative analysis of two medium resolution satellite imagery on water indices of Ise Forest Reserve, Ekiti State, Nigeria

Abstract

This study aimed at evaluating the performance of Landsat 8 and Sentinel 2A in extracting the appropriate water indices for surface water area mapping of Ise Forest Reserve, southwest Nigeria. Eight index-based algorithms were employed to test the performance of satellite datasets. Landsat 8 data was subjected to pan-sharpening and re-sampling operations to ensure uniformity in spatial resolution with Sentinel 2A. The results revealed that MNDWI and AWEI_nsh extracted from pan-sharpened/re-sampled Landsat 8 and Sentinel 2A respectively performed better in the surface water area mapping. The area under water body ranges between 0 to 2.15% for all the algorithms from of Landsat 8 and Sentinel 2A. The algorithms had realistic and non-significantly different overall accuracies and Kappa coefficient ranging from 85.56% – 100.00% and 0.71 – 1.00 for Landsat 8 and 97.22% – 100.00% and 0.94 – 1.00 for Sentinel 2A respectively. Despite the good performance of Sentinel 2A with better spatial resolution, pan-sharpening and re-sampling fusion with spectral information of Landsat 8 is capable to detect and separate surface water areas from the other land cover types, especially water body mostly covered by riparian forest.

Comparison of SRTM DEM, ASTER DEM and ALOS World DSM over Cave of Ashes and Oke - Maria, Nigeria: Implications for digital terrain analysis

Abstract

A proper understanding of terrain characteristics and appropriate elevation data required for terrain mapping are important in the appreciation of aesthetic values, destination management and sustainable development of mountainous tourist sites. This study determined the topographical characteristics and the best DEM (SRTM, ASTER and ALOS World 3D) to extract accurate absolute terrain attributes of the tourism attractions/support facilities in Cave of Ashes (CoA) and Oke-Maria (OM), Ondo State, Nigeria. Field survey and geospatial technology methods using the extraction, correlation scatter plotting, DEM profiling and differencing tools were employed. A total number of 1 and 21 tourism attractions/support facilities were observed in CoA and OM respectively. ALOS W3DDSM (360.00 ± 7.37m) and SRTM DEM (496.61 ± 23.51m) had the highest mean elevations at the CoA and OM respectively, while ASTER GDEM recorded the least mean elevations at both sites as also depicted by the topographic profile line graphs.Correlation scatter plots revealed that the SRTM DEM versus ALOS W3DDSM and SRTM DEM versus ASTER GDEM had the higher and lower coefficients of determination in the CoA and OM respectively. The study revealed the sites’ potentials to high altitude associated recreation activitiesand efficiency of ALOS W3DDSM for terrain characterization. Concerted efforts should be made by major stakeholders in the destination management, infrastructure development and marketing of the two sites.

Comparison of SRTM DEM, ASTER DEM and ALOS World DSM over Idanre Hills and Oyemekun Rock, Nigeria: Implications for digital terrain analysis

Abstract

Digital Elevation Models (DEMs) have been useful for many purposes, and are an important precondition for many applications, they have been employed in regions that are devoid of detailed topographic maps. Three DEMs were compared in this research, the ecotourism and supporting facilities of the study sites were identified. This research considered the comparison of ALOS World 3D DEM, ASTER GDEM against a REFERENCE (SRTM) DEM for basic digital terrain analysis in Idanre hills and Oyemekun rock, making use of DEM differencing, correlation plot, profiling, Extract and comparison of the topographical attributes of the tourism, support facilities and human-made infrastructures. From the observed result in ALOS World 3D DSM had the highest mean elevation (352.95 and 346.36m ± 3m ) while ASTER GDEM had the least mean elevation (337.08 and 328.16m ± 3m) in Idanre hills and Oyemekun Rock respectively. ALOS World 3D DSM had the highest maximum surface area of 5,762.46 and highest maximum surface ratio of 6.02574 while ASTER GDEM had the highest minimum surface area of 956.45m2 and highest minimum surface ratio of 1.00015. From the result it was concluded that ALOS World 3D has a high accuracy in surface characteristics and elevation while ASTER has high accuracy in slope attributes. The process of using all sources of information, including global position system, digital elevation model, and topographical maps to derive an understanding of the attributes, elevation and slope characteristics of an ecotourism site terrain analysis is crucial in natural areas.

Comparison of ASTER DEM and ALOS World 3D over Ebomi Lake, Nigeria: Implication for hydrological modeling

Abstract

Morphometric analysis is a quantitative description and analysis of landforms that are applied to a particular landform or drainage basins and large regions generally to describe certain shapes of channel slopes, reliefs, area, and drainage network types. This study highlights the best Digital Elevation Model (DEM) data employed in the hydrological modeling of Ebomi Lake in Ondo State, Nigeria. Three DEM data types were employed for this study; Shuttle Radar Topography Mission (SRTM), Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) and the Advanced Land Observing Satellite (ALOS).The DEM data from the three sources were used to delineate the drainage network in Ebomi Lake basin. The delineated drainage network was then used to model the morphometric properties of Ebomi Lake Basin. SRTM was set as a standard for comparison with the other two DEMs. The correlation between SRTM DEM with ASTER DEM and ALOS DEM is very high. The correlation was observed to be almost perfect. The standard deviation indicates that ASTER DEM deviated from the mean more than that of ALOS DEM. The Root Mean Square Error (RMSE) also showed that the error in ASTER DEM was higher than that of ALOS DEM. Therefore, for morphometric characteristics analysis in Ebomi Lake, it is recommended to use the ALOS DEM because it has higher accuracy than the ASTER DEM as observed in this study.
