Integrated Assessment of Agricultural Systems at Multiple Scales

Agricultural policies are increasingly replaced by agro-environmental and rural-development polices. The rationale behind this evolution is that the policies seek to enhance the sustainability of agricultural systems and contributions from these systems to sustainable development at large. The same can be argued for agricultural innovations; they are increasingly aimed at serving a range of sus...

Seasonality in birth defects, agricultural production and urban location.

This paper tests whether the strength of the "spring spike" in birth defects is related to agricultural production and urban location using Texas Birth Defects Registry data for the period 1996-2007. We find evidence of a spike in birth defects among children conceived in the spring and summer, but it is more pronounced in urban non-agricultural counties than in other types of counties.

The nitrogen cascade from agricultural soils to the sea: modelling nitrogen transfers at regional watershed and global scales.

The nitrogen cycle of pre-industrial ecosystems has long been remarkably closed, in spite of the high mobility of this element in the atmosphere and hydrosphere. Inter-regional and international commercial exchanges of agricultural goods, which considerably increased after the generalization of the use of synthetic nitrogen fertilizers, introduced an additional type of nitrogen mobility, which ...
