    Contested, Violated but Persistent: Presidential Term Limits in Latin America and Sub-Saharan Africa: Introduction to Special Issue

    The term limits of presidents as a crucial institutional feature to safeguard democracy have often been contested by incumbents. The authors of this article argue that bringing together knowledge on Latin America and Sub-Saharan Africa provides new empirical and theoretical insights.

    Sequences of Presidential-Term-Limit Reforms: Latin America and sub-Saharan Africa

    In this article the authors take a longitudinal view on presidential-term-limit reforms in Latin America and sub-Saharan Africa since the third wave of democratization. Many countries (re)introduced the measure as a democratic safeguard against abuse of power; since then, it has been repeatedly challenged.

    The Political Limits of Presidential Impeachment: Lessons from Latin America

    In presidential democracies, impeachment proceedings are an important mechanism for controlling executive powers. GIGA expert Prof. Mariana Llanos and Prof. Leiv Marsteintredet show in the GIGA Focus that impeachment proceedings can, however, also open the door to party-political interests and opportunism.

    COVID-19 and Executive Personalization in Sub-Saharan Africa, Asia, Latin America and the MENA Region

    In response to the COVID-19 pandemic, political leaders reacted by containment measures that, next to combating the spread of the pandemic, also presented a window of opportunity to bolster executives’ personal grasp on power. Personalization of power has been particularly worrying in the Global South where constraints on the chief executives were often already weak prior to the pandemic. This project assesses the impact of the COVID-19 pandemic on the personalization of executive power in 36 countries of the Global South.

    Democratic Institutions in the Global South (DEMINGS)

    This project contributes new knowledge on the functioning of democratic institutions in the Global South, their (in)efficacy to constrain powerful executives, and the effects of particular institutions on both democratic quality and regime stability. The focus is on countries with presidential constitutions, i.e., those with directly elected presidents, an institutional choice that extended worldwide in the last decades.

    This cooperation project researches two important rules defining the presidential mandates, i.e. presidential term limits and succession rules, and their intersection in the presidential regimes of Latin America and sub-Saharan Africa.

    Democratic Institutions and Policy Making

    This seminar studies the formal institutions that must converge in order to deliver a policy outcome. We concentrate on five major themes: the electoral cycle, dynamics of executive-legislative relations, decision-making between national and sub-national levels of government, the judiciary and the protection of rights, and mechanisms for direct democracy.

    Democratization and Autocratization in the Global South

    University of Erfurt Erfurt

    According to the latest Freedom House’s report, global democracy is in further decline, with the number of countries experiencing deterioration outnumbering those with improvements by the largest margin since this negative trend began to be observed 15 years ago. In this course, students are familiarized with three successive developments in global democracy as well as with the political science concepts and literature that have accompanied these trends: first, the inception of the third wave of democratization in the 1970s-1990s; second, democratic recession and problems in the quality of consolidating democracies; third, developments leading to democratic erosion and backsliding. Students will learn to work with key concepts and indicators related to each of these trends. They will work with case studies.
