The universal soil loss equation (USLE) used to estimate potential soil erosion. Data on local community perception obtained from a survey of 62 farm households and five local experts. In-depth interview, group discussion and non-participant field observation also carried out to obtain additional information. The USLE results agreed with the farmers’ (67%) and local experts’ opinion that erosion at study area is severe and affects the quality of lives of residents. Insignificant difference (p > 0.05) was observed in the estimated soil loss among treatments. However, the estimated soil loss from free grazing lands was higher by 47% than soil loss from exclosures which illustrated that exclosures are effective to control soil erosion. The majority of farmers (70%) also rated exclosures effectiveness to control soil erosion as high. Local communities were optimistic about the chances to rehabilitate degraded lands and make them productive. The majority of farmers (60%) did not consider population growth as a cause of soil erosion. For the majority of interviewed farmers, poor land management is more important. Efforts to create awareness within the rural communities should focus on the link between high population growth, environmental degradation and poverty. The optimistic view of local communities can be considered as an asset for the planning and development of degraded lands rehabilitation efforts."],["dc.identifier.fs","388891"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/5856"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/61203"],["dc.language.iso","en"],["dc.notes.intern","Merged from goescholar"],["dc.relation.orgunit","Fakultät für Forstwissenschaften und Waldökologie"],["dc.rights","Goescholar"],["dc.rights.uri","https://goescholar.uni-goettingen.de/licenses"],["dc.subject.ddc","570"],["dc.title","Effectiveness of exclosures to control soil erosion and local community perception on soil erosion in Tigray, Ethiopia"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

It is generally assumed that exclosures lead to restoration of natural resources such as soil fertility, vegetation biomass and composition, fauna, and water storage; however, this is not supported by studies. In the present study, our objective was to assess the impact of exclosures on soil properties, and relate the age of exclosures to their effectiveness in improving soil chemical and physical properties. Five and ten years closed areas had significantly (po0:05) higher levels for soil organic matter, total nitrogen, and available phosphorus compared to free grazing lands, and the highest levels in were observed in closed areas at footslope position. Our results show that exclosures are not only effective in restoring vegetation, but also in improving soil nutrient status, and reducing erosion. From a technical point of view, it is therefore recommendable to convert grazing areas into exclosures. However, implementing exclosures leads to an even smaller communal area left for grazing and the socio-economic consequences of this should also be considered. r 2006 Elsevier Ltd.

In this study, we investigated changes in ecosystem C stocks (ECS) after establishing exclosures on degraded communal grazing lands, and identified easily measurable biophysical and management-related factors that can be used to predict ECS restoration in the highlands of Tigray, Ethiopia. We selected replicated (n = 3) 5-, 10-, 15-, and 20-yr-old exclosures and paired each exclosure with an adjacent communal grazing land. All exclosures displayed higher ECS than the communal grazing lands. Differences in ECS between exclosures and grazing lands varied between 29 (±4.9) and 61 (±6.7) Mg C ha−1 and increased with exclosure duration. In exclosures, much of the variability in ECS was explained by a combination of the following variables: precipitation, clay content, vegetation canopy cover, woody biomass, and exclosure duration (R 2 = 0.77–0.90). Precipitation and vegetation canopy cover also explained much of the variability of ECS in communal grazing lands (R 2 = 0.48–0.55). Our results help to establish baseline information for C sequestration projects and to predict the expected ecosystem C sequestration under exclosures. Expansion of exclosures would increase grazing pressure on the remaining communal grazing area. Therefore, the decision to establish additional exclosures should also include an economic analysis and an evaluation of the social consequences."],["dc.identifier.doi","10.2136/sssaj2010.0176"],["dc.identifier.gro","3150137"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/6868"],["dc.language.iso","en"],["dc.notes.status","public"],["dc.relation.issn","1435-0661"],["dc.title","Restoration of Ecosystem Carbon Stocks Following Exclosure Establishment in Communal Grazing Lands in Tigray, Ethiopia"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dc.type.peerReviewed","no"],["dspace.entity.type","Publication"]]
