Structural change in the dairy sector : exit from farming and farm type change

Zorn, Alexander; Zimmert, Franziska - In: Agricultural and Food Economics : AFE 10 (2022), pp. 1-31

This paper analyses the factors driving structural change in Swiss dairy farming. We focus on the most important farm type in Switzerland, dairy farms, to examine which factors contribute to a farmer's decision to abandon farming or change to suckler cow farm type. Swiss dairy farming is...

Change in N and P Concentrations in Antarctic Streams as a Response to Change in Penguin Populations

Arkadiusz, Nędzarek - In: Papers on Global Change IGBP 17 (2010) 1, pp. 67-80

This study presents changes in the concentrations of nitrogen and phosphorus in two streams in Western Antarctica … concentrations of the determined forms of N and P between 2001 and 2005. The decrease ranged from 9.3% for reactive phosphorus to 73 ….2% for ammonium-nitrogen. Such inferred declines in N and P concentrations are considered to reflect reduced deposition on …
