Abstract:

For societies that depend on agriculture, the process of meeting current or future welfare demands should not continue without regard to the potential long-term dangers of land resource over-use. With an increasing human and animal population in the Ethiopian highlands development efforts so far have been hasty and disjointed, and have sidetracked issues of production base security and conservation. As a result, large-scale degradation has ensued, and if the trend continues the agricultural future of the country is threatened. Cohesive land-use practices are needed in order to manage the fragi

Abstract:

Geoheritage conservation in Ethiopia: the case of the Simien Mountains Ethiopia constitutes one of the most significant environmental and cultural reserves on Earth. Ethiopia's natural and cultural tourist attractions are mostly associated with geological features: the active Ethiopian and Afar rifts as well as the Simien and Bale massifs are few examples. Ethiopia's cultural history, religious manifestations and civilization, like the rock-hewn churches of Lalibela and the stelae of Axum, are also imprinted in rock.

AbstractThis study compares different methods of predicting crop-related climate in the Ethiopian highlands for the period 1979–2009. A target index (ETH4) is developed as an average of four variables in the June–September season—rainfall, rainfall minus evaporation, estimated latent heat flux, and vegetation, following correlation with crop yields at Melkassa, Ethiopia (8.4°N, 39.3°E, 1550 m elevation). Predictors are drawn from gridded near-global fields of surface temperature, surface air pressure, and 200-hPa zonal wind in the preceding December–March season. Prediction algorithms are form

Abstract:

Recent work using observational data from the International Satellite Cloud Climatology Project (ISCCP) and reanalysis products suggests that African easterly waves (AEWs) form in association with a “transition” process from smaller and scattered convection into larger and organized mesoscale convective activity. However, the transition process is unclear and how mesoscale convection initiates AEWs is not well understood. Analysis based on 25 years of ISCCP and reanalysis datasets show that increasing intradiurnal activity, atmospheric instability, and specific humidity precede the development

The freshwaters of the East African nation of Ethiopia are divided into nine main drainage basins.

Despite some development activities, including proposed dam construction with potential impacts on ichthyofaunal diversity, the Ethiopian part of the basin generally lacks comprehensive study or full scientific documentation.

Downscaling of seasonal hindcasts over East Africa with the regional climate model (RCM) COSMO-CLM (CCLM), forced by the global climate model (GCM) and MPI-ESM, is evaluated.

The dry years, 2002 and 2009, and the wet years, 2006 and 2007, are well captured by the models. By using ground based and satellite gridded observation data for evaluation it is found that both COSMO-CLM and MPI-ESM overestimate June to September precipitation over the E

Today it survives in only six locations, with the largest and probably only genetically viable population being found in the Bale Mountains National Park.

Soil erosion in Ethiopian highlands has caused land deterioration due to moving nutrient-rich top soil to downstream reservoirs while leaving reservoirs dysfunctional due to sedimentation. Micro-watershed management by removing reservoir sediments and using them for reclaiming farmland, while using reservoir water for irrigation, can be a potential solution to simultaneously address soil and water constraints and food security challenges. Still, there is knowledge gap before such a solution can be practically applied. The objective of this paper is to present potential solutions for the reserv

A better understanding of malaria persistence in highly seasonal environments such as highlands and desert fringes requires identifying the factors behind the spatial reservoir of the pathogen in the low season. In these ‘unstable’ malaria regions, such reservoirs play a critical role by allowing persistence during the low transmission season and therefore, between seasonal outbreaks. In the highlands of East Africa, the most populated epidemic regions in Africa, temperature is expected to be intimately connected to where in space the disease is able to persist because of pronounced altitudina

Traditional crops are grown on residual moisture late in the season (September–January) when waterlogging is less of a problem. Productivity is therefore below its potential. The recent introduction of a broadbed and furrow system for improved drainage on Vertisols allows full use of the growing period and provides scope for a wider variety of cropping systems and increased productivity.

Abstract:

The tadpole of poorly studied Leptopelisragazzii (Boulenger, 1896), a high-altitude tree frog species from the Ethiopian highlands, is described for the first time and compared with closely related sympatric species – L.gramineus (Boulenger, 1898) and L.vannutellii (Boulenger, 1898).

Abstract:

AbstractAlthough conversion is one of the major themes in the religious and cultural history of Ethiopia, it has yet to benefit from extensive and systematic comparative discussion. For generations, scholars have worked to deepen our understanding of conversion to both Orthodox Christianity and Islam in the Ethiopian highlands. Recent works, moreover, are noteworthy for their efforts to expand our knowledge of both regions and groups hitherto neglected. Modern Islam, Evangelical Christianity and the religious histories of the peoples of Southern Ethiopia are only a few of the topics that have

Abstract:

Soil spectroscopy was applied for predicting soil organic carbon (SOC) in the highlands of Ethiopia. Soil samples were acquired from Ethiopia’s National Soil Testing Centre and direct field sampling. The reflectance of samples was measured using a FieldSpec 3 diffuse reflectance spectrometer. Outliers and sample relation were evaluated using principal component analysis (PCA) and models were developed through partial least square regression (PLSR). For nine watersheds sampled, 20% of the samples were set aside to test prediction and 80% were used to develop calibration models. Depending on the

Abstract:

Rain-fed agriculture in North-West (NW) Ethiopia is seasonally modulated, and our objective is to isolate past and future trends that influence crop growth. Statistical methods are applied to gauge-interpolated, reanalysis, and satellite data to evaluate changes in the annual cycle and long-term trends. The June to September wet season has lengthened due to the earlier arrival and later departure of rains. Meteorological composites relate this spreading to local southerly winds and a dry-south/wet-north humidity dipole. At the regional scale, an axis of convection over the Rift Valley (35E) is

Abstract:

AbstractIn this study we model the preferences and willingness to pay (WTP) of downstream farmers in one of the largest irrigation schemes worldwide in Sudan for improved irrigation water supply through transboundary collaboration with farmers upstream in Ethiopia. In a choice experiment, Sudanese farmers are asked to pay an increase in existing irrigation fees to secure future irrigation water availability by either enhancing the removal of sediments in their local irrigation channels or compensating farmers in the Ethiopian highlands for taking soil conservation measures to prevent land degr

Abstract:

AbstractLittle information is known about the influence of altitude on child growth in Ethiopia, where most people live in highlands. We investigated the relation of residential altitude with growth faltering (stunting) of infants and young children in Ethiopia. We also examined whether the altitude–growth relationship was independent of the influence of the dietary and non-dietary determinants of growth. We used the data of 26 976 under-5-year-old children included in the Ethiopian Demographic and Health Surveys, conducted from 2005 to 2016. The samples were recruited following a two-stage cl
