Several studies have shown the environmental and health impacts of emission of criteria air pollutants such as SO2, NOx, PM, and VOCs. These pollutants are primarily associated with acid rain, ground level ozone or smog, and formation of inhalable particulate. The present study will examine...

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...

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...

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...

Radical changes took place with respect to several agricultural policies in Ethiopia in 1990-91. Different agricultural technologies were being delivered by several international agencies. Shifts in government policies and technological intervention would induce changes in the production...

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...

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...

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...

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...

Electric and natural gas are the two major sources of energy for residents of Washington State. Several states have adopted a policy whereby utility companies decide on the choice of mixes of resources by incorporating cost effectiveness, conservation and externalities. Externalities could...
