Manure management is an ever-increasing environmental impact problem within the U.S. livestock industry due to the trends in growing scale of operation of individual animal raising facilities. Anaerobic digestion, the fermentation of organic matter into a mixture of methane and carbon dioxide called biogas, offers the livestock industry a viable solution to this problem. When anaerobic digestion is combined with by-product recovery and biogas utilization, the integrated system can potentially solve manure handling issues while creating significant energy, environmental and economic opportunities. The overall objective of this project was to conduct a laboratory proof-of-concept evaluation to determine the potential energy generation and pathogen control benefits of applying anaerobic digestion for the management of swine manure

Mitigating externalities of terrorism on tourism: global evidence from police, security officers and armed service personnel

In this paper, we investigate the role of security officers, the police and armed service personnel in dampening the effect of terrorism externalities on tourist arrivals. The temporal and geographic scopes are respectively 2010-2015 and 163 countries. Four terrorism measurements are used. They include the number of: incidents, injuries, fatalities and property damages. The main findings indicate that armed service personnel can effectively be used to modulate the damaging influence of all four terrorism externalities in order to achieve a positive net effect on tourist arrivals. Conversely, the corresponding moderating role of security officers and the police is not statistically significant. Moreover, violent demonstrations and homicides have a harmful effect on tourist arrivals while the number of incarcerations displays the opposite effect. Policy implications are discussed
