Abstract

Soil degradation is the major environmental and agricultural production problem in the highlands of Ethiopia. The objectives of the study were to examine farmers’ use of grass strip and soil bund to minimize soil degradation, and effects of grass strip and soil bund on basic soil properties.  Structured questionnaire survey and field observations were conducted to collect data on farmers’ use of grass strips and soil bund to minimize soil erosion, improve soil fertility and crop productivity. Simultaneously, composite soil samples were collected from croplands treated with both grass strip and soil bund, and the adjacent lands treated with soil bund only. The statistical result indicates respondents sex, marital status, educational level, erosion degree, access to conservation information, contact with extension workers, and trainings were significantly (P < 0.05) and positively affect the use of  grass strips while livestock and land holding sizes were significantly (P < 0.05) and negatively affect farmers use of grass strip. The interaction of land management practices (grass strip and soil bund) and slope positions was significantly (P < 0.05) affects soil clay fractions and moisture, the highest amounts was observed at lands managed with grass strip situate at lower slope position. Similarly, soil organic matter, total nitrogen, available phosphorus, and cation exchange capacity were significantly (P < 0.05) influenced by the combined effects of land management practices and slope positions, highest quantity of these properties were observed lands managed with a grass strip and soil bund in lower slope position. Hence, integrated use of soil bund with grass strip has a meaningful contribution for selected soil property improvement that enhances soil fertility and crop productivity.

Abstract

Environmental knowledge and perceptions of community govern the sustainable use and management of environmental resources. Developing countries such as Ethiopia has been facing serious environmental problems. In spite of the existing problems, little is known about public understanding and perception of environmental issues. Thus, the overall objective of this research was to assess community perception and knowledge of environmental issues. Interview was conducted using structured questionnaire. The collected data was coded, cleaned and analyzed using descriptive and inferential statistics. The result indicates, most of the community members believed that they have better knowledge of environmental issues but the evidence obtained from measured knowledge shows the reverse. The principal source of environmental information (local media broadcasting) had positive correlation with perceived knowledge, and negatively correlated with assessed knowledge and perception index of environmental issues. Correctly answered questions used in the evaluation of environmental knowledge were weekly associated (r < .2) with perceived knowledge and perception, which indicates the respondents lacks same concept on environmental issues. Perceived knowledge was negatively and significantly (P <.001) determined by age and educational levels of respondents. But, measured knowledge was negatively and significantly (P <.05) affects by age, childhood area, education and occupation when positively and significantly (P = .001) influenced by origin of residence. The perception of community was positively and significantly (P =.001) determined by respondent's age, childhood area, education and information source but negatively and significantly (P < .05) influenced by origin of residence and ethnic group. Generally, self-reported knowledge is not reliable source of information for environmental management decisions. So, stakeholders should strongly works on environmental awareness campaigns, engage students in outdoor activities, and training to improve factors negatively determined community's factual knowledge and perception of environment.Â
