Ecotourism is expressed as when tourists are attracted to a given geographic area (i.e. space) which has its own available natural, environmental, and socioeconomic resources by considering environmental sustainability, local benefit, and promotion. Space is an elementary part of ecotourism activities. Hence, the aim of this study is to identify po...

Climate change and variability is one of the common challenges of rainfall dependent economic activities like agriculture. In this study, we assessed the perception of small landholders on the impact of climate change and their adaptation strategies in Mareko district in southern Ethiopia. Data were collected from a total of 120 small farmers from...

Abstract Background: Ensete plant (Enset ventricosum) is a monocarpic perennial crop, found under genus Ensete. It is mainly known and planted by farmers as a drought resistant crop and staple food in the rural community of southern Ethiopia. Large numbers of enset clones are growing in a wide range of altitude. Currently, enset plant diversity and...
