“…The effect of conservation measures on SOC, SOM, and TN has been significant in the watershed. This coincides with Challa et al 2016 Sinore et al (2018), who reported statistically significantly higher SOC in terraced landscapes. It could be mainly related with conservation structures and biomass accumulation (Selassie et al 2015).…”

“…As a result, supporting SWC structures by agro-forestry practice has been suggested for better carbon sequestration in the soil (Abegaz et al 2016;Degefu et al 2011). Similarly, supporting terracing with susbania and elephant grasses could result in high SOC and SOM due to high biomass return, which contributes to symbiotic fixation and soil erosion reduction (Sinore et al 2018). However, we identified during on-site observation that as an agro-forestry and gully rehabilitation system, eucalyptus tree plantations were predominantly used to limit soil erosion and other related benefits in the study watershed.…”

“…The variation is primarily explained by conservation effects on soil erosion, because soil bund reduces loss of fine soil particles and residues (Husen et al 2017;Selassie et al 2015;Sinore et al 2018). This process further improves the concentration of SOM and SOC which consequently leads to increase TN in the soil.…”

Background: Soil erosion is among the foremost causes of declining soil resources in Ethiopia, which in turn affect agricultural productivity. To limit this problem, for the last two decades in Gumara watershed, soil and water conservation measures have been practiced through free labor community mass-mobilization. However, their effect on soil fertility has not been evaluated. This study investigated the impact of implemented soil and water conservation measures on fertility improvement in the Gumara watershed. Both composite and core soil samples were taken from upstream, midstream, and downstream adjacent conserved and non-conserved cultivated and grazing plots. Selected soil fertility indicators were analyzed using standard laboratory procedures. Results: Soil and water conservation practices have resulted in a statistically significantly higher mean values of total nitrogen, exchangeable Na + and Mg 2+ at p < 0.01, and of soil organic carbon and organic matter at p < 0.05 in the watershed. The clay content, soil reaction, cation exchange capacity, and exchangeable K + showed nonsignificant, but higher mean values in conserved plots. Furthermore, the effects of conservation practices on soil properties were found more effective in cultivated land uses as compared to that of grazing land uses. This is because conservation treatments had significant effects on organic carbon, total nitrogen, exchangeable Na + and Mg 2+ in cultivated land uses but only on exchangeable Na + in grazing land uses. The interaction effect of treatments and land uses did not reach a statistically significant result for any of the soil properties considered in this study. Conclusion: Conservation measures have important implications for improving soil fertility in the Gumara watershed. Therefore, proper guidance and follow-up, use of agro-forestry and grass strips, and maintenance are required for the watershed's sustainability and good soil conditions.

“…Because of this, smaller land and livestock holders use grass strips to stabilize soil bunds, minimize erosion and enhance soil productivity. This argues with the finding of Sinore et al (2018), who stated that land and livestock holding size has a strong association with farmer's perception on the uses of biological land management practices such as grass strips to minimize land degradation problems and enhances land productivity. This disagreement is arising due to the use of similar land management practice for lands under different conditions: already degraded land for restoration and stable cropland for maintaining productivity.…”

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.

“…Consequently, the country has been facing several environmental problems such as biodiversity loss, deforestation, flooding and food insecurity (CEPG, 2011). In return, the country is running various environmental management programs, for instance, environmental rehabilitation, participatory national resource management, watershed development programs, and environmental impact assessment (Bekele et al, 2018;Sinore et a., 2018). These interventions are executed with little scientific understanding and awareness of the community (Ruffeis et al, 2010).…”

Environmental knowledge and perceptions of community govern the sustainable use and management of environmental resources. 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 were 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 a 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 lacks of uniform environmental concept among community. 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) affected by age, childhood area, education and occupation when positively and significantly (P = .001) influenced by the origin of residence. Similarly, perception 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 the origin of residence and ethnic group. Generally, self-reported knowledge is not reliable source of information for environmental management decisions. So, stakeholders should strongly work on environmental awareness campaigns, engage students in outdoor activities, and training to improve factors negatively determined community's factual knowledge and perception of the environment.
