This paper assesses the contribution of ecotourism to local communities and the environment.Livelihoods of local communities are examined to understand the socioeconomic situation of people living in proximity to ecotourism areas and their participation in ecotourism activities. The impact of ecotourism on the environment in Nyanga is also examined. The paper employs both literature review(secondary data) and a field survey(primary data) to achieve these objectives. To gather socioeconomic data of households and tourist traits, questionnaires were administered to120 households and 30 tourists in the study area. Key informant interviews were held in the survey to gather expert knowledge about ecotourism trends and environmental data in the area.Data were analyzed using Statistical Package for Social Sciences. Descriptive and inferential analyses were used for quantitative data while content and structural-functional analyses were used for qualitative data. The research revealed that ecotourism offers the highest salaries when compared to other sources of formal employment. Ecotourism activities were shown to positively impact the environment through the protection, preservation, and management of natural resources. The study concludes that ecotourism is a useful and sustainable poverty alleviation strategy which has not yet been fully exploited in Zimbabwe. 展开更多

The paper sought to explore issues of access, equity, and quality in the early childhood development (ECD) sub-sector in Zimbabwe. The massive expansion of ECD services prompted the author to undertake the study. Data were collected using focus group discussions, individual interviews, document analysis, and observations. Information from literature, research reports, policies, and practices was also analyzed in order to establish the state of affairs in the provision of ECD. The data were analyzed using theme identification methods to solicit emerging issues. Generally, it was found that on issues of access, equity, and quality in ECD in Zimbabwe, there is a quality-quantity dilemma with qualitative progress less conspicuous than quantitative progress. The resultant specific challenges include: large teacher-child ratio; lack of parental involvement, lack of trained ECD specialists with expertise in using a play-based curriculum; and shortage of equipment, material resources, and age appropriate infrastructure. In most ECD settings, there were inadequate health and nutrition provisions. Water, sanitation and health (WASH) facilities were found to be insufficient in most centres. The study recommended that there is need for: equal access to quality early childhood education; provision of infrastructure, provision of ability and age appropriate resources; and health, sanitation, and nutrition services especially in rural settings. Overall, ECD programmes in Zimbabwe should strive to attain quality more than quantity services. The need to train more early childhood specialists who would drive the ECD sub-sector is emphasized. 展开更多
