The transition to agriculture was a key event in human history. The extent to which this transition is associated with biological changes in different world regions remains debated. Cultural and osteological records in Lower Nubia throughout the Holocene have been interpreted as a result of in situ differentiation or alternatively as migratory events and possible admixture with surrounding popu...
The huge changes in agricultural activities, which may be amplified by the forthcoming Common Agriculture Policy reform, call the future of crop-livestock systems into question and hence the impact of these changes on landscapes and biodiversity. We analyzed relationships between agriculture, landscape and biodiversity in south-western France. The study area covered about 4,000 ha and included ...
The paper analyses various forms of direct payments using the spatial and dynamic model AgriPoliS. In AgriPoliS farms are represented as agents which act and interact individually. This allows for endogenous structural change. The model is fitted to the agricultural region 'Hohenlohe' in Baden-Württemberg which is characterised by intensive livestock farming. The policy simulations show that th...
The emergence and spread of the mobile colistin resistance gene (mcr-1) has become a major global public health concern. So far, this gene has been widely detected in food animals, pets, food, and humans. However, there is little information on the contamination of mcr-1-containing bacteria in farming soils. In August 2016, a survey of ESBL-producing Escherichia coli isolated from farming soils...
Examining characteristics of traditional nomadic herding cultures and traditional sedentary farming cultures, both of which are deeply established in Central Asian history, this paper provides evidence on the persistence of gender roles in culture, spillovers from one culture to another, and the impacts of efforts promoting gender equality. First, I investigate whether differences in gender rol...
BACKGROUND Increasing livestock density and animal manure spreading, along with climate factors such as heavy rainfall, may increase the risk of acute gastrointestinal illness (AGI). In this study we evaluated the association between farming activities, precipitation and AGI. METHODS A cross-sectional telephone survey of randomly selected residents (n = 7006) of 54 rural municipalities in Que...
The growth of organic farming practices in the last few decades is continuing to stimulate the international debate about this alternative food market. As a p art of a PhD project r esearch about embeddedness in Alternative Food Networks (AFNs), this paper focuses on the promotional aspects of organic farms websites from the Madrid region. As a theoretical tool, some knowledge categories drawn ...
