| Increasing concerns about global food security, depleting fossil reserves and diminishing natural resources question the continuation of energy-intensive conventional agriculture and emphasize the importance of sustainable alternatives such as organic agriculture. Even though organic farming is more ecologically sustainable and often economically advantageous, widespread adoption is limited as farmers making adoption-decisions are faced with challenging trade-offs (e.g. lower yields in the short term, limited options for crop nutrition and pest control and non-existence of markets for organic produce). This highlights the importance of innovation platforms involving relevant stakeholders (farmers, researchers, extensionists, etc.) in decision-making... |

| Yams (Dioscorea spp.) are widely grown throughout the tropics. Three yam species constitute the staple for more than 60 million people in five West African coastal countries, where more than 90% of the world's production takes place. Here we give a general introduction to yams, including their origin and geographic distribution as well as different types of yams common in Africa and Asia, and outline their uses. However, the main body in this chapter pertains to the agricultural production practices, including information on climatic requirements, soil type and land preparation, propagation, agronomic practices, pests and diseases (and their control), harvesting, curing and storage. Finally, we elaborate on the need for future research, in particular on... |

| Plants are a major factor influencing methane emissions from wetlands, along with environmental parameters such as water table, temperature, pH, nutrients and soil carbon substrate. We conducted a field experiment to study how different plant species influence methane emissions from a wetland in Switzerland. The top 0.5 m of soil at this site had been removed five years earlier, leaving a substrate with very low methanogenic activity. We found a sixfold difference among plant species in their effect on methane emission rates: Molinia caerulea and Lysimachia vulgaris caused low emission rates, whereas Senecio paludosus, Carex flava, Juncus effusus and Typha latifolia caused relatively high rates. Centaurea jacea, Iris sibirica, and Carex davalliana caused... |
