Furthermore, the authors indirectly determined the involvement of farmers in charcoal production in Atwima Mponua District of Ghana. A total of 120 producers were interviewed and simple ranking was used for the analysis. Twenty-three plant species were used with the first, second, third and fourth which were Celtis mildbraediL Cylicodiscus gabunensis, Margaritoria discoides and Amphimas pterocarpoides respectively. However, the Amphimas pterocarpoides was not among the traditional charcoal-producing species. The wood used came from seven different sources. None of the charcoal producers had a plantation of charcoal-producing species. Only 13 % of the producers were willing to plant, 87% of them who were not willing to plant indicated that they would leave charcoal production if the resource got finished. The 120 charcoal producers were made up roughly of 56% males, and 44% females and in which 69.2% of them were farmers.展开更多

Secondary school managers have the gigantic task of balancing meager resources between subsistence and development needs as well as good performance in national examinations. However, macro-economic shocks such as inflation, fuel shortage, and crop failure, among others, often militate against the success of public schools. School-based IGAs enable public schools to cope with external economic shocks, without necessarily passing down budgetary adjustments to parents. However, the country lacks a clear policy guideline to facilitate the initiation, management, accounting, reviewing, and financial reporting of IGA projects. Besides, there is no documented information regarding the value added by IGA initiatives to the financial performance of public secondary schools. The study found that IGA and non-IGA schools were significantly different in terms of category, student population, age, annual income, and number of paid workers. Schools having IGAs were 1.9 times more likely to own as many assets as schools not having IGAs. Besides, IGA schools were about 2.2 times less likely to have their liability in excess of the median threshold. Regarding net worth, the study found that schools having IGAs were about 2.1 times more likely to be operating above the median threshold; suggesting that schools having IGAs were wealthier than non-IGA schools. Based on the findings, this study concludes that IGA projects were beneficial to schools by improving the ability of schools to accumulate assets and manage their liabilities. The study recommends the need to： formulate an appropriate policy framework to guide and standardize IGA activities; initiate suitable training programs for school IGA managers; as well as engage business development managers to advice schools on IGA matters.展开更多

Cross-sectional survey research design was applied for collecting quantitative data using a semi-structured questionnaire administered to 384 households stratified on the basis of PFM participation status. Qualitative data was collected through focused group discussions using a checklist and key informant interviews using an interview schedule. Using Statistical Package for Social Sciences version 25, Binomial regression with Wald Chi-square was analyzed to identify factors perceived to be significantly influencing benefits for PFM participants and Pearson Chi-square to compare factors perceived to be affecting PFM and non-PFM participants. CFA members participation in PFM was significantly and positively affected by benefits of PFM income generating activities and forest products accessed in the forest. Benefits linked to Plantation Establishment for Livelihood Improvement System (PELIS) for CFA members were significantly reduced by enforcement of moratorium policy since February 2018, diseases and pests, poor PELIS guideline adherence and animal damage. Benefits related to state forest access for firewood by the CFA members were negatively influenced by the moratorium policy. Diseases and pests affected benefits associated with bee keeping significantly. Comparing factors under different PFM participation status, crop production was significantly affected by policy changes, pest and diseases, animal damage and PELIS guideline adherence for CFA members than for Non-CFA members. Policy changes also affected the CFA members significantly in firewood collection and access to fodder in the state forest than the Non-CFA members. Hence, sustainable community participation in Upper Imenti Forest management requires: incr展开更多
