Regulating Ocean Fertilization under International Law: The Risks
© Lexxion Verlagsgesellschaft mbH (6/2013)
This paper explores the regulatory regime for ocean fertilization under the Dumping regime, which comprises the 1972 London Convention and 1996 Protocol. It assesses the extent to which ocean fertilization is presently subject to mandatory and voluntary controls and provides an overview of the proposals currently under active consideration designed to develop a comprehensive regime for ocean fertilization. Whilst acknowledging the benefits of regulation and the importance of environmental protection, this paper concludes with a warning against considering ocean fertilization in isolation from the broader context of geoengineering and climate change more generally.

Application of computer modelling for forecasting of contaminants distribution in soil
© Aristotle University of Thessaloniki (6/2009)
An outlook of various methods of computer modeling application for the analysis and forecasting of contaminants migration in the soil is being discussed. A new mathematical model of contaminants transport in near-surface soil layer under non-isothermal conditions is being proposed. The given model takes into account the soil moisture content change effecting the solute transport and sorption owing to evaporation processes and recondensation of water vapor. The article also covers the possibility of hybrid expert systems (HES) application for solving contaminants migration in the soil. Distinguish structure of HES that includes models hybridization is being proposed. On the basis of given methods and models a new software has been developed.

The FOOTPRINT software tools: Pesticide risk assessment and management in the EU at different spatial scales
© Aristotle University of Thessaloniki (6/2009)
In the EU-project FOOTPRINT three pesticide risk assessment and management tools were developed, for use at different spatial scales. The three FOOTPRINT tools share the same underlying science, based on the consistent identification of environmental characteristics driving the fate of agriculturally applied pesticides and their interpretation to parameterise state of the art modelling applications thus providing an integrated solution to pesticide risk assessment and management in the EU.

Fuzzy decision support system for assessing nitrogen fertilization in agricultural land
© Aristotle University of Thessaloniki (6/2009)
Modern conditional agriculture is based on whole field and mostly empirical approaches in defining and applying agrochemical inputs. The impact of fertilizing practices in the environment comprises of a crucial research matter. Soil nitrogen in its nitrate form is the most mobile nutrient, meaning that is easily leached out of soil system, increasing environmental risk.

The potential for application of bioactive compounds from birch bark as components of designer, functional composts are reviewed in this paper.

Comparative Life Cycle Assessment of the Production of Chemical Fertilizers versus Organic Fertilizers Derived From Poultry and Municipal Solid Wastes
© European Compost Network ECN e.V. (9/2006)
SUMMARY: This study was initiated to quantify the energy, material inputs and emissions, using the Life Cycle Assessment technique during the production of organic and chemical fertilizers and to assess and compare the environmental impacts of the production systems.

Contaminants and fertilizers – an assessment concept
© European Compost Network ECN e.V. (9/2006)
SUMMARY: With the resolution to the Federal Soil Protection Act on 17 March 1998 and its entry into force on 1 March 1999 including the corresponding Federal Soil Protection and Contaminated sites Ordinance on 12 July 1999 in Germany the preconditions for federal-unique soil protection were created, as well as benchmarks for a soil referred harmonisation of already existing operational approaches in environmental policy were settled.
