The effect of some latex yield stimulants on flow rate in Hevea trees was investigated using NIG 805 clone as the test clone in the clonal garden of the Rubber Research Institute of Nigeria, Iyanomo, Benin City. The Hevea trees used for the investigation were treated with four different stimulants and control, in three replicates. Each treatment, inclusive of the control, comprised of 3 trees, making a total of forty-five (45) trees. The stimulants used include; Mortex 50, Mortex 25, Vitex and Ethephon. The experiment was laid out in a complete randomised block design. Stimulation was done once in thirty (30) days and tapping done using the ½S, d/3 tapping method for a period of ninety (90) days. Data collected include girth of the trees, length of tapping cut, initial volume (volume of latex flow within the first five minutes after tapping), final volume (volume of latex flow two hours after tapping) and dry rubber content (DRC). Latex flow time for each tree was two hours. Thereafter, the flow rate was calculated and the data transformed. The results were analysed using ANOVA. There was a significant difference in the mean latex flow rate of the trees treated with Mortex 50. Similar results were obtained when the experiment was repeated the following year.
The logging of P. erinaceus popularly known as the African rosewood has increased at an unprecedented rate in recent times in Taraba State. This is in spite of the fact that the tree is a protected species, a status which made felling/local consumption and export of the species strictly prohibited. Despite the unprecedented exploitation of the tree, no research has been done in the state to understand and document the dynamics of rosewood exploitation in terms of the harvest, trade, revenue and benefit sharing as well as the socioeconomic impacts in the State. This study has examined the dynamics of rosewood production and trade in Taraba state. Data for the study were generated through the use of interview schedule and discussion with forestry officials, local community members and key informants in the study area. The findings of the study shows that this high exploitation of P. erinaceus is like a ‘rush for gold’ in which the activity is highly organized in a coordinated network that have defied all existing forestry regulations in the State. The exploitation of the log wood provided employment opportunity to many young unemployed youths in the area, thereby alleviating poverty of the rural communities grappling with endemic poverty. Almost every member of the communities involved benefitted directly or indirectly from the rosewood exploitation activities. The high revenue generated by the government, forestry officials and traditional rulers gave legitimacy to the logging activities and explains why the activity persisted despite the existing forest regulations. The activities have resulted in the depletion of the rosewood species in the early sites and a shift to other parts of the State. This has resulted in loss of biodiversity, animal fodder and important timber resources in the State. The study recommends enforcement of forestry legislation and banning of rosewood export in all forms.
Climate change has been fingered as the main factor responsible for the continuous decline in sustainable agricultural production and environmental degradation particularly in the developing countries. Against this background, a study was conducted in Uyo Agricultural Zone of Akwa Ibom State, Nigeria in 2014 from where crop farmers participating in Akwa Ibom State Agricultural Development Programme (AKADEP) activities were selected. A two-staged sampling technique was used to select one hundred and fifty (150) farmers participating in the Agricultural Development Programme (ADP) in Uyo for the study. Data were collected from primary sources using structured questionnaire and Focus Group Discussions with the farmers (respondents) in the agricultural extension block selected. Oral interview involving face to face questioning of the respondents in order to further extract more information was used to affirm opinion where need arose. Few observations were also made by the researcher. Descriptive statistics and Likert scale rating techniques were used to analyze the data. Findings revealed that out of the 23 climate change mitigation technologies identified, few (5) recorded very high adoption rate. Therefore, the null hypothesis (P= 0.05%) which stated that there was no significant difference between the sample and population means was accepted. The study recommends that Extension contact with farmers should be intensified. Also, general enlightenment campaigns to boost farmers’ participation in the ADP programmes should be sustained.
Aims: The study aimed at the identification of the disincentives hindering their on-farm cultivation in Ekiti State.
Place of Study: The study was carried out in Ekiti State, Nigeria.
Methods: A combination of social survey and direct field observation was used to assess the on-farm cultivation of indigenous fruit species (IFS) in Ekiti State, Nigeria.
Results: Twelve IFS were identified. Field observation revealed that despite the fact that these IFS were reservoirs of numerous returns in the study area, considerable number of factors threatens their cultivation hence present dependency is based on those growing in the wild.
Conclusions: Respondents’ indigenous knowledge on the identified species were documented and used for proposing conservation strategies that would enhance the sustainability of the IFS.
Uyo existed as a village until the concept of urbanization came with the advent of colonization to West Africa. Before the creation of Akwa Ibom State in 1987, Uyo was a Local Government Headquarters. Today, it is the capital of Akwa Ibom State, and the largest modern city/urban centre in the state. This present status of Uyo with increased infrastructural development and amenities is not without some ecological implications on the environment. This study was aimed at identifying some ecological consequences of urbanization of Uyo as a State capital. A combination of GIS, physical observation and field sampling and analyses were adopted in this study. The results show that vegetation cover and land use pattern have changed with increasing residential and built-up areas over the years. The ecological implications of this are enormous. Other consequences of urbanization of Uyo identified in this study include increased waste generation, increased flooding and erosion, air pollution and water and sediment contamination. It is recommended that Environmental Impact Assessment (EIA) tool should be adopted for urban renewal and infrastructural development projects to check its negative consequences on the environment. This study noted with sadness that EIA was not carried out prior to urbanization of Uyo and concludes that this may have been the cause of the many unmitigated and irreversible negative consequences of urbanization of Uyo identified during this study.
