内容简介

Many environmental problems are caused or connected with the release of nitrogen compounds to the environment. With the doubling of the global nitrogen cycle due to human activities, also emissions have been on the rise. Impacts of nitrogen pollution range from human health (air pollution from particulate matter, nitrate drinking water pollution) to ecosystems damage (eutrophication or acidification of soils), from climate impacts (nitrous oxide is a greenhouse gas) to crop damage (as a consequence of tropospheric ozone). Addressing nitrogen compounds in an integrative manner allows for new perspectives, tackling a series of impact categories simultaneously and reaping the co-benefits of solving multiple environmental issues at once. This presentation will demonstrate – based on a series of modelling approaches – how measures across all economic sectors can be optimized and plausible scenarios of future situations developed at multiple spatial scales. Here air quality modelling or substance flow analysis (as in nitrogen budgets) accompanies the GAINS model in providing optimized solutions to achieve given environmental targets of diverse policy fields at lowest implementation costs.
