Article
Full-text available
The paper provides a systematic review of satellite-based regional and urban heat island (RHI and UHI) studies in cities and their challenges, from 2010 to the present based on visualizing scientific landscapes (VOS) viewer analysis and Scopus and science database search using a set of standard criteria. The review results show that 52.17% of the s...
Article
Understanding the dependence of ecosystem services (ESs) on the dynamics of human-semi nature-coupled ecosystems is crucial for urban ecosystem resilience. In the present study, the responses of ESs to land use land cover transitions were explored and compared, selecting Addis Ababa, Adama, Hawassa, and Bahir Dar cities in Ethiopia. The geospatial...
Article
Green space (GS) is a central element of urban ecosystems while, urbanization is substantially changed green land into impervious ecosystems, which has then troubled the equilibrium of the surface thermal energy and the ecosystem services fluxes. This study was intended to explore the response of relative land surface temperature (RLST) intensities...

This study was conducted to assess the role of homegardens for in situ conservation of plant biodiversity in Holeta Town. In the garden data collection 75 homegardens were randomly selected. Ethnobotanical data were collected using homegarden observation, semi-structured interviews and market survey. Data were analyzed using preference ranking, dir...
Article

Healthy ecosystems benefit humans in various forms, and ecosystem services (ESs) are the benefits reaped by people in various forms. However, increase in global human population and the resulting anthropogenic activities have led to rapid alterations in the composition, structure, and functions of the ecosystems as well as their degradation, increa...
Article
Full-text available
Fast-growing, stress-tolerant tree species belonging to the genus Eucalyptus have historically been introduced in the central highlands of Ethiopia to support various economic and environment-regulating functions. While these non-native tree species are often highly useful, many are simultaneously invasive, generating negative environmental impacts...
Article
Full-text available
In this study, the dynamics of green spaces and land surface temperature patterns in four cities in Ethiopia were investigated using Landsat imagery. The typical characteristics of LST over the past three decades (1990–2020) in relation to green space dynamics were first investigated; subsequently, the spatial distribution of LST was characterized...

Urban forests contribute to climate regulation by controlling GHG emissions. The objective of this study was to estimate the total carbon stock's potential of the Yeka Park Kotebe Metropolitan University and their role in climate change mitigation and enhancement of ecosystem services. There were 4064 trees recorded in the selected study sites in w...
Article
Full-text available
Background Understanding the dependence of ecological land and dynamics of the human-nature-coupled landscape is crucial for urban ecosystem resilience. In this study, we characterized and compared the Spatio-temporal responses of ecological land to urban landscape dynamics in Bahir Dar, Addis Ababa, Adama, and Hawassa cities in Ethiopia for the la...

Background: Understanding the dependence of ecological land to dynamics of human-nature-coupled landscape is crucial for urban ecosystem resilience. The aim of present study is, explored and compared the spaciotemporal responses of ecological land to urban landscape dynamics in Bahir Dar, Addis Ababa, Adama and Hawassa cities for the last three dec...

Full-text available
The aim of this study was to examine the effect of human urine on soil quality and salinity through repeated applications, and compare it with the effects of synthetic fertilizer and non-fertilized treatments. Six different fertilizer mixtures were applied to pots of head cabbage: 100% tap water, 100% urine, 1:1 urine and tap water, 1:2 urine and t...

Higher educational institutions use large amount of paper for students’ assessment each year. As recycling is one of the best options for efficient material utilization and waste management, the potential in higher education institutions was assessed taking Kotebe Metropolitan University (KMU) and Ethiopian Civil Service University (ECSU) as sampli...

Bioprospecting involves the search of biodiversity for valuable genetic or biochemical resources/information or both for purely scientific or commercial purposes. Objective:The aim of the study was to identify potential genetic resources for bioprospecting and assess opportunities for future bioprospecting in Ethiopia. Methods: Ethno-biological dat...

i have a plan to conduct surface urban heat island / land surface temperature study. Which of the Thermal bands to use when calculating temperature from a sentinel imagery?which one is more advanced from Landsat and sentinel?
Question
How I will conducted urban ecosystem services mapping and valuation research by modeling? Which type of modeling is appropriate for such kind study? Who is the most potential respecter / supervisor in this area? Would you please inform?
Question
The third pillar principle of CBD is access benefit and equitable sharing of genetic resource after bioprospecting. For this process threshold level study is important. So how can we study it?
