This study aims to critically understand the involvement of external actors, most notably Kenya and Ethiopia in the Somali conflict. It also aims to discuss peace prospect for Somalia in consideration with regional interest. Adopting Mary Kaldor’s “New War” theory that explains the changing context and transnational character of wars in the new era, and Michael E. Brown’s concept of causes and Regional Dimensions of Internal Conflict in combination with applied peace and conflict research method, the study finds that the involvement of neighbouring states, particularly Kenya and Ethiopia, in the Somali conflict is necessitated by the “spill-over” effect of the internal conflict coupled with transnational threats posed to their national security by various local and international actors. Furthermore, the study reveals that Somalia’s conflict hosts a variety of politically, religiously and militarily motivated external actors, who also openly vowed to internationalize their activities. As a result, the connections between local actors in Somalia and terrorist groups operating elsewhere, but cooperating with them, have become a source of continuous instability to Somalia, the eastern African region and beyond. This situation makes an international action imperative as the prospect for peace in Somalia is still in place. Thus, in order to to end wars and create a durable peace in Somalia, this study suggests Michael E. Brown’s ‘co-optation’ and ‘neutralization’ strategies along with an extensive international efforts including humanitarian assistance and local institutions building, which may help to restore peace, rule of law and ensure long term stability in Somalia.

The oil from the Exxon Valdez incident is still observed in different Prince William Sound beaches over two decades. The persisting oil is slightly weathered and highly toxic to the environment. Several studies investigated the reasons for lingering oil. Different remediation techniques were tried and the results were not satisfactory. Recently, it was found that the oil is stranded in a low permeability layer. Detailed explorations showed that the exchange of the nutrients and oxygen is limited in this layer. The main objective of the present study is to explain the effect of oxygen and nutrients on the degradation phenomena in the Alaskan beaches. The general approach for this study is a combination of the field experiments and lab analysis. As it is important to eliminate any cross-layer contamination, a unique sampling method was developed. The applied method involves collecting samples from the oily layer (low permeability layer), measuring oxygen levels in the field and comparing them with the nutrient samples analyzed in the lab. The findings showed that the nutrients levels were low in the beach but the lack of effective electron acceptor is the major factor limiting the biodegradation of the oil. The seawater is responsible for delivering the oxygen and nutrients to the beach during the high tide while during low tide the landward freshwater discharges to the beach. The study of the sulfate and nitrate in the beach revealed that the levels of the alternative electron acceptors were not sufficient to support anaerobic biodegradation. Finally, for successful biodegradation of the Exxon Valdez oil, adequate levels of nutrients (nitrogen and phosphorous) and along with oxygen are required. / Civil Engineering
