Modeling the response of tropical highland herbaceous grassland species to climate change: The case of the Arsi mountains of Ethiopia Mekasha, A.; Nigatu, L.; Tesfaye, K.; Duncan, A.J. Global warming is forcing plant and animal species to respond either through pole-ward or upslope migration to adjust to temperature increases, and grassland communities are not an exception to this phenomenon. In this study, we modeled the response of herbaceous species of grasslands within the Arsi Mountains in Ethiopia under no-migration and with migration scenarios to the projected 4.2 °C increase of temperature by 2090 (under the A2 emission scenario). For 67 species of grasses and legumes, we determined the current and predicted altitudinal limits and calculated current and projected area coverage using a Digital Elevation Model. The results indicated that the projected warming significantly reduced altitudinal ranges and habitat areas of all the species studied. All the studied species faced range contraction and habitat loss with range shift gaps among forty two species under the no-migration scenario. With the migration scenario, however, the forty two species with range shift gaps are predicted to benefit from at least some habitat area retention. Between growth forms, legumes are predicted to lose significantly more habitat area than grasses under the no-migration scenario while no significant difference in habitat area loss is predicted under the migration scenario. It can be concluded that management options are required to facilitate upslope species migration to survive under the warming climate. This could involve leaving suitable dispersal corridors and assisted colonization depending on species behavior and level of extinction risk predicted under the projected warming.

Aflatoxins: Finding solutions for improved food safety Unnevehr, L.; Grace, D. A key tenet of the CGIAR Research Program on Agriculture for Nutrition and Health (A4NH) is that agricultural practices, interventions, and policies can be better configured both to maximize health and nutrition benefits and to reduce health risks. This is particularly true regarding aflatoxins and other mycotoxins, an important food safety health risk with significant implications for developing countries. Aflatoxin exposure is particularly problematic in low-income populations in the tropics that consume relatively large quantities of staples, particularly maize and groundnuts. The best documented health impact of chronic exposure to aflatoxins is liver cancer. It is estimated that 26,000 Africans living south of the Sahara die annually of liver cancer associated with aflatoxin exposure. Broader health effects such as immune suppression with higher rates of illness and child stunting have also been associated with aflatoxin exposure. The presence of aflatoxins can also limit the growth of commercial markets and trade. As but one example, aflatoxin contamination has sharply limited the quantities of maize that the World Food Programme has been able to purchase locally in Africa since 2007. Given the complexity of the problem of controlling aflatoxins, IFPRI’s 2020 Vision Initiative and A4NH invited Laurian Unnevehr and Delia Grace to convene a diverse panel of global aflatoxin experts to write briefs surveying the emerging policy-relevant research. We would like to express our appreciation to the editors, Laurian Unnevehr and Delia Grace, the authors of the briefs, and the anonymous peer reviewers for their contributions to this effort. This set of 2020 Vision briefs provides key insights into aflatoxin control and how we can bring about a shift from a market characterized by poor information, low food quality, and high public health risk to one in which improvements in both information and technology facilitate better market opportunities and income, higher quality food, and reduced health risk.
Improving livelihoods through goat rearing and commercialisation in Mozambique ILRI Through photographs and captions, this film shares experiences from a 'Small ruminant value chains as platforms for reducing poverty and increasing food security in dryland areas of India and Mozambique' (imGoats) project. Between 2011 and 2013, the imGoats project worked with farmers in Inhassoro District in Mozambique to transform their goat farming and marketing into a commercially-viable activity.
