Climate, vegetation and fire history during the past 18,000 years, recorded in high altitude lacustrine sediments on the Sanetti Plateau, Bale Mountains (Ethiopia) by Mekonnen, Betelhem, Glaser, Bruno, Zech, Roland, Zech, Michael, Schlütz, Frank, Bussert, Robert, Gil-Romera, Graciela, Nemomissa, Sileshi, Bekele, Tamrat, Bittner, Lucas, Solomon, Dawit, Manhart, Andreas

“…However, records often suffer from poor age control, resolution, and/or ambiguous proxy interpretation, and only little focus has been put on high-altitude regions despite their sensitivity to global, regional, and local climate change phenomena. Here we report on Last Glacial environmental fluctuations at about 4000 m asl on the Sanetti Plateau in the Bale Mountains (SE Ethiopia), based on biogeochemical and palynological analyses of laminated lacustrine sediments. …”

Research progress on greenhouse gas emissions from livestock in sub-Saharan Africa falls short of national inventory ambitions by Graham, Michael, Butterbach-Bahl, Klaus, Toit, C.J.L. du, Korir, Daniel, Leitner, Sonja, Merbold, Lutz, Mwape, A., Ndung'u, Phyllis W., Pelster, David E., Rufino, Mariana C., Weerden, Tony John van der, Wilkes, A., Arndt, Claudia

“…We found that there has been limited research on livestock GHG emissions and SOC relative to national ambitions for climate change mitigation in SSA. Enteric methane emission factors (EFs) in low productivity cattle systems may be lower than IPCC Tier 1 default EFs, whereas small ruminants (i.e. sheep and goats) had higher EFs compared to IPCC Tier 1 EFs. …”

Weight gain and enteric methane production of cattle fed on tropical grasses by Korir, Daniel, Marquardt, Svenja, Eckard, Richard, Sánchez, Andrea C., Dickhoefer, Uta, Merbold, Lutz, Butterbach-Bahl, Klaus, Jones, Christopher S., Robertson-Dean, M., Goopy, John P.

“…Conclusion: Even though animal performance and MY among treatments did not differ, the animals had higher MY and Ym than currently estimated by the Intergovernmental Panel on Climate Change. Implication: The three grasses supported similar animal growth rate, implying that growing of higher-yielding grasses such as Napier offers an opportunity to optimise land productivity in the tropics. …”
