Nowadays, addressing urban climate in urban planning through mapping has got world-wide attention. Greening urban environment is one of the best mechanisms to combat the effects of micro-climate change. Therefore, this study aims at analyzing the cooling effects of Urban Green Spaces (UGS) in mitigating micro-climate change in Adama City with special emphasis on land surface temperature variation with respective to vegetation cover for the last two decades i.e. from 2000 to 2020. Three different remotely sensed data of Landsat7 ETM+ (2000 and 2010) as well as Landsat8 OLI/TIRS (2020) were used in the study. The consistent land surface temperature data were retrieved from Landsat7 ETM+ and Landsat8 OLI/TIRS using mono window and split window algorithms, respectively. Regression and correlation analysis among Land Surface Temperature (LST), Normalized Difference Vegetation Index (NDVI) and Normalized Difference Built-up Index (NDBI) were also performed in Statistical Package for Social Science (SPSS V23). The study reveals that the proportion of Urban Green Spaces (UGS) to other land use/land cover particularly, dense vegetation cover were reduced from 29.3Km2(21.20%) in 2000 to 18.17Km2 (13.15%) in 2020. The main land dynamic process, which could considerably contribute to the increase in Land Surface Temperature, was the rapid expansion of built-up areas in the study area. The model produced through multiple linear regression analysis clearly indicates that the two urban parameters (built up and green areas) contributed 75.2% of the Land Surface Temperature (LST) variations in Adama City. The cooling efficiency (CE) and the threshold value of efficiency (TVoE) of green space in Adama City were calculated as 5.5 ± 0.5 ha. This finding implies that when Adama City municipality implements urban planning, allocating a green space area of 5.5 ± 0.5 ha reduces surface temperature by about 2.85 0C which is the most efficient to reduce heat effects. The study suggests that strengthening of plan execution capacity, public participation in urban planning and strengthening the development of urban green spaces as an important strategy to mitigate the effects of micro-climate change.

Resettlement program is a measure taken to reduce the problems of food insecurity and household income diversification. However, improper implementations of the program have negative impact on socio-economic and environmental related issues particularly natural resource degradation which causes LU/LC change in the study area. In the context Ethiopian, resettlement has been carried out both voluntary and involuntary nature. Voluntary resettlement program occurred with the individual interest without any external influences, whereas involuntary is related with massively implemented through government policy. This study was carried out to analyze impact of resettlement program on livelihood of indigenous community in Esira district, Dawuro zone. The livelihood strategies of indigenous community before and after resettlement program where assessed using questionnaire, key informant interviews and filed observations. The finding of this study shows that, after resettlement program the indigenous community faces the problems of access to communal resource utilizations such as common grazing area and Forest, limitation of cattle number, limited annual source of income and shifting of economic activates. On other, the resettlement program brought positive impacts for indigenous community by introducing some of fruits like avocado, mango, banana and ginger which is not familiar before the resettlement program in the study area. Based on finding, it is recommended that well planned resettlement program by considering the existed indigenous community and the newly settler through mutual benefit natural resource.
