The study was conducted on the islands of Lake Ziway, south-central Ethiopia. The aim of the study was to investigate the socio-economic factors affecting the vegetation resources and the indigenous resource management systems and practices on the islands. Data were collected by field observations, interviews and group discussion. The island communities were engaged in diverse economic activities. The fishing industry was the main pillar of the economy as most of the income (75.7%) was derived from this sector. The existence of diverse economic activities had relieved the pressure on the vegetation resources. The natural vegetation was the major source of fuelwood, construction material, farm implements, edible fruits, medicines, fodder and bee forage. The islanders have maintained the soil and vegetation resources for centuries through their environmental friendly resource management systems and practices. At present, however, the vegetation resources are dwindling due to free livestock grazing, farmland expansion, soil erosion and tree cutting for various purposes, all of which are driven by human population growth. Since the islanders have high respect and trust for the church, integrating environment and development issues with this institution would be more effective. The prevailing natural and anthropogenic factors affecting the vegetation resources on the islands necessitate effective conservation and management interventions.

Does Immigration Promote the Investment of the Monopolistic Firm?

In the present paper, we examine the effect of increasing uncertainty of immigrants’ growth on the optimal timing of investment of a firm that has a monopolistic power over the labor market. It is revealed that when the uncertainty of immigrants’ growth is more than a threshold level, increasing uncertainty of immigrants’ growth accelerates the optimal timing of firms’ investment and enhances the economic growth, even if the uncertainty of immigrants’ growth is formulated by the geometric Brownian motion, which is in sharp contrast to the standard result that an increase in the uncertainty postpones the optimal timing. With an increase in the immigrants over the past ten years, workforces in the host countries have been growing significantly to the extent that the immigrants represent 70% of the increase in the workforce in Europe, and 47% in the United States as OECD indicates. In the present paper, we attempted to investigate the effect of increased uncertainty caused by the growi...

Education Policy Implementation: A Mechanism for Enhancing Primary Education Development in Zanzibar

Education is one of the fundamental rights of individuals; therefore, the government of a country needs to develop and strengthen educational policy and quality as well as to ensure that everyone has equal access to basic education. The improvement of access and quality of education in the world is becoming as an essential factor in development, whereas the basic education (primary school), is acknowledged as a foundation of the higher educational development for every country. To fulfill this goal, governments introduce several policies and procedures; however, it requires some reforms and participation from the politician, policymakers, and other stakeholders to re-examine educational policy so that it can lead to multiplication and betterment of the reforms. Educational reforms actually focus on accountability. A positive educational development and reform is very challenging and needs more effort and strategy on how to use and utilize the resources effectively as such it can achie...
