| The threats posed by invasive plants span ecosystems and economies worldwide. Local knowledge of biological invasions has proven beneficial for invasive species research, but to date no work has integrated this knowledge with species distribution modeling for invasion risk assessments. In this study, we integrated pastoral knowledge with Maxent modeling to assess the suitable habitat and potential impacts of invasive Cryptostegia grandiflora Robx. Ex R.Br. (rubber vine) in Ethiopia’s Afar region. We conducted focus groups with seven villages across the Amibara and Awash-Fentale districts. Pastoral knowledge revealed the growing threat of rubber vine, which to date has received limited attention in Ethiopia, and whose presence in Afar was... |

| Farmers’ practices in the management of agricultural landscapes influence biodiversity with implications for livelihoods, ecosystem service provision, and biodiversity conservation. In this study, we examined how smallholding farmers in an agriculture-forest mosaic landscape in southwestern Ethiopia manage trees and forests with regard to a few selected ecosystem services and disservices that they highlighted as “beneficial” or “problematic.” Qualitative and quantitative data were collected from six villages, located both near and far from forest, using participatory field mapping and semistructured interviews, tree species inventory, focus group discussions, and observation. The study showed that... |

| Background: Human intestinal schistosomiasis caused by Schistosoma mansoni and urinary schistosomiasis caused by Schistosoma haematobium are endemic in Ethiopia. Although schistosomes look morphologically uniform, there is variation in infectivity, egg productivity and virulence due to variation in their genetic make. Knowing the genetic diversity and population structure of S. mansoni isolates will enable to understand and consider the possible variability in terms of infectivity, egg productivity and virulence. Methods: Between 2010 and 2011, genetic diversity and population structure of Schistosoma mansoni isolates from four endemic areas of Ethiopia was assessed using previously published 11 polymorphic microsatellite loci. Miracidia were hatched from... |

| This study argues that famines are preventable. What was once a universal threat to human life is now primarily in Sub-Saharan Africa. Africa is likely to be the only continent to experience a continued high level of famine mortality during the 1990s, as well as an increase in absolute poverty. Therefore, the current challenge facing policymakers and research organizations such as IFPRI is to reduce the negative effects of famine in Africa and to lay the foundations for its longer- term eradication. This research by Patrick Webb, Joachim von Braum, and Yisehac Yohannes was designed to contribute to a better understanding of the root causes of famine and thereby to identify appropriate policies and projects for famine mitigation. As part of a larger IFPRI... |

| On farm conservation of crop diversity poses obvious policy challenges in terms of the design of appropriate incentive mechanisms and possible trade-offs between conservation and productivity. This paper compares factors explaining the inter-specific diversity (diversity among species) and infra-specific diversity (diversity among varieties within a species) of cereal crops grown in communities and on individual farms in the northern Ethiopian highlands. Using named varieties and ecological indices of spatial diversity (richness, evenness, and inverse dominance), we find that a combination of factors related to the agro-ecology of a community, its access to markets, and the characteristics of its households and farms significantly affect both the inter-... |

| Over the past decade, coffee producers have been struggling with the world market’s low and unstable coffee prices. Some coffee producing countries try to overcome this crisis by moving from pure commodity exports to higher-price exports of niche market quality products, like “single-origin coffee”, protected by intellectual property tools. Such protection can take the form of trademarks or geographical indications. At present within the single-origin coffee sector, a trend to use the latter form can be observed. For example, “Café de Colombia” was registered as a Protected Geographical Indication under Council Regulation (EC) No 510/2006. Another recent example is the Ethiopian Fine Coffee Trademarking and Licensing Initiative. In order to protect its... |
