Der vorliegende Beitrag stellt empirische Ergebnisse zur Analyse von Marktverhalten der russischen Exporteure auf den internationalen Märkten für Düngemittel vor. Der Fokus auf Russland begründet sich darin, dass das Land beim Einsturz des Kali-Kartells stark im Rampenlicht stand. Bei zwei...

Croatian farming systems have become more intensive in recent years. There is some evidence of rising NO3-N-levels in ground water. The aim of the paper is to find possible ways of preventing NO3-levels to rise in Croatian farming systems and their implications from the viewpoint of the manager....

Ocean iron fertilization is currently discussed as a potential measure to mitigate climate change by enhancing oceanic CO2 uptake. Its mitigation potential is not yet well explored, and carbon offsets generated through iron fertilization activities could currently not be traded on regulated...

Diminishing emission budgets and increasing risks of catastrophic damages from climate change require analyses of rapid response options including geoengineering options such as ocean iron fertilization (OIF). To decide whether or not OIF might be such an option an assessment of its potential as...

Despite large uncertainties in the fertilization efficiency, natural iron fertilization studies and some of the purposeful iron enrichment studies have demonstrated that Southern Ocean iron fertilization can lead to a significant export of carbon from the sea surface to the ocean interior. From...

To stay within the 2êC temperature increase target for climate change calls for ambitious emission reduction targets already for the 2012-2020 compliance period. Cost-efficiency is a crucial criterion for the enforcement of such ambitious targets, requiring analyses of all possible abatement...

Diffuse pollution from agriculture is often responsible for observed concentrations of agricultural compounds being in excess of the upper limits prescribed by the EU Water Framework Directive (WFD) in some river catchments and reductions in these concentrations will require widespread changes...

This report presents a pan-European overview of the geographical distribution, and severity of adverse effects, of excessive anthropogenic inputs of nutrients in European ecosystems.

The objective of this paper is to analyze the relative importance of knowledge inputs (or "technical change") and input prices in explaining factor demand in Argentine agriculture. Motivation for the paper is the fifteen-fold increase in fertilizer demand observed in Argentina in the 1990-2019...
