Different research strategies were employed to answer the research questions, which include; desk study, interview, focus group discussion, field survey and observation were employed to collect pertinent information on the pre-harvest and post-harvest factors within the value chain. Data were collected and analyzed by different methods to identify which practices were the possible factors deteriorating the quality of the coffee in the value chain. The result indicated that, at the pre-harvest level, inadequate use of fertilizers, limited moisture, lack of practicing rejuvenation and pruning, coffee wilt and berry diseases, insect pest incidence were the main factors to deteriorate the quality coffee production. At the post-harvest level, carrying out of improper harvesting practices, hardly use of recommended packaging materials...

Stratospheric sulfate aerosols can form from sulfur dioxide that has been transported from the underlying troposphere. Large volcanic eruptions can inject sulfur dioxide and other material into the stratosphere, but smaller volcanoes have been thought not to be energetic enough to do so. Bourassa et al. (p. 78 ) used satellite data to show that sulfur dioxide from the 2011 eruption of the Nabro stratovolcano in Eritrea was lofted into the stratosphere by deep convection associated with the Asian summer monsoon.
