What is Germany's Internal and External Contribution?","description":"\u003cp\u003eBachelor Thesis from the year 2016 in the subject Geography \/ Earth Science - Cartography, Geographic Information Science and Geodesy, grade: 1,7, Humboldt-University of Berlin (Potsdam-Institut für Klimafolgenforschung), language: English, abstract: This work tries to answer the question of Germany¿s contribution to agricultural sources, through the total consumption of products and services. An environmentally-extended multi-regional input-output (¿MRIO¿) analysis is applied to track and account, direct and indirect, N-fertilizer use through international supply chains in 2007.\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003eFrom the resulting 31 kg N\/cap consumption based N-fertilizer use, 60% are embodied in imports and 40 % used internally. Comparing consumption based and production based val-ues shows, that Germany is a net-importing country of embodied N-fertilizer use with + 9 kg N\/cap. The total amount of N-fertilizer used for domestic production, imports and exports is 41 kg N\/cap. Due to low long-term storage of Nr in the agricultural system, Nr sources cor-respond approximately to Nr losses (Rockström et al. 2009, Bodirsky et al. 2014) that can cause (multiple; but not linearly-dependent) environmental impacts (Galloway et al. 2003, Bodirsky et al. 2014). Complexities from the nitrogen cascade (Galloway et al. 2008) and social-economic dynamics puts also locally manifested N- boundary processes on a global scale (Häyhä et al. 2014, 7), challenging (consumption based) national bottom up boundaries in view of external N-flows. A ¿footprint¿\/boundary perspective that compares current na-tional consumption based shoe sizes, per capita, with an equal, per capita, share of the PB N could provide a relevant estimation of the needed reductions to return to the safe operating space. For Germany a transgression of 270-310%, of which approximately two thirds is ex-ternal, and one third internal Nr from human intended fixation processes, is found. \u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003eIt can be concluded that German consumption drives substantial local nitrogen pollution in other countries and mitigation, especially through sufficiency approaches, is necessary to return to the safe operating space.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783346117007\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9783346117007","offer_id":39432756559965,"sku":"9783346117007","price":17.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/57c6062c-4b4c-4734-bf42-6091a0882fc6.jpg?v=1776918826","url":"https:\/\/shop.autorenwelt.de\/products\/the-transgression-of-the-planetary-nitrogen-boundary-what-is-germanys-internal-and-external-contribution-von-justus-eggers","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
