In the highland areas of Ethiopia, farming communities are struggling with severe soil erosion, which is putting significant strain on ecosystems and food production capabilities. Many smallholder farmers in the basin cultivate fragile soils on steep slopes, often without proper management practices, leading to substantial soil loss, ecosystem degr...

The upper Tekeze River Basin is facing challenges of widespread deforestation and natural vegetation cover degradation that could exacerbate the water scarcity, food insecurity and extreme poverty in the region. Using remote sensing and GIS, this study quantified the land use land cover change trend in the last three decades and analyzed the curren...

Watershed reactions to environmental changes is critical for water resource use and management planning. The change in land use/land cover (LUCC) alters surface water hydrology and water balance, subsequently it affects the availability of water resources. This study examined Akaki River catchment surface hydrological responses to future land use s...

Assessment of the change in ecosystem services and their bundles and hotspots in a spatial-explicitly manner can provide practical support for ecological conservation measure priority setting. This study assessed the spatio-temporal dynamics of vital ecosystem services (ESs) from 1972 to 2047 and identified statistically significant hotspots and co...

Landscape pattern changes are mostly due to human activities, and such changes often affect ecosystem functions and services. This study was conducted to evaluate the response of hydrological ecosystem services (HESs) to structural landscape changes. Spatiotemporal changes in two specific HES indicators, water yield (WY) and sediment export (SE), w...

An increase in human population generally exerts pressure on natural habitats and leads to a decline in biodiversity resources. As a proxy for biodiversity study, an evaluation of habitat quality (HQ) change caused by land use/land cover (LULC) and associated landscape structural changes may provide a scientific basis for ecological protection and...

Analyzing long-term dynamics of landscape patterns can provide important insights into the changes in landscape functions, that are necessary for optimizing resource management strategies. This study primarily aimed at quantifying landscape structural change. The Land use/land cover (LULC) layers of 1972, 1987, 2002, and 2017 were mapped from Lands...

Land evaluation is the core component of land-use planning process, particularly where resource is limited and degraded, like Ethiopian Highland. Thus, evaluation of land in terms of its capability is important. The aim of land capability is to identify the physical inherent capacity of the land for different uses to avoid further degradation. Rele...

Land evaluation is a foundation for sustainable land resource planning and management. In Ethiopia, national economic development is highly dependent on agriculture. And, the productivity of the land is low as a result of land degradation due to mismanagement of the land and intensive cultivation; this situation is worse in Ethiopian Highlands like...

Currently ecosystem degradation is become the main challenges of human being. Conservation of resource and traditional restoration is not sufficient because of high consumption rate and limited resource left on the earth. Consequently, Ecological restoration become the prime option. It is scientific application of restoration ecology and deals with...

Land use and land cover (LULC) dynamics have been among the most important visible changes that have taken place everywhere in the Ethiopian landscape. Such changes are severely affecting ecosystem health including degradation of nature reserves and wild animal sanctuaries. One such nature reserve in Ethiopia is the Abijata-Shala National Park (ASN...

This work focuses on intensive review of various documents, research papers and reports to identify the main source; impact and trend of river and water reservoirs pollution in and around Addis Ababa city, the capital city of Ethiopia. Water is a vital resource needed for the survival of humans and cities. Ethiopia is often referred to as the “wate...

This paper emphasize on intensive desk review by using data from research articles, books, reports and different documents to explore best case studies for different environmental management strategies and observe the link of these strategies with pollution prevention hierarchy. Environmental management evolves through a serious of strategies start...

Global forests are extremely diverse and provide a variety of ecosystem services including carbon sequestration. Large trees are the most effective organisms to stock atmospheric carbon. Ethiopia has substantial forest resource cover. But there is still limitation of scientific studies that magnify the role of forests for climate change mitigati...

Forests provide important ecological and environmental benefits. They serve as natural sinker of atmospheric CO 2 to mitigate climate change. In Ethiopia although, there is significant forest resource, the studies on carbon stock potential and factors that affect this potential have not been well studied. This study was done with the aim of estimat...

Forests are known to play an important role in regulating the global climate. Ethiopia has a substantial forest resource; however, these forests are facing a rapid rate of deforestation and degradation. This in turn adversely affects forest carbon stock under studied in Ethiopia. This study explores the variation of carbon stock due to a forest dis...

Tropical forests have the largest potential to mitigate climate change amongst the world’s forests through conservation of existing carbon pools and expansion of carbon sinks . Ethiopia is one of tropical country which has significant forest resource but the studies on carbon stock variation along environmental variables have not been well studied....

This paper reviews various articles and documents on relationship between climate change and agriculture. The two-way relationship of climate change and agriculture is of great significance in particular to developing countries due to their large dependence on agricultural practice for livelihoods and their lack of infrastructure for adaptation whe...
