This review was made to bring forth the contradicting outlooks from different research findings, challenges on the Eucalyptus species and show the opportunities we have with the tree. Due to the impact of Eucalyptus tree species on ecological health and agricultural productivity, ecologists, policy makers and politicians have had a negative view on this tree species. Hence, attempts are made to remove the tree from the agricultural landscape in some part of Ethiopia. In contrast, the farmers of Ethiopia prefer the fast growing, economically attractive, and the quality wood yields of Eucalyptus tree species. So we need to look for other dimension to coincide the existing contradictions. Eradication of the tree cannot be solution without replacing with suitable tree species for maintaining biodiversity and ecological balance. The tree can continue to supply fuel wood and construction material and thereby retard the rate of deforestation and loss of biodiversity resources of the remnant forests of the country. Collaborative work is crucial to gear efforts towards the establishment of a proper management system for the cultivation of Eucalyptus tree. Appropriate management practices such as species selection, planting site selection, correct site-species matching and efficient utilization can maximize the opportunity obtained from the tree. It is also very important to look for alternative trees species to replace Eucalyptus trees, and further studies are required to test the level of Eucalyptus species impact on specific ecosystem. Also, polices need to achieve a reasonable trade-off between the socioeconomic value and agro-ecological conservation.

This study assessed current and historic land use, land cover (LULC) dynamics and the level of urbanization in Wolaita Sodo and its peripheries since 1985 up to 2016. Thus, it's aimed to offer an increased understanding of the growing dynamics of land use changes in relation to the level of urbanization. The study primarily employed advanced technologies like GIS and RS to collect and analyze accurate and reliable information. In addition, survey questionnaire was used to gather quantitative and qualitative data from 200 respondents and then linear regression model and descriptive analysis was done by using SPSS v.21 software. The study showed that the area under forestland, bare land, grassland and cropland were declined while the area under built-up area was increased. The spatial coverage of built-up area (Wolaita Sodo) increased from 8.9% in 1985 to 32% in 2016 and increased by 216.8% (8.4ha yr -1 ) between 1985 and 2016. In addition, linear regression analysis also showed that changes in land use were strongly correlated with population growth, except rural settlement. Particularly, the strong positive relationship between urbanization and population growth suggested that demographic and economic factors are the primary drivers of urbanization. The findings of this study possibly indicated that appropriate planning policy should be devised to manage the expansion of the urbanized area so that land is used efficiently as population grows and ensure that urban development also benefits local communities.

This review paper is intended to exhibit the interplays between environmental change and rapid population growth in developing countries. In the course of discussion, the impacts of rapidly population growing on the environment have been discussed, and evidence, from various parts of the world have been traced. Studies on the impacts of population pressure on environment have been critically reviewed. It is revealed that all across the developing countries, farm size is shrinking as farmers continue to subdivide holdings among their children. In countries such as Malawi, Rwanda, Ethiopia, Haiti, Nepal and Bangladesh, population growth rates are high, and the non-farm sector is still in its early stages of development. Demographic pressure, land scarcity, and land fragmentation drive greater rural vulnerability and poverty, marked by decreased food security, inadequate response to such natural disasters such as drought or pest infestations, weakened resilience to shocks, and poor health. It is not just the supply of food, fodder, and fuel wood but the resource base itself and the lives that depend upon it are being affected. The evidences pinpoints that man through his non-sustainable production and consumption patterns, is placed at the heart of environmental changes. However, contradictory view, and practices are also in place that the population growth has positive impacts environmental restoration and improvements, while other evidences show insignificant effect of population on the environment. This contradicting scenario puts scholars in argument, and still need further research. Hence, it would be a blind generalization to draw conclusion from this relationship alone, rather, another factor that acts beyond population pressure must also be considered to justify the impact of population on environmental changes.
