BACKGROUND Identifying risk factors for zoonotic influenza transmission may aid public health officials in pandemic influenza planning. OBJECTIVES We sought to evaluate rural Iowan agriculture workers exposed to poultry for previous evidence of avian influenza virus infection. METHODS In 2004 we enrolled 803 rural adult Iowans in a 2-year prospective study of zoonotic influenza transmission...

Duck populations are considered to be a reservoir of Highly pathogenic avian influenza (HPAI) virus H5N1 in some agricultural production systems, as they are able to shed the virus for several days without clinical signs. Countries endemically affected with HPAI in Asia are characterised by production systems where ducks are fed on post-harvest spilled rice. During this scavenging process it is...

The field-scale application of apparent soil electrical conductivity (ECa) to agriculture has its origin in the measurement of soil salinity, which is an arid-zone problem associated with irrigated agricultural land and with areas having shallow water tables. Apparent soil electrical conductivity is influenced by a combination of physico-chemical properties including soluble salts, clay content...

While there is considerable interest in understanding the climate-migration relationship, particularly in the context of concerns about global climatic change, little is known about underlying mechanisms. We analyze a unique and extensive set of panel data characterizing annual bilateral international migration flows from 163 origin countries to 42 OECD destination countries covering the last t...

BACKGROUND The use of highly hazardous pesticides by smallholder farmers constitutes a classic trans-sectoral 'wicked problem'. We share our program of research in potato and vegetable farming communities in the Andean highlands, working with partners from multiple sectors to confront this problem over several projects. METHODS We engaged in iterative cycles of mixed methods research around p...
