Der Globalisierungsprozess der Weltwirtschaft und seine Auswirkungen auf globale Stoffströme werden kontrovers diskutiert. Die einen sehen darin einen Wohlfahrtsgewinn für alle Volkswirtschaften, die sich der internationalen Arbeitsteilung geöffnet haben, die anderen befürchten soziale...

The development of the agricultural sector and the improvement of the food security situation are seen as essential components to sustainable development in Africa. However, continuing population growth, impacts of climate change and environmental degradation add to an unprecedented combination...

This paper explores the interrelations between economic growth, international trade and environmental degradation both theoretically and empirically. Panel data from developed and developing countries for the period of 1980 to 2003 is used and previous critique, especially on the econometric...

This study attempts a numerical simulation of potential CCS (carbon dioxide capture and storage) use by using a modified version of the DICE (Dynamic Integrated model on Climate and Economy) model (Nordhaus, 1994; Nordhaus and Boyer, 2000). In DICE, CO2 emissions are controlled to the extent in...

This paper presents a Computable General Equilibrium (CGE) model for the analysis of environmental policies towards mining activities, and shows for the case of South Africa how it can be implemented numerically. The CGE model belongs to the class of static, trade-focussed models along the lines...

In the presence of rising carbon concentrations more attention should be given to the role of the oceans as a sink for atmospheric carbon. We do so by setting up a simple dynamic global carbon cycle model with two reservoirs containing atmosphere and two ocean layers. The net flux between these...

Genetische Ressourcen sind Lebewesen, die genetischen Informationen in sich tragen, welche für die biotechnologische Forschung und Entwicklung von Bedeutung sind. Angesichts eines sich beschleunigenden weltweiten Artenverlustes stellt sich die Frage, ob durch den privaten Handel mit genetische...
