The land-use change from agroforestry (AF) to monoculture-based agriculture has the potential to change soil microbial biomass carbon (MBC). The MBC has been used as an indicator of soil quality as well as to determine the microbial status of soil. The aim of this study was to analyze the distribution of soil MBC across different agroforestry pract...

More than 90% of rainfed croplands in Sub-Saharan Africa (SSA) are severely affected by highly intermittent rainfall and frequent drought limiting crop productivity in the region. Besides, 27.1% of the population in SSA are currently food insecure and this is likely to increase with the current rapid population growth in the region. Soil erosion an...

The survival and growth performance of tree seedlings in degraded drylands can be improved by applying moisture and fertility-enhancing management interventions. This study evaluated the survival and growth responses of Acacia decurrens seedlings to different management practices, pit sizes, and niches in Tigray, Ethiopia. A factorial experiment wa...

In recent years, armed conflicts are globally on the rise, causing drastic human and environmental harm. The Tigray war is one of the recent violent conflicts that has abruptly reversed decades of ecosystem restoration efforts. Although field-based investigation into the level of damage is complicated by access and safety issues, recent advances in...

Anthropogenic disturbance put the woodlands in the monasteries and churches under signi cant threat. To study the oristic composition and forest degradation of Waldiba monastery dry woodland in Tigrai, Ethiopia, 30 plots were established along transect lines. We recorded 39 native woody species (33 trees, 5 shrubs and 1 liana) belonging to 19 famil...

Increased in soil total nitrogen (TN) as influenced by Faidherbia albida here after F. albida have been explored for decades. However, changes in ammonium (NH ) to nitrate (NO ) ratios as influenced by the tree and the relationships with other soil physicochemical and biological properties were not explored. Thus, the present study was carried out...

Background: A range of local social and environmental factors has an impact on farmers' views of climate change and choices on the use of coping mechanisms. This study examines the factors that are limiting farmers' perceptions of climate change and their coping mechanisms in Gimbi district, Western Ethiopia. Methods: A household survey and focus g...

Agroforestry systems are thought to reconcile biodiversity protection with food production and as a means of climate change adaptation and mitigation options. The contribution of a coffee-based agroforestry system to tree diversity and carbon stock along altitudinal gradients in Western Ethiopia was assessed. At 500-m intervals, six transect lines...

The study was conducted in the Harego dry Afromontane forest, Northeastern Ethiopia, to analyze woody species composition, diversity, structure, and regeneration status. To collect the vegetation data, a total of 67 sample plots measuring 400 m 2 20 m × 20 m were laid systematically. Species identity, abundance, height, and diameter at breast heigh...

Background Land use, land cover change has been known globally as an essential driver of environmental change. The study focuses on modeling and prediction of land use, land cover using land change modeler in Suluh river basin. Landsat images and other ancillary data sources were used to achieve the objectives. Nearest neighbor fuzzy classification...

The study focuses on modeling and prediction of land use/land cover using land change modeler in the Suluh river basin. Landsat images and other ancillary data sources were used to achieve the objectives. The nearest neighbor fuzzy classif...

Agroforestry practices that integrate trees into farming are known to enhance carbon sequestration and plant species diversity in agricultural landscapes. Their contribution however, varies depending on a number of factors including elevation gradients. In this study, we quantified the carbon (C) stock and woody species diversity in tree-ensete dom...

Dry Afromontane forests form the largest part of the existing natural vegetation in Ethiopia. Nevertheless, models for quantifying aboveground tree biomass (AGB) of these forests are rare. The objective of this study was, therefore, to develop local multispecies and species-specific AGB models for dry Afromontane forests in northern Ethiopia and to...

Despite their importance as sources of ecosystem services supporting the livelihoods of millions of people, forest ecosystems have been changing into other land use systems over the past decades across the world. While forest cover change dynamics have been widely documented in various ecological systems, how these changes affect ecosystem service...

Exclosures are used to regenerate native vegetation as a way to reduce soil erosion, increase rain water infiltration and provide fodder and woody biomass in degraded grazing lands. Therefore, this study assessed the impact of grazing exclosure on vegetation biomass, carbon sequestration and soil nutrients under five and ten years of grazing exclosu...

Ziziphus spina-christi is a multipurpose drought tolerant tree or shrub and is commonly used in the parkland agroforestry system in Sub-Saharan Africa. The study determined the effect of Ziziphus spina-christi on soil physicochemical properties, its foliar nutrient content as animal fodder and its contribution to household income. Soil physical and...

This research was conducted in Kafta-Humera districts of the Northern Ethiopia with the objective to determine the effect of human settlement on rangeland productivity and biodiversity under three altitudinal ranges (600-1000, >1000-1400 and >1400-1800 m.a.s.l.) and along three distance intervals near (0-2 km), middle (2-4 km) and far (4-6 km) from...

A research was conducted in Kafta-Humera districts of the Northern Ethiopia with the objective to determine the effect of human settlement on rangeland wood species productivity and biodiversity under three altitudinal ranges (600-1000, >1000-1400 and >1400-1800 m.a.s.l.) and along three distance intervals near (0-2 km), middle (2-4 km) and far (4-...
