We conducted a multi-isotope study of five fifth-century AD cemeteries in modern-day Hungary to determine relationships between nomadic-pastoralist incomers-the historically documented Huns and other nomadic groups-and the sedentary agricultural population of the late Roman province of Pannonia. Contemporary historical sources describe this relationship as adversarial and destructive for the la...
Improvements in the ability to model El Niño and other large-scale interannual climate variations have allowed for the development of seasonal climate forecasts, predicting rainfall and temperature anomalies for many places around the world. These forecasts have allowed developing countries to predict shortfalls in grain yields, with benefits for food security. Several countries communicate the...
Arylamine N-acetyltransferase 2 (NAT2) is involved in human physiological responses to a variety of xenobiotic compounds, including common therapeutic drugs and exogenous chemicals present in the diet and the environment. Many questions remain about the evolutionary mechanisms that have led to the high prevalence of slow acetylators in the human species. Evidence from recent surveys of NAT2 gen...
Our paper aims to explore the role of subsistence farming in Hungary by reviewing literature, analyzing primary data from a representative survey conducted 2018 and presenting two case-studies. According European national-level policy analysis, is cornerstone agriculture, as it central element positive rural image. The based on earlier theories farming, argues that worth different factors influ...
The greatest challenge for agriculture is to reduce the trade-offs between productivity and long-term sustainability. Therefore, it is interesting to analyse organic agriculture which is a given set of farm practices that emphasise ecological sustainability. Organic agriculture can be characterised as being less driven by off-farm inputs and being better embedded in ecosystem functions. The lit...
Forest cover transitions in the developing tropics are conditioned by agricultural change. The expansion, intensification, and diversification of agricultural land uses are tied to regional economic/environmental regimes and decisions of local farming households. Land changescienceandagrariansystems research sharean interest in the drivers of household strategies, land use impacts, and typologi...
This new project studies the diversity of socioecological niches across agropastoral transition in Andes, utilising a multi-isotope approach to track human territories and allocate subsistence tasks. During period, we discriminate different diachronic with varying extents maize farming altitudinal mobility.
Smallholder teak (Tectona grandis) plantations have been identified as a potentially valuable component of upland farming systems in northern Laos that can contribute to a “livelihood transition” from subsistence-oriented swidden agriculture to a more commercially-oriented farming system, thereby bringing about a “forest transition” at the landscape scale. In recent years, teak smallholdings ha...
