Stochastic frontier production function analysis was performed to examine relative crop and milk production efficiency among peasants in Ada and Selale districts of the Central highlands of Ethiopia. The results indicate that Ada farmers exhibit relatively higher efficiency scores in cereal...

Physical resources such as land, labour and livestock, and nonphysical resources such as indigenous knowledge and institutions of producers in the grain surplus and deficit regions of the Central Highlands of Ethiopia are examined under situation of environmental and policy risks. Frequency...

Agricultural information and indigenous knowledge were examined among peasants of the central Ethiopian highlands. Measures of central tendency, logical explanation, descriptive analysis, problem solving tests, scoring and logit analysis were performed. The findings indicate that information...

The study examined a simplified conceptual model which incorporates variables that influence the processes and consequences of household decision-making in the Ada and Selale districts of the Ethiopian highlands. Linear structural relations (LISREL) analysis was performed on three conceptual...

Multidisciplinary research methods such as observatory, participatory and multivariate regression analysis were employed to examine goals and strategies of two peasant communities in the Central highlands of Ethiopia. Continuing the family tradition of participating in social networks is found...

Descriptive and logit analysis were employed to investigate the impact of social, economic and technical factors on decisions to adopt new agricultural technologies in the Ada and Selale districts of Ethiopia. Peasants follow sequential adoption of technologies. In both study areas, priority is...

An aggregate measure of production efficiency involving crop and livestock enterprises is examined in the Selale and Ada regions of Ethiopia using Data Envelopment Analysis (DEA). In general, farmers in regions more suitable to crop production (Ada) tend to attain higher production efficiency...

In the past environmental management practices have been based on disparate analysis of the impacts of pollutants on selected components of ecosystems. However, holistic analysis of emission reduction strategies is necessary to justify that actions taken to protect the environment would not...

The 1990 Canadian long-range transport of air pollutants and acid deposition report divided North America into 40 sources of emission and 15 sensitive receptor sites. For the purpose of national policy making and international negotiation, the use of these large sources and few receptors may...

There is a disagreement on the concept, definition and application of the paradigm of sustainable development. The definition that has been accepted by many involves several components, and it is difficult to measure or quantify indicators. Depending on the structure of the economy, it is...
