A Review on the Geomaterial Aspects of Geothermal Reservoirs and Its Exploration

In this work a review on the geomaterial aspects of geothermal energy will be presented based on scholarly articles and published materials. As introduction an overview of basic geothermal resource concepts such as the occurrence of geothermal energy, mechanisms of heat flow in the ground and its reservoir types will be explained. Following this, properties of geothermal reservoir formations like permeability and thermal properties of rocks will be presented in detail. Geothermal resource and reservoir characteristics exploration methods including geophysical, geochemical and thermal gradient wells are also broadly discussed in this review. Moreover, a brief presentation on the geothermal resource and related research activities in Ethiopia will be addressed. The objective of this review is to discuss the role of geomaterials on the utilization of geothermal energy

The role of coffee based agroforestry system in tree diversity conservation in Eastern Uganda

Agroforestry farming system comprises considerable cultivated land area in the tropics. Despite the economic and social benefits of the system for farmers, it is also known to have an important role in the conservation of tree species. This study aims to evaluate the composition and distribution of tree species in coffee based agroforestry system to determine the potential for biodiversity conservation. To address the objective of this study, 57 sample plots in farmers’ coffee field and 12 sample plots in forest reserve were surveyed in Eastern Uganda. The result shows that the number of indigenous tree species in coffee farms was lower than that of forest reserve. Similarly, tree species richness per plot, Shannon and Simpson diversity indexes of forest reserve were significantly (p≤0.05) higher than that of coffee farms. However, with the inclusion of exotic tree species, coffee farms were found to be significantly higher than that of forest reserve for the above diversity indexes. On the other hand, the distribution of tree species in the coffee farms were mainly dominated by few tree species indicating the need for measures that ensure the sustainability of those less represented tree species

Exploring the potential of non-timber forest products: the case of Ethiopian honey export to Denmark

Its diverse agroecology has endowed Ethiopia with enormous honey production potential in Africa. Nevertheless, due to the undeveloped production system and poor market linkage with the global arena, the country could not fetch proportional benefits from this resource. To enhance better understanding on the problem and recommend appropriate improvement measures for the sector, prevailing opportunities and constraints were explored in relation to honey export to Denmark. Major honey stakeholders were contacted to assess the opportunities and constraints of Ethiopian honey export. Semi-structured interview, participatory appraisal technique and short questionnaire interview were adopted for data collection. The results show improving opportunities for exporting companies through creating conducive policy and support from the government of Ethiopia and NGOs. On the other hand, current supply of honey by producers in terms of quantity and quality are major constraints for the exporters. In relation to importer, there are growing demands for Ethiopian honey due to its organic source. Similarly, consumers. survey showed that the demand for organic honey has the highest priority in contrast to origin and price. However, most consumers lack information and have concern over Ethiopian honey; especially in terms of quality and characteristics. Development strategy that improves smallholder honey production capacity, better business communication with potential Danish honey importers and promotion of organic honey to consumers may make a significant contribution to enhance Ethiopian honey export to Denmark.Non-timber Forest Products; Ethiopia; honey; export; markets; Denmark
