“…Subsets of the same dataset of repeated photographs have been used in qualitative and semi-quantitative analyses of changes in land use and management between two moments in time (Crummey, 1998;Hurni, 2005;Munro et al, 2008;Nyssen et al, 2009), to map historical land uses in periods before the existence of aerial photography (Meire et al, 2013), to analyze climate-induced changes to the upper treeline (Nievergelt, 1998), to calibrate the categorization of historical land uses as derived from satellite imagery (de Mûelenaere et al, 2013), or to study gully development (Frankl et al, 2011 2011 photographs were assigned a "zero" value (against which the older photographs were evaluated).…”

As quantitative or spatially distributed studies of environmental change over truly long-term periods of more than 100 years are extremely rare, we re-photographed 361 landscapes that appear on historical photographs (1868-1994) within a 40,000 km² study area in northern Ethiopia. Visible evidence of environmental changes apparent from the paired photographs was analyzed using an expert rating system. The conditions of the woody vegetation, soil and water conservation structures and land management were worse in the earlier periods compared to their present conditions. The cover by indigenous trees is a notable exception: it peaked in the 1930s, declined afterwards and then achieved a second peak in the early 21 st century. Particularly in areas with greater population densities, there has been a significant increase in woody vegetation and soil and water conservation structures over the course of the study period. We conclude that except for an apparent upward movement of the upper tree limit, the direct human impacts on the environment are overriding the effects of climate change in the north Ethiopian highlands and that the northern Ethiopian highlands are currently greener than at any other time in the last 145 years.

“…Several studies have analyzed land use change in the Tigray region (Meire et al 2012;Kassa 2013). Belay et al 2014 analyzed land use and land cover changes in Tigray from 1965 to 1994 and 2007.…”

“…The De'sa natural forest in western Tigray is suffering from settlement by migrants and from woodcutting for the production of charcoal. Meire et al (2012) used remote sensing data to analyze land use change in northern Ethiopia over the past 140 years and found improvements in woody vegetation and development. The authors conclude that improved land and water management in northern Ethiopia has led to environmental rehabilitation.…”

Drylands-defined here to include arid, semi-arid, and dry sub-humid zonesare at the core of Africa's development challenge. Drylands make up 43 percent of the region's land surface, account for 75 percent of the area used for agriculture, and are home to 50 percent of the population, including a disproportionate share of the poor. Due to complex factors, the economic, social, political, and environmental vulnerability in Africa's drylands is high and rising, jeopardizing the long-term livelihood prospects for hundreds of millions of people. Climate change, which is expected to increase the frequency and severity of extreme weather events, will ...

“…The bench terrace 'kaha' by the Konso people, 'daldal' dams to trap silt water by Irob-Tigre people and Gedeo's agroforestry systems are best among the important attributes of indigenous practice in agricultural development in Ethiopia (Meire et al, 2012;Mitiku et al, 2006;Tesfaye, 2005). The Konso SWC terraces are internationally recognized and registered by UNESCO.…”
