Item Item Promotion of intra-African trade in timber and timber products(2009-07) Ajewole, O. I.Item Analysis of trends in forest charges and government expenditure of forestry in Africa(2002) Ajewole, O. I.Item Public willingness to commit time to urban forestry development in Lagos metropolis, Nigeria(2015) Ajewole, O. I.This study assessed willingness of Lagos metropolitans to commit time and the prospective number of hours to be committed to Urban Forestry Development (UFD) in the metropolis. Data were obtained from a questionnaire survey of 900 metropolitans living in three income profiled neighbourhoods using the payment card contingent valuation method. Data were analysed with descriptive statistics and Tobit model at p= 0.10. Results show that 48% of the respondents were willing to commit their time to UFD in the metropolis, out of which 13.9% were willing to commit a modal two hours per week (h/w) to the UFD. Moreover, 53.1%, 50.8%, 71.1%, 47.6%, 65.4% respectively of those who love to live or work in green environment, were aware of benefits of trees in urban environment They either belonged to social organizations, owned their residences, or previously participated in community projects and were willing to commit time to the UFD. Twelve of the 32 regressors (constant inclusive) had significant influence on the probability to commit time and the number of hours to commit per week to urban forestry development in Lagos metropolis. To harness the great pool of volunteers for urban forestry development in Lagos metropolis, promoters and protagonists of urban greening in the metropolis will have to put in place an appropriate formal public education programme to enlighten the metropolitans on the benefits of trees in urban environment; bring together social organizations, CBOs, NGOs etc. for the use o f educating and eliciting support of the public for UFD among others.Item Spatial price transmission and market integration of Cistanthera papaverifera (A. Chev.) in urban and rural sawn-wood markets, Delta state, Nigeria(2014) Ohwo, O. A.; Ajewole, O. I.; Popoola, L.The study examined the trend in prices of Cistanthera papaverifera species of sawn-wood in urban and rural sawn-wood markets in Delta State, Nigeria. Secondary data on dimensions {2”×2”×16 (0.013m3) 2”×3”×16 (0.019m3) and 2”×4”×16 (0.025m3)} of Cistanthera papaverifera species of sawn-wood monthly prices spanning 2004 to 2013 were sourced from sales receipt of sawn-wood sellers. The data were analyzed using Augmented Dickey Fuller (ADF) Test, Ravallion – IMC and Error Correction Mechanism test. Results revealed that price series in all the markets accepted the null hypothesis of non- stationarity at their levels at 1% and 5% significance level. The integration test revealed that the markets for all the dimensions of C. papaverifera species of sawn-wood considered were integrated in the long run. The Index of Market Concentration (IMC) indicates that the markets exhibit high short run market integration. The Error correction mechanism result indicated that the rates of price transfer were generally fast. This study concludes that sawn-wood marketing in Delta State have a high degree of market efficiency and recommends the provision of incentives to encourage tree planting as well as sustainable timber harvest and a greener environment.Item Willingness of herbal medicine practitioners and herbs vendors to contribute financially to conservation of medicinal plants in Ibadan, Nigeria(2014-12) Ajewole, O. I.; Oladele, A. T.; Ogunwale, A. RThe study evaluated the willingness of Herbal Medicine Practitioners (HMPs) and Herb Vendors (HVs) in Ibadan, Nigeria to contribute financially to medicinal plants conservation projects. Data was collected using structured questionnaires administered on 124 HMPs and 83 HVs randomly selected from fourteen herbal associations and marketers respectively. Results showed that 79.03%of all HMPs were males and 20.97% females while 83.13% of HVs were females and 16.87% males. All the HMPs and 97.59% of HVs were willing to contribute financially and provide useful information to conservation projects. Majority (54.84%) of the interviewed HMPs were willing to contribute between N500 - N1500 annually while most of the HVs (51.8%) were willing to contribute between N201 - N500 annually. Lack of financial power and land were identified as major constraints to holding private gardens. A total of 38 commonly used medicinal plant species was identified in the existing small scale private gardens of HMPs. There is need to organise the HMPs and HVs into formidable cooperative societies for easy access to fund and institute awareness campaign on the need for conservation of important local medicinal plants if the health for all dream is to be achieved.Item Diversity and roles of amenity trees at secretatriats' premises in Ibadan metropolis(2013-12) Ajewole, O. I.; Olajuyigbe, O. S.; Gbadamosi, S.This study evaluated the diversity and technical suitability of amenity planting of tree species inside the premises of the secretariats at Ibadan metropolis as well as the users’ perception of the trees. The trees in the seven secretariats in the metropolis were enumerated and identified to species level and were assessed for technical suitability for amenity use in work environment using selected attributes. Furthermore, forty questionnaires were administered to randomly selected respondents comprising staff in each secretariat. These questionnaires were used to examine the respondents’ perception on the benefits, threat and management of the amenity trees in the selected secretariats. A total of 260 questionnaires were retrieved and 20 were not returned. The data were analysed using descriptive statistics. The highest number of trees was found in the Oyo state secretariat (660 trees) while the lowest was in Ibadan South-West Local Government Secretariat (2 trees). A total of 30 tree species in 17 families were identified in all the secretariats. Tree density of less than one tree per square meter of land was observed for all the secretariats. Terminalia catappa was the predominant species found in 5 of the secretariats surveyed and Fabaceae was the most common family with 5 different species found during the study. Moreover, 30.8% identified the trio of cooling the environment, provision of shade and beautification of environment as a group of benefits derived from these trees. Furthermore, 69.6% suggested that more trees should be planted because the benefits outweighed the problems. Based on the traits of the identified trees in the secretariats’ premises, appropriate planting sites were recommended as suitable habitats for the trees. The study revealed that both the population and species diversity of trees in all the government secretariats with the exception of state secretariat were quite low. There is therefore a need to increase the population and diversity of the trees that will conform and be suitable for the built landscape of these premises.Item Market and marketing information of Bodija plank market in Ibadan metropolis, Ibadan, Oyo State, Nigeria(2013) Ajewole, O. I.; Fasoro, O.This study assessed the characteristics of the market and marketing information of Bodija Plank market, Ibadan with a view to suggest ways for the market to be more transparent and efficient. Twenty sawnwood traders were randomly selected from five of the nine plank market zones for administration of questionnaire. Thus primary data were collected from 100 randomly selected respondents. Data collected were analyzed using descriptive statistics. The Bodija plank market which covers a total land area of 0.12km2is made up of nine zones comprising 66 blocks and 1868 stalls. Most of the respondents (78.6%) were males, 71.6% were between the age of 30 and 49 years, 93.9% was married, 57.3% had secondary education while 62.3% had been involved in sawnwood trade between 10 and 29 years. The prevailing type of differentiation in the plank market is the horizontal product differentiation which is linked with strength, colour, species, size, function and method of production. Thus 26 wood species, six sizes and two production methods were identified as sources of product differentiation in the market. Therefore 74.5% and 11.2% of the respondents identified strength as well as colour and strength as the main reason why some species are in relatively high demand. The structure of the market is somewhat monopolistic competitive in nature because of the existence of the Oyo State Plank Market Association which determines who can sell sawnwood in the market as attested by 81.6% of the respondents, thereby constituting an entry barrier to the plank market. All the respondents made use of phones to collect and disseminate marketing information, 80.6% were aware of the internet, but only 7.1% made use of internet to collect and disseminate marketing information. Prices and availability of sawnwood were the essential marketing information that the sawnwood traders always look for as reported by 56.1% of the respondents while market and customers were respectively reported by 35.7% and 37.8% of the respondents as the main sources of marketing information. Furthermore, 73.5% of the respondents posited that most of the sawnwood sold in the market are from outside Oyo State. Promotion of transparent and efficient marketing of sawnwood in Bodija market will require first the production and use of wood quality manual which contains objective measurable wood quality parameters for ranking wood species in order of suitability for specific purposes and second the development by forestry related institutions a Marketing Information System (MIS) for sawnwood.Item Students' knowledge and perception of functions and management of trees in the trees in the University of Ibadan(2012-01) Ajewole, O. I.; Owoeye, F. AThis study assessed the perception and level of information about trees possessed by the students in the University of Ibadan in order for the trees’ managers to develop appropriate management strategy for sustainable production of the trees’ service functions for the optimal and continuous benefits of the students. A two-stage stratified random sampling procedure was used to administer questionnaire on 315 respondents drawn from all the halls of residence (11) and faculties (10) in University of Ibadan. Hence, 165 respondents were randomly selected from the 11 halls of residence, while 150 respondents were randomly selected from the 10 faculties, making a total of 315 respondents.The data collected were analysed with descriptive statistics and Chi-square (χ2) at p = 0.05. Most (90.6% and 95.2%) were aware of presence of trees around their classrooms and halls of residence respectively. Students’ awareness of presence of trees around classrooms is not dependent on the faculty of the students while awareness of presence of trees around halls of residence is dependent on the halls of residence of the students. Cooling the environment ranked highest (31.3%) among the identified functions, while provision of shade ranked highest (30.1%) among the benefits derived from the campus trees. Although 68.2% iterated that trees do not pose danger on the campus, 82.8% identified falling down of trees during windstorm and falling of old weak trees as major threatsby trees, while 56.7% identified old age of trees as a major reason for tree hazards. Furthermore, 72.9% was of the opinion that the trees on the campus should not be removed, 95.4% was of the view that trees are necessary within the premises of the campus; 90.9% opined that more trees should be planted in the university; 94.2% agreed that trees beautify and make the environment attractive; 90.9% indicated that trees purify the air we breathe; 89.0% was of the opinion that trees in the University premises make the environment to be serene while 74.1% consented that presence of trees marks the university premises out from the surrounding environment. Moreover, 92.6% believed that proper management of trees in the University can reduce hazards associated with the trees, 74.7% was at variance with the statement that trees in the University campus are too many and should be reduced, 80.7% concurred with the statement that old trees within the premises should be replaced by newly planted ones, 77.5% acceded that asides replacing old ones, more trees should also be planted on the University campus. Moreover, 75.5% subscribed to forestry education not being limited to the Department of Forest Resources Management while 77.5% saw the need for awareness campaign for planting of trees on the campus. The Campus Tree Management Committee will have to expedite actions towards mitigation of tree hazards and have to be more feasible, proactive and creative in developing sustainable greenery for the University environment. Also the Department of Forest Resources Management course on Introduction to Forestry (FRM 210) and that of the Faculty of Agriculture and Forestry General Study course (GES 105) will have to be reviewed to incorporate a chapter each on the fundamentals of Arboriculture.Item Evaluation and users' view of amenity trees in the premises of selected public hospitals in Ibadan metropolis(2012-01) Ajewole, O. I.; Oladipupo, AThe study enumerated and assessed tree species found in selected hospitals’ premises in Ibadan for amenity planting. The study also examined the premises users’ awareness of the benefits and probable threats posed by the trees as well as the premises users’ willingness to support conservation of trees in the hospital premises. Five public hospitals were purposively selected for the study. Trees in the selected premises were enumerated and their suitability as amenity trees was evaluated by identifying the desirable and undesirable attributes of the species. Data on availability of requisite institutional structures for sustainable management of the amenity trees were collected by administration of questionnaire on the officials of the units/ departments (works or maintenance) in the hospitals that are responsible for the management of the physical environment of the hospitals. Information on users’ views of the trees was collected through administration of questionnaire on 40 randomly selected staff members in each of the selected hospitals. Thus a total of 200 questionnaires were administered in the five hospitals. Data collected were analyzed with descriptive statistics. A total of 354 trees comprising 12 species were enumerated in the hospitals’ premises. The identified species are Delonix regia, Mangifera indica, Plumeria rubra, Polyalthia longifolia, Roystonea regia, Terminalia catappa, Pinus caribea, Elaeis guineensis, Tectona grandis, Dacryodes edulis, Gliricidia sepium, and Samanea saman. Most of the identified species have more desirable traits for amenity planting than undesirable traits. Cooling the environment (25.67%), provision of shade (25.67%) and beautification (24.78%) of environment top the list of services derivable from the trees in the hospitals’ premises. Furthermore, 76% of the respondents opined that trees do not constitute hazards, 58.5% observed that leaves and fruits of trees litter the premises regularly, 66.7% claimed that trees occasionally fall on the roads as a result of windstorms while 58% was willing to support planting and management of the trees in the hospital premises. Since trees provide salient benefits to the users of hospital premises, hospital management should consider treescape as a basic and important infrastructure that should be incorporated into the physical planning of the hospitals. Forestry professionals however have to help hospitals’ management boards to create a functional and conducive treescape necessary for the uplift of wellbeing of hospital premises users.
