Several recent advances in turbulent dynamo theory are reviewed. High resolution simulations of small-scale and large-scale dynamo action in periodic domains are compared with each other and contrasted with similar results at low magnetic Prandtl numbers. It is argued that all the different cases show similarities at intermediate length scales. On the other hand, in the presence of helicity of ...

The unsaturated zone (UZ) extends across the Earth’s terrestrial surface and is central to many problems related land water resource management. Flow of through UZ typically thought be slow diffusive, such that it could attenuate fluxes dampen variability between atmospheric inputs underlying aquifer systems. This would reduce vulnerability contaminants water-related hazards. Reducing or negati...

Small-scale irrigation has gained momentum in recent years as one of the development priorities Sub-Saharan Africa. However, farmer-led is often informal with little support from extension services and a paucity data on land suitability for irrigation. To map spatial explicit dry season small-scale irrigation, we developed method using an ensemble boosted regression trees, random forest, maximu...

This paper analyses whether agricultural information flows give rise to social learning effects in banana cultivation in Nyakatoke, a small Tanzanian village. Based on a village census, full information is available on socio-economic characteristics and banana production of farmer kinship members, neighbours and informal insurance group members. This allows a test for social learning within the...

Hunger and malnutrition can be significantly reduced in developing nations by improving the farmer-to-consumer system. One important step in particular that can be improved is cold storage at the local level. If small, rural farmers could have access to affordable and reliable chilled storage, more produce would reach the consumer, and the farmer would see his income increase. A team of several...

This study examines the impact of contract farming with Farmer Organizations on farmers’ income. Contract farming with farmer organizations is a smallholder farmer-inclusive contract farming system. Field surveys were conducted in August 2010 with 75 farmers (including 39 contract farmers) in Kampong Thom province, Cambodia. The analysis—i.e., using a treatment effects model—indicates that cont...

The objective of the project is to examine recent progress in two major areas of research – computer science and neuroscience, and their related fields – and to understand whether progress in understanding cognition in living systems has new insights to offer those researching the construction of artificial cognitive systems. * Authors listed in alphabetical order. Authorship of specific sectio...
