Zusammenfassung: Die vorliegende Arbeit hat zum Ziel, die Ursachen der irregulären Migration zu erklären, die Strukturen und Prozesse dieser Wanderung durch die Sahara zu analysieren. Außerdem sollen Lösungsmöglichkeiten zur Eindämmung der irregulären Migration aufgezeigt werden....

One of the major challenges that our world faces today and in the future is human-induced climate change. The primary cause of global warming, leading to climate change, is the burning of fossil fuels for energy and transport, which increases the concentration of greenhouse gases in the...

The issue of global warming has become a major topic in the international environmental debate. Alternative climate policy measures can be evaluated with the help of a simulation model that integrates economic and natural science considerations. A fully integrated assessment of the two-way...

The aim of this paper is to describe and discuss the weak and strong sustainability approach of assessing climate change and to show reasonable applications, weaknesses, possible improvements and linkages of both approaches. Main features of "weak" and "strong" sustainability approaches are...

This thesis aims at improving the current representation of adaptation in economic frameworks of climate change by a) accounting for the time-dependent evolution of the adaptive capacities of countries and b) quantifying unwelcome feedbacks of the adaptation process. In this context, it is...

[...] Die deutsche Land- und Forstwirtschaft ist von primären Klimafolgen wie stetig steigenden Durchschnittstemperaturen, veränderten Niederschlagsmustern und immer häufiger auftretenden, regional und saisonal sehr unterschiedlich ausgeprägten Extremwetterereignissen betroffen. Zudem...

We conduct an examination of the climate effect to analyze the historical dependence of grain production on temperatures and precipitation levels, and project this dependence to estimate the productivity of different grain types in the mid- and long-terms, given four greenhouse gas concentration...

Decarbonization requires the winding down of – economically – fully viable, if not highly prosperous, lines of economic activity. Different from past episodes of industrial restructuring revolving around the managed decline of sunset industries, accelerating climate change requires...
