To achieve this objective, the study employed fundamentally qualitative with limited quantitative methods to collect relevant data. It used both primary and secondary sources of data. The primary data was collected from 55 participants via in-depth informant interview, focus group discussants representing the grass root societies such as smallholder farmers, local residents and other key informants selected based on purposeful sampling. Secondary data was obtained through critical review and analysis of related literatures and appropriate documents. The methods were In-depth Informants Interview (III), Focus Group Discussions (FGDs), Key Informants Interview (KII) and personal observations and employed qualitative analysis with limited quantitative analysis. Based on the study, the causes of environmental degradation in Erob Wereda are several intertwined and conglomeration factors. The core finding of the study displayed that, environmental degradation has actual, unprecedented and multitudinous effect on human security which undermine food, economic, health, social and personal security of farmers and environmental dependent peoples of Erob Wereda. Each household is prevalently faced inter-household conflict, food shortage, economic deterioration and misery due to declining of their agricultural, cattle and honey production from time to time. Moreover, diminishing in land, bushes/forest and water resources has significant impact on weakening of socio-economic values; undermine means of production and livelihood and may extend as major threat to the future generation. The study also proclaimed that single environmental problem can have many threats starting from the household to the national and international level. Thus, the results indicate that extensive environmental degradation poses multiple challenges to human security. So, to solve repercussion of environmental risks, environmental issues should be critically dealt with. The study also revealed that the adverse effect of environmental degradation in Erob Wereda is exodus migration which threat personal security and social disintegration. Generally, resource degradation is serious problem and poses myriad challenge in the study area. The environment in the area has become more fragile than ever resulting decline in agricultural production and productivity, frequent food deficiency, health problems, drought and famines that severely impair human security. Finally, the study set-forth that there is interactive and vicious causality-effect correlation between environmental degradation and human security.
