“…However, few of them understand its relevance in promoting health and preventing chronic noncommunicable diseases. This is consistent with the study conducted in Bahir Dar and Hawassa cities where most of the study participants were aware of the aesthetic value of green spaces [15,39]. This requires that effort be directed to increasing the awareness and understanding of community members regarding added health benefits of green spaces.…”

“…They may provide a sense of tranquility and encourage the use of outdoor spaces. Gardening in green spaces may also help promote mental and psychological health and reduce stress [14][15][16][17][18][19]. In addition, recreational services provided at green spaces and parks may generate revenues and create employment opportunities for low-income neighborhoods, which may in turn reduce crime and aggressive anti-social behaviors [20][21][22].…”

Physical structure and activities undertaken at green spaces provide substantial health, social, environmental, psychological, and economic benefits to residents of an urban area. Study regarding the health benefits of green spaces in developing countries is very limited. Addis Ababa is the capital and the largest city in Ethiopia and not many studies on green spaces are available. Thus, this community-based cross-sectional study was conducted among 204 residents of Addis Ababa city. A multistage sampling technique was used, the sample size was allocated proportionally and selected by a simple random sampling technique. Data were coded and entered into Epi Info ™ 7 and exported to SPSS version 25 for cleaning and analysis. Results showed that only 30% of the respondents visited green spaces in the last 12 months. The common reasons for the visit were to adore nature (30.4%), refresh mind (25%), and "breathe quality air" (20.6%). Although most study participants were aware of the appealing psychological benefits of green spaces, only 55.9% of them had a positive perception regarding the health benefits of green spaces. Compared with the negative perception those with positive perception were more than twice more likely to visit green spaces (AOR: 2.51; 95% CI: 1.33-4.77). The study concluded that in addition to expanding the green spaces efforts have to be directed to solving challenges that discourage visits, increasing awareness, and improving the perception of the community regarding added health benefits of green spaces.

“…These results differed from those obtained in other works on appraisal of urban trees [22,23] or landscape appraisal [8,24], where some differences were detected due to sex and education level. However, they were consistent with other results for green infrastructure [25] and Mediterranean landscape [26].…”

Analysis of Differences in the Choice of the Economic Value of Urban Trees in Madrid When Displayed in Situ and in Photographs

et al. 2020

The determination of an asset’s economic value has always been an important step in improving its management. The Madrid Region legislated the application of the first version of the Norma Granada as a method of appraising ornamental trees. However, the trees in the city of Madrid are only assessed in terms of ecosystem services (i-Tree Eco). A photograph of the asset to be appraised is often used in studies on the valuation of publicly-owned socio-environmental assets such as trees or landscapes. As a tree’s value is very closely linked to its size and to a number of features that can be seen through direct observation of the specimen, it is important to verify the validity of photographs as a method for obtaining the public’s opinion. This work presents a comparison between the valuations chosen by members of the public when observing the tree in situ and in a photograph. The aim is to verify the validity of photographs for their application to a larger sample and to understand qualitatively how citizens assess the trees in a city. The following appraisal methods were used: the American method, Council of Tree Landscape Appraisers (CTLA), Norma Granada and the Burnley method. The survey consisted of ten specimens from ten different species, and ten surveys were taken for each stem, making a total of 100 for each tree species and 1000 surveys in all. The surveys were done randomly and individually. Each interviewed chose one of the three values they were shown when observing the specimen in the photograph and in situ; 84% of the 1000 surveys gave as a result the same value choice when looking at the specimen on site and seeing it in a photograph.

“…Among the signifcant contributions, environmental, economic, and social benefts to urban dwellers have been reported by diferent authors. In Ethiopia, studies on the environment's role in enhancing values to city health in Addis Ababa by [27]; cooling efect at Hawassa, Sodo, and Bodity by [26]; and at Hawassa and Bahir Dar by [29]. Similarly, the biodiversity conservation role of PRGIs has been reported for Arbamich [4], Sebeta [5], Hawassa [11], Mekelle [10] and Jimma [14].…”

Urban forests have an important role in biodiversity conservation, environmental improvement, and ecosystem services including climate change mitigation enhancement. The objectives of the current study were to: assess plant types and management strategies of the owners; woody species’ composition, structure, and diversity; and estimate aboveground biomass of trees and associated carbon stock in private residential green infrastructure (PRGI) at Dilla town. This study was conducted at three kebeles, the lowest administrative unit in Ethiopia. Ninety-four households were randomly selected from a proportional sample size for each kebele. A complete inventory of woody species was done after measuring the area occupied by plants at each household. At plot level, the aboveground biomass of sampled trees was calculated by using an allometric biomass equation developed for agroforestry species. Diversity was described by using different indices The free software EstimateS 9.1.0 was used to generate data for the construction of sample-based rarefaction curves and SPSS version 20 for descriptive statistics. Based on plant types and arrangement, the households manage their PRGI in 15 categories on area size, ranging from 10 m2 to 1229 m2, with an average holding size of 207.5 m2. A total of 66 plant species belonging to 45 families were identified. Overall, a total of 1220 stem ha−1 contributed to an aboveground carbon stock of 64.35 ton ha−1 of which 50.4% is from fruit trees and the rest from timber trees. The results suggest that PRGIs can serve as reservoirs of non-native and native plant species, including five native tree species currently facing conservation concerns.
