Human impact on the environment in the Ethiopian and Eritrean highlands—a state of the art
Abstract This review analyses the environmental evolution of the Ethiopian highlands in the late Quaternary. The late Pleistocene (20,000–12,000 14C years BP) was cold and dry, with (1) low lakeExpand

Effectiveness of exclosures to restore degraded soils as a result of overgrazing in Tigray, Ethiopia
As a response to land degradation in Tigray, Northern Ethiopia, regional authorities have promoted rehabilitation of degraded lands through closed areas since 1991. It is generally assumed thatExpand

Runoff on slopes with restoring vegetation: A case study from the Tigray highlands, Ethiopia
Daily runoff depths from 28 plots (5 m x 2 m) recorded during a 2-year period in the semi-arid to subhumid highlands of Tigray were analyzed to study the effect of vegetation restoration inExpand

Interdisciplinary on-site evaluation of stone bunds to control soil erosion on cropland in Northern Ethiopia
Since two decades, stone bunds have been installed in large areas of the Tigray Highlands, Northern Ethiopia, to control soil erosion by water. Field studies were conducted to quantify theExpand

The demand for a malaria vaccine: evidence from Ethiopia
This study measures the monetary value households place on preventing malaria in Tigray, Ethiopia. We estimate a household demand function for a hypothetical malaria vaccine and compute the value ofExpand

Sediment deposition and pedogenesis in exclosures in the Tigray highlands, Ethiopia
In the Tigray highlands of Northern Ethiopia, the establishment of exclosures (i.e., areas closed for grazing and agriculture) has become an important measure to combat land degradation and restoreExpand

Rainfall erosivity and variability in the Northern Ethiopian Highlands
The Ethiopian Highlands are subjected to important land degradation. Though spatial variability of rain depth is important, even at the catchment scale, this variability has never been studied. InExpand

Impact of road building on gully erosion risk: A case study from the northern Ethiopian Highlands
Although obvious in the field, the impact of road building on hydrology and gullying in Ethiopia has rarely been analysed. This study investigates how road building in the Ethiopian Highlands affectsExpand

Tillage erosion on slopes with soil conservation structures in the Ethiopian highlands
Abstract Soil translocation due to tillage by the ox-drawn ard plough appears to be an important source of colluviation behind stone bunds and lynchets in the Ethiopian highlands. To quantify erosionExpand

Stone bunds for soil conservation in the northern Ethiopian highlands: Impacts on soil fertility and crop yield
Abstract In the Ethiopian highlands, large-scale stone bund building programs are implemented to curb severe soil erosion. Development of soil fertility gradients is often mentioned as the majorExpand
