Land use change effects on trace gas fluxes in the forest margins of Central Sulawesi, Indonesia por Veldkamp, E., Purbopuspito, J., Corre, M.D., Brumme, R., Murdiyarso, Daniel

“…Studies on the effects of land use changes and land use intensification on soil trace gas emissions were mostly conducted in Latin America and only very few in Asia. Here we present results from Central Sulawesi where profound changes in land use and cultivation practices take place: traditional agricultural practices like shifting cultivation and slash‐and‐burn agriculture are replaced by permanent cultivation systems and introduction of income‐generating cash crops like cacao. …”

Mitogenomic meta-analysis identifies two phases of migration in the history of Eastern Eurasian sheep por Feng-Hua Lv, Wei-Feng Peng, Ji Yang, Yong-Xin Zhao, Wen-Rong Li, Ming-Jun Liu, Yue-Hui Ma, Qian-Jun Zhao, Guang-Li Yang, Feng Wang, Jin-Quan Li, Yong-Gang Liu, Zhi-Qiang Shen, Sheng-Guo Zhao, Eer Hehua, Gorkhali, N.A., Farhad Vahidi, S.M., Muladno, M., Naqvi, A.N., Tabell, J., Iso-Touru, T., Bruford, M.W., Kantanen, J., Han Jianlin, Meng-Hua Li

“…A continent-scale examination of lineage diversity and approximate Bayesian computation analyses indicated that the Mongolian Plateau region was a secondary center of dispersal, acting as a “transportation hub” in eastern Eurasia: Sheep from the Middle Eastern domestication center were inferred to have migrated through the Caucasus and Central Asia, and arrived in North and Southwest China (lineages A, B, and C) and the Indian subcontinent (lineages B and C) through this region. …”

Hotspots of gross emissions from the land use sector: patterns, uncertainties, and leading emission sources for the period 2000–2005 in the tropics por Román Cuesta, Rosa María, Rufino, Mariana C., Herold, Martin, Butterbach-Bahl, Klaus, Rosenstock, Todd S., Herrero, Mario, Ogle, Stephen Michael, Li C, Poulter, B., Verchot, Louis V., Martius, Christopher, Stuiver J, Bruin, S. de

“…Our data highlight the following: (i) the existence of AFOLU emissions hotspots on all continents, with particular impor- tance of evergreen rainforest deforestation in Central and South America, fire in dry forests in Africa, and both peat- land emissions and agriculture in Asia; (ii) a predominant contribution of forests and CO2 to the total AFOLU emis- sions (69 %) and to their uncertainties (98 %); (iii) higher gross fluxes from forests, which coincide with higher uncer- tainties, making agricultural hotspots appealing for effective mitigation action; and (iv) a lower contribution of non-CO2 agricultural emissions to the total gross emissions (ca. 25 %), with livestock (15.5 %) and rice (7 %) leading the emissions. …”

Tropical maize (Zea mays L.) por Edmeades, G.O., Trevisan, W., Boddupalli, P.M., Campos, Hugo

“…The International Maize and Wheat Improvement Center (CIMMYT) has been the focus of much of this research for the past 50 years, and they, along with multinational seed companies, have been largely responsible for the major movements of elite tropical maize germplasm to Africa and Asia. Crop improvement has focused primarily on changing biomass partitioning by reducing plant height, increasing ear growth, reducing barrenness, and consistently focusing on increasing biotic and abiotic stress tolerances. …”

Sorghum grain mold: the scope of institutional innovations to support sorghum based rural livelihoods por Hall, A., Bandyopadhyay, Ranajit, Chandrashekar, A., Shewry, P., Bandyopadhyay, A.J., Chandrashekar, R.

“…The International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), Patancheru, India has estimated US$ 130 million as total losses due to grain mold in the semi-arid tropical areas of Asia and Africa (ICRISAT 1992). The poverty implications of grain mold are associated with loss of access to food, exposure to health risks through contaminated food, and income losses through lower prices. …”
