Factors affecting adoption behaviour of Agroforestry practitioners in Atisbo local government area of Oyo state, Nigeria
(2007) Azeez, I. O.; Jimoh, S. O .; Amusa, T. O.
The importance of trees and shrubs in fallows or in food crop production systems cannot be overstressed in view of the fragile nature of the tropical environment, increase in population density, rate of forest diminution and increasing land shortage. This has given rise to the technology of Agroforestry. Evolving technology to meet any need will be incomplete without taking cognizance of the end-users no matter how perfect. This study investigates the factors affecting adoption behaviour of agroforestry practitioners in Atisbo local Government Area of Oyo state. Using a purposive simple random technique, a total of one hundred and fifty questionnaires were administered to selected agroforestry farmers in the study area based on membership of Atisbo Farmers' Association of Nigeria (AFAN). Data generated were analyzed using descriptive and inferential test statistics. Results reveal variants of agroforestry system among the respondents. These include; the tree crop system (67.3%); Mixed home gardening (22.7%); Alley cropping (7.3%); Bush fallow (2.0%); and Taungya (0.7%). Farmers income level and extension contact were two variables that significantly associate with adoption of agroforestry technology (χ2; 7.651, 47. 680; P<0.05). There is also a positive and significant correlation between adoption and scale of farming, total farm size, socio status on land and type of agroforestry system. The financial implication of practicing agroforestry system is the most important determining factor affecting adoption and application.
Population distribution and threats to sustainable management of selected non-timber forest products in tropical lowland rainforests of south western Nigeria
(Northeast Forestry University and Springer-Verlag Berlin Heidelberg, 2013) Jimoh, S. O.; Amusa, T. O.; Azeez, I. O.
Uncontrolled harvesting of non-timber forest products(NTFPs) poses a serious risk of extermination to several of these species in Nigeria. Yet, there is a paucity of information on the distribution, population status and sustainable management of NTFPs in most of the tropical lowland rainforests. We, therefore, assessed the population, distribution and threats to sustainable management of NTFPs within the tropical lowland rainforests of Omo and Shasha Forest Reserves, south western Nigeria.Data were obtained through inventory surveys on five top priority species including: bush mango (Irvingia gabonensis (Aubry- Lecomte ex O'Rorke) Baill),African walnut (Tetracarpidium conophorum (Mull.Arg.)Hutch. & Dalziel syn. Plukenetia conophora), chew-stick (Massularia acuminata(G. Don) Bullock), fever bark (Annickia chlorantha Setten&P.J.Maas syn. Enantia chloranta) and bush pepper (Piper guineense Schumach. & Thonn.).Purposive and stratified random sampling techniques were used for the inventory. Each forest reserve was stratified into three, viz: less disturbed natural forest (for areas that have been rested for at least ten years), recently disturbed natural forest (for areas that have suffered one form of human perturbation or the other in the last five years), and plantation forest (for areas carrying forest plantation). Data were collected from eighteen 10 m ×500 m belt transects located in the above strata. The species were generally fewer in both plantation and recently disturbed natural forest than the less disturbed natural forest, suggesting that forest disturbances (habitat modification) for other uses may have an effect on the occurrence and densities of the NTFPs. Exceptions to this trend were found for P. guineense and T. conophorum, which were fairly common in both planta tion and recently disturbed natural forest. Among three tree NTFP species (i.e. I. gabonensis, M. acuminata and A. chlorantha), only I. gabonensis showed a significant difference in overall DBH size classes for both reserves (t=-2.404; df =21; p=0.026).Three tree NTFP species in both reserves further showed differences from the regular patterns of distribution of trees. The fairly regular reverse J-shaped size class distribution observed for M. acuminata in the study sites, however, suggests a recuperating population. In general, destructive harvesting of species, logging operations, low population size, narrow distribution ranges and habitat degradation are the major threats to the population of NTFPs in the study area. The implications of our findings for sustainable management of NTFPs in the study area are discussed and recommendations are made for a feasible approach towards enhancing the status of the species
Prevalence, Utilization and Conservation Strategies for Non-Timber Forest Products in South western Zone of Nigeria
(Scientific & Academic Publishing, 2012) Jimoh, S. O.; Amusa, T. O.; Azeez, I. O.
The study was carried out to investigate the prevalence and utilization of non-timber forest products (NTFPs) plant species in Omo and Shasha Forest Reserves, Southwestern Nigeria. Data were obtained through the use of structured questionnaires administered to households in forest communities. To complement information from the household survey, focus group discussions (FGDs) were also carried out in each of the sampled communities. In-depth interview (IDI) of forestry staff was further used to supplement the information collected. A simple random sampling technique was employed for the study. In Omo Forest Reserve (OFR), a total of seventy five species distributed in forty three families were recorded, while fifty six species in thirty one families were documented in Shasha Forest Reserve (SFR). Local end-uses of NTFPs include food and food supplements, snacks/sweeteners, wrapping leaves, soup and spices, beverages, dental care supplies, washing tools, roofing/construction materials, medicine and traditional rites items. While access to these resources is important to guarantee the socio-economic well being of the forest dwellers and communities, their sustainable management has not been taken seriously by policy makers thereby contributing to reduction of biodiversity and gradual but irretrievable loss of indigenous knowledge on the uses of most species. To ensure the sustainable utilization of NTFPs in these and similar tropical forest environments therefore, a number of conservation approaches are proposed.
Socio-Economic Determinants of Consumer Demand for Non- Timber Forest Products in Ogun and Osun States, Southwest Nigeria
(2013) Amusa, T. O.; Jimoh, S. O.; Azeez, I. O.; Adefalu, L. L.; Oladipo, F. O.
There is a dearth of research effort on the individual and household characteristics that affect the consumption of _on-Timber Forest Products (_TFPs) in parts of Southwest _igeria. Yet, understanding the factors driving demand for _TFPs is crucial for managing supplies sustainably. Therefore, this study examined the socio-economic determinants of consumer demand for _TFPs in Ogun and Osun States, Southwest _igeria. A survey involving 320 respondents randomly selected from eight communities in each of Ijebu East Local Government Area (LGA) of Ogun State and Ife South Local Government Area (LGA) of Osun State was carried out using questionnaires. Data were collected on five top priority species including: bush mango (Irvingia gabonensis), African walnut (Plukenetia conophora), chewingstick (Massularia acuminata), fever-bark (Annickia chlorantha syn. Enantia chlorantha) and bush pepper (Piper guineense). Both descriptive and inferential statistics involving frequency tables, percentages, Likert scale, chi-square and multiple linear regression were used in analyzing the data at P = 0.05. Respondents’ sex, age, marital status, educational attainment and primary occupation had significant impacts on the level of consumption of P. conophora and A. chlorantha, while that of M. acuminata was significantly impacted by both marital status and household size. Primary occupation and age of respondents also significantly impacted the level of consumption of P. guineense, whereas only household size had a significant impact on the level of consumption of I. gabonensis. Products’ price, taste and substitute had no significant effect on _TFPs consumption. Although, each of the _TFPs has different socio-economic demand and niche among the consumers, the most determining factors of consumption were product availability and season of the year. The results of this study are valuable for predicting _TFPs consumption pattern and for policy orientation that targets sustainable use of the products
