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...

The standard indicators used to compare cross-country innovation are in the Global Competitiveness Report (GCR). But there are problems with aggregation and response bias with these largely self-reported measures (Hollanders and van Cruysen, 2008). We propose a theory-based metric using Data...

To meet their Kyoto targets under the Burden Sharing Agreement, most European countries plan to make use of the flexible project mechanisms “Clean Development Mechanism” (CDM) and “Joint Implementation” (JI). In addition, CDM and JI credits can be used by installations to fulfil their...

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...

Equal treatment for the present and the future was required in two axioms for sustainable development introduced by the author. This article shows that the two axioms are equivalent to awareness of physical limits in the long run future. We prove that two optimization problems are equivalent :...

In response to the world economic crisis, the international community should promote a mix of policies to sustain global recovery and create jobs through reducing carbon dependency, ecological degradation and poverty. Such a Global Green New Deal (GGND) requires implementation and coordination...

Climate change is one of the most urgent and severe problems on the international agenda and one of the basic factors that determine sustainability conditions. This paper attempts to reveal the connection between productive base sustainability for two large groups of countries, developed and...

Abstract: The Renewable Energy Source Act (EEG) promotes German biogas production in order to substitute fossil fuels, protect the environment, and prevent climate change. As a consequence, green maize production has increased significantly over the last years, causing negative environmental...

Land use and land use change are determined as much by economic and institutional drivers as they depend on bio-physical conditions. Future pathways of socio-economic and environmental systems can only be assessed with scenarios which describe possible future paths of development. For this...

Traditionally, observed fluctuations in aggregate economic time series have been mainly modelled as being the result of exogenous disturbances. A better understanding of macroeconomic phenomena, however, surely requires looking directly at the relations between variables that may trigger...
