Managing the environmental impacts of war: What can be learned from conflict-vulnerable communities?

Wars have serious negative effects on the total environment. This study reviews 193 case studies worldwide in order to better understand these impacts and their potential management before, during and after war. The synthesis of the evidence shows that military actions damage landscape resources. Aerial bombings have great negative impacts by damaging environmental conservation efforts, destroying trees, disturbing soilscapes and undermining soil health. In addition, war exterminates wildlife and their ecological niches and contributes to atmospheric and water pollution. Overall, military leaders and personnel have shown little concern about these impacts. Limited postwar restoration activities are also undertaken to reduce war-driven environmental impacts. The study highlights some good practices on how to manage the total environment during the warfare. Therefore, communities must share best lessons to remain in a sustainable peace, restore the war-damaged environment, and enhance sustainable economic development.

Preliminary investigation on rodent-ectoparasite associations in the highlands of Tigray, Northern Ethiopia: implications for potential zoonoses.

We studied associations between rodents and their arthropod ectoparasites in crop fields and household compounds in the highlands of Tigray, Northern Ethiopia. Ectoparasite infestation indices, such as percent infestation, mean abundance, prevalence and host preferences, were calculated for each taxon. In total, 172 rodents from crop fields and 97 from household compounds were trapped. Rodent species and numbers trapped from the crop fields and household compounds were Mastomys awashensis (Lavrenchenko, Likhnova & Baskevich, 1998) (88 and 44), Arvicanthis dembeensis (Ruppel, 1842) (63 and 37) and Acomys sp. (21 and 16), respectively. A total of 558 insects and acarids (belonging to 11 taxa) were recovered from the rodents trapped in the crop fields, and 296 insects and acarid (belonging to 6 taxa) from the rodents trapped in the household compounds. Approximately 66% of the rodents trapped from the crop fields and 47% of those trapped from the household compounds were infested with ectoparasites. Laelaps sp. (64.9%) and Xenopsylla sp. (20.6%) comprised the highest proportion of the ectoparasites recovered in the crop fields, and the same ectoparasites, but in reverse order, comprised the highest proportions in the household compounds (Xenopsylla [50.3%] and Laelaps sp. [29%]). Our study revealed that crop fields and household compounds in the highlands share similar rodents and several ectoparasites. Furthermore, at least 1 of the rodent species and some of the ectoparasites identified in this study were reported to have posed medical and veterinary threats in other parts of Ethiopia and neighboring countries.
